Millions of Americans who earned above 400 percent of the federal poverty line just lost their Affordable Care Act premium subsidies entirely. Congress temporarily removed the income cap on premium tax credits for tax years 2021 through 2025, but that expansion expired at the end of 2025. Starting with the 2026 plan year, households above the 400 percent threshold receive zero federal help with Marketplace premiums, and the maximum share of income anyone is expected to pay for a benchmark plan rises to 9.96 percent.
How the 400 percent FPL cliff returned for 2026
For five years, a household earning $130,000 or more could still qualify for at least some premium assistance on HealthCare.gov. That changed when the enhanced credits, first enacted through the American Rescue Plan and extended by the Inflation Reduction Act, reached their statutory sunset. The IRS confirms that for tax years 2021 through 2025, Congress temporarily expanded premium tax credit eligibility by eliminating the 400 percent FPL cap. With the expansion gone, the original ACA subsidy structure snaps back into place for 2026.
The practical result is abrupt. A family of four earning just above the cutoff now owes the full sticker price for a silver-tier plan. The IRS has published Rev. Proc. 2025-25, which sets the 2026 applicable percentage at 9.96 percent, the ceiling that determines how much of household income can go toward the benchmark plan before subsidies kick in. Households below 400 percent of the poverty line still receive credits scaled to income, but everyone above that line faces the unsubsidized premium with no federal offset.
The federal poverty guidelines establish the dollar thresholds used to calculate where each household falls on the FPL scale. Those figures, updated annually by the Office of the Assistant Secretary for Planning and Evaluation, feed directly into the eligibility formulas that exchanges and the IRS apply when determining credit amounts. For 2026, any household whose modified adjusted gross income lands above four times the relevant guideline figure is treated as ineligible for premium tax credits, no matter how high local premiums run.
IRS and CMS data show the scope of the subsidy loss
The Marketplace fact sheet from the Centers for Medicare & Medicaid Services (CMS) details average premiums and financial assistance levels for enrollees who still qualify for credits. Those numbers, however, exclude the population above 400 percent FPL, which now receives zero assistance. CMS also publishes open enrollment public-use files that break down enrollment by household income as a percentage of FPL, offering the closest available window into how many people sit in the newly unsubsidized band.
IRS data on premium tax credit reconciliation will eventually show how many households lose eligibility altogether starting with tax year 2026. During the years when the cap was suspended, many middle- and upper-middle-income families used credits to keep their net premiums under a fixed share of income. With the cap restored, those same households must either absorb the full premium, downshift to leaner coverage, or exit the individual market entirely.
The impact is likely to be most acute in regions with high underlying premiums, such as rural areas with limited insurer competition and older risk pools. In those markets, the sticker price of a benchmark silver plan can approach or exceed a typical mortgage payment. For a 60-year-old buying coverage alone, being just one dollar over the 400 percent line can mean losing hundreds of dollars per month in help.
What it means for consumers and marketplaces
The return of the subsidy cliff creates sharp marginal tax effects and difficult choices for consumers. Financial planners now have a stronger incentive to help clients manage their modified adjusted gross income to stay just under the 400 percent threshold where possible, using retirement contributions, health savings accounts, or timing of income. Households that cannot reduce income may look for lower-cost bronze plans, accept higher deductibles, or consider going uninsured if they judge premiums unaffordable.
For the marketplaces themselves, the loss of higher-income subsidized enrollees could slightly shrink the risk pool. If relatively healthy, unsubsidized consumers leave first, average claims costs could rise, putting upward pressure on premiums for those who remain. Regulators will be watching closely during the 2026 open enrollment period to see whether plan participation or premium trends diverge from recent years.
Policy context and possible next steps
The broader policy context sits within the U.S. Department of Health and Human Services, which oversees ACA implementation, CMS operations, and the annual poverty standards. Through its main department portal, HHS has emphasized coverage gains achieved under the ACA and the temporary expansions, but the agency must now administer the law as written with the 400 percent cap back in force.
Any change to that cap would require new legislation. Lawmakers could choose to restore the temporary structure that tied premium contributions to a sliding share of income for all households, or they could design a more gradual phaseout to soften the cliff. Until then, consumers above 400 percent FPL will need to budget for the full, unsubsidized cost of coverage and use the existing Marketplace tools to compare plan options carefully.
As the 2026 plan year unfolds, data from CMS and the IRS will clarify how many people lose subsidies, how many downgrade coverage, and whether the coverage gains of the past several years begin to erode. For now, the return of the 400 percent FPL cliff marks a clear dividing line in the ACA’s promise of affordable coverage: below the line, substantial federal help remains; above it, households are once again on their own.
