Role and Mission

The Assessor's primary responsibility is to identify and assign a taxable value (assess) to all real and tangible business personal property within San Juan County and certify the annual tax roll with the Washington Department of Revenue (DOR) in accordance with State law. Additional responsibilities include the maintenance of all associated property records, the administration of current use and exemption programs, and the annual notification to property owners of a change in their appraised property value.

Property taxes allow our community to benefit from services like schools, libraries, parks, health services, fire protection, and law enforcement. The Assessor administers the assessment process so that taxes are paid equitably according to State law. The San Juan County Assessor's Office is committed to a process that is professional, fair and clearly understood.
