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.


2022 Assessed Values Are Now Certified

The assessed values for 2022 have been certified and appear on the county website using Property One Stop. Value notices are scheduled to be mailed October 14. Approximately 62,000 parcels are included in the assessment update completed by the Assessor staff. Reappraisals occurred in the Burlington Edison School District with physical inspections while the remainder of the county was updated statistically through the annual ratio study. Significant value increases occurred in many property categories and areas, reflecting the appreciating real estate market in effect during the study period.

Assessors are required to maintain assessments reflecting market value. The assessment ratio is the measure of assessment level to market and at 92.6 percent for 2022, is consistent with prior years. That measure means on average, assessed value is 92.6% of selling price on properties that sold during the May 1, 2021 to April 30, 2022 period. The effective date of value for assessment purposes is January 1, 2022. Property with new construction is valued on its completion status as of July 31, 2022.

Property owners with questions concerning the new value are encouraged to call the Assessor’s Office. If you did not receive a notice, the assessed value did not change from the prior year. In either case you may appeal the 2022 value by submitting a real or personal property petition to the Board of Equalization by November 14.    

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.

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.
