Waukesha County lists contracted communities where first-installment payments are sent to the County Treasurer.
Local treasurer may collect first installment
For remaining communities, payments may need to be payable to and mailed to the local municipal treasurer.
Special timing note
County guidance says it does not receive City of Waukesha tax information until the first of the following year, so users may need the city treasurer directly for early details.
