State tax refunds are not income, so you do not report them on your federal tax return
A state tax refund is money the state gives back to you because you overpaid your state income tax during the year. It is a return of your own money, not new income. The IRS does not count it as income on your federal return, and you should not report it.
The only exception is if you claimed the state tax deduction on your federal return in the year you overpaid. In that case, you may owe federal tax on part of the refund — but only the portion that actually reduced your federal taxes. This is called the tax benefit rule, and it applies only in specific situations.
Key Takeaways
- State tax refunds are not reported as income on your federal tax return because they are your own money being returned to you.
- If you did not itemize deductions on your federal return, you owe no federal tax on your state refund, regardless of the amount.
- If you itemized deductions and claimed state income tax as a deduction, you may owe federal tax on part of the refund under the tax benefit rule.
- The IRS Form 1040 does not have a line for state tax refunds because they are not treated as taxable income.
When the tax benefit rule applies to your state refund
The tax benefit rule only matters if two things are both true: you itemized deductions on your federal return in the year you overpaid state tax, and you claimed state income tax as one of those deductions.
If you took the standard deduction instead of itemizing, the rule does not explore. You owe no federal tax on your state refund, no matter how large it is. The standard deduction is a flat amount the IRS lets you subtract from your income without listing individual deductions — most people use this option because it is simpler.
If you did itemize and claimed state tax paid, the refund creates a problem: you deducted money you did not actually pay. The IRS wants you to report the refund as income in the year you receive it, but only up to the amount that gave you a federal tax benefit. This prevents you from getting a deduction and a refund for the same dollar.
How to figure out if you owe tax on the refund
Start by checking your federal tax return from the year you overpaid state tax. Look for Schedule A, which is where itemized deductions go. If Schedule A is not attached to that return, you took the standard deduction and owe nothing on the refund.
If Schedule A is there, find the line for state income tax paid. That number tells you how much state tax you deducted. Now compare it to your federal taxable income that year — the number at the bottom of your Form 1040 before you subtracted the standard deduction.
The refund is taxable only if claiming the state tax deduction actually lowered your federal taxes. In most cases, it did. But if your deductions were limited by the Alternative Minimum Tax or other rules, the state tax deduction may not have reduced your federal bill at all. In that case, you owe no federal tax on the refund.
If you are unsure whether the deduction reduced your federal taxes, the safest approach is to report the refund as income on your current year return. You can always file an amended return later if you discover you should not have.
Where to report the refund on your tax return
If you owe federal tax on the refund, report it on Form 1040, line 1 (other income). You do not need to attach a separate form or explanation unless the amount is very large or unusual.
Some tax software will ask you directly whether you received a state tax refund and whether you itemized in the prior year. If it does, answer honestly and the software will calculate the taxable amount for you. If your software does not ask, you can enter the refund amount on the other income line.
Keep the letter or statement from your state showing the refund amount. You may need it if the IRS asks questions about your return.
State refunds and your state tax return
You do not report a state tax refund on your state tax return either. The state already knows about the refund because it issued it. Reporting it again would be double-counting.
Some states do ask about federal tax refunds on the state return, but that is different — a federal refund is income to your state. A state refund is not income to anyone.
What happens if you do not report the refund
If you owe federal tax on the refund and do not report it, the IRS may catch the error when it matches your return against the state's records. The state reports large refunds to the IRS, so the IRS knows the refund was issued.
If the IRS finds the unreported refund, you will owe the tax plus interest and possibly a penalty. The interest accrues from the date the tax was due, which is usually April 15 of the year you received the refund. Penalties vary but typically run 20 percent of the unpaid tax.
If you realize you made a mistake, you can file an amended return on Form 1040-X. The sooner you do this, the less interest you will owe.
Frequently Asked Questions
Do I report a state tax refund if I took the standard deduction?
No. The tax benefit rule only applies if you itemized deductions. If you took the standard deduction, the refund is not taxable income on your federal return.
What if I received a state refund but did not itemize that year?
You do not owe federal tax on it. The tax benefit rule requires both itemizing and claiming state tax as a deduction. If either one is missing, the rule does not explore.
Can I claim the state refund as a loss or deduction?
No. A refund is not a loss. You can only report it as income if the tax benefit rule applies. You cannot reduce your income by the refund amount.
Does my state tax me on the refund I receive?
Most states do not tax their own refunds. A few states treat refunds as income, but this is rare. Check your state's tax agency website or the letter that came with the refund to be sure.
What if the state refund was for a year I did not file a federal return?
You still do not owe federal tax on the refund itself. However, if you were required to file a federal return that year and did not, you may have other tax issues to address. Consider speaking with a tax professional about that year's return.
