What Is Premium Tax Credit Repayment?
When you enroll in an ACA marketplace plan, you estimate your income for the year to determine your eligibility for premium tax credits (subsidies). If you choose to receive Advance Premium Tax Credits (APTC), the government pays part of your premium directly to your insurer each month.
At tax time, you must reconcile (compare) the advance credits you received with the amount you actually qualify for based on your final income. If you received more in advance than you should have, you must repay the difference—subject to repayment caps.
Tax Credit Reconciliation Process
Common Scenarios Requiring Repayment
Income Increased
You got a raise, bonus, or new job that paid more than expected. Your actual income was higher than your January estimate, making you eligible for less subsidy.
Household Size Decreased
A dependent moved out, got married, or aged out. Smaller household size means higher income relative to the Federal Poverty Level, reducing subsidy eligibility.
Marriage
You got married and filed jointly. Combined household income may push you over subsidy thresholds, especially if both spouses have income.
Income Estimation Error
You underestimated your income when applying. Even without life changes, if your estimate was low, you received too much APTC and must repay.
Repayment Caps: Maximum You'll Owe
The good news: If your final income is still under 400% of the Federal Poverty Level, there's a cap on how much you have to repay. The cap amount depends on your household income as a percentage of the FPL.
Protection for Lower Incomes
Repayment caps protect you from owing thousands of dollars if your income increased but stayed under 400% FPL.
2024 Repayment Cap Table
| Income as % of FPL | Single Filers | All Other Filing Statuses |
|---|---|---|
| Less than 200% | $350 | $700 |
| 200% - 300% | $900 | $1,800 |
| 300% - 400% | $1,500 | $3,000 |
| 400% and above | NO CAP - Must repay full amount | |
Critical Threshold: 400% FPL
If your income exceeds 400% of the Federal Poverty Level, there is NO REPAYMENT CAP. You must repay ALL advance premium tax credits received during the year, which could be thousands of dollars.
IRS Form 8962: Premium Tax Credit Reconciliation
You reconcile your premium tax credits on IRS Form 8962, which you file with your federal tax return. This form calculates:
- The premium tax credit you actually qualify for based on your final income
- The advance premium tax credits you received during the year
- Whether you owe repayment or deserve an additional refund
Form 1095-A Is Required
Your marketplace plan will send you Form 1095-A (Health Insurance Marketplace Statement) after the end of the year. You MUST have this form to complete Form 8962.
Form 1095-A shows your monthly premiums, the amount of APTC paid on your behalf, and the second-lowest cost Silver plan (SLCSP) premium used to calculate your subsidy.
Repayment Examples
✅ Example 1: Income Increase with Cap Protection
Situation: Sarah (single) estimated $30,000 income, received $4,000 in APTC
Reality: She earned $38,000 (still under 400% FPL)
Result: Based on $38,000, she only qualified for $2,800 in tax credits
Overpayment: $4,000 - $2,800 = $1,200
Repayment: Capped at $900 (her income is 200-300% FPL, single filer)
Sarah owes $900, not $1,200, thanks to the repayment cap.
❌ Example 2: Income Exceeds 400% FPL
Situation: John (single) estimated $48,000 income, received $3,600 in APTC
Reality: He earned $62,000 (over 400% FPL = ~$60,000 for single in 2024)
Result: He doesn't qualify for ANY premium tax credit at $62,000
Overpayment: $3,600
Repayment: NO CAP applies - must repay full $3,600
John owes the entire $3,600 because he exceeded 400% FPL.
💰 Example 3: Additional Refund
Situation: Maria estimated $45,000 income, took $2,000 in APTC
Reality: She earned $40,000 (lower than estimated)
Result: Based on $40,000, she qualified for $3,200 in tax credits
Additional Credit: $3,200 - $2,000 = $1,200
Maria gets an extra $1,200 tax refund!
How to Avoid Surprise Repayment
Report Income Changes Immediately
The best way to avoid owing money at tax time is to report income changes to the marketplace as they happen.
Other Strategies
- Take Lower APTC: Choose to receive less than your full subsidy to create a buffer
- Monitor Income: Track your year-to-date income regularly
- Be Conservative: Estimate income on the higher side when uncertain
- Review Quarterly: Check if your situation changed every few months
- Save for Taxes: Set aside money in case you owe repayment
Special Situations
Married Filing Separately
If you're married but file separately (except in cases of domestic abuse or spousal abandonment), you're generally not eligible for premium tax credits. If you received APTC, you must repay the full amount—no cap applies.
Cannot Be Claimed as a Dependent
If you can be claimed as a dependent on someone else's tax return, you're not eligible for premium tax credits. If you mistakenly received APTC, you must repay it all.
Partial Year Coverage
If you had marketplace coverage for only part of the year, you only reconcile tax credits for the months you were enrolled.
