File Personal Property Statement Online
Hint: It is helpful to have your 2016 postcard available for reference before filing. The Assessor's office mailed postcards to all businesses in the City of Sun Prairie at the end of December. If you are filing on behalf of a business, ask them to provide the postcard with the randomly assigned access PIN number.
