Enhanced premium subsidies were first made available under the American Rescue Plan Act and extended until the end of 2025 under the Inflation Reduction Act. This analysis shows the impact that enhanced subsidies have had on enrollment and premium payments, and the potential implications if the enhanced subsidies expire.
Most customers with coverage through Affordable Care Act's marketplaces will face big premium increases next year if Congress doesn’t extend the temporary enhanced tax credits included in the American Rescue Plan Act (ARPA) of 2021. If the outcome isn’t clear by summer, fall open enrollment could be a mess.
This chart examines individual market enrollment data from 2011 through 2025, when enrollment reached a record high of 25.2 million people. Affordable Care Act (ACA) Marketplace enrollment increased following the enactment of enhanced premium tax credits in 2021, as more individuals became eligible for subsidies.
The Health Insurance Marketplace Calculator, updated with 2020 premium data, provides estimates of health insurance premiums and subsidies for people purchasing insurance on their own in health insurance exchanges (or “Marketplaces”) created by the Affordable Care Act (ACA). With this calculator, you can enter your income, age, and family size to estimate your eligibility for subsidies and how much you could spend on health insurance.
Ahead of the annual Affordable Care Act (ACA) open enrollment period, the time during which consumers can shop for health plans or renew existing coverage, KFF has updated its Health Insurance Marketplace Calculator and its searchable collection of more than 300 Frequently Asked Questions about open enrollment, the health insurance marketplaces and the ACA.
In his first column for the new year, KFF CEO Dr. Drew Altman analyzes President Trump’s “make a deal” approach to health care. He explains that while the president doesn’t have a health reform plan, or even “concepts of a plan,” or a replacement for the ACA, he does have a distinctive set of tactics that features one-off deals with the health care industry that are more like “health policy by transaction.” He writes that the deals “even do some good,” but “don’t change the long-term incentives of the health care companies that participate in the deals,” and a big question is “whether they have staying power.”
This data note examines how the expiration of the ACA's enhanced premium tax credits could affect the out-of-pocket portion of premiums for different households.
As Democrats push for an extension of the ACA’s enhanced premium tax credits, new data from KFF show the extent to which states won by Trump in 2024 have come to rely on the ACA Marketplaces and the tax credits, which make health care coverage more affordable for low- and middle-income Marketplace enrollees.
Conservatives obviously don't like what they call "Obamacare" because they think it expands the role of government too much and spends too much money.
The Affordable Care Act (ACA) requires private health insurers to cover recommended preventive services such as colonoscopies without any patient cost-sharing. This report finds that confusion over whether colon cancer screenings are preventive care or treatment means patients sometimes receive unexpected bills for the procedure. The report examines cost-sharing practices for colorectal screenings through interviews with experts and officials in the medical and insurance industries.
