Form 1095-A reduces your refund if you got more tax credits than you were supposed to

Form 1095-A reports the health insurance subsidies you received during the year through the Affordable Care Act marketplace. If you got more in subsidies than your actual income may have access to you for, the IRS claws back the overpayment from your refund. This is called reconciliation, and it happens automatically when you file.

The amount that lowers your refund depends on two things: how much subsidy you actually got, and how much you should have gotten based on your final income. If your income was lower than you estimated when you signed up for insurance, you got too little subsidy and the IRS owes you money—your refund goes up. If your income was higher, you got too much subsidy and your refund goes down.

You cannot avoid this. The 1095-A is sent to both you and the IRS, and your tax software will ask for the information when you file. If you do not report it, the IRS will catch the missing form and delay your refund while they investigate.

Key Takeaways

  • Form 1095-A shows how much health insurance subsidy you received, and reconciliation adjusts your refund to match what you actually earned.
  • If your income turned out higher than you estimated, you owe back some or all of the subsidy, which reduces your refund dollar-for-dollar.
  • If your income turned out lower, you get a refund boost because you should have received more subsidy than you did.
  • You must report the 1095-A when you file; tax software will prompt you for the information from the form.

When 1095-A lowers your refund

Your refund shrinks when your actual income for the year was higher than the income you reported when you enrolled in marketplace insurance. The IRS subsidizes your premiums based on a forecast of your income. If you earn more than that forecast, you were overpaid in subsidies and must return the difference.

The reconciliation is automatic. Your tax software compares the subsidy amount shown on your 1095-A to the subsidy you should have gotten based on your actual income and tax filing status. If there is a gap, that gap comes out of your refund. If your refund is smaller than the amount you owe back, you will owe the IRS money when you file.

Example: You estimated $45,000 income when you signed up and received $300 per month in subsidies ($3,600 for the year). Your actual income was $55,000. At $55,000, you should have received $200 per month ($2,400 for the year). You owe back $1,200, which reduces your refund by that amount.

When 1095-A increases your refund

Your refund grows when your actual income was lower than you estimated during enrollment. You received less subsidy than you should have, so the IRS owes you the difference. This boost appears as an additional refund amount when you file.

This happens most often to people whose income dropped mid-year due to job loss, reduced hours, or self-employment income that came in lower than expected. If you reported the income change to the marketplace during the year, your monthly subsidy may have already been adjusted, so the reconciliation at tax time will be smaller or zero.

If you did not report the change, the full difference between what you got and what you should have gotten will show up as a refund increase. This is one reason to update your marketplace account if your income changes—it prevents a large reconciliation surprise at tax time.

How to find the reconciliation amount on your 1095-A

Your 1095-A arrives by mail or email in January or early February. Box 1 shows the monthly subsidy amount you received. Box 2 shows the total subsidy for the year. The form does not calculate what you should have received—that is what your tax software does when you file.

When you enter your 1095-A information into tax software, the program will show you the reconciliation calculation. It compares your actual income to the subsidy you got and tells you the amount that will adjust your refund. You can see this before you file, so there are no surprises when your return is processed.

If you received coverage from more than one marketplace plan during the year, you will get more than one 1095-A. You must report all of them. Tax software will add up the total subsidy from all forms and reconcile against your total income.

What happens if you do not report the 1095-A

The IRS receives a copy of every 1095-A issued. If your tax return does not include the form, the IRS will match it to your Social Security number and flag your return. This does not automatically reject it, but it will delay processing while the IRS investigates the discrepancy.

You may receive a notice asking you to file an amended return that includes the 1095-A. If you ignore the notice, the IRS will calculate the reconciliation themselves and send you a bill for any subsidy overpayment, plus interest and penalties. It is faster and cheaper to report it correctly the first time.

Some tax software will not let you file without entering 1095-A information if the IRS has a record of it being issued to you. This is a built-in safeguard to prevent this problem.

Reconciliation limits for lower-income filers

The IRS caps how much subsidy you have to pay back if your income is below certain thresholds. For 2023, if your income was under 200% of the federal poverty line, you owe back no more than $300. Between 200% and 300% of poverty, the cap is $750. Between 300% and 400%, it is $1,200. These caps apply only to the repayment—if your income was higher, you still owe the full amount.

These thresholds change each year. When you file, your tax software will apply the current year's cap automatically. The cap protects lower-income people from owing back large amounts of subsidy if their income estimate was significantly off.

The cap does not prevent reconciliation from reducing your refund to zero or creating a balance due. It only limits how much of the overpaid subsidy you have to repay. If the overpayment exceeds the cap, the excess is forgiven.

How to estimate the impact before you file

You can calculate the rough reconciliation amount yourself before you file. Gather your 1095-A and your income documents (W-2s, 1099s, business records). Add up your total income for the year. Then use the IRS income limits for your household size and filing status to see what subsidy you should have received at that income level.

The IRS publishes subsidy tables each year on its website. Find your income and household size, and the table shows the maximum subsidy you should have gotten. Compare that to the total shown in Box 2 of your 1095-A. The difference is roughly what will adjust your refund.

This is an estimate only—your tax software will do the exact calculation when you file, and the result may differ slightly depending on credits, deductions, and other factors. But it gives you a sense of whether the reconciliation will be large or small.

Frequently Asked Questions

Can I avoid reconciliation by not claiming the subsidy I received?

No. The subsidy is not optional—it was paid to your insurance company on your behalf during the year. The IRS knows about it from the 1095-A. Reconciliation happens whether you claim it or not. You must report the form and let the IRS adjust your refund accordingly.

What if I received a 1095-A but did not actually use the insurance?

You still must report it. The form reports the subsidy paid on your behalf, not whether you used the coverage. If you enrolled, received subsidies, and then did not use the plan, the reconciliation still applies. Report the 1095-A and let the calculation proceed.

Does reconciliation affect my refund if I owe taxes instead of getting a refund?

Yes. If you owe the IRS money, reconciliation increases what you owe. If you are getting a refund, reconciliation reduces it. Either way, the subsidy overpayment is deducted from whatever the IRS owes you or added to what you owe them.

Can I file my taxes without the 1095-A if I have not received it yet?

You can file, but it is risky. If the IRS has a record of the form being issued, your return may be held for review. It is better to wait for the 1095-A to arrive or contact the marketplace to request a copy before you file.

What if the 1095-A shows the wrong subsidy amount?

Contact the marketplace that issued it and ask for a corrected form. If the error is significant, the marketplace may issue a corrected 1095-A before the filing deadline. If you file before receiving the correction, you can file an amended return once you have the right form.
