Every person, firm or corporation who has operating assets conducting business within the City of Sun Prairie must file a Statement of Personal Property with the City Assessor's Office each year on or before March 1st.
Important Note...due to technical difficulties the City of Sun Prairie has discontinued our Personal Property Online System. All future Personal Property Statements are to be filed manually. A Statement of Personal Property form is expected to be mailed to businesses by the first of the week.
If you are a new business located within the City of Sun Prairie please complete the New Business Form. The Assessor's Department will start a new Personal Property account for you.
Businesses that fail to file a Statement of Personal Property are subject to penalty and forfeit their right to appear before the Board of Review to contest their assessment. Completed Statement of Personal Property forms are confidential and are not available for public inspection.
