State tax refunds are taxable income on your federal return if you itemized deductions the year you paid the state tax

Whether you owe federal tax on a state refund depends on one thing: did you deduct state taxes on your federal return the year you paid them? If you itemized deductions (rather than taking the standard deduction), you deducted state income tax or state sales tax. When you get that money back as a refund, the IRS treats it as income you need to report.

If you took the standard deduction instead, your state refund is not taxable federally. You did not deduct the state tax in the first place, so there is nothing to reverse.

The IRS calls this the tax benefit rule. You get a deduction one year, then get the money back the next year. The agency wants to tax the refund because you already got a tax break from the original deduction.

Key Takeaways

  • State tax refunds are taxable on your federal return only if you itemized deductions and claimed state income tax or sales tax as a deduction the prior year.
  • If you took the standard deduction, your state refund is not taxable federally, and you do not report it.
  • You report the refund on Form 1040 as "other income" in the year you receive it, not the year you paid the original tax.
  • Some states also tax refunds from other states, but most do not; check your state's rules if you moved or received a refund from a different state.
  • The amount you report is only the refund itself, not the original tax payment.

How the tax benefit rule works in practice

Here is the sequence: In 2023, you paid $8,000 in state income tax. You itemized deductions on your 2023 federal return and claimed that $8,000 as a deduction, which lowered your federal taxable income. In 2024, the state refunds you $2,000 because you overpaid. That $2,000 is now taxable income on your 2024 federal return.

You do not report the full $8,000 you originally paid. You report only the $2,000 refund you received. The IRS is taxing the portion of your original deduction that came back to you.

If you had taken the standard deduction in 2023 instead, you would not have deducted the $8,000 at all. The $2,000 refund in 2024 would not be taxable, because you never got a tax benefit from paying it in the first place.

Which state refunds are taxable and which are not

State income tax refunds are the most common type. If you overpaid state income tax and got a refund, it is taxable on your federal return if you itemized.

State sales tax refunds (from claiming sales tax as a deduction instead of income tax) follow the same rule. If you deducted sales tax on your 2023 return and got a refund in 2024, that refund is taxable federally.

Other state refunds—property tax refunds, business tax refunds, or credits you received—are generally not taxable federally unless they relate to a deduction you claimed. If you are unsure whether a specific refund is taxable, the state that issued it can tell you, or you can ask a tax preparer.

How to report a state tax refund on your federal return

You report the refund on Form 1040, the main federal income tax form. The line for this is labeled "Other income" or sometimes "Refunds of state and local income taxes." The exact line number changes year to year, so check the current form instructions.

You report the refund in the year you receive it, not the year you paid the original tax. If you got the refund in January 2024, you report it on your 2024 return, even though you paid the tax in 2023.

You do not need to attach any documents to prove the refund. The state will send you a Form 1099-G (or similar) showing the amount. Keep that form with your records, but you do not mail it to the IRS.

State-level taxation of refunds from other states

A few states tax refunds you receive from other states. This is rare and usually applies only if you moved and received a refund from your former state of residence.

Most states do not tax refunds at all. If you moved from one state to another and received a refund from your former state, check your new state's tax rules or contact its revenue department. The rules vary widely and change, so there is no single answer that applies everywhere.

If you received a refund from a state where you do not live and do not work, you almost certainly do not owe that state tax on it. The refund is only taxable federally if you itemized deductions.

What happens if you did not itemize deductions

If you took the standard deduction in the year you paid the state tax, you have nothing to report. The refund is not taxable income on your federal return, and you do not include it anywhere on Form 1040.

This is true even if the refund is large. The tax benefit rule only applies if you got a deduction in the first place. No deduction means no taxable refund.

Many people take the standard deduction because it is simpler and often larger than their itemized deductions. If that was your situation, your state refund is clean—no federal tax owed on it.

Refunds and the standard deduction limit

The SALT cap (state and local tax cap) limits how much state and local tax you can deduct on your federal return. As of 2024, you can deduct up to $10,000 per year in state income tax, property tax, and sales tax combined.

If you paid more than $10,000 in state taxes but only deducted $10,000 on your federal return, and then received a refund, only the portion of the refund that relates to the $10,000 you deducted is taxable. This is complex, and most people do not need to split it this way—but if you hit the SALT cap, keep records of what you deducted versus what you paid.

Frequently Asked Questions

Do I have to report a state tax refund if it is under $600?

Yes. There is no minimum threshold for reporting other income on your federal return. Even a small refund must be reported if you itemized deductions the year you paid the tax. The IRS does not have a dollar cutoff for this type of income.

What if I received a refund but I am not sure if I itemized?

Look at your prior-year tax return (the year you paid the state tax). If you see a line for state and local taxes deducted, you itemized. If you see "standard deduction," you did not. Your tax preparer or the IRS can also help you find this information if you do not have the old return.

Can I claim the refund as a deduction instead of reporting it as income?

No. The refund must be reported as income in the year you receive it. You cannot deduct it. The tax benefit rule is one-way: you got the deduction when you paid the tax, and you pay tax on the refund when you get it back.

What if the state refund was for a prior year (like a 2022 refund I got in 2024)?

You report it in the year you received it, which is 2024 in this example. The year the tax was paid does not matter for federal purposes. What matters is when the money came back to you.

Do I owe state tax on my state tax refund?

Almost never. States do not typically tax refunds of their own taxes. A few states tax refunds from other states under specific circumstances, but your home state does not tax a refund it issued to you. Check your state's rules if you moved or received a refund from a different state.
