Personal Property Standards Committee   Chairperson,  Mark Hanson, Madison  (608) 266-4257 

This WAAO committee analyzes proposed personal property legislation, periodically reviews statutes, case law, and legal opinions and suggests consistent policy positions to the WAAO leadership.


2017 Wisconsin Act 59 exempted machinery, tools and patterns, except those used in manufacturing, effective January 1, 2018.

The statute reads, in part:

“70.111(27) MACHINERY, TOOLS, AND PATTERNS. (a) In this subsection, “machinery” means a structure or assemblage of parts that transmits force, motion, or energy from one part to another in a predetermined way by electrical, mechanical, or chemical means. “Machinery” does not include a building. (b) Beginning with the property tax assessments as of January 1, 2018, machinery, tools, and patterns, not including such items used in manufacturing.”

WAAO recommends assessors discuss the application of this statute with their municipal officials or legal advisors.  Personal property statements that do not reflect the meaning of this statute may prompt inquiries from the assessor.
