Advance vs. actual
At enrollment you estimate income; the Marketplace pays advance credits to the insurer to reduce your monthly premium. At tax time, actual income determines the credit you're entitled to. The difference flows to your return, either additional refund or amount owed.
What triggers repayment
Income higher than estimated. Repayment caps protect lower-income filers; higher earners repay in full. Above 400% of poverty line, the entire advance credit may need repayment. The usual culprits are a mid-year raise, a spouse returning to work, a large IRA distribution, or self-employment income that came in stronger than the January guess.
The cliff is back for 2026
The enhanced subsidies in place from 2021 through 2025, which capped premiums as a share of income at every income level, expired at the end of 2025. Starting with 2026 coverage, households above 400% of the federal poverty line get no credit at all, and one extra dollar of income can mean repaying thousands. For anyone near the line, year-end income management (retirement contributions, timing a capital gain) is once again genuinely consequential.
The 1095-A is the source document
Form 8962 is built from the Marketplace's Form 1095-A: monthly premiums, benchmark plan costs, and advance credits paid. Returns filed without a required 8962 get held, refunds frozen, and a letter issued, and repeated failure to reconcile disqualifies you from future advance credits. If the 1095-A looks wrong, fix it with the Marketplace before filing, not after.
The self-employed circular calculation
Self-employed people who deduct their health premiums face a genuinely circular computation: the deduction changes AGI, AGI changes the credit, and the credit changes the deductible premium. The IRS provides iterative methods for exactly this. It's the kind of return where software defaults quietly leave money on the table.
Common questions
- What if my Marketplace 1095-A is wrong?
- Request a corrected 1095-A from the Marketplace before filing. Filing with wrong info creates mismatches that delay refunds.
- What happens if I skip Form 8962?
- The IRS holds the return and any refund until the reconciliation is filed, and continued failure to reconcile ends your eligibility for advance credits in future years.
- My income ended up just over four times the poverty line. Do the caps help me?
- No. The repayment caps only apply below 400% of the poverty line. Above it, the full advance credit is repaid, which is why the cliff deserves attention before December 31, not in April.
- I got married mid-year. Does that change the calculation?
- Yes, marriage changes household size and income for the reconciliation, and an alternative calculation for the year of marriage often reduces what would otherwise be a painful repayment.
