A Form 1095-A reduces your refund because it reports health insurance subsidies you received during the year

Form 1095-A is the document that tracks advance premium tax credits — money the government sent directly to your insurance company to lower your monthly premiums. When you file your taxes, the IRS compares what you actually received against what you were supposed to receive based on your real income. If you got more in subsidies than you were may have access to to, you have to pay some or all of it back, which reduces your refund or increases what you owe.

The reduction happens because the IRS is settling accounts. You estimated your income when you signed up for insurance, the government sent you credits based on that estimate, and now that you know your actual income, the math gets corrected. If your actual income was higher than you predicted, your subsidy was too generous, and the overpayment comes out of your refund.

Key Takeaways

  • Form 1095-A reports subsidies your insurance company received on your behalf, not money you received directly.
  • The IRS compares your estimated income (when you signed up) to your actual income (when you file taxes) and adjusts your refund accordingly.
  • If your actual income was higher than your estimate, you received too much in subsidies and must repay the difference, which reduces your refund.
  • If your actual income was lower than your estimate, you may have received too little in subsidies and could get an additional refund.
  • The amount of the reduction depends entirely on the gap between what you estimated and what you actually earned.

Why the IRS uses Form 1095-A to adjust your refund

When you enroll in health insurance through the marketplace (Healthcare.gov or your state's equivalent), you report your expected household income for that year. The IRS uses that number to calculate how much in subsidies you should receive. The subsidy goes directly to your insurance company each month to reduce your premium.

By tax time, you know your actual income. If it was higher than you estimated, you received more in subsidies than you deserved. If it was lower, you received less. Form 1095-A is how the insurance company reports to the IRS exactly how much in subsidies went to your account. The IRS then recalculates what you should have received based on your actual income and adjusts your refund to settle the difference.

This is not a penalty — it is a correction. The government is not punishing you for estimating wrong; it is balancing the books so that you pay the right amount in total.

When a 1095-A increases your refund instead

If your actual income turned out to be lower than you estimated when you signed up for insurance, the opposite happens. You received less in subsidies than you were may have access to to. When you file taxes and report your real income, the IRS calculates that you should have gotten more help. The difference gets added to your refund.

This is one reason people sometimes get a larger refund than they expected. The subsidy adjustment can work in your favor if your income dropped during the year — due to job loss, reduced hours, or other circumstances — and you did not update your estimate on the marketplace.

How to find the subsidy amount on your 1095-A

Form 1095-A has 14 lines. The two that matter most for your refund are Line 1 (monthly enrollment information) and Line 2 (monthly premium amounts). The insurance company fills these in automatically.

The key number for the IRS is in Box 2 on each line — the monthly premium your plan actually cost. The subsidy amount is calculated by the IRS during tax filing, not printed on the form itself. Your tax software or tax preparer will use the information from your 1095-A to recalculate your subsidy and compare it to what you received.

You should receive your 1095-A by January 31 of the year after you had the insurance. If you do not receive it by early February, contact your insurance company directly — you will need it to file your taxes accurately.

What happens if your income changed mid-year

If you had a major change in income during the year — a job loss, a new job, a significant raise, or a change in household size — you could have updated your income estimate on the marketplace. When you update, the IRS recalculates your subsidy for the months going forward. This means your 1095-A may show different subsidy amounts for different months.

If you did not update and your income changed significantly, the refund adjustment could be large. For example, if you lost your job in June and your income dropped by half, but you did not report it until tax time, you may have received too much in subsidies for the first six months and too little for the last six months. The 1095-A will show the actual amounts paid, and your refund will reflect the net difference.

The marketplace allows you to update your income estimate at any time during the year. Doing so keeps your monthly subsidy closer to what you actually deserve and reduces the size of the refund adjustment in April.

How much the 1095-A reduction typically is

There is no typical amount — it depends entirely on how far off your income estimate was. Someone who estimated correctly will see little to no adjustment. Someone who estimated $35,000 but actually earned $50,000 will see a larger reduction. Someone who estimated $50,000 but earned $35,000 will see a refund increase.

The IRS does have a reconciliation limit that protects lower-income filers. If your household income is below 400% of the federal poverty line (the threshold varies by household size and year), the amount you have to repay is capped. Higher-income filers have no cap and must repay the full overpayment. This limit exists to prevent people with very low incomes from facing large unexpected bills at tax time.

Steps to take if your 1095-A will reduce your refund

First, check that the information on your 1095-A is correct. Verify that your name, Social Security number, and the months of coverage match your records. If something is wrong, contact your insurance company and ask them to issue a corrected form.

Second, gather any other documents that show your actual income for the year — W-2s, 1099s, pay stubs, or business records. Your tax preparer or software will need these to calculate your actual income and determine the correct subsidy adjustment.

Third, do not skip reporting the 1095-A. You must include it with your tax return. If you do not report it, the IRS will notice the missing information and may delay your refund or send you a notice asking for it.

Frequently Asked Questions

Can I avoid the refund reduction by not reporting my 1095-A?

No. The insurance company sends a copy of your 1095-A to the IRS automatically. If you do not report it on your return, the IRS will catch the discrepancy and either adjust your refund themselves or send you a notice. Reporting it yourself is faster and prevents delays.

What if I lost my 1095-A or never received it?

Contact your insurance company and request a replacement. You can usually do this online through your account or by calling their customer service line. If it is late January or early February, ask them to email or mail it to you right away. You cannot file your return without it if you received marketplace insurance.

Does the 1095-A affect my refund if I did not get a subsidy?

No. If you paid the full premium yourself without any subsidy, your 1095-A will show zero subsidy amounts, and there is nothing to reconcile. The form is still required to be filed with your return, but it will not change your refund calculation.

Can I owe money instead of getting a refund because of the 1095-A?

Yes. If you received significantly more in subsidies than you were may have access to to and your refund is not large enough to cover the full repayment, you will owe the difference when you file. This is rare but can happen if your income increased substantially during the year and you did not update your estimate.

What if I think the subsidy amount on my 1095-A is wrong?

Contact your insurance company first. They may have made an error in reporting. If they confirm the amount is correct but you believe the subsidy was calculated incorrectly by the marketplace, you can dispute it with the marketplace directly. Keep records of any income changes you reported and when you reported them.
