Property Tax Bills Across Fond Du Lac County, Wisconsin
Property tax bills in Fond du Lac County are calculated by applying the local tax rate to a home’s assessed value, which is based on the market value of the property. Local taxing authorities then use that assessed value to determine how much each homeowner owes, so the bill can vary widely from one property to another. Factors such as location, home characteristics, and changes in market conditions all influence the assessed value and, in turn, the final tax bill.
For homeowners, this means a higher assessed value usually leads to a higher property tax bill, while a lower assessed value can reduce what is owed. In Fond du Lac County, the median home price is $185,570, and tax bills range from $1,992 at the 25th percentile to $4,026 at the 75th percentile, with the 90th percentile reaching $5,373. Bills also differ by city, with Eldorado showing the highest median tax bill at $3,672 and Fairwater the lowest at $1,509.
