The Wisconsin Department of Revenue (DOR), State and Local Finance Division is providing forms to comply with the Maintenance of Effort (MOE) reporting requirements created under 2023 WI Act 12.

For the 2025 reporting period, municipalities and counties must certify to DOR that the law enforcement, fire and EMS services provided for calendar year 2024 are at least equivalent to the level of service provided for calendar year 2023. We recommend reviewing the common questions before filing.

Maintenance of Effort Report

Every municipal and county clerk must submit a completed report to DOR.

Satisfying the Requirements

  • Under state law (sec. 79.039(1), Wis. Stats.), your district is assessed a penalty if:
    • DOR does not receive a complete and accurate MOE Report (Form SL-305) by July 1, 2025, or
    • Your district is unable to certify the appropriate level of service was maintained comparing calendar year 2024 to calendar year 2023
  • Penalty reduces aid payments – the penalty reduces county and municipal aid payment and the supplemental county and municipal aid payment by 15% the following year (secs. 79.036 and 79.037, Wis. Stats.)
  • DOR posts the MOE penalty report – on or before September 15 each year
