Since the enhanced premium tax credits became available in 2021, ACA Marketplace enrollment has increased significantly in some red states, and 57% of enrollees now live in Republican congressional districts.
The ACA enhanced premium tax credits expanded financial assistance to more Marketplace enrollees, an expansion that was especially helpful to older middle-income enrollees, who would see the largest increases in out-of-pocket premiums if the enhanced credits expire.
A look at public opinion about the ACA and its provisions, including protections for people with pre-existing conditions and the impact of the law on families.
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.
KFF's Health Tracking Poll finds that more than three-quarters of the public say they want Congress to extend the ACA enhanced premium tax credits that are set to expire at the end of this year. If the credits do expire and the average premium more than doubles, seven in 10 of those who purchase their own insurance say they would not be able to afford premiums without significantly disrupting their household finances.
A new KFF Health Tracking Poll finds more than three-quarters (78%) of the public say they want Congress to extend the enhanced tax credits available to people with low and moderate incomes to make the health coverage purchased through the Affordable Care Act’s Marketplace more affordable.
This Health Policy 101 chapter provides an overview of the Affordable Care Act (ACA), a major reform of the U.S. health care system aimed at reducing high uninsured rates and alleviating issues like high out-of-pocket costs and coverage exclusions for preexisting conditions. The ACA significantly altered many aspects of the health system and the chapter explores its mechanisms, such as the Health Insurance Marketplaces, and the evolution of the law since its passage in 2010 to the changes in the 2025 budget reconciliation law.
KFF estimates that, if Congress allows the enhanced premium tax credits to expire at the end of this year, ACA Marketplace enrollees on average would see their premium payments more than double next year, growing by 114%, from an average of $888 in 2025 to $1,904 in 2026.
This policy watch explains how abortion coverage works in ACA Marketplace plans, state actions to include or exclude abortion coverage in these plans, and the potential impact if Congress bans abortion coverage in all Marketplace plans.
In his latest column, President and CEO Dr. Drew Altman shows how spiking premiums, which may come if the enhanced ACA tax credits are not extended, will hit people in the context of their family budgets, alongside rising costs for food, housing and utilities. For some families, their new health care costs could far exceed what they pay for food, affecting their economic security and potentially their vote.
