More than a decade after its enactment, tens of millions of people nationwide rely on coverage options created through the Affordable Care Act of 2010 (ACA). The law has survived multiple court challeges at the U.S. Supreme Court and repeated attempts by Republicans in Congress to repeal it. Subsequent legislation has scaled back some aspects of the law and expanded others, including by the COVID-19 relief bill, the American Response Plan Act of 2021. This page highlights relevant analysis about the ACA and proposed and enacted changes to it..

How Marketplace Costs and Premiums will Change if Rescue Plan Subsidies Expire

While the COVID-19 relief legislation passed earlier this year provides greater subsidy assistance through 2022, Democrats in Congress are currently considering making the temporary federal help permanent or extending it as part of their planned budget reconciliation legislation.
