The Department of Assessment is charged with discovering, valuing, and maintaining accurate records of all taxable real property within the Ketchikan Gateway Borough and personal property within the corporate boundaries of the City of Ketchikan in order to provide a fair and equitable basis for property taxation.

The department is required by state law to make an independent estimate of “full and true value” each year as of the annual assessment lien date of January 1. To accomplish this, physical inventories of property characteristics are gathered and maintained for valuation purposes.

The department also administers property tax exemption programs as authorized by Alaska State Statute and Ketchikan Gateway Borough Code.
