Do You Have to Pay Taxes on Tax Refunds? State vs. Federal

Do you have to pay taxes on tax refunds? A federal income tax refund is never taxable. A state or local refund can be partly taxable, but only if you itemized deductions the year you paid those taxes and actually reduced your federal bill by doing so. Any interest the IRS tacks on to a late refund is taxable on its own, even when the refund itself is not.

Why Federal Refunds Are Never Taxable

A federal refund is money you already paid the government through withholding or estimated payments and are getting back because you overpaid. You were never allowed to deduct federal income taxes on your federal return, so the refund does not represent a recovered deduction.¹ No prior tax benefit means no income to report. You do not enter a federal refund anywhere on your return, no matter the size.

The same is true when a refundable credit like the Earned Income Tax Credit or the refundable portion of the Child Tax Credit produces a payment larger than the tax you owed. That payment is not income either, because the credit was never claimed as a deduction you later recovered.

When a State or Local Refund Is Taxable

State and local income tax refunds work differently because state taxes are one of the deductions you can claim on Schedule A. The rule that decides taxability is called the tax benefit rule, at 26 U.S.C. § 111. A recovered amount is income only to the extent the original deduction actually cut your federal tax.² That splits filers into two clean groups.

You Took the Standard Deduction

If you claimed the standard deduction for the year the state taxes were paid, the refund is not taxable. You never deducted the state taxes, so the refund is not a recovery of anything.³ For 2026, the standard deduction is $16,100 for single filers, $32,200 for joint filers, and $24,150 for heads of household.⁴

You Itemized

If you itemized and deducted state income taxes on Schedule A, some or all of a later refund is income. The taxable portion is capped at the amount by which your itemized deductions exceeded the standard deduction you could have taken.⁵

A simple example. You filed single for 2025 with $16,500 in itemized deductions, $5,000 of which was state income tax. The 2025 single standard deduction was $15,000, so itemizing beat it by $1,500. If a $2,000 state refund arrives in 2026, only $1,500 of it is taxable. That $1,500 is the actual federal tax benefit you got from itemizing; the other $500 produced no benefit and comes back tax-free. Publication 525 has a worksheet that walks through the math.¹

You Itemized but Picked the Sales Tax Deduction

On Schedule A you can deduct either state income taxes or state sales taxes, not both. If you chose sales tax, your state income tax payments produced no federal benefit, and a refund of those income taxes is not taxable.²

Your State Taxes Exceeded the SALT Cap

The state and local tax deduction is capped. For 2026 the cap is $40,400 in combined state and local income, sales, and property taxes, half that for married filing separately.⁶ Anything you paid above the cap never reduced your federal tax, so a refund of that slice is not taxable. If your state taxes were well over the cap, most or all of the refund can be tax-free even though you itemized.

Property Tax Rebates

Property tax refunds and state rebate programs follow the same rule. If you itemized and deducted the property taxes, a later rebate is income to the extent it produced a federal tax benefit. If you took the standard deduction that year, the rebate is not taxable.⁵ A rebate received in the same year you paid the tax is handled by reducing that year’s deduction rather than reporting income the following year.

Interest on a Late Refund Is Always Taxable

Even a completely tax-free refund can carry a taxable piece: the interest the IRS pays when a refund is late. The IRS is required to add interest on refunds not issued within 45 days of the return’s due date or filing date, whichever is later.⁷ The rate is set quarterly; for mid-2026 it is 7%.⁸

This interest is treated the same as bank interest. Report it on the interest income line of Form 1040 for the year you receive it.⁹ If the interest is $10 or more, the IRS sends a Form 1099-INT in January.¹⁰ Under $10, no form is issued, but the tax still applies. It is easy to miss because the interest often lands in the same direct deposit as the refund.

How to Report a Taxable Refund

A taxable state or local refund goes on Schedule 1 of Form 1040, Line 1, under additional income.¹¹ Refund interest goes on the interest income line of Form 1040. The state agency reports the refund to you and the IRS on Form 1099-G, usually by late January and often through the agency’s online portal rather than by mail.¹²

A 1099-G shows the gross refund, not the taxable amount. Run through the tax benefit calculation before entering anything on your return. If you took the standard deduction the year the taxes were paid, the taxable amount is zero regardless of what the 1099-G reports.³ Many filers who did not itemize report the whole amount by mistake and overpay.

If You Already Filed and Left a Taxable Refund Off

You can fix it with Form 1040-X, which can now be filed electronically.¹³ Correcting on your own is worth doing because the IRS receives every 1099-G and its automated matching program flags returns that leave one out. If the underreporting is treated as negligent, the accuracy-related penalty is 20% of the underpayment.¹⁴
