For 2027 coverage, the premium tax credit caps what you pay for the benchmark silver plan at 2.15% to 10.22% of income, but only up to 400% of the poverty line: $63,840 for one person, $132,000 for a family of four. The enhanced credits of 2021β2025 have expired.

Premiums: 2026 HealthCare.gov premiums until CMS publishes 2027 rates (CMS data as of 2026-08-04). For households that get a subsidy, a higher 2027 benchmark premium raises the subsidy by the same amount, so the net cost of the benchmark plan depends only on income.

How the 2027 subsidy is calculated
Find your income as a share of the poverty line. Divide expected 2027 household MAGI by the 2026 poverty guideline for your household size ($15,960 for one person, plus $5,680 per additional person).
Look up your expected contribution. The IRS table below sets the share of income you are expected to pay for the benchmark plan.
Subtract it from the benchmark premium. The benchmark is the second-lowest-cost silver plan in your county, priced for the ages of everyone enrolling. The difference is your monthly credit, which you can apply to any metal level.
Example: a 40-year-old in Miami-Dade County earning $40,000 (251% of the poverty line) is expected to pay 8.68% of income, or $289 a month. The benchmark plan costs $684, so the credit is $395 a month.

The 400% cliff is back
The cliff hurts most for older enrollees, because premiums for a 60-year-old are 2.7 times those of a 21-year-old. A married couple, both 60, in Miami-Dade County earning $85,560 pays $729 a month for the benchmark plan. At $87,560, $2,000 more, they pay the full $2,907: $26,136 more a year.
If you are close to the line, pre-tax contributions lower MAGI dollar for dollar. Contributing to a traditional 401(k) or IRA, or to an HSA alongside a bronze HSA-eligible plan, can bring income back under the limit. See the 401(k) and IRA calculator for how much you can put in.
What changed for 2027
Enhanced credits expired. The 2021β2025 rules capped contributions at 8.5% of income with no upper income limit. They ended on December 31, 2025; a House-passed extension has not cleared the Senate.
Contribution percentages rose. The top rate is 10.22% of income for 2027, up from 9.96% for 2026.
No repayment cap. Since 2026 coverage, excess advance credits must be repaid in full at tax time, whatever your income.
Some lawfully present immigrants lost eligibility. Those with income under 100% of the poverty line who are ineligible for Medicaid because of immigration status can no longer get the credit.
2027 subsidy examples: a 40-year-old in Miami-Dade County
A single 40-year-old in Miami-Dade earning $40,000 gets about $395 a month of premium tax credit, which brings the benchmark silver plan down to $289 a month; above $63,840 the credit drops to zero.

The benchmark (second-lowest-cost silver) plan for a 40-year-old costs $684 a month before the credit (2026 HealthCare.gov premiums until CMS publishes 2027 rates). The credit is the benchmark minus the IRS expected contribution at each income.
Frequently asked questions
How is the 2027 ACA subsidy calculated?
The premium tax credit equals the price of the second-lowest-cost silver plan in your area (the benchmark) minus your expected contribution. For 2027, the expected contribution runs from 2.15% to 10.22% of household income, depending on where your income falls relative to the 2026 federal poverty guidelines. If the benchmark costs less than your contribution, the credit is zero.
What is the income limit for ACA subsidies in 2027?
400% of the federal poverty line: $63,840 for one person, $86,560 for two and $132,000 for a family of four in the 48 contiguous states (higher in Alaska and Hawaii). The enhanced credits that removed this limit expired on December 31, 2025, and Congress has not extended them, so a household one dollar over the line gets no subsidy at all.
Do I have to pay back the subsidy if my income is higher than expected?
Yes, in full. Starting with 2026 coverage, the caps that used to limit repayment are gone: any advance credit you received above what your final income allows is added to your tax bill. If your income could end up near $63,840 (single), update your Marketplace application during the year or take less of the credit in advance.
What income counts for the ACA subsidy?
Modified adjusted gross income (MAGI) for everyone in your tax household: your adjusted gross income plus untaxed foreign income, tax-exempt interest and non-taxable Social Security benefits. Pre-tax 401(k), traditional IRA and HSA contributions lower MAGI, which is why they are the main way to get back under the 400% line.
Why does the calculator say I qualify for Medicaid instead?
In the 40 states plus DC that expanded Medicaid, adults with income below 138% of the poverty line generally qualify for Medicaid and cannot get Marketplace subsidies. In the 10 states that did not expand (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin and Wyoming), subsidies start at 100% of the poverty line; below that, most adults fall into the coverage gap, except in Georgia and Wisconsin, which cover adults up to 100% through waivers.
Should I pick a bronze or a silver plan?
If your income is at or below 250% of the poverty line, silver plans come with cost-sharing reductions that cut deductibles and out-of-pocket limits, often making silver the best value even if bronze costs less per month. Above 250%, the subsidy is a fixed dollar amount, so the cheapest bronze plan can drop to very little or nothing, at the cost of a much higher deductible.
Why is my state not in the calculator?
The county premiums come from the CMS QHP Landscape file, which covers the 30 states that use HealthCare.gov. States that run their own exchange, such as California, New York, New Jersey, Pennsylvania and Washington, publish premiums separately; the subsidy formula is the same there, so you can enter their benchmark premium into the formula yourself or use the state's own calculator.
This is an estimate, not an eligibility determination or a quote. Your actual credit is set by the Marketplace and reconciled on your tax return. Apply at HealthCare.gov or your state's exchange.
