Obamacare Marriage Penalty Chart: 2026 Limits and the 400% Cliff

The Obamacare marriage penalty is the loss of premium tax credits that hits when two people combine incomes on a joint tax return: the federal poverty level for a two-person household ($21,640 in 2026) is only about 68% of what two single people would be measured against separately ($15,960 each, or $31,920 combined), so the same total income counts as a higher share of the poverty line once you’re married.¹ That higher percentage means a larger expected contribution toward your benchmark plan and a smaller subsidy, and in some cases no subsidy at all. The effect is sharper in 2026 than in the past five years, because the temporary enhanced credits that softened it from 2021 through 2025 expired on January 1, 2026.²

Why Combining Incomes Costs You

The premium tax credit runs on two inputs: your household’s Modified Adjusted Gross Income and the federal poverty level for your household size.³ The IRS expresses income as a percentage of the poverty line, then applies a sliding scale to decide what share of income you’re expected to pay toward the second-lowest-cost silver plan. Anything above that expected contribution is covered by the subsidy.

Marriage moves both inputs the wrong way at once. Household income roughly doubles when two earners combine. The poverty baseline does not; it goes up by about 36%, not 100%. Divide a bigger income by a smaller-than-expected baseline and the poverty-level percentage jumps, which pushes you into a higher contribution tier and can push you past the cutoff entirely.

2026 Income Limits for Married Couples

Subsidy eligibility in 2026 requires household income between 100% and 400% of the federal poverty level.⁴ For the 48 contiguous states, the 2026 guidelines set the thresholds like this:¹

Single, 100% FPL: $15,960
Single, 400% FPL: $63,840
Two-person, 100% FPL: $21,640
Two-person, 400% FPL: $86,560

Two single filers can each earn up to $63,840 and still qualify, for a combined ceiling of $127,680. A married couple’s ceiling is $86,560. Any combined income between $86,561 and $127,680 falls in a zone where both spouses would qualify individually but the couple qualifies for nothing.

2026 Contribution Percentages

Once you’re eligible, this table sets your expected contribution to the benchmark plan as a share of household income:⁵

Below 133% FPL: 2.10%
133% to 150% FPL: 3.14% rising to 4.19%
150% to 200% FPL: 4.19% rising to 6.60%
200% to 250% FPL: 6.60% rising to 8.44%
250% to 300% FPL: 8.44% rising to 9.96%
300% to 400% FPL: 9.96% flat
Above 400% FPL: no credit

These percentages are higher across every tier than they were from 2021 through 2025, when temporary legislation lowered contributions and removed the 400% cutoff. That expansion was not renewed.²

What the Penalty Looks Like in Dollars

Mid-Range Incomes

Two single people each earn $35,000. Individually, each is at about 219% FPL ($35,000 ÷ $15,960), landing in the 200%–250% bracket at roughly 7.3% of income. Each is expected to contribute about $2,555 per year to the benchmark plan.

Married, their combined $70,000 sits at about 323% of the two-person FPL ($70,000 ÷ $21,640), which puts them in the flat 9.96% band. Their expected contribution rises to $6,972 per year. Against their combined single contributions of $5,110, the marriage penalty here is about $1,860 a year in lost subsidy.

At the Edge of the Cliff

Two single people each earn $43,000. As individuals, each sits comfortably at about 269% FPL. Combined, their $86,000 lands at 397% of the two-person FPL, just under the 400% line. They keep their credits, but the margin is thin. A $300 raise, a small bonus, or an unexpected capital gain crosses $86,560 and wipes out the credit for the year.¹ As singles, neither would hit 400% FPL until earning $63,840.

The 400% Cliff Is Back, and the Repayment Cap Is Gone

The steepest version of the penalty is not a gradual reduction. Once combined income crosses 400% of the two-person FPL ($86,560), the couple loses every dollar of credit for the year. There is no phase-out.⁴ During 2021–2025, people above 400% FPL still received credits that capped their contribution at 8.5% of income. That safety net is gone in 2026.

A second change makes 2026 harsher still. Before this year, taxpayers below 400% FPL had a cap on how much excess advance credit the IRS could recover at tax time, ranging from $350 to $3,200 depending on income and filing status. Starting with tax year 2026, there is no cap. Whatever advance credits exceeded your actual credit must be repaid in full.⁶ A couple who received advance credits based on pre-marriage estimates, then finds combined income pushed them past $86,560, can owe back the entire year’s advance credits, an amount that can easily top $10,000.

You Have to File Jointly

The statute is explicit: married taxpayers must file a joint return to claim the premium tax credit.² Filing married filing separately disqualifies you outright, with two narrow exceptions.⁴ So the income-combining problem is not something you can plan your way around by choosing a different filing status. If you received advance credits during the year and then file separately, you owe back every dollar of them.

Domestic Abuse or Spousal Abandonment

A victim of domestic abuse or spousal abandonment can file separately and still claim the credit, provided you’re living apart from your spouse when you file and you check the certification box on Form 8962.⁷ This exception is limited to three consecutive tax years. If you’ve used it in each of the three preceding years, it’s not available in the current year.

Head of Household

A married person “considered unmarried” for tax purposes can file as head of household. That requires all three of the following:⁸

You and your spouse lived in separate homes for the entire last six months of the tax year.
You paid more than half the cost of keeping up your home.
Your home was the main residence of a dependent child, stepchild, or foster child for more than half the year.

Head of household filing measures your income against the single-person poverty line, which removes the marriage penalty from your own coverage.

If You Married During the Year

Two things matter if the wedding happened mid-year: what to do at tax time, and what to do now.

At tax time, Form 8962 offers an optional alternative calculation for the year of marriage. It lets you treat your pre-marriage months using your individual income rather than dragging your combined married income back across the whole year. That won’t erase the penalty on months you were married, but it can meaningfully cut how much advance credit you have to repay. Eligibility runs through Table 4 and Worksheet 3 of the Form 8962 instructions, with the detailed worksheets in Publication 974.⁹⁷ It’s easy to miss, so flag it for your preparer.

Right now, tell the Marketplace. Marriage is a change you’re expected to report so your advance credit amount can be recalculated on your new combined household income.¹⁰ Letting advance credits keep flowing at your old single-person amount is where couples get hurt most, because with the 2026 repayment cap gone, the full overpayment comes back at tax time. If the recalculated income means you no longer qualify, better to know in July than in April.
