The Town of Merton is conducting a Town Wide Re-assessment of properties this year.

Under the state law (sec 70.05(5)(b), Wis Stats) each municipality must assess all major classes of property within 10% of full value in the same year.  The Town's properties are currently assessed well below the market value, triggering the Town Wide Re-assessment.

Notices were mailed out to property owners on Tuesday,  June 24, 2025 from Catalis Tax & CAMA, Inc.

If you have not received a notice by July 1, please contact the Assessor using the contact information below.
