The Wisconsin Department of Revenue (DOR), State and Local Finance Division would like to remind you of two upcoming due dates for e-filing the Municipal Financial Report (MFR).

• May 1, 2026 – populations over 2,500
• May 15, 2026 (extension) – DOR automatically grants an extension for all municipalities and counties. You do not need to send an extension request.

Form Information

MFR forms are available on our website and e-filed through MyDORGov. Make sure to choose the correct form.

• Form A – for counties
• Form C – for cities and villages (and towns with proprietary funds)
• Form CT – for towns (without proprietary funds)

Late Filing or Non-filing

• Late filing – if DOR does not receive a complete and accurate form by the extended due date (sec. 86.303(5)(f), Wis. Stats:
  • Your county/municipality is charged a late filing penalty, which reduces your General Transportation Aid payments
  • This penalty is calculated and imposed by the Wisconsin Department of Transportation
• Non-filing – if DOR does not receive your form:
  • DOR may request that a certified public accountant complete the form using your county/municipal records
  • Your county/municipality is charged for this service
