Fair Market value is based on the assessed value divided by the level of assessment. All valid commercial and residential sales are divided by their assessed value. The results are then weighted against total assessed values in the City of Oshkosh and the level of assessment is determined. This number is given to us by the State of Wisconsin Department of Revenue in the fall of the year.
Real Estate Tax information can be found by clicking exit above and going to the City Data Inquiry link.
