Can I dispute my property assessment (Open Book)?

How can I change my mailing address for tax billing purposes?

I own two adjacent properties. Can I combine the two properties into one tax bill? If so, what is the process for doing so?

For properties that are located within one of the Townships of Outagamie County, parcels need to be combined as outlined in the Outagamie County Subdivisions and Platting Ordinance. A Certified Survey Map (CSM) is required and the process is similar to splitting an individual property into two or more parcels. Click here to learn more about the CSM process.
Properties located within a City of Village may combine/split a parcel or parcels with approval from your Municipal Clerk and your local Assessor. A letter signed by the Municipal Clerk and ALL owners of the parcel or parcels can be emailed to the Real Property Lister, Terri.Lison@outagamie.org. Combine/splits will be processed for the following Tax Roll Year. For example, a request received on June 10, 2023 would be reflected on the 2024 Tax Bill. Please contact your Municipal Clerk as well as your local Assessor for information regarding how this may or may not affect your property assessments.

What are my property and improvement assessments?

Please visit the Outagamie County Ascent Land Records website. Search your property by parcel ID #, Street Number/Name, or by Name. Once the record is found click on "Select Detail" and then "Assessments". If you have further questions regarding the details of your assessment, please contact your local Assessor.
