Property Tax in Marathon County, Wisconsin
The median real estate tax bill in Marathon County, Wisconsin is $3,108 per year, and the median home is worth $205,500. Both figures are the US Census Bureau's survey medians for owner-occupied households (US Census Bureau, American Community Survey (ACS) 5-year estimates, 2023).
What the Marathon County numbers mean
The median is the midpoint of the county's actual bills: half of Marathon County homeowners pay more than $3,108 a year and half pay less. The exact bill for any one home depends on its assessed value, exemptions, and which school, municipal and special districts cover it.
Set against the median home value of $205,500, the median bill works out to a derived effective rate of 1.51%. That rate is an estimate computed from the two medians — no county publishes a rate calculated this way — but it adjusts for home prices, which makes comparisons between counties more meaningful.

How the tax is worked out
As an illustration of the arithmetic: at Marathon County's derived rate of 1.51%, a home valued at $400,000 would carry a tax bill of roughly $6,048 a year. That is only an illustration using the derived rate — a real bill is computed from the property's assessed value, its exemptions, and the combined rates of its specific taxing districts, so it can be higher or lower.
The usual sequence is: the local assessor values the property; exemptions are applied; the taxable value is multiplied by the combined local rates; and the county bills and collects the tax, distributing it to the schools, municipalities and districts that levied it.

Checking your assessment in Marathon County
