To: County and Municipal Clerks
Cc: County and Municipal Treasurers

The Wisconsin Department of Revenue (DOR), State and Local Finance Division would like to remind you of today's filing deadline for the Maintenance of Effort Report (Form SL-305).

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.

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

Non-filer List

  • As of today, July 1, 2025, there are 38 municipalities that still need to file this report (see MOE Non-filer Report)
  • If your municipality is on the non-filer list and you think your form was already submitted, verify your submission
    • Go to MyDORGov to see the report's filing status – on the "form filing" page, check the "Filing Status" column for that form
    • Reminder: To file the report, you must click "Submit" on the left blue panel within the report
