Assessment & Property Tax Information

The assessor is responsible for the valuation of all real and personal property located within the City of Oconomowoc for property tax purposes. It is our responsibility to provide fair and uniform assessments throughout the city. Assessment procedures are governed by Chapter 70 of the Wisconsin Statutes and the Wisconsin Property Assessment Manual. The city contracts with Grota Appraisals for assessment services.

Property tax bills are mailed annually in mid December following the annual budget process. Real estate property taxes can be paid in three installments due January 31, April 30, and July 31 of each year. Personal property taxes must be paid in full by January 31 of each year.
