Millions of Americans who purchase their health insurance on the Affordable Care Act (ACA) marketplaces face a looming crisis as premium tax credits (PTCs) that have helped keep coverage affordable are set to expire at the end of 2025.
These enhanced subsidies, which have been in place since 2021, currently lower the cost of health insurance for over 20 million people. Unless Congress intervenes, average premiums for those who receive financial assistance could more than double, putting coverage out of reach for many and potentially leading to a surge in uninsured individuals.
The enhanced premium tax credits were introduced to make health coverage more affordable during the COVID-19 pandemic and economic recovery, significantly reducing out-of-pocket costs for middle- and lower-income Americans. However, Congress has missed several opportunities this year to extend these temporary financial protections as part of broader spending or health legislation. The Congressional Budget Office has warned that failure to renew the enhanced subsidies could result in about 4 million more uninsured Americans by 2034.
As the 2026 open enrollment period begins November 1, insurers have already begun notifying consumers of premium increases. Insurers proposed a median premium increase of around 18 percent, citing higher medical costs and the anticipated impact of the subsidy expiration on the risk pool. Without the enhanced tax credits, however, the true price increases faced by subsidized enrollees will be far more severe.
Analysis from the Urban Institute and the Center for American Progress indicates that the average premium for marketplace enrollees who rely on financial assistance will rise by approximately 136 percent nationally. In some states, such as Alaska and Mississippi, premium hikes could exceed 300 percent. For example:
- Alaska: 346% increase, rising by $909 annually
- California: 122% increase, rising by $1,000 annually
- Texas: 289% increase, rising by $459 annually
Before enhancements, the average annual premium for subsidized enrollees was around $460. Without the enhanced premium tax credits, that cost would jump to $1,087 even if consumers switch to the lowest-cost plan in their metal tier, highlighting the scale of the impending cost burden.
The amount households pay depends on their income and the specific premiums in their area, but the interactive calculators from policy organizations allow individuals to estimate their expected premium increases in the absence of subsidy extensions. This dramatic rise in premium costs could force many to choose between coverage and other essential expenses or leave the insurance market altogether, worsening health disparities and financial insecurity.
Health policy experts emphasize the urgent need for Congress to act quickly to renew or extend these enhanced subsidies to prevent millions from losing affordable coverage. Without legislative action, millions of Americans who rely on the ACA marketplaces for protection against high medical costs may face increased financial strain and decreased access to care.
The potential expiration of enhanced premium tax credits comes at a critical time when health insurance affordability remains a top concern for consumers. This situation underscores the importance of sustained policy support to maintain equitable access to health care coverage.
