opinion: Mr. Chief Justice Warren
  delivered the opinion of the Court.
  In this case, among other issues which we need not reach, we are asked to decide whether a Texas tax statute, Article 5248 of the Revised Civil Statutes of Texas, as amended in 1950, discriminates unconstitutionally against the United States and those with whom it deals. We hold that it does.
  Appellant, Phillips Chemical Company, engages in the commercial manufacture of ammonia on valuable industrial property leased from the Federal Government in Moore County, Texas. The lease, executed in 1948 pursuant to the Military Leasing Act of 1947, 61 Stat. 774, is for a primary term of 15 years and calls for an annual rental of over $1,000,000. However, it reserves to the Government the right to terminate upon 30 days’ notice in the event of a national emergency and upon 90 days’ notice in the event of a sale of the property.
  In 1954, appellee, Dumas Independent School District, assessed a tax against Phillips for the years 1949 through 1954. The tax, measured by the estimated full value of the leased premises, was assessed in accordance with the District’s ordinary ad valorem tax procedures.
  When the District assessed the tax, Phillips commenced the present action in the state courts to enjoin its collection. Phillips contested both the District’s right to levy the tax and the valuation figure upon which the amount of the tax was calculated. The latter issue was severed by the trial court for later decision and is not involved in this appeal. The lower state courts denied relief for the years subsequent to the effective date of the 1950 amendment to Article 5248, and on writ of error the Supreme Court of Texas, by a divided court, affirmed. 159 Tex. -, 316 S. W. 2d 382. Phillips appealed from the decision, and we noted probable, jurisdiction. 359 U. S. 987.
  The District’s power to levy the tax was found to lie in amended Article 5248. Before 1950, Article 5248 provided a general tax exemption for land and improvements “held, owned, used and occupied by the United States” for public purposes. In 1950, the Texas Legislature added two provisions to Article 5248, one providing for taxation of privately owned-personal property located on federal lands, and the other reading as follows:
  “[Pjrovided, further, that any portion of said lands and improvements which is used and occupied by any person, firm, association of persons or corporation in its private capacity, or which is being used or occupied in the conduct of any private business or enterprise, shall be subject to taxation by this State and its political subdivisions.”
  As construed by a majority of the Texas court, this provision is an affirmative grant of authority to the State and its political subdivisions to tax private users of government realty. While the subject ci the tax is the right to the use of the property, i. e., the leasehold, its measure is apparently the value of the fee. The constitutionality of the provision, thus construed, depended upon the court’s interpretation of our decisions in the Michigan cases two Terms ago, where we held that a State might levy a tax on the private use of government property,, measured by the full value of the property. . United States v. City of Detroit, 355 U. S. 466; United States v. Township of Muskegon, 355 U. S. 484; cf. City of Detroit v. Murray Corp., 355 U. S. 489.
  However, three members of the Texas court, joined by a fourth on petition for rehearing, were of the opinion that under the majority’s construction the statute discriminates unconstitutionally against the United States and its lessees. Their conclusion rested on the fact that Article 7173 of the Revised Civil Statutes of Texas imposes a distinctly lesser burden on similarly situated lessees of exempt property owned by the State and its political subdivisions. We agree with the dissenters’ conclusion.
  Article 7173 is the only Texas statute other than Article 5248 which authorizes a tax on lessees. It provides in-part that:
  “Property held under a lease for a term of three years or more, or held under a contract for the purchase thereof, belonging to this State, or that is exempt by law from taxation in the hands of- the owner thereof, shall be considered for all the purposes of taxation, as the property of the person so holding the same, except as otherwise specially provided by law.”
  As construed by the Texas courts, Article 7173 is less burdensome than Article 5248 in three respects. First, the measure of a tax under Article 7173 is not the full value of leased tax-exempt premises, as it apparently is under Article 5248, but only the price the taxable lease-, hold would bring at a fair voluntary sale for cash — the value of the leasehold itself. Second, by its very terms, Article 7173 imposes no tax on a lessee whose lease is for a term of less than three years. Finally, and crucial here, a lease for three years or longer but subject — like-Phillips^ — to. termination at the lessor’s option in the event of a sale is not “a lease for a term of three years or moré” for purposes of Article 7173. Trammell v. Faught, 74 Tex. 557, 12 S. W. 317. Therefore, because of the termination provisions in its lease, Phillips could not be taxed under Article 7173.
  Although Article 7173 is, in terms, applicable to all lessees who hold tax-exempt property under a lease for a term of three years or more, it appears that only lessees of public property fall within this class in Texas. Tax exemptions for real property owned by private organizations — charities, churches, and similar entities — do not survive a lease to a business lessee. The full value of the leased property becomes taxable to the owner, and the lessee’s indirect burden consequently is as heavy as the burden imposed directly on federal lessees by Article 5248. Under these circumstances, there appears to be no discrimination between the Government’s lessees and lessees of private property.
  However, all lessees of exempt public lands would appear to belong to the class defined by Article 7173. In view of the fact that lessees in this class are taxed because they use exempt property for a nonexempt purpose, they appear to be similarly situated and presumably should be taxed alike. Yet by the amendment of Article 5248, the Texas Legislature segregated federal lessees and imposed on them a heavier tax burden than is imposed on the other members of the class by Article 7173. In this case the resulting difference in tax, attendant upon the identity of Phillips’ lessor, is extreme; the State and the School District concede that Phillips would not be taxed at all if its. lessor were the State or one of its political subdivisions. instead of the Federal Government. The discrimination against the United States and its lessee seems apparent. The question, however, is whether it can be justified.
  Phillips argues that because Article 5248 applies only to private users of federal property, it is invalid for that reason, without more. For this argument, it relies on Miller v. Milwaukee, 272 U. S. 713; see also Macallen.Co. v. Massachusetts, 279 U. S. 620. Macollen might be deemed to support the argument, but to the extent that it dóes, it no longer has precedential value. See United States v. City of Detroit, supra, at 472, n. 2. Miller was a rather, different case. In Miller it was thought that a State had attempted indirectly to levy a tax on exempt .income from government bonds. Phillips’ use of the Government’s property, by way of contrast, is not exempt. 10 U. S. C. § 2667 (e); United States v. City of Detroit, supra: It is true that in Miller the ostensible incidence of the tax — shareholders’ income from corporate dividends — was not itself exempt, but the measure of the tax excluded all income not attributable to federal bonds owned by the corporation; that was the defect in the tax. See Pacific Co. v. Johnson, 285 U. S. 480, 493. Therefore, in practical operation, the tax was either an indirect tax on the exempt income, ór a discriminatory tax on shareholders of corporations which, as bondholders, dealt with the Government. Thus, if Miller has any relevance here, it is only to the extent that it may support the proposition that a State may not single out those who deal with the Government, in one capacity or another,, for a tax burden not imposed on others similarly situated.
  A determination that Article 5248 is invalid, under this test, cannot rest merely on an examination of that article. It does not operate in a vacuum. First, it is necessary to determine how other taxpayers similarly situated are treated. Such a determination requires “an examination of the whole tax structure of the state.” Cf. Tradesmens National Bank v. Oklahoma Tax Comm’n, 309 U. S. 560, 568. Although Macollen may have departed somewhat from this rule, nothing in Miller, at least as it has been interpreted in later cases,' should be read as indicating that less is required. Cf. Educational Films Corp. v. Ward, 282 U. S. 379; Pacific Co. v. Johnson, 285 U. S. 480.
  Therefore, we must focus on the nature of the classification erected by Articles 5248 and 7173. The imposition of a heavier tax burden on lessees of federal property than is imposed on lessees of other exempt public property must be justified by significant differences between the two classes: The School District addresses.this problem, essentially, as-one of equal protection, and argues that we must uphold the classification, though apparently discriminatory, “if any state of facts reasonably can be conceived that would sustain it.” Allied Stores v. Bowers, 358 U. S. 522, 528. The argument, in this context, turns on three supposed differences between the two classes. First, the School District and the State say that the State can collect in rent what it loses in taxes from its own lessees — something it cannot do, of course, with the Federal Government’s lessees. Second, they argue that the State may legitimately ■ foster its own interests by adopting measures which facilitate the leasing of its property. Finally, they claim that because of its allegedly greater magnitude, federal leasing of exempt land has a more serious impact on the finances and operations of local government than does the State’s own leasing activities.
  None of these considerations provides solid support for the classification. It is- undoubtedly true, as a general proposition, that the State is free to adopt measures reasonably designed to facilitate the leasing of its own land. But if the incentive which it provides is in the form of a reduction in tax which discriminates against the Gov- ' ernment’s lessees, the question remains, is it permissible?
  Likewise, it is not enough to say that the State can make up in' rent what it loses in taxes from its lessees. What the State’s political subdivisions lose in taxes from the State’s lessees cannot be made up in this fashion. Other local taxpayers — including the Government’s lessees — must make up the difference.
  Nor is the classification here supported by the allegedly serious impact of federal leasing, as contrasted with state leasing, on the operations of local government. .It is claimed, in this respect, that neither the State nor its subdivisions lease property exactly comparable — in size, value, or number of employees involved — to the ordnance works leased by Phillips from the Government. However, the classification erected by Article 5248 is not based on such factors. Article 5248 imposes its burdens on atl lessees of federal property. It is conceded that the State and its subdivisions lease valuable property to commercial and business enterprises, as does the Federal Government. Warehouse facilities are an example.- But the identity of the exempt lessor bears no relation to the impact on local government of otherwise identical leasing activities. Still, the variant tax consequences to the lessee, under Article 7173 on the one hand and Article 5248 on the other, differ, widely.
  It is true that perfection is by no means required under the equal protection test of permissible classification.. But we have made it clear, in the equal protection cases, that our decisions in that field are not necessarily controlling where problems of intergovernmental tax immunity are involved. In Allied Stores v. Bowers, supra, for example, we noted that the State was “dealing with [its] proper domestic concerns, and not trenching upon the prerogatives of the National Government.” 358 U. S., at 526. When such is the-case, the State’s power to classify is,' indeed, extremely broad, and its discretion is limited only by constitutional rights and by the doctrine that a classification may not be palpably arbitrary. Id., at 526-528. But where taxation of the private use of the Government’s property is concerned, the Government’s interests must be weighed in the balance. Accordingly, it does not seem toó much to require that the State treat those who deal with the Government as well as it treats those with whom it deals itself. Compare Esso Standard Oil Co. v. Evans, 345 U. S. 495, 500.
  Nevertheless, it is claimed that the classification here is supported by our decision in United States v. City of Detroit, supra, because of the assertedly similar nature of the classification created by the statute involved in that case. The Michigan statute, although applicable generally to lessees of exempt property, contained an exception for property owned by state-supported educational institutions. Appellee’S argument, essentially, is that the exemption of lessees of- school-owned property from the Michigan statute supports the imposition here of a heavier tax on federal lessees than is imposed on lessees of other exempt public property, in general.
  This argument misconceives the scope of the Michigan decisions. In those cases we did not decide — in fact, we were not asked to decide — whether the exemption of school-owned property rendered the statute discriminatory. Neither the Government nor its lessees, to whom the statute was applicable, claimed discrimination of this character. Since the issue was not ráised, the basis for the separate classification of property owned by schools was not examined. Therefore, the Michigan cases shed no light on the classification problem here.
  None of these arguments, urged in support of the Texas classification, seems adequate to justify what appears to be so substantial and transparent a discrimination against the Government and its lessees. Here, Phillips is taxed under Article 5248 on the full value of the real property which it leases from the Federal Government, while businesses with similar leases, using exempt property .owned by the State and its political subdivisions, are not taxed on their leaseholds at all. The differences between the two classes, at least when the Government’s interests are weighed in the balance, seem too impalpable to warrant such a gross differentiation. It follows that Article 5248, as applied in this case, discriminates unconstitutionally against the United States and its lessee. As we had occasion to state, quite recently, it still remains true, as it has from the time of M’Culloch v. Maryland, 4 Wheat. 316, that a state tax may not discriminate against the Government or those with whom it deals. See United States v. City of Detroit, supra, at 473. Therefore, this tax may not be exacted.
  Reversed.
  Mr. Justice Frankfurter concurs in the result.

  The Court of Civil Appeals thought that the tax should be limited to the value of Phillips’ leasehold, 307 S. W. 2d 605, 609, while the Texas Supreme Court expressed the view indicated above. However, as the State points out, these statements in the opinions of the two appellate courts were apparently dicta, for the trial court decided only the bare question of taxability, reserving for later a decision on the measure and amount of the tax. The measure of the tax, however, is not presently critical, for, as will be indicated, the levy of any tax in the circumstances of this case appears to discriminate against the Government and Phillips.

  Although public lands in general are exempt from state and local taxation in Texas, Tex. Const., Art. XI, § 9; Vernon’s Tex. Rev. Civ. Stat., 1948, Art. 7150 (4), there are certain conditions and exceptions to the exemption. The exemption does not survive a lease if the “public purpose” of the property is abandoned. Abilene v. State, 113 S. W. 2d 631 (Tex. Civ. App.); State v. Beaumont, 161 S. W. 2d 344 (Tex. Civ. App.). The School District concedes that this condition is met in this case because the lease reserves to the United States the right to terminate in the event of a national emergency. Exceptions to the general exemption of land owned by the State and its political subdivisions are created by statutes expressly providing for the taxation of certain types of public property by specific taxing authorities. E. g., school-owned agricultural and grazing land is subject to local taxation, Tex. Const., Art. VII, § 6a; Vernon’s Tex. Rev. Civ. Stat., 1948, Art. 7150a; state farms on which convict labor is employed are subject to county and school taxation, Vernon’s Tex. Rev. Civ. Stat., 1948, Art. 7150 (4); prison property is subject to school taxation, Vernon’s Tex. Rev. Civ. Stat., 1948, Arts. 7150 (17) and (18); and land which forms a part of the endowment of the University of Texas is subject to county taxation, Vernon’s Tex. Rev. Civ. Stat., 1948, Art. 7150c. Although these exceptions to the general nontaxability of public lands reduce th,e extent of the discrimination created by Article 5248, they obviously do not eliminate it.
  During the years in question, the leasehold was taxable under § 6 of the Military Leasing Act of 1947, 61 Stat. 774, the predecessor • of the provision now codified as 10 U. S. C. § 2667 (e). Section 6 provided in part that “[tjhe lessee’s interest, made or created pursuant to the provisions of this Act, shall be made subject to State or local taxation.”

  In its brief, the Government stated that the exception was not pertinent to its argument. Its- discrimination argument rested on the proposition that the Michigan, statute was, in reality, “special legislation” directed at government property. The Government argued that this purpose was manifested by the fact that the statute contained an exception for cases in which payments had been, made by the United States “in lieu of taxes in amounts equivalent to taxes which might otherwise be lawfully assessed.” It was argued that the purpose thus manifested was improper under Macallen Co. v. Massachusetts, supra. We pointed out, in rejecting the argument, that the exception to the tax relied on by the Government in this connection served to protect it against thé possibility of a double contribution to the revenues of the State, and that the precedential value of Macollen had been substantially impaired by later decisions. See United States v. City of Detroit, supra, at 472, n. 2, 474, n. 6.
