OPINION
Plaintiffs, in-state and out-of-state retail natural gas suppliers that market and sell *1096 natural gas to Ohio consumers and one of their Ohio customers, sued Ohio’s Tax Commissioner, Richard Levin. They alleged that Ohio’s tax scheme is discriminatory and thus unconstitutional under either the Commerce Clause or Equal Protection Clause because four local natural gas distribution companies benefit from certain tax exemptions and exclusions that they do not benefit from, despite their similar situations. But the district court granted the Commissioner’s motion to dismiss for lack of subject matter jurisdiction, reasoning that, while the Tax Injunction Act, 28 U.S.C. § 1341, did not bar plaintiffs’ claims, general principles of comity and federalism did. This latter conclusion was incorrect, and we therefore reverse and remand.
I.
Plaintiffs Commerce Energy, Inc. (which does business as Commerce Energy of Ohio, Inc.) and Interstate Gas Supply, Inc. are retail natural gas suppliers who market and sell natural gas to Ohio consumers. 1 Plaintiff Gregory Slone is an Ohio citizen who purchases natural gas from these retail suppliers. The plaintiff gas suppliers compete with local natural gas distribution companies who market and sell gas to Ohio consumers. These companies, unlike the plaintiffs, also own and operate distribution pipeline networks to deliver gas. While the plaintiff retail suppliers pay fees to use the distribution pipelines owned by the local gas distribution companies, the four local natural gas distributors are exempt from state and county sales and use taxes on their natural gas sales and instead pay a gross receipts excise tax that is lower than the taxes that retail suppliers pay. According to рlaintiffs, Ohio law also excludes these local distributors from commercial activities taxes on taxable gross receipts. Finally, plaintiffs also challenge Ohio tax provisions that exclude sales of natural gas between local distributors from gross receipts taxes that the plaintiffs are subject to when they purchase natural gas from the local gas distributors.
The plaintiffs sued under the Declaratory Judgment Act, 28 U.S.C. §§ 2201-02, rеquesting that the district court declare these exclusions and exemptions unconstitutional and enjoin their application. The defendant Tax Commissioner responded by moving to dismiss these claims under Fed.R.Civ.P. 12(b)(1) for lack of subject matter jurisdiction. The court dismissed plaintiffs’ complaint, reasoning that general principles of comity and federalism barred their claims. Plaintiffs appeal.

This Court reviews de novo the dismissal оf a complaint under FED. R. CIV. P. 12(b)(1) for lack of subject matter jurisdiction.

The first issue is whether the district court properly ruled that the Tax Injunction Act did not bar plaintiffs’ challenges to the constitutionality of Ohio’s natural gas taxation scheme. The Act directs federal courts not to “enjoin, suspend or restrain the assessment, levy or collection of any tax under State law where a plain, speedy, and efficient remedy may be had in the courts of such State.” 28

It thus deprives federal courts of jurisdiction to hear certain challenges to state tax schemes.
California v. Grace Brethren Church,
The Tax Commissioner replies that if plaintiffs are successful then state tax revenues could theoretically decrease in the future because the natural gas distribution companies could possibly file a future lawsuit seeking to enjoin the imposition of other taxes, and, if that future lawsuit succeeded, tax revеnues would decrease. This argument is strained, to say the least. Indeed, we recently rejected it: “The Act does not strip federal courts of jurisdiction over all claims that might, after this or that happens, have
some
negative impact on local revenues; it strips jurisdiction over claims seeking to enjoin the collection of State
‘tax
revenue.’”
BellSouth Commc’ns, Inc. v. Farris,
IV.
Notwithstanding the Act, the district court went on to rule that principles of comity and federalism barred plaintiffs’ claims. These principles reflect a “scrupulous regard for the rightful independence of state governments which should at all times actuate the federal courts” and thus they sometimes bar federal challenges to state taxation where the Act would not.
Fair Assessment in Real Estate Ass’n, Inc. v. McNary,
Nevertheless, in
Hibbs,
the Supreme Court — without disapproving of
Fair
Assessment’s core holding — stated that it has “relied upon ‘principles of comity’ ... tо preclude original federal-court jurisdiction
only
when plaintiffs have sought district-court aid in order to arrest or countermand state tax collection.”
Hibbs,
A.
Yet there is a circuit split. The district court heavily relied on
DIRECTV v. Tolson,
Other circuits disagree. The Seventh Circuit, for instance, has reconciled these cases by holding that
Fair Assessment
cannot bar each and every challenge to a state’s taxation scheme because
Hibbs
“re-strictfs] comity to cases that could tie up rightful tax revenue.”
Levy v. Pappas,
When a plaintiff alleges that the state tax collection or refund process is singling her out for unjust treatment, then the Act and comity bar the federal action, as in Fair Assessment. When a plaintiff alleges that the state tax collection or refund process is giving unfair benefits to someone else, then according to Hibbs the Act and comity are not in play.

at 762. Similarly, the Ninth Circuit, in
Wilbur v. Locke,
Animating these courts’ disagreement with the Fourth Circuit are twin concerns. First, a sweeping reading of
Fair Assessment
runs squarely against
Hibbs’s
instruction that comity guts federal jurisdiction only when plaintiffs try to thwart tax collection.
Hibbs,
B.
The Seventh and Ninth Circuits have the more persuasive view. And, even independent of its language,
Hibbs’s
logic also cоmpels us to reject the approach endorsed by the district court and the Fourth Circuit. In
Hibbs,
the Supreme Court affirmed
in toto
a Ninth Circuit decision that — along with holding that the Act did not bar plaintiffs’ claims — had specifically addressed and rejected comity as grounds for dismissal. In fact, two Ninth Circuit judges would have voted to rehear that case en banc because they believed that the claims were barred by comity.
Winn v. Killian,
More importantly, the
Hibbs
Court stated that barring the claims before it would have been inconsistent with a series of prior Supreme Court cases reviewing challenges to state tax systems that had no jurisdictional infirmities.

To support the idea that comity and federalism principles bar vast swaths of state-tax challenges, the Tax Commissioner and the district court both cite and heavily rely upon this Court’s
pre-Hibbs
decision,
In re Gillis,
Indeed, we cannot resolve this case with abstract generalizations about nontextual constitutional principles of comity and federalism. And though we emphatically reject the view that these principles broadly bar from federal court nearly every state-tax challenge, we also cannot make all-encompassing decrees regarding how principles of comity and federalism will always apply; they are merely principles. To determine whether comity and federalism preclude jurisdiction over state taxation claims, courts must determine whether the relief requested in the pleadings would significantly intrude upon traditional mаtters of state taxation such that dismissal is necessary. Thus, the difference between this ease and Gillis concerns the degree to which the claims and relief requested would intrude upon a state’s power to organize, conduct, and administer its tax scheme. In Gillis, the plaintiffs went too far; here, they have not.
In
Gillis,
the district court broadly certified a plaintiff class consisting of every single Kentucky citizen who owned taxable property and whose property was assessed via the challenged methods, and it had certified a defendant class of “all property valuation administrators of counties in which taxable property owned by coal, oil, or gas interests is located.”
Gillis,
D.
Finally, at oral аrgument, the Commissioner contended that if the plaintiffs’ claims are ultimately successful, hundreds of thousands of Ohio consumers might see their taxes rise because in-state natural gas companies would pass any tax increase to their consumers. As a result, he argues that comity requires dismissal. We reject *1101 this argument for three reasons. First, the issue was not briefed, so we cannot take judicial notice of so complеx an ipse dixit from the Commissioner. While economists agree that it is people and not corporations in the abstract that bear tax burdens, they disagree on who ends up footing this bill and in what proportion. 5 Some economists have argued that consumers pay all corporate taxes in the form of higher prices. Others have argued instead that the tax is borne by shareholders because supply and demand diсtates that the prices of the underlying products must have already been set to maximize profits before the tax was imposed, and so any increase in prices would decrease demand; thus, shareholders bear the cost as a tax on equity capital. Or, in what seems to be the modern trend, yet other economists argue that the corporate tax burden is shared in some proportion not only by consumers and shareholders, but also by workers. This is because capital is mobile and it will flow to other investments that produce higher returns after taxes when a new tax is imposed because the imposition of new taxes lowers an activity’s expected after-tax return. With less capital stock due to this capital flight, the workers become less productive and therefore earn lower wages. The point is that wе must not thrust ourselves into the middle of this economic debate by blindly accepting the Commissioner’s theory.
The second reason is that, in the context of whether a state tax challenge is barred from federal court by principles of comity and federalism, the Commissioner’s argument is “heads I win, tails you lose.” Both parties agree that if plaintiffs’ success were sure to lead to a decrease in state taxes, thеn a federal forum would be inappropriate.
Hibbs,
Third and finally, even if the Commissioner’s theory that any tax burden would pass directly to Ohio consumers were correct, that would not alter our conclusion that the plaintiffs’ claims are not barred by comity concerns. The Commissioner’s argument seems to be thаt plaintiffs’ challenges automatically create an impermissible burden on comity and federalism because corporate taxes are allegedly passed directly to consumers. But the fact that it *1102 might burden consumers cannot be enough: the Supreme Court has never intimated that challenges to discriminatory personal or consumption taxes may not, as a class, be heard in federal court so long as doing so would not otherwise significantly burden comity and federalism. 6 Thus, a possible injunction against the tax breaks challenged here would not imper-missibly burden state taxation.
V.
In this case we reject an excessively expansive reading of the older cases discussing comity as urged upon us by the Commissioner because that reading would render an Act of Congress entirely superfluous, would ignore the Supreme Court’s directive that comity strips jurisdiction “only when plaintiffs have sought district-court aid in order to arrest or countermand state tax collection,”
Hibbs,
For the above reasons, we REVERSE the district court and REMAND for further proceedings.
Notes
. Bеcause this case arises on a motion to dismiss, this Court must assume that all facts asserted in plaintiffs’ complaint are true.
. The parties agree that there is an adequate state-court remedy available.
. For support, the Commissioner also cites
Colonial Pipeline Co. v. Collins,
. In fact, the
Fair Assessment
Court did not purport to go as far as the Fourth Circuit interpreted. The
Fair Assessment
Court noted that it "needfed] not decide ... whether the comity spoken of would also bar a claim under § 1983 which requires no scrutiny whatever of state tax assessment practices, such as a facial attack on tax laws colorably claimed to be discriminatоry as to race.”
Fair Assessment,
. The authorities are mixed. See, e.g., Richard A. Posner, Economic Analysis of Law 706 (Aspen Publishers, 3d ed. 2007) ("The burden of [corporate taxes] is normally shared between consumers and shareholders.”); Harvey S. Rosen, Public Finance, (McGraw-Hill/Irwin, 6th ed.2002); Joseph E. Stiglitz, Economics of the Public Sector, (Norton, 2d ed.1988); William C. Randolph, International Burdens of the Corporate Tax, Congressional Budget Office Working Paper (2006) ("domestic labor bears slightly more than 70 percent of the burden of the corporate income tax.”), available at http://www.cbo.gov/doc. cfm?index=7503; Gregory N. Mankiw, The Problem With the Corporate Tax, N.Y. Times, June 1, 2008 ("The ultimate payers of the corporate tax are those individuals who have some stake in the company on which the tax is levied. If you own corporate equities, if you work for a corporation or if you buy goods and services from a corporation, you pay part of the corporate ... tax.”).
. Moreovеr, the fact that some tax costs might affect "hundreds of thousands of consumers” is a red herring because, even if true, it tells us nothing about the magnitude of the cost or burden — all costs passed on to prices are spread among all consumers, yet that cost might still be quite small in the aggregate. Indeed, in our above analysis we already determined that plaintiffs' requested relief would not, in sum, impermissibly burden state taxation, and whether that cost is shared by shareholders, consumers, or workers must be irrelevant. The inquiry is about magnitude; it's not a headcount.
