This action involves the right of the state to impose and collect a sales tax on water furnished by the City of Phoenix to its patrons and customers. The action was brought on the relation of the attorney general to settle a controversy between the State Tax Commission, whose duty it is to collect sales taxes, and the city authorities as to whether the latter is subject to the tax, and therefore seeks to secure a declaratory judgment construing "The Excise Revenue Act of 1935" (Chapter 77, as amended by Chapter 2, First Special Session, Laws of 1937). The trial court upheld the state's right to impose and collect the tax, and the city has appealed.
No claim is made that the city is not within the language of the statute designating those who are liable for the tax, but it is insisted that certain provisions of *Page 31 the Constitution make the imposition of the tax on municipalities beyond the power of the legislature. Those provisions are section 34, article 2, and section 5, article 13, and read:
"Section 34. The State of Arizona and each municipal corporation within the State of Arizona shall have the right to engage in industrial pursuits."
"Section 5. Every municipal corporation within this State shall have the right to engage in any business or enterprise which may be engaged in by a person, firm, or corporation by virtue of a franchise from said municipal corporation."
[1, 2] There is nothing in these sections of the Constitution indicating an intention to exempt municipalities that engage in an industrial pursuit, business, or enterprise from paying a tax on their products, or income, or service. It would seem that when municipalities become competitors with private enterprise they should be treated no better than others operating in the same field. The general rule is that municipalities are subject to the same liabilities as private corporations, or individuals, except when they are exercising purely governmental functions. Sumid v. City of Prescott, 27 Ariz. 111, 230 P. 1103; City ofTuscon v. Sims, 39 Ariz. 168, 4 P.2d 673.
[3-5] Chapter 77 and amendment require a taxpayer to obtain a license before commencing business (section 11), and it is objected that such a restriction cannot be made to apply to municipalities. The purpose of requiring this license is that the tax commission may know who are in business and should pay the tax. Giragi v. Moore, 49 Ariz. 74, 64 P.2d 819, 110 A.L.R. 320. The penalty prescribed (in section 11) for a failure to pay the tax (imprisonment) is not essential to its validity. Neither chapter 77 as amended nor the criminal laws of the state provide for the incarceration of the officers of a municipality *Page 32 for failure to pay the license or the tax. State v. BoiseCity, 57 Idaho 507, 66 P.2d 1016; State v. Board ofCounty Commrs. of Barton County, 142 Kan. 624, 51 P.2d 33. We see no reason for a municipality's civil liability being different from others.
[6] The law does not require the city to pay a tax on water furnished itself in the discharge of its governmental functions, such as affording fire and health protection and sanitation, but only when it is furnishing its patrons water for commercial or domestic use. Section 12, article 9 of the Constitution empowers the legislature "to provide for the levy and collection of license . . . gross revenue, excise, income . . . taxes . . . or other specific taxes" and this applies to municipalities engaged in a business or enterprise the same as to a private person so engaged.
There are many courts holding that sales tax laws are applicable to sales of gasoline by cities and counties and that such municipalities should pay the tax the same as other dealers in that commodity. Some of these cases are: State v. BoiseCity, supra; Orange State Oil Co. v. Amos, 100 Fla. 884,130 So. 707; City of Covington v. State Tax Com., 257 Ky. 84,77 S.W.2d 386; People v. Deep Rock Oil Corp., 343 Ill. 388,175 N.E. 572; City of Ardmore v. State ex rel. Oklahoma TaxCom., 168 Okla. 316, 32 P.2d 728; State v. Board ofCounty Commrs. of Barton County, supra; People v. City andCounty of Denver, 84 Colo. 576, 272 P. 629; Crockett v.Salt Lake County, 72 Utah 337, 270 P. 142, 60 A.L.R. 867;City of Portland v. Kozer, 108 Or. 375, 217 P. 833; State v. City of Monroe, 177 La. 983, 149 So. 541; City of FortSmith v. Watson, 187 Ark. 830, 62 S.W.2d 965; City ofJackson v. State, 156 Miss. 306, 126 So. 2; City ofGreenville v. Query, 166 S.C. 281, 164 S.E. 844; affirmed286 U.S. 472, 52 Sup. Ct. 631, 76 L. Ed. 1232, 84 A.L.R. 831; State v. *Page 33 Woodbury County, 222 Iowa 488, 269 N.W. 449; State v.Cheyenne County, 127 Neb. 619, 256 N.W. 67; State v. City ofSioux Falls, 60 S.D. 330, 244 N.W. 365; City of Birmingham v.State, 233 Ala. 138, 170 So. 64.
[7, 8] The sales tax is an excise and not a property tax (White v. Moore, 46 Ariz. 48, 46 P.2d 1077), and its imposition is not prohibited by section 2, article 9, providing: "That there shall be exempt from taxation all Federal, State, county and municipal property." Stults Eagle Drug Co. v. StateTax Com., 48 Ariz. 467, 62 P.2d 1126. The tax referred to in this constitutional provision is a property tax and not an excise tax.
[9, 10] It is argued that the court will take judicial notice that the water supply of the City of Phoenix is appropriated water from the underflow of the Verde River and therefore not subject to ownership or sale by the city. It is a recognized principle that public water, or water subject to appropriation under our laws, does not belong to the appropriator in the sense that he may do with it what he pleases or what the owner of property may generally do. But it is also recognized that theuse of such water is subject to ownership and sale. Brewster v. Salt River Valley Water Users' Assn., 27 Ariz. 23,229 P. 929. If the city cannot dispose of the water by furnishing it to its patrons or consumers, then it cannot make the appropriation for that is the major reason for the appropriation. Its appropriation is valid and it can certainly sell its use for all or any purposes to which it may lawfully be put.
[11] It is next argued that it is an unconstitutional classification to require municipalities to pay a sales tax and not to require irrigation districts, which are quasi-public corporations, to pay a tax upon water *Page 34 furnished its consumers. We said in White v. Moore, supra:
"It must be kept in mind that a privilege tax is not a tax on property but a tax on the right to engage in business and that the Legislature may impose it on any class or classes of business it cares to and decline to apply it to others, its only limitation in this respect being that the classification it makes must be reasonable, not arbitrary or discriminatory, and such that all those falling within the same class will be treated alike."
It is apparent there is quite a difference between a municipality operating a water system for its patrons and customers and an irrigation district organized to furnish irrigation water to farmers to cultivate and grow food for man and animal, and we cannot say that the legislative classification is arbitrary or unreasonable, or not founded upon a substantial difference in the two kinds of corporations and their business.
[12] We are of the opinion that the law requiring the City of Phoenix to pay the sales tax is valid, and that the judgment of the lower court should be affirmed.
