State refunds are taxable income only if you deducted the state tax that produced the refund in a prior year

A state tax refund is taxable federal income in the year you receive it, but only under one condition: you must have deducted that state tax on your federal return in the year you paid it. If you took the standard deduction instead of itemizing, your state refund is not taxable. If you itemized but did not deduct state income tax (or deducted less than the refund amount), only the portion you actually deducted becomes taxable.

This rule exists because of the tax benefit rule. The IRS taxes refunds of money you previously deducted, since the deduction already reduced your federal tax. Without this rule, you would get a federal tax benefit twice—once when you deducted the payment, and again by keeping the refund tax-free.

The refund itself does not determine taxability. Your prior-year return does. You need to know what you deducted in the year you paid the state tax, not what you paid in the year you received the refund.

Key Takeaways

  • State refunds are taxable only if you itemized deductions and deducted state income tax in the year you paid it.
  • If you took the standard deduction, your state refund is never taxable federal income.
  • You report the taxable portion on Form 1040 as "other income" in the year you receive the refund, not the year you paid the tax.
  • The IRS sends you Form 1099-G if your state refund exceeds $10, which shows the amount but not whether it is taxable to you.
  • State refunds are almost never taxable at the state level in the state that issued them.

How the standard deduction affects whether your refund is taxable

If you claimed the standard deduction on your federal return in the year you paid state income tax, your state refund is not taxable. The standard deduction is a flat amount you subtract from income without itemizing individual deductions. Because you did not deduct state tax as an individual item, there is no prior deduction to recapture, and the refund carries no federal tax consequence.

This is true regardless of how much state tax you paid or how large the refund is. A $5,000 state refund is completely tax-free federally if you took the standard deduction that year. The only place it might affect your taxes is at the state level, and most states do not tax their own refunds.

The standard deduction amount changes each year and depends on your filing status. For 2024, it ranges from $14,600 for single filers to $29,200 for married filing jointly. If your itemized deductions would have been less than this amount, you took the standard deduction automatically, even if you did not explicitly choose it.

When itemizing makes your state refund taxable

If you itemized deductions in the year you paid state income tax, you may have deducted state income tax, state sales tax, or both (up to the $10,000 cap on state and local taxes, or SALT). Any refund of state income tax you deducted becomes taxable federal income in the year you receive it.

The taxable amount equals the lesser of two figures: the refund itself, or the state income tax deduction you claimed. If you deducted $8,000 in state income tax and received a $3,000 refund, the refund is fully taxable because it is smaller than your deduction. If you deducted $2,000 in state income tax and received a $5,000 refund, only $2,000 is taxable.

Some taxpayers itemize but deduct only state sales tax, not state income tax. If that was your situation, your state income tax refund is not taxable, because you did not deduct the income tax in the first place. You need to look at your Schedule A from the prior year to know which taxes you actually deducted.

Where to report the taxable portion on your federal return

You report a taxable state refund on Form 1040, line 21, labeled "Other income." You do not need a separate form or schedule for this entry. Simply write "state refund" next to the amount so the IRS knows what the income is.

The refund is taxable in the year you receive it, not the year you paid the tax. If you paid state income tax in 2023 and received the refund in 2024, you report it on your 2024 return. This timing matters because it affects which tax year the income belongs to.

If the refund is large or you received multiple refunds, you may receive Form 1099-G from your state. This form reports the refund amount but does not determine whether it is taxable to you. You still need to decide based on whether you deducted that tax. The IRS uses Form 1099-G to cross-check your reporting, so report the taxable portion even if you did not receive the form.

State-level taxation of state refunds

Most states do not tax their own refunds. If you received a refund from your state income tax, that refund is generally not subject to state income tax in that state. A few states have different rules, but the majority treat refunds as non-taxable at the state level.

If you moved to a different state between paying the tax and receiving the refund, the refund is still not taxable in your new state. State refunds are typically considered income from the state that issued them, and most states do not tax income from other states' refunds.

Check your state's tax instructions or contact your state revenue department if you live in a state with unusual tax rules or if you received a refund from a state other than your current residence.

What Form 1099-G tells you and what it does not

Your state sends Form 1099-G when you receive a refund of $10 or more. The form shows the refund amount in Box 1a (state income tax refund). This form is informational—it tells the IRS you received a refund, but it does not tell the IRS whether that refund is taxable to you. That information depends entirely on your prior-year return, which only you and the IRS can see.

The IRS uses Form 1099-G to verify that you report the refund on your current-year return. If you received Form 1099-G and the refund is taxable to you, report it. If the refund is not taxable because you took the standard deduction, you do not report it, and the IRS will eventually match the 1099-G to your return and see that you correctly did not report it.

Do not assume that receiving Form 1099-G means the refund is taxable. The form is just a record of the refund amount. You determine taxability based on your prior-year deductions.

Refunds from other state taxes and local taxes

State income tax refunds follow the rule above. Refunds from other state or local taxes—property tax, sales tax, vehicle tax—are generally not taxable at the federal level, even if you deducted them. The tax benefit rule applies primarily to income taxes. Property tax and sales tax refunds are usually treated as a reduction of the original tax paid, not as new income.

Local income tax refunds follow the same rule as state income tax refunds: taxable if you deducted the local income tax in the prior year. Some cities and counties impose local income tax, and refunds of those taxes are subject to the same deduction-based rule.

If you are unsure whether a particular refund is taxable, check the type of tax it came from. Income tax refunds require the deduction test. Other tax refunds are usually not taxable.

Frequently Asked Questions

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

If the refund is taxable to you (because you deducted state income tax), you should report it even without Form 1099-G. The IRS may not have a record of the refund, but you still owe tax on it. If the refund is not taxable because you took the standard deduction, you do not report it regardless of whether you received the form.

What if I deducted state sales tax instead of state income tax?

A state income tax refund is not taxable if you deducted sales tax instead of income tax. The refund is only taxable if you deducted the specific tax being refunded. Check your Schedule A from the prior year to see which tax you chose to deduct.

Is a state refund taxable if I owe state taxes in a different year?

No. A refund from one tax year is taxable based on deductions from that same year, not on whether you owe taxes in other years. Owing state taxes in 2024 does not affect the taxability of a 2023 refund received in 2024.

Can I deduct a state refund as a loss on my federal return?

No. A state refund is not a deductible loss. If you deducted state income tax and later received a refund, the refund is taxable income, not a loss. The two transactions offset each other over time, but you cannot claim a loss.

What if my state refund was applied to next year's taxes instead of sent to me?

If your state applied the refund to your next year's tax bill instead of sending it to you, it is still taxable in the year you would have received it. The refund is taxable based on when it was issued or credited, not on whether you received cash. Report it in the year the state credited it to your account.
