Most federal tax refunds are not taxable, but state refunds sometimes are

A refund of federal income tax you overpaid is not taxable income. The IRS does not tax money you get back because you paid too much in the first place. However, a refund from your state can be taxable under federal law if you itemized deductions in the year you paid the state tax. This rule applies only to state income tax refunds, not federal ones.

The taxability of a state refund depends on whether you claimed a deduction for state taxes in the prior year. If you took the standard deduction instead, your state refund is not taxable. If you itemized and deducted state income tax, the refund counts as income in the year you receive it.

Key Takeaways

  • Federal income tax refunds are never taxable income, no matter how large they are.
  • State income tax refunds are taxable only if you itemized deductions and claimed a state tax deduction in the year you paid the state tax.
  • If you took the standard deduction, your state refund is not taxable even if you receive a large amount.
  • You report a taxable state refund on Form 1040 as "other income" in the year you receive the refund, not the year you paid the tax.

Why federal refunds are never taxable

A federal tax refund is your own money returned to you. When you overpay federal income tax through withholding or estimated payments, you are lending that money to the government interest-free. The refund is simply the government returning what you overpaid—it is not new income, so the IRS does not tax it.

This holds true whether your refund is $100 or $10,000. The size of the refund does not change its status. The IRS treats all federal refunds the same way: as a return of your own funds, not as taxable income.

When state refunds become taxable income

A state income tax refund is taxable under federal law only if you deducted state income tax on your federal return in the prior year. This rule exists because of how the tax code handles deductions: if you deducted the state tax payment, you received a federal tax benefit from it. When the state refunds part of that payment, the refund is treated as income to offset the benefit you already received.

The key question is which deduction method you used on your federal return for the year you paid the state tax. If you itemized deductions on Schedule A and included state income tax (or state and local taxes under the SALT deduction), then your state refund is taxable. If you took the standard deduction, your state refund is not taxable, because you received no federal benefit from the state tax payment in the first place.

How to know if your state refund is taxable

Look at your federal tax return for the year you paid the state tax. Find your Form 1040 and check whether you itemized deductions or took the standard deduction. You can find this on line 12 of the Form 1040, which shows either "Standard deduction" or the amount of itemized deductions you claimed.

If you itemized and claimed a deduction for state income tax on Schedule A (line 5a for state income tax, or line 5b if you claimed state and local sales tax instead), then your state refund is taxable. If you took the standard deduction, your state refund is not taxable, and you do not need to report it on your federal return.

Some taxpayers switch between itemizing and taking the standard deduction from year to year. You need to check only the return for the year you paid the state tax, not the year you receive the refund.

Reporting a taxable state refund on your tax return

If your state refund is taxable, you report it on Form 1040 in the year you receive the refund. The refund goes on line 1 of Schedule 1 (Additional Income and Adjustments to Income) as "other income," then transfers to line 8 of Form 1040. You do not report it in the year you paid the state tax—only in the year the state sends you the refund.

You will receive a Form 1099-G from your state if the refund is $10 or more. The form shows the refund amount in box 1. Use this form to report the amount, though you are responsible for reporting it even if you do not receive the form. Keep a copy of the Form 1099-G with your tax records.

If your state refund is not taxable because you took the standard deduction, you do not report it anywhere on your federal return. You can disregard the Form 1099-G if you receive one, though you should keep it for your records in case of an audit.

State refunds that are never taxable

Some states do not have income tax, so there is no refund to report. These states are Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you lived in one of these states when you paid taxes, you have no state income tax refund to worry about.

Additionally, refunds from state property tax, sales tax, or other non-income taxes are not taxable under federal law. The taxability rule applies only to state income tax refunds. If your state refunded sales tax or property tax, you do not report it on your federal return.

What happens if you do not report a taxable state refund

The IRS receives a copy of the Form 1099-G your state sends you. If you do not report the refund on your federal return and the IRS has a record of it, the IRS may send you a notice of underreported income. This can trigger an audit or a bill for additional tax plus interest and penalties.

The safest approach is to report the refund if you received a Form 1099-G and you itemized deductions in the year you paid the state tax. If you are unsure whether your refund is taxable, consult a tax professional or contact your state tax agency to confirm whether you itemized in the prior year.
