The ACA Subsidy Cliff Is Back in 2026: What It Means for You

From 2021 through 2025, temporary rules from the American Rescue Plan and Inflation Reduction Act made Marketplace subsidies larger and removed the income cap. Those rules expired on December 31, 2025. For 2026 coverage, the original Affordable Care Act formula is back — including the “cliff” at 400% of the federal poverty line.

What changed for 2026

• The share of income you’re expected to pay for the benchmark silver plan is now 2.10% to 9.96%, up from 0% to 8.5%.
• Households above 400% of the poverty line get no premium tax credit, however expensive coverage is.
• 2026 coverage uses the 2025 poverty guidelines: $15,650 for one person plus $5,500 for each additional person.

How steep is the cliff?

Take a couple in their early 60s whose benchmark silver plan costs $2,000 a month at full price. The 400% line for two people is $84,600.

• At $83,600 of income, their credit is about $1,306 a month ($15,673 a year).
• At $85,600 — $2,000 more — the credit is $0.

Earning an extra $2,000 costs them roughly $15,673 in lost subsidy. Older enrollees feel this most, because full-price premiums for people in their 60s can be three times those of a 21-year-old.

How to stay under the line

The test uses modified adjusted gross income (MAGI) for the whole year. Ways to lower it:

• Contribute to a traditional 401(k), 403(b), SEP-IRA or Solo 401(k).
• Make deductible Traditional IRA and HSA contributions.
• If you’re self-employed, deduct business expenses and self-employed health insurance premiums.
• Time capital gains, Roth conversions and IRA withdrawals carefully.

Because credits are reconciled on your tax return, an unexpected bonus late in the year can mean repaying the entire advance credit. Re-estimate your income mid-year and update your Marketplace application if it changes.
