Business & Floating Personal Property

Confidential Personal Property Returns are mailed to all business and floating property owners within Columbia County the beginning of January.  These forms are to be completed and mailed back to us by March 15.  If you do not receive a return, it is your responsibility to request or download a form, and to ensure it is filed timely.
