Welcome from the Assessor

Welcome to the Grant County Assessor’s Web site. 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 the assessment procedures, tax collection and distribution of your tax dollars.


The Assessor does not establish the dollar amount of taxes required nor does the Assessor bill or collect taxes. The voters, the State limitations and assessed value determines the tax rate for each taxing district. The Assessor is responsible for checking the amounts asked for by the taxing districts to make sure they are within the limits set by state law. We also compile all the different levy rates in your taxing areas to determine the total tax rate for your property. It is the responsibility of the Grant County Treasurer to bill and collect the required taxes.


There are several lesser-known functions the Assessor’s office performs. These include maintaining maps of all of Grant County, including all cities and towns within the county. These maps represent the boundaries of each parcel in Grant County. The office records and updates the ownership and legal description of every piece of property within Grant County. This requires the Grant County Assessor’s office to track and maintain approximately 61,570 parcels for the benefit of all the citizens of the county.


It is the responsibility of the Grant County Assessor, together with her staff, to insure that all property owners are treated in a fair, equitable and impartial manor in accordance with our state laws. It is our sincere desire to serve and support you in a professional, effective, responsible and courteous manner.


The Grant 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 Grant County Assessor’s office for more information.
