Preliminary Major Class Comparison Report for 2018

Division of State and Local Finance
Equalization Bureau

Under state law (sec 70.05(5), Wis. Stats.), each municipality must assess major classes of property within 10 percent of full value in the same year, at least once within a 5-year period. If the municipality is non-compliant after four consecutive years, the Wisconsin Department of Revenue (DOR) must notify the municipality of its non-compliance status. DOR issues the municipality a second non-compliance notice after five consecutive years of non-compliance, and issues an order for supervised assessment after six consecutive years of non-compliance.

The Major Class Comparison Report provides a history of each municipality's assessment compliance.

Definitions of terms in the report:

  • EQ Admin Area - Equalization Bureau District Office that determines the municipality's Equalized Value
  • County - county where the municipality is located
