    Opinion of the Court
    OPINION
    Judge Jennifer B. Campbell delivered the opinion of the Court, in which
    Presiding Judge Brian Y. Furuya and Judge Paul J. McMurdie joined.
    C A M P B E L L, Judge:
    ¶1             The Ute Mountain Ute Tribe (Ute Mountain) and the
    Weeminuche Construction Authority (WCA) (collectively, the Appellants)
    challenge the tax court’s judgment upholding the Arizona Department of
    Revenue’s (the Department) determination that WCA owes transaction
    privilege taxes on its earnings from three construction projects. Because the
    gross proceeds from construction work performed under a contract with
    the federal government on a Native American reservation by a non-
    affiliated Native American contractor are subject to Arizona’s transaction
    privilege tax, we affirm the tax court’s judgment.
    BACKGROUND
    ¶2           Ute Mountain is a Native American tribe. Ute Mountain owns
    the WCA. In 2014 and 2015, the Bureau of Indian Affairs (the Bureau)
    contracted with WCA to perform three construction projects, two on the
    Navajo Nation and one on the Hopi reservation. Each project involved the
    management of reservation land resources and tribal water rights.
    ¶3            In 2018, the Department audited WCA from January 1, 2012
    through October 31, 2017. Upon completing the audit, the Department
    issued a deficiency assessment for transaction privilege taxes on WCA’s
    gross proceeds from the three construction projects (the project earnings),
    characterizing the projects as “for the B[ureau]” rather than “for” the
    Navajo and Hopi tribes. The Appellants protested the assessment, asserting
    the Bureau contracted with WCA in its trust capacity to benefit the Navajo
    and Hopi tribes, thereby exempting the project earnings from the
    transaction privilege tax.
    ¶4           Unable to resolve their dispute with the Department through
    informal and bypass conferences, the Appellants appealed to the tax court.
    On the Department’s motion, the tax court dismissed the Appellants’
    complaint with prejudice for failure to state a claim and denied the
    2
    UTE MOUNTAIN v. ADOR
    Opinion of the Court
    Appellants’ request to amend the complaint as untimely and futile. The
    Appellants timely appealed.
    DISCUSSION
    ¶5            Challenging the tax court’s dismissal of their complaint, the
    Appellants first argue that federal law preempts imposing Arizona’s
    transaction privilege tax in this case. Absent federal preemption, the
    Appellants alternatively contend that the project proceeds are exempt from
    Arizona’s transaction privilege tax under both TPR 95-11, the Department’s
    transaction privilege tax ruling in effect during the relevant period, and
    A.R.S. § 42-5122. Finally, the Appellants assert that the tax court improperly
    dismissed their claims without permitting them to file an amended
    complaint. We address each argument in turn.
    ¶6             Arizona law imposes an excise tax on persons and entities
    engaging in business within the State under certain business classifications.
    A.R.S. § 42-5008. Prime contracting is one of the enumerated business
    classifications subject to the transaction privilege tax. A.R.S. § 42-
    5010(A)(1)(h). Because the tax is “assessed on the privilege or right to
    engage in an occupation or business,” the business providing the service
    pays it and may not shift it to the customer.1 Vangilder v. Ariz. Dep’t of
    Revenue, 
    252 Ariz. 481
    , 485, ¶ 7 (2022).
    ¶7            We review the dismissal of a complaint de novo. Coleman v.
    City of Mesa, 
    230 Ariz. 352
    , 355, ¶ 7 (2012). We accept as true all well-pled
    factual allegations and reasonable inferences from them, Cullen v. Auto-
    Owners Ins. Co., 
    218 Ariz. 417
    , 419, ¶ 7 (2008), and will affirm only if, as a
    matter of law, the Appellants “would not be entitled to relief under any
    interpretation of the facts,” Coleman, 230 Ariz. at 356, ¶ 8 (quotation and
    citation omitted).
    I.     Federal Preemption
    ¶8           The Appellants contend that the tax court applied the wrong
    legal standard to assess whether federal law preempts imposing Arizona’s
    1      In their complaint, the Appellants alleged that “[t]he Department is
    foreclosed from enforcing its assessment” because “the Hopi Tribe and the
    Navajo Nation are indispensable parties that cannot be joined as a result of
    their sovereign immunity.” To the extent the Appellants reassert this
    contention on appeal, it lacks merit. An assessment for transaction privilege
    taxes is levied directly against the business and liability for such taxes may
    not be enforced against or passed onto the customer.
    3
    UTE MOUNTAIN v. ADOR
    Opinion of the Court
    transaction privilege tax on the project proceeds. Relying on White Mountain
    Apache Tribe v. Bracker, 
    448 U.S. 136
     (1980), the Appellants argue that the
    court should have engaged in a fact-specific inquiry and weighed the
    interests of the parties to determine whether federal law preempts
    Arizona’s taxing authority rather than finding the “bright-line” test for
    federal preemption enunciated in Arizona Department of Revenue v. Blaze
    Construction Co., Inc., 
    526 U.S. 32
     (1999), dispositive.
    ¶9            In Bracker, the United States Supreme Court considered the
    extent of state authority to regulate and tax economic activities on Native
    American reservations. 
    448 U.S. at 137
    . Recognizing Native American
    tribes’ “sovereignty over both their members and their territory,” the
    Supreme Court explained that “state law is generally inapplicable” to tribal
    conduct on reservations, but states may have a regulatory interest in the
    conduct of nontribal persons on reservations. 
    Id.
     at 142–44 (quotation and
    citation omitted). To assess the extent of a state’s interest, the Supreme
    Court formulated a balancing test requiring “a particularized inquiry into
    the nature of the state, federal, and tribal interests at stake.” 
    Id. at 145
    .
    ¶10            Applying this balancing test to the facts of the case, the
    Supreme Court held that the federal government’s “comprehensive”
    regulatory scheme for harvesting timber on Native American reservations
    was “so pervasive” that it precluded Arizona’s assessment of certain state
    taxes on the logging and hauling proceeds from a nontribal company’s
    contract with a Native American tribe to “fell[] tribal timber” and
    “transport[] it to the tribal organization’s sawmill.” 
    Id. at 136
    , 145–51.
    ¶11            Nearly 20 years later, in Blaze, the United States Supreme
    Court revisited the scope of state taxing authority over business conducted
    on tribal land and held that a state may impose taxes on the proceeds
    derived from a nontribal contractor’s federal contract for construction work
    on a Native American reservation. 
    526 U.S. at 34
    . Distinguishing Bracker,
    the Supreme Court held that applying a balancing test is proper only when
    the proceeds at issue derive from a nontribal entity’s direct transaction with
    the tribe or tribal members. 
    Id. at 37
    . Stated differently, the Supreme Court
    clarified that Bracker’s balancing test is inapplicable when a state seeks to
    tax a transaction between the federal government and a nontribal
    contractor. 
    Id.
     For economic transactions between the federal government
    and a nontribal contractor, the Supreme Court articulated a “bright-line
    standard” in favor of “tax[ing] federal contracts, regardless of whether the
    contracted-for activity takes place on [Native American] reservations.” 
    Id.
    4
    UTE MOUNTAIN v. ADOR
    Opinion of the Court
    ¶12            With that standard in mind, the Supreme Court considered
    the economic transaction at issue, involving a construction company owned
    by a Native American tribe member in Montana that contracted with the
    Bureau to build, repair, and improve roads on several Native American
    reservations in Arizona. 
    Id. at 34
    . Although Blaze was owned by a Native
    American and incorporated under the laws of the owner’s tribe, the
    Supreme Court deemed it “the equivalent of a non-[tribal entity] for
    purposes of th[e] case because none of its work occurred” on the owner’s
    tribal lands.2 
    Id.
     (citing Washington v. Confederated Tribes of Colville
    Reservation, 
    447 U.S. 134
    , 160–61 (1980) (“[N]onmembers are not
    constituents of the governing Tribe. For most practical purposes [non-
    affiliated Native Americans] stand on the same footing as non-[Native
    Americans].”)). At the end of the contracting period, the Department
    “issued a tax deficiency against Blaze for its failure to pay Arizona’s
    transaction privilege tax on the proceeds from its contracts with the
    Bureau.” 
    Id.
     The Supreme Court upheld the deficiency tax assessment,
    expressly distinguishing earlier cases, including Bracker, that applied a
    balancing test. 
    Id.
     at 37–39. In so doing, the Supreme Court explained that
    it “never employed [a] balancing test in a case” in which a state sought “to
    tax a transaction between the Federal Government and its non-[tribal]
    private contractor.” Id. at 37. Concluding “[i]nterest balancing in this setting
    would only cloud the clear rule,” and “to avoid litigation and to ensure
    efficient tax administration,” the Supreme Court adopted the “bright-line
    standard for taxation of federal contracts.” Id.
    ¶13           To support their contention that Bracker’s fact-specific inquiry
    and balancing test governs federal preemption here, the Appellants
    distinguish Blaze as simply a “governmental tax immunity case.” While the
    Supreme Court addressed the governmental tax immunity doctrine in Blaze
    and reaffirmed its previous holding that tax immunity applies only to the
    2       To the extent the Appellants contend that WCA enjoys sovereign
    immunity for its conduct on the Navajo Nation and Hopi reservation
    because it is wholly owned by a federally recognized Native American
    tribe, their claim lacks merit. Duro v. Reina, 
    495 U.S. 676
    , 686 (1990)
    (“Exemption from state taxation for residents of a reservation . . . is
    determined by tribal membership, not by reference to [Native Americans]
    as a general class.”), superseded on other grounds by statute as recognized in
    United States v. Lara, 
    541 U.S. 193
    , 196, 199–200 (2004); see also Ariz. Dep’t of
    Revenue v. Dillon, 
    170 Ariz. 560
    , 565–66 (App. 1991) (concluding taxpayer’s
    status as a Native American did not immunize him from Arizona’s taxing
    authority over economic transactions he conducted on another tribe’s
    lands).
    5
    UTE MOUNTAIN v. ADOR
    Opinion of the Court
    federal government or an “agency or instrumentality” closely connected to
    the federal government, the Appellants’ characterization fails to recognize
    the full scope of Blaze’s holding. 
    Id.
     at 35–36. Upon determining that Blaze
    did not qualify for, or even assert, governmental tax immunity, the Supreme
    Court considered Blaze’s contention that Arizona’s transaction privilege tax
    “cannot be applied to activities taking place on [Native American]
    reservations.” 
    Id.
     at 36–37. The Supreme Court acknowledged that its prior
    “cases involving taxation of on-reservation activity” had applied a
    balancing test but clarified that it had “never employed this balancing test”
    when a state sought “to tax a transaction” between the federal government
    and a nontribal private contractor. Id. at 37. Read in its entirety, the scope
    of Blaze’s holding is not, as the Appellants contend, limited to the
    governmental tax immunity doctrine.
    ¶14            The Appellants also argue that Blaze is inapplicable here
    because the Bureau, in contracting with WCA, was not “acting in the
    interest of the federal government” but “as and for” the Navajo and Hopi
    tribes. As such, the Appellants assert that there is no meaningful distinction
    between these facts and those of a “direct contractor-to-tribe arrangement,”
    unquestionably governed by Bracker’s balancing test. Moreover, the
    Appellants contend that Blaze is distinguishable because unlike the
    construction projects at issue in that case, which involved building and
    repairing “federal roads open to the general public,” here, the construction
    projects conserve and manage tribal resources. Furthermore, while nothing
    in Blaze’s factual recitation reflects that the tribes upon whose lands the
    roads were constructed took an active role in the projects, according to the
    Appellants, the Hopi and Navajo tribes were actively involved here.
    ¶15            Contrary to the Appellants’ contentions, Blaze expressly and
    unambiguously sets out a bright-line standard upholding state taxing
    authority over the proceeds derived from all federal contracts. Id. at 38. As
    the Appellants correctly note, the Supreme Court, in Blaze, did not fully
    analyze the extent of the tribes’ involvement with the federal public road
    projects on their lands. But, a bright-line test, by its nature, is not a nuanced,
    fact-specific inquiry. While pronouncing the bright-line rule, the Supreme
    Court acknowledged that tribes may choose “to advance their interests”
    under the Indian Self-Determination and Education Assistance Act by
    “enter[ing] into a self-determination contract ‘to plan, conduct, and
    administer programs or portions thereof, including construction
    programs.’” Id. (quoting 25 U.S.C. § 450f(a)(1)). Because the tribes “on
    whose reservations Blaze’s work was performed” did not “exercise[] this
    option, and the Federal Government [] retained contracting responsibility,”
    the Supreme Court determined it was unnecessary to consider whether the
    6
    UTE MOUNTAIN v. ADOR
    Opinion of the Court
    preemption doctrine “would apply when [t]ribes choose to take a more
    direct and active role in administering [] federal funds.” Id. at 38–39 (emphasis
    added).
    ¶16            Like Blaze, here, the Navajo and Hopi tribes did not enter into
    self-determination contracts to plan, conduct, and administer their own
    construction programs. Because the federal government retained
    contracting responsibility, the bright-line standard favoring taxation of
    federal contracts applies. Indeed, as this court has recognized, Blaze
    conclusively “resolved” that a state may tax the “proceeds from a contract
    with the federal government for work performed on [a Native American]
    reservation for the benefit of [Native Americans].” Luther Constr. Co., Inc. v.
    Ariz. Dep’t of Revenue, 
    205 Ariz. 602
    , 607, ¶ 28 (App. 2003). For that reason,
    the tax court correctly determined that federal law does not preempt
    Arizona’s transaction privilege tax in this case, and the Appellants’
    allegation predicated on federal preemption failed to state a claim for relief
    as a matter of law.
    II.     State Exemption
    ¶17           As the Appellants correctly note, Blaze does not mandate state
    taxation of federal contract proceeds but simply holds that federal law does
    not preempt state taxing authority over contracts negotiated between the
    federal government and nontribal contractors. 
    526 U.S. at 38
    . Absent federal
    preemption, the Appellants alternatively argue that the project proceeds are
    exempt from Arizona’s transaction privilege tax under both TPR 95-11 and
    A.R.S. § 42-5122.3
    ¶18            “Exemptions from the transaction privilege tax must be
    strictly construed, with the presumption being against such exemption.”
    Carter Oil Co., Inc. v. Ariz. Dep’t of Revenue, 
    248 Ariz. 339
    , 341, ¶ 5 (App. 2020)
    (internal quotation and citation omitted). In 1995, the Department issued
    TPR 95-11, which interprets Arizona’s transaction privilege tax statutes and
    specifically addresses “[t]he imposition of transaction privilege tax on
    activities performed on [Native American] reservations located within the
    State of Arizona.” We need not construe the Department’s ruling, however,
    to evaluate whether the Appellants adequately stated a claim for relief
    3      To the extent the Appellants reframe their reliance on TPR 95-11 as
    supporting a claim for administrative relief rather than an exemption, we
    note that the allegations of their complaint characterized the claim as one
    of exemption. Accordingly, we address the claim as raised in the tax court,
    not as recast on appeal.
    7
    UTE MOUNTAIN v. ADOR
    Opinion of the Court
    based on a TPR 95-11 exemption because the Department lacks the
    authority to create such an exemption. See State ex rel. Woods v. Block, 
    189 Ariz. 269
    , 275 (1997) (“The legislature has the exclusive power to declare
    what the law shall be.” (quotation and citation omitted)); Val-Pak East
    Valley, Inc. v. Ariz. Dep’t of Revenue, 
    229 Ariz. 164
    , 171, ¶ 27 n.8 (App. 2012)
    (explaining that the Department’s tax rulings are “advisory only” and “not
    controlling”). That is, the Department’s ruling cannot, as a matter of law,
    create a legal exemption to Arizona’s transaction privilege tax statutory
    scheme. Instead, TPR 95-11 provided only the Department’s interpretation
    of the relevant statutes, but those legal conclusions are not binding, and
    courts, not agencies, “remain the final authority on critical questions of
    statutory construction.” SWAT Training Facilities L.L.C. v. Ariz. Dep’t of
    Revenue, 
    251 Ariz. 269
    , 273, ¶ 8 (App. 2021). Indeed, TPR 95-11 includes an
    “explanatory notice” specifically stating that the ruling only “provide[s]
    interpretive guidance” and expressly acknowledging that it may be
    “modif[ied] or negate[d]” by statute, case law, administrative rules, or later
    rulings. To be clear, neither TPR 95-11 nor any other Department ruling
    created a legal exemption to Arizona’s transaction privilege tax statutory
    scheme.
    ¶19           Likewise, we need not construe A.R.S. § 42-5122 to evaluate
    whether the Appellants adequately stated a claim for relief predicated on a
    statutory exemption because the legislature did not enact A.R.S. § 42-5122
    until 2021, well after the relevant contractual period. See 2021 Ariz. Sess.
    Laws, ch. 443, § 4. To apply retroactively, a statute must contain an express
    statement of retroactive intent, and A.R.S. § 42-5122 contains no such
    language. A.R.S. § 1-244; see also Aranda v. Indus. Comm’n, 
    198 Ariz. 467
    , 470,
    ¶ 10 (2000). Moreover, even accepting the Appellants’ contention that
    A.R.S. § 42-5122 merely “codifie[d]” TPR 95-11, its enactment did not render
    the Department’s ruling a statutory exemption or otherwise imbue TPR 95-
    11 with legal force.
    ¶20            Because neither TPR 95-11 nor A.R.S. § 42-5122 provided an
    exemption, the project proceeds are subject to Arizona’s transaction
    privilege tax, and the Appellants’ allegations based on an exemption failed
    to state a claim for relief.
    III.   Estoppel
    ¶21          Having determined that federal law does not preempt
    Arizona’s taxing authority over the project proceeds and that neither TPR
    95-11 nor A.R.S. § 42-5122 exempts the project proceeds from Arizona’s
    transaction privilege tax, the remaining question is whether the tax court
    8
    UTE MOUNTAIN v. ADOR
    Opinion of the Court
    improperly denied the Appellants’ request to amend their complaint. Our
    review is constrained by the Appellants’ failure to submit proposed written
    amendments in the tax court. In their cursory written request, the
    Appellants broadly sought leave to amend without specificity, and at oral
    argument on the motion, they referenced only an amendment based on a
    claim of detrimental reliance on TPR 95-11.
    ¶22           As a rule, amendments should be liberally permitted absent a
    finding of undue delay, dilatory motive, undue prejudice, or futility in the
    amendment. Ariz. R. Civ. P. 15(a)(2) (“Leave to amend must be freely given
    when justice requires.”); Bishop v. State Dep’t of Corr., 
    172 Ariz. 472
    , 474–75
    (App. 1992); Owen v. Superior Court, 
    133 Ariz. 75
    , 79 (1982); see also
    Wigglesworth v. Mauldin, 
    195 Ariz. 432
    , 439, ¶ 26 (App. 1999) (explaining the
    court should grant a non-moving party the opportunity to amend a
    complaint “if such an amendment cures its defects”). “Although the
    superior court has the discretion to deny a motion to amend, we review de
    novo whether a request to amend is futile.” Worldwide Jet Charter, Inc. v.
    Toulatos, 1 CA-CV 21-0717, 1 CA-CV 22-0173, 
    2022 WL 17684985
    , at *4, ¶ 22
    (Ariz. App. Dec. 15, 2022). In considering futility, we presume as true all
    well-pled factual allegations outlined in the proposed amendments. See
    Cullen, 218 Ariz. at 419, ¶ 7.
    ¶23            A claim for “equitable estoppel may lie against a taxing
    authority under the following four circumstances: (1) the taxing authority
    engaged in affirmative conduct inconsistent with a position it later adopted
    that is adverse to the taxpayer, (2) the taxpayer actually and reasonably
    relied on the taxing authority’s prior conduct, (3) the taxing authority’s
    repudiation of its prior conduct caused the taxpayer to suffer a substantial
    detriment because the taxpayer changed its position in a way not compelled
    by law, and (4) applying estoppel against the taxing authority would
    neither unduly damage the public interest nor substantially and adversely
    affect the exercise of governmental powers.” Luther Constr. Co., 205 Ariz. at
    604–05, ¶ 11.
    ¶24           TPR 95-11 provided in relevant part:
    C. Construction contracts performed on [Native American]
    reservations.
    The gross proceeds derived from contracting activities
    performed on a reservation by the [Native American] tribe, a
    tribal entity or an affiliated [Native American] are not subject
    to Arizona’s transaction privilege tax.
    9
    UTE MOUNTAIN v. ADOR
    Opinion of the Court
    The gross proceeds derived from construction projects
    performed on [Native American] reservations by non-
    affiliated [Native American] or non-[Native American] prime
    contractors are not subject to the imposition of Arizona
    transaction privilege tax under the following conditions:
    1. The activity is performed for the tribe or a
    tribal entity for which the reservation was
    established; or
    2. The activity is performed for an individual
    [Native American] who is a member of the tribe
    for which the reservation was established.
    The gross proceeds derived from construction projects
    performed on [Native American] reservations by non-
    affiliated [Native American] and non-[Native American]
    prime contractors for all other persons, including the federal
    government, are subject to the imposition of Arizona
    transaction privilege tax.
    ¶25            In their reply brief, the Appellants contend for the first time
    that they reasonably believed the project proceeds were not subject to
    Arizona’s transaction privilege tax under Section I(C)—“The gross
    proceeds derived from contracting activities performed on a reservation by
    the [Native American] tribe, a tribal entity or an affiliated [Native
    American] are not subject to Arizona’s transaction privilege tax.”—because
    Ute Mountain is a tribe and WCA is a tribal entity. See In re Marriage of
    Pownall, 
    197 Ariz. 577
    , 583, ¶ 25 n.5 (App. 2000) (holding issues raised for
    the first time in a reply brief are waived). Waiver aside, this reading
    contradicts the plain language of the Department’s ruling, which states that
    activities performed on a reservation by “the” tribe, a tribal entity, or an
    affiliated Native American are exempt. Rather than encompassing any
    Native American tribe, tribal entity, or individual Native American, the
    ruling referred to “the” tribe, meaning the “tribe for whose benefit the
    reservation was established.” TPR 95-11, Definitions. Because neither Ute
    Mountain nor WCA are the intended beneficiaries of the Navajo or Hopi
    reservations, they are not contemplated within this provision.
    ¶26          Next, the Appellants assert that they reasonably believed the
    project proceeds were not subject to Arizona’s transaction privilege tax
    under Section I(C)(1)—“The activity is performed for the tribe or a tribal

    UTE MOUNTAIN v. ADOR
    Opinion of the Court
    performed its contracted services for the benefit of the Navajo and Hopi
    tribes. In other words, the Appellants contend that “for,” as the term is used
    in TPR 95-11, means the entity for whom the contracted work is intended to
    benefit rather than for whom the contractor contracted to work.
    ¶27            Viewed in isolation, the language of Section I(C)(1) arguably
    allows for the Appellants’ interpretation. Read within the context of the
    entire section, however, the Department expressly differentiated between
    contractor transactions with the tribe, a tribal entity, or an affiliated member
    and contractor transactions with a nontribal person or entity, “including the
    federal government.” To be clear, read as a whole, TPR 95-11 stated that
    project proceeds are not subject to Arizona’s transaction privilege tax when
    the entity for whom the contract is performed is “the tribe or a tribal entity.”
    Because TPR 95-11, in proper context, does not lend itself to the Appellants’
    proposed reading, there is no basis to conclude that the Department, in
    issuing the ruling, engaged in affirmative conduct inconsistent with its later
    deficiency tax assessment in this case or that the Appellants actually and
    reasonably relied on TPR 95-11 to conclude that the project proceeds are not
    subject to Arizona’s transaction privilege tax. Moreover, by the time WCA
    entered the contracts at issue, caselaw had addressed the scope of TPR 95-
    11 and clarified that Arizona’s transaction privilege tax “applie[s] to
    proceeds from federal contracts with non-[tribal members] to construct on-
    reservation structures for use by [tribal members].” Luther Constr. Co., 205
    Ariz. at 609, ¶ 34 (emphasis added); see also Ariz. Gen. Tax P. GTP 96-1
    (explaining that taxpayers “may rely” on a Department ruling “unless it has
    been revoked or modified” by legislation, administrative rules, court
    decisions, or subsequent Department rulings).
    ¶28           Because the proposed amended complaint—adding a claim
    relying on estoppel—nonetheless would have faced dismissal for failure to
    state a claim, the tax court did not abuse its discretion by denying the
    Appellants’ request to amend their complaint as futile. For these reasons,
    the tax court did not err by dismissing the Appellants’ complaint with
    prejudice.
