Tax Offset Phone Number: The Right Line, Disputes, and Notices

The tax offset phone number is 800-304-3107, the automated line for the Treasury Offset Program (TOP) run by the Bureau of the Fiscal Service. Call it when your federal refund has been reduced or taken to pay a past-due debt, and the system will tell you which agency requested the offset and how to reach them. Hours are Monday through Friday, 7:30 a.m. to 5:00 p.m. Central time.¹ Callers who are deaf, hard of hearing, or have a speech disability can reach a Communications Assistant through the Federal Relay Service at 800-877-8339.²

What the Automated Line Can Do

800-304-3107 is an Interactive Voice Response system, not a staffed help desk. It can identify which agency submitted your debt to TOP, give you that agency’s contact information, and share information about debts referred to TOP and payments that have been offset.³

What it cannot do is resolve anything. Fiscal Service cannot negotiate a payment plan, change the offset amount, reverse the offset, or issue a refund. Its role is to collect the money and pass it to the agency you owe.² Every real fix happens somewhere else.

Which Number You Actually Need

The right phone number depends on what you’re trying to accomplish.

To find out who took your refund: call 800-304-3107. You should also receive a written notice from Fiscal Service showing the original refund amount, the offset amount, and the receiving agency’s name, address, and phone number. If you didn’t get the notice, the IVR line gives you the same information.¹

To dispute the debt, arrange a payment plan, or ask about reducing the offset: call the creditor agency identified on your notice or through the IVR line. Fiscal Service has no authority to change any of these things.²

To question the IRS side of the math: contact the IRS only if the original refund amount shown on the Fiscal Service notice doesn’t match the refund shown on your tax return.¹ Anything about the debt itself belongs with the creditor agency.

To try to stop an offset because of hardship (federal tax debt only): call the IRS at 800-829-1040 as soon as you file your return.⁴

Getting Your Share Back If the Debt Isn’t Yours

When you filed a joint return and only your spouse owes the debt, you can recover your portion of the refund by filing IRS Form 8379, Injured Spouse Allocation.⁵ You qualify if you reported income on the joint return (or claimed a refundable credit like the Earned Income Credit), you made tax payments through withholding or estimated payments, and you are not personally liable for the debt that caused the offset.⁶ If the debt is a joint obligation, Form 8379 won’t help.

File Form 8379 with your joint return, or send it separately to the IRS service center where you filed the return once you learn of the offset.⁵ Processing runs about 8 weeks when filed on its own after the return is processed, about 11 weeks when e-filed with the return, and about 14 weeks when mailed on paper with the return.⁷

Community property states apply their own allocation rules. In most of them, 50% of a joint overpayment (excluding the Earned Income Credit) can be applied to a nontax debt, and the Earned Income Credit is allocated based on each spouse’s individual earned income.⁸

Don’t confuse this with innocent spouse relief. Form 8379 recovers your share of a refund taken for your spouse’s debt. Form 8857 is the different form used when the IRS says you owe additional tax because of something your spouse did on a joint return.⁶ Filing the wrong one is a common mistake.

Stopping an Offset Before It Happens

Once your refund has been applied to the debt, options narrow sharply. Acting before the offset gives you more room.

If the debt is a federal tax debt and losing the refund would leave you unable to cover essentials like rent, utilities, or medical care, you may qualify for an Offset Bypass Refund (OBR). The IRS can release part of your refund to relieve immediate hardship instead of applying it to the tax balance. Two limits matter: OBRs apply only to federal tax debts, not to child support, student loans, or other nontax debts collected through TOP, and you must request the OBR before the offset takes place.⁴

To request one, file your return on time, call 800-829-1040 as soon as possible after filing, and be ready with documentation of the hardship: eviction notices, utility shutoff warnings, medical bills. The Taxpayer Advocate Service can also help. File Form 911 with a copy of your return and your hardship documentation, then call your local TAS office to confirm they received it.⁴

For nontax debts, the OBR isn’t available, but a parallel option exists. If the creditor agency certifies that the full offset would cause financial hardship, the agency can direct Fiscal Service to offset a lesser amount based on your financial circumstances.⁹ You have to reach the agency before tax season and make the case there.

Federal regulations also require the creditor agency to offer you a written repayment agreement before referring the debt to TOP.¹⁰ If you know you have an outstanding federal or state debt and a refund is coming, calling the agency to set up repayment is usually the cleanest way to protect the refund.

Disputing the Debt Itself

Disputes go to the creditor agency, not to Fiscal Service and not to the IRS. Call the agency on your offset notice or the one identified through 800-304-3107 and ask for their formal dispute process. Most require a written request.

Your written dispute should include your full name, Social Security number, the offset date and amount, and any reference number the agency uses. Attach anything that supports your position: cancelled checks, payment receipts, payoff confirmations, court orders showing the debt was satisfied, or documents showing the debt isn’t yours.

Documentation varies by debt type:

Federal student loans: proof of consolidation, rehabilitation, discharge, or current repayment status that should have prevented referral to TOP.
State tax debts: copies of filed state returns or official notices showing a zero balance.
Child support: court orders modifying or terminating the obligation, or payment records from the state disbursement unit.

If the agency agrees the offset was wrong, it initiates the refund back to you. Fiscal Service cannot reverse an offset on its own; the correction has to come from the agency that certified the debt.² Keep copies of everything and follow up if you haven’t heard back in 30 days.

Your Right to a Pre-Offset Notice

You should have received a warning before any of this happened. The creditor agency is required to notify you at least 60 days before referring a debt for tax refund offset. The notice must explain what the debt is for, how much you owe, the agency’s intent to collect from a federal payment, and how to dispute the debt or present evidence that all or part of it is not past-due or not legally enforceable.¹¹ It must also explain your right to review the agency’s records on the debt and your right to enter into a written repayment agreement.³

If you never received that letter, say so when you contact the creditor agency. It’s a potential basis for challenging the offset.
