    Appeal from the United States District Court

    Before SMITH, HAYNES, and GRAVES, Circuit Judges.
    JAMES E. GRAVES, JR., Circuit Judge:
    Billy and Ina White, John and Lynda Irvine, and Kenneth Kraemer1
    (collectively “Taxpayers”) assert that the Internal Revenue Service (“IRS”)
    erroneously assessed additional taxes and interest against them in connection
    with their investments in various partnerships in the 1980s. Taxpayers seek
    refunds of the federal income taxes and penalty interest paid. Taxpayers assert
    that the IRS’s assessment of additional taxes fell outside the applicable statute
    of limitations and that the IRS erroneously applied penalty interest. We hold

    Kraemer’s last name is spelled differently in different documents in this litigation.
    It is spelled as “Kraemer” in the case caption and in the original complaint, and as “Kramer”
    in Appellants’ briefing. In this opinion, we adopt the spelling in the case caption.

    that the district court lacked jurisdiction over the statute of limitations claims
    but did have jurisdiction over the penalty interest claims and that penalty
    interest was erroneously assessed.
    I. Factual and Procedural Background
    This tax refund suit is one among several arising from a series of limited
    partnerships managed by American Agri-Corp (“AMCOR”) in the 1980s. In an
    earlier AMCOR-related case, we explained the background:
    In the early 1980s, AMCOR organized a number of limited
    partnerships for which it acted as general partner. These
    partnerships had as stated goals acquiring agricultural land,
    investing in agricultural ventures, and growing crops. AMCOR
    solicited investments from high income professionals across the
    country. Each partner in an AMCOR partnership would receive a
    projected tax loss from crops planted in the first year of roughly
    twice that partner’s investment. Investors paid the farming
    expenses up front and deducted the amount invested on their tax
    returns. The next year, when the crops were harvested, the
    amount of loss in excess of the amount invested would be subject to
    taxes. However, the farming expenses typically exceeded any
    income realized from the farming activities. In 1987, the IRS began
    an investigation and audit into the AMCOR partnerships to
    determine whether they were impermissible tax shelters.
    Duffie v. United States, 
    600 F.3d 362
    , 367 (5th Cir. 2010) (footnote omitted); see
    also Weiner v. United States, 
    389 F.3d 152
    , 153 (5th Cir. 2004) (describing
    similar AMCOR partnerships).
    These Taxpayers were partners in AMCOR limited partnerships in the
    1980s. Billy White invested as a limited partner in Texas Farm Venturers in
    1984 and in Houston Farm Associates-II in 1985. John Irvine invested as a
    limited partner in Agri-Venture Fund in 1985.2 Kenneth Kraemer invested as

    Although Lynda Irvine and Ina White were not partners in the AMCOR partnerships,
    each of them filed a joint tax return with their husbands for each of the relevant tax years,
    thus becoming jointly and severally liable for the tax reportable on those returns. See 
    26 U.S.C. § 6013
    (d)(3).

    a limited partner in Rancho California Partners II in 1986. All Taxpayers
    reported their proportionate share of their respective partnerships’ losses in the
    relevant tax years.
    In 1990 and 1991, the IRS issued a Notice of Final Partnership
    Administrative Adjustment (“FPAA”) for the relevant tax years to the tax
    matters partners (“TMP”)3 of each of the partnerships. The FPAAs disallowed
    100% of each partnership’s farming expenses and other deductions. The FPAAs
    listed several reasons for disallowing the partnerships’ deductions, including,
    inter alia, IRS determinations that the partnerships engaged in a series of sham
    transactions, that the partnerships’ activities lacked economic substance, that
    the partnerships did not actually engage in farming activities, and that the
    partnerships had not substantiated their expenses.                The TMPs for the
    partnerships did not challenge the FPAAs but other partners filed Tax Court
    suits contesting each FPAA, including claiming that the FPAAs were untimely.
    All partners initially became parties to the partnership-level suits. See 
    26 U.S.C. § 6226
    (c). These Tax Court suits were eventually consolidated with
    other similar AMCOR-partnership cases and the Tax Court issued a decision
    determining that each FPAA issued to the partnerships was timely pursuant
    to 
    26 U.S.C. § 6229
    . See Agri-Cal Venture Associates v. Commissioner, 
    80 T.C.M. (CCH) 295
    , 
    2000 WL 1211147
    , at *16, *20, *22 (T.C. 2000). In July
    2001, a settled stipulated decision was entered in each Tax Court suit.
    In 1999 and 2000, during the pendency of the Tax Court suits and before
    the partnership-level stipulated settlements, the Whites, the Irvines and
    Kraemer individually settled with the IRS.             The settlement agreements
    disallowed only a portion of the farming deductions, as opposed to 100%

    “A tax matters partner is the partner designated to act as a liaison between the
    partnership and the IRS in administrative proceedings and as the representative of the
    partnership in judicial proceedings.” Duffie, 
    600 F.3d at
    366 n.1.

    disallowance.     After accepting Taxpayers’ settlements, the IRS assessed
    additional tax liability against each Taxpayer, including penalty interest under
    § 6621(c). Section 6621(c) imposed an interest rate of 120% of the statutory
    rate on “any substantial underpayment attributable to tax motivated
    transactions.” 
    26 U.S.C. § 6621
    (c) (1986).4 The IRS assessed additional tax of
    $14,397 and interest of $60,087.69 for the Whites’ 1984 tax year, and additional
    tax of $16,812 and interest of $59,295.34 for the Whites’ 1985 tax year. The
    Whites paid the additional taxes in February 2000 and filed an administrative
    claim for refund on February 12, 2002. The IRS assessed additional tax of
    $14,159 and interest of $52,459.64 for the Irvines’ 1985 tax year. The Irvines
    paid the additional taxes beginning in May 2000 and filed an administrative
    claim for refund on May 7, 2002. The IRS assessed additional tax of $9,817 and
    interest of $31,292.40 for Kraemer’s 1986 tax year. In February 2001, the IRS
    applied a previous deposit paid by Kraemer and issued Kraemer a refund;
    Kraemer filed an administrative claim for refund on February 11, 2003. The
    IRS did not act on any of Taxpayers’ claims for refund. In August 2008,
    Taxpayers filed this suit for refund of the taxes and interest.
    In their refund actions, the Whites and Irvines claimed that the
    additional taxes had been assessed after the statute of limitations for making
    such assessments had expired (“the statute of limitations claim”), and all
    Taxpayers claimed that the interest should not have been computed at the
    enhanced § 6621(c) penalty rate (“the penalty interest claim”). Taxpayers and
    the government moved for summary judgment. The district court granted
    summary judgment to the government on both claims, concluding that it lacked
    jurisdiction to consider the statute of limitations claim and that Taxpayers’
    4
    Section 6621(c) was repealed in 1989 but applies to the tax years in question. See

    claims for refund of penalty interest were untimely.          Taxpayers timely
    appealed.
    II. Statutory Background
    This case is governed by the Tax Equity and Fiscal Responsibility Act of
    1982 (“TEFRA”), generally codified at 
    26 U.S.C. §§ 6221-6233
    . See generally
    Weiner, 
    389 F.3d at 154-55
     (describing TEFRA’s provisions). TEFRA requires
    partnerships to file informational returns reflecting the partnership’s income,
    gains, deductions, and credits. 
    Id. at 154
    . Individual partners then report their
    proportionate share of the items on their own tax returns. 
    Id.
     “TEFRA requires
    the treatment of all partnership items to be determined at the partnership
    level.” 
    Id.
     (citing 
    26 U.S.C. § 6221
    ). “After TEFRA, the IRS could adjust
    partnership items at a singular proceeding, and then subsequently assess all
    of the partners based upon the adjustment to that particular item.” Duffie, 
    600 F.3d at 365
     (quotations omitted). “While TEFRA defines a ‘partnership item’
    in technical terms, the provision generally encompasses items ‘more
    appropriately determined at the partnership level than at the partner level.’”
    Weiner, 
    389 F.3d at 154
     (quoting § 6231(a)(3)). IRS regulations further clarify
    that “partnership item” includes “the accounting practices and the legal and
    factual determinations that underlie the determination of the amount, timing,
    and characterization of items of income, credit, gain, loss, deduction, etc.” 
    26 C.F.R. § 301.6231
    (a)(3)-1(b). A “nonpartnership item,” conversely, is an item
    that is not treated as a partnership item. 
    26 U.S.C. § 6231
    (a)(4). “The tax
    treatment of nonpartnership items requires partner-specific determinations
    that must be made at the individual partner level.” Duffie, 
    600 F.3d at 366
    .
    TEFRA also includes a third category of “affected items.” An “affected item” is
    “any item to the extent such item is affected by a partnership item.” 
    26 U.S.C. § 6231
    (a)(5); Duffie, 
    600 F.3d at 366
    . “Affected items can have both
    5
    Case: 12-20523   Document: 00512364111    Page: 6    Date Filed: 09/05/2013
    No. 12-20523
    partnership-item and nonpartnership-item components.” Duffie, 
    600 F.3d at 366
    .
    If the IRS adjusts any partnership items on a partnership’s informational
    income tax return, it must notify the individual partners by issuing an FPAA.
    
    26 U.S.C. § 6223
    ; see Duffie, 
    600 F.3d at 366
    . The partners have the right to
    challenge the FPAA in a partnership-level proceeding in the Tax Court, district
    court, or the Court of Federal Claims, according to specified procedures. 26
    U.S.C § 6226(a), (b); see Duffie, 
    600 F.3d at 366
    .         In a partnership-level
    proceeding, the court has jurisdiction to determine all partnership items for the
    tax year to which the FPAA relates, including the allocation of those items
    among the partners and the applicability of any penalty. 
    26 U.S.C. § 6226
    (f); see
    Duffie, 
    600 F.3d at 367
    . If a partner individually settles his or her partnership
    tax liability with the IRS, “the partner will no longer be able to participate in
    the partnership level litigation, and will be bound instead by the terms of the
    settlement agreement.” Weiner, 
    389 F.3d at 155
    .
    District courts generally have subject matter jurisdiction over an
    individual partner’s refund claim. 
    28 U.S.C. §§ 1340
    , 1346(a)(1); Weiner, 
    389 F.3d at 155
    . TEFRA, however, deprives refund courts of jurisdiction over claims
    “brought for a refund attributable to partnership items,” with limited
    exceptions. 
    26 U.S.C. § 7422
    (h). However, “a court does have jurisdiction in a
    partner-level refund action over partnership items that were converted to
    nonpartnership items through a settlement with the IRS.” Duffie, 
    600 F.3d at
    367 (citing 
    26 U.S.C. § 6231
    (b)(1)(C)).
    Against this statutory backdrop, we turn to the specific claims at issue.

    III. Discussion
    This court reviews a district court’s grant of summary judgment de novo
    and considers the same criteria that the district court relied upon when
    deciding the motion. Weiner, 
    389 F.3d at
    155-56 (citing Mongrue v. Monsanto
    Co., 
    249 F.3d 422
    , 428 (5th Cir. 2001)). Summary judgment is appropriate
    when “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). This court also
    reviews a district court’s determination of subject matter jurisdiction de novo.
    Calhoun County, Tex. v. United States, 
    132 F.3d 1100
    , 1103 (5th Cir. 1998).
    The parties do not assert that there are any disputed material facts on appeal.
    A.    The Statute of Limitations Claim
    The Whites and the Irvines first assert that the taxes and interest must
    be refunded because they were assessed by the IRS after the 
    26 U.S.C. §6501
    (a)
    statute of limitations had passed. Section 6501(a) is “the three-year statute of
    limitations which is generally applicable to the Commissioner’s assessment of
    tax.” Curr-Spec Partners, L.P. v. Comm’r of Internal Revenue, 
    579 F.3d 391
    , 395
    (5th Cir. 2009). Taxpayers argue that the IRS had no authority to assess
    additional tax and interest against them in 1999 and 2000 because the §
    6501(a) statute of limitations had run for the relevant tax years. They contend
    that 
    26 U.S.C. § 7422
    (h) does not bar jurisdiction because the § 6501(a) statute
    of limitations is a nonpartnership item based on the specific facts of each
    partner’s situation. The district court granted summary judgment to the
    government because it concluded that the statute of limitations involved the
    determination of a partnership item and it thus lacked jurisdiction under §
    7422(h).
    The dispositive question is whether the Whites’ and the Irvines’ claim
    that the additional tax assessments were time-barred is a claim for a refund
    7
    Case: 12-20523     Document: 00512364111        Page: 8   Date Filed: 09/05/2013
    No. 12-20523
    attributable to partnership or nonpartnership items.             “If the refund is
    attributable to partnership items, section 7422(h) applies and deprives the court
    of jurisdiction. If, on the other hand, the refund is attributable to
    nonpartnership items, then section 7422(h) is irrelevant, and the general grant
    of jurisdiction is effective.” Alexander v. United States, 
    44 F.3d 328
    , 331 (5th Cir.
    1995). This claim also involves the significant interplay between § 6501(a) and
    § 6229(a), a separate provision that can extend the § 6501(a) period for
    partnership items. See Curr-Spec Partners, 
    579 F.3d at 396
    . “For partnership
    items, the otherwise applicable limitations period of IRC § 6501(a) shall not
    expire before the date which is 3 years after the later of the date on which the
    partnership return was filed or the date on which it was due.” Curr-Spec
    Partners, 
    579 F.3d at 396
     (internal quotations and alterations omitted); 
    26 U.S.C. § 6229
    (a). Section 6229 can extend the tax assessment period in a variety
    of ways, such as when the TMP enters into an agreement with the IRS to extend
    the period, § 6229(b)(1)(B), fraudulent returns are filed, § 6229(c)(1) or the
    partnership fails to file a return, § 6229(c)(3).
    In Weiner, this court held that the § 6229 assessment period is a
    partnership item that cannot be raised in partner-level litigation. 
    389 F.3d at 157-58
    ; accord Keener v. United States, 
    551 F.3d 1358
    , 1363-64 (Fed. Cir. 2009).
    The Weiner court explained that because the § 6229 limitations issue “affects the
    partnership as a whole, it should not be litigated in an individual partner
    proceeding, as such a result would contravene the purposes of TEFRA.” Weiner,
    
    389 F.3d at 157
    . Taxpayers argue that they have not raised a § 6229 argument,
    but instead rely only on § 6501. However, all of Taxpayers’ attempts to
    distinguish Weiner ignore the fact that where a basis for a § 6229 extension is
    asserted, any limitations determination with regard to § 6501(a) must also
    8
    Case: 12-20523    Document: 00512364111     Page: 9    Date Filed: 09/05/2013
    No. 12-20523
    involve the resolution of § 6229, a partnership item. Where both are at issue,
    the § 6501 period cannot be separated from the § 6229 period.
    The Federal Circuit has issued a decision resolving this exact issue
    involving another AMCOR partnership with reasoning that we find logical and
    persuasive. See Prati v. United States, 
    603 F.3d 1301
    , 1307 (Fed. Cir. 2010). As
    the Prati court explained, “[s]ections 6501 and 6229 operate in tandem to
    provide a single limitations period. When an assessment of tax involves a
    partnership item or an affected item, section 6229 can extend the time period
    that the IRS otherwise has available under section 6501 to make that
    assessment.” 
    Id.
     (citing Andantech L.L.C. v. Comm’r, 
    331 F.3d 972
    , 976-77
    (D.C. Cir. 2003); Grapevine Imports, Ltd. v. United States, 
    71 Fed.Cl. 324
    , 328-
    39 (2006)). The Federal Circuit rejected the argument that a taxpayer could
    avoid the jurisdictional bar of § 7422(h) by raising a statute of limitations
    argument under § 6501 and failing to mention § 6229. Id. “Sections 6501 and
    6229 do not operate independently to allow a taxpayer to assert one in isolation
    and thereby render an otherwise timely assessment untimely.” Id.              An
    unpublished decision of this court has already expressed approval of this
    reasoning. See Matthews v. United States, Civ. No. 00-4131, 
    2010 WL 2305750
    (S.D. Tex. June 8, 2010), aff’d sub nom. Scott v. United States, 437 Fed. App’x
    281 (5th Cir. 2011) (“essentially” approving the district court’s opinion). We
    agree with the Federal Circuit that where the government asserts § 6229 as a
    basis to extend the § 6501(a) statute of limitations, the claim for refund is
    “attributable to” a partnership item and § 7422(h) bars consideration of the
    limitations claim. Prati, 
    603 F.3d at 1307
    ; Matthews, 
    2010 WL 2305750
    , at *4.
    Partners were required to raise the statute of limitations issue in the
    partnership-level proceeding prior to settlement and are barred from raising it
    in the refund action. See Prati, 
    603 F.3d at
    1307 & n.4.

    No. 12-20523
    Taxpayers argue that the IRS did not actually “assert” any basis for §
    6229 extensions of the § 6501 limitations period. This is incorrect. The
    government has asserted that § 6229(b)(1)(B) (extensions by agreement of the
    TMP), and § 6229(c)(3) (indefinite tolling if no valid partnership return is filed)
    provide a basis for extending the assessment periods for each of the relevant
    partnerships. Further, in the partnership-level proceedings, the Tax Court
    found that § 6229 had extended the assessment periods. See Agri-Cal Venture
    Associates, 
    80 T.C.M. (CCH) 295
    , 
    2000 WL 1211147
    , at *16, *20, *22.
    Taxpayers are correct that they are not bound by the Tax Court Agri-Cal
    decision because of their individual settlements. Thus, they argue that until
    the government actually proves these bases for an extension in the refund
    proceeding, jurisdiction is not barred. However, a refund court litigating or re-
    litigating a partnership item, such as the merits of the asserted § 6229 basis for
    an extension of the limitations period, is exactly the result prohibited by
    TEFRA. See Weiner, 
    389 F.3d at 158
    . Where a § 6229 basis for an extension is
    asserted, questions about whether the partnerships’ returns were fraudulent,
    contained substantial omissions, were never filed, or were subject to any
    extension agreements are matters to be determined at the partnership level
    under TEFRA’s statutory scheme.
    Taxpayers also argue that jurisdiction is not barred because the
    limitations issue was converted to a nonpartnership item in their settlement
    agreements. See Alexander, 
    44 F.3d at 331
    . Taxpayers’ argument here is
    foreclosed by Weiner. In Weiner, this court held that the assessment period was
    not converted to a nonpartnership item by the taxpayers’ settlement with the
    IRS where it was not specifically mentioned in the settlement. Weiner, 
    389 F.3d at
    156 n.2. As in Weiner, the settlement agreements here do not mention § 6229
    and thus the item was not converted by the settlement agreements. Id.

    Case: 12-20523     Document: 00512364111     Page: 11   Date Filed: 09/05/2013
    No. 12-20523
    In sum, because the § 6501 limitations period applicable to an individual
    partner cannot be determined without reference to the asserted bases for
    extensions under § 6229, which is a partnership item, the district court lacked
    jurisdiction over the statute of limitations claim under § 7422(h). We affirm the
    grant of summary judgment to the government on this claim.
    B.    The Penalty Interest Claims
    Taxpayers next challenge the penalty interest assessed against them
    under 
    26 U.S.C. § 6621
    (c). White and Irvine bring this claim in the alternative,
    while this is Kraemer’s only claim. Section 6621(c) imposed an interest rate of
    120% of the statutory rate on “any substantial underpayment attributable to
    tax motivated transactions.” 
    26 U.S.C. § 6621
    (c) (1986); see Duffie, 
    600 F.3d at 372-73
    . “The IRS may not assess interest under Section 6621(c) unless the
    substantial underpayment is attributable to one of the tax-motivated
    transactions defined by statute.” Duffie, 
    600 F.3d at 373
    . “Tax-motivated
    transactions include ‘any sham or fraudulent transaction,’ 
    26 U.S.C. § 6621
    (c)(3)(A)(v), and any use of an accounting method that may result in a
    substantial distortion of income, 
    26 U.S.C. § 6621
    (c)(3)(A)(iv).” 
    Id.
     Penalty
    interest is an affected item, made up of both partnership and non-partnership
    components. See Duffie, 
    600 F.3d at 378
    . The partnership component is
    whether the partnership’s transactions were tax motivated. See 
    id.
     The two
    non-partnership components of § 6621(c) interest are whether the individual
    taxpayer’s underpayment was (1) “substantial,” defined as being over $1,000,
    and (2) “attributable to” a tax-motivated transaction. See id. Under this rubric,
    a claim for refund based on a partnership component of § 6621(c) interest is
    jurisdictionally barred under § 7422(h), but a claim contesting one of the non-
    partnership items can be adjudicated by a refund court. Id.; see Weiner, 
    389 F.3d 11
    Case: 12-20523    Document: 00512364111      Page: 12   Date Filed: 09/05/2013
    No. 12-20523
    at 159-60 (determining whether the underpayment was “attributable to” a tax-
    motivated transaction).
    Taxpayers assert that § 6621(c) penalty interest cannot be imposed as a
    matter of law because there was no prior binding determination that any of the
    partnerships’ transactions were “tax motivated transactions.” The government
    again argues that the district court lacked jurisdiction to consider this issue
    because whether a partnership engaged in tax-motivated transactions is a
    partnership item, and that even if the court had jurisdiction, the claims for
    refund are computational adjustments governed by a shortened statute of
    limitations and were not timely filed.      After initially agreeing with the
    Taxpayers that the court had jurisdiction and that circuit precedent required
    refund of Taxpayers’ § 6621(c) interest, the district court reconsidered and
    granted summary judgment to the government on the grounds that the claims
    for refund were untimely.
    The government is correct that whether a partnership’s transaction is tax-
    motivated is a partnership item which a refund court does not have jurisdiction
    to determine. Duffie, 
    600 F.3d at 378-79
    . However, the question Taxpayers
    raise is different; they argue that no tax-motivated determination was actually
    made in an applicable partnership proceeding or in their settlements, and thus
    that there has been no tax-motivated transaction determination at all. The
    government relies on Duffie to essentially argue that the district court lacked
    jurisdiction even to determine whether a tax-motivated determination was
    made. Duffie does not support this conclusion. The Duffie court looked to the
    partnership-level merits decision in the Tax Court, which found that the
    partnership’s transactions were shams and lacked economic substance, and
    concluded that the determination was a sufficient finding that the transactions
    were tax-motivated and was binding on the unsettled partners seeking refunds.
    12
    Case: 12-20523    Document: 00512364111      Page: 13    Date Filed: 09/05/2013
    No. 12-20523
    
    600 F.3d at 378-80, 383
    . The court then explained that the Duffies’ claim was
    attributable to the Tax Court’s determination that the transactions were shams,
    and, “Because the nature of a partnership’s activities—whether they are sham
    transactions—is the partnership-item component of an affected item, the
    Duffies’ refund claim is based on the determination of a partnership item.” 
    Id. at 383
    . The court’s holding that it lacked jurisdiction over the refund claims
    clearly hinged on its finding that a sufficient tax-motivated transaction
    determination was already made at the partnership level. See 
    id.
    This situation is not like the one in Duffie. A refund court need not litigate
    the merits of any partnership item to decide whether the required tax-motivated
    determination has been made. See Duffie, 
    600 F.3d at 383
    ; Weiner, 
    389 F.3d at 162-63
    ; see also Bush v. United States, 
    717 F.3d 920
    , 928-29 (Fed. Cir. 2013)
    (explaining that whether a tax-motivated transaction was made in a previous
    partnership-level proceeding is a jurisdictional fact). The district court does not
    have jurisdiction to revisit whether a partnership’s transactions were actually
    tax-motivated, nor could the district court make that determination in the first
    instance.   However, the district court does have jurisdiction to determine
    whether such a finding has previously been made, either in the partnership-level
    proceedings or in a settlement. We thus find that § 7422(h) does not bar
    jurisdiction over Taxpayers’ claims that there was no tax-motivated
    determination supporting § 6621(c) penalty interest.
    Next, the government argues that even if the district court had
    jurisdiction, Taxpayers’ refund claims were not timely filed. Failure to timely
    file a refund claim deprives the court of subject matter jurisdiction for lack of
    a valid waiver of sovereign immunity. Duffie, 
    600 F.3d at 384
    . The regular
    deadline for filing a refund claim is two years from the date of payment or three
    years from the date of filing of a tax return, whichever is later. 
    26 U.S.C. § 6511
    (a); see Duffie, 
    600 F.3d at 385
    . Section 6230, however, supplants the
    13
    Case: 12-20523      Document: 00512364111        Page: 14     Date Filed: 09/05/2013
    No. 12-20523
    normal refund procedures and provides that for “[c]laims arising out of
    erroneous computations,” taxpayers have six months from the date of
    notification to bring a refund claim, rather than the normal two years. See 
    26 U.S.C. § 6230
    (a), (c)(2)(A).
    The question of whether the penalty interest refund claims were covered
    by the shortened deadlines in § 6230 is dependent on the question of whether the
    challenged adjustments including penalty interest are computational or
    substantive. See Duffie, 
    600 F.3d at 385
    . A computational adjustment to an
    individual partner’s tax liability can be made at the conclusion of the
    partnership level proceeding “without any factual determination at the partner
    level.” Duffie, 
    600 F.3d at 366
    ; see 
    26 U.S.C. § 6231
    (a)(6). A substantive affected
    item, however, requires “fact-finding particular to the individual partner” before
    any adjustment to tax liability can be made. Duffie, 
    600 F.3d at 366
    .
    Computational and substantive affected items each require different assessment
    procedures. 
    Id. at 385
    . For computational affected items, the IRS need not issue
    a statutory notice of deficiency, and § 6230 procedures and shortened time
    requirements apply. Id. By contrast, if the adjustment is a substantive affected
    item, the IRS must follow the normal deficiency procedures, including sending
    a notice of deficiency, and the normal § 6511(a) statute of limitations applies. Id.5
    Where, as here, Taxpayers’ refund claim is dependent on whether there
    was a sufficient tax-motivated transaction determination, and thus whether
    their underpayment was “attributable to” a tax-motivated transaction, see
    Weiner, 
    389 F.3d at 159-60
    , we find that § 6621(c) interest is a substantive
    affected item. This holding is supported by relevant case law. See Duffie, 
    600 F.3d at 386
     (analyzing whether penalty interest was computational in that case);
    5
    The IRS assessed additional taxes and penalties against Taxpayers by notice of
    computational adjustment rather than by sending a notice of deficiency. However, we reject
    any argument that the IRS’s chosen method of assessment is determinative.
    14
    Case: 12-20523      Document: 00512364111         Page: 15    Date Filed: 09/05/2013
    No. 12-20523
    see also Weiner, 
    389 F.3d at 159-62
     (analyzing whether an underpayment is
    “attributable to” disallowed deductions); McGann v. United States, 
    76 Fed. Cl. 745
    , 751, 754-59 (Fed. Cl. 2007). In Duffie, though ultimately determining that
    the adjustments at issue in that case were computational, this court first
    determined whether the Tax Court’s tax-motivated transaction determination
    was sufficient as a matter of law. Duffie, 
    600 F.3d at 378-80, 383
    . The Duffie
    court found that the tax-motivated transaction determination did not require a
    finding that an individual partner lacked a profit motive when engaging in the
    relevant transaction, and thus rejected the taxpayers’ argument that the tax-
    motivated transaction determination was insufficient. See Duffie, 
    600 F.3d at 378
    .   After making that determination, the “only issue” was whether the
    underpayment attributable to tax-motivated transactions was “substantial,” i.e.
    whether it was over $1,000; “clearly a computational rather than a substantive
    issue.” 
    600 F.3d at 386
    . Here, however, Taxpayers’ claims for refund assert that
    their underpayment was not attributable to any transaction found to be tax-
    motivated. This is a non-partnership component of § 6621(c) interest. See
    Duffie, 
    600 F.3d at 378
    . Further, answering this question requires analysis of
    substantive issues, including review and application of each individual partner’s
    settlement. See Weiner, 
    389 F.3d at 162-63
    . These claims require more than
    mere computations reflecting the treatment of partnership items. They are thus
    substantive and not computational, and Taxpayers claims are not governed by
    § 6230. We hold that Taxpayers’ claims for refund of penalty interest were
    timely filed.6
    Both parties agree that if the district court had jurisdiction over
    Taxpayers’ penalty interest claims and those claims were timely, Weiner dictates
    6
    Because we find that the claims were timely filed, we need not reach Taxpayers’
    additional argument that if § 6230 applies, the notices of computational adjustment sent by
    the IRS were not adequate to start the running of the statute of limitations.
    15
    Case: 12-20523     Document: 00512364111     Page: 16    Date Filed: 09/05/2013
    No. 12-20523
    that Taxpayers win on the merits of those claims. The FPAAs in Weiner listed
    several independent bases for disallowing the deductions, only some of which
    were tax-motivated transaction findings, the taxpayers settled and thus
    removed the need for a binding merits determination on any of the grounds for
    disallowance, and the settlements included no specific findings regarding the
    tax-motivated transaction issue. See Weiner, 
    389 F.3d at 162-63
    . The Weiner
    court found that in such a situation, “[t]here is no way, given the multiple
    reasons provided for the disallowance in the FPAAs, to determine whether the
    underpayments are ‘attributable to’ a tax motivated transaction.” 
    Id.
     The
    situation is identical here. Weiner thus dictates that the assessment of § 6621(c)
    penalty interest against Taxpayers was erroneous as a matter of law. Although
    other circuits have taken a different approach, see e.g., Keener, 
    551 F.3d at 1367
    ,
    Weiner is controlling in this circuit. We therefore reverse the grant of summary
    judgment to the government and render judgment in favor of Taxpayers on this
    issue.
    IV. Conclusion
    For the foregoing reasons, we AFFIRM the district court’s grant of
    summary judgment to the government on Taxpayers’ statute of limitations
    claims. We REVERSE the district court’s grant of summary judgment to the
    government and RENDER judgment in favor of Taxpayers’ on their penalty
    interest claims. We REMAND for any further necessary proceedings, such as
    whether there is any remaining issue regarding the amount to be refunded to
    Taxpayers.
