​​​​​The Wisconsin Property Assessment Manual (WPAM) serves as the guide for uniform property assessment. Sec. 70.32, Wis. Stats., requires that assessors utilize the WPAM when valuing real property. Section 70.34 , Wis. Stats., requires its use when valuing personal property. 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 and is updated on an annual basis.

The WPAM has been posted to the Department of Revenue's website. It can be found at: www.revenue.wi.gov/​Documents/wpam11.pdf.

The file is 15 MB and may take a few minutes to download, depending on the internet service you have. We suggest you save a copy to your desktop if you anticipate using the manual often.

The significant changes are described in the second to last PDF item. As with any change in a process, you may identify issues. If so, please send the Bureau of Assessment Practices a message with your feedback or questions to: bapdor@wisconsin.gov.
