Quick overview

A refund offset means part or all of your federal tax refund was applied to an outstanding debt (commonly past‑due child support or federal student loans) through the Treasury Offset Program (TOP) or IRS administrative processes. The good news: many offsets can be challenged if you act quickly and present the right evidence.

Who to contact first

  1. Read the offset notice carefully — it identifies the referring agency and the amount withheld. The notice may come from the Bureau of the Fiscal Service or the IRS. (Treasury Offset Program: https://fiscal.treasury.gov/top/)
  2. If the offset was for child support, contact your state child support enforcement agency. (U.S. Administration for Children & Families: https://www.acf.hhs.gov/css)
  3. If the offset was for federal student loans, contact your loan servicer or Federal Student Aid at https://studentaid.gov/ and ask for account review or correction.
  4. If the offset was applied to a joint return and you believe your spouse’s debt caused it, file Form 8379 (Injured Spouse Allocation) with the IRS to claim your share. See the IRS Form 8379 page for filing instructions (IRS: https://www.irs.gov/forms-pubs/about-form-8379).

Step-by-step: How to challenge the offset

  1. Preserve and collect documentation
  • Copies of cancelled checks, bank statements, child support payment records, court orders, payoff letters, or loan payment history. Keep correspondence with your state or loan servicer.
  1. Contact the referring agency to request an investigation or correction
  • For child support, bring proof of payments to your state agency.
  • For student loans, ask your servicer or the Department of Education to correct errors and provide a written statement. If the debt was submitted in error, the agency should request Treasury to release the offset.
  1. File the right claim with the IRS or agency
  • Injured spouse: If a joint return was offset and you are not responsible for the debt, file Form 8379. You can file it with your original return or separately if you already received an offset notice. (FinHelp guide: filing Form 8379)
  • Direct dispute with creditor: For TOP collections, the referring federal or state agency usually handles disputes. Ask that agency what documentation it needs to reverse the referral.
  1. Follow up and escalate if needed
  • Keep a record of names, dates, and case numbers. If the agency does not fix the error, file complaints with CFPB (https://www.consumerfinance.gov/) or contact your state’s attorney general or child support ombudsperson.

Forms, timelines, and realistic expectations

  • Form 8379 (injured spouse) instructions: https://www.irs.gov/forms-pubs/about-form-8379. Processing times vary; expect several weeks to a few months depending on IRS workload.
  • Treasury Offset Program referrals and releases can also take weeks after the creditor approves a correction. There is no single universal deadline for every dispute, so start immediately after receiving the offset notice.

Common mistakes to avoid

  • Waiting too long to act; delays slow resolution.
  • Not keeping proof of payments or court orders.
  • Contacting the IRS first when the referral came from a state child support agency — the state must correct its records and request Treasury to reverse the offset.

Practical tips from practice

  • Organize a single packet with certified payment histories, court documentation, and a clear cover letter outlining the error.
  • If your return was filed jointly, consider filing Form 8379 even if you are also contacting the creditor — the IRS can allocate your portion sooner while the agency corrects the referral. See our step‑by‑step guide to filing Form 8379: Filing Form 8379.

When to get professional help

If the offset involves large sums, unclear records, or a dispute the agency won’t correct, consult a tax attorney or an experienced tax professional. In my practice I’ve seen cases resolved more quickly when an advocate compiled the documentation and negotiated directly with the referral agency.

Example scenario (brief)

A client’s refund was offset for an alleged defaulted federal loan. We obtained payoff confirmation from the servicer and its written error acknowledgement. The servicer asked Treasury to release the offset; within weeks the client’s refund was returned. Keep a paper trail — it’s often decisive.
