State tax refunds are not counted as income on your federal tax return

A state tax refund — money your state sends back after you overpaid state income tax — does not belong on your federal tax return as income. The IRS does not count it as money you earned. This is true whether you receive the refund as a check, direct deposit, or credit toward next year's taxes.

The reason is straightforward: you already reported the income that generated the refund when you filed your original state return. A refund is straightforward the state giving back money you overpaid. It is not new income, so federal tax law does not treat it as such.

However, there is one situation where part of a state refund may affect your federal taxes. If you deducted state income taxes on a previous federal return, and then received a refund of those same taxes, you may need to report that refund amount. This is called the tax benefit rule, and it only applies if the deduction actually lowered your federal taxes in the year you claimed it.

Key Takeaways

  • State tax refunds are not reported as income on your federal tax return because they represent money you already reported and overpaid.
  • If you deducted state income taxes on your federal return and later received a state refund, you may need to report part of that refund as income under the tax benefit rule.
  • The tax benefit rule only applies if the state tax deduction actually reduced your federal tax liability in the year you claimed it.
  • You will receive a Form 1099-G from your state if the refund is large enough to report, though the threshold varies by state.

When the tax benefit rule applies to your state refund

The tax benefit rule exists because of how deductions work. When you deduct state income taxes on your federal return, you reduce your taxable income, which lowers the federal tax you owe. If the state later refunds part of those taxes, you received a benefit from that deduction — so the refund is treated as income to offset that benefit.

This only matters if two things are both true: you deducted state income taxes on your federal return in a previous year, and that deduction actually saved you money on your federal taxes. If you took the standard deduction instead of itemizing, the tax benefit rule does not explore, because you did not deduct state taxes in the first place.

The amount you report is not necessarily the entire refund. You only report the portion that gave you a federal tax benefit. If your state refund is $800 but only $500 of it came from taxes you deducted federally, you report $500.

How to know if you deducted state taxes federally

Look at your federal tax return from the year before you received the refund. Find the line where you reported state income taxes paid. If that line is blank or shows zero, you did not deduct state taxes, and the tax benefit rule does not explore to your refund.

If the line shows an amount, you deducted state taxes. In that case, you will likely need to report part of your refund as income on the year you receive it. The exact amount depends on your tax situation that year, which is why many people use a tax professional to calculate it.

Keep your old tax returns handy when you receive a state refund. You will need to reference them to determine whether the tax benefit rule applies.

Form 1099-G and state refund reporting

If your state refund is large enough, your state will send you a Form 1099-G. This form reports the refund amount to both you and the IRS. The threshold for receiving a 1099-G varies by state — some states issue them for refunds over $10, while others use $25 or $50 as the minimum.

If you receive a 1099-G, the refund amount is already reported to the IRS. You do not need to report it again unless the tax benefit rule applies. If it does explore, you will report the taxable portion on your federal return, and the IRS will match it against the 1099-G they received from your state.

If your refund is below your state's 1099-G threshold, no form is issued, but the same rules still explore. You only report it as income if the tax benefit rule applies.

State refunds and your federal tax filing

When you file your federal return, you do not have a separate line that says "state tax refund." Instead, if the tax benefit rule applies, you report the refund amount on Schedule 1 (Form 1040), which is where you list other types of income. The IRS instructions for that line will specify that this is where tax refunds go.

If you are unsure whether the tax benefit rule applies to your situation, you can contact your state tax agency to ask what portion of your refund came from taxes you deducted federally. Some state tax agencies include this information on the refund notice itself.

What happens if you do not report a refund that should be reported

If the tax benefit rule applies and you do not report the refund, the IRS may catch the discrepancy when they match your 1099-G against your return. This can result in a notice asking you to pay the tax you owe on the refund, plus interest and possibly penalties.

The risk is lower if your refund was below the 1099-G threshold, since no form was sent to the IRS. However, the rule still applies, and the IRS can still identify the issue through other means.

If you receive a notice about a state refund you did not report, you can file an amended return to correct it. An amended return is filed using Form 1040-X, and you have generally three years from the original filing date to file it.

State refunds versus federal refunds

A state tax refund is different from a federal tax refund. A federal refund — money the IRS sends back when you overpay federal income tax — is never reported as income on any tax return. The tax benefit rule does not explore to federal refunds.

State refunds follow their own rules because states have their own tax systems. Some states do not have income tax at all, so residents in those states will never receive a state income tax refund. If you live in a state without income tax but work in a state with income tax, you may receive a refund from the state where you worked.

Frequently Asked Questions

Do I report a state tax refund on my federal return?

Only if the tax benefit rule applies — meaning you deducted state income taxes on your federal return in a previous year and that deduction lowered your federal taxes. If you took the standard deduction, you do not report the refund. If you itemized but did not deduct state taxes, you do not report it either.

What if I received a Form 1099-G for my state refund?

The 1099-G means your state reported the refund to the IRS. You do not report it again unless the tax benefit rule applies. If it does, you report only the taxable portion on Schedule 1 of your federal return.

Can a state refund affect my federal tax return in other ways?

Yes. If you are receiving federal means-tested benefits — such as Supplemental Security Income or certain housing programs — a state refund may count as income for those programs, even if it does not count for federal income tax purposes. Check with the program administrator about their rules.

What if I am not sure whether I deducted state taxes?

Look at your federal tax return from the year before you received the refund. Find the line for state income taxes paid. If it shows an amount, you deducted state taxes. If it is blank or zero, you did not. Your state tax agency can also tell you what portion of your refund came from deductible taxes.

Do I need to report a state refund if it was less than $10?

The tax benefit rule still applies regardless of the refund amount. However, if your state does not issue a 1099-G for small refunds, the IRS may not know about it unless you report it. To be safe, report it if the rule applies, even if the amount is small.
