2017-2018 Assessment Notices have been mailed.  

The Assessor is required to appraise all properties at 100% of their true and fair market value, according to highest and best use of the property. Fair market value is the amount that a willing and unobligated buyer is willing to pay a willing and unobligated seller.

The new value represents market value as of January 1, 2017 based on market evidence from sales typically occurring last year. Market or sales comparison approach to value is determined, or estimated, based on multiple sales of similar properties. Most residential property is valued using this method. The data used to reach this value is available here.

If you believe that the new value is substantially incorrect or that an error has been made compared to your estimate of market value, please call the Assessor’s Office at (360) 679-7303 between 8:00 AM and 4:30 PM Monday - Friday.

You can talk or meet with your appraiser regarding your value, alert us to any changes in your property or let us know about ownership or address changes. If you are unable to reach us, consider protecting your right to an appeal by following the instructions for the Appeal Process. An informational pamphlet describing the property tax system is also available.

As your Assessor, one of my functions is to have this office be transparent and accessible to you. This web section will provide you with information and assistance on questions you may have regarding the Assessor’s office. If you have any other questions or concerns that are not addressed here, please contact me.

It is our goal to appraise all property fairly and equitably, to maintain accurate and accessible property records and give prompt and courteous customer service.

State law requires that the Assessor value property at 100% of true and fair market value. The market value is determined by the property owners who are buying and selling real estate in the market place. Finding the market value of your property means discovering the price most people would pay for your property.

What We Do

The Island County Assessor’s office is required to physically inspect, appraise and revalue all real property once every 6 years with an annual review and update based on sales analysis.

In order to do our job we:

  • Maintain inventory, description, ownership, sales and mapping for all properties
  • Provide information, education and assistance
