    JUSTICE LOPEZ authored the opinion of the Court, in which JUSTICES
    BOLICK, GOULD, and BALES (RETIRED) and JUDGE ECKERSTROM 1
    joined. VICE CHIEF JUSTICE TIMMER, joined by CHIEF JUSTICE
    BRUTINEL, concurred in part and dissented in part.
    JUSTICE LOPEZ, opinion of the Court:
    ¶1             We consider whether online travel companies (“OTCs”) like
    Orbitz Worldwide Inc. and the other appellants are subject to municipal
    privilege taxes under Model City Tax Code (“MCTC” or “the Code”)2
    §§ 444 and 447, and if so, whether the City of Phoenix and other city
    appellees (collectively the “Cities”) may assess those taxes, penalties, and
    interest retroactively. We hold that the OTCs are subject to taxation under
    1 Pursuant to article 6, section 3 of the Arizona Constitution, the Honorable
    Peter J. Eckerstrom, Judge of the Arizona Court Appeals, Division Two, was
    designated to sit in this matter.
    2 Although each of the Cities has passed its own tax ordinance, those
    ordinances are based on and do not differ substantively from the MCTC.
    Because the parties reference the MCTC in their briefs, we do so as well
    throughout this opinion.
    2
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    § 444 because they are “brokers”—as defined by MCTC § 100—engaging in
    “the business of operating a hotel,” and the proceeds from this business—
    their service fees and markups on room rental rates—constitute taxable
    gross income. We further hold that the OTCs are not subject to taxation
    under § 447 because they are not “hotels.” Finally, we hold that MCTC
    § 542(b) bars taxation based on a new policy, procedure, or interpretation
    of the Code until a city has adopted and provided impacted taxpayers with
    clear notice of the change, and we remand to the tax court to determine
    whether § 542(b) bars the Cities from assessing taxes, penalties, and interest
    due under § 444 before the 2013 Notices of Tax Assessment (“2013
    Assessments”).
    I.
    ¶2             The OTCs develop, operate, and maintain websites that offer
    travel-facilitation services. One of those services allows travelers to reserve
    and pay for hotel rooms. The OTCs do not own the hotels or rooms they
    advertise; they contract with the hotels to list rooms available for rent.
    ¶3              When a customer requests a hotel reservation, an OTC
    collects the customer’s personal and payment information and provides a
    total price for the room. The total price is a combination of the “Reservation
    Rate” or “Nightly Rate” and an amount representing the “Taxes and Fees”
    or “Tax Recovery Charge and Service Fees.” The “Reservation Rate”
    consists of the room rental rate set by the hotel in its contract with the OTC
    plus an additional markup that the OTC retains for its services. The “Taxes
    and Fees” consist of the tax rate the hotel later remits to the city as a
    privilege tax and an additional service fee paid to the OTC. The OTC does
    not disclose to the customer the amount of the markup on the room rental
    rate or the portion of the “Taxes and Fees” remitted for taxes.
    ¶4            Before finalizing a transaction with a customer, the OTC
    confirms the room rates and availability with the hotel and requests a
    reservation on the customer’s behalf. After the hotel confirms the
    reservation, the OTC charges the customer’s credit card, appearing on the
    statement as the merchant of record. Until the customer checks into the
    hotel, the OTC provides customer service support and facilitates any
    modifications or cancellations.
    3
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    ¶5            After a customer’s stay, the hotel invoices the OTC for the net
    room rate—not including the OTC’s markup—and the amount covering the
    tax owed by the hotel. The hotel then remits the tax to the city. Neither the
    OTC nor the hotel pays the city any money representing tax on the OTC’s
    service fees or markups.
    ¶6            In 2013, the Cities issued privilege tax assessments against the
    OTCs—the 2013 Assessments—following a multi-year audit of the OTCs’
    books and records. The assessments were based on the Cities’ position that
    the OTCs owed unpaid privilege taxes under §§ 444 and 447 for engaging
    in the business of operating hotels, or alternatively, for acting as brokers for
    hotels. The OTCs challenged the assessments, and in May 2014 an
    administrative hearing officer overturned them, concluding the OTCs were
    not subject to taxation under §§ 444 or 447 because the OTCs were neither
    hotel operators nor brokers.
    ¶7             In the ensuing appeal, the tax court partially granted and
    partially denied the Cities’ motion for summary judgment. The court
    concluded the OTCs do not own or operate hotels, but the OTCs “clearly
    and unambiguously” qualify as “brokers” under the Code and are subject
    to taxation under both §§ 444 and 447. The court also concluded that the
    Cities’ position on OTCs as “brokers” in the 2013 Assessments constituted
    “a new interpretation or application” under § 542(b), thus the Cities could
    only assess taxes prospectively.
    ¶8             The OTCs appealed the tax court’s ruling regarding their
    liability for taxes, and the Cities cross-appealed the ruling barring
    retroactive collection of the tax. The court of appeals held that the OTCs
    are subject to taxation under § 444 because they qualify as “brokers”
    engaging in the taxable activity under the provision, and the OTCs’
    proceeds from that activity—service fees and markups—are part of the
    taxable gross income. City of Phoenix v. Orbitz Worldwide Inc., Nos. 1 CA-TX
    16-0016; 1 CA-TX 16-0018, 
    2018 WL 4265950
    , at *3 ¶ 14 (Ariz. App. Sept. 6,
    2018) (mem. decision). It further held that the OTCs are not subject to
    taxation under § 447 because the tax liability of that provision is limited to
    hotels. Id. at *5 ¶ 27. Finally, the court held that the Cities could assess the
    taxes, penalties, and interest under § 444 retroactively, for years preceding
    the 2013 Assessments, “[b]ecause there was no change in the Cities’
    application or interpretation of the Code and the OTCs’ business activities
    are not new.” Id. at *6 ¶ 32.
    4
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    ¶9           We granted review because the applicability of municipal
    privilege taxes to the OTCs is a recurring legal issue of statewide
    importance. We have jurisdiction under article 6, section 5(3) of the
    Arizona Constitution.
    II.
    ¶10            “City . . . ordinances are to be construed by the same rules and
    principles which govern the construction of statutes,” Rollo v. City of Tempe,
    
    120 Ariz. 473
    , 474 (1978), and “we review issues of statutory interpretation
    de novo, seeking to effectuate the drafters’ intent.” City of Surprise v. Ariz.
    Corp. Comm’n, 
    246 Ariz. 206
    , 210 ¶ 10 (2019). “In construing a specific
    provision, we look to the statute as a whole and we may also consider
    statutes that are in pari materia—of the same subject or general purpose—
    for guidance and to give effect to all of the provisions involved.” Stambaugh
    v. Killian, 
    242 Ariz. 508
    , 509 ¶ 7 (2017). If possible, we give meaning “to
    every word and provision so that no word or provision is rendered
    superfluous.” Nicaise v. Sundaram, 
    245 Ariz. 566
    , 568 ¶ 11 (2019). If the
    language of a statute is unambiguous, “we apply it without further
    analysis.” Glazer v. State, 
    237 Ariz. 160
    , 163 ¶ 12 (2015).
    III.
    ¶11           We first address whether the OTCs are subject to taxation
    under § 444. This provision imposes a tax on “the gross income from the
    business activity upon every person engaging in or continuing in the
    business of operating a hotel charging for lodging.” Therefore, to be subject
    to taxation under § 444, the OTCs’ business activities must constitute “the
    business of operating a hotel,” the proceeds the OTCs receive from hotel
    customers in the form of markups and service fees must be part of the
    taxable gross income contemplated by § 444, and the OTCs must qualify as
    “persons” liable for the tax. We agree with the court of appeals that all three
    requirements are satisfied here. See Orbitz, 
    2018 WL 4265950
    , at *3 ¶ 14.
    ¶12          At the outset, we recognize that other jurisdictions have
    reached varying conclusions on whether OTCs are subject to taxes on hotel
    lodging. Compare, e.g., City & County of Denver v. Expedia, Inc., 
    405 P.3d 1128
    ,
    1138 ¶ 36 (Colo. 2017) (city ordinance taxed privilege of purchasing lodging
    and OTCs’ markups are inseparable from selling price of lodging), and
    5
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    Travelocity.com, L.P. v. Wyo. Dep’t of Revenue, 
    329 P.3d 131
    , 143 ¶ 41, 145 ¶ 55
    (Wyo. 2014) (OTCs qualify as “vendors,” taxable under city’s ordinance,
    and their markups are part of the “sales price” subject to city’s tax on hotel
    lodging), with State v. Priceline.com, Inc., 
    206 A.3d 333
    , 341 (N.H. 2019)
    (statute at issue explicitly limited lodging tax to “operators,” and OTCs did
    not qualify as hotel operators), and Pitt County v. Hotels.com, G.P., LLC, 
    553 F.3d 308
    , 313 (4th Cir. 2009) (same). Each of these cases was decided based
    on the language of the particular statute or ordinance at issue. Because the
    language of § 444 and the rest of the Code differs in several key respects—
    especially with respect to its treatment of “brokers”—we do not find these
    cases particularly instructive in resolving the issues before us. Instead, our
    analysis is guided by the language of the Code.
    A.
    ¶13             We agree with the court of appeals that the OTCs are engaged
    in the taxable business activity: “the business of operating a hotel.” Orbitz,
    
    2018 WL 4265950
    , at *4 ¶ 21. As a threshold matter, we note that § 444 is a
    transaction privilege tax because it levies “an excise tax on the privilege or
    right to engage in an occupation or business . . . . [It] is not a sales tax, but
    rather is a tax on the gross receipts of a person or entity engaged in business
    activities.” See Ariz. Dep’t of Revenue v. Action Marine, Inc., 
    218 Ariz. 141
    , 142
    ¶ 6 (2008) (internal quotations and citations omitted); see also MCTC § 400
    (broadly imposing privilege taxes); Rigel Corp. v. State, 
    225 Ariz. 65
    , 67 ¶ 12
    (App. 2010) (noting that transaction privilege taxes, as compared to sales
    taxes, are levied on gross receipts rather than individual sales and on
    business providers rather than consumers).
    ¶14            The taxable business activity under § 444 is “the business of
    operating a hotel.” Section 100 defines “business” to mean, in relevant part,
    “all activities or acts, personal or corporate, engaged in or caused to be
    engaged in with the object of gain, benefit, or advantage, either directly or
    indirectly.” This section also defines “hotel” as brick-and-mortar lodging
    places. 3 But the Code does not define what it means to “operate” such
    3 Under § 100, “‘Hotel’ means any public or private hotel, inn, hostelry,
    tourist home, house, motel, rooming house, apartment house, trailer, or
    other lodging place within the City offering lodging, wherein the owner
    thereof, for compensation, furnishes lodging to any transient, except foster
    6
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    locations. Because it does not appear from the context that the drafters
    intended a special meaning, we are guided by the word’s ordinary
    meaning. See State Tax Comm’n v. Peck, 
    106 Ariz. 394
    , 395 (1970); Antonin
    Scalia & Bryan A. Garner, Reading Law: The Interpretation of Legal Texts 69
    (2012) (“Words are to be understood in their ordinary everyday meanings
    – unless the context indicates that they bear a technical sense.”).
    ¶15            The OTCs and the dissent assert that the “business of
    operating a hotel” must be limited to the business activity of hotel owners
    and operators—those who physically own or furnish lodging to customers.
    See infra ¶ 49 (citing Pitt County, 
    553 F.3d at
    313 and Mont. Dep’t of Revenue
    v. Priceline.com, Inc., 
    354 P.3d 631
    , 635 (Mont. 2015)). We disagree. As we
    noted previously, supra ¶ 12, the cases upon which the dissent relies are
    inapposite because their holdings were decided based on the language of
    the particular statute or ordinance at issue. In Pitt County, the tax provision
    at issue levied a tax on “[o]perators of hotels, motels, tourist homes, tourist
    camps, and similar type businesses.” 
    553 F.3d at 311
    . Similarly, the
    Montana tax provision levied a tax on an “owner or operator” of lodging
    facilities. Mont. Dep’t of Revenue, 354 P.3d at 634 ¶ 8. Here, § 444 levies a
    much broader tax on “every person engag[ed] . . . in the business of operating
    a hotel.” (Emphasis added.)
    ¶16           In construing § 444, we look to the Code as a whole and
    attempt to give meaning “to every word and provision so that no word or
    provision is rendered superfluous.” See Nicaise, 245 Ariz. at 568 ¶ 11;
    Stambaugh, 242 Ariz. at 509 ¶ 7; Scalia & Garner, supra ¶ 14, at 167, 174
    (discussing the “Whole-Text” and “Surplusage” canons). And while the
    drafters used specific language to limit the additional tax liability of § 447
    to the gross income of “hotels,” 4 they chose not to do the same for § 444.
    This difference suggests that the tax liability of § 444 extends beyond the
    hotels’ owners and operators. Indeed, § 444 expressly imposes the tax on
    the entire business activity and on every “person” engaged in that activity.
    See infra ¶¶ 29–30 (discussing the Code’s treatment of the defined term
    “person” and how it applies to the OTCs).
    homes, rest homes, sheltered care homes, nursing homes, or primary health
    care facilities.”
    4 Section 447 levies a tax on “the gross income from the business activity
    of any hotel engaging or continuing within the City in the business of
    charging for lodging.”
    7
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    ¶17           The dissent further suggests that § 447 and § 444 impose taxes
    on the same taxpayer (i.e., hotel operators). Infra ¶ 52. We disagree.
    Although § 447 does not identify a specific taxpayer, it identifies the taxable
    gross income as “the gross income from the business activity of any hotel.”
    This taxable gross income is distinctly different than that identified in § 444:
    the gross income from the entire business activity and on every person
    engaged in that activity. Because the taxable gross income differs between
    the two provisions, the impacted taxpayer may differ as well. The fact that
    the tax under § 447 is “[i]n addition to” the tax under § 444 simply means
    that some of the taxpayers liable for the § 444 tax (i.e., hotel owners and
    operators) will also be liable for the § 447 tax. While the dissent ignores the
    drafters’ choice to use different language to distinguish the tax liabilities of
    §§ 444 and 447, we interpret this difference to mean that § 444 applies more
    broadly—with respect to both taxable gross income and taxpayers—than
    § 447.
    ¶18            Thus, we reject the OTCs’ and dissent’s assertion and consider
    the more expansive meaning of “operating a hotel.” As a transitive verb,
    “operate” means “to put or keep in operation.” Operate, Merriam-Webster,
    https://www.merriam-webster.com/dictionary/operate (last visited
    September 4 , 2019). And “operation” means “the quality or state of being
    functional or operative.”          Operation, Merriam-Webster, https://
    www.merriam-webster.com/dictionary/operation (last visited September
    4, 2019). Considering these ordinary meanings and the definitions
    provided by the Code, we conclude that § 444 imposes a tax liability on any
    “person”—not just a hotel owner or operator—that engages for profit in
    business activities that are central to keeping brick-and-mortar lodging
    places functional or in operation. Because the function of hotels—as
    defined by the Code—is to furnish lodging to transients, the taxable
    business activities are those that are essential to furnishing lodging. See
    § 100 (definition of “hotel”).
    ¶19            Undeniably, the OTCs engage in those types of business
    activities. From the time a customer makes a credit card payment until the
    customer physically checks into the hotel, the OTCs facilitate all aspects of
    the transaction and receive compensation in the form of service fees and
    markups on the room rental rates for providing their services. It would be
    illogical to conclude that the OTCs—which advertise available rooms,
    solicit potential customers, collect customers’ information, process
    8
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    payments, confirm reservations, provide customer service, and facilitate
    reservation modifications and cancellations—are not actively engaged in
    “the business of operating a hotel.” Indeed, all these services provided by
    the OTCs are central to keeping a hotel functional and in operation.
    ¶20            We similarly reject the OTCs’ related argument that they are
    not engaged in the taxable business activity of “operating a hotel” because
    they perform only a limited number of hotel operations before customers
    check into the hotels. Nothing in the Code suggests that the taxable gross
    income of § 444 is limited to the income of persons who perform all the
    functions of a hotel. On the contrary, the fact that the drafters of § 444
    imposed the tax on the gross income of the broadly defined “person”
    (which includes “brokers,” infra ¶ 29) rather than the more narrowly
    defined “hotel” necessarily implies that the drafters intended to tax the
    gross income of all persons engaged in hotel operations and not just the
    gross income of those who perform all the functions of a hotel. See City of
    Flagstaff v. Mangum, 
    164 Ariz. 395
    , 398 (1990) (“Where the legislature uses a
    term within one statute and excludes it from another, the term usually will
    not be read into the provision from which it was excluded.”).
    ¶21            The dissent contends that our holding here “necessarily
    imposes [§ 444 tax liability] on [other] persons and entities . . . who offer
    hotel booking services for a profit,” such as “airlines, credit card companies,
    [and] brick-and-mortar travel agents.” Infra ¶ 54. We agree. As adduced
    in the record and during oral argument, hotels already remit taxes based on
    the full amount charged to hotel customers, with no deductions for
    markups or service fees, when brick-and-mortar travel agents and credit
    card companies (e.g., American Express Travel) facilitate hotel lodging but
    customers pay the entire transaction amount to the hotel. That brick-and-
    mortar travel agents and credit card companies’ service fees, like the OTCs’,
    may be taxable if customers pay such entities directly rather than hotels is
    not an unintended consequence. But the dissent takes this one step further,
    suggesting that our holding would also impose tax liability on “third-party
    entities who provide maintenance, housekeeping, [and] gardening.” Infra
    ¶ 55. On this point, such secondary services are plainly distinguishable
    from those performed by the OTCs and are not necessarily central to the
    primary function of a hotel to furnish lodging. Nor, unlike the OTCs, are
    those service providers “brokers.” See infra ¶¶ 29–30. But we need not
    decide this issue here because the applicability of § 444 to such entities has
    not been briefed and is not before us.
    9
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    ¶22            The OTCs argue generally that we must reject the court of
    appeals’ and Cities’ interpretations here and of other portions of the Code
    discussed below because the language is not clear and unambiguous, and
    any ambiguity must be resolved in the OTCs’ favor. The dissent echoes this
    argument for our holding regarding § 444. Infra ¶ 56. It is a well-settled
    rule in Arizona that ambiguities in “revenue statute[s] should be construed
    liberally in favor of the taxpayer and strictly against the state.” See Ebasco
    Servs. Inc. v. Ariz. State Tax Comm’n, 
    105 Ariz. 94
    , 97 (1969). But this rule
    only applies if, after exhausting all other tools of statutory construction, a
    court concludes that a statute remains ambiguous. See BSI Holdings, LLC v.
    Ariz. Dep’t of Transp., 
    244 Ariz. 17
    , 22 ¶ 25 (2018). The rule does not apply
    here because, after employing relevant tools of statutory construction, we
    do not find the language of § 444 or its accompanying definitions
    ambiguous.
    B.
    ¶23            We also agree with the court of appeals that the markups and
    service fees the OTCs collect from hotel customers are part of the gross
    income taxable under § 444. See Orbitz, 
    2018 WL 4265950
    , at *4 ¶¶ 22–24.
    The OTCs would have us limit the taxable gross income under § 444 to the
    gross income of hotels, but such an interpretation conflicts with the express
    language of the provision and its accompanying definitions. Section 200
    broadly defines “gross income” to include all proceeds from a taxable
    activity, 5 and § 444 imposes a tax on the gross income of every “person”
    engaged in the business of operating hotels. As established above, the
    OTCs are engaged in the business of operating hotels. See supra ¶¶ 13–19.
    5   Gross income, under § 200(a), includes:
    (1) the value proceeding or accruing from the sale of property,

    Opinion of the Court
    And in the conduct of that business, the OTCs charge hotel customers
    service fees and markups on the hotel room rental rates. Thus, the OTCs’
    service fees and markups constitute proceeds from the taxable activity and
    are part of the taxable gross income contemplated by § 444. See § 400(c)
    (establishing a presumption “that all gross income . . . is subject to the tax
    until the contrary is established by the taxpayer”).
    ¶24            The OTCs argue their service fees and markups are exempt
    from § 444 taxation because the income they receive from customers is for
    “travel-facilitation, non-lodging services,” such as comparison shopping
    and loyalty programs, which differ from the services offered by hotels. We
    are unpersuaded. Although the OTCs may provide some services that the
    hotels do not, the OTCs also provide hotel customers with numerous
    services that are central to operating hotels and, like the hotels, are subject
    to § 444 taxation on the gross income from the provision of those services.
    ¶25           Clearly, if a hotel were to fractionalize all the aspects of
    operating the hotel, charging separately for reservation services,
    advertising, and customer support, the hotel would still be subject to § 444
    taxation on the income from those services. See § 444 (taxing the gross
    income generated by “operating a hotel charging for lodging”) (emphasis
    added); § 100 (defining “lodging” to include “services and accommodations
    accompanying the use and possession of [a] dwelling space”). Therefore,
    the OTCs—which do not distinguish in their markups and service fees their
    hotel-related services from other services they may provide—cannot
    eliminate their service fees and markups from the taxable gross income
    based on the other services they provide.
    ¶26           Indeed, failure to include the OTCs’ service fees and markups
    in the taxable gross income results in illogical and unjustifiable tax
    consequences. The OTCs conceded at oral argument that if a customer
    reserves a room on an OTC site but chooses to pay the full amount charged
    by an OTC directly to the hotel, the hotel remits taxes on the entire amount.
    But if the customer opts to pay the OTC, the hotel remits taxes on a lesser
    amount. For example, assume an OTC contracts with a hotel for a
    discounted net rental rate of $100 in a city with a combined 10% occupancy
    tax. The OTC then advertises the room for $150, plus an additional $15 for
    taxes and service fees. If a customer pays the hotel $165, the hotel keeps
    $100, remits $16.50 to the city, and pays the OTC the remaining $48.50. If a
    customer pays the OTC instead, the hotel invoices the OTC after the
    11
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    customer’s stay for $110, keeping $100 and remitting $10 to the city. The
    OTC keeps the remaining $55. Thus, in this example, the customer’s choice
    between paying the hotel and paying the OTC would result in a difference
    of $6.50 in the amount of taxes paid to the city—an approximately 40%
    reduction in tax revenue to the city if the customer pays the OTC. Although
    this disparity could be justified if § 444 explicitly imposed a tax solely on
    the gross income of hotels, it cannot be justified when the statute imposes
    the tax on the entire business activity and on every “person” engaged in
    that activity. See supra ¶ 16.
    ¶27            The dissent categorizes this disparity as “a matter of policy
    that should be left to the MCTC drafters, not this Court.” Infra ¶ 57. But
    the dissent’s argument is premised on its assumption that the gross income
    taxed by § 444 does not cover the total amount paid by hotel guests. Id.
    Because we conclude that the tax liability of § 444 does apply to the total
    amount by applying to the entire taxable business activity and on every
    person engaged in that activity, supra ¶¶ 16, 23, we reject the dissent’s
    assertion that this disparity is merely a “loophole.” See infra ¶ 57 (citing Pitt
    County, 
    553 F.3d at
    314 and Louisville/Jefferson Cty. Metro Gov’t v. Hotels.com,
    L.P., 
    590 F.3d 381
    , 388–89 (6th Cir. 2009)).
    ¶28           The OTCs also argue that their service fees are excluded from
    taxation under § 444(b)(5), which excludes “[g]ross proceeds of sales or
    gross income from commissions received from a person providing services
    or property to the customers of the hotel.” But even if we accept that the
    OTCs’ service fees constitute a commission, the MCTC Regulations
    expressly provide that “brokers shall be wherever necessary treated as
    taxpayers for all purposes” and “[n]o deduction shall be allowed for any
    commissions or fees retained by . . . broker[s],” absent limited exceptions
    inapplicable here. MCTC Reg. 100.1(a); see infra ¶¶ 29–31 (concluding that
    OTCs qualify as “brokers” under the Code). More importantly, the OTCs
    receive their service fees from hotel customers, not persons “providing
    services or property” to those customers.
    C.
    ¶29           We further agree with the court of appeals that the OTCs
    qualify as “persons” subject to the tax liability of § 444 because they are
    “brokers.” See Orbitz, 
    2018 WL 4265950
    , at *3 ¶¶ 15–20. Section 444 imposes
    a tax on the gross income of all “persons” engaged in the taxable business
    12
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    activity. In turn, § 100 defines “person” to include numerous entities,
    including a “broker,” and defines “broker” as “any person engaged or
    continuing in business who acts for another for a consideration in the
    conduct of a business activity taxable under this Chapter, and who receives
    for his principal all or part of the gross income from the taxable activity.”
    Thus, to qualify as “brokers” under the Code’s definition, the OTCs must
    be (1) acting for the hotels for a consideration, (2) conducting “the business
    of operating a hotel,” and (3) receiving for the hotel all or part of the gross
    income of that business.
    ¶30            As discussed above, the OTCs are engaged in “the business of
    operating a hotel,” supra ¶¶ 13–19, and the income they receive in the form
    of service fees and markups is part of the taxable gross income under § 444,
    supra ¶¶ 20–24. The OTCs also regularly collect from hotel customers the
    entire costs of the lodging, remitting only portions of it to the hotels. As to
    the last point, the OTCs argue that to the extent they may act as “brokers,”
    they do so only for travelers, not hotels. We disagree. The OTCs may
    provide broker-like services for hotel customers, but they also act for the
    hotels by providing services central to operating the hotels, including
    advertising, booking, and customer support. Although MCTC Regulation
    100.1(b) refers to a property manager as an example of a “broker,” it is only
    an example and not an exhaustive list; in fact, it is offered to illustrate only
    the unrelated proposition that a broker property manager may have to pay
    the privilege tax even if the principal has no tax liability.
    ¶31           In sum, the OTCs fulfill all the requirements to satisfy the
    statutory definition of “brokers,” their service fees and markups are part of
    the gross income contemplated by § 444, and the services they provide to
    hotel customers qualify as “the business of operating a hotel.”
    Additionally, the Code’s Regulations recognize that the taxable gross
    income under § 444 includes the income of “brokers” engaged in the taxable
    business activity. See MCTC Reg. 100.1(a) (“[B]rokers shall be wherever
    necessary treated as taxpayers for all purposes . . . . No deduction shall be
    allowed for any commissions or fees retained by . . . broker[s] . . . .”). For
    these reasons, we hold that the OTCs’ service fees and markups on hotel
    room rental rates are subject to taxation under § 444.
    13
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    IV.
    ¶32            We next address whether the OTCs are subject to taxation
    under § 447. Unlike § 444, which imposes a tax on the gross income of
    “every person engag[ed] . . . in the business of operating a hotel,” § 447
    imposes an additional tax only on the gross income of “hotel[s].”
    Specifically, this provision levies a tax on “the gross income from the
    business activity of any hotel engaging or continuing within the City in the
    business of charging for lodging.” § 447. The court of appeals held “that
    the language of [§ 447] limits taxpayers to hotels renting lodging to
    customers. It does not extend to brokers engaging in hotel operations, as
    reflected in other sections of the Code.” Orbitz, 
    2018 WL 4265950
    , at *5 ¶ 27.
    We agree. The Code’s definition of “hotel” is expressly limited to brick-
    and-mortar lodging places; it does not include a “broker” for a hotel or any
    other entity remotely affiliated with an OTC. See MCTC § 100 (definition of
    “hotel”). Thus, the gross income of the hotels—the taxable gross income
    under § 447—does not include the OTCs’ income (i.e., markups and service
    fees).
    ¶33            The Cities argue § 447—like § 444—applies to the gross
    income of the entire lodging transaction, including any income earned by
    “brokers,” because § 447 must be read in conjunction with MCTC § 400,
    which establishes the legal presumption that the privilege taxes are upon
    all “gross income of persons.” (Emphasis added.) The Cities also cite to the
    Code’s definition of “gross income,” which broadly encompasses all value
    derived from the taxable activity. See MCTC § 200(a). We disagree that
    § 447 can be interpreted so expansively. Section 400 imposes privilege taxes
    only “upon persons on account of their business activities, to the extent
    provided elsewhere in this [a]rticle.” (Emphasis added.) And despite the
    Code’s broad definition of “gross income,” § 447 “limits the taxable income
    to business activities of hotels.” See Orbitz, 
    2018 WL 4265950
    , at *5 ¶ 27.
    ¶34           The Cities further argue that § 447 must be interpreted to
    apply to “brokers” because limiting tax liability under the provision to
    hotels will allow hotels to evade those taxes by setting up online shell
    companies to broker their hotel room transactions. The Cities cite to the
    MCTC Regulations, which state that “to prevent evasion of taxes
    imposed . . . brokers shall be wherever necessary treated as taxpayers for
    all purposes.” See MCTC Reg. 100.1(a). We disagree that our holding will
    inspire—much less allow—such activity. The Code explicitly contemplates
    14
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    and preempts any measures taken to evade taxes: Sections 210 and 220
    expressly authorize tax collectors to examine transactions between
    affiliated companies or persons, as well as transactions potentially made to
    evade taxes, to determine the appropriate gross income subject to tax. And
    in the event a hotel is using a broker to evade tax liability under § 447, the
    city could invoke MCTC Reg. 100.1(a) to collect from the broker. Further,
    as noted previously, supra ¶¶ 29–31, “brokers” are taxpayers for purposes
    of assessing tax liability under § 444. Thus, for purposes of interpreting
    § 447, it is not necessary to apply the provision beyond its terms to prevent
    tax evasion.
    V.
    ¶35            Having established that the OTCs are subject to taxation
    under § 444, we next consider the Cities’ authority to assess the taxes,
    penalties, and interest under § 444 against the OTCs retroactively, before
    the 2013 Assessments. MCTC § 542(b) provides that if a city “adopts a new
    interpretation or application of any [MCTC] provision . . . or determines
    that any provision applies to a new or additional category or type of
    business and the change in interpretation or application is not due to a
    change in the law,” then the city “shall not assess any tax, penalty or interest
    retroactively based on the change in interpretation or application.” 6 The
    tax court concluded that the Cities are barred from retroactive assessments
    before 2013 because the Cities never attempted to apply or enforce the taxes
    prior to that year. The court of appeals reversed the tax court and held that
    the Cities were permitted to collect taxes for the years preceding the 2013
    Assessments “[b]ecause there was no change in the Cities’ application or
    interpretation of the Code and the OTCs’ business activities are not new.”
    Orbitz, 
    2018 WL 4265950
    , at *6 ¶ 32.
    ¶36           As an initial matter, we note that the language of § 542(b) is
    framed in the disjunctive, barring retroactive assessment of taxes, penalties,
    and interest when a city “adopts a new interpretation or application” apart
    from a change in the law. (Emphasis added.) Thus, either a new
    interpretation or a new application of § 444 suffices to bar the Cities from
    assessing the taxes, penalties, and interest of § 444 retroactively. See Devenir
    Assocs. v. City of Phoenix, 
    169 Ariz. 500
    , 503 (1991) (“The court must, if
    possible, give meaning to each clause and word in the statute or rule to
    6   Section 542(b) mirrors its state tax code counterpart, A.R.S. § 42-2078.
    15
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    avoid rendering anything superfluous, void, contradictory, or
    insignificant.”). The Code does not explicitly define either “interpretation”
    or “application,” but it does state that these terms “include[] policies and
    procedures which differ from established interpretations of this Chapter.”
    See § 542(c); cf. A.R.S. § 42-2078(D) (stating that “’new interpretation or
    application’ includes policies and procedures adopted by administrative
    rule, tax ruling, tax procedure or instructions to a tax return”). And
    “application” is commonly defined as “an act of putting something to use.”
    Application,    Merriam-Webster,      https://www.merriam-webster.com/
    dictionary/application (last visited September 4, 2019). Based on this
    language and definition, we find that § 542(b) expressly protects taxpayers
    from retroactive taxation when a city puts into use any new policy,
    procedure, or interpretation of the Code that differs from a previous formal
    interpretation of the Code and is unattributable to any change in the law.
    ¶37            Section 542(b)’s express bar on retroactive taxation based on
    any changes in interpretation or application embodies the principle of fair
    notice to taxpayers. In interpreting tax statutes, we have held that such
    “statutes should provide clear notice of obligations so that taxpayers may
    comply and order their affairs accordingly.” BSI Holdings, 244 Ariz. at 22
    ¶ 25. And although privilege taxes are self-assessed, see Tucson Mech.
    Contracting, Inc. v. Ariz. Dep’t of Revenue, 
    175 Ariz. 176
    , 178 (App. 1992)
    (noting that the “liability for transaction privilege taxes
    arises automatically when a taxpayer engages in taxable business activity
    in Arizona”), they are not self-interpreted. In light of § 542’s bar on
    retroactive taxation based on a new interpretation or application not due to
    a change in the law, we see no reason not to require the same “clear notice”
    from a city to overcome that bar. Thus, when a city seeks to collect taxes on
    activities or a class of taxpayers based on a new interpretation or
    application of the Code, it cannot do so for periods before it provides notice
    —whether by public statements or communications to particular taxpayers
    —to those affected. Thus, we must decide whether the Cities adopted a
    new interpretation or application of the Code and, if so, whether the Cities
    notified the OTCs of the change.
    ¶38           Here, the OTCs have facilitated reservations at hotels in the
    Cities for over a decade, and the Cities never attempted to impose the tax
    before the 2013 Assessments. But the “continued failure to collect a tax does
    not preclude eventual taxation.” Ariz. Lotus Corp. v. City of Phoenix, 
    136 Ariz. 22
    , 24 (App. 1983) (allowing enforcement of an unambiguous tax

    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    statute despite earlier contrary administrative interpretations (citing Miami
    Copper Co. v. State Tax Comm’n, 
    121 Ariz. 150
    , 153 (App. 1978))). Thus, mere
    delinquent enforcement does not implicate § 542’s bar on retroactive
    taxation.
    ¶39            The OTCs argue that there is record evidence that at least
    some Cities, through City-issued online guidance, affirmatively indicated,
    at least by implication, that the OTCs were not taxpayers under § 444 as
    “brokers” before the 2013 Assessments because hotel industry privilege
    taxes were limited to entities that were physically located in a city and
    operated hotels. See, e.g., Hotel/Motel, Scottsdale Privilege & Use Tax
    (July 2013), available at https://web.archive.org/web/20140520230355/
    http:/www.scottsdaleaz.gov/Assets/Public+Website/taxes/HotelMotel.
    pdf (“You must be licensed and pay tax if you are located in Scottsdale and
    you operate a hotel/motel charging for lodging space furnished to any
    person.”). The OTCs contend this proves that the 2013 Assessments
    embodied a new interpretation or application of the Code concerning the
    OTCs’ status as “brokers” under § 444 because it differs from previous City-
    issued online guidance.
    ¶40           The Cities argue they have interpreted and applied the
    “brokers” policy since 2002. The Cities rely on a Private Taxpayer Ruling 7
    from 2002 in which a City of Scottsdale Tax Audit Manager, in response to
    an inquiry from an OTC, interpreted the Code in a manner consistent with
    our current interpretation of § 444, identifying the OTCs as “brokers” and
    the income they receive from markups as part of the taxable gross income.
    The Cities also rely on a 2007 letter from the City of Peoria to an OTC
    industry representative, relaying substantially the same information as the
    2002 ruling. Finally, the Cities note that the 2013 Assessments stemmed
    from a multi-jurisdictional audit, which two of the OTCs reported in their
    2008 Security Exchange Commission filings as ongoing administrative
    procedures that could result in assertions of claims against the OTCs for
    unpaid hotel occupancy taxes.
    ¶41          Unquestionably, if a city issues a private taxpayer ruling, in
    which a city official interprets and applies the Code for a taxpayer and
    7A Private Taxpayer Ruling is a public written statement of a city’s position
    interpreting the Code and applying the Code to a specific set of facts or a
    particular tax situation. MCTC § 597(k); cf. A.R.S. § 42-2101.M.1.
    17
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    provides the subject-taxpayer with clear notice, § 542(b) will not bar a city
    from assessing taxes, penalties, and interest against that taxpayer from the
    date it issued the ruling. But one city’s ruling for one taxpayer does not
    provide clear notice to all OTCs on behalf of all the Cities. Similarly, one
    city’s letter to an OTC industry representative is insufficient—even for the
    city sending the letter—to show that the impacted taxpayers (i.e., the OTCs)
    were formally notified. And the OTCs’ securities filings are evidence of no
    more than an awareness that the Cities’ audits might result in assertions of
    claims. It is possible that, as part of the Cities’ 2008 multi-jurisdictional
    audit, the Cities provided the OTCs represented in this case with official
    notices of their intent to assess taxes against the OTCs based on their status
    as “brokers,” but such evidence is not in the record currently before us.
    ¶42           In sum, there is evidence in the record that the Cities’ OTC
    “broker” position in the 2013 Assessments arguably represents a change
    from some of the Cities’ earlier online tax guidance on the issue. Supra ¶ 39.
    There is also countervailing evidence that some of the Cities may have
    notified some of the OTCs before the 2013 Assessments that the OTCs were
    taxable as “brokers.” Supra ¶ 40. We conclude that a remand is necessary
    to resolve these factual disputes as to individual cities and taxpayers.
    ¶43           The Cities and the OTCs dispute the allocation of the burden
    of proof under § 542(b). The Code is silent on this issue. Notably, § 542(b)’s
    state law counterpart, § 42-2078, imposes the burden of proving whether an
    “interpretation or application” of a tax provision is “new” on the taxpayer
    as an affirmative defense. § 42-2078(b)(3) (“The change [in interpretation
    or application] is an affirmative defense in any administrative or judicial
    action for retroactive assessment of tax, interest and penalties to taxable
    periods before the new interpretation or application was adopted.”). This
    approach accords with the long-standing approach to place the burden of
    proof on the taxpayer if the taxing statute fails to address the issue. See, e.g.,
    State Tax Comm’n v. Magma Copper Co., 
    41 Ariz. 97
    , 104 (1932). We see no
    reason to treat the Code and state tax code differently in this respect.
    ¶44            On remand, if the OTCs prove that the Cities’ 2013
    Assessments constitute a new interpretation or application of the Code
    rather than mere delayed enforcement, the Cities will bear the burden of
    proving to the tax court that they nevertheless provided the OTCs with
    clear notice of an intent to tax the OTCs under § 444 based on their status
    as “brokers.” See, e.g., Harvest v. Craig, 
    195 Ariz. 521
    , 524 ¶ 14 (App. 1999)
    18
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    Opinion of the Court
    (stating that, when a statute is silent on the issue, “the allocation of a burden
    of proof depends, inter alia, on what is fair, what is convenient, who is
    seeking to change the status quo, and policy considerations such as those
    disfavoring certain defenses”) (citing McCormick on Evidence § 337, at 432
    (4th ed. 1992)); cf. BSI Holdings, 244 Ariz. at 22 ¶ 25 (noting that “statutes
    should provide clear notice of obligations so that taxpayers may comply
    and order their affairs accordingly”).
    ¶45           Accordingly, we hold that § 542(b) bars retroactive taxation
    based on a new policy, procedure, or interpretation of the Code until such
    time that a city has adopted any such change and provided the impacted
    taxpayers with clear notice of the change.
    VI.
    ¶46           For the foregoing reasons, we vacate paragraphs 29 through
    32 of the court of appeals’ decision, as well as the portion of paragraph 33
    reversing the tax court’s conclusion “that the Cities may not assess tax,
    penalties, and interest before 2013,” and we remand to the tax court to
    determine, consistent with this Opinion, whether MCTC § 542(b) bars the
    Cities from assessing taxes, penalties, and interest due under § 444 before
    the 2013 Assessments.

    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    VICE CHIEF JUSTICE TIMMER, joined by CHIEF JUSTICE BRUTINEL, Dissenting
    TIMMER, V.C.J., joined by BRUTINEL, C.J., dissenting.
    ¶47            Section 444 of the Model City Tax Code (“MCTC”) imposes
    transaction privilege taxes on “every person engaging or continuing in the
    business of operating a hotel charging for lodging and/or lodging space.”
    Whether online travel companies (“OTCs”) are “brokers,” and therefore
    “persons” under the MCTC, or not, the dispositive issue is whether they
    engage in the business of operating hotels. The majority misinterprets § 444
    as applying to anyone “engage[d] for profit in business activities that are
    central to keeping brick-and-mortar lodging places functional or in
    operation,” including OTCs. See supra ¶¶ 18–19. In my view, § 444 has a
    narrower meaning that excludes OTCs. And because no other provision of
    the MCTC applies, the OTCs are not subject to transaction privilege taxes.
    I respectfully dissent.
    ¶48           The applicability of § 444 to OTCs depends on the meaning of
    “operating” in that provision. Because the MCTC does not define the term,
    we use its ordinary meaning. See Arizona ex rel. Brnovich v. Maricopa Cty.
    Cmty. College Dist. Bd., 
    243 Ariz. 539
    , 541 ¶ 7 (2018). “Operate” as a
    transitive verb means “to put or keep in operation” as in “operated a
    grocery store.”       Operate, Merriam-Webster, https://www.merriam-

    means “the quality or state of being functional or operative.” Operation,

    operation (last visited July 31, 2019). Thus, a person engages in the business
    of operating a hotel, and is taxed for the privilege of doing so under § 444,
    by putting a hotel into a functional or operative state or keeping it in
    operation.
    ¶49            Applying § 444’s ordinary meaning here, OTCs do not engage
    in the business of operating hotels. OTCs neither “put” hotels into a
    “functional or operative” state nor “keep” them in that state. OTCs do not
    own hotels, oversee hotel operations, or let hotel rooms. See Pitt County v.
    Hotels.com, L.P., 
    553 F.3d 308
    , 313 (4th Cir. 2009) (applying the dictionary
    definition of “operator” and “operate” and concluding that OTCs “have no
    role in the day-to-day operation or management of the hotels” and are
    therefore not “operators”); Mont. Dep’t of Revenue v. Priceline.com, Inc., 
    354 P.3d 631

    definition of ‘owners or operators.’ They do not possess, run, control,

    manage, or direct the functioning of a hotel or rental agency.”). 8 And
    hotels, which take reservations outside the OTC-process, do not depend on
    OTCs to operate their businesses. OTCs indisputably facilitate transactions
    between hotels and travelers by conveying reservation requests and
    processing payments (and any later cancellations). But these functions—
    even though important to hotels—do not transform OTCs into operators of
    hotels. Indeed, “[w]e would not say that when a hotel contracts with a
    cleaning service that orders supplies and hires, schedules, and pays
    workers, the cleaning service becomes an operator of the hotel.” Village of
    Bedford Park v. Expedia, Inc., 
    876 F.3d 296
    , 304 (7th Cir. 2017) (applying the
    ordinary meaning of “operator”).
    ¶50          The majority accepts the above-cited definitions but is
    persuaded to give § 444 a more expansive meaning in light of MCTC § 447,
    which provides:
    In addition to the taxes levied as provided in [§ 444], there is hereby
    levied and shall be collected an additional tax in an amount equal to
    ___ percent (___%) of the gross income from the business activity of
    any hotel engaging or continuing within the City in the business of
    charging for lodging and/or lodging space furnished to any
    transient.
    According to the majority, because the MCTC drafters “used specific
    language to limit the additional tax liability of § 447 to the gross income of
    ‘hotels,’” and chose not to do so in § 444, the drafters must have intended
    that “the tax liability of § 444 extends beyond the hotels’ owners and
    operators.” See supra ¶ 16. It then concludes that § 444 broadly applies to
    anyone who “engages for profit in business activities that are central to
    keeping brick-and-mortar lodging places functional or in operation.” See
    supra ¶ 18. I disagree for several reasons.
    8The majority dismisses these cases because the statutes at issue applied to
    “operators” (Pitt County) and “owners or operators” (Mont. Dep’t of
    Revenue) while § 444 applies to persons engaged in “the business of
    operating a hotel.” See supra ¶ 15. This razor-thin semantic distinction is
    meaningless. Both cases gave plain meaning to what it means to “operate”
    a hotel, which is the issue here. Regardless, I rely primarily on the same
    dictionary definitions of “operate” and “operation” used by the majority.
    See supra ¶ 18.

    ¶51           First, the majority misapprehends § 447, which leads it to
    misinterpret § 444. Section 447 does not identify the taxpayer as “hotel
    owners and operators” by referring to “any hotel,” as the majority asserts.
    See supra ¶ 17. “Any hotel” does not identify the taxpayer but instead
    describes, in part, the calculation for the additional tax. See MCTC § 447
    (setting the tax as a percentage of “the gross income from the business
    activity of any hotel”). A brick-and-mortar hotel is not a taxpayer; only
    individuals and entities are taxpayers. See MCTC § 100 (defining
    “taxpayer” as “any person” liable for privilege taxes and defining “person”
    as individuals, legal entities, and government); see also MCTC § 300
    (confining transaction privilege and use tax licensing requirements to
    “person[s]”).
    ¶52           The taxpayer required to pay the additional tax required by §
    447 is the same taxpayer identified in § 444— “every person engaging or
    continuing in the business of operating a hotel.” No other taxpayer is
    identified in § 447. By providing that the taxes are “[i]n addition to” the
    taxes levied by § 444, the provision is most reasonably interpreted as
    imposing additional taxes on the taxpayer identified in § 444. This
    interpretation is further supported by considering that § 447 is an optional
    “add on” for cities to impose additional taxes on hotel revenues that can be
    dedicated to specific uses. See MCTC § 447. For example, the City of
    Scottsdale imposes a 1.75% tax under § 444 to defray general city expenses
    and imposes a 5% tax under § 447 to be used for tourism-related purposes.
    See Scottsdale Revised Code, Appendix C, Transaction Privilege & Use Tax
    Code, §§ 300, 444, 447. Also, although § 447 does not repeat § 444’s tax
    exclusions, the Arizona Department of Revenue applies those exclusions to
    § 447 taxes, thereby demonstrating the department’s view that § 447 is an
    “add on” to § 444. See Arizona Tax Matrix for Hotel/Motel Lodging Industry,
    Ariz.      Dep’t        of     Revenue        Tax        Ruling       TPR 06-1,
    https://azdor.gov/sites/default/files/RULINGS_TPT_2006_tpr06-1-
    matrix.pdf. (“TPR 06-1”) (applying §§ 444 and 447 taxes to the same
    revenue sources); see also Scottsdale Healthcare, Inc. v. Ariz. Health Care Cost
    Containment Sys. Admin., 
    206 Ariz. 1
    , 8 ¶ 27 (2003) (noting that agency
    interpretation of a statute is given weight). Finally, this interpretation of
    § 447 aligns with all other MCTC privilege tax categories, which impose tax
    liability on persons or entities “engaging or continuing in” particular
    businesses. See MCTC art. IV.
    22
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    VICE CHIEF JUSTICE TIMMER, joined by CHIEF JUSTICE BRUTINEL, Dissenting
    ¶53          In sum, the same taxpayers are liable for taxes imposed by §§
    444 and 447. The majority therefore errs by concluding that §§ 444 and 447
    apply to different taxpayers and then defining the § 444 taxpayer more
    expansively in a misguided attempt to distinguish § 447.
    ¶54            Second, by interpreting § 444 as taxing the gross income of
    anyone who “engages for profit in business activities that are central to
    keeping brick-and-mortar lodging places functional or in operation,” then
    sweeping OTCs into that category, the majority necessarily imposes the tax
    on persons and entities no reasonable person would conclude engage in
    “the business of operating a hotel.”          For example, as the Cities
    acknowledged at oral argument here, the majority’s interpretation means
    airlines, credit card companies, brick-and-mortar travel agents, and others
    who offer hotel booking services for a profit and accept payments directly
    from customers also “operat[e] hotels” and must now secure privilege tax
    licenses and pay taxes in every city in which they book hotel rooms and
    collect payment directly from customers. The majority agrees. It points out
    that hotels currently pay taxes on the full amount paid directly to them by
    customers, even though some portions are later remitted to brick-and-
    mortar travel agents and credit card companies (e.g., American Express
    Travel) as service fees. See supra ¶ 21. That is also what occurs when
    customers directly pay hotels in full upon arrival for an OTC-booked room
    and amounts are remitted to OTCs. But although hotels remit taxes on
    customer payments representing OTCs and brick-and-mortar travel agents’
    fees and commissions—not an issue here—agents and credit card companies
    have not paid privilege taxes when they have directly collected their fees
    and commissions from customers when booking. The opinion today
    changes the status quo and requires these agents, credit card companies,
    and others to secure licenses and pay municipal taxes for the privilege of
    “operating hotels.”
    ¶55            The majority’s broad interpretation also means that third-
    party entities who provide maintenance, housekeeping, gardening and like
    “central” services to hotels are now also subject to taxation under § 444—
    surely an unintended result under the MCTC. The majority attempts to
    side-step this result by limiting “central” services to those “essential” to
    furnish lodging, presumably reservations, payment processing, and front-
    desk operations, and then concluding that services like housekeeping do
    23
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL
    VICE CHIEF JUSTICE TIMMER, joined by CHIEF JUSTICE BRUTINEL, Dissenting
    not fit within that definition. 9 See supra ¶¶ 18, 21. My colleagues in the
    majority would presumably (and hopefully) consider the fresh sheets
    placed by housekeeping on their hotel room beds to be “essential” to their
    lodging. Regardless, the MCTC provides that “lodging” includes not just a
    hotel room but “the furnishings or services and accommodations”
    accompanying it, meaning § 444 applies to a broader category of business
    activity than the majority credits. See MCTC § 100 (defining “lodging”).
    Indeed, the Arizona Department of Revenue maintains that items such as
    onsite childcare and hotel-arranged transportation are taxable under § 444.
    See TPR 06-1.
    ¶56            Third, at a minimum, § 444’s applicability, when considered
    in context with § 447, creates an ambiguity about the identity of the
    taxpayer subject to § 444. Ambiguities in tax provisions are construed
    “liberally in favor of the taxpayer and strictly against the state.” See Ebasco
    Servs. Inc. v. Ariz. State Tax Comm’n, 
    105 Ariz. 94
    , 97 (1969); see also City of
    Peoria v. Brink’s Home Sec., Inc., 
    226 Ariz. 332
    , 333 ¶ 6 (2011) (“We read tax
    provisions ‘to gain their fair meaning, but not to gather new objects of
    taxation by strained construction or implication.’” (quoting Ariz. State Tax
    Comm’n v. Staggs Realty Corp., 
    85 Ariz. 294
    , 297 (1959))). This principle
    further confirms that § 444 applies no more broadly than does § 447.
    ¶57            The majority is also persuaded to apply § 444 to OTCs because
    otherwise “illogical and unjustifiable tax consequences” would occur
    depending on whether an OTC-customer directly paid a hotel (paying more
    tax) or paid the OTC (paying less tax). See supra ¶ 26. But a municipal
    privilege tax is an excise tax on the privilege of doing business; it is not a
    sales tax on customer transactions. See Ariz. Dep’t of Revenue v. Mountain
    States Tel. & Tel. Co., 
    113 Ariz. 467
    , 468 (1976) (noting that a state privilege
    tax “is an excise tax on the privilege or right to engage in an occupation or
    business in the State of Arizona”). Thus, it is not “illogical or unjustifiable”
    to tax only the gross income of persons privileged to operate hotels in the
    taxing cities rather than tax the total amount paid by the hotel guest. Any
    inequity—a windfall to the cities or a disadvantage to the hotel operators—
    9
    The majority also asserts that such entities are distinguishable because
    they are not “brokers.” See supra ¶ 21. That is irrelevant. Third-party
    companies that provide housekeeping and the like are “persons” under the
    MCTC and thus subject to taxation under § 444 if they engage in the
    operation of hotels.
    24
    CITY OF PHOENIX ET AL V. ORBITZ WORLDWIDE, INC. ET AL

    is a matter of policy that should be left to the MCTC drafters, not this Court.
    Cf. Pitt County, 
    553 F.3d at 314
     (the potential for a tax loophole “does not
    compel a broader interpretation” of the code’s language); Louisville/Jefferson
    Cty. Metro Gov’t v. Hotels.com, L.P.,

    (refusing to entertain loophole hypotheticals and pointing out that the
    legislature, “not the court, is the proper entity to close any such potential
    loophole.”). In fact, after the imposition of the taxes at issue here, the
    legislature addressed taxation of persons and entities engaging in “the
    business of operating an online lodging marketplace.” See A.R.S. § 42-
    5076(A); see also A.R.S. § 42-6009 (delineating circumstances in which a city
    can tax an online lodging marketplace).
    ¶58           For these reasons, I disagree with the majority’s interpretation
    of § 444 and its application to OTCs. Because § 447 is also inapplicable to
    OTCs, I would reverse the tax court’s judgment and remand for entry of
    judgment in the OTCs’ favor. I respectfully dissent.
