Property Tax Collection

Property tax statements are typically mailed by the second full week in December.  The bills are mailed to the owner of record per the Milwaukee County Registrar of Deeds, unless an official mailing address change has been made at the City Assessor’s office prior to November 15.  If you do not receive a tax bill by December 15, the tax bill can be obtained using the city website (see below for further detail). 

Property Tax Web Portal: Online Tax Bills, Balances, Receipts / Make Online Tax Payments

Taxpayers can access their tax bill, balance and obtain their property tax payment receipt online.   The user will have the option of printing a tax bill or summary, the latter of which shows balance due and payments.  Additionally, the taxpayer can make a payment - the link to the payment site is found on the page where the tax information is found for the property.  User fees apply for all website payments. | Wauwatosa Property Tax Web Portal

Due dates / Installment Payments

Property tax payments are due January 31.  For those who pay their real estate property taxes using the three-installment plan, the first installment must be paid in full no later than January 31.  The second installment is due March 31 and the third, May 31.  There is no need to sign up for the installment plan; simply make the payments as scheduled on the tax bill.  Most personal property tax (business non-real estate) will be due by January 31.

Preparing the Payment

Checks should be made payable to “City of Wauwatosa”.  Submit your tax bill or tax summary with the payment.  For those that receive an escrow check from their mortgage company to be used towards payment of property taxes, please make sure to endorse the check. 

Where to Pay

By Mail:  The preferred method of payment is to mail your tax payment in the return envelope provided with your tax bill.  If the return envelope is lost, the payment can be mailed to our lockbox (preferred) at City of Wauwatosa, Bin 360, Milwaukee WI 53288-0360 or directly to our office at City of Wauwatosa, Treasurer's Office, 7725 W. North Ave., Wauwatosa WI 53213. Mail the entire tax bill and your check made payable to “City of Wauwatosa”.   Payments are receipted using the U.S. Postal Service postmark as the receipt date.

City Website:  Access the Wauwatosa Property Tax Web Portal and follow the instructions until property tax information is displayed for the property you wish to make a payment on.  Click on the payment link to make payment.  Please note that user fees will apply.

24 Hour Night Depository:  Payments can also be placed in the 24-hour depository located on the southwest end of city hall near the employee entrance.  A deposit made prior to midnight will be receipted using that day’s date.

In Person:  Payments can be made in person by cash or check during posted business hours.  Please bring tax bill so that receipt information can be validated directly onto the bill.  As a courtesy to your fellow taxpayers, please have checks prepared prior to appearing at the collection window.


The Treasurer’s Office is open Monday – Friday 8:00 am – 4:30 pm.  The office is closed City-observed holidays and weekends.  Some years, there are extended hours.  Announcements for the Treasurer’s Office Holiday schedule from year to year can be found in the event calendar of the City website, the winter edition of the city newsletter or the insert provided in the tax bill mailing.

Tax Payment Receipts

Receipts can be obtained by (1) utilizing the City website, (2) contacting the Treasurer's Office or (3) receiving validated receipt information on the tax bill at the time of payment in person.  Without a request, our office will only mail a receipt to those who still owe a balance as a reminder.

Failure to Pay Timely

For any property tax bill where payment is not made timely, the bill is considered delinquent and therefore the remaining balance is subject to 1% interest and 0.5% penalty charges per month, retroactive to February 1. A partial month is considered to be a full month.  (Wis. Stat. 74.12 & 74.47)
