Congress is reviewing whether to extend the enhanced Affordable Care Act subsidies before the December 31 deadline. If the temporary assistance expires, millions of Americans could face higher health insurance premiums in 2026.
WASHINGTON, D.C. – Millions of Americans may see their health insurance bills rise next year as Congress approaches a year-end deadline to decide the future of the Affordable Care Act’s enhanced premium tax credits. The temporary subsidies, expanded during the pandemic, are scheduled to expire on December 31, 2025, unless lawmakers agree on an extension.
The Affordable Care Act, widely known as Obamacare, reshaped the nation’s health insurance system when it took effect in 2010. It expanded access to coverage, created online Marketplaces, and introduced new consumer protections. More than 24 million people selected Marketplace plans for 2025, the highest enrollment since the program began.
Who Benefits Most From the ACA
The law has provided significant financial help to lower and moderate income households. The enhanced tax credits limit how much consumers pay for a benchmark Marketplace plan, with larger reductions for families with fewer resources. People with preexisting medical conditions receive guaranteed access to coverage at the same price as healthier enrollees. Young adults are allowed to stay on their parents’ plans until age 26.
Marketplace plans must cover essential health benefits, including hospitalization, maternity care, prescription drugs, mental health services, and preventive care. For many families, the ACA has made coverage more comprehensive and more affordable than what was widely available before 2010.
Who May Pay More if Subsidies Expire
If Congress does not extend the enhanced subsidies, premiums could rise significantly for many Marketplace customers beginning in 2026. Analyses by KFF, which stands for Kaiser Family Foundation and is a nonprofit and nonpartisan health policy research organization, show that older adults and people in higher cost states would likely see the largest increases.
A major concern involves people who earn too much to qualify for financial assistance once the temporary rules end. Under earlier ACA formulas, subsidy eligibility typically stops at about 400 percent of the federal poverty level. That is about sixty thousand dollars a year for a single adult and about one hundred twenty thousand dollars for a family of four. Households above these levels must pay the full, unsubsidized price of insurance, which in some regions can range from seven hundred dollars to more than one thousand dollars per month for a single adult.
Consumers who do not receive subsidies, especially in areas with limited insurer competition, often report that Marketplace plans feel expensive even with standardized benefits and protections.
Congress Debates the Next Steps
Negotiations over the future of the subsidies have shifted to the Senate Finance Committee. Democratic members generally support renewing the current subsidy structure to prevent sudden cost increases. Some Republican members favor reinstating earlier income limits, requiring minimum premium contributions, or adding new policy conditions related to ACA coverage rules.
Any agreement would require bipartisan support to meet the Senate’s sixty vote threshold and would also need approval in the House.
President Donald Trump has recently questioned whether the enhanced subsidies should continue and has suggested that Congress consider alternative approaches. The administration has not released a detailed replacement plan.
How Households Could Be Affected
Marketplace enrollees receive the premium tax credit in advance each month, which lowers their insurance bill. If the enhanced credits expire, those reductions will shrink or end, and out of pocket premiums will rise when 2026 coverage takes effect.
Older adults who are not yet eligible for Medicare, people in rural areas, and residents of states that did not expand Medicaid would likely face some of the greatest financial pressure. In non expansion states, many low income adults remain in a coverage gap because they earn too little for Marketplace subsidies but do not qualify for Medicaid under state rules.
Public Watching Closely
National polling from KFF shows strong public interest in what happens next. Health care costs remain one of the most common financial concerns for many Americans.
As Congress considers its options, the future of the ACA subsidies will determine how much millions of households pay for health insurance in 2026 and how stable the individual insurance markets remain.
