Wisconsin real and personal property tax records are managed by the County Assessor in each Wisconsin county. Land and land improvements are considered real property while mobile property is classified as personal property.Many County Assessors provide an online searchable database, where assessment record searches can be performed by address, owner name, tax year, or parcel identification number. Where online records are not available, requests for records can be made to the County Assessor in person, by phone, or in writing.
