Mission Statement

The Blaine County Assessor’s Office strives to provide an optimal level of service, information, and policy guidance to the public and to other government agencies.

Welcome Message from the Assessor

Welcome to the Blaine County Assessor's website. This site has been prepared to help you better understand the functions of the Assessor's office. The information contained herein will assist you, as a property owner and taxpayer, in understanding assessment procedures, tax collection, and distribution of the tax dollar.

The Assessor does not establish the dollar amount of taxes required nor does the Assessor bill or collect taxes. The taxpayer, state limitations and assessed value determine the tax rate for each district. The County Treasurer bills and collects the required tax.


It is my responsibility as your Assessor, together with my staff, to insure that all property owners are treated fairly and impartially in accordance with our state laws. It is our sincere desire to serve and support you in an effective, responsible, and courteous manner.


The County Assessor's office welcomes your inquiries and concerns on how your property is assessed. As your Assessor, I am committed to serve and assist you personally in any matters dealing with this office. Also, I will be available to speak to and/or answer questions for interested groups. Please contact the Assessor's office for more information. Office hours are 8 a.m. to 6 p.m. Monday through Thursday. The phone number is 208-788-5535.
