Assessed value
Property tax calculations generally begin with the taxable assessed value, which may differ from the sale price or estimated market value.

Select a planning preset or enter the effective property tax rate shown on a recent local tax bill for a more personalized estimate.
Effective tax rate
The effective rate represents annual property tax as a percentage of property value. Local rates can differ within the same county.
Credits and assessments
Tax credits may reduce the final bill, while special assessments for local improvements may increase the amount owed.
How to estimate Wisconsin property taxes
Start by entering the property’s estimated value. The calculator multiplies that value by the assessed-value percentage to estimate the assessed value. Any taxable-value reduction is then subtracted before the selected property tax rate is applied.
The basic calculation used by this estimator is:
Estimated taxable value × effective property tax rate − annual credits + special assessments
Where to find a more accurate tax rate
- Review the most recent property tax bill for the parcel.
- Check the local municipality or county treasurer website.
- Confirm the school district and other taxing jurisdictions.
- Use the actual net property tax amount and assessed value to calculate an effective rate.
Why nearby properties may have different tax bills
Two homes with similar market values may have different tax bills because they are in different municipalities, school districts, special districts or assessment classifications. Credits and special assessments can also change the final amount.
