To see if IRS is keeping your refund for student loans or other debt, call (800) 304-3107, for the US Treasury's Bureau of Fiscal Services.

For IRS debt, call the FMS at 1-800-304-3107 to find out if your refund was reduced because of an offset.

Call the IRS Taxpayer Advocate Service at 1-877-777-4778 (or visit www.irs.gov/advocate) if you feel your refund was reduced in error. The service is free.
