How often must counties in Wisconsin conduct property revaluations?

Counties in Wisconsin are required to conduct property revaluations every 5 years to ensure that property assessments are current and reflective of market conditions. This practice helps maintain equity in tax distribution, as property values can change due to various factors such as market fluctuations, changes in property characteristics, or development in the area. Conducting revaluations on a five-year cycle enables assessors to accurately capture these changes and adjust property values accordingly. This timeframe strikes a balance between the need for updated valuations and the resources available for conducting comprehensive assessments throughout the county. Regular revaluations help ensure that property taxes are fairly levied, aligning property assessments with current market values.
