2026 ACA Subsidy Overpayments May Be Fully Clawed Back After Income Surprises

For 2026 ACA coverage, premium tax credits are based on estimated income and must be reconciled on tax returns. If a single person’s modified adjusted gross income exceeds 400% of the federal poverty line, they may have to repay all subsidy received, with no repayment cap for 2026. A $5,000 income increase can create a much larger tax bill, though deductible IRA, HSA, or SEP contributions before the filing deadline may lower MAGI.
For 2026 marketplace coverage, advance premium tax credits are initially calculated from the income a person projects at enrollment. The IRS later reconciles that estimate through Form 8962. If a single enrollee’s modified adjusted gross income ends up above 400% of the federal poverty line, the credit can fall to zero, requiring repayment of all advance subsidy received.
The 2025 poverty guideline for one person is $15,650, making the 400% threshold $62,600. In the example, a $5,000 increase to $63,000—just $400 over—erases a $7,423.20 credit. Combined with 12% income tax on the extra $5,000, the total cost reaches $8,023.20. Deductible IRA, HSA, or SEP contributions before the filing deadline may reduce MAGI.
