Opinion of the Court
As discussed above, Congress based the Affordable Care Act on three major reforms: first, the guaranteed issue and community rating requirements; second, a requirement that individuals maintain health insurance coverage or make a payment to the IRS; and third, the tax credits for individuals with household incomes between 100 percent and 400 percent of the federal poverty line. In a State that establishes its own Exchange, these three reforms work together to expand insurance coverage. The guaranteed issue and community rating requirements ensure that anyone can buy insurance; the coverage requirement creates an incentive for people to do so before they get sick; and the tax credits—it is hoped—make insurance more affordable. Together, those reforms "minimize . . . adverse selection and broaden the health insurance risk pool to include healthy individuals, which will lower health insurance premiums." 42 U. S. C. §18091(2)(I).
Under petitioners’ reading, however, the Act would operate quite differently in a State with a Federal Exchange. As they see it, one of the Act’s three major reforms—the tax credits—would not apply. And a second major reform—the coverage requirement—would not apply in a meaningful way. As explained earlier, the coverage requirement applies only when the cost of buying health insurance (minus the amount of the tax credits) is less than eight percent of an individual’s income. 26 U. S. C. §§5000A(e)(1)(A), (e)(1)(B)(ii). So without the tax credits, the coverage requirement would apply to fewer individuals. And it would be a lot fewer. In 2014, approx-

That is particularly true when, as here, "the Act is far from a chef d'oeuvre of legislative draftsmanship." Ibid. Because the other provisions cited by the dissent are not at issue here, we do not address them.
