AB 603 Wisconsin Assembly · 2025-2026 Regular Session

Relating to: providing written notice of tax assessor entry upon property. (FE)

AB 603 requires tax assessors to provide property owners with written notice at least seven days before entering their real property for assessment purposes. This bill directly affects residential and commercial property owners by giving them advance written notification of an assessor's planned visit. The key provision mandates that the taxation district must deliver this written notice in advance, ensuring property owners are informed of the assessment activity before it occurs. The bill creates a new statutory requirement (70.05 (4j)) to formalize this notice period.
