Determining Property Taxes

Property taxes are determined early in December of each year based on the levies of 5 independent taxing units:

  • City of Waukesha
  • County of Waukesha
  • School District of Waukesha
  • State of Wisconsin
  • Waukesha County Technical College

Special Items

Special Assessments and Special Charges (if applicable) are added to the tax amount to create the amount due.


Administration of property tax bills and collection is according to Wisconsin State Statutes, Chapter 74 (PDF).

Collection Dates

The City Clerk/Treasurer's office collects current real estate taxes from mid-December to July 31. After July 31st, our real estate tax records are turned over to the Waukesha County Treasurer's Office. The County Treasurer collects all delinquent real estate taxes.
