State tax refunds are not taxable on your federal return if you did not deduct state taxes on your previous year's federal return
The rule is straightforward: you pay federal tax on a state refund only if you deducted state income tax (or state sales tax) on your federal return the year you paid that state tax. If you took the standard deduction instead of itemizing, your state refund is not taxable to the IRS. If you itemized but did not deduct state taxes, the refund is also not taxable.
This rule exists because the IRS does not want you to get a tax benefit twice—once when you deducted the state tax and again when you receive the refund. The refund is simply returning money you already paid; it should not create a second tax advantage.
The IRS calls this the tax benefit rule. It applies to state income tax refunds, city income tax refunds, and refunds from any other tax you deducted on your federal return. It does not apply to refunds of taxes you did not deduct.
Key Takeaways
- A state tax refund is not taxable on your federal return if you claimed the standard deduction in the year you paid that state tax.
- A state tax refund is taxable only if you itemized deductions and included state income tax (or state sales tax) on your federal return for the year you paid the state tax.
- The IRS uses Form 1040 Schedule 1 to report taxable state refunds; you will receive a Form 1099-G if the refund is over a certain threshold.
- If you itemized in one year but claimed the standard deduction in another, only the refund from the year you itemized is taxable.
- You do not report a non-taxable state refund on your federal return at all.
How the standard deduction affects whether your refund is taxable
If you claimed the standard deduction on your federal return for the tax year in which you paid the state tax, your state refund is not taxable. The standard deduction is a flat amount you subtract from your income without listing individual deductions. Because you did not deduct state taxes, the refund does not trigger the tax benefit rule.
For example: In 2023, you paid $4,000 in state income tax and claimed the standard deduction on your 2023 federal return. In 2024, you receive a $1,200 state refund. That $1,200 is not taxable on your 2024 federal return because you never deducted the state tax in the first place.
The standard deduction amount changes each year and depends on your filing status and age. For 2024, the standard deduction ranges from $14,600 (single filers) to $29,200 (married filing jointly). Most taxpayers use the standard deduction because it is simpler and often larger than their itemized deductions would be.
When itemizing deductions makes your state refund taxable
If you itemized deductions on your federal return and included state income tax (or state sales tax) as one of your deductions, any state refund you receive is taxable on your federal return. This is the core of the tax benefit rule: you received a federal tax benefit by deducting the state tax, so the refund is taxable income.
Itemizing means you listed specific deductions—mortgage interest, charitable donations, state and local taxes, medical expenses—instead of taking the standard deduction. You do this only if your total itemized deductions exceed the standard deduction for your filing status.
The state and local tax (SALT) deduction is capped at $10,000 per year on your federal return. If you paid $15,000 in state income tax but itemized, you could only deduct $10,000 of it. The full refund you receive later is still taxable, even though you could not deduct all of the tax you paid.
How to know if you itemized in the year you paid the state tax
Look at your federal tax return (Form 1040) for the year you paid the state tax that generated the refund. On Schedule A, you will see either your itemized deductions or a note that you claimed the standard deduction. If Schedule A shows itemized deductions and includes a line for state and local taxes, you itemized.
If you filed jointly with a spouse, both of you used the same method—either both itemized or both claimed the standard deduction. A refund based on taxes paid during that year is taxable to both of you proportionally, unless your return shows otherwise.
If you no longer have your old return, you can request a transcript from the IRS. Call 1-800-908-9946 or visit irs.gov and select "Get Your Tax Record." The IRS will send you a copy showing whether you itemized and what you deducted.
Reporting 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). You will also receive a Form 1099-G from your state if the refund is $10 or more. The 1099-G shows the refund amount in Box 1 (State income tax refund).
Enter the amount from Box 1 of the 1099-G on Schedule 1, line 1. If you received refunds from multiple states, add them together and enter the total. You do not need to attach the 1099-G to your return, but keep it for your records.
The IRS matches the 1099-G it receives from your state against your return. If you do not report a taxable refund that the state reported, the IRS will likely send you a notice asking for the missing income.
What to do if your refund is not taxable
If your state refund is not taxable—because you claimed the standard deduction or did not deduct state taxes—you do not report it on your federal return at all. You may still receive a Form 1099-G from your state showing the refund amount, but you ignore it for federal tax purposes.
Some states issue a 1099-G for all refunds over a certain amount, regardless of whether the refund is taxable federally. This is normal. The 1099-G is informational; it does not mean you must report the refund to the IRS.
Keep the 1099-G with your tax records anyway. If the IRS ever questions why you did not report a refund shown on a 1099-G, you can explain that you claimed the standard deduction and therefore the refund was not taxable under the tax benefit rule.
State refunds versus federal tax refunds
A state tax refund is different from a federal tax refund. A federal refund is money the IRS overpaid you during the year (through withholding or estimated tax payments). Federal refunds are never taxable because they are your own money being returned to you.
A state refund works the same way—it is your own money being returned—but the IRS taxes it if you deducted the original state tax. This is a quirk of federal tax law: the IRS wants to prevent you from getting a deduction and a refund for the same dollar.
If you received a federal refund and a state refund in the same year, they are taxed separately. The federal refund is not taxable. The state refund is taxable only if you itemized and deducted state taxes.
Frequently Asked Questions
If I claimed the standard deduction last year, do I have to report my state refund this year?
No. If you claimed the standard deduction in the year you paid the state tax, the refund is not taxable and you do not report it on your federal return. You may receive a Form 1099-G from your state, but you do not need to act on it for federal purposes.
What if I itemized in 2023 but claimed the standard deduction in 2024?
Only the refund from state taxes you paid in 2023 (and deducted on your 2023 return) is taxable on your 2024 return. If you paid state taxes in 2024 and claimed the standard deduction on your 2024 return, any refund from 2024 taxes is not taxable. The year you paid the tax is what matters.
I paid $15,000 in state tax but could only deduct $10,000 because of the SALT cap. Is my whole refund taxable?
Yes. Even though you could only deduct $10,000 on your federal return, the entire refund is taxable because you did deduct state taxes. The SALT cap limits your deduction but does not change whether the refund is taxable.
Do I need to keep my Form 1099-G if the refund is not taxable?
Yes. Keep it with your tax records for at least three years. If the IRS questions why you did not report a refund shown on a 1099-G, you can use your return and the 1099-G to show that you claimed the standard deduction and therefore the refund was not taxable.
What if I am not sure whether I itemized or claimed the standard deduction?
Request a transcript of your return from the IRS by calling 1-800-908-9946 or visiting irs.gov. The transcript will show exactly which method you used and what you deducted. This takes about two weeks by mail or is available immediately online.
