OKLAHOMA TAX COMM’N v. CHICKASAW NATION(1995)

No. 94-771

Argued: April 24, 1995Decided: June 14, 1995

Respondent Chickasaw Nation (Tribe) filed this action to stop Oklahoma from enforcing several state taxes against the Tribe and its members. Pertinent here, the District Court held for the State on the motor fuels tax question, and largely for the Tribe on the income tax issue. The Court of Appeals ruled for the Tribe and its members on both issues, determining: (1) that, without congressional authorization, the State could not impose a motor fuels tax on fuel sold by the Tribe at its retail stores on tribal trust land; and (2) that the State could not tax the wages of tribal members employed by the Tribe, even if they reside outside Indian country.

Held:

1. Oklahoma may not apply its motor fuels tax, as currently designed, to fuel sold by the Tribe in Indian country. Pp. 4-12.

(a) The Court declines to address the State’s argument, raised for the first time in its brief on the merits, that the Hayden-Cartwright Act expressly authorizes States to tax motor fuel sales on Indian reservations. Pp. 5-6.

(b) When a State attempts to levy a tax directly on Indian tribes or their members inside Indian country, the proper approach is not, as the State contends, to weigh the relevant state and tribal interests. Rather, a more categorical approach should be employed: Absent clear congressional authorization, a State is without power to tax reservation lands and reservation Indians. The initial and frequently dispositive question in Indian tax cases, therefore, is who bears the legal incidence of the tax, for if it is a tribe or tribal members inside Indian country, the tax cannot be enforced absent federal legislation permitting the impost. The inquiry proper in this Page II case is whether the fuels tax rests on the Tribe as retailer, or on the who sells to the Tribe or the consumer who buys from the Tribe. Judicial focus on legal incidence accords due deference to Congress’ lead role in evaluating state taxation as it bears on Indian tribes and tribal members. A “legal incidence” test, furthermore, provides a reasonably bright-line standard accommodating the reality that tax administration requires predictability. And a State unable to enforce its tax because the legal incidence falls on tribes or on Indians within Indian country, generally is free to amend its law to shift the tax’s legal incidence. Pp. 6-10.

(c) The Court of Appeals’ ruling that the fuels tax’s legal incidence rests on the retailer is reasonable. The state legislation does not expressly identify who bears the tax’s legal incidence. Nor does it contain a provision requiring that the tax be passed on to consumers. In the absence of such dispositive language, the question is one of fair interpretation of the taxing statute as written and applied. In this case, the fuels tax law’s language and structure indicate that the tax is imposed on fuel retailers. Pp. 10-12.

2. Oklahoma may tax the income of tribal members who work for the Tribe but reside in the State outside Indian country. The Court of Appeals’ holding to the contrary conflicts with the well established principle of interstate and international taxation that a jurisdiction may tax all the income of its residents, even income earned outside the taxing jurisdiction. The exception that the Tribe would carve out of the State’s taxing authority gains no support from the rule that Indians and tribes are generally immune from state taxation, as this principle does not operate outside Indian country. In addition, the Treaty of Dancing Rabbit Creek, which guarantees the Tribe and its members that “no Territory or State shall ever have a right to pass laws for the [Tribe’s] government,” provides only for the Tribe’s sovereignty within Indian country and does not confer super-sovereign authority to interfere with another jurisdiction’s sovereign right to tax income, from all sources, of those who choose to live within that jurisdiction’s limits. Nor can the Treaty be read to incorporate the repudiated doctrine that an income tax imposed on government employees should be treated as a tax on the government. The Treaty’s signatories likely gave no thought to a State’s authority to tax income of tribal members living in the State’s domain, since the Treaty’s purpose was to move the Tribe to unsettled land not then within a State. Moreover, if that doctrine were to apply, it would require exemption for nonmember as well as tribal member employees of the Tribe. Pp. 12-17.

J., and SCALIA, KENNEDY, and THOMAS, JJ., joined. BREYER, J., filed an opinion concurring in part and dissenting in part, in which STEVENS, O’CONNOR, and SOUTER, JJ., joined. [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 1]

JUSTICE GINSBURG delivered the opinion of the Court.

This case concerns the taxing authority of the State of Oklahoma over the Chickasaw Nation (Tribe) and its members. 1 We take up two questions: (1) May Oklahoma impose its motor fuels excise tax upon fuel sold by Chickasaw Nation retail stores on tribal trust land; (2) May Oklahoma impose its income tax upon members of the Chickasaw Nation who are employed by the Tribe but who reside in the State outside Indian country. 2

We hold that Oklahoma may not apply its motor fuels tax, as currently designed, to fuel sold by the Tribe in Indian country. In so holding, we adhere to settled law: [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 2] when Congress does not instruct otherwise, a State’s excise tax is unenforceable if its legal incidence falls on a Tribe or its members for sales made within Indian country. We further hold, however, that Oklahoma may tax the income (including wages from tribal employment) of all persons, Indian and non-Indian alike, residing in the State outside Indian country. The Treaty between the United States and the Tribe, which guarantees the Tribe and its members that “no Territory or State shall ever have a right to pass laws for the government of” the Chickasaw Nation, does not displace the rule, accepted interstate and internationally, that a sovereign may tax the entire income of its residents.

I

The Chickasaw Nation, a federally recognized Indian tribe, commenced this civil action in the United States District Court for the Eastern District of Oklahoma, to stop the State of Oklahoma from enforcing several state taxes against the Tribe and its members. 3 Pertinent here, the District Court, ruling on cross-motions for summary judgment, held for the State on the motor fuels tax imposition and largely for the Tribe on the income tax issue. The Court of Appeals for the Tenth Circuit ruled for the Tribe and its members on both issues: it held that the State may not apply the motor [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 3] fuels tax to fuel sold by the Tribe’s retail stores, and, further, that the State may not tax the wages of members of the Chickasaw Nation who work for the Tribe, even if they reside outside Indian country. 31 F.3d 964 (1994).

Concerning the motor fuels tax, the Tenth Circuit disapproved the District Court’s “balancing of the respective tribal and state interests” approach. Id., at 972. The legal incidence of the tax, the Court of Appeals ruled, is the key concept. That incidence, the Tenth Circuit determined, falls directly on fuel retailers – here, on the Tribe, due to its operation of two convenience stores that sell fuel to tribal members and other persons. Oklahoma’s imposition of its fuels tax on the Tribe as retailer, the Court of Appeals concluded, “conflicts with . . . the traditional scope of Indian sovereign authority.” Ibid. Because the State asserted no congressional authorization for its exaction, the Tenth Circuit declared the fuels tax preempted.

Oklahoma’s income tax, in the Court of Appeals’ view, could not be applied to any tribal member employed by the Tribe; 4 residence, the Tenth Circuit said, was “simply not relevant to [its] determination.” Id., at 979. The Court of Appeals relied on the provision of the Treaty of Dancing Rabbit Creek, Sept. 27, 1830, Art. IV, 7 Stat. 333, 334, that “no Territory or State shall ever have a right to pass laws for the government of the [Chickasaw] Nation of Red People and their descendants.” To this treaty language, the Tenth Circuit applied “the general rule that `[d]oubtful expressions are to be resolved in favor of’ the Indians.” 31 F.3d, at 978 (quoting McClanahan v. Arizona State Tax Comm’n, 411 U.S. 164, 174 (1973)). The Court of Appeals also noted [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 4] that it had endeavored to “rea[d] the treaty as the Indians [who signed it] would have understood it.” 31 F.3d, at 979.

We granted the State’s petition for certiorari, 513 U.S. ___ (1995), and now (1) affirm the Court of Appeals’ judgment as to the motor fuels tax, and (2) reverse that judgment as to the income tax applied to earnings of tribal members who work for the Tribe but reside in the State outside Indian country.

II

The Tribe contends, and the Tenth Circuit held, that Oklahoma’s fuels tax 5 is levied on retailers, not on distributors or consumers. The respect due to the Chickasaw Nation’s sovereignty, the Tribe maintains, means Oklahoma – absent congressional permission – may not collect its tax for fuel supplied to and sold by the Tribe at its convenience stores. In support of the tax immunity it asserts, the Tribe recalls our reaffirmations to this effect: “The Constitution vests the Federal Government with exclusive authority over relations with Indian tribes . . ., and in recognition of the sovereignty retained by Indian tribes even after formation of the United States, Indian tribes and individuals generally are exempt from state taxation within their own territory.” Montana v. Blackfeet Tribe, 471 U.S. 759, 764 (1985); see also, e.g., Mescalero Apache Tribe v. Jones, 411 U.S. 145, 148 (1973).

In response, Oklahoma urges that Indian tribes and their members are not inevitably but only “`generally'” immune from state taxation. Brief for Petitioner 19 [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 5] (quoting Blackfeet Tribe, 471 U.S., at 764 ). At least as to some aspects of state taxation, Oklahoma asserts, an approach “balancing the state and tribal interests” is in order. Brief for Petitioner 17. Even if the legal incidence of the fuels tax falls on the Tribe (as retailer), Oklahoma concludes, tax immunity should be disallowed here because “the state interest supporting the levy is compelling, . . . the tribal interest is insubstantial, and . . . the state tax would have no effect on `tribal governance and self-determination.'” Id., at 22 (emphasis in original).

In the alternative, Oklahoma argues that the Court of Appeals “erred in holding that the legal incidence of the fuel tax falls on the retailer.” Id., at 10. Moreover, the State newly contends, even if the fuels tax otherwise would be impermissible, Congress, in the 1936 Hayden-Cartwright Act, 4 U.S.C. 104, expressly permitted state taxation of reservation activity of this type. Brief for Petitioner 23-24.

We set out first our reason for refusing to entertain at this late date Oklahoma’s argument that the Hayden-Cartwright Act expressly permits state levies on motor fuels sold on Indian reservations. We then explain why we agree with the Tenth Circuit on the Tribe’s exemption from Oklahoma’s fuels tax.

A

On brief, the State points out – for the first time in this litigation – that the Hayden-Cartwright Act, 4 U.S.C. 104, expressly authorizes States to tax motor fuel sales on “United States military or other reservations.” 104(a). The Act’s word “reservations,” Oklahoma maintains, encompasses Indian reservations. Brief for Petitioner 23-24. We decline to address this question of statutory interpretation. The State made no reference to the Hayden-Cartwright Act in the courts of first and second instance. And even though the Court [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 6] of Appeals flagged the Act’s possible relevance, 6 Oklahoma did not mention this 1936 legislation in its petition for certiorari. Nor is Oklahoma’s newly discovered claim of vintage legislative authorization “fairly included” 7 in the question the State tendered for our review: “Whether principles of federal pre-emption or Indian sovereignty preclude a State from imposing a tax on motor fuel sold by an Indian tribe . . . . ?” Pet. for Cert. (i). As a court of review, not one of first view, we will entertain issues withheld until merits briefing “`only in the most exceptional cases.'” Yee v. Escondido, 503 U.S. 519, 535 (1992) (citation omitted). This case does not fit that bill.

B

Assuming, then, that Congress has not expressly authorized the imposition of Oklahoma’s fuels tax on fuel sold by the Tribe, we must decide if the State’s exaction is nonetheless permitted. Oklahoma asks us to make the determination by weighing the relevant state and tribal interests, and urges that the balance tilts in its favor. Oklahoma emphasizes that the fuel sold is used “almost exclusively on state roads,” imposing “very [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 7] substantial costs on the State – but no burden at all on the Tribe.” Brief for Petitioner 9. The State also stresses that “the levy does not reach any value generated by the Tribe on Indian land,” id., at 10; i.e., the fuel is not produced or refined in Indian country, and is often sold to outsiders.

We have balanced federal, state, and tribal interests in diverse contexts, notably, in assessing state regulation that does not involve taxation, see, e.g., California v. Cabazon Band of Mission Indians, 480 U.S. 202, 216 -217 (1987) (balancing interests affected by State’s attempt to regulate on-reservation high-stakes bingo operation), and state attempts to compel Indians to collect and remit taxes actually imposed on non-Indians. See, e.g., Moe v. Confederated Salish and Kootenai Tribes of Flathead Reservation, 425 U.S. 463, 483 (1976) (balancing interests affected by State’s attempt to require tribal sellers to collect cigarette tax on non-Indians; precedent about state taxation of Indians is not controlling because “this [collection] burden is not, strictly speaking, a tax at all”).

But when a State attempts to levy a tax directly on an Indian tribe or its members inside Indian country, rather than on non-Indians, we have employed, instead of a balancing inquiry, “a more categorical approach: `[A]bsent cession of jurisdiction or other federal statutes permitting it,’ we have held, a State is without power to tax reservation lands and reservation Indians.” County of Yakima v. Confederated Tribes and Bands of Yakima Nation, 502 U.S. 251, 258 (1992) (citation omitted). Taking this categorical approach, we have held unenforceable a number of state taxes whose legal incidence rested on a tribe or on tribal members inside Indian country. See, e.g., Bryan v. Itasca County, 426 U.S. 373 (1976) (tax on Indian-owned personal property situated in Indian country); McClanahan v. Arizona State Tax Comm’n, 411 U.S. 164, 165 -166 (1973) (tax [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 8] on income earned on reservation by tribal members residing on reservation).

The initial and frequently dispositive question in Indian tax cases, therefore, is who bears the legal incidence of a tax. If the legal incidence of an excise tax rests on a tribe or on tribal members for sales made inside Indian country, the tax cannot be enforced absent clear congressional authorization. See, e.g., Moe, 425 U.S., at 475 -481 (Montana’s cigarette sales tax imposed on retail consumers could not be applied to on-reservation “smoke shop” sales to tribal members). But if the legal incidence of the tax rests on non-Indians, no categorical bar prevents enforcement of the tax; if the balance of federal, state, and tribal interests favors the State, and federal law is not to the contrary, the State may impose its levy, see Washington v. Confederated Tribes of Colville Reservation, 447 U.S. 134, 154 -157 (1980), and may place on a tribe or tribal members “minimal burdens” in collecting the toll. Department of Taxation and Finance of New York v. Milhelm Attea & Bros., 512 U.S., ___, ___ (1994) (slip op., at 12). Thus, the inquiry proper here is whether the legal incidence of Oklahoma’s fuels tax rests on the Tribe (as retailer), or on some other transactors – here, the wholesalers who sell to the Tribe or the consumers who buy from the Tribe. 8

Judicial focus on legal incidence in lieu of a more venturesome approach accords due deference to the lead [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 9] role of Congress in evaluating state taxation as it bears on Indian tribes and tribal members. See Yakima, 502 U.S., at 267 . The State complains, however, that the legal incidence of a tax “`has no relationship to economic realities.'” Brief for Petitioner 30 (quoting Complete Auto Transit, Inc. v. Brady, 430 U.S. 274, 279 (1977)). But our focus on a tax’s legal incidence accommodates the reality that tax administration requires predictability. The factors that would enter into an inquiry of the kind the State urges are daunting. If we were to make “economic reality” our guide, we might be obliged to consider, for example, how completely retailers can pass along tax increases without sacrificing sales volume – a complicated matter dependent on the characteristics of the market for the relevant product. Cf. Yakima, 502 U.S., at 267 -268 (categorical approach safeguards against risk of litigation that could “engulf the States’ annual assessment and taxation process, with the validity of each levy dependent upon a multiplicity of factors that vary from year to year, and from parcel to parcel”).

By contrast, a “legal incidence” test, as 11 States with large Indian populations have informed us, “provide[s] a reasonably bright-line standard which, from a tax administration perspective, responds to the need for substantial certainty as to the permissible scope of state taxation authority.” Brief for South Dakota et al. as Amici Curiae 2. 9 And if a State is unable to enforce a tax because the legal incidence of the impost is on Indians or Indian tribes, the State generally is free to amend its law to shift the tax’s legal incidence. So, in [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 10] this case, the State recognizes and the Tribe agrees that Oklahoma could accomplish what it here seeks “by declaring the tax to fall on the consumer and directing the Tribe to collect and remit the levy.” Pet. for Cert. 17; see Brief for Respondent 10-13. 10

C

The State also argues that, even if legal incidence is key, the Tenth Circuit erred in holding that the fuels tax’s legal incidence rests on the retailer (here, the Tribe). We consider the Court of Appeal’s ruling on this point altogether reasonable, and therefore uphold it. See, e.g., Haring v. Prosise, 462 U.S. 306, 314 , n. 8 (1983) (noting “our practice to accept a reasonable construction of state law by the court of appeals”).

The Oklahoma legislation does not expressly identify who bears the tax’s legal incidence – distributors, retailers, or consumers; nor does it contain a “pass through” provision, requiring distributors and retailers to pass on the tax’s cost to consumers. Cf. Moe, 424 U.S., at 482 (statute at issue provided that Montana cigarette tax “shall be conclusively presumed to be [a] direct [tax] on the retail consumer precollected for the purpose of convenience and facility only”).

In the absence of such dispositive language, the question is one of “fair interpretation of the taxing statute as written and applied.” California Bd. of Equalization v. Chemehuevi Tribe, 474 U.S. 9, 11 (1985) (per curiam). Oklahoma’s law requires fuel distributors to “remit” the amount of tax due to the Tax Commission; [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 11] crucially, the statute describes this remittal by the distributor as “on behalf of a licensed retailer.” Okla. Stat., Tit. 68, 505(C) (1991) (emphasis added). The inference that the tax obligation is legally the retailer’s, not the distributor’s, is supported by the prescriptions that sales between distributors are exempt from taxation, 507, but sales from a distributor to a retailer are subject to taxation. 505(E). Further, if the distributor remits taxes it subsequently is unable to collect from the retailer, the distributor may deduct the uncollected amount from its future payments to the Tax Commission. 505(C). The distributor, then, “is no more than a transmittal agent for the taxes imposed on the retailer.” 31 F.3d, at 971. And for their services as “agent of the state for [tax] collection,” distributors retain a small portion of the taxes they collect. 506(a).

The fuels tax law contains no comparable indication that retailers are simply collection agents for taxes ultimately imposed on consumers. No provision sets off the retailer’s liability when consumers fail to make payments due; neither are retailers compensated for their tax collection efforts. And the tax imposed when a distributor sells fuel to a retailer applies whether or not the fuel is ever purchased by a consumer. See, e.g., 502 (“There is hereby levied an excise tax . . . upon the sale of each and every gallon of gasoline sold, or stored and distributed, or withdrawn from storage . . . .”). Finally, Oklahoma’s law imposes no liability of any kind on a consumer for purchasing, possessing, or using untaxed fuel; in contrast, the legislation makes it unlawful for distributors or retailers “to sell or offer for sale in this state, motor fuel or diesel fuel while delinquent in the payment of any excise tax due the state.” 505(C).

As the Court of Appeals fairly and reasonably concluded: “[T]he import of the language and the structure of the fuel tax statutes is that the distributor collects [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 12] the tax from the retail purchaser of the fuel”; the “motor fuel taxes are legally imposed on the retailer rather than on the distributor or the consumer.” 31 F.3d, at 971-972.

III

Regarding Oklahoma’s income tax, the Court of Appeals declared that the State may not tax the wages of members of the Chickasaw Nation who work for the Tribe, including members who reside in Oklahoma outside Indian country.

The holding on tribal members who live in the State outside Indian country runs up against a well established principle of interstate and international taxation – namely, that a jurisdiction, such as Oklahoma, may tax all the income of its residents, even income earned outside the taxing jurisdiction: 11

[ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 13]

This “general principl[e] . . . ha[s] international acceptance.” American Law Institute, Federal Income Tax Project: International Aspects of United States Income Taxation 4, 6 (1987); see, e.g., C. Cretton, Expatriate Tax Manual 1 (2d ed. 1991) (“An individual who is resident in the UK is subject to income tax on all his sources of income, worldwide.”). It has been applied both to the States, e.g., Shaffer v. Carter, 252 U.S. 37, 57 (1920); see 2 J. Hellerstein & W. Hellerstein, State Taxation 20.04, p. 20-13 (1992), and to the Federal Government. E.g., Cook v. Tait, 265 U.S. 47, 56 (1924); see 1 J. Isenbergh, International Taxation 45-56 (1990). 12

The Tribe seeks to block the State from exercising its ordinary prerogative to tax the income of every resident; in particular, the Tribe seeks to shelter from state taxation the income of tribal members who live [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 14] in Oklahoma outside Indian country but work for the Tribe on tribal lands. 13 For the exception the Tribe would carve out of the State’s taxing authority, the Tribe gains no support from the rule that Indians and Indian tribes are generally immune from state taxation, McClanahan v. Arizona State Tax Comm’n, 411 U.S. 164 (1973), as this principle does not operate outside Indian country. Oklahoma Tax Comm’n v. Sac and Fox Nation, 508 U.S. ___, ___ (1993) (slip op., at 8-10).

Notably, the Tribe has not asserted here, or before the Court of Appeals, that the State’s tax infringes on tribal self-governance. See Brief in Opposition 9-10 (“infringement” question is not presented to this Court); Brief for Respondent 42, n. 37; see also Sac and Fox, 508 U.S., at ___ (slip op., at 11) (reserving question “whether the Tribe’s right to self-governance could operate independently of its territorial jurisdiction to pre-empt the State’s ability to tax income earned from work performed for the Tribe itself when the employee does not reside in Indian country”). 14

Instead, the Tribe relies on the argument that Oklahoma’s levy impairs rights granted or reserved by federal law. See Mescalero Apache Tribe v. Jones, 411 U.S. 145, 148 -149 (1973) (“[E]xpress federal law to the contrary” overrides the general rule that “Indians going beyond reservation boundaries have generally been held subject to nondiscriminatory state law otherwise applicable to all citizens of the State.”). The Tribe invokes the [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 15] Treaty of Dancing Rabbit Creek, Sept. 27, 1830, Art. IV, 7 Stat. 333-334, which provides in pertinent part:

Nation of Red People the jurisdiction and government of all the persons and property that may be within their limits west, so that no Territory or State shall ever have a right to pass laws for the government of the [Chickasaw] Nation of Red People and their descendants . . . but the U.S. shall forever secure said [Chickasaw] Nation from, and against, all [such] laws . . . .”

According to the Tribe, the State’s income tax, when imposed on tribal members employed by the Tribe, is a law “for the government of the [Chickasaw] Nation of Red People and their descendants,” and it is immaterial that these “descendants” live outside Indian country.

In evaluating this argument, we are mindful that “treaties should be construed liberally in favor of the Indians.” County of Oneida v. Oneida Indian Nation, 470 U.S. 226, 247 (1985). But liberal construction cannot save the Tribe’s claim, which founders on a clear geographic limit in the Treaty. By its terms, the Treaty applies only to persons and property “within [the Nation’s] limits.” We comprehend this Treaty language to provide for the Tribe’s sovereignty within Indian country. We do not read the Treaty as conferring super-sovereign authority to interfere with another jurisdiction’s sovereign right to tax income, from all sources, of those who choose to live within that jurisdiction’s limits. [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 16]

The Tribe and the United States 16 further urge us to read the Treaty in accord with the repudiated view that an income tax imposed on government employees should be treated as a tax on the government. See Dobbins v. Commissioners of Erie County, 16 Pet. 435 (1842). But see Graves v. New York ex rel. O’Keefe, 306 U.S. 466, 480 (1939) (“The theory, which once won a qualified approval, that a tax on income is legally or economically a tax on its source, is no longer tenable . . . .”). Under this view, a tax on tribal members employed by the Tribe would be seen as an impermissible tax on the Tribe itself.

We doubt the signatories meant to incorporate this now-defunct view into the Treaty. They likely gave no thought to a State’s authority to tax the income of tribal members living in the State’s domain, because they did not expect any members to be there. On the contrary, the purpose of the Treaty was to put distance between the Tribe and the States. Under the Treaty, the Tribe moved across the Mississippi River, from its traditional lands within Mississippi and Alabama to unsettled lands not then within a State. See D. Hale & A. Gibson, The Chickasaw 46-59 (1991).

Moreover, importing the Dobbins rule into the Treaty [ OKLAHOMA TAX COMM’N v. CHICKASAW NATION, ___ U.S. ___ (1995) , 17] would prove too much. That dubious doctrine, by typing taxation of wages earned by tribal employees as taxation of the Tribe itself, would require an exemption for all employees of the Tribe – not just tribal members, but nonmembers as well. The Court of Appeals rejected such an extension, see 31 F.3d, at 975 (“It is settled that the income tax is imposed on the employee, not the employer . . . . Therefore, to the extent that the income tax is imposed on non-member employees who have no established claim to tribal ancestry, the tax does not infringe upon the treaty prohibition.”), and even the Tribe is not urging this view before us, admitting that it is “substantially more tenuous.” Brief for Respondent 47.

* * *

For the reasons stated, we affirm the judgment of the Court of Appeals as to the motor fuels tax, reverse that judgment as to the income tax, and remand the case for proceedings consistent with this opinion.

APPENDIX

Treaty of Dancing Rabbit Creek, Sept. 27, 1830, Article IV 7 Stat. 333-334

The Government and people of the United States are hereby obliged to secure to the said [Chickasaw] Nation of Red People the jurisdiction and government of all the persons and property that may be within their limits west, so that no Territory or State shall ever have a right to pass laws for the government of the [Chickasaw] Nation of Red People and their descendants; and that no part of the land granted them shall ever be embraced in any Territory or State; but the U.S. shall forever secure said [Chickasaw] Nation from, and against, all laws except such as from time to time may be enacted in their own National Councils, not inconsistent with the Constitution, Treaties, and Laws of the United States; and except such as may, and which have been enacted by Congress, to the extent that Congress under the Constitution are required to exercise a legislation over Indian Affairs. But the [Chickasaws], should this Treaty be ratified, express a wish that Congress may grant to the [Chickasaws] the right of punishing by their own laws, any white man who shall come into their nation, and infringe any of their national regulations.
