When open enrollment for 2026 marketplace plans began, millions of Americans who buy their own health insurance encountered a jarring reality: monthly premiums had spiked, sometimes by hundreds of dollars, even though nothing about their health or income had changed. The culprit was not a sudden surge in medical costs. It was the expiration of enhanced federal subsidies that had been shielding consumers from the full price of coverage since 2021.
For a 40-year-old single adult earning $50,000 a year, the math is stark. Under the enhanced subsidy formula that was in effect through December 2025, that person’s annual premium contribution for a benchmark silver plan was capped at roughly $4,250 (8.5% of income). Under the reverted formula now governing 2026 coverage, the cap has climbed to about $4,980 (9.96% of income), according to IRS Revenue Procedure 2025-25. That formula change alone adds approximately $730 a year. Factor in continued growth in gross benchmark premiums, which the reverted subsidy absorbs less of, and the total increase lands in the neighborhood of $2,000 annually, or about $167 more each month.
How the subsidy formula changed
The enhanced premium tax credits were created under the American Rescue Plan Act of 2021 and extended through 2025 by the Inflation Reduction Act. For tax years 2021 through 2025, the credits did two things: they capped marketplace premiums at no more than 8.5% of household income regardless of earnings, and they eliminated the longstanding income cutoff at 400% of the federal poverty level (FPL). A single adult earning $80,000 could still receive help. Someone earning $50,000 paid far less than they had before the pandemic.
Congress did not renew the expansion before it sunset on December 31, 2025. The IRS has reverted to the original ACA subsidy table, which sets the applicable percentage, the share of income a household is expected to contribute toward premiums, at 9.96% for 2026. That figure comes from the annual recalculation the IRS performs using national health expenditure projections published by the Centers for Medicare and Medicaid Services, which track the relationship between premium growth and income growth through modeling covering 2024 through 2033.
The return of the 400% FPL cliff
Perhaps the most disruptive change is the return of the income cliff. Under the original ACA structure, anyone earning above 400% of the federal poverty level receives zero premium tax credit. For a single adult, 400% of the 2025 federal poverty level is $62,600. (The Department of Health and Human Services typically updates poverty guidelines each January; the 2026 figure may be slightly higher, but the threshold has not yet been formally published for the new plan year.)
The practical effect is severe. A single adult earning $63,000 could owe the full unsubsidized premium, while someone earning $62,000 still qualifies for meaningful assistance. During the five years the enhanced credits were in place, this cliff did not exist. Its return creates a sharp penalty for modest income gains and puts marketplace coverage out of reach for many people just above the cutoff.
What federal data shows about 2026 pricing
The Centers for Medicare and Medicaid Services published plan year 2026 pricing data showing that gross benchmark premiums rose at a moderate pace. But because the enhanced credits had been absorbing most of that growth for five consecutive years, the net premium increase hitting consumers’ bank accounts is far steeper than the raw insurer price hike. Middle-income enrollees, the group that benefited most from the temporary expansion, are absorbing the largest share of the increase.
This dynamic explains why the $2,000 annual increase for a $50,000 earner is not simply the result of insurers charging more. It is the compounded effect of five years of premium growth that consumers never fully felt, now landing all at once as the federal buffer disappears.
Projected coverage losses
The Urban Institute estimated in a December 2024 analysis that 4.8 million people would lose health coverage in 2026 if the enhanced credits expired. That projection used national aggregate modeling of how consumers historically respond to premium increases. Whether actual enrollment declines match the estimate will not be clear until CMS releases 2026 effectuated enrollment data later this year.
Not everyone who drops a marketplace plan will go uninsured. Some will downgrade to cheaper bronze plans with higher deductibles. Others may qualify for Medicaid if their income falls below the threshold in the 40 states (plus Washington, D.C.) that have adopted Medicaid expansion. And a handful of state-based exchanges have explored using state funds to partially replace the lost federal credits. California’s Covered California program, for instance, has supplemented federal subsidies with state dollars in past years. But no state program operates at a scale that comes close to replacing the expired federal investment.
Where Congress stands
As of late May 2026, no legislation restoring the enhanced credits has been signed into law. Lawmakers in both chambers have introduced competing proposals during ongoing budget negotiations. Some bills call for a full restoration of the 8.5% income cap and the elimination of the 400% FPL cliff. Others propose a gradual phase-out of credits above 400% FPL rather than a hard cutoff. A smaller group of Republican members has pushed for restructuring the credits around health savings accounts.
None of these proposals has reached a floor vote in either chamber. For anyone enrolling in or renewing marketplace coverage for the 2026 plan year, the higher costs are the standing reality.
What consumers can do right now
For people already facing higher premiums, the most immediate lever is plan selection. Automatically renewing last year’s coverage almost guarantees overpaying, because plan pricing, network structures, and formularies shift every year. Switching from a silver to a bronze plan, or choosing a narrower-network option within the same metal tier, can offset part of the subsidy loss. The tradeoff is typically a higher deductible or more limited provider access.
Income projections matter more than usual this year. The premium tax credit is reconciled on the annual tax return: underestimating 2026 income can trigger a repayment obligation the following April, while overestimating it means leaving subsidy dollars on the table during the months they are needed most. The IRS guidance on the premium tax credit explains how advance payments are calculated and later trued up.
It is also worth noting that the federal individual mandate penalty remains at $0, where it has been since 2019. That means there is no federal tax penalty for going uninsured, which may factor into the decision for some consumers weighing whether to keep paying a higher premium. However, a few states, including Massachusetts, New Jersey, California, Rhode Island, and the District of Columbia, impose their own individual mandate penalties, so dropping coverage in those states carries a financial consequence beyond lost insurance.
Older adults approaching 65 should evaluate whether marketplace coverage still makes financial sense compared with Medicare. The federal Medicare website details when people can transition from marketplace plans, how late-enrollment penalties work, and what coverage gaps to watch for. With marketplace premiums now substantially higher for people in their early 60s under the reverted subsidy formula, the math may favor earlier Medicare enrollment for those who qualify.
What $167 a month actually means for middle-income workers
The numbers embedded in IRS formulas and CMS projections are not abstractions. They translate directly into monthly bills that force real decisions: whether to keep a plan with a familiar doctor, whether to risk going without coverage, whether to delay care and hope costs come down. For a 40-year-old earning $50,000, roughly $167 more each month was not in the budget before January.
The enhanced subsidies were always labeled temporary. The financial pressure they held at bay was not. And until Washington resolves the question of whether to restore, replace, or permanently abandon the expanded credits, that pressure falls squarely on the people least equipped to absorb it: middle-income workers who earn too much for Medicaid but not enough to comfortably pay full freight for private insurance.
