Your refund may have been denied in full or in part for the following reasons: 

• You owe money from prior tax years so the refund you expected was put towards the taxes owed.
• Your refund may have expired.  Claims are only valid for four (4) years from when you originally paid taxes or the date your return was due, whichever is later. 
• There may be other reasons.  If you have questions or concerns about your refund, please call the Taxpayer Assistance department  at (313) 224-3315.
