The complete Wisconsin Property Assessors Manual is now available online.

The manual aids assessors in the interpretation of statutes related to classifying and valuing property, describes the property assessment cycle and deadlines, and defines the responsibilities of public servants charged with carrying out property valuation. The manual is developed and maintained by the Department of Revenue, Bureau of Assessment Practices per WI Stats. 73.03(2a) and is updated on an annual basis.
