Which ACA premium tax credits are scheduled to expire at the end of 2026 and what do they cover?

Executive summary
The temporary “enhanced” premium tax credits (PTCs) — the ARPA/IRA-era expansions that capped premiums and extended subsidies above 400% of the federal poverty level — are scheduled to expire at the end of 2025, removing those enhancements for the 2026 plan year [1] [2]. If not renewed, enrollees would see average net Marketplace premiums more than double (a 114% rise from $888 to $1,904 on KFF’s estimate) and millions could lose coverage, with analyses projecting uninsured increases of roughly 3.8–4.8 million people in 2026 [2] [3].
1. What is expiring: the “enhanced” part of the premium tax credit
The provision set to lapse is not the ACA’s original premium tax credit itself, but the expansions adopted under the American Rescue Plan Act and extended by later legislation that made subsidies more generous and widened eligibility (including those above 400% of FPL). Reporting and policy briefs describe these as “enhanced” PTCs that expire at the end of 2025, reverting subsidy formulas and income caps to pre‑enhancement rules in 2026 absent Congressional action [1] [4].
2. What those enhancements covered — lower caps and new eligibility
The enhancements did two principal things: they reduced the maximum share of income any enrollee must pay toward a benchmark plan (for many capping premiums at or below 8.5% of income and much lower for lower incomes) and they extended subsidy eligibility to people with incomes above 400% of the federal poverty level who previously were ineligible. Together those changes increased the dollar amount of PTCs and blocked very high premium shares for middle‑income enrollees [1] [5].
3. How the disappearance changes what people pay
Analysts show concrete, large cost shifts if enhancements end. KFF’s modeling finds average net Marketplace premiums would rise by about 114% (from $888 in 2025 to an estimated $1,904 in 2026) and gives examples — e.g., a 60‑year‑old couple at roughly 402% of FPL could see annual premiums jump into the tens of thousands, instead of being limited to about 8.5% of income under enhanced rules [2] [1].
4. Who bears the biggest burden
The burden is uneven. People with incomes just above 100%–150% of FPL and many in the 150%–250% range who benefited from zero or very low premiums would see sizeable increases; enrollees over 400% of FPL who gained new eligibility will lose subsidies entirely and older enrollees in high‑cost states face the steepest dollar hits [1] [6].
5. Broader market and economic effects flagged by analysts
Beyond household bills, think tanks and analysts warn of market ripple effects: insurers have baked anticipated expiration into rate filings, adding several percentage points to proposed 2026 rate increases; projections from CBO, Urban Institute and others estimate millions more uninsured and substantial increases in uncompensated care and even job impacts across the economy [7] [3] [8].
6. Disagreement and political context
Sources document political contestation: some lawmakers and analysts press for short‑term extensions or permanent reform; others emphasize budget tradeoffs. Health Affairs and reporting note Senate and White House maneuvering on extensions and proposals to buy time for broader negotiations, reflecting competing priorities between limiting federal spending and avoiding dramatic premium shocks [9].
7. What the sources don’t say (limits of current reporting)
Available sources do not mention a finalized Congressional extension enacted after the cited pieces; they also do not provide a single authoritative count of exactly how many people will enroll or disenroll in 2026 if enhancements lapse — estimates vary by model and scenario [3] [1]. State‑specific insurer decisions will further shape final 2026 premiums [7].
8. Bottom line for consumers and policymakers
The expiring elements are the extra generosity and expanded income eligibility layered onto the ACA’s original premium tax credit: lower required contribution caps and subsidies for those above 400% FPL. If Congress does nothing, analyses predict steep premium increases for millions and large coverage losses; if policymakers act, targeted renewals or redesigns could blunt those effects, but debates over cost, scope and duration remain unresolved [1] [2] [3].
