Mission Statement
Our mission is to serve the citizens of Skagit County by striving for the highest level in equity of assessment, efficiency of operation, and professionalism of our staff.

Was your property adversely affected by the recent flood?

All taxpayers have the right to a reduction in the assessed value of destroyed property . The assessor's office has a form to complete for property that has been involuntarily destroyed in whole or part in the last three years.

Appraisers from the Assessor’s Office will be conducting field surveys in areas of the county most impacted by recent flooding. Mass adjustments to assessed value will be applied based on three general levels of impact. Since this is a natural disaster, value adjustments will apply to the current tax year to result in prorated abatements on affected parcels.

The field survey will not include the entire county so owners of flood affected property are encouraged to submit a Damage Assessment Report (in English here, in Spanish here) to Skagit County Department of Emergency Management. Damage Assessment Report questions can be directed to the DEM at 360 416-1850 or email . Tax abatement questions can be directed to the Assessor’s Office at 360 416-1780.

Skagit assessed value trend mirrors state median home price

Property values are rising all over Skagit County.  Housing prices are being driven by our area’s hot housing market, where high demand and low supply are driving sales prices upwards.  This trend is not only occurring in Skagit County, but also across the State of Washington.  This can be seen in comparing the assessed value increases in Skagit County versus the median sales price in the State of Washington.

2021 Assessed Values Are Now Certified

The assessed values for 2021 have been certified and appear on the county website using Property One Stop. Value notices are scheduled to be mailed next week. Approximately 56,000 parcels are included in the assessment update completed by the Assessor staff. [more]

About the Assessor's Office

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.
