State refunds are taxable on your federal return only if you deducted state taxes on your federal return the year you paid them

The rule is straightforward: if you claimed a deduction for state income taxes (or state sales taxes) on your federal return in the year you paid them, any refund you receive from the state is taxable income on your federal return. If you did not deduct state taxes that year, the refund is not taxable federally.

This is called the tax benefit rule. You cannot deduct a tax payment and then receive the refund tax-free—that would let you claim the deduction twice. The IRS treats the refund as a correction: you deducted too much, so the refund is income in the year you receive it.

The timing matters. A state refund is taxable based on whether you deducted state taxes in the year you paid them, not the year you receive the refund. If you paid state taxes in 2023 and deducted them on your 2023 federal return, a refund arriving in 2024 is taxable on your 2024 federal return.

Key Takeaways

  • State refunds are taxable federally only if you deducted state income or sales taxes on your federal return in the year you paid them.
  • The IRS sends you a Form 1099-G showing the refund amount, which you report on your federal return in the year you receive it.
  • If you took the standard deduction instead of itemizing, your state refund is not taxable federally.
  • The taxable amount is only the portion of the refund that relates to taxes you actually deducted—if you deducted $5,000 in state taxes and received a $7,000 refund, only $5,000 is taxable.

How the IRS knows about your state refund

Your state tax agency reports refunds to the IRS on Form 1099-G. You receive a copy, and the IRS receives a copy. The form shows the refund amount and the tax year it relates to.

If you received a state refund in 2024, you should have received a Form 1099-G by January 31, 2025. Check the box labeled "State income tax refund" to see the amount. If the form shows a refund but you did not deduct state taxes that year, you will need to explain that on your federal return or in your records.

Some states do not issue 1099-Gs for small refunds—typically under $10. If you received a small refund and no form arrived, you still need to report it if you deducted state taxes, but the IRS is less likely to match it to your return.

When state refunds are not taxable

If you took the standard deduction on your federal return instead of itemizing deductions, your state refund is not taxable. The standard deduction is a flat amount you can deduct without listing individual expenses. Because you did not deduct state taxes, there is no tax benefit to reverse, and the refund is yours to keep.

You also avoid federal tax on a state refund if you deducted state sales taxes instead of state income taxes in the year you paid them. Some taxpayers choose this option in states with no income tax or low income tax. If you deducted sales taxes and later received an income tax refund, the refund is not taxable because it does not relate to the deduction you claimed.

Similarly, if you paid state taxes in one year but did not deduct them (perhaps because your deductions fell short of the standard deduction), a refund in a later year is not taxable. The refund only reverses a deduction you actually claimed.

Reporting the refund on your federal return

You report a taxable state refund on Form 1040, Line 1 (or the equivalent line on your tax form). This is the line for "other income." You do not report it as a deduction or a credit—it is additional income for the year you received it.

If the refund is small and the IRS does not match it to a 1099-G, you may not be required to report it. However, if you received a Form 1099-G, the IRS expects to see it reported, and failing to do so can trigger a notice or audit.

If you received a 1099-G but believe the refund should not be taxable (for example, because you took the standard deduction), you can still report the refund and then claim an offsetting deduction. This is done on Form 1040, Schedule 1, under "Other income adjustments." You would report the refund as income and then subtract it as a non-taxable return of capital. Keep documentation showing you did not deduct state taxes in the year you paid them.

Partial refunds and the tax benefit rule

If you deducted $8,000 in state taxes but received a $10,000 refund, only $8,000 is taxable federally. The extra $2,000 might be interest or a credit the state applied. You report only the portion that relates to the taxes you deducted.

Your Form 1099-G will show the total refund amount, not the breakdown. If the refund exceeds the taxes you deducted, you will need to calculate the taxable portion yourself and document it. Keep your state tax return and the refund notice to show the IRS how you arrived at the taxable amount.

If you are unsure whether the entire refund is taxable, contact your state tax agency and ask for a breakdown. They can tell you what portion relates to income tax versus other credits or interest.

State refunds from prior-year returns

If you filed an amended state return or the state corrected your return after you filed, the refund you receive relates to the year the taxes were originally paid, not the year you receive the refund. The taxable status depends on whether you deducted state taxes in that original year.

For example, if you paid 2022 state taxes, deducted them on your 2022 federal return, and received a refund in 2025 due to a state audit, the refund is taxable on your 2025 federal return (because you deducted the taxes in 2022). You would report it on your 2025 Form 1040.

Frequently Asked Questions

Do I have to report a state refund if I did not receive a 1099-G?

If you deducted state taxes and received a refund, you should report it even without a 1099-G. The IRS may not catch it, but if they do, you could face penalties. If you took the standard deduction, you do not have to report it.

What if I deducted state taxes but the refund was smaller than I expected?

Report the actual refund amount you received, not the amount you deducted. Only the refund itself is taxable income. If you deducted $5,000 but received a $3,000 refund, report $3,000 as income.

Can I claim a loss if my state refund is less than the taxes I paid?

No. A refund that is smaller than your deduction is not a loss—it just means you overpaid by less than you thought. You report only the refund amount as income, and the difference stays with you as a net cost of the taxes you paid.

Does a state property tax refund count the same way?

Yes, if you deducted property taxes on your federal return. Property tax refunds follow the same tax benefit rule as income tax refunds. If you deducted property taxes and received a refund, it is taxable federally in the year you receive it.

What if I am not sure whether I itemized or took the standard deduction?

Check your prior-year federal tax return. If Line 12 on Form 1040 shows the standard deduction amount, you took the standard deduction and your state refund is not taxable. If you see itemized deductions listed, you itemized and the refund is taxable.
