How do I find out if you owe back taxes to the IRS?

If you mail the return, it sometimes takes EIGHT weeks to get your refund,

Even filing electronically does not guarantee a quick refund.

If you have not gotten your refund by mid-March, and you get no satisfaction from the Where's My Refund? Application on the IRS website, THEN call the IRS at 1-800-829-1040.

You can check in advance if you are flagged for offset or not by calling FMS Autoresponder line at 1-800-304-3107
