We must decide whether a non-Indian contractor who purchases construction materials from non-Indian vendors, which are later delivered to a construction site on Indian land, is exempt from state sales taxes. The California State Board of Equalization (the “Board”) appeals the grant of summary judgment in favor of the Barona Band of Mission Indians (the “Tribe”) in which the district court determined that the balancing test set forth in
White Mountain Apache Tribe v. Bracker,
I. BACKGROUND
After nearly two centuries of displacement of the Barona Band of Mission Indians by European and then American encroachment, the United States enacted legislation to provide a tract of land in rural San Diego County to serve as a reservation for the Tribe. Until the early 1990s, however, the Tribe suffered from deep structural economic difficulties. Following the nationwide trend of Native Americans seeking to infuse economic life into depressed reservations, the Tribe opened up a casino in 1996: the Barona Valley Ranch Resort & Casino—“Where The Real Players Play, and Win.”
By 2001, enough of these real players had played and lost for the Tribe to plan a $75 million expansion to the casino floor and hotel, replete with a new wedding chapel, parking structure and other resort amenities. The Tribe entered into a lump sum contract with a general contractor, Hensel Phelps Construction Co. (the “prime contract”) to construct the expansion. Under California law, a lump sum contract “means a contract under which the contractor for a stated lump sum agrees to furnish and install materials or fixtures, or both.” Cal. Admin. Code tit. 18, § 1521(a)(8). Under the prime contract’s terms, Hensel Phelps entered into a series of subcontracts with contractors in the various trades to complete discrete tasks. To that end, Hensel Phelps subcontracted with Helix Electric, Inc. to perform the expansion’s electrical work.
As part of the prime contract terms, the Tribe touted a method it had devised to circumvent state sales tax, which would otherwise fall on the contractor, by scheduling deliveries to occur on tribal lands. Section 3.6.2 of the prime contract reads: “[Barona Band] is a federally recognized Indian Tribe and is therefore qualified for an exemption from California state sales and use tax on the purchase of tangible personal property if certain criteria are met. This Project is being structured, in accordance with Attachment O, to take advantage of the tax-exempt status of the [Tribe].” Attachment “0” to the prime contract carefully details the steps necessary for Hensel Phelps and its subcontractors to enjoy sales tax-free construction work. Under Attachment “0,” Hensel Phelps and any subcontractor are designated as the Tribe’s “purchasing agent for the procurement of Construction Supplies.” The contractual language next provides a blueprint for the parties to follow in order to avoid state sales taxes. In bold lettering, Attachment “0” requires that any purchase made by Hensel Phelps and its subcontractors should only become officially consummated, with title transferring, on the Tribe’s property. 2 All “shipping orders and delivery receipts,” according to *1188 the contract, must include the following language:
THIS SALE IS NOT COMPLETE, AND TITLE DOES NOT PASS, UNTIL DELIVERY IS ACCEPTED BY THE BUYER ON THE HARONA INDIAN RESERVATION.
In a further effort to shield subcontractors from California state sales tax, the prime contract directs that the “Contractor shall not make advance payments to suppliers for materials or equipment which have not been delivered or stored at this site.” Provided that Hensel Phelps and its subcontractors properly follow these steps, the Tribe promises to indemnify and defend them against any assessment of tax liability.
Under these terms, Helix Electric performed nearly four million dollars worth of sales-tax-free electrical work on the casino expansion. A Board-conducted audit concluded that Helix Electric owed slightly over $200,000 in sales and use tax emanating from purchases of construction materials—with title purporting to transfer on Tribe territory—from non-Indian vendors for use on the casino expansion. The Board issued a formal Notice of Determination to Helix demanding that it pay sales taxes in that amount. Helix Electric then sought indemnification from Hensel Phelps, which in turn sought reimbursement from the Tribe. The Tribe sued individual members of the Board in them official capacity in the United States District Court for the Southern District of California, seeking declaratory relief. The Tribe sought a judicial determination that the California state sales tax was invalid (1) per se as a direct tax on the Tribe; (2) under the Bracket balancing test as a tax leveled against non-Indians on Indian territory; or (3) as preempted by the Indian Gaming Regulatory Act, 25 U.S.C. §§ 2701, et seq. (“IGRA”). The parties filed cross-motions for summary judgment and submitted a Joint Statement of Undisputed Material Facts.
While the district court disagreed that the tax was a per se improper tax levied against the Tribe, it did agree that the tax failed the Bracket balancing test and granted the Tribe’s motion for summary judgment. The Board timely appeals.
II. DISCUSSION
A. Per Se Invalidity
Historically, the United States Supreme Court treated reservations as places where, in Chief Justice Marshall’s words, the “laws of [a State] can have no force.”
Worcester v. Georgia,
The historically entrenched idea of tribal autonomy, however, remains central to our reasoning when confronted with the application of state laws on tribal territory. “[Tjraditional notions of Indian self-government are so deeply engrained in our jurisprudence that they have provided an important ‘backdrop’ against which vague
*1189
or ambiguous federal enactments must always be measured.”
Braeker,
This legal framework has often required us to undertake careful balancing of various interests.
See Bracker,
The dispositive question for
per se
analysis is who the state is taxing and where. “[Ujnder our Indian tax immunity cases, the ‘who’ and the ‘where’ of the challenged tax have significant consequences. We have determined that ‘[t]he initial and frequently dispositive question in Indian tax cases ... is
who
bears the legal incidence of [the] tax.’ ”
Wagnon v. Prairie Band Potawatomi Nation,
The party bearing the legal incidence of a state tax may well differ from the party bearing the economic burden of that tax. For instance, under Attachment “O” to the prime contract, the Tribe will be the economically burdened party due to its promise to indemnify Hensel Phelps and Helix Electric for any state sales tax they are required to pay if the Board prevails. That the Tribe will pay the tax, however, does not resolve the question of who bears the tax’s legal incidence. The Court has rejected an argument equating the two: “[0]ur focus on a tax’s legal incidence accommodates the reality that tax administration requires predictability.... 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.”
Oklahoma,
*1190
Tax Comm’n,
Therefore, we must examine the underlying California statutes: to determine whether the legal incidence falls upon the Tribe, which would render the tax per se invalid, or Helix Electric, a non-Indian party beyond the categorical exemption from state taxation. As the district court correctly noted, “[u]nder California statutes and regulations, a construction contractor [Helix Electric] is the ‘consumer’ of materials furnished later to a client pursuant to a construction contract.” “Either sales tax or use tax applies with respect to the sale of the materials to or the use of the materials by the construction contractor.” Cal. Admin. Code tit. 18, § 1521(b)(2)(A)(l). Under Cal. Admin. Code tit. 18, § 1521(a)(8), the “lumpsum” contract entered into by the parties falls within the taxing ambit of § 1521(b)(2)(A)(l). Thus, we agree with the district court that the legal incidence of the California sales tax, under the pertinent regulations, falls upon Helix Electric, a non-Indian party.
The Tribe attempts an end-run around the “legal incidence” test by structuring its contract to designate subcontractors as “purchasing agents” for the tax-exempt Tribe. Along with the district court, we decline to extend the
per se
test, rooted in due respect for Indian autonomy, to provide tax shelters for non-Indian businesses. The parties may not alter the economic reality of a transaction—a subcontractor performing electrical work for a general contractor—to reap a windfall at the public’s expense. “The incidence of taxation depends upon the substance of a transaction.... To permit the true nature of a transaction to be disguised by mere formalisms, which exist solely to alter tax liabilities, would seriously impair the effective administration of ... tax policies.”
See Comm’r v. Court Holding Co.,
B. Bracker Balancing Test
Without the convenience of a
per se
bright line test, we turn to the
Bracker
balancing test, developed for those “difficult questions ... where, as here, a State asserts authority over the conduct of non-Indians engaging in activity on the reservation.”
Bracker,
As a backdrop to the
Bracker
test, we note a parallel line of authority that aids in our analysis. The Court has previously expressed disfavor toward tribal ma
*1191
nipulation of tax policy to gain “an artificial competitive advantage over all other businesses in a State.”
Washington v. Confederated Tribes of Colville Indian Reservation,
Tribal interests are implicated by the imposition of the California tax on the construction work performed by Helix Electric on Tribal territory. The Tribe enjoys a right to autonomy within its territory, as noted in
Bracket
itself: “[Tjhere is a significant geographical component to tribal sovereignty, a component which remains highly relevant to the preemption inquiry; though the reservation boundary is not absolute, it remains an important factor to weigh in determining whether state authority has exceeded the permissible limits.”
Bracket,
It also appears that permitting the tax on Helix Electric may affect the overall profitability of the Tribe’s casino operation. If the California sales tax is validated, the Tribe must, according to the contract, indemnify Helix Electric for over $200,000. This amount will be compounded by amounts paid to the other subcontractors, as well as Hensel Phelps. This alone, however, does not bar the imposition of a tax on non-Indians.
See Salt River Pima-Maricopa, Indian Cmty.,
The federal interests triggered by the tax are similarly minimal. Federal interests are greatest when the government’s regulation of a given sphere is “comprehensive and pervasive.”
Ramah,
The federal government has a concomitant interest in the Tribe’s economic self-sufficiency. As with the related tribal interest, the federal government’s interest in Indian economic vitality does not alone defeat an otherwise legitimate state tax.
See Salt River Pima-Maricopa Indian Cmty.,
We agree with the Board that the
Bracker
analysis tips in its favor where the state levies a neutral sales tax on non-Indians’ purchases which—but for contractual creativity—would have occurred on non-Indian land. In these circumstances, we find the state interest in the application of its general sales tax to be greater than the combined federal and tribal interests. Raising revenue to provide general gov
*1193
ernment services is a legitimate state interest.
See Crow Tribe of Indians,
C. Preemption by IGRA
The Tribe also contends that the California sales tax on the construction equipment used by Tribal subcontractors has been directly preempted by IGRA. We agree, however, with the Board that IGRA’s comprehensive regulation of Indian gaming does not occupy the field with respect to sales taxes imposed on third-party purchases of equipment used to construct the gaming facilities. 3 IGRA’s core objective is to regulate how Indian casinos function so as to “assure the gaming is conducted fairly and honestly by both the operator and players.” 25 U.S.C. § 2702(2). Extending IGRA to preempt any commercial activity remotely related to Indian gaming-employment contracts, food service contracts, innkeeper codes—• stretches the statute beyond its stated purpose. 4
The Court has developed the Bracker test to determine whether federal interests preempt state taxes. If we were to accept the Tribe’s argument that IGRA itself preempts the state taxation of non-Indian contractors working on tribal territory, we would effectively ignore Bracker and its progeny. The Court has provided an analytical framework to resolve this question, which we must apply here.
III. CONCLUSION
Because the legal incidence of the California sales tax falls upon the non-Indian subcontractor, we agree with the district court’s holding that the tax passes muster under the
Chickasaw Nation per se
test.
REVERSED AND REMANDED.
Notes
. Although the Board has not pursued on appeal its contention that we lack jurisdiction under the Tax Injunction Act, 28 U.S.C. §1341, we must consider the issue sua sponte. Having done so, we agree with the
*1187
district court that our courts have jurisdiction to entertain this action. Both the district court and we have jurisdiction because this is an appeal from an action by the Tribe under 28 U.S.C. § 1362 to challenge a state imposed tax.

. The Tribe points with approval to 25 U.S.C. § 2710(d)(4), which states that "nothing in this section shall be interpreted as conferring upon a State or any of its political subdivisions authority to impose any tax, fee, charge, or other assessment upon an Indian tribe.” However, as discussed above, the tax in question has been imposed upon the non-Indian outfit Helix Electric and not on the Tribe itself.
. We agree with the Board that the compact entered into by the Tribe and the State does not bear on our analysis here.
