If you get help paying health insurance premiums through the Affordable Care Act’s premium tax credit (PTC), an important rule changes for 2026. The change could sharply increase your tax bill if you don’t plan ahead.

Beginning with tax year 2026, taxpayers may need to repay the full amount of any excess advance premium tax credit (APTC). This applies when the APTC received during the year exceeds the amount the taxpayer ultimately qualifies for. Repayment limits will no longer protect many lower- and middle-income taxpayers.

This article explains how reconciliation works and what changed for 2026. It also covers why the change matters and how you can avoid an unexpected tax liability.

Quick Background: How APTC and Reconciliation Work

• The premium tax credit is a refundable credit that helps eligible taxpayers pay Marketplace health insurance premiums. You can claim the credit when you file your return. Alternatively, you can have the Marketplace pay it directly to your insurer to lower your monthly premiums. These payments are called the advance premium tax credit, or APTC. Most taxpayers choose this method.
• At tax time, you must reconcile the APTC you received with the actual credit you qualify for. Your final household income and family size determine the amount of your credit. You complete the reconciliation on Form 8962 and attach it to your Form 1040.
• If your APTC exceeds the PTC you qualify for, you must repay the excess as additional tax. Historically, repayment caps limited how much many taxpayers with household incomes under 400% of the federal poverty line (FPL) had to repay. For tax years 2021 through 2025, COVID relief provisions also expanded PTC eligibility beyond the traditional 400% FPL threshold.
• What Changed for 2026: Before 2026, taxpayers within certain federal poverty line thresholds benefited from statutory repayment caps. These caps limited how much excess APTC they had to repay. Beginning with tax year 2026, taxpayers must repay the entire excess APTC. The previous repayment caps no longer apply. As a result, taxpayers who underestimate their income could face a much larger repayment.

Why This Change Matters

• Bigger Surprise Tax Bills: Under prior law, repayment caps could limit the amount many lower-income taxpayers had to repay. Under the 2026 rule, taxpayers may have to repay the full difference between the APTC received and the PTC allowed. For families receiving substantial APTC, that difference could total several thousand dollars.
• Greater Importance of Accurate Income Estimates: Overestimating your income could reduce your APTC and the immediate assistance you receive. Underestimating your income creates the opposite problem. You could receive too much APTC during the year and face full repayment later. Without a repayment cap, underestimating your income carries a greater financial risk.
• Possible Underpayment Penalty Exposure: A large APTC repayment can also increase your risk of underpayment penalties. This can happen if you did not have enough tax withheld or make sufficient estimated tax payments.
• Filing and Documentation Still Required: Did you or someone in your tax family enroll in Marketplace coverage and receive APTC? If so, you must file a tax return and attach Form 8962 to reconcile your APTC with the credit you qualify for.

An Illustrative Example Scenario — Prior Law (Pre-2026) vs. 2026 Rule

Maria and Luis file a joint return for 2025. During the year, the Marketplace pays $4,000 of APTC to their insurer. That amount reflects the income projection they provided when enrolling.

At year-end, their actual household income is higher than projected. Based on their actual income, they qualify for only $1,500 of PTC.

Their excess APTC equals $4,000 − $1,500 = $2,500.

Under the pre-2026 rules, Maria and Luis might qualify for a repayment limit based on their income and filing status. For example, the limit could cap their repayment at $1,950 in some 2025 scenarios. In that case, they would not have to repay the full $2,500 excess.

The outcome changes under the 2026 rule. Assuming the same facts applied in 2026, Maria and Luis would have to repay the entire $2,500 excess. The previous repayment cap would no longer protect them from the full amount.

Practical Steps to Reduce the Risk of a Large 2026 Repayment

1. Update Marketplace income estimates promptly and throughout the year

   Keeping your Marketplace income estimate accurate is one of the simplest ways to reduce your risk. Report significant changes in income, household size, or other circumstances promptly. The Marketplace can then adjust your APTC from month to month. An accurate income projection reduces your chances of receiving excess APTC.

2. Err on the side of lower APTC if you’re unsure

   Your income may vary if you receive bonuses, commissions, self-employment income, or income from other unpredictable sources. In that case, consider claiming more of the credit on your tax return instead of taking a large APTC. You will receive less premium assistance each month, but you can reduce the risk of a large repayment later.

3. Increase withholding or make estimated tax payments

   If you expect a substantial reconciliation amount, consider increasing the income tax withheld from your paychecks. You can also make quarterly estimated tax payments during the year. Either approach can help cover a potential repayment and reduce the risk of underpayment penalties.

4. Monitor life events and report changes

   Changes in your household or health coverage can affect your PTC eligibility. These changes may include marriage, divorce, births, deaths, household changes, or eligibility for other health coverage. Report them to the Marketplace as soon as they occur.

5. Keep careful records and check Form 1095-A

   Each year, the Marketplace issues Form 1095-A. The form shows your months of coverage and the APTC you received. Use this information to prepare Form 8962 and complete your reconciliation accurately. If you find an error, contact the Marketplace and request a correction before filing.

6. Consult a tax professional if you have complex or changeable income

   Some taxpayers face a greater risk of receiving too much APTC because their income can change significantly. This includes self-employed taxpayers, people with investment income, and those with irregular wages. A tax professional can help you estimate your APTC and manage withholding or estimated payments.

If You Face an Unexpected Repayment

• Don’t Ignore It: You must include excess APTC as additional tax on your return. If you cannot pay the balance in full, contact the IRS to discuss available payment arrangements.
• Consider Payment Options: The IRS offers installment agreements and other options for taxpayers who cannot pay their balance in full. In some circumstances, taxpayers may also request additional time to pay.
• Check Possible Relief: Incorrect information from the Marketplace may have contributed to your repayment issue. For example, the Marketplace may have issued an incorrect Form 1095-A. Contact the Marketplace promptly to request a correction. You may also need to determine whether you should amend your tax return.

Common Questions

Question: What if my income increased unexpectedly late in the year?

Answer: Report the change to your Marketplace as soon as possible. If you already received APTC for several months, you will likely need to reconcile those payments. Beginning in 2026, you may have to repay the full amount of any excess APTC. Consider increasing your withholding or making estimated tax payments to reduce your potential tax balance.

Question: If I repay excess APTC, can I get relief?

Answer: The IRS treats excess APTC repayment as additional tax on your return. Relief is limited and generally requires circumstances such as a Marketplace error or other qualifying factors. If you believe you qualify for relief, consult this office promptly.

To Protect Yourself From a Surprise Tax Bill

• Keep your Marketplace income estimates current.
• Report life and income changes promptly to the Marketplace.
• Consider reducing APTC if your income is uncertain. You can claim more of the credit when you file your tax return.
• Increase withholding or make estimated payments if you expect to owe money.

The 2026 change places more responsibility on taxpayers to actively manage their Marketplace enrollment and tax planning. If you rely on APTC, take steps now to reduce your risk of an unexpected repayment. If you have questions about your specific situation, contact this office for assistance.
