A federal tax refund is not considered income, so the answer to whether a tax refund is considered income depends entirely on which refund you mean. Money the IRS sends back is your own overpayment coming home and is never taxable. A state or local income tax refund is different: it can be partly or fully taxable if you itemized deductions on last year’s federal return and those state tax payments actually lowered your federal tax bill.
Why a Federal Refund Is Never Taxable
When the IRS refunds you, it’s returning money you already paid in through withholding or estimated payments. That income was already reported and taxed on the return that produced the refund. Taxing the refund would mean taxing the same dollars twice.
The size of the refund doesn’t change this, and neither does the complexity of your return. Federal income taxes aren’t deductible on your federal return in the first place, so a federal refund can’t be reversing a prior deduction. There’s nothing for the IRS to recapture.
When a State or Local Refund Is Taxable
State and local income taxes are deductible on your federal return if you itemize on Schedule A. That deduction cuts your federal tax in the year you claim it. If the state later refunds some of what you paid, you effectively got a federal tax break on money you didn’t ultimately owe. The IRS recovers that break by treating the refund as income in the year you receive it.
Two things both have to be true for any part of a state refund to be taxable:
- You itemized deductions on the prior year’s federal return.
- The state income tax deduction you claimed actually reduced your federal tax.
If either one fails, the refund is tax-free. The most common way the second one fails is that you took the standard deduction. In that case, your state tax payments produced no federal benefit, and any state refund you get later is not taxable. You can ignore the Form 1099-G for reporting purposes, though the state still sends it.
The SALT cap can also knock out taxability. The federal deduction for state and local taxes is capped, and any state taxes you paid above the cap gave you no federal benefit. A refund attributable to that excess isn’t taxable either. The IRS has said directly that because of the cap, some itemizers don’t need to include a state refund in income at all.1Internal Revenue Service. IRS Issues Guidance on State Tax Payments
How Much of a State Refund Is Taxable
The tax benefit rule in Section 111 of the Internal Revenue Code stops you from getting a double benefit — deducting a payment one year and pocketing the refund tax-free the next — but it also protects you from reporting more than you actually benefited from.2Office of the Law Revision Counsel. 26 USC 111 – Recovery of Tax Benefit Items
The core comparison is between your prior year’s itemized deductions and the standard deduction you could have claimed instead. A state refund is taxable only up to the amount by which your itemized deductions exceeded that standard deduction. If your itemized total was at or below the standard deduction, itemizing gave you no extra benefit and the whole refund is tax-free.
A Partially Taxable Refund
A single filer receives a $1,500 state refund in 2026 based on their 2025 return. They itemized in 2025 and claimed $17,000 in total deductions. The 2025 standard deduction for a single filer was $15,750.3Internal Revenue Service. Publication 501 (2025), Dependents, Standard Deduction, and Filing Information
Their itemized deductions beat the standard deduction by $1,250. That’s the extra federal benefit itemizing produced. So even though the refund was $1,500, only $1,250 is taxable. The other $250 gave them no federal benefit and comes back tax-free.
A Fully Non-Taxable Refund
A married couple filing jointly gets a $2,000 state refund in 2026. Their 2025 itemized deductions came to $30,000. The 2025 joint standard deduction was $31,500. Because itemizing produced no extra benefit over the standard deduction, the full $2,000 refund is not taxable.
If You Deducted Sales Tax Instead
Schedule A lets you deduct either state income taxes or state general sales taxes, not both. If you chose sales tax on your prior return, a state income tax refund is generally not taxable, because you never deducted the tax that was refunded.4Internal Revenue Service. Publication 525 (2025), Taxable and Nontaxable Income There’s one wrinkle: if the income tax you could have deducted was larger than the sales tax you did deduct, the taxable portion of a refund is limited to the difference. In most sales-tax-deduction situations, that means the refund is either fully tax-free or only a small slice is taxable.
Interest Paid on a Late Refund Is Taxable
The refund itself may be tax-free, but any interest the IRS or a state agency pays you for taking too long to issue it is fully taxable. It’s income in the year you receive it, separate from the underlying refund.5Internal Revenue Service. 13.9 Million Americans to Receive IRS Tax Refund Interest
If the interest totals $10 or more, you’ll get a Form 1099-INT. Amounts below $10 are still taxable and still have to be reported.6Internal Revenue Service. Topic No. 403, Interest Received This trips people up because the refund and the interest often land in the same deposit. Check your IRS account or wait for the 1099-INT before assuming the whole payment was a tax-free refund.
Refunds Driven by Refundable Credits
Some refunds aren’t returns of overpaid tax at all. Refundable credits like the Earned Income Tax Credit, the refundable portion of the Child Tax Credit, part of the American Opportunity Tax Credit, and the Premium Tax Credit can pay you money even when you owed no tax.7Internal Revenue Service. Refundable Tax Credits These payments aren’t taxable. They aren’t reversing a prior deduction and they aren’t returning your own withheld dollars — they’re direct assistance through the tax system.
If your refund is a mix of overpaid withholding and refundable credits, the whole refund is tax-free.
Refunds That Got Seized Still Count
If a state refund never reached you because it was intercepted for unpaid child support, defaulted federal student loans, back taxes owed to another agency, or applied to next year’s estimated tax, the taxability analysis doesn’t change. The 1099-G shows the full refund amount, and the IRS treats it as constructively received.8Internal Revenue Service. Form 1099-G (Rev. March 2024) Certain Government Payments If the refund would have been taxable in your hands, it’s still taxable when the state redirected it.
How to Report a Taxable State Refund
The state or local government sends Form 1099-G by January 31 of the year after the refund is issued, with the total refund in Box 2.9Internal Revenue Service. Instructions for Form 1099-G (03/2024) The IRS gets a copy of the same form.
The number on the 1099-G is not necessarily what you report. Run the tax benefit rule calculation first. The IRS provides a worksheet in the instructions for Schedule 1 (Form 1040) that compares your prior year’s itemized deductions to the standard deduction and tells you how much of the refund, if any, is taxable.4Internal Revenue Service. Publication 525 (2025), Taxable and Nontaxable Income
Put the taxable amount on Schedule 1, Line 1, “Taxable refunds, credits, or offsets of state and local income taxes.”10Internal Revenue Service. Schedule 1 (Form 1040) 2025 Additional Income and Adjustments to Income It flows into your adjusted gross income on Form 1040. If the taxable amount comes out lower than the 1099-G figure, report the lower amount.
No 1099-G doesn’t mean no reporting obligation. If you had a taxable refund, you still have to report it — check your state tax account for the amount. And if the 1099-G looks wrong, ask the issuing agency for a corrected form before you file.11Internal Revenue Service. 1040 (2025) Instructions
