ACA Subsidy Cliff 2026: Enhanced Premium Tax Credits Expired — Premiums Could Double for 15 Million Enrollees

# ACA Subsidy Cliff 2026: Enhanced Premium Tax Credits Expired — Premiums Could Double for 15 Million Enrollees

> **Quick answer:** The enhanced ACA premium tax credits that kept Marketplace health insurance affordable since 2021 expired on December 31, 2025. Congress's One Big Beautiful Bill Act (OBBBA) does not extend them. KFF analysis confirms marketplace premiums have more than doubled on average for enrollees above 400% of the federal poverty level — and in states like West Virginia and Wyoming, some enrollees are seeing increases of 1,000% or more. Approximately 15 to 22 million Americans are affected, and the CBO projects that 4.2 million people will lose insurance entirely as a direct result.

The ACA subsidy cliff just landed — and it hit harder than most people were told to expect. The enhanced premium tax credits that made Marketplace health insurance genuinely affordable for millions of Americans since 2021 expired at the end of 2025. Congress had the chance to extend them. The legislation that passed — the One Big Beautiful Bill Act — chose not to. For the 15 to 22 million enrollees who depended on those enhanced credits, the result is a premium shock that researchers at KFF describe as a "more than doubling" of what many households owe each month.

## What the ACA Subsidy Cliff Is and Why It Returned in 2026

The "subsidy cliff" is not new — it is a structural feature baked into the original Affordable Care Act. Under original ACA rules, premium subsidies phased out entirely at 400% of the federal poverty level (FPL). In 2026, 400% FPL equals roughly $62,000 for a single individual and $84,600 for a couple. Any household earning even $1 above that line received zero premium assistance, regardless of how expensive coverage was in their state.
