Written and reviewed by Dick Tracy, licensed health insurance broker (NPN 20414610) · Published August 8, 2026 · Updated September 4, 2026 (dollar-estimate calculator link)
For 2026 coverage the marketplace subsidy cliff is back: earn even one dollar over 400% of the federal poverty level for your household size and your subsidy is zero. Not smaller. Zero. This free calculator tells you in 60 seconds which side of the line you are on, how close you are, and what to do about it. Under the line and want the credit in dollars? That is the 2026 ACA subsidy calculator. No email required, no signup, nothing to download. I educate, you decide.
Self-employed? Use this number, not what you pay yourself
- Schedule C net profit (what came in minus your business deductions)
- minus half of your self-employment tax
- minus SEP-IRA or Solo 401(k) contributions
- minus the self-employed health insurance deduction
- plus any other household income: a spouse's W-2, interest, capital gains, the untaxed part of Social Security
Before you count on that subsidy: 8 knockout questions
Income is only half the test. Check any that apply to anyone in your tax household for 2026.
Estimates only, based on 400% of the 2025 federal poverty guidelines for the lower 48 states and DC (Alaska and Hawaii use higher figures). "Income" means modified adjusted gross income (MAGI) for 2026, which is not always the number on your pay stub. This is education, not tax or enrollment advice. Bring me the number and we'll run it together.
The number lines for 2026, household by household
The cliff sits at 400% of the federal poverty level. For 2026 coverage that means roughly $62,600 for a single person, $84,600 for a couple, $106,600 for a household of three, and $128,600 for a family of four, adding about $22,000 for each additional person. What counts is your modified adjusted gross income for 2026, the year you have the coverage, not last year's tax return. A family paying $675 a month with the subsidy can be renewed at $2,100 a month without it. Same plan, same doctors, same deductible. That is over $17,000 a year in new cost for crossing a line by a dollar. The math doesn't math, and nobody at the marketplace is going to call and warn you.
What to do with your result
If you are under the line, make sure the income estimate on your application is accurate, because the IRS reconciles subsidies at tax time and a wrong number lands on you, not the marketplace. If you are close to the line, know your cushion and get a plan B priced before a good year surprises you. And if you are over the line, do not just accept the sticker-price renewal. New York folks: healthy people and families can merge into pre-established ERISA group plans and get group rates, because ERISA is federal law and the state cannot block it. Everywhere else, private coverage priced on you often costs meaningfully less than an unsubsidized marketplace plan. I compare all of it side by side and show you real numbers, so talk to me before you assume anything.
Common questions about the 2026 subsidy cliff
How do I know if I am over the cliff?
Compare your household's modified adjusted gross income for 2026 against 400% of the federal poverty level for your household size: roughly $62,600 for one person, $84,600 for a couple, $106,600 for three, $128,600 for four, plus about $22,000 per additional person. At or under the line, help is still available. Over it, even by a dollar, the subsidy is zero. The calculator above does this for you.
What counts as income?
Modified adjusted gross income (MAGI) for the coverage year: wages, self-employment profit, most investment income, Social Security. The trap: a claimed dependent who earns enough to be required to file a return can add their income to the household number. A kid with a real job can silently push the whole family over.
What happens if I go one dollar over?
You lose the entire subsidy. There is no taper above the line for 2026. A family paying $675 a month with help can be renewed at $2,100 for the same plan without it. And if you underestimated your income to get the subsidy, you can owe money back at tax time.
Can I get my income under the line?
Sometimes. Pre-tax retirement contributions and self-employed deductions both lower MAGI. Business owners and 1099 earners often have real room. Run the actual numbers with your tax professional before counting on it.
What if I am over the cliff and get nothing?
Then the marketplace has no built-in price advantage for you anymore, and there are two doors outside it that are not income-tested. In New York, healthy people and families can merge into pre-established ERISA group plans at group rates, because ERISA is federal law. In most other states, private plans priced on you instead of community-rated can cost meaningfully less than an unsubsidized marketplace plan. Compare them side by side before you renew anything. I educate, you decide.
Can I get the premium tax credit if I am married filing separately?
No, with one narrow exception. Married couples must file a joint return to claim the credit. File separately and the credit is zero, and any advance subsidy the marketplace already paid your insurer during the year has to be repaid in full. The only exception is a spouse who is a victim of domestic abuse or spousal abandonment, living apart, who checks the box on Form 8962, and it can only be used for three consecutive years.
Can I turn down my employer's health insurance and get a marketplace subsidy instead?
Usually not. If you or your spouse are offered job coverage the IRS calls affordable and minimum value, nobody who could enroll in it gets the credit, even if you never signed up. For 2026, affordable means the employee-only premium for the cheapest plan is 9.96% of household income or less. Since 2023 a spouse and kids are tested separately on the cost of family coverage, so they can sometimes qualify when the employee cannot. And if you actually enroll in the job plan, you are ineligible that month no matter what it costs.
What income does a self-employed person use for the subsidy?
Net profit, not what you pay yourself. The marketplace uses modified adjusted gross income, which starts at line 11 of Form 1040. For a sole proprietor that means Schedule C net profit, less half of self-employment tax, less SEP or Solo 401(k) contributions, less the self-employed health insurance deduction. Not your owner's draw, not your gross receipts, not what hit your checking account. Entering the draw is the single most common self-employed subsidy mistake, and for 2026 it lands as a full repayment at tax time.
Do I have to pay back the subsidy if my income goes up in 2026?
Yes, and for 2026 coverage there is no longer a cap on how much. From 2014 through 2025 the IRS limited the clawback for households under 400% of the poverty level to between $375 and $3,250. Public Law 119-21 removed every repayment cap starting with the 2026 plan year. Whatever advance subsidy you were not entitled to based on your actual income, you repay all of it on your 2026 return. Report income changes to the marketplace the month they happen, not at renewal.
Can I keep my marketplace subsidy after I turn 65?
No. Once you are eligible for premium-free Medicare Part A, the credit ends for you, whether or not you enrolled in Medicare. The marketplace does not stop the subsidy for you. If it keeps paying your insurer after your Medicare eligibility starts, you repay those months at tax time. Contact the marketplace the month before you turn 65 and line up Medicare and, if you want one, a supplement. The full list of who cannot claim the credit is on my 12 knockouts page.
