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

A state tax refund is taxable income on your federal return, but only under one specific condition: you must have deducted state and local taxes (called SALT) on your federal return in the year you originally paid that state tax. If you took the standard deduction instead, your state refund is not taxable federally, even though you received it.

This rule exists because the IRS does not let you benefit twice from the same dollar. If you deducted your state taxes to lower your federal taxable income, a refund of those same taxes is income you need to report. If you never deducted them federally in the first place, there is nothing to reverse.

The refund itself does not change what you owe on your state return — your state already settled that when it issued the check. The question is only whether the federal government sees it as new income.

Key Takeaways

  • You report a state tax refund as income on your federal return only if you itemized deductions and deducted state taxes in the year you paid them.
  • If you took the standard deduction in the year you paid the state tax, your refund is not taxable federally, regardless of the amount.
  • The refund is reported on Form 1040, line 1, as part of your total income, not as a separate line item.
  • You will receive a Form 1099-G from your state showing the refund amount, which helps you track what to report.
  • The year you report the refund is the year you receive it, not the year the original tax was paid.

How the deduction rule works

When you file your federal return, you choose between two paths: itemizing deductions or taking the standard deduction. The standard deduction is a flat amount that reduces your taxable income without listing individual expenses. Itemizing means you add up specific deductions — mortgage interest, charitable gifts, state and local taxes — and use that total instead if it is larger than the standard.

If you itemized in the year you paid your state tax, you likely deducted those state taxes on Schedule A of your federal return. That deduction lowered your federal taxable income. When your state later refunds part of that tax, the IRS treats the refund as income that offsets the deduction you claimed. You report it so the two sides balance.

If you took the standard deduction in the year you paid the state tax, you never deducted state taxes at all. There is no deduction to reverse, so the refund does not create taxable income on your federal return. You keep the refund without reporting it as federal income.

Which year you report the refund

Report the refund in the tax year you receive it, not the year the original tax was paid. If you paid state taxes in 2022 but did not receive the refund until 2024, you report it on your 2024 federal return.

This timing matters because it determines which year's return you amend if you made a mistake. If you received a refund in 2024 and did not report it, you would correct your 2024 return, not the 2022 return where the original tax was paid.

How to report the refund on your federal return

You report a state tax refund on Form 1040, line 1, as part of your total income. It goes in the same section as wages and other income — there is no separate line for refunds. The amount combines with your other income to determine your total income for the year.

Your state will send you a Form 1099-G showing the refund amount. Keep this form with your tax records. If you file electronically, your tax software will usually prompt you to enter the refund amount, and the software will place it in the correct location on your return.

If you received a refund but did not receive a Form 1099-G, you still need to report it if you deducted state taxes the prior year. Contact your state tax agency to request the form, or report the amount based on your own records of the refund.

The difference between state and federal refunds

A federal tax refund — money the IRS returns to you — is never taxable on your federal return. You already paid federal tax to earn that money, so a refund of overpaid federal tax is not new income. The rule about deductions applies only to state refunds, because state taxes are deductible on your federal return.

If you received both a state refund and a federal refund in the same year, only the state refund might be taxable federally. The federal refund is straightforward a return of your own money and carries no tax consequence.

What happens if you did not itemize

If you took the standard deduction in the year you paid the state tax, you have no reporting requirement for the state refund on your federal return. The refund is yours to keep without reducing it by taxes or reporting it as income.

This is one reason some people benefit from itemizing in high-tax states: if you itemize and later receive a refund, the refund is taxable federally, but the original deduction still reduced your federal tax that year. The net effect depends on your tax bracket and the size of the refund. If you take the standard deduction, you avoid this complication entirely.

Frequently Asked Questions

Do I report a state refund if I took the standard deduction?

No. If you took the standard deduction in the year you paid the state tax, you did not deduct state taxes federally, so the refund is not taxable on your federal return. You do not need to report it.

What if I do not receive a Form 1099-G?

You still report the refund if you deducted state taxes the prior year. Contact your state tax agency to request the form. If they cannot provide one, report the refund amount based on your own records — the check stub, your state account, or correspondence from the state.

Is a local income tax refund treated the same way?

Yes. If you deducted local income taxes on your federal return in the year you paid them, a refund of those local taxes is taxable on your federal return. The rule applies to any state or local tax you deducted federally.

Can I amend my return if I forgot to report a state refund?

Yes. If you deducted state taxes the prior year and received a refund you did not report, file an amended Form 1040-X for the year you received the refund. Include the refund amount on line 1 of the amended return.

What if the refund was for overpaid estimated taxes I sent to the state?

The source of the refund does not matter — whether it came from overpaid withholding or overpaid estimated taxes. If you deducted state taxes federally in the year you paid them, the refund is taxable on your federal return in the year you receive it.
