Appraisers working door to door in Mount Vernon
Skagit County Assessor's Office appraisers are actively doing physical inspections in the Mount Vernon area. Inspections within the Mount Vernon School District started in October 2014 and are expected to be completed by mid-June 2015. The twelve appraisers in the field will be knocking on doors, talking with the residents and are tasked with viewing all parts of the property for each address they inspect.
Cooperation from the public is greatly appreciated.

The assessor acts as an agent for the Washington State Department of Revenue and is responsible for administering the property tax system for the county. This process involves establishing real and personal property values for distributing taxes for each tax district, as well as reviewing each tax district’s budget request to assure all legal requirements and limitations are met. The assessor also administers and monitors compliance for recipients of tax benefit programs, such as the Senior Citizen and Disabled Exemption program and the various Current Use programs for properties used for agriculture, timber and open space.
