The Bureau of the Fiscal Service BFS, who issues IRS refunds, will send you a notice informing you of the reduction.If you do not receive the notice within two weeks contact the Bureau of the Fiscal Service BFS at 800-304-3107.Please read the following information related to your tax situation: Tax Topic 203, Refund Offsets for unpaid child support and certain federal, state, and unemployment compensation debtsWhat does that mean?  <response>: Im guessing it says what it means you have past child support or other debts due to the state yoy should call the number and get more info
