How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

Frequently asked questions

What is the property tax rate in Ozaukee County, WI?

How much are property taxes on a median home?
On the median home ($390,200), the estimated annual bill is about $4,631.
Is Ozaukee County's rate high or low?

How does the effective rate differ from my mill rate?

Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Ozaukee County assessor within the local deadline, typically with comparable sales as evidence.
