How Property Taxes Work in Wisconsin
In Wisconsin, property taxes fund essential local public services such as public schools, emergency services, county roads, and local health programs. Taxes are administered at the county level and calculated using local valuations and tax rates.
Assessment
Your county tax assessor determines the fair market value of your property. The taxable assessed value is calculated as a percentage of this market value, minus any exemptions.
Local Tax Rate / Millage
Local tax districts (counties, cities, and school systems) set millage rates annually. One mill is equal to $1 of tax per $1,000 of assessed property valuation.
Final Bill & Exemptions
Your final bill is calculated by applying the combined local tax rates to your taxable assessed value after subtracting any qualified exemptions.
Example Calculation for Wisconsin
For a home valued at $300,000 in Wisconsin, the annual property tax bill is approximately $3,579, based on the average effective rate of 1.19%. Your actual bill will vary based on your local county and city rates. Use our tax calculator to compute your estimate with local county rates.
Estimated State Tax Bills by Home Value
Calculated using the weighted state average effective rate of 1.19%.
| Assessed Home Value | Estimated Annual Tax | Estimated Monthly Escrow |
|---|---|---|
| $150,000 | $1,790 | $149.1 |
| $250,000 | $2,983 | $248.6 |
| $350,000 | $4,176 | $348.0 |
| $500,000 | $5,965 | $497.1 |
| $750,000 | $8,948 | $745.7 |
State Data Sourcing & Methodology
