  •                             UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF COLUMBIA
    ADAM STEELE, BRITTANY
    MONTROIS, and JOSEPH HENCHMAN,
    on behalf of themselves and all others
    similarly situated,
    Plaintiffs,
    v.                                                        Case No. 1:14-cv-1523-RCL
    UNITED STATES OF AMERICA,
    Defendant.
    MEMORANDUM OPINION
    This case concerns the Internal Revenue Service's ("IRS" or "the agency") assessment of
    fees to income tax return preparers for its issuance and renewal of Preparer Tax Identification
    Numbers ("PTINs"). Plaintiffs, a class ofreturn preparers, sued the United States for declaratory,
    injunctive, and monetary relief in this Court, arguing that the IRS lacked authority under the
    Independent Offices Appropriations Act ("IOAA"), 
    31 U.S.C. § 9701
    , to charge those fees. This
    Court agreed, granted summary judgment to plaintiffs, and enjoined the IRS from continuing to
    assess fees for PTIN registrations and renewals. Steele v. United States ("Steele I"), 
    260 F. Supp. 3d 52
    , 63---67 (D.D.C. 2017). On appeal, however, the Circuit vacated this Court's judgment,
    holding that that statute indeed authorized PTIN fees, and remanded for consideration of whether
    the fee amounts were excessive. Montrois v. United States, 
    916 F.3d 1056
    , 1062---68 (D.C. Cir.
    2019).
    Before the Court on remand are the parties' cross-motions for summary judgment, ECF
    Nos. 173, 175. Plaintiffs argue that many of the expenses used to justify the amount of the PTIN
    fees are unnecessary to the maintenance of the PTIN system and therefore those fees are excessive
    1
    in violation of the IOAA. The government moves only for partial summary judgment, conceding
    that the IRS unlawfully included certain expenses in its PTIN fee calculations but maintaining that
    the agency was within its authority to include others. The government further argues that it is
    entitled to an offset to its liability for sums it could have charged in fees while it was enjoined by
    this Court from assessing them. For the reasons that follow, the Court will GRANT in part and
    DENY in part plaintiffs' motion, GRANT in part and DENY in part the government's motion,
    and REMAND to the IRS to determine an appropriate refund for the class in a manner consistent
    with the IOAA.
    I.   BACKGROUND
    A. Statutory and Regulatory Background
    Both this Court and the Circuit have set out the statutory and regulatory background of this
    case extensively in prior opinions. See Steele I, 
    260 F. Supp. 3d at 56-58
    ; Montrois, 
    916 F.3d at
    1058----60; Steele v. United States ("Steele III"), No. 14-cv-1523-RCL, 
    2020 WL 7123100
    , at *1-2
    (D.D.C. Dec. 4, 2020). Accordingly, the Court will summarize that background here only as
    necessary to resolve the pending cross-motions for summary judgment.
    The Internal Revenue Code defines a "tax return preparer" as "any person who prepares
    for compensation, or who employs one or more persons to prepare for compensation, any return
    of' or "claim for refund of' federal income taxes. 
    26 U.S.C. § 7701
    (a)(36)(A). While the Code
    does not set professional standards or licensing requirements for return preparers, Congress
    enacted a statute in 1976 authorizing the IRS to require them to list their social security numbers
    for identification purposes on returns they prepared. See Tax Reform Act of 1976, Pub. L. No. 94-
    455, § 1203(d), 
    90 Stat. 1520
    , 1691.
    In 1998, Congress amended that statute to authorize the IRS to permit return preparers to
    list a separate identification number issued by the agency instead of a social security number. 26
    
    2 U.S.C. § 6109
    (a), (d). The IRS promulgated an implementing regulation the following year
    creating the PTIN program and allowing, but not requiring, return preparers to list the PTINs it
    issued in lieu of a social security number on returns. Furnishing Identifying Number of Income
    Tax Return Preparer, 
    64 Fed. Reg. 43,910
     (Aug. 12, 1999) (codified at 26 C.F.R. pt. 1).
    In 2010 and 2011, the IRS issued a series of regulations expanding its regulatory reach
    over return preparers. As a part of that effort, the IRS created a mandatory credentialing process
    for preparers who are not attorneys or certified public accountants, including a background check,
    a competency exam, and ongoing education requirements. See Regulations Governing Practice
    Before the Internal Revenue Service, 
    76 Fed. Reg. 32,286
    , 32,286-87 (June 3, 2011 ). The IRS also
    expanded the PTIN program, retooled it as a broader information-gathering system regarding
    preparers, made obtaining and renewing PTINs mandatory for preparers, and began chargi_ng a fee
    to obtain and renew one. See Furnishing Identifying Number of Tax Return Preparer, 
    75 Fed. Reg. 60,309
    , 60,309-10 (Sept. 30, 2010); User Fees Relating to Enrollment and Preparer Tax
    Identification Numbers, 
    75 Fed. Reg. 60,316
    , 60,316, 60,319 (Sept. 30, 2010).
    To support the expanded program, the IRS organized a new Return Preparer Office
    ("RPO") with multiple departments, including, as relevant here, the Suitability Department, the
    Compliance Department, and various departments providing support to the entire office. The
    Suitability Department "was responsible for checking personal tax compliance, checking
    professional designation, matching prisoner lists, checking compliance of Enrolled Agents [] and
    Enrolled Retirement Plan Agents [], checking compliance with the Annual Filing Season Program
    [], Former Employee EA Enrollment Applications, and matching Specially Designated Nationals
    [] lists." Pls.' Statement ofUndisputed Material Facts ("PSUMF") ,r 81, ECF No. 177-30 (internal
    quotation marks and citation omitted); Def' s Resp. to PSUMF ("DRPSUMF") ,r 81, ECF No. 184-
    3
    1. The Compliance Department performed data analytics regarding compliance with PTIN
    reporting requirements, investigated so-called "ghost preparers" who failed to use a PTIN or used
    someone else's PTIN or an invalid number, and processed disciplinary referrals of preparers.
    PSUMF ,i,i 82-85; DRPSUMF ,i,i 82-85.
    After the IRS implemented its new return preparer regulations, a group of return preparers
    sued the IRS, arguing that its new preparer credentialing process was unlawful because the statute
    that the agency used to justify it, 
    31 U.S.C. § 330
    , regarding persons practicing before the IRS, did
    not reach return preparers. See Loving v. IRS, 
    742 F.3d 1013
    , 1015-16 (D.C. Cir. 2014). The
    District Court granted summary judgment to the plaintiffs, invalidating the credentialing
    requirement, and the Circuit affirmed. 
    Id. at 1021-22
    . Loving thus invalidated many of the RPO
    activities that the PTIN fees funded. However, it left undisturbed the regulations requiring all
    return preparers to obtain and renew PTINs and to pay a fee for doing so.
    B. The IRS's PTIN fee calculations
    The following is a summary of the PTIN and vendor fees that the IRS charged return
    preparers between Fiscal Year ("FY") 2011 and 2017 and from FY 2021 to the present, 1 as well
    as the various cost models that the IRS used to set those amounts.
    1. Fees based on the 2010 Cost Model
    In 2010, the IRS completed a Cost Model estimating that the annual PTIN registration and
    renewal fee should be set at $50, the amount that the agency would ultimately charge from the new
    PTIN system's implementation in FY 2011 through 2015. Def. 's Statement of Undisputed Material
    Facts ("DSUMF") ,i,i 66, 71-73, ECF No. 173-2; Pls.' Resp. to DSUMF ("PRDSUMF") ,i,i 66,
    1
    As explained below, the IRS did not assess PTIN fees between FY 2018 and 2020 because of this Court's order
    enjoining it from doing so, which the Circuit later vacated.
    4
    71-73, ECF No. 187-2. The government summarizes the activities whose expected costs the IRS
    used to reach that number as follows:
    •   Communications & Customer Support
    •   IT Development & Implementation
    •   Program Compliance (Professional Designation Checks
    (PDC), Personal Tax Compliance (PTC), Criminal
    Background Checks (CBC), and administrative support)
    •   Management and supervisory costs (entitled OPR/PMO
    Operations Support)
    •   Foreign Preparer Processing
    DSUMF ,r 64; see 2010 Cost Model, Ex. 13 to Defs.' Mot. for S.J., ECF No. 174-8. Plaintiffs add,
    and the government does not dispute, that the "Program Compliance" component "also included
    'Verify[ing] Return Preparers' Self-Reported Tax Compliance,' 'Develop[ing] processes for
    Identifying and Treating Return Preparers Filing w/o PTIN or Incorrect PTIN,' and 'Verify[ing]
    Return Preparers' Self Certified Continuing Education."' PRDSUMF ,r 64 (alterations in original)
    (quoting Ex. U to Pls.' Mot. for S.J. at 5, ECF No. 176-21); see PSUMF      ,r 34; DRPSUMF ,r 34.
    Although the IRS conducted a "biennial review" of PTIN costs and produced a 2013 Cost Model,
    estimating that the PTIN fee should increase to $54.47, the IRS elected to keep the fee at $50 for
    the next two years. DSUMF ,r,r 84-85; PRDSUMF ,r,r 84-85.
    The government now concedes that the IRS should not have included the personal tax
    compliance, criminal background check, self-reported tax compliance, or continuing education
    activities in its calculations, because those activities were invalidated by Loving. DSUMF   ,r 68.
    Removing the costs associated with those items from the original calculations, the government
    asserted at the time of its opening summary judgment brief that the appropriate PTIN fee based on
    the 2010 Cost Model would have been $ 17. 
    Id.
          ,r,r 69-70   (citing 2010 Cost Model at 3). The
    government made further concessions with respect to the 2010 Cost Model after filing its opening
    brief and now only defends a PTIN fee of$14.05 for FY 2011 through 2013. See Def 's Reply at
    5
    10-11, ECF No. 203; Second Deel. of Carol A. Campbell ("Second Campbell Deel.")         if 6, ECF
    No. 203-1. The government makes similar concessions with respect to the 2013 Cost Model, which
    it now cites as an appropriate measure of fees for FY 2014 and 2015, and asserts that the fee for
    those years should have been $37.25. DSUMF ,r,r 86-90; Def 's Reply at 11-12.
    In addition to the PTIN fees themselves, the IRS required preparers to pay a "vendor fee"
    to Accenture, a third-party contractor that the agency hired to develop, maintain, and operate the
    computer system responsible for PTIN registrations. DSUMF ,r,r 112-13; PRDSUMF ,nr 112-13.
    From FY 2011 to 2015, that fee was set by the contract between the IRS and Accenture at $14.25
    for new PTIN registrations and $13 for PTIN renewals. DSUMF ,r,r 115-18; PRDSUMF ,r,r 115-
    18, 123. The government continues to defend t~e vendor fees in full. See Def.'s Opp'n at 27-29,
    ECFNo. 183.
    In sum, from FY 2011 to 2015, preparers registering for a PTIN for the first time paid a
    $50 PTIN fee and a $14.25 vendor fee, for a total of $64.25; and preparers renewing their PTIN
    paid a $50 PTIN fee and a $ 13 vendor fee, for a total of $63. The government now concedes that
    the PTIN fee associated with each of those numbers should have been only $17 for FY 2011
    through 2013 and $37.25 for FY 2014 and 2015. Thus, the government impliedly asserts that the
    total amount charged should have been $31.25 for new registrants and $30 for renewing registrants
    during FY 2011 through 2013 and $51.50 for new registrants and $50.25 for renewing registrants
    during FY 2014 and 2015.
    2. Fees based on the 2015 Cost Model
    In 2015; the IRS completed a second biennial review and issued a new Cost Model,
    estimating that the PTIN fee to be charged in FY 2016 and 2017 should be set at $3 3. 2015 Cost
    Model at 1, Ex. 21 to Def.'s Mot. for S.J., ECF No. 174-12; DSUMF ,r 94; PRDSUMF ,r 94. That
    6
    number was lower than the original $50 fee in part because of certain activities that the Circuit
    invalidated in Loving. DSUMF ,r 95; PRDSUMF ,r 95 . The government later conceded additional
    costs in the 2015 Cost Model that it determined in a subsequent biennial review to be improper
    based on Loving and now asserts that the proper PTIN fee for FY 2016 and FY 201 7 would have
    been approximately $24. DSUMF ,r 103; PRDSUMF ,r 103.
    The IRS also continued to require return preparers to pay the vendor fee to Accenture. For
    FY 2016, the vendor fee remained at $14 for new registrations and $13.25 for renewals. DSUMF
    ,r,r 120-23; PRDSUMF ,r,r 120-123. By FY 2017, a new contract between the IRS and Accenture
    had taken effect, and the vendor fee increased to $1 7 for both new registrations and renewals.
    DSUMF ,r,r 124-25; PRDSUMF iMf 124-25.
    In sum, in FY 2016, preparers registering for a PTIN for the first time paid a $33 PTIN fee
    and a $14 vendor fee, for a total of $47; and preparers renewing their PTIN paid a $33 PTIN fee
    and a $13.25 vendor fee, for a total of $46.25. In FY 2017, preparers paid a $33 PTIN fee and a
    $17 vendor fee, for a total of $50, regardless of whether they were registering for the first time or
    renewing their registrations. The government now concedes that the PTIN fees associated with
    those numbers should have been $24. Thus, the government impliedly asserts that the total amount
    charged should have been $38 for new registrants and $37.25 for renewing registrants in FY 2016
    and $41 for all preparers in FY 201 7.
    3. Fees based on the 2019 Cost Model
    As explained below, this Court enjoined the assessment of PTIN fees in 2017 and the
    Circuit vacated that decision in 2019. In 2019, the IRS completed another biennial review and
    produced another Cost Model estimating that the PTIN fee should be approximately $21 for both
    new registrations and renewals. DSUMF ,r,r 107-108; PRDSUMF iMf 107--08. The new fee of $21
    7
    took effect in August 2020 and remained in effect through at least FY 2022. 2 See Preparer Tax
    Identification Number (PTJN) User Fee Update, 
    85 Fed. Reg. 43433
     (July 17, 2020).
    The vendor fee to Accenture also remained in force. Beginning in FY 2018 and continuing to
    the present, the vendor fee is set at $14.95 for both registrations and renewals. DSUMF                     ,r 133;
    PRDSUMF ,r 133. While the aforementioned injunction was in effect and the IRS was unable to charge
    PTIN fees, the IRS itself paid the vendor fee, which was set by contract, to Accenture for each
    registration or renewal. DSUMF ,i 134; PRDSUMF ,i 134.
    In sum, in FY 2021 and 2022, preparers paid a $21 PTIN fee and a $14.95 vendor fee, for a
    total of $35.95, each year for a registration or renewal.
    C. The Present Case
    The present case began in 2014, after the Circuit's decision in Loving, when a putative
    class of tax-return preparers filed an action in this Court against the United States challenging the
    regulations making PTINs mandatory and imposing a fee on the issuanc.e and renewal of PTINs.
    See Compl., ECF No. 1. The plaintiffs sought review of the PTIN fees under the Administrative
    Procedure Act ("AP A") and requested declaratory and injunctive relief, as well as an award of
    restitution refunding the PTIN fees they had paid. 
    Id.
     3 On August 8, 2016, the Court certified a
    class of"[ a]ll individuals and entities who have paid an initial and/or renewal fee for a PTIN,
    excluding Allen Buckley, Allen Buckley LLC, and Christopher Rizek," ECF No. 63, and
    2
    Plaintiffs ask the Court to take judicial notice of an apparent decrease in the PTIN fee amount for FY 2023 by $5.20.
    See Pls.' Request for Jud. Notice, ECF No. 218. For reasons explained below, later calculations are not relevant to the
    excessiveness of the FY 20 J 1-2017 PTIN fees, which are the only ones at i ue in this opinion. Accordingly, the
    Court will deny plaintiffs' request that it take judicial notice.
    3
    Although the initial complaint did not mention the APA, plaintiffs' first amended complaint filed in August 2015,
    clarified that they were challenging the PTIN fees as unlawful agency action under the Adm inistrative Procedure
    Act, 
    5 U.S.C. § 706
    (2)." First Am. Compl. ,r 42.
    8
    appointed Motley Rice LLC as counsel for the dass. 4 The following month, the parties cross-
    moved for summary judgment. ECF Nos. 66, 67.
    On June 1, 2017, this Court granted in part and denied in part both parties' summary
    judgment motions. Steele I, 
    260 F. Supp. 3d at
    67-(j8, First, the Court held that the Internal
    Revenue Code authorized the IRS to require the use of PTINs, and that the agency's decision to
    do so was not arbitrary and capricious under the APA. 
    Id.
     at 62-(j3. Second, the Court held that
    the IOAA did not authorize the IRS to charge a fee for the issuance or renewal of PTINs, reasoning
    that PTINs did not constitute a "service or thing of value provided by [an] agency," 
    31 U.S.C. § 9701
     (b), within the meaning of that statute-the only proper basis for a fee under it, Steele I, 
    260 F. Supp. 3d at
    63-(j7_ The Court therefore enjoined the IRS from charging a PTIN fee going
    forward. ECF No. 82. Only the government appealed. See Notice of Appeal, ECF No. 90.
    The government then filed a motion for a stay pending appeal of the Court's injunction
    against charging a PTIN fee. ECF No. 84. The Court denied that motion. Steele v. United States
    ("Steele II"), 
    287 F. Supp. 3d 1
    , 6 (D.D.C. 2017).
    On appeal, the Circuit vacated and remanded in a March 1, 2019 decision. Montrois, 
    916 F.3d at 1068
    . The Circuit first ruled for the government on the IOAA ground, holding that the
    PTIN system was a service that provided return preparers a private benefit-specifically,
    "protect[ing] the confidentiality of their personal information"-and therefore that the statute
    authorized the imposition of a fee to recoup the costs of "generating PTINs and maintaining a
    database of PTINs." 
    Id.
     at 1062-(j7. The Circuit then dispatched an alternative argument that this
    Court never reached: that the decision to impose a fee was arbitrary and capricious under the AP A.
    4
    As reflected on the public docket, the persons and firm excluded from the class are also plaintiffs' counsel.
    9
    
    Id.
     at 1067--68. Because only the government appealed, the Circuit's decision did not disturb this
    Court's holding that the IRS was authorized to require preparers to obtain PTINs.
    On remand, this Court entered a new scheduling order and the parties commenced fact
    discovery on the reasonableness of the fees charged. See ECF Nos. 100, 127. That is when
    infighting among plaintiffs' counsel threatened to derail the case. Mr. Buckley, co-counsel for
    plaintiffs, evidently could not reach an agreement to share control of the case with class counsel
    Motley Rice LLC, and on January 23, 2020, he filed a motion to be appointed as lead counsel for
    the class. ECF No. 118. The Court denied that motion. ECF No. 126.
    Without the Court's assistance in wresting control of plaintiffs' case from his co-counsel,
    Mr. Buckley decided to go rogue. He filed two motions, purportedly on behalf of the class, but
    against class counsel Motley Rice LLC's wishes: one for a preliminary injunction against requiring
    registered preparers to renew their PTINs and another for leave to file an amended complaint
    adding allegations that the PTIN renewal (as opposed to registration) requirement was unlawful
    and that the PTIN fees charged after 2020 were excessive. ECF Nos. 128, 133. Both factions of
    plaintiffs' counsel and the government eventually reached a stipulation regarding the latter motion,
    and the government consented to the addition of allegations about the post-2020 fee amounts but
    not the renewal requirement. ECF No. 139.
    On December 4, 2020, the Court denied the preliminary injunction motion and granted in
    part and denied in part the motion for leave to file an amended complaint. Steele Ill, 
    2020 WL 7123100
    , at *7. The Court noted that the government stipulated to the addition of allegations about
    the post-2020 fees but reasoned that the so-called "allegations" in the proposed amended complaint
    were added after undue delay and that adding them to the complaint would be futile because they
    were simply "naked legal conclusions" about the agency's authority to require registered preparers
    10
    to renew their PTINs. 
    Id. at *5-6
    . Accordingly, the Court granted leave to amend the complaint
    ,_ with respect to the former but not the latter. 
    Id.
     The Court then denied the preliminary injunction
    motion because the operative complaint contained no allegations about the legality of requiring
    registered preparers to renew their PTINs. 
    Id. at *6-7
    .
    On March 23, 2022, the parties filed their cross-motions for summary judgment on the
    excessiveness of the PTIN and vendor fees. ECF Nos. 173, 177. On May 12, 2022, the parties filed
    their opposition briefs, ECF Nos. 183, 185, and Mr. Buckley, still unwilling to yield his claim as
    class-counsel-in-exile, filed a short supplemental brief in support of plaintiffs' motion, ECF No.
    188. 5 The parties filed their replies on July 8, 2022, ECF Nos. 203, 207-4, and one week later,
    plaintiffs moved for leave to file a surreply, ECF No. 211, which the Court will GRANT. The
    summary judgment, motions are now ripe for review.
    II.     LEGAL STANDARDS
    A. Summary Judgment and the APA
    In ordinary civil actions, summary judgment is appropriate "if the movant shows that there
    is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of
    law." Fed. R. Civ. P. 56(a). A fact is "material" ifit "might affect the outcome of the suit under
    the governing law." Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 248 (1986). "[S]ummary
    judgment will not lie if the dispute about a material fact is 'genuine,' that is, if the evidence is such
    that a reasonable jury could return a verdict for the nonmoving party." 
    Id.
     A court evaluating a
    summary judgment motion must "view the evidence in the light most favorable to the nonmoving
    5
    Mr. Buckley also filed a motion to modify the proposed summary judgment order filed by his co-counsel. ECF No.
    206. Because there is no indication on the docket that class counsel agrees to that modification, Court will DENY that
    motion.

    party and draw all reasonable inferences in its favor." Arthridge v. Aetna Cas. & Sur. Co., 
    604 F.3d 625
    , 629 (D.C. Cir. 2010).
    "But when, as here, the court is reviewing a final agency action under the AP A, the standard
    set forth in Rule 56(a) does not apply." Ardmore Consulting Grp., Inc. v. Contreras-Sweet, 
    118 F. Supp. 3d 388
     (D.D.C. 2015). Rather, "the function of the district court is a more limited one: 'to
    determine whether or not as a matter of law the evidence in the administrative record permitted
    the agency to make the decision it did."'

    , 198 (D.D.C. 2011)). 6 The reviewing court must make that determination in
    accordance with the AP A's judicial review provision, which requires the court to set aside agency
    action that is unlawful for any of a variety of reasons, including, as relevant here, that it is
    "arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law," or "in
    excess of statutory jurisdiction, authority, or limitations, or short of statutory right." 
    5 U.S.C. § 706
    (2)(A), (C).
    B. TheIOAA
    Although the AP A is the procedural vehicle for plaintiffs' challenge to the PTIN fees, the
    substance of that challenge alleges that the IRS assessed those fees in excess of its statutory
    authority to set user fees under the IOAA. The IOAA provides in relevant part as follows:
    The head of each agency (except a mixed-ownership Government
    corporation) may prescribe regulations establishing the charge for a
    service or thing of value _provided by the agency. Regulations
    prescribed by the heads of executive agencies are subject to policies
    prescribed by the President and shall be as uniform as practicable.
    Each charge shall be-
    ( 1) fair; and
    (2) based on-
    6 The Court acknowledges that there is no administrative record in this case and that it has allowed the parties to
    engage in fact discovery and produce an ordinary smnmary-judgmen.t- like record. Nevertheless, because plaintiffs
    seek judicial review of an agency action-specifically, the setting of the PTIN and vendor fees----the Court will
    evaluate the summary judgment motions under the standard used in AP A cases.
    12
    (A) the costs to the Government;
    (B) the value of the service or thing to the recipient;
    (C) public policy or interest served; and
    (D) other relevant facts.
    31 U.S.C. § 970l(b).
    "To justify a fee under the [IOAA], ... an agency must show (i) that it provides some kind
    of service in exchange for the fee, (ii) that the service yields a specific benefit, and (iii) that the
    benefit is conferred upon identifiable individuals." Montrois, 
    916 F.3d at
    1062---63. The Circuit
    has already held that "the PTIN fee satisfies those conditions." 
    Id. at 1063
    .
    As for the factors to be considered in calculating the amount of the fee, decisions
    interpreting the IOAA have given it a limited construction. In Nat 'l Cable Television Ass 'n, Inc.
    v. United States ("NCTA I"), 
    415 U.S. 336
     (1974), interpreting an earlier, substantially similar
    version of the statute, the Supreme Court held that the "'value to the recipient' is ... the measure
    of the authorized fee" under the statute, because that construction avoids a concern that by
    calculating a "fee" based on the public interest or other factors, an agency would assess what is
    functionally a tax, potentially usurping Congress's exclusive power of taxation. 
    Id.
     at 340-43
    (citing U.S. Const. Art. I, § 8); see also Fed. Power Comm 'n v. New England Power Co., 
    415 U.S. 345
    , 349-51 (1974) (companion case).
    Applying that precedent to the current version of the statute, the Circuit has identified two
    constraints on the costs that agencies may pass off to users under the statute. First, "[a]n agency
    may not charge more than the reasonable cost it incurs to provide a service, or the value of the
    service to the recipient, whichever is less." Engine Mfrs. Ass'n v. Envt'l Protection Agency, 
    20 F.3d 1177
    , 1180 (D.C. Cir. 1994). That calculation need not be perfect-the activities charged for
    need only be "reasonably related" to the cost to the agency and the value to the recipient, and the
    total may include both "direct and indirect" costs associated with the service provided. Nat 'l Cable
    13
    Television Ass 'n v. Fed. Comm. Comm 'n ("NCTA If') , 
    554 F.2d 1094
    , 1107 (D.C. Cir. 1976); see
    also Montrois, 
    916 F.3d at 1066
    . Second, "when the specific agency activity in question produces
    an independent public benefit, the agency must reduce the fee that it would otherwise charge by
    that portion of the agency' s costs attributable to that public benefit." Cent. & S. Motor Freight
    TariffAss'n, Inc. v. United States, 
    777 F.2d 722
    , 729 (D.C. Cir. 1985) (emphasis in original).
    For more detailed instructions on the factors to be considered when calculating costs,
    agencies typically look to an Office of Management and Budget ("OMB") guidance document
    known as Circular A-25. See Office of Mgmt. and Budget, Circular A-25 (Rev.),
    https://wW\v.whitehouse.gov/wp-conten uploads/2017/ 11/Cir ul ar-025.pdf(last accessed Jan. 17,
    2023). Circular A-25 expresses a "[g]eneral policy" that "[a] user charge . .. will be assessed
    against each identifiable recipient for special benefits derived from Federal activities beyond those
    received by the general public." 
    Id.
     § 6. It also lists the types of costs of carrying out an activity
    that an agency should include in its estimation of that activity' s "full cost," such as "[d]irect and
    indirect personnel costs," "[p]hysical overhead," "management and supervisory costs," and "[t]he
    costs of enforcement, collection, research, establishment of standards, and regulation." Id.
    § 6( d)( 1). Both the Supreme Court and the Circuit have cited earlier versions of Circular A-25 with
    approval, specifically for the proposition contained in its general policy statement that it is the
    private benefit to an identifiable beneficiary, rather than the public benefit, that should be the
    measure of an agency user fee. See New England Power Co., 
    415 U.S. at 349-50
    ; Seafarers Intern.
    Union ofN Am. v. US. Coast Guard, 
    81 F.3d 179
    , 183 (D.C. Cir. 1996). However, neither court
    has held that an IOAA fee is automatically lawful simply because the agency followed Circular
    A-25's guidance regarding the types of costs to use in estimating the full cost of carrying out an
    activity.
    14
    III.     DISCUSSION
    The Court now turns to the parties' cross-motions for summary judgment. Plaintiffs move
    for summary judgment only as to liability, arguing that the FY 2011 through 2017 PTIN and
    vendor fees were excessive as a matter of law and that the IRS may not ask any more than a basic
    list of biographical questions on the PTIN application. 7 The government seeks partial summary
    judgment, conceding that portions of the FY 2011 through 2017 PTIN fees were excessive but
    continuing to defend other portions of those fees and all of the vendor fees, and arguing that it is
    entitled to an "offset" to any award of restitution based on the amount it could have charged return
    preparers from FY 2017 to 2020 but was unable to because of the Court's prior injunction against
    the collection of PTIN fees.
    Because the issues raised by both motions are so intertwined, the Court will discuss them
    together. First, the Court will determine the extent to which the disputed fees were unlawfully
    excessive under the IOAA. Second, the Court will consider the government's claimed offset to an
    award of restitution. Third, the Court will briefly discuss plaintiffs' argument that the IRS may
    only ask for limited biographical information on PTIN applications. Finally, the Court will
    determine the appropriate remedy.
    For the reasons that follow, the Court holds that the FY 2011 through 2017 PTIN and
    vendor fees were excessive as a matter of law, that the government is not entitled to an offset to
    7
    Although the operative complaint includes allegations that the PTIN fees charged after Montrois, beginning in 2020,
    are also excessive, see Second Am. Compl. ,r,r 55-59, plaintiffs' summary judgment motion does not address that
    issue. That is apparently because the parties jointly stipulated that they would "first seek adjudication and a partial
    final judgment-by way of summary judgment, trial, appeal, and/or settlement-of the disputes related to the 2010-
    17 Claim." Stip. Re: Post-2019 PTIN Fees ,r 3, ECF No. 144. Nevertheless, the government's summary judgment
    motion defends the post-2020 PTIN and vendor fees in full, and plaintiffs' opposition to that motion does not discuss
    the issue. See Def.'s S.J. Mem. at 25-28, ECF No. 173-1; Pls.' Opp'n, ECF No. 185. Ordinarily, "[w]here a party fails
    to address arguments raised by the opposing party's motion for summary judgment, the Court may treat those
    arguments as conceded." Comptel v. FCC, 
    945 F. Supp. 2d 48
    , 55 (D.D.C. 2013). But given the parties' joint
    stipulation, which the government seems to have disregarded, the Court will simply decline to adjudicate the
    excessiveness of the post-2020 fees at this stage without deeming plaintiffs to have conceded that point.
    15
    restitution for fees it was unable to charge due to the Court's prior injunction, and that plaintiffs'
    challenge to the questions asked on the PTIN application is improperly raised. The Court will
    remand to the IRS to determine an appropriate refund to the class.
    A. The Excessiveness of the PTIN and Vendor Fees
    Plaintiffs argue that the PTIN and vendor fees charged in FY 2011 through 2017 were
    excessive because they included costs not strictly necessary to the administration of the PTIN
    system. See Pls.' S.J. Mem. at 16-24, ECF No. 177-29. The government concedes that certain
    costs were wrongfully included in the PTIN calculations but defends the inclusion of other costs
    that plaintiffs dispute. See Def.'s SJ. Mem. at 12-25, ECF No. 173-1; Def.'s Opp'n at 8-29.
    As an initial matter, the parties disagree about the proper standard for evaluating plaintiffs'
    challenge to the PTIN and vendor fee amounts. Plaintiffs argue that the Court must determine for
    itself whether any given expense was "necessary" to the provision of the private benefit justifying
    the imposition of the fee-here, protecting return preparers' identities-without giving any
    deference to the agency's determination of that question. See Pls.' S.J. Mem. at 16-17. The
    government argues that because the Circuit in Montrois held that PTINs confer a private benefit,
    any direct or indirect cost "reasonably related" to the overall PTIN scheme that was not invalidated
    by Loving was allowable as a basis for the PTIN fees, and the Court must give "more than mere
    deference or weight" to the agency's determination of what expenses are so related. Def.'s S.J.
    Mem. at I 0-12, 16-17. Both proposed standards miss the mark.
    Plaintiffs' proposed "necessary" standard takes a word from a single Circuit opinion out of
    context and makes out the scope of judicial review of IOAA fees to be more aggressive than it is
    supposed to be. Plaintiffs make much of the Circuit's pronouncement in Elec. Indus. Ass 'n,
    Consumer Elec$. Grp. v. FCC, 
    554 F.2d 1109
     (D.C. Cir. 1976), that "a fee [may] only charge for
    16
    those expenses which are necessary to service the applicant or grantee." 
    Id. at 1115
     (emphasis
    added). But the next sentence of that decision, which states that"[ e]xpenses incurred to serve some
    independent public interest cannot, under [NCTA I], be included in the cost basis for a fee," makes
    clear that the Circuit's emphasis was not on the degree of necessity to the provision of the service,
    I
    but on the contrast between funding the provision of private benefits and benefits to the public at
    large.   
    Id.
       In NCTA II, decided the same day, the Circuit stated that an IOAA fee "must be
    reasonably related to those attributable direct and indirect costs which the agency actually incurs
    in regulating (servicing) the industry," 554 F.2d at 1107 (emphasis added), language similar to
    which the Circuit has repeated in subsequent decisions, see, e.g., Seafarers, 81 F .3d at 185 (holding
    that IOAA fees for licensing must be "sufficiently related to the statutory criteria" for issuing the
    license).
    Moreover, a test turning on the Court's own view of what expenses are strictly "necessary"
    to the maintenance of an otherwise authori.z ed program providing a private benefit would usurp
    for the Court a cost-estimating function that Congress textually committed, to some extent, to
    agency discretion. After all, the IOAA authorizes "[t]he head of each agency" to "prescribe
    regulations establishing the charge" of fees and lists the factors that agency heads are to consider
    in setting them. 
    31 U.S.C. § 9701
    (b); cf Cent. & S., 
    777 F.2d at 729
     ('-'Because Congress has
    expressly delegated to the ICC the responsibility for setting these fees, the ICC in exercising that
    authority is at the zenith of its powers; the ICC's fees, therefore, are entitled to more than mere
    deference or weight.") (internal quotation marks and citations omitted).
    On the other hand, the government's proposed "more than mere deference or weight"
    standard collapses important distinctions between quantitative and qualitative determinations and
    misstates the law in two ways.
    17
    First, an agency may not charge for an activity as part of an IOAA fee simply because that
    activity is lawful and "reasonably related" to an overall program, part of which provides a private
    benefit. The Circuit has held that "when the specific agency activity in question produces an
    independent public benefit, the agency must reduce the fee that it would otherwise charge by that
    portion of the agency's costs attributable to that public benefit." Cent. & S., 
    777 F.2d at 729
    (emphasis omitted). Thus, for example, in Elec. Indus. Ass 'n, the Circuit remanded to the Federal
    Communications Commission to reset or explain a fee that funded "94 percent of the annual
    budget" of its "Common Carrier Bureau" because "it strain[ ed] the limits of credulity" to believe
    that just "six percent of the work of that bureau had justifications independent of the services
    rendered to private parties." 554 F.2d at 1109. In other words, when calculating an IOAA fee to
    support a program that in part benefits private parties and in part independently benefits the agency
    and the public, the agency must disaggregate with respect to each charged-for activity the cost of
    providing the service to private beneficiaries from the cost of doing work that benefits the agency
    and the general public. So, in this case, it is not enough that an activity be generally PTIN-related
    and not invalidated by Loving. Rather, the government must be able to explain with respect to each
    activity that formed the basis for the PTIN fees how that activity was reasonably related to
    providing the private benefit that the Circuit identified in Montrois: a means of identifying return
    preparers that protects them from identity theft. As explained below, certain PTIN-related
    activities in fact provided an independent public benefit and thus should not have been charged for
    in full.
    Second, the government's blanket assertion that the agency's determination of fee amounts
    is due "more than mere deference or weight" blurs the lines between the type of activity performed
    and the cost of carrying out that activity. The government asserts flatly that "[w ]hen an agency
    18
    properly exercises its authority to charge a fee under the IOAA," the agency's "fee schedule is
    'entitled to more than mere deference or weight.'" Def.'s SJ. Mem. at 11 (quoting Cent. & S., 
    777 F.2d at 729
    ). To be sure, the Circuit has reasoned that the IOAA's commitment of fee-setting to
    agency discretion entitles the calculations themselves to significant deference. See Cent. & S., 
    777 F.2d at 729
    . But that is only a statement about the agency's discretion to calculate the amount of
    costs and benefits associated with a given activity, not whether a specific activity is sufficiently
    related to the provision of a private benefit. Determining whether an activity confers a private
    benefit, with or without also conferring an independent public benefit, is a matter of applying the
    IOAA, a statute that the IRS does not administer. And "[a] court does not defer to an agency's
    interpretation of a statute that it is not charged with administering." Del. Riverkeeper Network v.
    FERC, 
    857 F.3d 388
    ,396 (D.C. Cir. 2017). 8
    In sum, any challenge to an IOAA fee amount could potentially involve two separate
    inquiries, each of which requires a different level of deference to the agency. The first, and most
    relevant here, is whether, as a qualitative matter, the activities whose cost is used to justify the fee
    are reasonably related to the provision of the private benefit associated with the fee rather than an
    independent benefit to the agency and the public. The Court need not give any special deference
    to the agency in making that determination. But if the charged-for activities meet that qualitative
    bar, then the other inquiry is whether, as a quantitative matter, the amount charged for carrying
    them out is reasonable. And the agency's estimation of that amount is "more than mere deference
    or weight." Cent. & S., 
    777 F.2d at 729
    .
    8The government also suggests that compliance with Circular A-25 defmitively establishes that a fee amount is lawful
    under the IOAA. See Def.'s S.J. Mem. at 15 ("Here, the IRS complied with the directives ofOMB Circular A-25, and
    therefore, the PTIN user fee is reasonable under the IOAA."). But the Court need not reach that issue, because if an
    agency does not distinguish between "special benefits derived from Federal activities" and "those received by the
    general public," 0MB Circular A-25 § 6-the sole distinction at issue in this case-then it has not complied with
    Circular A-25.
    19
    In this case, that means that the Court will not defer to the IRS' s determination of whether
    the activities used to justify the PTIN and vendor fees were sufficiently related to the provision of
    PTINs to return preparers, but it will defer to the IRS's estimation of how much it costs to carry
    out those activities. With that standard in mind, the Court will consider each of the disputed fees
    in tum, considering first the FY 2011 through 2015 PTIN fees, followed by the FY 2016 and 2017
    PTIN fees, and concluding with the vendor fees for the entire period of FY 2011 through 2017.
    1. The FY 2011 through 2015 PTIN fees
    Plaintiffs argue that they are entitled to summary judgment holding that the FY 2011
    through 2015 PTIN fee of$50 was excessive to the extent that it was based on (1) compliance and
    suitability costs, which comprised most of the costs used to justify the fee; and (2) customer
    support, communication, IT, and operational support (together, "support") costs beyond certain
    limited subcategories. The government concedes much ground but maintains that it permissibly
    charged for certain limited activities in the first category and all activities in the second.
    As an initial matter, the parties disagree over which cost models to use in evaluating the
    alleged excessiveness of the fees. The government justifies a portion of the $50 fee for FY 2011
    through 2013 based on the IRS' s 2010 Cost Model and a larger portion of the same fee for FY
    2014 and 2015 based on the 2013 Cost Model. De£'s S.J. Mem. at 20-23. Plaintiffs argue that
    only the 2010 Cost Model is relevant to all five years. Pis.' Opp'n at 6-8. The Court agrees with
    plaintiffs that the government is wrong to rely on the 2013 Cost Model to differentiate FY 2011
    through 2013 from FY 2014 and 2015. Congress "expressly requir[ed] in the IOAA that fees be
    prescribed by regulation." New England Power Co. v. US. Nuclear Regulatory Comm 'n, 
    683 F.2d 12
    , 16 (1st Cir. 1982); see 
    31 U.S.C. § 9701
    (b). That requirement ensures "that such fees be
    communicated in advance to those who would have to bear them, thus permitting them to take
    20
    intelligent action to avoid undesired consequences." 
    Id.
     Whatever amount the IRS theoretically
    could have charged in FY 2014 and 2015 based on its internal 2013 Cost Model, it chose instead
    to charge the amount noticed by regulation as calculated in its 2010 Cost Model. The government
    cannot now avoid liability for any excessive fees charged in FY 2014 and 2015 based on activities
    for which it theoretically could have charged but actually did not. The Court will therefore evaluate
    the alleged excessiveness of the PTIN fees for all of FY 2011 through 2015 based on the
    justifications given in the 2010 Cost Model. 9
    (i) Compliance and suitability costs
    Plaintiffs argue that none of the RPO Compliance or Suitability Departments' activities
    were a valid basis for the FY 2011 through 2015 PTIN fees because those activities were
    invalidated by Loving. See Pls.' S.J. Mem. at 20-21. The government concedes that many costs
    related to suitability activities were an invalid basis for PTIN fees for that same reason, but it
    continues to defend compliance and suitability costs in four categories. See Def.'s Opp'n at 19-
    24. The Court agrees with plaintiffs in part and the government in part as to the Compliance
    Department and agrees with plaintiffs in full as to the Suitability Department.
    First, the government defends in full the IRS's decision to charge for the activities of the
    RPO Compliance Department, which "processes taxpayer complaints against return preparers,
    identifies return preparers who require enforcement, and conducts enforcement activities against
    return preparers who misuse or who do not use a PTIN." Def. 's Opp'n at 19-20. Specifically, the
    government asserts that the Compliance Department's activities include:
    (1) investigating "ghost preparers" (return preparers that do not list
    their PTINs on returns they prepared for compensation as required
    by law); (2) handling complaints from return preparers that a client's
    9
    That is not to say that the IRS may not use later cost models for assistance in calculating an eventual refund based
    on a more granular breakdown of the various RPO departments' activities. But in determining how much the IRS
    over-charged return preparers, the baseline must be the amount it actually charged in the first instance.
    21
    prior return preparer may have acted improperly by using a
    compromised PTIN or committed identity theft to obtain a PTIN;
    and (3) composing the data to refer complaint cases to IRS business
    units outside the RPO for further enforcement if necessary.
    Def.'s Opp'n at 19. According to the government, those activities are permissible bases for an
    IOAA fee because they "are reasonably related to the PTIN Program," which "advances the goals
    of protecting against identity theft recognized by Montrois as a special benefit justifying the PTIN
    user fee." 
    Id.
    As explained above, the government confuses the applicable standard by discussing
    whether these aptivities are reasonably related to the PTIN program overall rather than specifically
    to the associated private benefit of providing return preparers with a means of identification that
    protects their identity. Nevertheless, the Court agrees that the IRS permissibly charged for at least
    some of the three specific categories of Compliance Department activities that the government
    identifies. To the extent that they relate to misuse of PTINs, all three are reasonably related to the
    provision of the private benefit that the Circuit identified in Montrois-protection of preparers'
    identity-because the misuse of PTINs compromises their ability to serve as a secure means of
    identification. And tellingly, plaintiffs do not expressly dispute that much in their reply brief. See
    Pls.' Reply at 13-15, ECF No. 207-4.
    However, uncontroverted record evidence establishes that the Compliance Department
    undertook additional activities unrelated to the misuse or nonuse of PTINs. For example, the
    declaration of Diann Wensing, the former Director of RPO Compliance, which the government
    cites as giving a "more complete description" of the Compliance Department's work, DRPSUMF
    ,r 84, states that the Compliance Department's referral groups handled a broad swath of complaints,
    "includ[ing] theft of refund, preparer misconduct, RPO Program Noncompliance, Tax Preparation
    Noncompliance, ... TPPS Count Mismatch, etc." Wensing Deel.          ,r 161, Ex. BH to Oliver Deel.,
    22
    ECF No. 176-60. Wensing further states that the Compliance Department's Enforcement Planning
    & Direction Group undertook certain activities apparently unrelated to misuse ornonuse of PTINs,
    including "[ d]eveloping strategy recommendations for IRS Senior Management" to "Address
    Unregulated Return Preparer Conduct." 
    Id.
           ,r 208.   In short, it is apparent that some of the
    Compliance Department's activities concerned misconduct affecting return preparers' customers
    rather than the return preparers themselves. Those activities indisputably confer an independent
    public benefit, and thus their cost must be disaggregated from that of the three categories of
    preparer-benefitting activities identified above.
    Accordingly, the Court holds with respect to the Compliance Department that only the
    direct and indirect costs of (1) investigating ghost preparers; (2) handling complaints regarding
    improper use of a PTIN, use of a compromised PTIN, or use of a PTIN obtained through identity
    theft; and (3) composing the data to refer those specific types of complaints to other IRS business
    units were valid bases for the corresponding amount of the FY 2011 through 2015 PTIN fees.
    Second, the government defends the IRS's decision to charge for the Suitability
    Department's professional designation checks ("PDCs"), which "verify the self-reported
    credentials of CPAs and attorneys" working as return preparers. Def. 's Opp'n at 20-21. Plaintiffs
    argue that PDCs have nothing to do with the provision of a private benefit to return preparers
    because they "were designed to confirm credentials, not identities, and were performed at
    additional cost after PTIN applicants had received PTINs and had been identified." Pls.' Reply at
    10. The Court agrees with plaintiffs. The government provides no explanation whatsoever as to
    how verifying that an already-identified preparer's self-reported professional credentials are
    accurate is reasonably related to protecting that or any other preparer's identity. Instead, the
    government merely relies on "[t]he IRS['s] ... interest in verifying the identity of PTIN holders
    23
    and verifying this same identifying information is correctly displayed on [a] public facing website"
    that includes a directory of preparers. Defs.' Opp 'n at 21. That is an independent benefit to the
    agency and the public at large whose cost must be disaggregated from that of providing private
    benefits to return preparers. See Cent. & S., 
    777 F.2d at 729
    . Accordingly, the Court holds that the
    IRS unlawfully included the cost of PDCs in its calculation of the FY 2011 through 2015 PTIN
    fees.
    Third, the goven:iment defends the IRS's decision to charge for the Suitability
    Department's prisoner list checks and specially designated national ("SDN") checks, which
    determine whether an applicant is incarcerated or designated by the Treasury Department as being
    associated with certain targeted countries or illicit activities, respectively. See Def.' s Opp'n at 21-
    23. Plaintiffs argue that prisoner list and SDN checks provide no benefit to return preparers. See
    Pis.' Reply at 11. The Court agrees with plaintiffs. The government asserts that prisoner list and
    SDN checks help the Bureau of Prisons and Treasury Department to administer their own
    programs and that "[i]t is reasonable for the IRS to determine that the PTIN Program should be
    administered in compliance with, and without undermining, other important federal programs and
    regulations." Def.'s Opp'n at 22. Reasonable though that determination may be, it does not justify
    charging for prisoner list and SDN checks as part of the PTIN fee under the IOAA, because
    facilitating other agencies' operations is not reasonably related to the private benefit of protecting
    return preparers' identities. Again, that is an independent public benefit whose cost must be
    disaggregated from that of the private benefit to return preparers. See Cent. & s:, 
    777 F.2d at 729
    .
    Accordingly, the Court holds that the IRS unlawfully included the cost of prisoner list and SDN
    checks in its calculation of the FY 2011 through 2015 PTIN fees.
    24
    Fourth, the government defends the IRS's decision to charge for the Suitability
    Department's processing of suitability referrals by taxpayers or agency components of preparers
    who purportedly should not be able to obtain or maintain a PTIN-for example, because a
    preparers has been "legally enjoined from return preparation and from obtaining or renewing a
    PTIN." Def. 's Opp'n at 23-24. Plaintiffs point out that referrals also involved other complaints,
    such as "personal tax compliance," PDCs, and prisoner list and SON checks, and argue that "[t]he
    suitability checks and referrals, including referrals about enjoined preparers, were separate services
    undertaken to improve tax administration, benefit[t]ing only the IRS and the public." Pls.' Reply
    at 12. The Court agrees with plaintiffs. Suitability referrals were merely an intake system for the
    processing of Suitability Department inquiries that either the government no longer defends or the
    Court has just held provided no identifiable private benefit. Accordingly, the Court holds that the
    IRS unlawfully included the cost of suitability referrals in its calculation of the FY 2011 through
    2015 PTIN fees.
    (ii) Support costs
    The remainder of plaintiffs' motion with respect to the FY 2011 through 2015 PTIN fees
    challenges the IRS's decision to charge for certain RPO customer support, communication, IT,
    and operational support activities beyond those plaintiffs consider "necessary" to the provision of
    PTINs. See Pls.' S.J. Mem. at 20-25. In the corresponding portion of its cross-motion and its
    opposition, the government continues to defend a substantial portion of those costs. See Def. 's S.J.
    Mem. at 20-23; Def. 's Opp'n at 24-26. The Court cannot agree with either party in full.
    Rather than identify specific support costs as being insufficiently related to the provision
    of a private benefit, plaintiffs simply assert that the only "activities [that] were (and are) necessary
    to provide tax-return preparers a PTIN [are] (1) a small portion of customer support costs; (2) a
    25
    small portion of communication costs; (3) a small portion of IT costs; (4) a small portion of
    OPR/PMO Ops Support." Pls.' S.J. Mem. at 21 (internal quotation marks and citation omitted).
    Plaintiffs then explain why some specific costs in those categories were permissible bases for a
    fee under the IOAA but make no effort to explain why other support costs were not. The Court
    cannot simply accept plaintiffs' unexplained assurances that support costs beyond those on their
    list were not allowable.
    Still, it is undisputed that the IRS charged for support activities facilitating its entire pre-
    Loving return preparer regulatory apparatus. See 2010 Cost Model at 3 (listing such broad,
    department-wide support activities as "Programmatic Executive Management/Oversight" and
    "Operations Support"). Some of those support activities must have facilitated substantive activities
    that had nothing to do with protecting return preparers' identities, some of which were also
    invalidated by Loving. The portion of the support costs associated with those activities cannot be
    considered reasonably related to the provision of a private benefit and thus cannot form a valid
    part of the basis for an IOAA fee.
    While the government concedes some support costs included in the 2010 Cost Model, its
    concessions apparently do not reach all activities insufficiently related to the provision of a private
    benefit. As summarized in a declaration by current RPO Director Carol Campbell, those
    concessions do not include IT costs at all and only include communications and operational
    support costs "that are not PTIN-related." Second Carol Campbell Deel.          ,r 6,   ECF No. 203-1.
    Given the breadth of the RPO program before Loving and the 2010 Cost Model's failure to separate
    out the different work that the supporting departments were supporting, it is virtually certain that
    some RPO IT activities between FY 2011 and 2015 supported substantive activities invalidated by
    Loving. Furthermore, the government makes no attempt to estimate the portion of any RPO support
    26
    costs that went to providing the PTINs' associated identity-protecting benefit by issuing them and
    maintaining the PTIN database rather than other "PTIN-related activities" like PDCs which, as
    explained above, provided only an independent benefit to the agency and public. The government
    has not demonstrated that all of the support costs it continues to defend were reasonably related to
    the provision of a private benefit and therefore has not demonstrated its entitlement to partial
    summary judgment on that issue.
    Ultimately, the determination of which support costs were allowable must come down to
    the portion of those costs that went to support the provision of PTINs and maintenance of the PTIN
    database, and thus the conferral of the attendant private benefit of identity protection, rather than
    other RPO activities that were not PTIN-related or aspects of the PTIN program that conferred an
    independent public benefit, such as the Suitability Department activities discussed above. Only the
    former were valid bases for the FY 2011 through 2015 PTIN fees. As explained below, the agency
    will have an opportunity to determine what portion of support costs laid out in the 2010 Cost Model
    meet that bar on remand.
    2. The FY 2016 and 2017 PTIN fees
    The Court now turns to the PTIN fees for FY 2016 and 2017, which were set at $33 based
    on the 2015 Cost Model. Plaintiffs argue that those fees were excessive for the same reasons argued
    with respect to the FY 2011 through 2015 fees. See Pis.' S.J. Mem. at 25-27. The government
    makes essentially the same concessions it did with respect to those earlier fees-defending all
    compliance costs, certain suitability costs, and most support costs-and argues that it is entitled to
    partial summary judgment holding that a PTIN fee of $24 was permissible under the statute for
    FY 2016 and 2017. See Def. 's S.J. Mem. at 23-25.
    27
    Since the same activities remain in dispute with respect to the FY 2016 and 2017 PTJN
    fees as the FY 2011 through 2015 fees, the Court's holding as to each of those activities remains
    the same. First, allowable compliance costs include only the direct and indirect costs of (1)
    investigating ghost preparers; (2) handling complaints regarding improper use of a PTIN, use of a
    compromised PTIN, or use of a PTIN obtained through identity theft; and (3) composing the data
    to refer those specific types of complaints to other IRS business units. Second, it was unlawful for
    the IRS to charge for any suitability costs as part of the PTIN fees. Finally, it was only lawful for
    the IRS to charge PTIN users for support costs to the extent that they funded activities supporting
    the provision of PTINs, maintenance of the PTIN database, and in tum, the attendant priv_ate
    benefit rather than an independent benefit to the agency and public.
    The FY 2016 and 2017 PTIN fees do differ from the FY 2011 through 2015 PTIN fees in
    one relevant respect: They were determined based on the 2015 Cost Model. Thus, on remand to
    the agency, that later cost model will be the yardstick against which to measure which costs were
    actually allowable under the IOAA.
    3. The FY 2011 through 2017 vendor fees
    The Court will now consider the vendor fees that the IRS required PTIN users to pay
    Accenture from FY 2011 to 2017. As noted above, those fees were set at $14.25 for new PTIN
    registrations and $13 for PTIN renewals during FY 2011 through 2016 and $17 for both new
    registrations and renewals in FY 2017.
    As an initial matter, the Court will not consider plaintiffs' argument, raised for the first
    time in their reply brief, that the entire vendor fee was unlawful because it was not promulgated
    by regulation as required by the IOAA. See Pls.' Reply at 16-17. Whatever the merits of that
    argument, plaintiffs had every opportunity to include it in their opening summary judgment brief
    28
    but chose not to do so. "Arguments raised for the first time in a reply brief are waived." Nippon
    Shinyaku Co., Ltd. v. Iancu, 
    369 F. Supp. 3d 226
    ,239 n.8 (D.D.C. 2019).
    What is properly before the Court is plaintiffs' argument that the amount of the FY 2011
    through 2017 vendor fees was excessive under the IOAA. As with the PTIN fees themselves,
    plaintiffs argue that only the portion of the vendor fees "necessary to providing tax-return preparers
    a PTIN" were properly included in the PTIN fee. Pls.' S.J. Mem. at 19-20. The government
    defends the FY 2011 through 2017 vendor fees in full, arguing that they were set before Accenture
    updated the PTIN system to include capabilities invalidated by Loving. See Def.'s Opp'n at 27-
    29. 10 The Court agrees with plaintiffs in part.
    The government does not dispute that a significant portion of the vendor fees went to fund
    activities that had nothing to do with providing or maintaining PTINs and their attendant private
    benefit of identity protection to return preparers. For instance, the government admits that, at least
    in later releases, the PTIN system that Accenture designed and maintained had "the ability to ...
    determine preparer suitability based on tax compliance history successfully, ... process continuing
    education credit hours completed by calendar year, and perform case management," DRPSUMF
    ,r 52 (internal quotation marks and citation omitted), and that Accenture' s contract with the IRS
    required it to maintain a call center to address "preparer questions related" not only to "registration
    [and] renewal," but also to "testing, and [continuing education] processes and timelines," 
    id.
                         ,r 41
    (internal quotation marks and citation omitted). Those activities are not reasonably related to the
    10 The government also appears to argue in its opposition brief that plaintiffs lack standing to challenge the vendor fee
    because it was set by a contract to which they were not a party and thus may be challenged on[y in the Court of Federal
    Claims under the Administrative Dispute Resolution Act, and then only if they are "interested parties" within the
    meaning of that statute. See Def. ' s Opp'n at 27 (citing Emery Worldwide Airlines, Inc. v. United States, 
    264 F.3d 1071
    , 1079 (Fed. Cir. 2001)). However, the government concedes in the very next paragraph that "the only challenge
    Plaintiffs can raise in this proceeding is whether the product or service for which the IRS contracted is a direct or
    indirect cost of the PTIN Program that can be charged consistent with the IOAA and 0MB Circular A-25." Id. at 28
    (emphasis added). Plaintiffs only challenge the vendor fee as a user fee under the IOAA.
    29
    provision of a private benefit-rather, they provided an independent public benefit that was later
    invalidated by Loving.
    Nevertheless, the government argues that none of that matters, because the fees were
    initially set by contract in 2010, before many of those capabilities were implemented, and the
    initial release of the PTIN system only had the ability to issue, renew, and maintain PTINs. See
    Def.'s Opp'n at 28-29. That argument is unpersuasive. It is not as if the IRS and Accenture
    contracted for a more limited system and Accenture then just happened to expand its capabilities
    at a later date. The 2010 contract between the IRS and Accenture, which set the vendor fee amounts
    in effect during FY 2011 through 2016, expressly contemplated that Accenture would implement
    capabilities beyond the issuance, renewal, and maintenance of PTINs and would maintain a call
    center taking questions beyond those sub}ects. For example, the contract required Accenture to
    "develop and maintain a system capable of recording self-certification of continuing education
    reported by paid tax return preparers," including "capabilities to receive and electronically record
    test results," IRS-Accenture Contract (eff. Sept. 10, 2010) ,r 1, Ex. AA to Pis.' Mot. for S.J., ECF
    No. 177-9, and to implement support for "a tax compliance check prior to receiving a PTIN
    verifying that return preparers have no outstanding obligations on their personal or business federal
    tax returns" and a function "check[ing] to see if additional [continuing education] or test
    requirements are necessary," id.     ,r 2.2   (internal quotation marks omitted). It also required
    Accenture to "[d]evelop a service delivery program that address[ es] preparer questions related to"
    not only PTIN registration and renewal, but also continuing education and testing. Id.       ,r 3.   The
    vendor fees were calculated to compensate Accenture for developing and maintaining the entire
    expanded PTIN system, and the government cites no authority for the proposition that the Court
    should deem those fees not to include the costs of certain activities simply because those activities,
    30
    which were expressly contemplated by the contract from the very beginning, began some time
    after the contract became effective.
    Because the FY 2011 through 2017 vendor fees went beyond funding the portions of
    Accenture's work related to the issuance, renewal, and maintenance of PTINs and charged return
    preparers to cover portions of that work that benefitted only the agency and the public, those fees
    were excessive under the IOAA. The Court therefore holds that the IRS unlawfully required return
    preparers to pay whatever portion of the FY 2011 through 2017 vendor fees was attributable to
    activities unrelated to the issuance, renewal, and maintenance of PTINs and support for those
    activities. As explained below, the IRS will have an opportunity on remand to estimate that portion.
    B. The Government's Claimed Offset
    In its motion for partial summary judgment, the government argues that in the event it is
    found liable for some amount of restitution to the class, it is entitled to an offset in the amount of
    reasonable PTIN fees it could have charged return preparers, and vendor fees it would not have
    had to pay to Accenture itself, during FY 2018 through 2020 if not for this Court's 2017 injunction
    against the assessment of any PTIN fees, which the Circuit reversed. See Def.'s S.J. Mem. at 28-
    33. That argument is riddled with problems, and the Court cannot accept it.
    As a general rule, "[t]he right to recover what one has lost by the enforcement of a judgment
    subsequently reversed is well established." Baltimore & OR. Co. v. United States, 
    279 U.S. 781
    ,
    786 (1929). Accordingly, courts have recognized claims in restitution to "money[] paid pursuant
    to a court order that is subsequently reversed." Broadcom .Corp. v. Qualcomm Inc., 
    585 F. Supp. 2d 1187
    , 1189 (C.D. Cal. 2008). But this case presents a different scenario. The government does
    31
    not actually assert a counterclaim for restitution. I I Moreover, if it did so, it would be seeking
    restitution not for money the IRS paid to plaintiffs, but for the value of the IRS's uncompensated
    work of providing and maintaining their PTINs during the injunction period.
    The government cites no case in which a court has offset a plaintiffs eventual restitution
    award based on a sum that the defendant could have charged the plaintiff for its services but for a
    later-invalidated permanent injunction. The primary case that the government does cite, Williams
    v. Wash. Metro. Area Transit Comm 'n, 
    415 F.2d 922
     (D.C. Cir. 1968), involved an entirely
    different scenario. In that case, the Washington Metropolitan Area Transit Commission ("the
    Commission") issued an order raising transit fares that the Circuit later determined to be unlawful.
    Williams, 415 F.2d at 925-26. The Circuit ordered the Commission "to make restitution for all
    amounts collected as a consequence of the fare increas·e initially authorized by" the order, except
    for a certain amount of that increase "conceded" by the plaintiffs to have been lawful. Id. at 976.
    Williams is not analogous to this case for two reasons. First, the later-invalidated order at issue
    was not a court-ordered injunction, but an agency-ordered fare increase. Second, the Circuit
    reduced the amount of restitution not by an amount that the agency could have charged but was
    unable to, but an amount that the agency did charge and concededly was able to.
    Without any support on point, the government is asking the Court to approve a type of
    offset that is, to the Court's knowledge, entirely novel. That does not automatically make it
    impermissible-as the government correctly notes, the form of monetary relief plaintiffs seek is
    restitution, an equitable remedy whose amount the Court may reduce if equity so requires. See
    11
    Because the Court declines to order an offset for a variety of independent reasons, it need not consider plaintiffs'
    argument that the government was required to plead its claimed offset as a counterclaim rather than an affirmative
    defense. See Pls.' Opp'n at 20-21.
    
    32 Williams, 415
     F.2d at 943---45. But whatever the Court's authority to order an offset as an exercise
    of equitable discretion, it declines to do so in this case for several reasons.
    For one, the period for which the government seeks an offset actually extends past the
    vacatur of the injunction, into a period during which no order of this Court was stopping the IRS
    from assessing PTIN or vendor fees if it so desired. The Circuit's mandate vacating this Court's
    earlier judgment issued in March 2019, see ECF No. 98, and yet the government now seeks an
    offset for forgone fees extending all the way up to August 2020, when the IRS finally reinstated
    the PTIN and vendor fees, see Def. 's S.J. Mem. at 30-33. The government offers no explanation
    as to why the IRS did not attempt to assess PTIN or vendor fees in the intervening period of nearly
    a year and a half. If any offset due to the injunction were theoretically available, it would only be
    for the period during which the injunction was actually in effect: between July 2017 and March
    2019.
    Moreover, even narrowing the government's claimed offset to the relevant period, an offset
    to monetary relief requires the existence of mutual debts, which the government has not established
    here. "The right of setoff (also called 'offset' ) allows entities that owe each other money to apply
    their mutual debts against each other, thereby avoiding 'the absurdity of making A pay B when B
    owes A.'" Citizens Bank of Md. v. Strumpf, 
    516 U.S. 16
    , 19 (1995) (quoting Studley v. Boylston
    Nat. Bank, 
    229 U.S. 523
    , 528 (1913)). There are two problems with applying that principle in this
    case as the government requests. First, just because the government should have been able to
    charge PTIN and vendor fees during the relevant period, that does not necessarily mean that return
    preparers who registered or renewed during that period now owe the government the amount that
    it should have been able to charge. There is no evidence in the record that the IRS ever
    communicated to PTIN users during the relevant period that it intended to charge them a fee in the
    33
    event that the injunction was vacated, much less that it did so in accordance with the requirements
    of the IOAA, which would have been the basis for it to impose a financial obligation in exchange
    for the PTIN registrations and renewals. Second, there is a problem of mutuality: It appears that
    the class that the Court certified does not perfectly match up with the group of return preparers
    that the government now essentially asserts owes the IRS back-fees. As noted above, the Court
    certified a class of "[a]ll individuals and entities who have paid an initial and/or renewal fee for a
    PTIN, excluding Allen Buckley, Allen Buckley LLC, and Christopher Rizek." ECF No. 63. It is
    possible that some return preparers who paid a fee to obtain or renew a PTIN before the injunction
    did not renew that PTIN during the injunction period, and that some who obtained a PTIN for the
    first time during the injunction period did not subsequently renew that PTIN after the injunction
    was lifted and pay a fee. While the class-action form necessarily requires some rough justice in
    adjudicating the amount of monetary relief class members are due, what the government seeks
    here is essentially the adjudication of an alleged mutual debt that is not, in fact, mutual to every
    class member.
    Finally, an order approving the offset that the government seeks would have the effect of
    imposing (albeit retrospectively) a user fee, a task that the IOAA authorizes only "[t]he head of
    each agency" to carry out, and by "regulation[]" at that. 
    31 U.S.C. § 9701
     (b ). The Court is not the
    right entity, nor an order of restitution the right means, to assess under the statute a fee that was
    never formally set by the agency.
    For these reasons, the Court declines to fashion an equitable remedy for plaintiffs'
    restitution claim that offsets the IRS's liability by the amount of PTIN and vendor fees that it
    would have charged but could not, or did not, because of this Court's subsequently invalidated
    2017 injunction. To be clear, the Court expresses no opinion as to whether the IRS may claw back
    34
    the forgone PTIN and vendor fees through some other means, such as an administrative process
    setting fees retroactively for return preparers who registered or renewed their PTINs during the
    relevant period, or a civil action of its own for restitution. That question is beyond the scope of the
    present proceeding. 12
    C. The Information Requested on the PTIN Applications
    Finally, plaintiffs argue that the IRS lacks statutory authority to request any information on
    the PTIN application beyond the preparer' s "name, address, telephone number, social security
    number and date of birth," Pls.' S.J. Mem. at 27, and perhaps email address, 
    id.
     at 28 n.12, because
    that is the only information that "may be necessary to assign an identifying number," which is all
    the statute authorizes the IRS to require, 
    26 U.S.C. § 6109
    . However, while one factual allegation
    in the operative complaint hints at plaintiffs' belief that the IRS asks for more information than is
    necessary to provide a PTIN, see Second Am. Compl.                     ,r 20   ("For more than a decade, the IRS
    charged no fee to issue a PTIN and required tax return preparers to submit only their name, address,
    SSN (if applicable), and date of birth."), an express claim that the IRS exceeds its statutory
    authority under the PTIN statute by requesting further information is nowhere to be found in that
    complaint, see 
    id.
         ,r,r 43-59 (listing claims). 13 "New claims cannot be pled in summary judgment
    briefs." Cloud Foundation, Inc. v. Salazar, 
    999 F. Supp. 2d 117
    , 127 (D.D.C. 2013). That is just
    12
    The government also argues that plaintiffs previously asserted that an offset would be available and are now
    estopped from arguing to the contrary. See Def.' s Reply at 21. But in the pleading that the government cites, plaintiffs'
    opposition to the government's motion for a stay pending appeal, ECF No. 85, plaintiffs took no such position. Rather,
    plaintiffs argued that "if it prevailed on appeal, the government could attempt to recover the lo t fees through a
    restitution claim against PTIN holders." Id. at 19 (emphasis added) . That assertion contemplates a separate action or
    counterclaim, and besides, it says nothing of plaintiffs' view of the merits of such a claim.
    13
    In its prayer for relief, the operative complaint does request "[a] judgment declaring that the IRS may only request
    information from tax return preparers that is authorized by statute." Second Am. Comp!., Prayer for Relief ,i 5.
    However, even there, the complaint does not identify the authorizing statute or what specific requested information
    allegedly exceeds that authority. Thus, with respect to the appl ication questions, the operative complaint does not
    contain "a short and plain statement of the claim showing that the pleader is enti lled to relief' as any claim must. Fed.
    R. Civ. P. 8(a)(2).
    35
    what plaintiffs attempt to do here. The Court therefore will not entertain plaintiffs' argument about
    the IRS's statutory authority to request additional information on PTIN applications or their
    request for a declaratory judgment on that subject.
    D. The Appropriate Remedy
    As explained above, the PTIN and vendor fees for FY 2011 through 2017 were excessive
    to the extent that they were based on the following activities:
    •   All activities already conceded by the government in this
    case.
    •   Any Compliance Department activities other than (1)
    investigating ghost preparers; (2) handling complaints
    regarding improper use of a PTIN, use of a compromised
    PTIN, or use of a PTIN obtained through identity theft; and
    (3) composing the data to refer those specific types of
    complaints to other IRS business units.
    •   All Suitability Department activities.
    •   The portion of support activities that facilitated provision of
    an independent benefit to the agency and the public.
    •   The portion of Accenture's activities as a vendor that
    facilitated provision of an independent benefit to the agency
    and the public.
    But the scope of the compliance and support activities just identified is unclear from the record. It
    thus remains to be determined how that scope, and the corresponding cost amount, will be
    ascertained.
    The parties have not meaningfully briefed the appropriate course of action in the event
    that, following the Court's summary judgment decision, disputes remain as to the scope of the
    activities at issue and the cost of carrying out those activities. Plaintiffs assume that there will be
    a trial, at least on the amount ofrestitution. See Pls.' S.J. Mem. at 4 ("[P]laintiffs move only for an
    order granting summary judgment as to liability ... while reserving the amount of the excess fees
    36
    for trial."). The government, on the other hand, asserts for the first time in its reply brief that, "[i]n
    the unlikely event that the Court finds that the adjusted PTIN user fee is still unreasonable, remand
    is the appropriate remedy because neither the Court nor a party challenging the fee may seize the
    authority to develop the fee that has been granted to the agency by Congress." Def.' s Reply Supp.
    S.J. at 4-5. At any rate, the Court must now decide how this case will proceed following the
    adjudication of the cross-motions for summary judgment.
    This case cannot go to trial. Although the Court has permitted plaintiffs to seek the
    monetary remedy of restitution, this is still a case in which the Court is reviewing an agency
    action-the setting of IOAA fees, with an eye to whether those fees were excessive-under the
    AP A. 14 And in pushing for a trial on the extent to which the challenged fees were excessive,
    plaintiffs "misunderstand the role the district court plays when it reviews agency action. The
    district court sits as an appellate tribunal, not as a court authorized to determine in a trial-type
    proceeding whether" an agency determination was "factually flawed." Marshall County Health
    Care Auth. v. Shala/a, 
    988 F.2d 1221
    , 1225 (D.C. Cir. 1993).
    The only proper place for this case to go is back to the IRS. That is because,
    notwithstanding the reviewing court's authority to determine what activities an agency may
    lawfully charge for under the IOAA, that statute commits the amount to be charged to agency
    discretion. See 
    31 U.S.C. § 9701
    (b); Cent. & S., 
    777 F.2d at 729
    . Judges "do not sit as a board of
    auditors, steeped in accountancy and equipped to second-guess an estimate which seems on its
    face to be reasonable."

    excessive because it charged for unallowable activities, the extent and expense of which are in

    As explained in the Court's August 8, 2016 Memorandum Opinion, although the APA does not waive the United
    States's sovereign immunity with respect to money damages, it does in some cases waive sovereign immunity with
    respect to restitution of funds paid to the agency. See ECF No. 64 at 9-14 (citing America's Community Bankers v.
    FDIC, 
    200 F.3d 822
    , 830 (D.C. Cir. 2000)).

    dispute, the proper remedy is to remand to the agency to show its work and set a new fee within
    the bounds of what the law allows. See, e.g., Engine Mfrs. Ass 'n, 20 F .3d at 1184. To be sure, this
    is an unusual case in which the agency will be asked to do so retrospectively. But it would be
    anomalous to allow plaintiffs the opportunity to have a court set the fee and substitute its own
    judgment for the agency's simply because they waited until after they had paid the fee for several
    years to challenge it and seek monetary relief.
    Accordingly, the Court will remand to the IRS to determine an appropriate refund for the
    class that is consistent with this Opinion and the accompanying Order. Specifically, the Court will
    order the IRS to determine reasonable estimates of the portions it lawfully could have charged of
    the FY 2011 through 2015 PTIN fees based on the 2010 Cost Model, the FY 2016 and 2017 PTIN
    fees based on the 2015 Cost Model, and the FY 2011 through 2017 vendor fees based on the IRS-
    Accenture contracts. The Court will retain jurisdiction.
    IV.    CONCLUSION
    For the foregoing reasons, the Court will GRANT in part and DENY in part plaintiffs'
    motion for summary judgment and GRANT in part and DENY in part defendant's motion for
    partial summary judgment. The Court will issue a declaratory judgment holding that the PTIN and
    vendor fees for FY 2011 through 2017 were excessive to the extent that they were based on the
    following activities:
    •    All activities already conceded by the government in this
    case.
    •    Any Compliance Department activities other than (1)
    investigating ghost preparers· (2) handling complaints
    regarding improper use of a PTIN use of a compromised
    PTli'-J', or use of a PTIN obtained through identity theft· and
    (3) composing the data to refer those specific types of
    complaints to other IRS business units.
    •    All Suitability Department activities.
    38
    •   The portion of support activities that facilitated provision of
    an independent benefit to the agency and the public.
    •   The portion of Accenture's activities as a vendor that
    facilitated provision of an independent benefit to the agency
    and the public.
    Furthermore, the Court will remand to the IRS and order it to determine an appropriate refund by
    recalculating those fees, using the 2010 Cost Model as a benchmark for the FY 2011 through 2015
    PTIN fees and the 2015 Cost Model as a benchmark for the FY 2016 and 2017 PTIN fees, and
    excising a reasonable estimate of the portions of those fees that the Court has held unlawful. The
    Court will retain jurisdiction. A separate Order shall issue this date.
