A wave of health insurance renewal notices is landing this fall with premiums well above what many households paid a year ago, and the reason traces back to a decision that already took effect, not one still pending. The extra financial help that had been holding down Affordable Care Act marketplace premiums since 2021 lapsed on December 31, 2025, and its absence is already built into the bills people are opening in 2026. For a household planning a health insurance budget, that distinction matters: the subsidy did not quietly wind down at some point this year, and it is not scheduled to end later this year either. It already ended, months ago, and next year’s premiums are being built on top of that change.
The Subsidy Boost Expired December 31, 2025, Not This Year
The credits at issue are the enhanced premium tax credits, first created under the American Rescue Plan Act in 2021 and later extended by the Inflation Reduction Act. They increased the size of ACA marketplace subsidies and extended eligibility to households earning more than four times the federal poverty level, who previously received no premium help at all. Insurer rate filings now cite a specific expiration point for that assistance, and it is not the date a lot of circulating advice assumes.
That expiration date matters because a fair amount of advice still treats the cutoff as the end of this year, 2026, rather than the end of last year. It is not. The Peterson-KFF Health System Tracker’s review of those filings confirms the enhanced credits already expired on December 31, 2025, and have been gone for the entire 2026 plan year — every premium a marketplace enrollee has paid since January has reflected their absence. Base ACA subsidies for lower-income enrollees still exist under permanent law; it is only the enhancement, and the households above four times the poverty line who relied on it entirely, that lost help.

Premium Payments After Subsidies Rose 58 Percent This Year
The clearest sign of what changed shows up in what enrollees actually pay. Average premium payments after subsidies rose 58 percent in 2026 compared with the prior year, as smaller or nonexistent tax credits shifted more of the sticker price back onto enrollees. Some of that increase reflects people voluntarily downgrading to bronze plans with higher deductibles to hold the monthly payment down, a trade that lowers the visible premium but raises the cost of actually using the coverage.
For the roughly 87 percent of 2026 marketplace enrollees who still receive some subsidy — down from 92 percent the year before — the increase is smaller than it is for the minority who lost assistance entirely, but it is not zero. Insurers are pricing in another year of these effects for 2027, on top of the ones already showing up in current bills.
Three Million Fewer Enrollees, and a Sicker Pool Left Behind
The subsidy cut had a direct effect on who stayed enrolled. Marketplace enrollment fell by roughly three million people in 2026 after the credits lapsed, and the enrollees most likely to walk away were the healthier ones with the least to lose by going without coverage. That leaves a marketplace risk pool that is, on average, sicker and more expensive to insure than it was in 2025.
The Health System Tracker analysis found insurers built an estimated four-percentage-point add-on into 2026 rates specifically to account for that shift, and they are layering a similar adjustment onto 2027 filings because they expect the pool to keep thinning as premiums climb further.
One Household’s Numbers: $316 to $546 a Month in Two Years
The Health System Tracker illustrates the shift with a concrete example: a 40-year-old in Indianapolis earning $65,000 a year, enrolled in a mid-tier silver plan. With the enhanced credits in place, that person paid $316 a month in 2025. Once the credits expired, the same plan cost $477 a month in 2026. If proposed 2027 rates are approved, the payment rises again to $546 a month — a two-year increase of $158 a month, or 41 percent, driven by the subsidy’s expiration and the rate increases that followed it.
That household is not unusual. Anyone earning more than roughly four times the federal poverty level — about $63,000 for an individual or $129,000 for a family of four — crossed the income line where the enhanced credits mattered most, and lost the most ground when they disappeared.
Insurers Are Already Pricing In Another Increase for 2027
Rate filings submitted this spring and summer show a median proposed premium increase of 15 percent for 2027 across 276 marketplace insurers in all 50 states and Washington, D.C. — the second-highest requested increase since 2018, behind only last year’s. Insurers point to rising medical costs, general inflation and healthcare labor shortages as the biggest drivers, but they separately flag the shrinking, sicker risk pool left behind by the subsidy expiration as an added factor pushing next year’s prices higher still.
The filings are not final. State regulators will review and adjust them over the summer, and the Peterson-KFF Health System Tracker plans to update its analysis once finalized 2027 rates are in, the same way it tracked finalized rates climbing to a median 20 percent for 2026 after insurers had initially proposed 18 percent.
