State refunds report on line 1 of Form 1040, under "Other income"

A state tax refund you received in the current year goes on line 1 of Form 1040, in the section labeled "Other income." This is true whether you received the refund as a check, direct deposit, or credit applied to next year's state taxes. The IRS treats it as income in the year you actually receive it, not the year the state tax was originally filed.

You will also receive a Form 1099-G from your state tax authority showing the refund amount. This form arrives by January 31 and reports both the state income tax refund and any state unemployment benefits you received. The refund amount on your 1099-G should match what you enter on line 1 of your 1040.

The reason this matters: you may owe federal tax on the refund itself, depending on whether you itemized deductions in the year you paid the state tax. If you took the standard deduction, the refund is not taxable. If you itemized, you may have already deducted the state taxes you paid, so the refund reduces that deduction's value and becomes taxable income.

Key Takeaways

  • State tax refunds report on line 1 of Form 1040 in the year you receive them, regardless of when the original state return was filed.
  • You will receive a Form 1099-G from your state showing the refund amount, which must match your 1040 entry.
  • If you took the standard deduction in the year you paid state taxes, the refund is not taxable and you may not owe federal tax on it.
  • If you itemized deductions and deducted state taxes paid, the refund is taxable income because it reduces the deduction you already claimed.

Why the IRS counts state refunds as income

The federal tax code treats a refund as a recovery of a deduction. In the year you paid state income tax, you either deducted it (if you itemized) or you did not (if you took the standard deduction). A refund in a later year reverses part of that original transaction.

If you itemized and deducted $8,000 in state taxes, then received a $1,200 state refund the next year, that refund is taxable because you already got a federal tax benefit from the $8,000 deduction. The refund reduces the net benefit of that deduction, so the IRS counts it as income to balance the books.

If you took the standard deduction, you received no federal benefit from paying state taxes in the first place, so a refund of those taxes is not taxable. This is called the tax benefit rule: you only owe federal tax on a refund if you received a federal tax benefit from the original payment.

How to report the refund if you are unsure about itemizing

Check your prior-year tax return to see whether you itemized or took the standard deduction. If you itemized, the refund is taxable and goes on line 1. If you took the standard deduction, the refund is not taxable, and you may leave line 1 blank (or enter zero).

Some taxpayers use tax software that asks this question directly. Others receive a Form 1099-G and assume they must report the full amount. You do not have to report a refund on line 1 if you took the standard deduction in the year you paid the state tax, even if the 1099-G shows it.

If you are filing jointly and your spouse itemized while you took the standard deduction, only the portion of the refund attributable to your spouse's deduction is taxable. This requires separating the refund by person, which your state may not do automatically. Contact your state tax authority if you need a breakdown.

What happens if you do not report the refund

The IRS receives a copy of your Form 1099-G from your state. If you do not report the refund on your 1040 and the IRS thinks you should have, they will send you a notice asking for the difference in tax owed, plus interest and penalties. This usually happens months or even years after you file.

The notice will cite the 1099-G amount and ask why you did not report it. At that point, you can respond with your prior-year return showing that you took the standard deduction, which means the refund was not taxable. The IRS will review your response and either agree or assess the tax.

To avoid this, report the refund on line 1 if you itemized, and keep a copy of your prior-year return showing your deduction method. If you took the standard deduction, you can file an amended return or respond to an IRS notice with documentation that you did not itemize.

Refunds applied to next year's state taxes instead of received as cash

Some states allow you to explore a refund to next year's state tax liability instead of receiving it as a check or deposit. The IRS still counts this as a refund received in the year the state issued it, even though you did not touch the money.

For example, if your 2023 state return generated a $500 refund and you told the state to explore it to your 2024 estimated taxes, you still report the $500 on your 2024 federal 1040 (line 1) because you received the refund in 2024. The state will issue a 1099-G showing the amount applied, and that is what you report.

This matters because some taxpayers think an applied refund does not count as income. It does. The fact that the state held the money and credited it to your next year's bill does not change the reporting requirement.

State refunds from prior years and amended returns

If you filed your 1040 and later received a state refund from a prior year (for example, a refund from a state return you amended), you report that refund on the 1040 for the year you received it, not the year the original state return covered.

You may need to file an amended 1040 (Form 1040-X) for the year you received the refund if you did not originally report it. The amended return goes to the IRS, and you include the refund on line 1 of the amended 1040 for that year.

Keep the 1099-G or state documentation showing when you received the refund. This proves to the IRS which tax year the refund belongs in if you are audited or receive a notice.

Frequently Asked Questions

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

No. If you took the standard deduction in the year you paid state taxes, the refund is not taxable and you do not report it on line 1. The tax benefit rule means you only owe federal tax on a refund if you received a federal benefit from the original payment. Check your prior-year return to confirm which method you used.

What if I received a 1099-G but did not itemize?

You still do not have to report the refund on your 1040. The 1099-G is informational; it does not determine whether the refund is taxable. If you took the standard deduction, the refund is not taxable regardless of what the 1099-G says. Keep your prior-year return as proof in case the IRS asks.

Can I report only part of the refund on line 1?

Only if you itemized in the prior year but did not deduct all of your state taxes paid. For example, if you paid $10,000 in state taxes but only deducted $8,000 (due to limits), a $1,200 refund is only partially taxable. This is complex and usually requires a tax professional to calculate correctly.

What if my state refund arrived after I filed my 1040?

You will need to file an amended 1040 (Form 1040-X) for the year you received the refund, adding it to line 1. Do this within three years of the original filing date to avoid penalties. Include a copy of the 1099-G with your amended return.

Does a state refund affect my federal tax credits?

It can. If the refund pushes your income above a threshold for credits like the Earned Income Tax Credit or Child Tax Credit, you may lose part or all of the credit. Run your numbers through tax software or with a tax professional if you are close to a credit limit.
