Can the IRS Keep Your Tax Refund? Refund Offsets Explained

Two kinds of refund offset, and how to tell which one you had

A refund can shrink for three reasons: the IRS corrected your return, the IRS applied it to federal tax you owe, or Treasury used it to pay another agency. The IRS calls the last two offsets. IRC 6402(a) lets the IRS credit an overpayment against any federal tax you owe and refund the rest; subsections (c) to (f) require offsets for past-due child support, federal agency claims, state income tax and covered unemployment compensation.

Treasury’s Bureau of the Fiscal Service issues IRS refunds and runs the Treasury Offset Program (TOP). The IRS says the details of a non-tax offset “aren’t provided to the IRS”, so call the IRS about one only if the refund on the offset notice differs from the refund on your return. If you got no notice at all, the Taxpayer Advocate Service suggests calling the IRS at 800-829-1040 (IRS.gov, 2026) to find out where the money went.

When the IRS keeps your refund for back taxes: the CP49 notice

The IRS sends a CP49 when “we used all or part of your refund to pay a tax debt.” It explains how the refund was applied and whether a balance remains. The offset counts as a payment, so interest and the failure-to-pay penalty stop on the part it covered. If anything is left after the balance is paid, the IRS says you’ll get it within 3 weeks unless you owe other taxes or debts it is required to collect.

What to do next depends on what remains:

• Balance paid in full. Nothing more to do; keep the notice with that year’s records.
• Balance still owed. Pay it, or set up a plan. Our relief by balance size guide shows which plans fit. The IRS lists the same options on the CP49 page: a payment plan, an offer in compromise or a temporary collection delay.
• You think the balance is wrong. Call the number on the notice with your return or amended return ready. Our guide to disputing an IRS balance covers each route.

If you already had a bill for that year, such as a CP14 or a CP501 reminder, the offset applied your refund to that same balance. Check the year and amount against those notices.

When another agency takes your refund: the Treasury Offset Program

The Treasury Offset Program matches federal payments, including tax refunds, against a database of past-due obligations that federal and state agencies have referred to it. Before referring one, the agency must send you a letter explaining what it is for, how much you owe, that it intends to collect from federal payments, and your rights to review the claim and arrange repayment. When TOP takes money, you get a notice showing the original refund, the amount taken and the agency that received it.

• Disputes go to the agency. Under IRC 6402(g), neither the IRS nor a federal court can review these offsets as a tax matter; your rights are against the agency or state that received the money. TOP staff cannot discuss the obligation or refund what was taken.
• Payment goes to the agency. TOP cannot accept payments. To prevent future offsets, contact the agency or its collection program and pay or resolve the claim.
• Delays are normal. Treasury says there can be a lag of two weeks or more before the receiving agency records the money.

If you don’t know which agency was paid, the TOP automated line is 800-304-3107 (TTY 800-877-8339), per the IRS and Treasury pages cited below.

Refunds during a payment plan, hardship status or an offer in compromise

Being in an agreement with the IRS does not protect your refund. Each option has its own rule:

A refund taken during a plan is a payment toward the balance, not a substitute for the next installment. Missing a payment because a refund was applied can put the plan in default. For plan rules see IRS payment plans compared, and for offer terms in detail, the Fresh Start offer in compromise guide.

Can you get an offset refund back?

Hardship: ask before the refund is applied

If you cannot pay basic living expenses, the IRS can issue an Offset Bypass Refund, a refund that skips your federal tax balance (IRM 21.4.6.5.7.1). Hardship means economic hardship as defined under IRC 6343, decided case by case, and you need documents showing the hardship and the amount you need. Timing is strict: the request generally must be processed before the return that creates the refund is assessed, and once the offset has posted the IRS generally cannot undo it. The IRS cannot bypass a Treasury Offset Program offset for child support or another agency’s claim; only that agency can grant a hardship request. Call the IRS as soon as you file, and if it cannot act in time, ask the Taxpayer Advocate Service for help on Form 911 (Rev. 6-2026 (IRS.gov, 6-2026)) or at 877-777-4778 (IRS.gov, 2026).

Joint return: injured spouse allocation

If you filed jointly and the refund paid your spouse’s past-due obligation that you are not responsible for, file Form 8379, Injured Spouse Allocation, to get your share. That covers child support, federal agency claims, state income tax and unemployment compensation, and the IRS CP49 page says it also applies when the refund paid taxes only your spouse owes. File it with the return or after the offset notice, a separate form for each year, within 3 years of filing the return or 2 years of paying the tax, whichever is later. The IRS says processing can take up to 8 weeks when filed alone, longer with a return. Our divorce and joint tax bills guide explains how this differs from innocent spouse relief.

Joint tax balance you shouldn’t owe

If the refund paid a joint federal tax balance and you believe only your spouse or former spouse should be responsible, Form 8379 is the wrong form. TAS points to Form 8857, Request for Innocent Spouse Relief; see innocent spouse relief.

How to stop future refund offsets

1. Find out what you owe. Check every year’s balance in your IRS Online Account; our guide to finding your IRS balance walks through it.
2. Pay off or resolve the balance. Federal tax offsets stop when the balance is paid. A plan alone does not stop them.
3. Resolve non-tax claims with the agency. Child support, student loan and state claims stay in TOP until the agency removes them.
4. Consider your withholding. If you expect refunds to be taken, the IRS Tax Withholding Estimator can help you set withholding closer to what you owe, so less money sits with the IRS. Pay the balance directly instead.
5. Keep filing. An offset is not a reason to skip a return; unfiled years add the failure-to-file penalty.

You can do all of this yourself, and free help is available from TAS and Low Income Taxpayer Clinics. Not sure what your notice means? Get a free review or call 1-877-800-8180. To see what a consultation covers, read what happens in a free consultation.
