State tax refunds are generally not taxable on your federal return, but there are exceptions based on whether you itemized deductions the year you paid the state tax
Most people who receive a state income tax refund do not owe federal tax on it. The IRS treats state tax refunds differently depending on how you filed your previous year's return. If you took the standard deduction, your state refund is not taxable. If you itemized deductions and claimed a state income tax deduction, you may owe federal tax on part or all of the refund—but only the amount that reduced your federal taxable income in the prior year.
The rule exists because of how deductions work: when you deduct state taxes paid, you lower your federal taxable income. When the state refunds that money, the IRS sees it as a recovery of a deduction you claimed. You are not taxed on the full refund, only on the portion that actually saved you federal tax.
Key Takeaways
- State tax refunds are not taxable federally if you used the standard deduction in the year you paid the state tax.
- If you itemized deductions and claimed state income tax as a deduction, part of your refund may be taxable on your federal return.
- You only pay federal tax on the refund amount that exceeded your standard deduction in the prior year.
- The IRS will send you a Form 1099-G if your state refund is large enough, and you must report it on your federal return.
- Property tax and sales tax refunds follow the same rule as income tax refunds.
When you used the standard deduction
If you claimed the standard deduction on your previous year's federal return, your state income tax refund is not taxable. This is the simplest scenario. You paid state income tax with after-tax dollars (money that did not reduce your federal taxable income), so when you get the refund, it is straightforward a return of your own money.
The standard deduction for 2024 was $14,600 for single filers and $29,200 for married filing jointly. Most taxpayers use the standard deduction because it is larger than their itemized deductions would be. If this was you, you do not report the state refund on your federal return at all.
When you itemized deductions
If you itemized deductions in the year you paid the state tax, the situation is different. When you itemize, you list out specific deductions—including state income tax, property tax, and sales tax—instead of taking the standard deduction. The total of your itemized deductions reduces your federal taxable income.
When you receive a state tax refund, the IRS treats it as a recovery of a deduction you claimed. You owe federal tax on the refund, but only up to the amount by which your itemized deductions exceeded the standard deduction in that year. For example, if your itemized deductions totaled $35,000 and the standard deduction was $29,200, your deductions exceeded the standard by $5,800. If you receive a $3,000 state refund, you would owe federal tax on the full $3,000 because it is less than the $5,800 excess. If you received a $7,000 refund, you would owe tax on only $5,800.
How to report the refund on your federal return
If your state refund is taxable, you will receive a Form 1099-G from your state tax agency. This form shows the refund amount in Box 1a. You must report this on your federal return, typically on Schedule 1 (Form 1040), line 1, labeled "Other income."
If your refund is not large enough to trigger a 1099-G (the threshold varies by state, usually between $10 and $20), you may still owe tax on it if you itemized deductions. In that case, you report it yourself on Schedule 1. Keep your state refund documentation so you can show the amount if the IRS asks.
The year you report the refund is the year you received it, not the year you paid the original state tax. If you received a refund in 2024 for 2023 taxes, you report it on your 2024 federal return.
Property tax and sales tax refunds
The same rule applies to refunds of property tax and sales tax. If you itemized deductions and claimed these taxes, a refund of either one is taxable on your federal return to the extent it exceeded your standard deduction in the prior year. If you used the standard deduction, neither property tax nor sales tax refunds are taxable.
This matters most for property tax refunds, which can be substantial if your county reassesses your home value downward or if you successfully appeal an assessment. Sales tax refunds are less common but can occur if you overpaid or if a state corrects an error in your account.
What happens if you did not receive a 1099-G
Some states do not issue 1099-G forms for small refunds, or they may issue them late. If you know you received a refund and it should be taxable, you can report it yourself on Schedule 1 even without the form. The IRS may cross-reference state records, so it is better to report it voluntarily than to wait for a notice.
If you are unsure whether your refund is taxable, gather your prior-year tax return and your state refund notice. Compare your itemized deductions to the standard deduction for that year. If your itemized deductions were higher, your refund is likely taxable. If you used the standard deduction, it is not.
Frequently Asked Questions
Do I have to pay federal tax on my entire state refund?
No. You only pay federal tax on the portion of the refund that reduced your federal taxable income in the prior year. If you used the standard deduction, none of it is taxable. If you itemized, only the amount by which your deductions exceeded the standard deduction is taxable.
What if I received a state refund but did not get a 1099-G?
You may still owe federal tax on it if you itemized deductions. Report the refund on Schedule 1 of your federal return. Keep your state refund documentation in case the IRS asks for proof of the amount.
Does a state tax refund affect my federal refund or tax bill?
Only if the refund is taxable. If you itemized deductions, reporting the refund as income increases your federal taxable income, which may reduce your federal refund or increase the tax you owe. If you used the standard deduction, it has no effect on your federal return.
Can I claim the state tax I paid again if I get a refund?
No. When you receive a refund, it reduces the amount of state tax you actually paid that year. You cannot deduct the full amount you sent to the state if some of it came back to you. The deduction should reflect only the net amount you paid after the refund.
What if I moved to a state with no income tax after paying state taxes?
The rule is based on your tax situation in the year you paid the tax, not where you live when you receive the refund. If you itemized deductions in the year you paid the state tax, your refund is taxable on your federal return, regardless of where you live now.
