State tax refunds are usually not taxable on your federal return, but there are exceptions
A state tax refund is generally not taxable income on your federal tax return. The IRS treats it as a return of money you already paid, not as new income. However, you only have to report it if you claimed the state tax deduction on your federal return in the year you paid that state tax. This rule is called the tax benefit rule, and it exists because you cannot benefit twice from the same dollar.
The practical result: most people do not report state refunds at all. You will only file Form 1040 Schedule 1 to report a state refund if you itemized deductions on your federal return in the prior year and claimed state and local taxes (SALT) as part of that deduction. If you took the standard deduction instead, your state refund is not taxable and you do not report it.
Key Takeaways
- State tax refunds are taxable on your federal return only if you claimed the state tax deduction on your prior year federal return.
- If you took the standard deduction on your federal return, your state refund is not taxable and requires no reporting.
- You report a taxable state refund on Form 1040 Schedule 1, line 1, as "other income" in the year you receive the refund.
- The amount you report is limited to the state tax deduction you actually claimed, not the full refund amount.
- This rule prevents you from getting a tax benefit twice on the same money.
Understanding the tax benefit rule
The tax benefit rule is the reason state refunds can be taxable at all. Here is how it works: when you file your federal return, you reduce your taxable income by claiming either the standard deduction or itemized deductions. If you itemized and claimed state income tax as part of that, you received a federal tax benefit from that state tax payment. When the state refunds that money to you, you are getting back dollars that already lowered your federal tax bill.
The IRS does not want you to benefit twice. So if you claimed the state tax deduction and later received a refund, you have to report that refund as income on your federal return. This way, the refund offsets the deduction you claimed, and you only get the tax benefit once.
If you took the standard deduction instead of itemizing, you did not claim any state tax deduction. Therefore, you did not get a federal tax benefit from paying state tax in the first place. When you receive a refund, there is no benefit to reverse, so the refund is not taxable.
When you must report a state refund
You must report a state refund as income only if all three of these are true:
- You received a refund of state income tax you paid in a prior year.
- You filed a federal return for that prior year.
- You itemized deductions on that federal return and claimed state and local taxes (SALT) as part of your itemized deductions.
The refund must be reported in the tax year you receive it, not the year you paid the state tax. For example, if you paid state tax in 2023, itemized deductions on your 2023 federal return, and received a refund in 2024, you report the refund on your 2024 federal return.
You report it on Form 1040 Schedule 1, line 1, labeled "other income." You do not need to file a separate form for the refund itself—just add it to your other income on Schedule 1.
How much of your refund is taxable
You do not necessarily report the entire refund amount as income. You report only the portion that relates to the state tax deduction you claimed on your federal return. This is usually the full refund, but not always.
For example, suppose you paid $5,000 in state income tax in 2023 and itemized deductions on your 2023 federal return. You claimed the full $5,000 as part of your SALT deduction. In 2024, the state refunds you $1,200. You report $1,200 as income on your 2024 federal return, because that is the amount of the refund that relates to the deduction you claimed.
However, if you had a SALT deduction limit—such as the $10,000 cap that applies to most taxpayers—and your total SALT deductions exceeded that limit, you may have claimed less than the full $5,000. In that case, you would report only the refund amount that relates to the portion you actually claimed.
State refunds and the SALT deduction cap
Most taxpayers face a $10,000 annual limit on state and local tax deductions (SALT), which includes state income tax, state sales tax, and property tax combined. This cap has been in place since 2018 and is set to remain through 2025 unless Congress changes it.
If your state and local taxes exceeded $10,000, you could only claim $10,000 on your federal return. When you receive a state income tax refund, you report it as income, but only up to the amount of state income tax you actually claimed. The refund does not trigger a taxable event for the portion of state tax that exceeded the cap and was not deducted.
Keep records of your state tax payments and the amount you claimed on your federal return. This makes it easier to calculate the taxable portion of any refund you receive later.
What happens if you did not itemize
If you took the standard deduction on your federal return, you did not claim any state tax deduction. This means you did not receive a federal tax benefit from paying state tax. When you receive a state refund, there is no tax benefit to reverse, so the refund is not taxable income on your federal return.
You do not report it anywhere on your federal return. The refund is yours to keep without any federal tax consequence. This is true even if the refund is large or if you received it in a different tax year than the one in which you paid the state tax.
The only exception would be if you had a very unusual situation where you claimed a credit related to state taxes (such as a state earned income tax credit), but this is rare and would be documented in your tax records.
How to report a state refund on your tax return
If you determine that your state refund is taxable, report it on Form 1040 Schedule 1, which is the supplemental income schedule filed with your Form 1040. On Schedule 1, line 1 is labeled "other income." Enter the amount of your state refund there.
You do not need to file a separate form or attach a statement explaining the refund. The IRS knows that state refunds can be taxable under the tax benefit rule, and Schedule 1 is the standard place to report them.
If you use tax software, the software will usually ask whether you received a state refund and whether you itemized deductions in the prior year. Answer those questions accurately, and the software will place the refund in the correct location on your return.
Frequently Asked Questions
Do I have to report a state refund if I took the standard deduction?
No. If you took the standard deduction on your federal return, you did not claim any state tax deduction, so your state refund is not taxable and does not need to be reported on your federal return.
What if I received a state refund but cannot remember whether I itemized?
Check your prior year federal tax return (Form 1040). It will show whether you claimed the standard deduction or itemized deductions. You can also contact the IRS or use IRS.gov to request a transcript of your prior year return.
Is a state tax refund ever taxable on my state return?
No. State tax refunds are not taxable to the state that issued them. They are only potentially taxable on your federal return, and only under the tax benefit rule described here.
If I received a refund but only claimed part of my state taxes as a deduction, do I report the whole refund?
No. You report only the portion of the refund that relates to the state tax deduction you actually claimed on your federal return. If you claimed $8,000 of state tax but received a $10,000 refund, you report $8,000 as income.
What if my state refund is very small—do I still have to report it?
Yes, if you itemized deductions in the prior year. The IRS requires reporting of all taxable refunds, regardless of size. However, the amount may be small enough that it does not change your tax liability significantly.
