2026 federal rules: the 400% FPL cliff has returned - no credit above that income level. Find your exact SLCSP benchmark premium at healthcare.gov. 48 contiguous states + DC only - Alaska and Hawaii use higher FPL tables.

The formula

FPL (48 states + DC) = $15,650 + $5,500 per additional household member Your % of FPL = (MAGI / FPL for your household size) x 100 2026 Applicable Percentage Table (IRS Rev. Proc. 2025-25): Under 133% FPL: 2.10% - 133-150%: 3.14% to 4.19% - 150-200%: 4.19% to 6.60% 200-250%: 6.60% to 8.44% - 250-300%: 8.44% to 9.96% - 300-400%: 9.96% flat Above 400%: no credit (cliff) Expected contribution = MAGI x Applicable % Premium Tax Credit = Benchmark Silver plan premium - Expected contribution

Example

Single filer, MAGI $38,342 (245% of FPL), benchmark Silver plan $8,000/year: applicable percentage of about 8.26%, expected contribution of $3,165.56/year - a premium tax credit of roughly $403/month.

Step-by-step guide

Find your household MAGI - your estimated total income for the year, plus certain add-backs (most filers' MAGI equals their AGI).
Enter your household size - everyone claimed on your tax return, not just those needing coverage.
Find your area's benchmark Silver plan (SLCSP) cost at healthcare.gov and enter the annual premium, then read your estimated monthly credit.

Why 2026 looks meaningfully different from recent years

From 2021 through 2025, temporarily enhanced subsidies eliminated the 400% FPL income cap entirely and capped everyone's contribution at 8.5% of income, regardless of how high their earnings were. Those enhancements expired at the end of 2025, and 2026 reverts to the original ACA structure: a hard income cliff at 400% of FPL (above which the credit is exactly zero, not just smaller), and a steeper contribution schedule that tops out at 9.96% instead of 8.5%. For many households, especially those with income between 200-400% FPL, this means a meaningfully higher expected contribution than in recent years - worth budgeting for if your income has stayed roughly the same.

Common mistakes

Assuming a small overage above 400% FPL still gets a partial credit - it's a genuine cliff, not a gradual phase-out. One dollar over the line means zero credit, not a slightly smaller one.

Using the premium of the plan you actually want instead of the benchmark Silver (SLCSP) plan - your credit amount is fixed based on the SLCSP, even if you ultimately choose a cheaper Bronze plan or a pricier Gold plan.

Frequently asked questions

What happens if I receive advance credits but my actual income ends up higher?

You may need to repay some or all of the excess credit when you file your taxes on Form 8962, though repayment is capped for most households below 400% FPL - crossing above 400% FPL can require repaying the full excess amount.

Can I choose to take the credit at tax time instead of monthly?

Yes - most people take it in advance as a monthly premium reduction, but you can also pay full price during the year and claim the entire credit when you file your tax return instead.

Does this apply if I have access to employer health coverage?

Generally no - if you have access to affordable, minimum-value employer coverage, you typically aren't eligible for marketplace subsidies, even if you decline the employer plan and buy through the marketplace instead.
