Property Tax Bill Availability & Collection

2025 property tax bills will be mailed by December 11, 2025.

Wauwatosa property tax balances will be available on the Milwaukee County Property Tax Public Portal. The portal is searchable by property address. In addition to balances, payment history, receipts and copies of original tax bills are all available electronically. Additionally, taxpayers are be able to make tax payments on the portal. 

In addition to web payments, taxpayers can also mail payments using the return envelope in the billing envelope or can drop off payments at the 24-hour secure payment depository at City Hall - however, they should enclose a payment coupon from the bill to include with payment. Paying in person at the Treasurer's Office at City Hall is also an option. 

Bills may be paid in full or the taxpayer may opt to make three installment payments due January 31, March 31, and May 31.

Treasurer’s Office hours are 8 am to 4:30 pm Monday through Friday.  The Treasurer’s Office is closed on city holidays.  See the insert enclosed in the tax bill mailing for specific hours of operation.

Property Revaluation in 2025

Wauwatosa performed a 2025 revaluation to bring our assessments more in line with current market value, to ensure the property tax burden is evenly distributed among taxpayers, and to comply with State law.

School District Referendums

On November 5, 2024, Wauwatosa voters passed two school district referendums. One referendum allows the school district to levy a property tax to fund facilities improvements. The other referendum funds operating costs for the district’s next four budget years. 

Here's what to know about the effects on property taxes:

• The 2025 tax bill will be the first year the 2024 referendums go into effect.
• Each tax bill will have a line item that shows the portion of the taxes attributed to the referendum. For each year the referendum is in effect, the taxpayer will know the exact dollar amount they are paying towards the referendum.
• There is a school facilities referendum from 2019 that is currently on the bill and is scheduled to end in 2039.
• More information can be found on the school district 2024 referendum webpage.
• If using the tax impact tool on the school referendum webpage, use the estimated fair market value from the 2024 tax bill.  This property value will be more in line with the 2025 market due to the planned citywide revaluation.
