How refund offsets actually work

When you file a federal tax return, the IRS calculates your refund and compares your identity and refund amount against debt records in the Treasury Offset Program (TOP). Agencies that can request offsets include state child support agencies, the U.S. Department of Education (for defaulted federal student loans), and other federal or state agencies. If TOP finds a match, Treasury intercepts part or all of your refund and sends it to the creditor agency before you receive any money (Bureau of the Fiscal Service/Treasury; IRS).

Common debts that trigger an offset

  • Child support arrears (most common): States report past‑due child support to TOP.
  • Defaulted federal student loans: The Department of Education can request offsets for qualified defaults.
  • Federal non‑tax debts: Unpaid federal agency charges, some state income tax debts, and certain other federal obligations.
    (See Treasury’s description of the Treasury Offset Program and IRS guidance for details.)

What you will receive — and how to appeal

If your refund is offset, you will receive a written notice after the offset explaining: the amount taken, the agency that requested it, and contact information for that agency. To challenge the offset or request a refund:

  1. Review the notice carefully — it tells you which agency to contact.
  2. Contact the agency that requested the offset (for example, the state child support office or the Department of Education) to request a review or provide proof of payment or identity errors.
  3. If your offset was caused by a joint return and your portion was incorrectly taken, file Form 8379 (Injured Spouse Allocation) with the IRS to claim your share of the refund.
  4. If the offset appears to be an error by Treasury/IRS, follow the directions on the notice to request a review. Processing a successful dispute can take weeks to months.

Practical examples

  • Child support: A parent with a $4,000 refund who owes $3,500 in arrears will see $3,500 applied to child support and receive the remaining $500 (or none, if the debt equals or exceeds the refund).
  • Student loans: A taxpayer with a $2,500 refund and a defaulted federal student loan in TOP may have the full $2,500 offset to the loan balance.

How to avoid or limit future offsets

  • Monitor your accounts: Check your loan and child support balances regularly.
  • Injured spouse claim: On joint returns, file Form 8379 if your spouse’s debt is causing an offset to your refund. (IRS Form 8379)
  • Resolve or rehabilitate federal student loans: Loan rehabilitation or consolidation can remove the loan from offset eligibility once the loan is no longer in default. Contact the servicer or the Department of Education for options.
  • Set up payment plans: Work directly with the creditor agency to avoid referral to TOP.
  • Verify withholding and refunds: If you expect a refund and are near arrears, plan for cash flow so an offset doesn’t cause immediate hardship.

Professional tips from practice

In my experience helping clients, the two most effective immediate steps are (1) checking the post‑offset notice for the referring agency and (2) filing an injured‑spouse claim promptly on joint returns. For student‑loan cases, ask the loan servicer about rehabilitation options — that usually stops future offsets once the loan is brought current or rehabilitated.

Common mistakes to avoid

  • Waiting to dispute: Many people assume they’ll get prior notice — offsets often occur without warning.
  • Contacting the IRS first: The agency that requested the offset (listed on the notice) is usually the right place to start.
  • Missing Form 8379 deadlines: If you’re entitled to a share of a joint refund, file Form 8379 instead of waiting for the offset to be reversed.
