Earlier this year the U.S. Supreme Court heard arguments in King v. Burwell, a case critical to the future of the Affordable Care Act (ACA, or so-called Obamacare). Readers interested in the details of the case should find them elsewhere. Suffice it to say here that the case concerns whether individuals can receive tax credits for buying health insurance on exchanges established by the federal government, though the text of the ACA indicates such subsidies are provided for those buying coverage through an “exchange established by the State.”

The case has the potential to invalidate substantial subsidies now being provided by federal taxpayers to millions of Americans using federal exchanges in 37 different states. Given the uncertainty created by the pending case, legislators on both sides of the aisle are considering how to react to various possible scenarios arising from a court decision. The House and Senate each recently passed budget resolutions allowing budget targets to be revised in the event of subsequent legislation modifying the ACA. The Senate resolution specifies that such legislation must be deficit-neutral.
