Use our online calculator to estimate how the 2025 property revaluation may impact your taxes. The calculator is based on 2025 tax rates and includes the 2025 impact of the Wauwatosa School District referendums. In 2024, the average home in Wauwatosa was assessed at $274,100. Following the revaluation, the new average is $418,800. The citywide revaluation increased property assessments by an average of 44.7%. However, this does not mean your property taxes will rise by the same percentage, your taxes will rise or fall due to the revaluation depending on how your assessment change compares to this 44.7% average. The increase reflects how property values have grown across Wauwatosa in recent years. This tool helps you understand the estimated impact of the change in your property’s assessed values on your property taxes. The impact of the revaluation is shown as a stand-alone number but is blended into each tax amount of the 2025 Taxing Authority section. This tax calculator does not include the lottery credit or first dollar credit.
