American Bank & Trust Co. v. Dallas County , 103 S. Ct. 3369 ( 1983 )

Justice Blackmun

delivered the opinion of the Court.

The question presented is whether a Texas property tax on bank shares, computed on the basis of the bank’s net assets without any deduction for tax-exempt United States obligations held by the bank, violates Rev. Stat. § 3701, as amended. The Texas Court of Civil Appeals ruled that it did not.

I

Until 1959, Rev. Stat. §3701, 31 U. S. C. §742, provided, in pertinent part, that “[a]ll stocks, bonds, Treasury notes, and other obligations of the United States, shall be exempt from taxation by or under State or municipal or local authority.” This Court consistently held that this language prohibited state taxes imposed on federal obligations, either directly, or indirectly as part of a tax on the taxpayer’s total property or assets. See Society for Savings v. Bowers, 349 U. S. 143, 147-148 (1955). The Court also consistently held, however, that § 3701 did not prohibit nondiscriminatory taxes imposed on discrete property interests such as corporate shares or business franchises, even though the value of that discrete interest was measured by the underlying assets, including United States obligations. See Werner Machine Co. v. Director of Taxation, 350 U. S. 492, 493-494 (1956); Society for Savings v. Bowers, 349 U. S., at 147-148; Des Moines National Bank v. Fairweather, 263 U. S. 103, 112 (1923); Home Savings Bank v. Des Moines, 205 U. S. 503, 518-519 (1907); Provident Institution v. Massachusetts, 6 Wall. 611, 629-632 (1868). Similarly, the Court interpreted Rev. Stat. § 3701 not to prohibit taxes imposed on a discrete transaction, such as an inheritance, even though the value of the inheritance was measured according to the value of the federal obligations transferred. Plummer v. Coler, 178 U. S. 115, 133-134 (1900). In 1956, the Court observed that this formal but economically meaningless distinction between taxes on Government obligations and taxes on separate interests was “firmly embedded in the law.” Society for Savings v. Bowers, 349 U. S., at 148.

In 1959, Congress amended § 3701 by adding a second sentence: “This exemption extends to every form of taxation that would require that either the obligations or the interest thereon, or both, be considered, directly or indirectly, in the computation of the tax,” with exceptions only for nondiscriminatory franchise taxes or other nonproperty taxes, and for estate or inheritance taxes. Act of Sept. 22, 1959, § 105(a), 73 Stat. 622.¹ The issue is whether this amendment extends to a state bank shares tax.

In 1979 and 1980, Texas imposed a property tax on bank shares and a separate tax on the real estate holdings of banks. Tex. Rev. Civ. Stat. Ann., Art. 7166 (Vernon I960).² It required each bank doing business in the State to report its real estate to the local tax assessor, and to submit a list of its shareholders with the number of shares owned by each. The shareholders were required to report the actual value of their shares to the assessor in the bank’s jurisdiction. To prevent double taxation, each share was to be taxed to the shareholder on the difference between the share’s cash value and the proportionate amount per share of the bank’s real estate assessment.

Petitioners are certain state and national banks and their shareholders. Respondents are taxing subdivisions of the State of Texas, and officers and Boards of Equalization of those subdivisions, that levied taxes on petitioners’ bank shares pursuant to Art. 7166. In determining the value of the bank shares subject to the tax, respondents included the value of United States obligations held by the banks. Petitioners sought mandamus, declaratory, and injunctive relief against respondents in state court, asserting that § 3701 required that the value of their bank shares be reduced by the proportionate value of the United States obligations held by the bank.

In its initial opinion concerning petitioner Bank of Texas, the Texas Court of Civil Appeals held that the plain language of §3701, as amended, precludes consideration of United States obligations in the computation of any state or local tax. App. to Pet. for Cert. 50a. On motions for rehearing, the court withdrew its original opinion and, instead, upheld the tax. Bank of Texas v. Childs, 615 S. W. 2d 810 (1981). The court stated that, prior to the 1959 amendment to §3701, a different statute, Rev. Stat. § 5219, as amended, 12 U. S. C. §548,³ had authorized state taxation of shares of national banks without reduction in value for obligations of the United States held by the banks. 615 S. W. 2d, at 817-820. The court concluded that the 1959 amendment to § 3701 had not withdrawn this authorization. 615 S. W. 2d, at 819-820. The court reasoned that if the 1959 amendment had withdrawn the authorization granted by § 5219, in effect it would have repealed a portion of that statute, and that repeals by implication are not favored. 615 S. W. 2d, at 820-822.⁴ Similar judgments were entered in companion cases. App. to Pet. for Cert. 2a, 41a. The Court of Civil Appeals denied motions for rehearing, 615 S. W. 2d, at 823-826; App. to Pet. for Cert. 3a, 42a. The Supreme Court of Texas denied applications for writs of error. Id., at 4a, 39a, 43a.

Because the decisions of the Court of Civil Appeals appeared to be inconsistent with decisions of the Supreme Court of Montana,⁵ and because of the importance of the issue, we granted certiorari. 459 U. S. 966 (1982).

“Absent a clearly expressed legislative intention to the contrary, [the statutory] language must ordinarily be regarded as conclusive.” Consumer Product Safety Comm’n v. GTE Sylvania, Inc., 447 U. S. 102, 108 (1980). The exemption for federal obligations provided by §3701, as amended in 1959, is sweeping: with specific exceptions, it “extends to every form of taxation that would require that either the obligations or the interest thereon, or both, be considered, directly or indirectly, in the computation of the tax” (emphasis supplied). See Memphis Bank & Trust Co. v. Garner, 459 U. S. 392, 395-396 (1983) (the statute “establishes a broad exemption”).

The 1959 amendment rejected and set aside this Court’s rather formalistic pre-1959 approach to § 3701. Under that approach, if a tax were imposed on a property interest or transaction separate from the ownership of federal obligations, the method by which the tax was computed was entirely irrelevant. Plummer v. Coler, 178 U. S., at 129; Home Ins. Co. v. New York, 134 U. S. 594, 600, 602, 606 (1890). This remained true despite the Court’s recognition that the practical impact of such a tax is indistinguishable from that of a tax imposed directly on corporate assets that include federal obligations. See Society for Savings v. Bowers, 349 U. S., at 148. Under the plain language of the 1959 amendment, however, the tax is barred regardless of its form if federal obligations must be considered, either directly or indirectly, in computing the tax.

Giving the words of amended § 3701 their ordinary meaning, there can be no question that federal obligations were considered in computing the bank shares tax at issue here. In context, the word “considered” means taken into account, or included in the accounting.⁶ The tax at issue was computed by use of an “equity capital formula,” which involved determining the amount of the bank’s capital assets, subtracting from that figure the bank’s liabilities and the assessed value of the bank’s real estate, and then dividing the result by the number of shares. 615 S. W. 2d, at 816. Plainly, such a tax takes into account, at least indirectly, the federal obligations that constitute a part of the bank’s assets. Cf. Society for Savings v. Bowers, 349 U. S., at 146-147 (tax on total assets of corporation is tax on federal obligations it owns); New Jersey Realty Title Ins. Co. v. Division of Tax Appeals, 338 U. S. 665, 672-673 (1950) (same); Bank Tax Case, 2 Wall. 200, 208-209 (1865) (same).⁷

The express exceptions to the 1959 amendment — franchise taxes and estate and inheritance taxes — reinforce this conclusion. Just as state tax laws relating to corporate or bank shares generally assess the shares according to the value of the corporation’s assets, see Society for Savings v. Bowers, 349 U. S., at 148, franchise and estate and inheritance taxes customarily assess the franchise or the demise at the value of the assets of the business or at the value of the property inherited. See, e. g., Werner Machine Co. v. Director of Taxation, 350 U. S., at 492 (franchise tax measured by “net worth”); Plummer v. Coler, 178 U. S., at 134 (inheritance tax measured by “the value of the property passing”); Home Ins. Co. v. New York, 134 U. S., at 599 (franchise tax measured by “capital stock and dividends”).

Prior to the 1959 amendment, franchise and estate and inheritance taxes measured by the value of federal obligations, like bank shares taxes, were upheld on the theory that the tax was levied on the franchise or the transfer of property, rather than on the ownership interest in the federal securities themselves. By expressly exempting franchise and estate and inheritance taxes from the amended § 3701, Congress manifested its awareness that the new language would broaden significantly the prohibition as it had been construed by the courts. Congress must have believed that franchise and estate and inheritance taxes required federal obligations to “be considered, directly or indirectly, in the computation of the tax”; otherwise, the specific exemptions for these taxes would have been superfluous. There is no reason to conclude that shares taxes are any different.

The language of § 3701 encompasses “every form of taxation,” and is inconsistent with implied exceptions. Cf. Lewis v. United States, 445 U. S. 55, 60-62 (1980). From the specific exceptions for franchise and estate and inheritance taxes, and the conspicuous omission of shares taxes from that group, only one inference is possible: Congress meant to bar shares taxes to the extent they consider federal obligations in the computation of the tax. Cf. Andrus v. Glover Construction Co., 446 U. S. 608, 616 (1980); Andrus v. Allard, 444 U. S. 51, 56 (1979).⁸

Respondents Dallas County et al. argue, however, that § 3701 does not prohibit the Texas tax because, on its face, the tax statute does not require use of the equity capital formula or any other formula based on the value of federal obligations. Brief for Respondents Dallas County et al. 10-11. In the present litigation, however, the assessors did use the equity capital formula, which is the usual method for assessing the value of bank shares, see Society for Savings v. Bowers, 349 U. S., at 148,⁹ and is “the usual and customary method used in Texas to arrive at such value.” City of Midland v. Midland National Bank, 607 S. W. 2d 303, 304 (1980). Respondents have not cited a single instance where a different formula was employed. Section 3701 prohibits any form of tax that would require consideration of federal obligations in computing the tax; it cannot matter whether such consideration is mandated by the tax assessor in practice or by the state statute in so many words.¹⁰ The taxes at issue therefore violated the plain language of § 3701.

B

The legislative history of the 1959 amendment to §3701, while not extensive, supports this construction of the amendment’s effect. The catalyst for the amendment was an Idaho tax “upon every individual . . . which shall be according to and measured by his net income.” See Idaho Code § 63-3011 (1948). Despite this Court’s holding that §3701 precluded direct state taxation of the interest on federal obligations, as well as taxation of the underlying obligations, see New Jersey Realty Title Ins. Co. v. Division of Tax Appeals, 338 U. S., at 675-676, Idaho’s position was that its tax need not exempt the interest received on federal obligations, because it was imposed on the individual and was merely measured by his net income, rather than being imposed on the income itself. See Hearings on Public Debt Ceiling and Interest Rate Ceiling on Bonds before the House Committee on Ways and Means, 86th Cong., 1st Sess., 69-70 (1959) (supplemental statement of Secretary of the Treasury Anderson) (Hearings). In presenting the 1959 amendment to Congress, the Secretary described Idaho’s position as “resting] upon a distinction of words which is without substance.” Id., at 71. Similar accusations had been leveled at this Court’s analogous distinctions between shares taxes and franchise taxes on the one hand, and taxes on corporate assets on the other.¹¹

Respondents suggest, however, that the 1959 amendment was intended only to make clear that income taxes like Idaho’s, on interest from federal obligations, were unlawful. Congress, according to respondents, did not mean to set aside this Court’s well-established distinction between taxes on assets and taxes on shares. We, however, have found no evidence whatsoever in the legislative history to suggest that Congress considered shares taxes to fall outside the scope of the prohibition. The fact that the 1959 legislative history refers to the Idaho tax, but not specifically to bank shares taxes, does not raise a “negative inference” limiting the amendment to this specific problem. Newport News Shipbuilding & Dry Dock Co. v. EEOC, 462 U. S. 669, 679 (1983). The amendment plainly did more than make clear that the interest on federal obligations was tax exempt. Idaho relied on the formal distinction between a tax on an individual, measured by his net income, and a tax on the income itself. See Hearings, at 70. To answer this argument, the amendment abolished the formalistic inquiry whether the tax is on a distinct interest, and replaced it with the inquiry whether “computation of the tax” requires consideration of federal obligations.

Nor can the 1959 amendment be read to apply only to income taxes; it reaches “every form of tax ...” (emphasis supplied). Indeed, Congress felt compelled to exempt estate and inheritance and franchise taxes from the scope of its amendment precisely because the amendment was not limited to income taxes. Congress understood the amendment’s effect; both the Senate and House Reports explained that the amendment “makes it clear that both the principal and interest on U. S. obligations are exempt from all State taxes except nondiscriminatory franchise, etc., taxes” (emphasis supplied). Senate Report, at 2; House Report, at 2. Congress intended to sweep away formal distinctions and to invalidate all taxes measured directly or indirectly by the value of federal obligations, except those specified in the amendment.

IV

In an effort to avoid this result and to resurrect the formalistic approach, respondents embark on a tour of the history of an entirely different statute, Rev. Stat. § 5219, as amended, 12 U. S. C. § 548. Section 5219, they argue, authorizes States to tax the full value of bank shares, and the 1959 amendment to § 3701 did not repeal that authorization by implication. Even if the 1959 Congress abolished the distinction between taxes on and taxes measured by the value of federal obligations, respondents conclude, the Texas tax is valid.

It is true, of course, that “repeals by implication are not favored.” Posadas v. National City Bank, 296 U. S. 497, 503 (1936). This doctrine flows from the basic principle that “courts are not at liberty to pick and choose among congressional enactments, and when two statutes are capable of co-existence, it is the duty of the courts, absent a clearly expressed congressional intention to the contrary, to regard each as effective.” Morton v. Mancari, 417 U. S. 535, 551 (1974). But, at the time the taxes at issue were assessed, § 5219 was clearly capable of coexistence with the plain language of § 3701 as amended in 1959, and there is no justification for construing § 5219 to create an inconsistency.

When the taxes challenged here were assessed, and now, § 5219 provided only that States could not impose discriminatory taxes on national banks: “For the purposes of any tax law enacted under authority of the United States or any State, a national bank shall be treated as a bank organized and existing under the laws of the State or other jurisdiction within which its principal office is located.” Section 3701’s requirement that shares taxes on all corporations not consider federal obligations in their computation easily coexists with §5219’s simple ban on discriminatory taxation of national banks. Giving each statute its common-sense meaning, the proper result in these cases could not be more clear.

Respondents, though, find an unexpressed exception for bank shares taxes in the plain language of § 3701 by reading into the plain language of §5219 an unexpressed congressional authorization to tax bank shares at their full value. Respondents argue that this silent authorization may be found in § 5219 by looking to the pre-1969 language of that section. Even assuming that such an adventure in statutory-revision would be an appropriate exercise of judicial power, respondents’ argument is based on an unnecessary construction of this earlier version of § 5219.

From 1926 until 1969, § 5219 provided that the States could tax national banks in only four ways: (1) by taxing bank shares, (2) by including bank share dividends in the taxable income of a shareholder, (3) by taxing national banks on their net income, or (4) by levying a franchise tax on national banks “according to or measured by their net income. ” Act of Mar. 25, 1926, ch. 88, 44 Stat. 223; see n. 3, supra. Respondents argue that this statute not only permitted these forms of taxation of national banks, but that in so doing it also implicitly authorized the taxation of any federal obligations held by national banks, notwithstanding independent limitations placed on taxation of federal obligations.¹²

Although respondents’ reading might be a plausible construction of the prior version of § 5219, the prior version need not be so construed. That version did not mention federal obligations; § 5219 was, and still is, addressed to the concern first considered in McCulloch v. Maryland, 4 Wheat. 316 (1819), where this Court declared that any tax on the operation of a national bank unconstitutionally burdened this instrumentality of the Federal Government. The original predecessor of §5219, §41 of the 1864 National Bank Act, 13 Stat. Ill, permitted state taxation of national banks only on their real estate and shares; such taxes, McCulloch indicated, did not violate the Constitution’s protection of national banks. 4 Wheat., at 436-437. But whether a tax imposes an intolerable burden on national banks, and whether it imposes an intolerable burden on federal obligations by threatening to diminish their value, are questions that are historically and analytically distinct. Section 3701 responds to the latter concern, first addressed in Weston v. City Council of Charleston, 2 Pet. 449 (1829). Congress might well conclude that a tax not imposing an undue burden on national banks does unduly burden federal obligations, and § 5219 and § 3701 have always been directed to, and have protected, these separate federal interests.

A state tax affecting national banks holding federal obligations implicates both federal concerns, and therefore confronts both federal barriers to state taxation. Under the statutory scheme in effect in 1959, the year § 3701 was amended, a tax not satisfying the requirements of § 5219 was invalid whether or not it also satisfied the requirements of § 3701. Compare Owensboro National Bank v. Owensboro, 173 U. S. 664, 676, 682-683 (1899) (franchise taxation of national bank violated predecessor to § 5219 prior to 1926 amendment of that statute, which permitted for the first time franchise taxes on national banks), with Provident Institution v. Massachusetts, 6 Wall., at 630-632 (franchise tax on state corporation not unlawful burden on federal obligations). Similarly, there was no reason to believe that a tax that violated § 3701 could be imposed on a bank merely because it did not also violate §5219. Indeed, while §5219 explicitly had permitted the levying of an income tax on national banks since 1923, see Act of Mar. 4, 1923, ch. 267, 42 Stat. 1499, it was never contended that this permitted the inclusion of interest from federal obligations in the national banks’ taxable income.¹³

Although it might be inferred from dicta in certain cases that the prior version of § 5219 implicitly authorized a State’s refusal to deduct the value of federal obligations from the assessed value of national bank shares, see, e. g., Cleveland Trust Co. v. Lander, 184 U. S. 111, 115 (1902); Van Allen v. Assessors, 3 Wall. 573, 584-588 (1866), this implication has not been necessary for any of the Court’s decisions in this area. In the context of bank shares taxes, until the 1959 amendment of §3701 the prohibitions of §3701 and §5219 were coextensive. Because they were permitted expressly by § 5219, such taxes did not violate the proscription of taxes on national banks. And regardless of the manner in which a shares tax was computed, it did not violate § 3701 because it was assessed on an interest separate from the federal obligations held by the bank. See, e. g., Society for Savings v. Bowers, 349 U. S., at 147. There was therefore no cause to consider whether § 5219 implicitly granted powers to burden federal obligations held by national banks that otherwise would have been denied by §3701.¹⁴

The prior version of § 5219 thus need not be read as giving implied consent to taxation of federal obligations; on its face it was addressed only to the separate interdiction on taxation of national banks, and it never was necessary to decide whether implicitly it reached further. The plain language of §3701, as amended in 1959, therefore need not be seen as an “implied repeal” of the pre-1969 version of § 5219. The 1959 amendment of § 3701 left § 5219 entirely intact. All taxes on national banks except those enumerated in § 5219 still were unlawful. A shares tax on a national bank still was lawful. The 1959 amendment simply limited the ability of States to consider federal obligations when levying any form of tax, taxes on national banks included. States still could reach the value of federal obligations by imposing the other effective form of taxation permitted by § 5219, a franchise tax, which was expressly excepted from the prohibition contained in the amended language of §3701.

The doctrine disfavoring implied repeals thus is irrelevant for these cases. It does not justify the use of an unnecessary construction of the language of an ambiguous statute that no longer is on the books to defeat the plain language of an effective statute. This is particularly true when, as here, the “impairment” of the prior statute is minimal even if the prior statute is construed so as to maximize its conflict with the later one. See Andrus v. Glover Construction Co., 446 U. S., at 618-619. Given its current language, which does not mention or even arguably authorize any form of tax, it would be singularly inappropriate for this Court to hold for the first time that § 5219 authorizes the imposition of taxes that otherwise would violate §3701.¹⁵

V

Nothing in the legislative history of the 1959 amendment to §3701 contradicts its plain language. Nor is the plain language of the amendment inconsistent with any other federal statute. In these circumstances, the plain language of § 3701 is controlling. The judgments of the Texas Court of Civil Appeals are therefore reversed.

It is so ordered.

Justice O’Connor took no part in the consideration or decision of these cases.

1 Section § 3701, as so amended, 31 U. S. C. § 742, read:

“[A]ll stocks, bonds, Treasury notes, and other obligations of the United States, shall be exempt from taxation by or under State or municipal or local authority. This exemption extends to every form of taxation that would require that either the obligations or the interest thereon, or both, be considered, directly or indirectly, in the computation of the tax, except nondiscriminatory franchise or other nonproperty taxes in lieu thereof imposed on corporations and except estate taxes or inheritance taxes.”

Title 31 of the United States Code was not enacted into positive law until 1982, when it was reformulated without substantive change. Rev. Stat. § 3701, 31 U. S. C. § 742, then was replaced by 31 U. S. C. § 3124(a) (1982 ed.). Act of Sept. 13, 1982, 96 Stat. 877, 945. Because the state taxes at issue here were levied in 1979 and 1980, the former Rev. Stat. § 3701, as amended, rather than the present 31 U. S. C. § 3124(a) (1982 ed.) technically controls these cases.

2 As of January 1, 1982, Art. 7166 was replaced by substantively similar provisions of the Texas Property Tax Code. See Tex. Tax Code Ann. §§21.09, 22.06, 23.11, 25.14 (1982). Until 1982, and at all times pertinent to these cases, Tex. Rev. Civ. Stat. Ann., Art. 7166 (Vernon 1960), read, in relevant part:

“Every banking corporation, State or national, doing business in the State shall, in the city or town in which it is located, render its real estate to the tax assessor at the time and in the manner required of individuals. At the time of making such rendition the president or some other officer of said bank shall file with said assessor a sworn statement showing the number and amount of shares of said bank, the name and residence of each shareholder, and the number and amount of shares owned by him. Every shareholder of said bank shall, in the city or town where said bank is located, render at their actual value to the tax assessor all shares owned by him in such bank; and in case of his failure to do so, the assessor shall assess such unrendered shares as other unrendered property. Each share in such bank shall be taxed only for the difference between its actual cash value and the proportionate amount per share at which its real estate is assessed. . . . Nothing herein shall be so construed as to tax national or State banks, or the shareholders thereof, at a greater rate than is assessed against other moneyed capital in the hands of individuals.”

3 Before its amendment in 1969, Rev. Stat. § 5219, as amended by the Act of Mar. 25, 1926, ch. 88, 44 Stat. 223, 12 U. S. C. § 548, provided, in relevant part:

“The legislature of each State may determine and direct, subject to the provisions of this section, the manner and place of taxing all the shares of national banking associations located within its limits. The several States may (1) tax said shares, or (2) include dividends derived therefrom in the taxable income of an owner or holder thereof, or (3) tax such associations on their net income, or (4) according to or measured by their net income. ...”

The statute required that any such tax comply with certain conditions, principally designed to prohibit discrimination against national banks.

As amended in 1969, § 5219 provides: “For the purposes of any tax law enacted under authority of the United States or any State, a national bank shall be treated as a bank organized and existing under the laws of the State or other jurisdiction within which its principal office is located.” Pub. L. 91-156, § 2(a), 83 Stat. 434.

4 The court also rejected claims that the tax violated state law and the United States Constitution by placing a tax burden on banks heavier than it placed on other “moneyed capital” in the State. 615 S. W. 2d, at 813-816, 822-823. These holdings are not before us.

5 Montana Bankers Assn. v. Montana Dept. of Revenue, 177 Mont. 112, 580 P. 2d 909 (1978); First Security Bank of Bozeman v. Montana Dept. of Revenue, 177 Mont. 119, 580 P. 2d 913 (1978). The Supreme Court of Georgia has upheld a similar bank shares tax. Bartow County Bank v. Bartow County Board of Tax Assessors, 248 Ga. 703, 285 S. E. 2d 920 (1982), appeal docketed, No. 81-1834.

6 Respondents Dallas County et al. suggest that “considered” may mean “characterized by deliberate thought,” so that a tax would be invalid under the section only if the tax assessor subjectively knew that the bank’s assets included federal obligations. Brief for Respondents Dallas County et al. 8-9. Respondents do not explain why Congress might have believed the subjective knowledge of the tax assessor worthy of federal concern. Moreover, on its face, the statute bars taxes requiring that federal obligations be considered “indirectly” in computing the tax.

7 A Texas Court of Civil Appeals itself has stated that each asset of a bank, apart from real estate holdings, is “included and considered in arriving at the value of the Bank’s shares.” City of Midland v. Midland National Bank, 607 S. W. 2d 303, 304 (1980).

8 The unenacted 31 U. S. C. §742, which codified Rev. Stat. §3701, included the introductory phrase “Except as otherwise provided by law . . . .” Rev. Stat. § 3701 itself did not include that phrase, however, and the Statutes at Large prevail over the Code whenever the two are inconsistent. Stephan v. United States, 319 U. S. 423, 426 (1943). In fact, Congress was aware that Rev. Stat. § 3701 did not contain this phrase. Both the House and Senate Reports, although mentioning the phrase at one point, see S. Rep. No. 909, 86th Cong., 1st Sess., 11 (1959) (Senate Report); H. R. Rep. No. 1148, 86th Cong., 1st Sess., 12 (1959) (House Report), properly set forth the statute without the introductory clause. Senate Report, at 22; House Report, at 25. Moreover, the Reports summarized the amendment as making clear that, with specified exceptions, “both the principal and interest on U. S. obligations are exempt from all State taxes except . . . .” Senate Report, at 2; House Report, at 2. There was no suggestion that some category of state taxes apart from those specifically preserved was to be impliedly excepted.

9 At the time the contested taxes were levied, at least six States other than Texas imposed a bank shares tax. Of the six statutes, five explicitly required that the share’s value be determined according to the value of the bank’s assets. See Ga. Code Ann. § 48-6-90 (1982); La. Rev. Stat. Ann. §47:8 (West 1970) and §47:1967(0 (West Cum. Supp. 1982); Nev. Rev. Stat. §367:025 (1981); Ohio Rev. Code Ann. §5725.04 (1980) (repealed, effective Jan. 1, 1983, see Ohio Rev. Code Ann. § 5725.04 (Supp. 1982)); Pa. Stat. Ann., Tit. 72, §7701 (Purdon Supp. 1982). One of the statutes, like Texas’, did not specify the method by which the assessment was to be made. See W. Va. Code § 11-3-14 (1974).

10 Accordingly, we need not decide whether Texas, by the use of some other method of assessing the shares, could avoid the plain prohibition of the statute.

11 See, e. g., Van Allen v. Assessors, 3 Wall. 573, 598-599 (1866) (Chase, C. J., concurring); 67 Cong. Rec. 6085-6986 (1926) (colloquy of Reps. Wingo and Cooper) (legalizing franchise tax measured by assets including federal obligations is “a use of words to conceal an idea”; “the decision of the Supreme Court which arrived at [that] conclusion gave me a headache, and it took me considerable time to be able to comprehend it”); id., at 6088 (remarks of Rep. Stevenson) (“the Supreme Court of the United States frequently obscures ideas by language as well as statesmen when they are on the stump. . . . When they held that the stock was taxable, although every dollar of it was invested in United States bonds, which were expressly exempt from taxation, they held practically the same thing”). See also Macallen Co. v. Massachusetts, 279 U. S. 620, 628-629 (1929); Society for Savings v. Bowers, 349 U. S., at 148.

12 The unenacted phrase “Except as otherwise provided by law,” added to the text of Rev. Stat. § 3701 by the codifiers of the United States Code in 1926, see n. 8, supra, almost certainly did not refer to §5219 or its predecessors. The drafters probably inserted the language as a cross-reference to the Act of Aug. 13,1894, ch. 281,28 Stat. 278, which had legislatively overruled Bank v. Supervisors, 7 Wall. 26 (1869), and modified § 3701 to the extent of removing the exemption from circulating notes and other notes circulating as currency. See W. McClenon & W. Gilbert, Index to the Federal Statutes 1874-1931, p. 1243 (1933) (listing Act of Aug. 13,1894, as an implied amendment of Rev. Stat. § 3701). In the preface to the 1926 edition of the United States Code, at v, it is said: “Acknowledgement of valuable assistance is given to W. H. McClenon. . . .”

13 Inclusion of interest from federal obligations in income for the purposes of state income taxes was prohibited by the pre-1959 version of § 3701, because the tax was imposed on, rather than being measured by, the interest. The States’ inability to include interest from federal obligations in an income tax was the primary reason the predecessor to § 5219 was amended in 1926 to permit the imposition on national banks of nondiscriminatory franchise taxes based on corporate income. See 67 Cong. Rec. 6085 (1926) (remarks of Rep. Wingo); T. Anderson, Federal and State Control of Banking 217-219 (1934).

14 Thus, we do not “disregard]” these cases, as the dissent contends. Post, at 874. We simply observe that like the former § 5219 itself these cases were ambiguous about the relationship of § 5219 to taxation of federal obligations and § 3701, and that their results in no way turned on an exception to § 3701 created by § 5219. In Van Allen v. Assessors, for example, the Court did not state unambiguously, as the dissent implies, post, at 875, that §5219 independently recognized the State’s power to tax federal obligations “irrespective of § 3701,” post, at 876, but rather stated that the statute recognized the State’s power to tax the shares of national banks. See 3 Wall, at 586. The Van Allen Court held that a bank shares tax did not illegally tax the United States obligations that constituted the capital of the bank, because the shares were “a distinct independent interest or property, held by the shareholder like any other property that may belong to him.” Id., at 584. Similarly, in Cleveland Trust Co. v. Lander, the Court recognized that it was well established that Rev. Stat. § 3701 did not bar a tax on the separate individuality of shareholders. 184 U. S., at 115. And in Des Moines National Bank v. Fairweather, 263 U. S. 103 (1923), relied upon, post, at 876, the Court addressed §3701’s application to a shares tax on national banks and held that “[a]s respects national banks, the rule is the same as with corporations in general”: “[t]he difference [between a lawful and an unlawful tax on United States obligations] turns on the distinction between the corporate assets and the shares, — the one belonging to the corporation as an artificial entity and the other to the stockholders,” 263 U. S., at 112. The Fairweather Court’s reference to Van Allen’s ruling as “settled law,” 263 U. S., at 114, in context appears to refer principally to this distinction, see id., at 113-115. Any oblique suggestions in these cases that § 5219 independently defined the States’ authority to reach the value of federal obligations held by national banks were wholly superfluous.

Finally, the “firmly embedded” exception to the general rule of immunity of federal obligations from state taxation noted in Society for Savings v. Bowers, 349 U. S., at 148, was not an immunity afforded by § 5219. Cf. post, at 876. Section 5219 was not mentioned in Bowers. The Bowers Court referred to an immunity entirely internal to § 3701, one based on “the theory that... a tax on the stockholders’ interests is not a tax on the federal obligations which are included in the corporate property.” 349 U. S., at 147. The 1959 amendment to § 3701 certainly abolished the relevance of this formalistic theory.

15 Moreover, the Court of Civil Appeals’ approach would ascribe to Congress the implausible intention to outlaw consideration of federal obligations in computing all taxes on shareholders, except taxes on shareholders of banks. As discussed above, state taxation of national banks historically has been thought to pose a threat to a federal interest independent of the threat posed by state taxation of federal obligations. Policy and logic suggest that Congress could not have meant to single out national banks for disfavored treatment.
