State tax refunds are generally not taxable income on your federal return

A state tax refund you receive does not belong on your federal tax return as income in most cases. The IRS treats it as a return of money you already paid, not as new earnings. However, there is one exception: if you claimed the state tax deduction on your federal return in the year you paid those state taxes, you may owe federal tax on the refund itself.

This exception exists because of something called the tax benefit rule. If you deducted your state taxes on your federal return and got a federal tax benefit from that deduction, then the refund of those state taxes becomes taxable income in the year you receive it. The IRS wants to prevent you from getting a tax benefit twice — once when you deducted the payment and again when you get the money back.

Whether you actually have to report the refund depends on how much it is and whether you itemized deductions in the year you paid the state tax.

Key Takeaways

  • State tax refunds are not taxable federal income unless you claimed the state tax deduction on your federal return in the prior year.
  • If you itemized deductions and deducted state taxes, you must report the refund as income on your federal return in the year you receive it.
  • If you took the standard deduction instead of itemizing, your state refund is not taxable on your federal return.
  • The IRS Form 1040 Schedule 1 is where you report state tax refunds as income if they are taxable.
  • You will receive a Form 1099-G from your state if the refund meets the reporting threshold, usually $10 or more.

When the tax benefit rule applies to your state refund

The tax benefit rule kicks in only if you itemized deductions on your federal return in the year you paid the state taxes. Itemizing means you listed out deductions like state income tax, property tax, and mortgage interest instead of taking the standard deduction.

If you itemized and included state income tax as a deduction, then when you get a refund of that state tax, the IRS considers it taxable income. This is because you received a federal tax benefit from deducting it — the deduction lowered your federal taxable income. The refund reverses part of that benefit, so the IRS taxes it to even things out.

For example: In 2023, you paid $5,000 in state income tax and itemized deductions on your 2023 federal return, which included that $5,000. In 2024, your state sends you a $1,200 refund. That $1,200 is taxable income on your 2024 federal return because you got a federal tax benefit from the original deduction.

When your state refund is not taxable

If you took the standard deduction on your federal return instead of itemizing, your state tax refund is not taxable. The standard deduction is a flat amount the IRS lets you subtract from your income without listing individual deductions. Most taxpayers use it because it is simpler and often larger than itemizing.

Since you did not deduct the state tax payment on your federal return, you did not get a federal tax benefit from it. Therefore, the refund is not taxable — it is simply money returned to you that you already paid.

The year matters here. You need to look at what you did on your federal return in the year you paid the state tax, not the year you receive the refund. If you took the standard deduction in 2023 and paid state taxes in 2023, then a 2024 refund of those 2023 taxes is not taxable on your 2024 federal return.

How to report a taxable state refund on your federal return

If your state refund is taxable, you report it on Form 1040, Schedule 1, line 1 (Other Income). This is where the IRS wants all state and local tax refunds reported.

You will likely receive a Form 1099-G from your state showing the refund amount. Most states send this form if the refund is $10 or more, though some states have different thresholds. The form arrives by January 31 of the year after you receive the refund. You use the amount on the 1099-G to fill in Schedule 1.

If you file electronically, your tax software will usually prompt you to enter the refund amount and automatically place it in the correct location. If you file by hand, write the amount on Schedule 1, line 1, and attach it to your Form 1040.

What to do if you did not receive a Form 1099-G

If your state refund was small and your state did not send a 1099-G, you still need to report it if it is taxable. Check your state's website or contact the state tax agency to confirm the refund amount. Many states post refund information online or let you look it up by your tax ID number.

If you itemized deductions in the year you paid the state tax, report the refund on Schedule 1, line 1, even without a 1099-G. The IRS may cross-check state records, so it is better to report it than to skip it.

If you are unsure whether you itemized or took the standard deduction in the prior year, look at a copy of your federal return from that year. Your tax software or a copy you kept will show which option you chose.

State refunds and the standard deduction increase

Starting in 2018, the standard deduction increased significantly, and many taxpayers who used to itemize switched to the standard deduction. This means fewer people are subject to the tax benefit rule for state refunds. If you switched to the standard deduction in recent years, your state refunds are likely not taxable on your federal return.

However, some taxpayers still itemize — particularly those with high mortgage interest, large charitable donations, or significant property taxes. If you are in this group, you need to track whether you itemized in the year you paid the state tax to know if the refund is taxable.

Frequently Asked Questions

Do I report a state tax refund if I took the standard deduction?

No. If you took the standard deduction on your federal return in the year you paid the state tax, the refund is not taxable on your federal return and you do not report it. The tax benefit rule only applies if you itemized deductions.

What if I itemized in some years but not others?

Look at your federal return from the specific year you paid the state tax that is being refunded. If you itemized that year, the refund is taxable. If you took the standard deduction that year, it is not. Each year stands on its own.

Can I claim a loss if my state refund is smaller than what I deducted?

No. You report only the refund amount you actually received as income. You cannot claim a loss for the difference between what you deducted and what you got back. The refund is treated as income, not as a deduction reversal.

Does a state sales tax refund count as income?

State sales tax refunds follow the same rule as income tax refunds. If you deducted sales tax on your federal return (which is rare), the refund is taxable. Most taxpayers do not deduct sales tax, so most sales tax refunds are not taxable on the federal return.

What if my state refund is for a prior year I did not file a federal return?

If you did not file a federal return in the year you paid the state tax, you did not claim any deduction for it. Therefore, the refund is not taxable on your current federal return. The tax benefit rule only applies if you actually got a federal tax benefit from the original payment.
