The Wisconsin Department of Revenue (DOR) would like to inform you of changes to the property tax bill backer for the 2019 tax year. The updated property tax bill backer is available on our
Property Tax Bills web page.
The updated backer must be used for 2019 property tax bills. The major changes include:
- Additional explanation related to estimated fair market value
- Contact information updates for property tax relief options
Estimated Fair Market Value
Under state law (sec. 74.09, Wis. Stats.), municipalities are required to show the estimated fair market value on property tax bills for all classifications except agricultural land, as defined in
sec. 70.32 (2)(c)1g., Wis. Stats. Estimated fair market value is the property's assessed value divided by the municipality's average assessment ratio. If a parcel consists of multiple classifications, the total estimated fair market value is displayed, excluding agricultural land.
Since class 5 – undeveloped and 5m – agricultural are assessed at 50 percent of full value, calculate the total estimated fair market value by doubling the assessed value, then dividing it by the municipality's average assessment ratio.
