Island County Property Tax Records

Island County property tax records are managed by the Assessor and Treasurer offices in Coupeville, covering all parcels on Whidbey Island and Camano Island. You can search assessment data and pay taxes through the county's PACS online portal. The county also maintains a GIS map viewer and offers several exemption programs for qualifying residents. This page explains how to find and use Island County property tax records.

Island County PACS Property Search

The main online tool for Island County property tax records is the Island County PACS property search portal. The system offers several search options, and you can click the Advanced button for more refined queries. Geographic IDs in Island County follow one of two formats: RXXXXX-XXX-XXXX for metes and bounds parcels, or SXXXX-XX-XXXXX-X for plats and condos. For property address searches, the county advises using only the street name (without directional prefixes or suffixes) to get the best results. If a full name does not return results, try the first few letters of the street name.

The PACS portal also has Sales Search and Map Search options accessible from the application header. To see current ownership data, change the Results Display setting to 2026-2027. The Island County Parcel Search landing page provides a disclaimer about data accuracy and important contact information. The Assessor can be reached at AssessorEmail@islandcountywa.gov, and the Treasurer at treasurerwebinfo@islandcountywa.gov. Online payments are now available through the Island County Treasurer via WA Payments.

Note that if a parcel is in active foreclosure proceedings, the online balance may not reflect all costs and online payment may not be accepted. Contact the Treasurer's office directly in those cases to confirm the correct amount owed and how to pay.

Island County properties are physically inspected once every six years, with annual sales analysis updates in between.

Island County Assessor Office

The Island County Assessor's Office is responsible for physically inspecting, appraising, and revaluing all real property in the county at least once every six years, with an annual review of sales data in between. The office maintains inventory, ownership records, sales history, descriptions, and mapping for every parcel on the islands. Public computer access to assessment data is available at the Assessor's office for those who need it.

The Assessor allocates value to each taxing district, calculates levy rates, and certifies the tax roll to the Treasurer each year. The Assessor does not mail or collect taxes. That is handled by the Treasurer, whose office can be reached at 360-679-7302. The Assessor also does not handle appeals. The Board of Equalization manages the appeal process and can be reached at 360-679-7379.

Island County administers several tax exemption programs. Qualifying property owners include senior citizens and disabled persons, as well as owners of open space, forest land, farm and agricultural property, historic properties, and residential home improvement projects. Each program has its own eligibility rules. Contact the Assessor's office to ask which programs apply to your property and how to apply. The Washington Department of Revenue has statewide information at dor.wa.gov.

Reading Your Island County Tax Statement

The Understanding Your Tax Statement page explains the different components of an Island County property tax bill. GEO parcel numbers follow a format that tells you the property type. Numbers starting with "S" are plats and condos. Numbers starting with "R" are metes and bounds parcels. Numbers starting with "M" are manufactured or mobile homes. Each parcel also has a Property ID Number (PID), which is a randomly assigned 3 to 6 digit number used by the Treasurer to reference the account.

The Tax Code Area on your statement tells you which taxing districts your property falls in. This determines where your tax dollars go. The Tax Distribution section of your statement breaks it all out: state schools, county general fund, roads, fire districts, and other local services all receive a share based on the levy rates. Your total tax is simply the levy rate multiplied by your assessed taxable value. Common benefit-fee assessments you may see include Forest Protection, Clean Water Utility, Conservation District, Mosquito Control, and Diking and Drainage Districts.

Note: If you see a change in your tax amount from one year to the next, it may be due to a change in your assessed value, a voter-approved levy change, or a shift in one of the benefit-fee assessments on your statement.

Island County ICGeoMap and GIS Tools

Island County offers the ICGeoMap interactive GIS viewer for parcel and geographic data. The map is accessible from the Assessor's online menu. It lets you zoom, pan, and query parcel boundaries and related property attributes. The viewer integrates with the PACS database to show spatial property information alongside tax district boundaries, zoning, and aerial imagery. This is useful for confirming parcel locations, seeing neighborhood context, and verifying tax code areas before filing an appeal or completing a transaction.

For broader state property tax information and guidance, the Washington Department of Revenue offers resources at dor.wa.gov/taxes-rates/property-tax. Property value appeals that go beyond the county Board of Equalization are handled by the Washington State Board of Tax Appeals at bta.wa.gov.
