The Wisconsin Department of Revenue (DOR), State and Local Finance Division posted the 2025 Preliminary Major Class Comparison Report (sec. 70.05 Assessment Compliance) on our website.

To receive a 2025 preliminary compliance calculation, a municipality needed to file these two reports by October 6, 2025:

• 2025 Statement of Assessment (SOA)
• Final 2025 Municipal Assessment Report (MAR)

Information

• SOA must be error free to use for compliance measurement
• If the municipality did not file 2025 information by October 6, the 2025 compliance is not displayed in this report and the preliminary compliance status appears as non-compliant
• If the 2025 compliance is not included in the preliminary report, DOR will review the late filed MAR and/or SOA in January 2026 and will include the compliance on the Final Major Class Comparison Report
• If the Final Major Class Comparison indicates a municipality is in compliance with sec. 70.05 Wis. Stats., DOR will rescind any notices issued due to incomplete information

Note: DOR will send the rescind notices when we post the Final 2025 Major Class Comparison Report in February 2026.
