What are the property tax rates and typical annual property tax bills for a $250,000 home in Fond du Lac city limits versus nearby Town of Fond du Lac in October 2026

Basic method. Property tax bills start with the assessed value, which is converted to a taxable value after any exemptions, then multiplied by the combined mill rate from city or town, county, school district and other local levies.

Taxable value versus market value

Assessment basics. Fond du Lac County assessors set an assessed value for each parcel. That figure can differ from sale price or market value. Wisconsin then applies any statutory exemptions and adjusts assessments to determine the taxable value used for billing.

What combines to form your mill rate

Components. Your total mill rate includes the City or Town levy, Fond du Lac County levy, school district levy, technical college and any special districts. Each of these publishes a mill rate that adds together into the final rate on your tax bill.

2. Estimated tax calculation for a $250,000 home in Fond du Lac city limits

Direct answer. To estimate a typical annual bill for a $250,000 home inside Fond du Lac city limits, multiply the property's taxable value by the combined city, county, school and other mill rates; the calculation below shows the steps and sample numbers you can replace with current local mill rates.

Step by step example. Assume the assessed value for a $250,000 sale equals $250,000 and taxable value is the same after exemptions. If the combined mill rate were 25 mills, the math would be: Taxable value $250,000 divided by 1,000, multiplied by 25 mills equals $6,250. Replace 25 with the current combined mills for your exact bill.

Typical local numbers to look up

Where to get mill rates. Fond du Lac County publishes mill rates and levy details each year. Use the county Treasurer mill rates page to get the city component and county component for October 2026 before you run the calculation.

3. Estimated tax calculation for a $250,000 home in the Town of Fond du Lac

Direct answer. Estimating a Town of Fond du Lac bill uses the same math as the city example, but you must use the town mill rate in place of the city levy; the town mill rate may have a different municipal component and possibly different special district charges.

Sample calculation for comparison. If a $250,000 home's taxable value is $250,000 and the combined Town of Fond du Lac mill rate were 22 mills, your annual tax would be $250,000 divided by 1,000, times 22 mills, or $5,500. Swap in the official town mills to get an accurate number.

Town-specific items to verify

Check special districts. Towns sometimes belong to different sanitary, fire or utility districts than the city. Those special district levies appear on town tax bills and should be included when you estimate annual taxes.

4. How to check the official mill rates and confirm your estimate

Direct answer. Confirm your numbers using the county mill rates page and the Wisconsin Department of Revenue bulletin on town, village and city taxes, then plug those mills into the calculation shown earlier.

Useful official sources. Fond du Lac County mill rates are published by the county Treasurer, and the Wisconsin Department of Revenue posts a Town, Village and City Taxes bulletin explaining municipal taxing rules; use both before you finalize an estimate.
