Enhanced ACA Subsidies Are Expiring: What It Means for Health Insurance in 2026
The door is rapidly closing on enhanced ACA subsidies, a pandemic-era lifeline that has helped millions of Americans afford health insurance. Unless Congress takes last-minute action, these expanded Affordable Care Act subsidies will officially expire on December 31, 2025, setting the stage for significantly higher health insurance costs in 2026.
For millions of U.S. families who rely on ACA marketplace health insurance, the end of enhanced subsidies could mean sharply higher monthly premiums, fewer coverage options, or losing health insurance altogether.
What Are Enhanced ACA Subsidies?
ACA subsidies, also known as premium tax credits, lower the cost of health insurance purchased through the Affordable Care Act marketplace. These credits have existed since 2014, but in 2021 they were temporarily expanded during the COVID-19 pandemic.
The enhanced ACA subsidies made health insurance more affordable by increasing tax credits, removing the income cap, and limiting how much people had to pay out of pocket for premiums. As a result, ACA enrollment surged to more than 24 million Americans in 2025, with about 93% of enrollees receiving subsidies.
These enhanced benefits are now set to expire, reverting the system back to the older, less generous subsidy structure starting in 2026.
Why the Expiration of ACA Subsidies Matters
The expiration of enhanced ACA subsidies is expected to cause one of the largest affordability shocks in the history of the Affordable Care Act. According to health policy experts, ACA insurance premiums could more than double for many enrollees once the enhanced subsidies disappear.
Analysts at KFF estimate that subsidized enrollees will see average out-of-pocket premium increases of 114% from 2025 to 2026, after accounting for both inflation and subsidy rollbacks. In many states, monthly premiums could rise by hundreds of dollars.
Impact on Health Insurance Coverage in the USA
The Congressional Budget Office (CBO) projects that ending enhanced ACA subsidies will lead to 4.2 million additional uninsured Americans. When combined with other policy and Medicaid changes, as many as 14.2 million people could lose health coverage by 2034.
This loss of coverage could disproportionately affect middle-income households, older adults, and self-employed workers who don’t receive employer-sponsored health insurance but also don’t qualify for Medicaid.
How Much Do Enhanced ACA Subsidies Cost?
Extending the enhanced ACA subsidies is expensive. The CBO estimates that a 10-year extension would cost approximately $350 billion, while increasing insurance coverage by about 3.8 million people by 2035.
Despite bipartisan discussions, political gridlock has prevented Congress from passing an extension before the December 31 deadline.
What Happens to ACA Plans in 2026?
Without enhanced ACA subsidies, consumers will face:
- Higher monthly premiums for ACA marketplace insurance
- Increased deductibles and out-of-pocket costs
- Reduced enrollment as healthier individuals opt out
- A shift toward high-deductible Bronze plans
On average, ACA marketplace premiums for 2026 are already projected to rise by 26%, even before accounting for the loss of enhanced subsidies.
What Should You Do If Your ACA Costs Increase?
If your Affordable Care Act insurance becomes more expensive in 2026, reviewing your options is critical.
Shopping around during open enrollment can help you find a plan that better fits your budget. Silver plans may still offer the best value for people who qualify for remaining subsidies, thanks to cost-sharing reductions.
If you no longer qualify for subsidies, it may be worth comparing Bronze and Gold ACA plans, as pricing can vary significantly by state and insurer. Be cautious with short-term health insurance plans, which often lack essential ACA protections.
ACA Open Enrollment Timeline
While open enrollment for January 2026 coverage ended on December 15, Americans can still enroll for February 2026 coverage through the ACA marketplace. Missing enrollment could leave you uninsured for the year unless you qualify for a special enrollment period.
How Did We Get Here?
The expiration of enhanced ACA subsidies has been a major political battleground. Although lawmakers promised votes and negotiations, no legislation has successfully cleared both chambers of Congress.
A recent government shutdown underscored how contentious the issue has become, with multiple failed attempts to extend the subsidies before their expiration.
The Bottom Line on ACA Subsidies in 2026
The end of enhanced Affordable Care Act subsidies represents a major turning point for U.S. health insurance. Millions of Americans could face higher premiums, reduced coverage, or the difficult decision to go uninsured.
If you rely on ACA marketplace insurance, staying informed, comparing plans, and understanding your subsidy eligibility will be essential in navigating the 2026 health insurance landscape.
As the deadline passes, the true impact of expiring ACA subsidies will become one of the most significant health policy stories in the United States.
