ACA Premium Tax Credits to End at Midnight, Putting Millions at Risk of Higher Insurance Costs

Enhanced subsidies created to lower monthly premiums for Americans who purchase health insurance through the Affordable Care Act (ACA) marketplace are scheduled to expire when the calendar turns to Jan. 1, 2026. The assistance, formally known as premium tax credits, currently reduces or eliminates out-of-pocket premium costs for an estimated 22 million of the 24 million marketplace enrollees.

The tax credits have been a core component of the ACA since its passage in 2010. Congress temporarily increased both the size of the subsidies and the number of people eligible for them during the COVID-19 pandemic, broadening financial relief as economic uncertainty grew. Unless lawmakers approve an extension, the pandemic-era enhancements will lapse at 11:59 p.m. on Wednesday, Dec. 31, 2025.

Political Deadlock Led to Impasse

The subsidies became a flashpoint during the record-long federal government shutdown that stretched through October and early November. Republican leaders argued that the expanded benefits went beyond the ACA’s original scope and pressed for a temporary funding bill that left the issue unresolved. Democrats insisted on maintaining the higher tax credits as part of any agreement to reopen the government, contending that millions of families would face financial harm if the assistance disappeared.

Negotiations produced a bipartisan bill that ended the shutdown in early November, but the compromise did not include language to preserve the enhanced subsidies. Eight Democratic senators joined Republicans in supporting the measure, which later cleared the House of Representatives. Party leaders said at the time that further debate on the ACA would occur before year’s end.

That debate has yet to yield a solution. Competing health-care bills introduced in the Senate earlier in December failed to advance, and the enhanced credits will terminate by law at midnight. House Minority Whip Katherine Clark and other Democratic lawmakers have criticized Republicans for inaction, warning that households will soon see premiums rise sharply.

Vote Expected in January

The House is expected to take up a Democrat-led proposal in January that would prolong the expanded subsidies for three more years. The outcome remains uncertain, and any measure would also need Senate approval and a presidential signature before taking effect.

Projected Cost Increases

Analyses from nonpartisan organizations illustrate the stakes. The Congressional Budget Office has estimated that, absent an extension, gross benchmark premiums for standard marketplace plans will rise 4.3 percent in 2026 and 7.7 percent in 2027. A separate study released in November by the KFF nonprofit health policy group calculated that consumers who currently receive financial assistance would experience average premium increases of 114 percent—jumping from $888 for annual coverage in 2025 to $1,904 in 2026.

Such increases would be felt unevenly. Eligibility for premium tax credits depends on factors including household income and geographic location. For many low- and middle-income families, the credits have meant the difference between affordable coverage and no coverage at all.

Households Brace for Higher Bills

Doug Butchart of Illinois is among those preparing for the change. His wife, Shadene, lives with amyotrophic lateral sclerosis (ALS), a progressive neurological disorder that requires ongoing medical care. Butchart said the couple’s current marketplace plan will cost more than $2,000 a month without the enhanced subsidy—an amount he called unsustainable. They have switched to a lower-tier plan but still expect significant financial strain in the coming year.

Butchart’s situation reflects a broader concern expressed by policyholders nationwide who rely on the tax credits to manage chronic conditions, pay for prescriptions and access regular physician visits. Many say they are unsure how they will absorb hundreds of dollars in additional monthly expenses.

Market Dynamics Ahead

Insurance carriers set premiums based on anticipated claims, regulatory requirements and competitive factors. The anticipated expiration of enhanced subsidies has already influenced 2026 rate filings in several states, according to industry analysts. Without the additional federal support, insurers expect a smaller pool of healthier enrollees and a higher share of individuals with costly medical needs, conditions likely to put upward pressure on prices.

Marketplace open enrollment for 2026 plans begins next fall, leaving a relatively short window for Congress to act if lawmakers wish to keep current premium levels in place. Observers note that any delay in passing an extension would complicate the work of insurers, state regulators and the federal marketplace platform.

Historical Context

The premium tax credits were originally designed to limit what households pay for a benchmark silver-tier plan to a sliding percentage of income. The pandemic-era expansion lowered those percentages and removed the upper income limit, enabling individuals earning above 400 percent of the federal poverty level to qualify for the first time. That temporary policy is now ending, returning eligibility rules to their pre-2021 parameters if no new legislation passes.

For now, millions of Americans face the prospect of higher insurance bills just as the new year begins. Whether Congress will move swiftly enough to reinstate or redesign the subsidies remains uncertain, leaving consumers, insurers and health-care providers in a wait-and-see posture as the clock approaches midnight.
