If you disagree with the County Assessor’s valuation of your property, you have the right to appeal.

What does the Board of Equalization do?
The Board of Equalization assists in the administration of property valuation, providing an impartial citizen forum for property owners. If a property owner disputes the assessed value of property, the Board of Equalization may hear the property owner’s appeal and make a decision.
Remember - the Board of Equalization deals with valuation, not taxes. Your taxes are based on the valuation of your property. If you have a question regarding your property taxes, please contact the Cowlitz County Treasurer’s Office.
Questions regarding the value of your property?
If you have questions or changes regarding the value of your property we encourage you to contact the Assessor’s Office at 360-577-3010. If it appears an error may have been made, the department can conduct an assessment review and, if indicated, adjust the assessed value of the property.
