State tax refunds are taxable on your federal return only if you claimed the state tax deduction the year you paid those taxes
A state tax refund becomes taxable federal income when you deducted state income taxes on your federal return in the year you paid them. The IRS calls this the tax benefit rule: you only owe federal tax on a refund if you received a tax benefit from deducting those payments in the first place.
If you took the standard deduction instead of itemizing, your state tax refund is not taxable. If you itemized and claimed state income taxes as a deduction, the refund is taxable. The year the refund arrives does not matter — what matters is whether you deducted those state taxes on a prior-year federal return.
You will report the taxable portion on Form 1040 as other income. The IRS sends you Form 1099-G if the refund is $10 or more, though some states use different thresholds or do not issue the form at all.
Key Takeaways
- State tax refunds are taxable only if you itemized deductions and claimed state income taxes on your federal return in the year you paid those state taxes.
- If you took the standard deduction, your state refund is not taxable federal income, even if it is a large amount.
- The IRS uses Form 1099-G to report state refunds of $10 or more, but not all states issue this form or use the same threshold.
- You report taxable state refunds on Form 1040 as other income in the year you receive the refund, not the year you paid the state taxes.
- Some states do not tax income at all, so residents of those states will never have a taxable state refund.
How the tax benefit rule determines what you owe
The tax benefit rule is straightforward: you pay federal tax on a refund only if you saved federal taxes by deducting the original payment. If you did not deduct the state taxes, you did not get a federal benefit, so the refund is not taxable.
In 2023, for example, if you itemized deductions and claimed $5,000 in state income taxes paid, you reduced your taxable federal income by $5,000. When you receive a state refund in 2024, part of that refund is money the IRS effectively gave you a tax break on. That portion becomes taxable income in 2024.
If you took the standard deduction in 2023 instead, you did not deduct any state taxes. A state refund in 2024 is simply money returned to you — not a tax benefit you need to repay to the IRS.
When you itemized versus when you took the standard deduction
Your filing status and total deductions determine which route you chose. If your itemized deductions (state taxes, mortgage interest, charitable donations, and others combined) exceeded the standard deduction for your filing status, you itemized. Otherwise, you took the standard deduction.
The standard deduction for 2023 was $13,850 for single filers, $27,700 for married filing jointly, and $20,800 for head of household. If your state taxes alone were close to or above these amounts, you likely itemized. If your state taxes were $1,000 or $2,000 and you had no other deductions, you almost certainly took the standard deduction.
You can find which method you used by looking at your prior-year tax return. Line 12 on Form 1040 shows your standard deduction amount. If that line is blank or shows zero, you itemized. If it shows a dollar amount, you took the standard deduction.
Partial refunds and the proration rule
If you paid state taxes across multiple years and only part of your refund relates to taxes you deducted, only that portion is taxable. The IRS requires you to prorate the refund based on how much of the original payment you deducted.
This matters most when you switch from itemizing to taking the standard deduction, or vice versa. Suppose you paid $6,000 in state taxes in 2022 and deducted all of it. In 2023, you took the standard deduction. In 2024, you receive a $6,000 refund for overpayment in 2022. The entire $6,000 is taxable, because you deducted the full amount in 2022.
If instead you received a $3,000 refund for 2022 and a $3,000 refund for 2023, only the 2022 portion would be taxable (assuming you deducted 2022 taxes but not 2023 taxes). You would report $3,000 as other income.
States with no income tax and special cases
Nine states have no income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only dividends and interest, not wages). Residents of these states will never receive a state income tax refund, so the question does not apply.
Some states refund portions of taxes that are not income tax — sales tax, property tax, or credits like the Earned Income Tax Credit. These refunds follow different rules. A state sales tax refund is generally not taxable. A state EITC refund may be taxable depending on whether you claimed the federal EITC and the state's specific rules.
If you are unsure whether a particular state refund is income tax or another type, check the Form 1099-G or contact the state tax agency directly. The form box 1 shows state income tax refunds; other boxes show different types of refunds.
Reporting the refund on your federal return
You report a taxable state refund on Form 1040, line 21 (other income). You do not need to attach the Form 1099-G unless the IRS requests it, but keep it with your records.
If the state refund is not taxable (because you took the standard deduction), you do not report it anywhere. You simply keep the money and do not include it on your return.
Some tax software will ask you directly whether you itemized and whether you received a state refund. If you answer yes to both, the software will calculate the taxable amount and place it on line 21 automatically. If you file by hand, you will need to determine the taxable portion yourself using the proration rule above.
What to do if you did not receive a Form 1099-G
The IRS requires states to issue Form 1099-G for refunds of $10 or more, but not all states follow this rule consistently. Some states use a higher threshold ($50 or $100), and some do not issue the form at all. If you received a refund but no form, you still owe federal tax on the taxable portion.
Check your state tax agency's website or contact them directly to confirm the refund amount. You can then report it on your federal return even without the form. The IRS has records of state refunds through data-sharing agreements with state agencies, so underreporting can trigger a notice later.
If you itemized in the prior year and received a state refund in the current year, assume it is taxable unless you have documentation showing otherwise. It is safer to report it and let the IRS correct you if needed than to omit it and face penalties.
Frequently Asked Questions
Do I have to report a state refund if I did not get a Form 1099-G?
Yes, if the refund is taxable (you itemized and deducted state taxes). The form is a reporting convenience, not a requirement for you to include the refund on your return. The IRS knows about the refund through state records, so omitting it can trigger a notice.
What if I itemized in one year but took the standard deduction the next year?
Only the refund for taxes you deducted is taxable. If you itemized in 2022 and took the standard deduction in 2023, a 2022 refund received in 2024 is taxable, but a 2023 refund is not. You may need to prorate if the refund covers both years.
Is a state property tax refund taxable?
State property tax refunds follow the same rule as income tax refunds: taxable only if you deducted the property taxes on your federal return. Most people who deduct property taxes itemize, so the refund is likely taxable. Check whether you itemized in the year you paid the taxes.
Can I reduce my taxable refund by claiming a loss on my state taxes?
No. The tax benefit rule looks only at whether you deducted the original payment, not whether you overpaid or underpaid. If you deducted $5,000 in state taxes and received a $5,000 refund, the full refund is taxable, even if you owed money to the state in other years.
What if my state refund is for a credit, not an overpayment of taxes?
State credits (like a state EITC or property tax credit) are handled differently than income tax refunds. Check the Form 1099-G box number or contact your state to determine the type of refund. Some state credits are taxable, others are not, depending on whether they reduced your state tax liability.
