The Implications of King v. Burwell: Highlights from Three Analyses of the Consequences of Eliminating ACA Tax Credits in 34 States

Capitol Building in Washington D.C.

Research shows ruling in King v. Burwell could have far-reaching effects on health spending and the number of uninsured.


The Issue

On March 4, the Supreme Court will hear oral arguments in King v. Burwell on the constitutionality of the Affordable Care Act's tax credits. If the Supreme Court rules ACA tax credits are unconstitutional in 34 states, health spending and the number of uninsured will be impacted.

Key Findings

  • If the Court finds for King, 9.3 million people would lose tax credits, with two-thirds of these people becoming uninsured

  • Health care spending would fall by at least 35 percent (projected loss of $9.7 billion)
