Your tax refund itself is not taxable income
No. The IRS does not tax your federal tax refund. A refund is money you overpaid to the government during the year — it belongs to you, and when it comes back, it is not treated as new income.
The money inside the refund was already subject to tax when you earned it. Your employer withheld it from your paycheck, or you paid it as estimated tax. The refund simply returns what you overpaid. The IRS does not tax you twice on the same dollar.
State tax refunds follow the same rule: your state does not tax the refund itself. However, some states have a wrinkle involving federal refunds, covered below.
Key Takeaways
- Federal tax refunds are not taxable income and do not appear on next year's tax return as earnings.
- State tax refunds are also not taxable by your state, but some states tax federal refunds as income under their own rules.
- Interest paid on a delayed refund is taxable income and must be reported on your next return.
- If you receive a refund by mistake or for a year you did not file, the IRS may reclaim it, but that reclamation is not a tax on the refund.
The federal refund exception: interest on delayed refunds
If the IRS owes you a refund and delays paying it beyond a certain point, they pay you interest. That interest is taxable income. You will receive a Form 1098-T or a notice showing the interest amount, and you must report it on your next tax return as interest income.
The threshold varies by year. In recent years, the IRS begins paying interest if a refund is delayed more than 45 days after the return's due date or the date you filed, whichever is later. The interest rate is set quarterly and is currently low, but it is still taxable.
This is rare for most filers. It happens most often when the IRS audits your return, requests additional information, or processes a return with errors that require correction.
State tax refunds and federal income
Most states do not tax your state refund. However, a handful of states — including Illinois, Indiana, Iowa, Missouri, Montana, New Mexico, and Ohio — tax federal tax refunds as income in the year you receive them. This is called the "tax benefit rule" or "recovery of a prior deduction."
The logic is this: if you deducted state taxes paid on your federal return (using the state and local tax deduction, or SALT), and then your state refunded part of those taxes, some states view the refund as a recovery of a deduction and tax it accordingly. You may owe state income tax on the refund amount.
If you live in one of these states and received a federal refund, check your state's tax instructions for the year you received it. You may need to report the refund amount on your state return. The amount is usually small, but it is not zero.
Refunds from other sources: business, insurance, and employer
Refunds from sources other than the tax system have different rules. A business refund, insurance refund, or employer refund may or may not be taxable depending on what it is and why you received it.
An insurance refund for overpaid premiums is generally not taxable. A refund from a business for a returned item is not taxable — it reduces the cost of what you bought. A refund of a security deposit is not taxable.
However, a refund of a prior deduction can be taxable. If you deducted a business expense in a prior year and received a refund for it in the current year, that refund may be taxable income. The same applies to refunds of medical expenses, charitable donations, or other deductions you claimed.
What happens if you receive a refund by mistake
If the IRS or your state sends you a refund you did not file for, or sends you more than you are owed, the money is not yours to keep. The government will reclaim it, usually by reducing a future refund or by sending a bill.
This is not a tax on the refund — it is a correction. However, if you spend the money and then have to repay it, you cannot deduct the repayment as a loss. You simply owe it back.
If you receive a refund for a year you did not file, do not cash the check. Contact the IRS or your state tax agency to report it. They will investigate whether someone filed a fraudulent return in your name.
Refunds and your next year's tax return
Your federal tax refund does not appear anywhere on your next year's tax return as income. It is not reported on a W-2, a 1099, or any other form. The IRS already knows about it — they sent it to you — and they do not expect you to report it again.
The only exception is interest paid on a delayed refund, which you must report as interest income on Schedule 1 of Form 1040.
If you received a state refund in a state that taxes federal refunds, you will report that on your state return for the year you received it, not on your federal return.
How to report interest income from a delayed refund
If you received interest on a delayed federal refund, the IRS will send you a notice showing the amount. Keep this notice with your tax records.
On your next tax return, report the interest amount on Schedule 1, Part I, line 8 (Other income). You do not need to attach the notice, but keep it in case you are audited.
The amount is usually under $100, but it must be reported even if it is small. Failing to report it can trigger a notice from the IRS, though the amount owed in additional tax is minimal.
Frequently Asked Questions
Can the IRS tax my refund if I owe back taxes or child support?
The IRS will not tax your refund, but they will offset it — meaning they will keep part or all of it to pay what you owe. This is called a refund offset or levy. It is not a tax; it is a collection action. You will receive a notice explaining what was offset and why.
Do I have to report my tax refund on my next year's return?
No. Your federal tax refund is not reported as income on your next return. The only exception is interest paid on a delayed refund, which you report as interest income on Schedule 1.
If I get a state refund, do I have to pay federal tax on it?
No. Your state refund is not taxable federal income. However, if you live in a state that taxes federal refunds, you may owe state tax on your federal refund — not the other way around.
What if I received a refund for a year I did not file?
Do not cash it. Contact the IRS or your state immediately. Someone may have filed a fraudulent return using your name and Social Security number. The agency will investigate and tell you what to do next.
Is a refund of overpaid estimated taxes taxable?
No. Estimated tax payments are money you paid to the government, and a refund of overpaid estimated taxes is not taxable income. It is a return of your own money.
