6 agrees on at least one thing. Whether a State treats similarly situated state and federal employees differently depends on how the State has defined the favored class. See id., at 817. So if the State defines the favored class by reference to job responsibilities, a similarly situated federal worker will be one who performs comparable duties. But if the State defines the class by reference to some other criteria, our attention should naturally turn there. If a State gives a tax benefit to all retirees over a certain age, for example, the comparable federal retiree would be someone who is also over that age.

So how has West Virginia chosen to define the favored class in this case? The state statute singles out for preferential treatment retirement plans associated with West Virginia police, firefighters, and deputy sheriffs. See W. Va. Code Ann. §11–21–12(c)(6) (Lexis 2017). The distinguishing characteristic of these plans is the nature of the jobs previously held by retirees who may participate in them; thus, a similarly situated federal retiree is someone who had similar job responsibilities to a state police officer, firefighter, or deputy sheriff. The state trial court correctly focused on this point of comparison and found no “significant differences” between Mr. Dawson’s former job responsibilities as a U. S. Marshal and those of the state law enforcement retirees who qualify for the tax exemption. App. to Pet. for Cert. 22a. Nor did the West Virginia Supreme Court of Appeals upset this factual finding. So looking to how the State has chosen to define its favored class only seems to confirm that it has treated similarly situated persons differently because of the source of their compensation.

Of course, West Virginia sees it otherwise. It accepts (for now) that its statute distinguishes between persons based on their former job duties. It accepts, too, the trial court’s finding that Mr. Dawson’s former job responsibilities are materially identical to those of state retirees who
