Enhanced Premium Tax Credit Expiration: 400% Cliff Returns

The enhanced premium tax credit expiration took effect on December 31, 2025, and subsidized marketplace enrollees face an average annual premium increase of about 114%, roughly doubling from $888 to $1,904 per year. Three changes hit at once for 2026 coverage: the 400% federal poverty level income cap returns, the share of income you’re expected to contribute rises across every bracket, and zero-dollar premium plans disappear for low-income households. A fourth change, less visible until tax season, removes the caps on how much you may have to repay if your advance credits turn out to be too high.¹

What Rules Apply Now

The expanded credits that ran from 2021 through 2025 have lapsed. Starting with the 2026 tax year, the premium tax credit reverts to the original framework written into the Internal Revenue Code under the Affordable Care Act.² If you picked a 2026 plan during open enrollment (November 1, 2025 through January 15, 2026), the higher quotes you saw reflect both the reduced subsidy and insurer rate increases of roughly 18% on individual market plans.¹

The 400% Income Cliff Returns

During the enhancement period, there was no upper income limit on eligibility. A household earning $200,000 could still qualify if their benchmark premium exceeded 8.5% of income. That flexibility is gone. For 2026, any household with income above 400% of the federal poverty level is completely ineligible for the premium tax credit.²

Using the 2026 federal poverty guidelines, the 400% threshold works out to $63,840 for a single individual and $132,000 for a family of four in the 48 contiguous states and Washington, D.C.³ Earn a dollar over those figures and you lose the entire credit, not a portion of it. An estimated 725,000 enrollees with incomes between 400% and 500% of the poverty level will lose eligibility altogether.¹

Higher Required Contributions at Every Income Level

The premium tax credit calculates how much you’re expected to pay toward the second-lowest-cost silver plan in your area, then covers the gap between that amount and the actual premium. What changed for 2026 is the expected contribution itself. Under the enhanced rules, everyone was capped at 8.5% of household income and people below 150% of the poverty level paid nothing. The 2026 percentages published by the IRS run meaningfully higher at every bracket.⁴

Below 150% FPL: enhanced rate 0%; 2026 rate 2.10% to 4.19%.
150% to 200% FPL: enhanced rate 0% to 2.0%; 2026 rate 4.19% to 6.60%.
200% to 250% FPL: enhanced rate 2.0% to 4.0%; 2026 rate 6.60% to 8.44%.
250% to 300% FPL: enhanced rate 4.0% to 6.0%; 2026 rate 8.44% to 9.96%.
300% to 400% FPL: enhanced rate 6.0% to 8.5%; 2026 rate a flat 9.96%.

Take your household income, multiply by the applicable percentage, and divide by twelve. That’s your expected monthly contribution toward the benchmark silver plan. Because that expected contribution rose, the credit covering the rest of the premium shrinks, and your out-of-pocket cost goes up. For someone at 250% of the poverty level, the required contribution more than doubles from about 4% to roughly 8.4% of income.²

The credit is calculated against the benchmark silver plan, but you can apply it to any metal tier. If silver has become unaffordable, a bronze plan with lower premiums and higher deductibles may keep your monthly cost manageable. You lose access to cost-sharing reductions by leaving silver, but you keep the tax credit.⁵

Zero-Premium Plans End

From 2021 through 2025, anyone earning between 100% and 150% of the federal poverty level paid nothing for a benchmark silver plan. The enhanced rules set their contribution percentage at zero. Millions of enrollees carried comprehensive coverage with no monthly bill. That arrangement is over.

For 2026, people in this income range face a required contribution starting at 2.10% of income. In dollar terms, a single individual at 150% of the poverty level would pay roughly $82 per month for the benchmark silver plan; someone just above the poverty line would pay around $28 per month.⁴ For households that budgeted zero, that’s a new fixed expense.

Cost-Sharing Reductions Did Not Change

Not every marketplace subsidy expired. Cost-sharing reductions, which lower your deductibles, copays, and coinsurance when you enroll in a silver plan, remain available in 2026 for households earning up to 250% of the federal poverty level. They are separate from the premium tax credit and were never part of the temporary enhancement.

Up to 150% FPL: silver plan covers about 94% of costs, with an out-of-pocket maximum around $3,500 for an individual.
151% to 200% FPL: coverage rises to about 87% of costs, with a similar $3,500 out-of-pocket cap.
201% to 250% FPL: coverage drops to about 73%, with an out-of-pocket maximum near $8,450.

These reductions apply only to silver-tier plans. If higher premiums tempt you toward a cheaper bronze plan, you lose the reductions entirely. For people in the 100% to 250% FPL range, staying on silver often still makes financial sense once you account for the lower out-of-pocket costs when you actually use care.⁵

Repayment Caps Are Gone

This is the change most likely to catch people off guard. Through 2025, the IRS limited how much you had to repay if your advance premium tax credits turned out to be too generous. A single filer earning under 200% of the poverty level owed back no more than $375 regardless of the size of the overpayment. Those caps no longer exist for 2026.⁶

Starting with the 2026 tax year, you must repay the full difference between your advance credits and the credit you actually qualified for. If you estimated your income at $60,000 and received $4,000 in advance credits, but your actual income came in at $70,000 and qualified you for nothing, you owe back the entire $4,000. That amount is added to your tax liability, reducing your refund or increasing your balance due.⁶

The cliff makes this worse. If you took advance credits based on a projected income below 400% of the poverty level, but your actual income crossed that line, you owe back every dollar of advance credits you received. There is no partial repayment or pro-rated reduction once you’re above the threshold.⁷

Every enrollee who receives advance credits must file Form 8962 with their federal return to reconcile the payments. Skip it, and the IRS will block you from receiving advance credits or cost-sharing reductions the following year.⁸

Update the Marketplace When Anything Changes

The marketplace sets your advance credit based on projected income and household size at enrollment. If either changes during the year, update your application as soon as you can. Waiting until tax time almost always makes the bill worse.⁹

Reportable changes include any increase or decrease in expected income, and gaining or losing a household member through birth, adoption, marriage, divorce, or a dependent aging off your plan at 26. Report it as well if anyone in the household gets an offer of employer coverage or qualifies for Medicaid, Medicare, or CHIP.¹⁰

When you report a change, the marketplace recalculates your credit in real time. If income dropped, advance payments rise and your monthly premium falls. If income rose, advance payments decrease before an overpayment builds up. With no repayment caps to soften the tax-time landing, keeping the application current is the single most effective way to avoid a surprise bill.

If You’re Near the 400% Cliff

The premium tax credit uses modified adjusted gross income, which means certain above-the-line deductions directly reduce the number that determines your eligibility. If your income hovers near 400% of the poverty level, a few ordinary planning moves can keep you on the credit-eligible side.

Traditional IRA contributions. The 2026 limit is $7,500, or $8,600 if you’re over 50. A deductible contribution lowers MAGI dollar for dollar.
HSA contributions. If you’re enrolled in a high-deductible health plan, you can contribute up to $4,400 as an individual or $8,750 for family coverage in 2026. These reduce MAGI as well.
Self-employment deductions. Every legitimate business expense on Schedule C lowers MAGI. The self-employed health insurance deduction reduces MAGI by the full premium if business income covers it.
Capital loss harvesting. Up to $3,000 in net capital losses can offset ordinary income each year.

A household at 401% of the poverty level loses the entire credit, which can mean several thousand dollars in additional annual premium cost compared to a household at 399%. Running a mid-year income projection in October or November, while there’s still time to make an IRA or HSA contribution, is worth the effort. If income consistently lands well above 400% and no deduction bridges the gap, the practical move is shopping for the lowest-premium plan that meets your needs and budgeting for the full unsubsidized cost. Employer-sponsored coverage, a spouse’s plan, or a professional association group plan may offer better rates than the individual marketplace at that income level.
