Enhanced Premium tax credits

2025 KFF Marketplace Enrollees Survey

If the amount they pay in premiums doubled, about one in three enrollees in Affordable Care Act Marketplace health plans say they would be “very likely” to look for a lower-premium Marketplace plan.

An image of text is an excerpt form Larry Levitt's quick take which reads, "While the enhanced ACA premium tax credits expire at the end of this year, there is no absolute drop-dead date for extending them. ACA enrollees would welcome premium relief whenever it comes."

There is No Drop-Dead Date for an ACA Tax Credit Extension, But Coverage Losses Will Mount as the Clock Ticks

A discharge petition in the House paves the way for a vote on a three-year extension of the tax credits, which would provide ACA enrollees premium relief whenever it comes. While there is still time to extend the enhanced tax credits, with each passing day, more and more ACA Marketplace enrollees are going to drop their health insurance when faced with eye-popping increases in their premium payments, writes KFF’s Larry Levitt.

Competition Has Increased in the Individual Market But Fallen in Fully Insured Group Markets

Commercial health insurance markets remain highly concentrated across coverage types.

  • The ACA’s Basic Health Program Option: Federal Requirements and State Trade-Offs

    Report

    The Patient Protection and Affordable Care Act (ACA) gives states the option to implement a Basic Health Program (BHP) that covers low-income residents through state-contracting plans outside the health insurance marketplace, rather than qualified health plans (QHPs). In March 2014, the Centers for Medicare & Medicaid Services (CMS) issued final regulations on the requirements for a BHP and the methodology for calculating federal payments to states. States can choose to implement BHP beginning in 2015. This report summarizes these federal policies, including the requirements for BHP as well as the methodology for determining federal BHP payments. It then analyzes the key trade-offs facing states as they decide whether and, if so, how to implement BHP, with a particular focus on the impact of BHP on state budgets and the size, stability, and risk level of state marketplaces.
