Tax Bill Due Dates
Tax bills will be mailed to property owners by the 3rd Monday in December. As soon as the bills are printed they will be posted online for you to access.
Real Estate Taxes
The City of South Milwaukee offers two options for payment of your real estate taxes:
Option 1 - Full Payment Option
Full payment of the real estate taxes plus special assessments, special charges and delinquent utility amounts, if any, are due on or before January 31.
Option 2 - Installment Option (Refer to Tax Bill)
Please Note: Reminder notices are NOT mailed - the tax bill is the only bill you will receive. Mark your calendar with the tax installment due dates:
- First Installment - January 31
- Second Installment - April 30
- Third (Final) Installment - July 31
The installment amounts are printed on the tax bill. Each installment amount must be paid on or before its required due date. Special charges, special assessments, and delinquent utility amounts are not eligible for the installment plan and are due January 31.
If January 31, April 30, or July 31 falls on a Saturday or Sunday, payment will be considered timely if made on the following business day.
Personal Property Taxes
Personal property taxes (taxes for a business) are due on or before January 31.
Interest Charged on Delinquent Taxes
The first time that an installment due date is missed or an installment amount is underpaid, the tax bill becomes delinquent and the installment option is forfeited. All delinquent taxes require an interest and penalty payment of 1.5% per month (fraction of a month counts as a whole month) on the total unpaid balance of the tax bill retroactive to February 1 until paid.
Delinquent real estate taxes are collected by the City of South Milwaukee for the current tax year through July 31. After July 31, delinquent real estate taxes must be paid to:
