delivered the opinion of the Court.
Regulation 25 of the Mississippi State Tax Commission requires out-of-state liquor distillers and suppliers to collect from military installations within Mississippi, and remit to the Commission, a tax in the form of a wholesale markup of 17% to 20% on liquor sold to the installations. 1 The United States has four military in *601 stallations in the State. Exclusive federal jurisdiction is exercised over two of the installations, Keesler Air Force Base and the Naval Construction Battalion Center. 2 The United States and Mississippi exercise concurrent jurisdiction over the other two installations, Columbus Air Force Base and Meridian Naval Air Station. The issue presented on this appeal is whether Regulation 25 imposes an unconstitutional state tax upon these federal instrumentalities.
I
The controversy between the United States and the Tax Commission over Regulation 25 is here for the sec
*602
ond time. Shortly after adoption of the Regulation, the United States asserted before the Commission that the markup was unconstitutional as a tax upon federal instrumentalities, and proposed an escrow account for the amount of the tax pending a judicial determination of its legality. The Commission refused and advised out-of-state distillers by letter that the markup “must be invoiced to the Military and collected directly from the Military . . .” or the distillers would face criminal prosecution and delistment of their authority to sell liquor in Mississippi. The United States thereupon paid the markup under protest and brought this action in the District Court for the Southern District of Mississippi. The complaint sought a declaratory judgment that Regulation 25 imposed an unconstitutional tax on federal instrumentalities, an injunction against its enforcement, and a refund of the sums paid under protest.

The Tax Commission moved for summary judgment. A three-judge District Court granted the Commission’s motion.
There were, however, other issues addressed to Regulation 25 that had not been reached by the District Court. We therefore remanded the case for that court’s initial consideration and determination of the issues. In respect to the two exclusively federal enclaves, the Tax Commission argued that the markup might properly be viewed as a sales tax, and that the United States had consented to the imposition of such a “tax” under the Buck Act of 1940, now 4 U. S. C. §§ 105-110. Section 105 (a) provides that no person may be relieved of any sales or use tax levied by a State on the ground that the sale or use occurred in whole or part within a federal area. But § 107 (a) provides that § 105 (a) “shall not be deemed to authorize the levy or collection of any tax on or from the United States or any instrumentality thereof . . . .” We directed that, upon remand, the District Court address and determine the questions whether the markup should be treated as a tax on sales occurring within a federal area within the meaning of § 105 (a), and, if so, whether the exception contained in § 107 (a) nevertheless preserves the federal immunity with respect to transactions with nonappropriated fund activities on the two exclusively federal enclaves.
*604
The Buck Act questions are irrelevant to the markup as applied to the two concurrent jurisdiction bases, and, therefore, the United States argued that the markup is a tax upon instrumentalities of the United States that is unconstitutional under
McCulloch
v.
Maryland,
II
On the remand the District Court held, as to the exclusively federal enclaves, that the markup constituted a “sales or use tax” within the meaning of § 105 (a) of the Buck Act, and that the exception in § 107 (a) for taxes upon federal instrumentalities was inapplicable because Regulation 25 imposes the legal incidence of the tax upon the distillers, and not upon any federal instrumentality,
III
The exception in § 107 (a) is plainly a congressional preservation of federal immunity from any state tax that *605 would violate the principle of McCulloch v. Maryland, supra, prohibiting state taxation of instrumentalities of the United States. If Regulation 25 is invalid under that principle, it is invalid in its imposition of the markup upon all out-of-state purchases, both those destined for the nonappropriated fund activities on the exclusive jurisdiction bases, and those destined for those activities on the concurrent jurisdiction bases. We therefore turn to our reasons for concluding that Regulation 25 is an unconstitutional tax upon instrumentalities of the United States.
Before 1966, Mississippi prohibited the sale or possession of alcoholic beverages within its borders. In that year, however, the state legislature enacted the “Local Option Alcoholic Beverage Control Law,” Miss. Code Ann. § 67-1-1 et seq., which created the State Tax Commission as the sole importer and wholesaler of alcoholic beverages, not including malt liquor, in the State, Miss. Code Ann. § 67-1-41. The statute authorized the Tax Commission to purchase intoxicating liquors and sell them “to authorized retailers within the state including, at the discretion of the commission, any retail distributors operating within any military post . . . within the boundaries of the state, . . . exercising such control over the distribution of alcoholic beverages as seem[s] right and proper in keeping with the provisions and purposes of this chapter.” Ibid. The legislature also directed the Commission to add to the cost of all alcoholic beverages a price markup designed to cover the cost of operation of the wholesale liquor business, yield a reasonable profit, and keep Mississippi’s liquor prices competitive with those of neighboring States, Miss. Code Ann. § 27-71-11. Generally, the wholesale markup was 17% on distilled spirits and 20% on wine.
Pursuant to its statutory authority the Commission *606 promulgated Regulation 25 which gave post exchanges, officers’ clubs, ship’s stores, and other nonappropriated fund activities operating on military installations within Mississippi the option of purchasing alcoholic beverages directly from out-of-state distillers or from the Commission. The Regulation requires that orders from distillers bear the usual price markup as charged by the Commission on its sales, which the distiller in turn must remit to the Commission or face a fine, imprisonment, or delisting, i. e., withdrawal of the privilege of distributing alcoholic beverages to the Commission for resale in Mississippi. See, e. g., Miss. Code Ann. § 27-71-23. The various nonappropriated fund activities at the four military installations in Mississippi all chose to purchase their alcoholic beverages directly from out-of-state distillers, and thereby continued the practice begun when Mississippi was a “dry” State.
The District Court correctly determined that post exchanges and similar facilities are instrumentalities of the United States: “it is clear that the ship’s stores, officers’ clubs and post exchanges ‘as now operated are arms of the government deemed by it essential for the performance of governmental functions . . . and partake of whatever immunities it may have under the constitution and federal statutes.’ ”
In determining that the legal incidence of the Mississippi wholesale markup fell not upon the Federal Government but upon the out-of-state distillers, the District Court defined legal incidence as “the legally enforceable, unavoidable liability for nonpayment of the tax.”
Ibid.
That was error. The Tax Commission, of course, has not attempted to collect the markup directly from the nonappropriated fund activities, but has instead compelled out-of-state suppliers to collect the markup for it. But that fact alone is not determinative that the markup is a tax on the suppliers rather than on the instrumentalities of the United States. In
First Agricultural Nat. Bank
v.
Tax Comm’n,
We see no difference between this markup and a sales tax which must be collected by the seller and remitted to the State. The Tax Commission would distinguish
First Agricultural Nat. Bank
on the ground that because the immunity of the national bank from state taxation in all but a few closely defined areas was conferred by statute, c. 267, 42 Stat. 1499, as amended, 12 U. S. C. § 548, the Court did not decide “the constitutional question of whether today national banks should be considered nontaxable as federal instrumentalities.”
*610
Kern-Limerick, Inc.
v.
Scurlock,
We hold, therefore, that viewing the markup as a sales tax, the legal incidence of that tax was intended to rest upon instrumentalities of the United States. 9 We turn therefore to consideration of the question *611 whether the Buck Act is of assistance to the Tax Commission in its attempt to enforce Regulation 25.
IV
The Buck Act was enacted in 1940 10 to bar the United States, among other things, from asserting immunity from state sales and use taxes on the ground that “the Federal Government has exclusive jurisdiction over the area where the transaction occurred.” S. Rep. No. 1625, 76th Cong., 3d Sess., 2 (1940). Section 105 (a) of the Buck Act provides:
“No person shall be relieved from liability for payment of, collection of, or accounting for any sales or use tax levied by any State, or by any duly constituted taxing authority therein, having jurisdiction to levy such a tax, on the ground that the sale or use, with respect to which such tax is levied, occurred in whole or in part within a Federal area; and such State or taxing authority shall have full jurisdiction and power to levy and collect any such tax in any Federal area within such State to the same extent and with the same effect as though súeh area was not a Federal area.”
The District Court concluded that under this section “Congress has legislatively acceded to Mississippi’s markup on . . . wholesale liquor transactions.”
Section 107 (a) of the Buck Act, however, contains a limitation upon the application of § 105 (a). It provides that § 105 (a) “shall not be deemed to authorize the levy or collection of any tax on or from the United
*612
States or any instrumentality thereof . . .
11
Although the District Court recognized that § 107 (a) “limits” § 105 (a), the court held that § 107 (a) was inapplicable in light of its holding that the legal incidence of the tax was on the distillers. Our reversal of the District Court in that respect and our holding that the legal incidence of the tax is upon the United States plainly brings § 107 (a) into play. The section can only be read as an explicit congressional preservation of federal immunity from state sales taxes unconstitutional under the immunity doctrine announced by Mr. Chief Justice Marshall in
McCulloch
v.
Maryland,
Nor does the Twenty-first Amendment require a different result. When the case was last here we held that “the Twenty-first Amendment confers no power on a State to regulate — whether by licensing, taxation, or otherwise — the importation of distilled spirits into territory over which the United States exercises exclusive jurisdiction [pursuant to Art. I, § 8, cl. 17, of the Constitution].”
“To sustain the tax which Kentucky has imposed in this case would require nothing short of squarely holding that the Twenty-first Amendment has completely repealed the Export-Import Clause so far as intoxicants are concerned. Nothing in the language of the Amendment nor in its history leads to such an extraordinary conclusion. This Court has never intimated such a view, and now that the claim for the first time is squarely presented, we expressly reject it.”377 U. S., at 345-346 .
Hostetter
held that the Twenty-first Amendment did not supersede the Commerce Clause, Art. I, § 8, cl. 3, so as to permit the State of New York to prohibit the sale of liquor, under the supervision of United States Customs, to departing international airline passengers. We said that “[s]uch a conclusion would be patently bizarre and is demonstrably incorrect.”
Reversed.
Notes
Regulation 25 provides:
“Post exchanges, ship stores, and officers’ clubs located on military reservations and operated by military personnel (including those operated by the National Guard) shall have the option of ordering alcoholic beverages direct from the distiller or from the Alcoholic Beverage Control Division of the State Tax Commission. In the event an order is placed by such organization directly with a dis *601 tiller, a copy of such order shall be immediately mailed to the Alcoholic Beverage Control Division of the State Tax Commission.
“All orders of such organizations shall bear the usual wholesale markup in price but shall be exempt from all state taxes. The price of such alcoholic beverages shall be paid by such organizations directly to the distiller, which shall in turn remit the wholesale markup to the Alcoholic Beverage Control Division of the State Tax Commission monthly covering shipments made for the previous month.”
The United States acquired exclusive jurisdiction over the lands composing Keesler Air Force Base under the terms of § 1, 84 Stat. 835, 40 U. S. C. § 255, in a series of letters between the Governor of Mississippi and the Secretary of War. On January 9, 1945, Secretary of War Stimson wrote Governor Bailey acknowledging the acquisition of exclusive jurisdiction as required by §255: “Accordingly, notice is hereby given that the United States accepts exclusive jurisdiction over all lands acquired by it for military purposes within the State of Mississippi, title to which has heretofore vested in the United States, and over which exclusive jurisdiction has not heretofore obtained.” In 1942 and 1943, the Secretary of the Navy filed Declarations of Taking in three separate actions in the United States District Court for the Southern District of Mississippi to acquire the lands for the Naval Construction Battalion Center. In accordance with the requirement of §255, the Department of the Navy formally accepted exclusive jurisdiction over these lands in two letters to the Governor dated December 14, 1942, and January 6, 1944.
The parties stipulated that the amount of markups paid by nonappropriated fund activities on the four military installations from September 1966 through July 31, 1971, totaled $648,421.92. Counsel for the United States estimated that by now this amount has doubled. Tr. of Oral Arg. 6.
Article I, §8, cl. 17, provides:
“. . . Congress shall have Power . . . [t]o exercise exclusive Legislation ... over all Places purchased by the Consent of the Legislature of the State in which the Same shall be, for the Erection of Forts, Magazines, Arsenals, dock-yards, and other needful Buildings.”
The District Court was also directed on remand to determine the merits of the Government’s argument that Regulation 25 was invalid under the Supremacy Clause because it constituted an attempt by the State to interfere with federal procurement regulations and policy, see 32 CFR §261.4 (c) (1974), established by the Secretary of Defense pursuant to authority granted him by Congress. The District Court rejected the argument as without merit.

Act of Oct. 9, 1940, c. 787, 54 Stat. 1059, codified as 4 U. S. C. § 105 et seq. by Act of July 30, 1947, § 105 et seq., 61 Stat. 644.
The legislative history associated with the amendment of § 107 in 1954 describes the purpose of the section as follows: “Section 107 sets up certain exceptions to the power of States to tax in [federal] areas . . . .” See H. R. Rep. No. 1981, 83d Cong., 2d Sess., 2 (1954). See also S. Rep. No. 2498, 83d Cong., 2d Sess., 3 (1954).
Section 107 (a) provides: “The provisions of [§ 105 of this Act] shall not be deemed to authorize the levy or collection of any tax on or from the United States or any instrumentality thereof, or the levy or collection of any tax with respect to sale, purchase, storage, or use of tangible personal property sold by the United States or any instrumentality thereof to any authorized purchaser,” 4 U. S. C. § 107 (a). An “authorized purchaser” is defined in § 107 (b) as one who buys goods from military commissaries, ship’s stores, or similar voluntary unincorporated organizations. 4 U. S. C. § 107 (b), as amended, Act of Sept. 3, 1954, §4, 68 Sta't. 1227. There is no question that the portion of § 107 (a) dealing with a tax on or from the United States or any instrumentality thereof was intended to be distinct from the remaining portion of the section dealing with taxes on goods sold to an “authorized purchaser.” See S. Rep. No. 1625, 76th Cong., 3d Sess., 3-4 (1940).

Andrews, supra,
does not support the Tax Commission’s argument under the Buck Act. In
Polar,
the Court rejected an attack by milk producers upon a Florida gallonage tax imposed upon milk distributed by them, including milk sold to military bases located within the State. As to the sales to the military bases, over which the United States exercised exclusive jurisdiction, the Court indicated that consent to the imposition of the tax was to be found in § 105 of the Buck Act. But the Court specifically distinguished situations, such as that presented here, where the tax falls “upon the facilities of the United States or upon activities conducted within these facilities . . . .”
