    This case comes to this Court on direct appeal from the
    Nineteenth Judicial District Court of East Baton Rouge Parish
    pursuant to Louisiana Constitution Article V, § 5(D)       upon a
    declaration by that court that 2015 La. Acts No. 109 (“Act 109”),
    which amended La.R.S. 47:33, is unconstitutional. Plaintiffs,
    Ivan   I.  Smith,   Jr.    and Gloria   G.   Smith  (collectively
    “Taxpayers”), are Louisiana residents and part owners of several
    limited liability companies (“LLC”) and Subchapter S corporations
    (“S corporation”) that transact business in Texas, Arkansas, and
    Louisiana.   Defendant herein is Kimberly L. Robinson, in her
    capacity as Secretary of the Department of Revenue of the State
    of Louisiana (the “Department”).     Taxpayers filed the instant
    suit seeking recovery of income taxes paid under protest.      At
    issue is whether Act 109, which amended La.R.S. 47:33, a state
    income tax statute that provides a credit to taxpayers for income
    taxes paid in other states, violates the dormant Commerce Clause
    of the United States Constitution. For the reasons herein set
    forth, we conclude that Act 109, which amended La.R.S. 47:33,
    violates the dormant Commerce Clause of the United States
    Constitution. Consequently, the judgment of the district court is
    hereby affirmed.

    Constitution. Consequently, the judgment of the district court is hereby affirmed.
    FACTS AND PROCEDURAL HISTORY
    Taxpayers own an interest in several LLCs and S corporations (the “Pass-
    Through Entities”) that transact business in Texas, Arkansas, and Louisiana.
    Taxpayers, Louisiana residents, paid 2015 Texas franchise taxes in the amount of
    $23,180.00, representing the amount of taxes based on the Pass-Through Entities’
    Texas-sourced income. Taxpayers were also subject to the Louisiana income tax on
    all of the income they derived both outside and inside Louisiana. The Department
    denied Taxpayers the credit they claimed against their 2015 Louisiana income tax
    for the franchise taxes they paid to the state of Texas; thus, Taxpayers paid
    $23,180.00, the amount of credit against Louisiana income tax to which Taxpayers
    would have been entitled absent Act 109, under protest, and then filed a Petition for
    Refund of Tax Paid Under Protest.3 The subject of the protest is the disallowance
    of the credit for taxes paid to Texas as a result of Act 109.
    In the Petition for Refund of Tax Paid under Protest, Taxpayers alleged that
    Act 109 limits the availability of credits for income taxes paid to other states.
    Pursuant to Act 109, credits are only available for income taxes paid to a state that
    3
    Louisiana Revised Statutes 47:1576(A)(1)(a) provides:
    Except as otherwise provided in Subsection B of this Section, any taxpayer
    protesting the payment of any amount found due by the secretary of the Department
    of Revenue, or the enforcement of any provision of the tax laws in relation thereto,
    shall remit to the Department of Revenue the amount due and at that time shall give
    notice of intention to either file suit or file a petition with the Board of Tax Appeals
    for purposes of recovery of such tax.
    2
    offers a reciprocal credit to that state’s own residents who transact business in
    Louisiana. Texas does not offer such a credit; thus, Act 109 denies a credit to
    Louisiana residents who transact business in Texas. Taxpayers asserted in the
    district court that the reciprocal credit requirement of Act 109 is unconstitutional as
    it violates the dormant Commerce Clause by subjecting them to multiple taxation.
    Taxpayers prayed that Act 109 be declared unconstitutional and that the taxes paid
    in accordance with Act 109 be refunded with interest as provided by law.
    In the district court, Taxpayers filed a Motion for Summary Judgment on the
    issue of the unconstitutionality of Act 109 and their entitlement to a refund of the
    taxes paid under protest. Taxpayers argued that Act 109 is unconstitutional because
    the Texas franchise tax imposes a tax on income, and Taxpayers would be entitled
    to a credit for the amount of Texas franchise taxes paid absent Act 109. Additionally,
    because Act 109 levels a double tax on interstate income, but not intrastate income,
    it violates the dormant Commerce Clause.
    The Department opposed Taxpayers’ Motion for Summary Judgment, arguing
    that the Texas franchise tax is not a tax on net income because it contains both a net
    income component and a net capital component, which are not divisible. Relative
    to the dormant Commerce Clause, the Department denied that Act 109 burdens
    interstate commerce because it is within the state’s power to regulate state income
    tax.
    Following a hearing, the district court reasoned that the First Circuit Court of
    Appeal in Perez v. Secretary of Louisiana Department of Revenue & Taxation, 98-
    330 (La.App. 1 Cir. 3/8/99), 
    731 So.2d 406
    , writ denied, 99-951 (La. 6/4/99), 
    743 So.2d 1256
    , had already addressed and affirmatively concluded that the Texas
    franchise tax was an income tax under Louisiana law; thus, it was settled law and
    binding on the court. Further, the district court concluded that the United States
    3
    Supreme Court decision in Comptroller of Treasury of Maryland v. Wynne, 
    135 S.Ct. 1787
     (2015), was dispositive of the constitutional issue raised. The district court
    found the resolution to be “straightforward,” given the holdings of Perez and Wynne.
    For these reasons, the district court granted Taxpayers’ Motion for Summary
    Judgment, declared Act 109 unconstitutional, and rendered judgment in favor of
    Taxpayers for $23,180.00, plus interest as provided by law.
    The Department, pursuant to Louisiana Constitution Article V, § 5(D),
    directly and suspensively appealed the district court judgment to this Court.
    LAW AND ANALYSIS
    Act 109
    Prior to 2015, a Louisiana taxpayer who derived income from another state,
    and who paid net income taxes on that income in that other state, received a full
    credit for the payment of out-of-state taxes pursuant to La.R.S. 47:33. Prior to 2015,
    La.R.S. 47:33 provided in pertinent part:
    A. Subject to the following conditions, resident individuals shall be
    allowed a credit against the taxes imposed by this Chapter for net
    income taxes imposed by and paid to another state on income taxable
    under this Chapter, provided that:
    (1) The credit shall be allowed only for taxes paid to the other state on
    income which is taxable under its law irrespective of the residence or
    domicile of the recipient.
    In 2015, the Louisiana legislature adopted Act 109, which amended La.R.S.
    47:33. Act 109 amended La.R.S. 47:33(A)(4) through (6) to provide:
    A. Subject to the following conditions, resident individuals shall be
    allowed a credit against the taxes imposed by this Chapter for net
    income taxes imposed by and paid to another state on income taxable
    under this Chapter, provided that:
    ....
    (4) The credit shall be allowed only if the other state provides a similar
    credit for Louisiana income taxes paid on income derived from property
    4
    located in, or from services rendered in, or from business transacted in
    Louisiana.
    (5) The credit shall be limited to the amount of Louisiana income tax
    that would have been imposed if the income earned in the other state
    had been earned in Louisiana.
    (6) The credit shall not be allowed for income taxes paid to a state that
    allows a nonresident a credit against the income taxes imposed by that
    state for taxes paid or payable to the state of residence.
    As a result of the 2015 amendment to La.R.S. 47:33, 4 a Louisiana taxpayer is
    allowed to take a credit for out-of-state taxes paid on income earned out of state only
    if that other state’s tax laws provide a reciprocal credit for residents of that state who
    earn income in Louisiana. Further, even if a reciprocal credit exists, the credit is
    limited to the amount the taxpayer would have paid in Louisiana taxes.
    Motion for Summary Judgment
    In this case, the district court’s ruling was pursuant to Taxpayers’ Motion for
    Summary Judgment. La.Code Civ.P. art. 966. Summary judgments are reviewed
    de novo on appeal, with the reviewing court using the same criteria that govern the
    trial court’s determination of whether summary judgment is appropriate; whether
    there is any genuine issue of material fact, and whether the movant is entitled to
    judgment as a matter of law. La.Code Civ.P. art. 966; Louisiana Safety Ass’n of
    Timbermen-Self Insurers Fund v. Louisiana Ins. Guar. Ass’n, 09-23, p. 5 (La.
    6/26/09), 
    17 So.3d 350
    , 353. In this case, there are no material issues of fact in
    dispute. We are called upon to interpret the law at issue. Questions of law are
    reviewed de novo, without any deference to the legal conclusions reached by the
    district court, as this court is the ultimate arbiter of the meaning of laws of this state.

    124 So.3d 1065
    ,
    1071).
    Louisiana Revised Statutes 47:33
    The initial inquiry is whether the Taxpayers’ payment of the Texas franchise
    tax is a “net income tax[] imposed by and paid to another state[,]” pursuant to La.R.S.
    47:33(A). As recognized by the district court, this precise issue was decided by the
    First Circuit Court of Appeal in the case of Perez, 
    731 So.2d 406
    , which held that
    Texas franchise tax paid by an S corporation is a net income tax paid by individual
    shareholders of the S corporation, and that such shareholders are entitled to a credit
    for the tax paid to Texas against their Louisiana tax liability.
    The taxpayers in Perez were Louisiana residents and sole shareholders of a
    Louisiana S corporation. The Perezes filed a Louisiana individual income tax return
    and claimed a credit under La.R.S. 47:33 for Texas franchise taxes paid by their
    S corporation to Texas. The Department denied their claim and argued that the credit
    is allowed only for net income taxes paid to another state and that the Texas franchise
    tax was not an income tax. The Department also argued that the credit was not
    allowed because the S corporation paid the tax, the Perezes did not. The court of
    appeal concluded that the Texas franchise tax, “to the extent it was imposed on an
    income base, is a net income tax imposed by and paid to another state on income
    also taxable under Louisiana’s income tax laws, as required for the application of
    [La.R.S.] 47:33.” Perez, 731 So.2d at 408-09. The court of appeal also held that
    “the fact that the Corporation paid the Texas tax does not prevent the tax from being
    available to an individual taxpayer for a credit pursuant to [La.R.S.] 47:33.” 
    Id. at 409
    .
    6
    Notably, the Department acquiesced in the Perez decision in its Statement of
    Acquiescence No. 03-001 issued September 10, 2003. Therein, the Department
    concluded that “[t]axes on net income paid by an S corporation shall be considered
    taxes on net income paid by shareholders of the S corporation for purposes of
    computing the credit allowed under [La.R.S.] 47:33.”5
    The Department now reverses its position and currently asserts that the Texas
    franchise tax is not an income tax pursuant to La.R.S. 47:33 and that the district court
    erred in relying on Perez and concluding to the contrary. First, the Department urges
    that the district court reached its erroneous conclusion by failing to recognize that
    the credit granted by La.R.S. 47:33 must be strictly construed against the
    Taxpayers. 6 The Department claims that not only did the Perez decision fail to
    adhere to the rule of strict construction, but it also failed to cite the Texas
    Constitution, which forbids the imposition of an income tax absent voter
    referendum. Moreover, the Department now rejects Perez, as that decision predates
    the revisions to the Texas franchise tax in 2006; therefore, it contends that Perez did
    not analyze La.R.S. 47:33 after its 2015 amendment in relation to the Texas franchise
    tax provisions after its 2006 revisions.
    5
    The Statement of Acquiescence contains the following language:
    A Statement of Acquiescence or Nonacquiescence (SA/SNA) is issued under the
    authority of LAC 61:III.101(C). It is a written statement to provide guidance to the
    public and to Department of Revenue employees. An SA/SNA is a written
    statement issued to announce the Department’s acceptance or rejection of specific
    unfavorable court or administrative decisions. If a decision covers several disputed
    issues, an SA/SNA may apply to just one issue, or more, as specified. An SA/SNA
    is not binding on the public, but is binding on the Department unless superceded by
    a later SA/SNA, declaratory ruling, rule, statute, or court case.
    6
    “[E]xemptions from taxation are to be strictly construed against the person claiming the
    exemption, and any plausible doubt is fatal, Mattingly v. Vial, 
    193 La. 1
    , 
    190 So. 313
     (1939), and
    that an exemption being an exceptional privilege, it must be clearly, unequivocally and
    affirmatively established. Meyers v. Flournoy, 
    209 La. 812
    , 
    25 So.2d 601
     (1946).” Ethyl Corp.
    v. Collector of Revenue, 
    351 So.2d 1290
    , 1293 (La.App. 1 Cir. 1977), writ denied, 
    353 So.2d 1035
    (La.1978).
    7
    The Department’s initial argument is that Taxpayers in this case are not
    entitled to claim the credit because, strictly construing La.R.S. 47:33(A), the Texas
    franchise taxes paid are not “net income taxes imposed by and paid to another
    state[.]” The Department argues that because it is not an income tax, Taxpayers are
    not entitled to the credit under the plain language of La.R.S. 47:33; thus, the district
    court erred in deciding the constitutionality issue. Instead, the Department maintains
    that this Court may resolve this matter solely on the basis that the Taxpayers do not
    qualify for the credit on statutory grounds.
    Since the Perez decision in 1999, which holding the Department acquiesced
    in since 2003, a Louisiana taxpayer who paid the Texas franchise tax on income
    derived from sources in Texas has been entitled to claim a credit for those taxes paid
    against its Louisiana tax liability. Indeed, even after Texas revised its franchise tax
    provisions, the Department did not revoke or modify its Statement of Acquiescence,
    and it made no change in its position relative to a taxpayer’s entitlement to a credit.
    The Department now reverses its longstanding position and asserts that the Texas
    franchise tax is not an income tax pursuant to La.R.S. 47:33. We find no merit in
    this contention.
    The Perez court correctly held that the Texas franchise tax is a tax on net
    income, applying the test established by this Court in City of New Orleans v.
    Scramuzza, 
    507 So.2d 215
     (La.1987).7 In Scramuzza, 507 So.2d at 218, this Court
    7
    At issue in Scramuzza was an earnings tax, which this Court found was an income tax because it
    operated to tax income. In Scramuzza, this Court reasoned that “[t]o ascertain a precise definition
    of an income tax would prove to be a near impossible task[,]” and that any “definition must
    necessarily vary to conform to the various systems of income taxation.” Scramuzza, 507 So.2d at
    218 (footnote omitted). This Court stated, therefore, that its task was not to provide a definition
    of income tax; instead, it merely had to determine if the earnings tax should be classified as an
    income tax. This Court recognized that an “[i]ncome tax . . . may be understood both technically
    and in more general terms[,]” and concluded that “[a]n income tax in most generally understood
    terms is a tax on income.” Id. at 218. This Court recently affirmed the Scramuzza test in Beer
    Industry League of Louisiana v. City of New Orleans, 18-280, 18-285, p. 10 (La. 6/27/18), 
    251 So.3d 380
    , 387.
    8
    held that the “[c]lassification of a tax must be determined by its operational effect
    rather than by the descriptive language used in drafting the enactment.” Perez
    recognized that “in classifying a tax[,] the operational and consequential effect of
    the tax must be given paramount consideration.” Perez, 731 So.2d at 408 (citing
    Scramuzza, 507 So.2d at 219). Pursuant to Scramuzza, the Perez court concluded
    that the “operational effect” of the Texas franchise tax was to tax the income of the
    corporation. Perez, 731 So.2d at 408.
    In considering the current version of the Texas franchise tax, the relevant
    inquiry remains whether the operational and consequential effect of the law is to
    impose a tax on income that is subject to the Louisiana income tax. Scramuzza, 
    507 So.2d 215
    . Therefore, we must examine the current version of the Texas franchise
    tax.8
    In its current form, the Texas franchise tax uses a three-step calculation to
    arrive at a “taxable margin.” Tex. Tax Code § 171.101. Step one of the calculation
    begins with a taxpayer’s gross receipts; from the gross receipts, the taxpayer deducts
    certain amounts for returns and other allowances. Tex. Tax Code §§ 171.101;
    171.1011. Secondly, the Texas tax code allows for additions or deductions to arrive
    at a “total revenue” figure. Tex. Tax Code §§ 171.101; 171.1011. The amount of
    “total revenue” is the figure used for the third step of the calculation. In the final
    step, the taxpayer uses one of four alternative methods to determine the “taxable
    margin”: (1) seventy percent of the “total revenue”; (2) “total revenue” minus
    $1,000,000.00; (3) “total revenue” minus wages; or, (4) “total revenue” minus cost
    of goods sold. Tex. Tax Code § 171.101. Once the “taxable margin” is derived, the
    8
    See In re Nestle USA, Inc., 
    387 S.W.3d 610
     (Tex.2012) (discussing the history of the Texas
    franchise tax on domestic and foreign corporations since 1893).
    9
    taxpayer then apportions that amount and takes other allowable deductions. Tex.
    Tax Code §§171.106; 171.107-09.
    Considering the manner in which the current Texas franchise tax is calculated,
    it is still essentially imposed on an income basis. The Perez court opined that “the
    Texas tax, to the extent it was imposed on an income base, is a net income tax
    imposed by and paid to another state on income also taxable under Louisiana’s
    income tax laws, as required for the application of [La.R.S.] 47:33.” Perez, 731
    So.2d at 408-09. The sole question, as espoused in Scramuzza, is whether the
    operational and consequential effect means that the tax can be fairly classified as a
    tax on net income. The Perez court correctly determined that it did, and we conclude
    that the revisions to the Texas franchise tax in 2006 did not change this result. The
    current version of the Texas franchise tax begins with revenue, applies the three-step
    calculation, and taxes income that is also taxable under Louisiana law. For these
    reasons, like the franchise tax prior to 2006, the Texas franchise tax post 2006 is a
    net income tax for purposes of La.R.S. 47:33.
    In addition to finding that the Texas franchise tax was a net income tax, Perez
    also addressed the fact that the payment of that tax was made by a pass-through
    entity doing business in Texas, but the credit was being claimed by individual
    shareholders of the S corporation stating:
    The Department contends that the credit cannot be given to the
    Perezes for a tax liability owed and paid by the Corporation. There is
    no statutory requirement that the tax be imposed on the individual
    shareholders of an “S” Corporation or that the shareholders have
    personal liability for the tax in order for the credit to be allowed.
    [La.R.S.] 47:33 does not require that the tax paid to the other state be
    imposed on or paid by the individual taxpayer. As long as a net income
    tax of another state is “paid” to that other state on income also taxable
    by Louisiana, a credit is allowed. Therefore, the fact that the
    Corporation paid the Texas tax does not prevent the tax from being
    available to an individual taxpayer for a credit pursuant to [La.R.S.]
    47:33.
    10
    Perez, 731 So.2d at 409. We agree and reiterate that the Department acquiesced in
    this holding stating in its Statement of Acquiescence No. 03-001 that “[t]axes on net
    income paid by an S corporation shall be considered taxes on net income paid by
    shareholders of the S corporation for purposes of computing the credit allowed under
    [La.R.S. 47:33].”
    At present, and reversing its position, the Department now urges that it is not
    plausible that the Texas franchise tax imposed upon the S corporation and the LLC
    can be characterized as a net income tax imposed upon Taxpayers individually.
    Because of the legal nature and manner of taxation of S corporations and LLCs, for
    the shareholders or members of these pass-through entities, the operational and
    consequential effect is a tax on the individual taxpayer. The pass-through entity does
    not pay a tax on its income. To the contrary, that income is distributed to the
    shareholders or members, and the shareholder or member individually pays income
    tax on the distributions. Therefore, we find no merit to the Department’s assertion
    that the requisite strict construction of the statute against Taxpayers results in the
    conclusion that it does not apply to a franchise tax imposed upon Taxpayers’ Pass-
    Through Entities.
    In its original brief to this Court, the Department relies on Graphic Packaging
    Corp. v. Hegar, 471 S.W.3d. 138, 147 (Tex. App. Austin 2015), 
    538 S.W.3d 89
    (Tex. 2017), wherein a Texas appellate court held “that the [Texas] franchise tax is
    not ‘a tax imposed or measured by net income’ and, therefore, that it does not fall
    within chapter 141’s definition of an ‘income tax’. See Tex. Tax Code § 141.001,
    art. II.4.” Relying on Graphic Packaging, the Department also seeks to distinguish
    the Texas franchise tax from the earnings tax addressed in Scramuzza.
    First, this Court is not bound by a Texas appellate court decision interpreting
    a provision of a Texas statute. Second, Graphic Packaging did not address whether
    11
    the franchise tax was an income tax pursuant to La.R.S. 47:33. Moreover, in
    affirming the appellate court, the Texas Supreme Court did not reach that conclusion,
    stating: “Even were we to agree with Graphic that its franchise tax for the years in
    question amounted to the same thing as chapter 141’s income tax (an issue we do
    not decide) . . . . ” Graphic Packaging, 538 S.W.3d at 96. Thus, the supreme court
    of Texas has not so declared.9
    Additionally, with respect to the Department’s specific argument relative to a
    gross receipts tax as discussed in Graphic Packaging, we find that the district court
    in this case correctly referenced and relied upon the United States Supreme Court in
    Wynne, 
    135 S.Ct. 1787
    , as authority. In Wynne, the United States Supreme Court
    directly addressed the distinction between a tax on gross receipts and a tax on net
    income in the context of a dormant Commerce Clause analysis. The Wynne Court
    opined that the nature of the tax is determined by its practical effect. Specifically,
    the Court stated that it saw “no reason why the distinction between gross receipts
    and net income should matter, particularly in light of the admonition that we must
    consider ‘not the formal language of the tax statute but its practical effect.’” Wynne,
    
    135 S.Ct. at 1795
     (quoting Complete Auto Transit, Inc. v. Brady, 
    430 U.S. 274
    , 279,
    
    97 S.Ct. 1076
    , 1079 (1977)). The Wynne Court stated:
    And we have now squarely rejected the argument that the Commerce
    Clause distinguishes between taxes on net and gross income. See

    The Department filed a supplemental brief to discuss the recent decision of Goggin v. State Tax
    Assessor, 
    191 A.3d 341
     (Me. 2018). We are not persuaded by that decision wherein a Maine
    resident, who was a member of a New Hampshire LLC, sought Maine’s tax credit for business
    taxes imposed by New Hampshire on the LLC. The court found that Maine’s credit for income tax
    paid in another state did not include business taxes paid in the other state. The Goggin court noted,
    first, that the LLC was an out-of-state (New Hampshire) LLC; therefore, the LLC was bound by
    New Hampshire’s tax laws, not Maine’s tax laws. “Second, the term ‘income tax’ in Maine’s
    statute is a term of art” that provides “a credit only for income taxes paid by individuals on income
    derived from other states[,]” and it did not apply to taxes imposed on business entities. Id. at 346.
    Thus, the Maine case is readily distinguishable.

    For the foregoing reasons, we hold that a taxpayer’s payment of Texas
    franchise taxes under the 2006 revisions of the Texas statutes are income taxes
    pursuant to the 2015 revisions of La.R.S. 47:33, as amended by Act 109. In so
    concluding, we reject the Department’s invitation to resolve this matter on statutory
    grounds without reaching the constitutional question before this Court.10 Having
    found that the Texas franchise tax is income tax for purposes of La.R.S. 47:33, we
    must next address whether the district court erred in finding Act 109 to be
    unconstitutional.
    The Dormant Commerce Clause
    The Department argues that even if the Texas franchise tax is an income tax
    for purposes of La.R.S. 47:33, it, nevertheless, does not violate the dormant
    Commerce Clause. As an initial matter, we note that statutes are presumed to be
    constitutional; therefore, the party challenging the validity of the statute bears the
    burden of proving that statute to be unconstitutional.11 The “party challenging the
    10
    “Courts ‘should avoid constitutional rulings when the case can be disposed of on non-
    constitutional grounds.’” Burmaster v. Plaquemines Par. Gov’t., 07-2432, p. 7 (La. 5/21/08),

    constitutionality of a statute must point to a particular provision of the constitution
    that would prohibit the enactment of the statute, and must demonstrate clearly and
    convincingly that it was the constitutional aim of that provision to deny the
    legislature the power to enact the statute in question.” 12 Finally, the presumption of
    constitutionality is especially forceful in cases involving statutes related to taxation
    and public finance.13 With these principles in mind, we now turn to the merits of
    the dormant Commerce Clause challenge.
    “The Commerce Clause grants Congress power to ‘regulate Commerce . . .
    among the several States.’ Art. I, § 8, cl. 3.” Wynne, 
    135 S.Ct. at 1794
    . “Although
    the Clause is framed as a positive grant of power to Congress, ‘we have consistently
    held this language to contain a further, negative command, known as the dormant
    Commerce Clause, prohibiting certain state taxation even when Congress has failed
    to legislate on the subject.’” 
    Id.
     (quoting Jefferson Lines, Inc., 
    514 U.S. at 179
    ).
    The United States Supreme Court established a four-part test to assess the
    validity of state taxes under the Commerce Clause in Complete Auto Transit, Inc.,
    
    430 U.S. 274
     (“Complete Auto”). Under the Complete Auto test, a state tax on
    interstate commerce is upheld if the tax: (1) is applied to an activity with a
    substantial nexus with the taxing state; (2) is fairly apportioned; (3) does not
    discriminate against interstate commerce; and, (4) is fairly related to the services
    provided by the state. 
    Id. at 279

    of a substantial nexus with the state or the lack of a fair relationship to the services

    provided by the state. Taxpayers argue that Act 109 violates the second and third
    prong of the Complete Auto test pertaining to the apportionment of the tax and
    discrimination against interstate commerce.
    The second prong of the Complete Auto test “‘ensures that each State taxes
    only its fair share of an interstate transaction.’” Jefferson Lines, Inc., 
    514 U.S. at 184
     (quoting Goldberg v. Sweet, 
    488 U.S. 252
    , 260-61, 
    109 S.Ct. 582
    , 588 (1989)).
    In Jefferson Lines, the Supreme Court recognized that since Goldberg, it has
    “assessed any threat of malapportionment by asking whether the tax is ‘internally
    consistent’ and, if so, whether it is ‘externally consistent’ as well.” Id. at 185
    (quoting Goldberg, 
    488 U.S. at 261
    ).
    In Wynne, 135 S.Ct at 1802 (quoting Jefferson Lines, 
    514 U.S. at 185
    ), the
    Court explained the application of the internal consistency test, which “‘looks to the
    structure of the tax at issue to see whether its identical application by every State in
    the Union would place interstate commerce at a disadvantage as compared with
    commerce intrastate.’” The Department contends that Act 109 meets the internal
    consistency test because “[i]f every state offered the same credit against income
    taxes as does Louisiana, all [states] would grant a credit that precisely reduced the
    taxpayers in-state income tax to the same amount they would pay if they earned all
    that income in-state.” The Department argues that in such instance, “[a]ny additional
    tax owed by the in-state taxpayer would simply result from the higher rate charged
    on the income by a foreign state,” and “the dormant Commerce Clause does not
    protect interstate commerce from a succession of taxes by differing jurisdictions.”
    Moorman Mfg. Co., 
    437 U.S. 267
    ; Jefferson Lines, 
    514 U.S. 175
    .
    As stated hereinabove, even if a tax is internally consistent, it must also meet
    the second component of fair apportionment, i.e., external consistency. Jefferson
    Lines, 
    514 U.S. at 184
    . External consistency looks to “the economic justification for
    15
    the State’s claim upon the value taxed, to discover whether a State’s tax reaches
    beyond that portion of value that is fairly attributable to economic activity within the
    taxing State.” 
    Id.
     at 185 (citing Goldberg, 
    488 U.S. at 262
    ). “[T]he threat of real
    multiple taxation (though not by literally identical statutes) may indicate a State’s
    impermissible overreaching.” 
    Id.
    Taxpayers argue that Act 109 fails the fair apportionment test because its tax
    liability does not reasonably reflect how and where Taxpayers’ income is generated.
    Act 109 fails to fairly apportion the tax according to each state’s relation to the
    income. Since no credit is given with respect to the taxes paid on income earned
    from sources in Texas, Taxpayers maintain that Act 109 fails to apportion the out-
    of-state income in the first instance. Not only is it not apportioned, it creates the
    potential for multiple taxation of the same income. We agree with Taxpayers that
    Act 109 fails the external consistency test.
    The third prong of the Complete Auto test addresses whether the state tax
    discriminates against interstate commerce. “A State may not ‘impose a tax which
    discriminates against interstate commerce . . . by providing a direct commercial
    advantage to local business.’” Jefferson Lines, 
    514 U.S. at 197
     (quoting
    Northwestern States Portland Cement Co. v. Minnesota, 
    358 U.S. 450
    , 458, 
    79 S.Ct. 357
    , 362 (1959)). “Thus, States are barred from discriminating against foreign
    enterprises competing with local business . . . and from discriminating against
    commercial activity occurring outside the taxing State[.]” 
    Id.
     (citations omitted).
    The Department states that there is no discrimination in this case because it
    has repeatedly been acknowledged by the United States Supreme Court that
    interstate commerce can be subject to a myriad of different taxes as it moves through
    the distribution chain. 14 The Department then makes the conclusory statement that
    14
    The Department quotes the following language from Jefferson Lines, Inc., 
    514 U.S. at
    187-88:
    16
    “the imposition of Louisiana income tax and Texas franchise tax to the Taxpayers’
    interstate activity does not discriminate against interstate commerce or violate the
    dormant Commerce Clause.” However, under the third prong of Complete Auto, the
    inquiry is whether the tax discriminates by disparate treatment between interstate
    and intrastate commerce.
    Taxpayers maintain that Act 109 discriminates against interstate commerce in
    two ways. First, the amended language of La.R.S. 47:33(A)(4) exposes one hundred
    percent of the interstate income of Louisiana residents to double taxation. By virtue
    of their ownership in the Pass-Through Entities, which earned income was derived
    from sources in Texas, Taxpayers paid taxes on income from Texas sources.
    Additionally, since Texas has no reciprocal credit provision, Act 109 does not allow
    a credit to Taxpayers on their Louisiana income taxes for the income taxes they paid
    on the revenue earned from Texas sources. Therefore, in this case, Taxpayers are
    paying income tax twice on their interstate income. However, on income earned in
    Louisiana, Taxpayers pay only the Louisiana income tax.
    In deriving this rule covering taxation to a buyer on sales of goods we were
    not, of course, oblivious to the possibility of successive taxation of related events
    up and down the stream of commerce, and our cases are implicit with the
    understanding that the Commerce Clause does not forbid the actual assessment of
    a succession of taxes by different States on distinct events as the same tangible
    object flows along. Thus, it is a truism that a sales tax to the buyer does not preclude
    a tax to the seller upon the income earned from a sale, and there is no constitutional
    trouble inherent in the imposition of a sales tax in the State of delivery to the
    customer, even though the State of origin of the thing sold may have assessed a
    property or severance tax on it. See [McGoldrick v. Berwind-White Coal Mining
    Co., 
    309 U.S. 33
    , 53, 
    60 S.Ct. 388
    , 396]; cf. Commonwealth Edison Co. v. Montana,
    
    453 U.S. 609
    , 
    101 S.Ct. 2946
    , 
    69 L.Ed.2d 884
     (1981) (upholding severance tax on
    coal mined within the taxing State). In light of this settled treatment of taxes on
    sales of goods and other successive taxes related through the stream of commerce,
    it is fair to say that because the taxable event of the consummated sale of goods has
    been found to be properly treated as unique, an internally consistent, conventional
    sales tax has long been held to be externally consistent as well.
    17
    Additionally, Taxpayers state that La.R.S. 47:33(A)(5) provides another
    provision for the double taxation of a portion of a Louisiana resident’s interstate
    income. The amended language now provides that even if a state offers a reciprocal
    credit (thereby satisfying the requirement of La.R.S. 47:33(A)(4)), the amount of the
    credit is limited to the amount of Louisiana income tax a taxpayer would have paid
    if the income had been earned in Louisiana. Therefore, the effect is to discriminate
    against interstate commerce by twice taxing a portion of a taxpayer’s out-of-state
    income.
    We agree with Taxpayers that Act 109 results in the double taxation of
    interstate income as compared with the taxation of intrastate income. This disparate
    treatment impermissibly discriminates against interstate commerce, and it fails the
    third prong of the Complete Auto test. Our conclusion herein is supported by the
    reasoning and holding in Wynne.
    As stated above, the district court found Wynne to be dispositive on the issue
    of the constitutionality of Act 109.      We likewise find Wynne instructive and
    applicable herein.    Not only did Wynne eliminate any question regarding the
    distinction between taxes on net and gross income, as in the instant matter, but it also
    involved the potential tax liability of shareholders of an S corporation and whether
    the Maryland tax law violated the dormant Commerce Clause.
    As analyzed in Wynne, 
    135 S.Ct. 1787
    , Maryland imposed an income tax on
    its residents for income earned inside and outside Maryland, which was composed
    of a state income tax and a county income tax. If a Maryland resident paid income
    tax to another state for income earned there, Maryland allowed the taxpayer a credit
    against the state portion of the tax paid to the other state, but not the county portion
    of the tax. According to the Maryland tax scheme, income of nonresidents was also
    taxed in two parts. Nonresidents were required to pay the Maryland state income
    18
    tax on all income that was earned from sources within Maryland. Nonresidents, not
    subject to the county tax, were required to pay a “special nonresident tax” in lieu of
    the county tax. Wynne, 
    135 S.Ct. at 1792
    . The “special nonresident tax” was levied
    on income earned from sources within Maryland. Maryland did not tax the income
    of nonresidents earned from sources outside Maryland. 
    Id.
    The taxpayers in Wynne were Maryland residents who owned stock in an
    S corporation, which earned income and filed state income tax returns in multiple
    states. The taxpayers earned pass-through income from the S corporation. When
    filing their Maryland tax returns, the Wynnes claimed an income tax credit for the
    income taxes paid to other states. The Maryland Comptroller of the Treasury
    allowed the credit only for the state portion of the income tax and disallowed the
    credit for the county income tax.
    The Wynne court addressed whether Maryland’s taxation on income was a
    violation of the dormant Commerce Clause. Reasoning that the dormant Commerce
    Clause prohibits states from discriminating against interstate commerce by
    subjecting it to a higher tax that would be collected if the commerce were solely
    intrastate, the Court stated:
    Under our precedents, the dormant Commerce Clause precludes
    States from “discriminat[ing] between transactions on the basis of some
    interstate element.” Boston Stock Exchange v. State Tax Comm’n, 
    429 U.S. 318
    , 332, n. 12, 
    97 S.Ct. 599
    , 
    50 L.Ed.2d 514
     (1977). This means,
    among other things, that a State “may not tax a transaction or incident
    more heavily when it crosses state lines than when it occurs entirely
    within the State.” Armco Inc. v. Hardesty, 
    467 U.S. 638
    , 642, 
    104 S.Ct. 2620
    , 
    81 L.Ed.2d 540
     (1984). “Nor may a State impose a tax which
    discriminates against interstate commerce either by providing a direct
    commercial advantage to local business, or by subjecting interstate
    commerce to the burden of ‘multiple taxation.’ ” Northwestern States
    Portland Cement Co. v. Minnesota, 
    358 U.S. 450
    , 458, 
    79 S.Ct. 357
    , 
    3 L.Ed.2d 421
     (1959) (citations omitted).
    Id. at 1794. Addressing Maryland’s particular tax provisions, the Court stated:
    19
    This case involves the constitutionality of an unusual feature of
    Maryland’s personal income tax scheme. Like many other States,
    Maryland taxes the income its residents earn both within and outside
    the State, as well as the income that nonresidents earn from sources
    within Maryland. But unlike most other States, Maryland does not offer
    its residents a full credit against the income taxes that they pay to other
    States. The effect of this scheme is that some of the income earned by
    Maryland residents outside the State is taxed twice. Maryland’s scheme
    creates an incentive for taxpayers to opt for intrastate rather than
    interstate economic activity.
    Id. at 1792.
    The Wynne Court discussed tax schemes it had previously found to be
    unconstitutional 15 because they “had the potential to result in the discriminatory
    double taxation of income earned out of state and created a powerful incentive to
    engage in intrastate rather than interstate economic activity.” Id. at 1801-02.
    Although it did not use the term in those decisions, the Court recognized that it “held
    that those schemes could be cured by taxes that satisfy what [it has] subsequently
    labeled the ‘internal consistency’ test.” Id. at 1802 (quoting Jefferson Lines, 
    514 U.S. at 185
    ). After conducting the internal consistency test, the United States
    Supreme Court concluded that “Maryland’s income tax scheme fails the internal
    consistency test.” Id. at 1803 (footnote omitted).
    In reaching its ultimate conclusion, the Wynne Court explained that “[t]he
    critical point is that the total tax burden on interstate commerce is higher, not that
    Maryland may receive more or less tax revenue from a particular taxpayer.” Id. at
    1805. Further, “[t]hat Maryland’s existing tax unconstitutionally discriminates
    against interstate commerce is enough to decide this case.” Id. at 1806. For these

    reasons, the Supreme Court held that Maryland’s tax scheme violated the federal
    constitution.
    Like the effect of Maryland’s tax scheme, Act 109’s failure to provide a credit
    results in the double taxation of income that is earned outside Louisiana, i.e.,
    interstate commerce, but not intrastate income. Because the income, if earned in
    Louisiana, would only be taxed once, Act 109 “creates an incentive for taxpayers to
    opt for intrastate rather than interstate economic activity” which, pursuant to Wynne,
    is violative of the dormant Commerce Clause. Wynne, 
    135 S.Ct. at 1792
    . Louisiana
    residents who earn interstate income are forced into double taxation on all or a
    portion of their interstate income, whereas Louisiana residents with only intrastate
    income are not. This tax scheme impermissibly discriminates against interstate
    commerce and violates the dormant Commerce Clause of the United States
    Constitution. For the above reasons, we hold herein that Act 109 is unconstitutional.
    CONCLUSION
    We find that the Taxpayers’ payment of the franchise tax under the 2006
    revisions to Texas’ franchise tax provisions are income taxes paid to another state
    pursuant to the 2015 revisions of La.R.S. 47:33. Further, we hold that Act 109 is
    unconstitutional, as it is in violation of the dormant Commerce Clause of the United
    States Constitution.
    DECREE
    For the reasons stated herein, we affirm the judgment of the district court in
    its entirety.
    AFFIRMED.
