Most refunds are not taxable, but some are—and the difference depends on what you got the money back for

A refund is taxable only if the original payment reduced your taxable income in the first place. If you paid for something with after-tax dollars and got your money back, there is nothing to report. If you deducted the expense on your tax return and later received a refund for it, that refund becomes taxable income in the year you receive it. The IRS calls this the tax benefit rule: you cannot deduct something and then get it back tax-free.

The most common scenario is a state or local tax refund. If you itemized deductions on your federal return and deducted state income tax or property tax, a refund of that tax is taxable federally in the year you receive it. If you took the standard deduction instead, the refund is not taxable. Medical expense refunds, business expense refunds, and casualty loss refunds follow the same logic: taxable only if you deducted them.

Key Takeaways

  • A refund is taxable only if the original expense was deducted on your tax return and gave you a tax benefit.
  • State and local tax refunds are taxable federally if you itemized deductions; they are not taxable if you took the standard deduction.
  • Refunds for medical expenses, business expenses, or casualty losses are taxable only if you deducted them in a prior year.
  • The IRS will send you a Form 1099-G if a state tax refund exceeds $10, and you must report it on your federal return.
  • Refunds from purchases, returns, or overpayments on non-deductible items are never taxable.

State and local tax refunds: the most common taxable refund

When you file your federal return, you can either take the standard deduction or itemize deductions. If you itemized and deducted state income tax, local income tax, or property tax, any refund you receive from the state or locality is taxable income on your federal return in the year you get it.

The amount varies by state and by your tax situation. Some states refund overpaid income tax; others refund property tax credits or sales tax. The rule is the same for all of them: if you deducted it federally, the refund is taxable federally.

If you took the standard deduction instead of itemizing, you did not deduct any state or local taxes, so the refund is not taxable. The IRS will still send you a Form 1099-G if the refund is $10 or more, but you do not have to report it on your federal return.

You will receive the Form 1099-G from your state tax authority, usually by January 31 of the year after you receive the refund. The form shows the refund amount in Box 1a. Report this on Schedule 1 (Form 1040), line 1, as "other income."

Refunds for deducted medical and business expenses

If you deducted medical expenses on Schedule A and later received a refund—for example, a reimbursement from an insurance company or a correction from a provider—that refund is taxable in the year you receive it, but only to the extent it reduced your taxes in the year you deducted it.

The same applies to business expenses. If you deducted a business expense on Schedule C and the vendor later refunded part of the cost, the refund is taxable income. You report it on the same line where you originally deducted the expense.

This rule prevents you from getting a tax benefit twice: once when you deducted the expense, and again by keeping the refund tax-free.

Casualty loss refunds and insurance settlements

If you deducted a casualty loss (damage from fire, theft, or disaster) on Schedule A and later received an insurance settlement or other reimbursement, the refund is taxable to the extent it exceeds your basis in the property. In most cases, this means the refund is fully taxable because you already deducted the loss.

The exception is if the refund is less than the loss you deducted. In that case, you may need to file an amended return to adjust your deduction. This is a complex situation; consider consulting a tax professional if you are in this position.

Refunds that are never taxable

Refunds for purchases you made with after-tax money are never taxable. This includes:

  • Returns of merchandise or services you bought for personal use
  • Refunds from overpaying a bill or invoice
  • Rebates on consumer goods
  • Refunds of deposits (security deposits, rental deposits, etc.)
  • Refunds of tuition or fees you did not deduct

The key is that you did not deduct these expenses on your tax return. You paid for them with money you had already paid taxes on, so a refund straightforward returns your own money to you.

How to report a taxable refund on your return

If you receive a Form 1099-G for a state or local tax refund, report it on Schedule 1 (Form 1040), line 1. Write "State tax refund" and the amount.

For other refunds—medical, business, or casualty—report them on the same schedule or form where you originally deducted the expense. If you deducted a medical expense on Schedule A, report the refund there. If you deducted a business expense on Schedule C, report the refund on Schedule C.

Keep the documentation showing the refund: the Form 1099-G, a bank statement showing the deposit, or a letter from the provider. The IRS may ask to see it if you are audited.

What happens if you do not report a taxable refund

If you receive a Form 1099-G and do not report it, the IRS will likely catch it. The IRS receives a copy of every 1099-G issued, and their matching system flags returns that do not report the income shown on the form.

If you fail to report it, you may owe back taxes, penalties, and interest. The penalty for not reporting income is typically 20 percent of the unpaid tax, plus interest calculated from the original due date. It is much simpler to report the refund when you file.

If you believe a refund should not be taxable—for example, because you took the standard deduction—you can still report it and attach a note explaining why it should not be taxed. The IRS may ask for documentation, but you have a legitimate reason to dispute it.

Frequently Asked Questions

Do I have to report a state tax refund if it is under $10?

No. The IRS does not require a Form 1099-G to be issued for refunds under $10, and you do not have to report it. However, if you itemized deductions and received a refund of any amount, it is technically taxable. Most people do not report refunds under $10, and the IRS does not pursue them.

I took the standard deduction, so my state tax refund is not taxable, right?

Correct. If you did not itemize deductions, you did not deduct state or local taxes, so the refund is not taxable federally. You may still receive a Form 1099-G, but you do not report it on your federal return. Some states may tax the refund, so check your state rules.

What if I received a refund but did not deduct the original expense?

Then the refund is not taxable. The tax benefit rule only applies if you deducted the expense and got a tax benefit from it. If you paid for something with after-tax dollars and got a refund, there is no tax consequence.

Can I claim a loss if my refund is less than what I deducted?

Possibly, but it is complicated. If you deducted a casualty loss and received a partial refund, you may need to file an amended return to adjust your deduction. This depends on your specific situation and the type of loss. A tax professional can help you determine whether you can claim an additional loss.

Do I need to report a refund if I already paid taxes on the original amount?

Only if you deducted the original expense. If you paid for something with after-tax money and got a refund, there is no tax consequence. If you deducted it and got a refund, the refund is taxable because you are reversing the deduction.
