Find Property Tax Records in Snohomish County

Snohomish County property tax records are maintained by the Assessor's Office in Everett and are accessible online through the county's SCOPI mapping tool and property account system. You can search by parcel number, owner name, or address to pull assessed values, sales history, tax account details, and building data for any parcel in the county. This page explains how to use those tools, how the assessment process works, when taxes are due, and where to turn for exemptions or appeals.

Snohomish County Assessor Property Tax Records

The Snohomish County Assessor's Office is responsible for updating assessed values for all real and personal property in the county each year and for calculating levy rates for all taxing districts. County Assessor Linda Hjelle leads the office, with Laura Washabaugh serving as Chief Deputy Assessor. The Customer Service Center is on the first floor of the Robert J. Drewel Building at 3000 Rockefeller Avenue, Everett, WA 98201. The mailing address adds M/S 510 to that address. Email the office at contact.assessor@snoco.org.

The Assessor's website gives you direct access to property information, exemption forms, property-tax-related statutes, and the SCOPI mapping tool. Department phone numbers are divided by function: Main Line (425) 388-3433, Residential Appraisal (425) 388-6555, Commercial Appraisal (425) 388-3390, and Exemptions (425) 388-3540. Assessment rolls and parcel legal descriptions are free to download in CSV and Excel formats and are updated three times per week.

Search Snohomish County Tax Records with SCOPI

SCOPI (Snohomish County Online Property Information) is the county's primary tool for searching property tax records. It is an interactive web map that lets you find any parcel by address or parcel number. Clicking a parcel on the map shows basic data right away: Parcel ID, property address, owner name, taxpayer name, gross acres, market value, and Tax Code Area number. From there you can open the full Property Account Summary in a new tab.

The Property Account Summary includes sales history, property tax history by year, legal descriptions, and detailed structure data. Recent sales layers on the SCOPI map highlight valid market transactions for single-family homes, manufactured homes, duplexes and triplexes, and condominiums. Aerial imagery layers go back to 2017, including 3-inch resolution urban photos from 2022. The county captured those urban photos between April 6 and July 11, 2022 and rural photos between May 31 and August 11, 2022.

Appraisal neighborhoods are shown as overlays with 7-digit IDs. Residential neighborhoods start with digits 1 through 4. Commercial neighborhoods start with 5 or 6. The Neighborhood Search tool pans and zooms to your selected area. Parcels without a number show as Shared Interest Parcels (common condominium elements) or "Not a Legal Tax Parcel" for gap areas. The tool also flags properties with multiple tax parcels.

PDF guides for both desktop and mobile users are available on the SCOPI page. Use Chrome or Edge for best results, as high-resolution building photos may not display in Internet Explorer.

Note: SCOPI data is updated regularly but may have a short lag after new recordings or assessments are finalized.

How Snohomish County Property Tax Assessment Works

Washington State requires all property to be assessed at 100% of fair market value under RCW 84.40. The Snohomish County Assessor updates values every year using sales analysis and mass-appraisal methods. Physical inspections of each property must happen at least once every six years under state law.

The Levy division in the Assessor's Office calculates tax rates and maintains Tax Code Areas (TCAs) across the county. Each TCA reflects the combination of taxing districts that serve a given parcel. Your rate depends on which school districts, fire districts, EMS levies, and other local taxing authorities cover your area. In 2023 the typical levy rate dropped to $7.6109 per $1,000 of assessed value, down from $9.3017 in 2022. That drop came largely from higher assessed values spreading the same total levy across a larger base.

Total taxable assessed value grew from $170 billion in 2022 to $219 billion in 2023. That jump reflects broad market appreciation across the county's suburban and urban areas. In the Marysville area, residential values rose an average of 27%, yet taxes fell an average of 25% because two school levies expired and were not replaced. In the Mill Creek area, taxes rose roughly 30% due to annexation into the South County Regional Fire Authority and new Everett School District levies.

New construction assessment dates are July 31 each year for taxes to be collected the following year. Business personal property is valued annually based on depreciated cost reported by owners. Destroyed property claim forms can reduce assessments and trigger potential tax abatements after events like flooding.

The DOR site covers levy limits, assessment standards, and programs that apply across all 39 Washington counties, including Snohomish.

Snohomish County GIS and Property Mapping Tools

The Assessor's GIS and Mapping division maintains cadastral land ownership data, taxing district boundaries, and Public Land Survey data in GIS-compatible formats. Popular open data layers updated three times per week include Current Parcels, All Parcels (past and present), Easements, Parcel Centroids, Subdivision Boundaries, and Tax Code Areas. Tabular downloads include the Assessment Roll in CSV and Excel, Parcel Legal Descriptions in Excel, and a Plat Listing with hyperlinks.

Recent property sales data is updated quarterly on the County's Open Data Portal. TRSQ Maps are also available as downloadable .TIF and .PDF files for parcel-level reference. All GIS data and maps are provided for illustrative purposes only and are not official citations to the Snohomish County Code. Some data used by the county is proprietary, like certain aerial imagery and street center lines, and cannot be redistributed.

Under RCW 42.56.070(8), public records lists of individuals cannot be used for commercial purposes. Users must agree not to compile individual lists for profit when downloading Assessor data.

Snohomish County Property Tax Payment

The Snohomish County Treasurer's Office handles all property tax billing and collection. The mailing address is Snohomish County Treasurer, 3000 Rockefeller Ave, M/S 501, Everett, WA 98201.

The Treasurer mails tax statements in mid-February each year. Under RCW 84.56, if your total bill exceeds $50, you can split payment into two halves. The first half is due April 30. The second half is due October 31. The Treasurer notes that mail processing may take until May 15 for the first half and November 15 for the second half during heavy payment periods.

You can pay online through the Treasurer's website, by phone at 833-440-3332, by drop box on the county campus (checked daily), or by mailing a check. Credit and debit card payments are accepted online and by phone. Name and address changes can be submitted electronically, on the back of the tax statement, or by email with your parcel information.

Mortgage companies may pay on your behalf. If they do, your statement is for informational and IRS reporting purposes. Interest and penalty waivers may be available after the death of a taxpayer. Call 425-388-3366 for the waiver form. Mobile home ownership transfers are processed through the Treasurer's Office, and English and Spanish guides are available online.

Note: If a new exemption application is pending, pay the regular amount until approval. After approval, the tax is recalculated and a refund check is issued.

Snohomish County Property Tax Exemptions

The Assessor's Office administers several property tax relief programs for Snohomish County residents. The Senior Citizen and Disabled Persons Exemption is the most widely used. For 2024, the income limit was raised to a maximum of $75,000 in disposable income. You must own and occupy your home as your primary residence to qualify. Call 425-388-3540 or email assessor@snoco.org for exemption help.

Other programs available through the county include:

• Limited income deferral program for qualified homeowners

The application and brochure for the Senior Citizen and Disabled Persons Exemption are linked directly on the Assessor's website, along with an online status check tool for submitted applications. Once approved and sent to the Treasurer, the tax is recalculated and you get 30 days to pay the corrected amount without interest or penalty. The full statewide list of programs and income thresholds is at the DOR exemptions and deferrals page.

The state image below from the DOR exemptions page shows which programs are available across Washington.

These programs apply in Snohomish County and are processed through the Assessor's Office in Everett.

Appealing Snohomish County Property Tax Values

If you believe your assessed value is too high, you have the right to appeal. Start with the Assessor's Office. Talk with the residential or commercial appraisal team about how your value was reached. A data error in the property record, like a wrong bedroom count or an improvement attributed to the wrong parcel, can sometimes be fixed without a formal filing.

Formal appeals go to the Snohomish County Board of Equalization. You must file within 60 days of the notice mailing date or by July 1, whichever is later. Appeal forms and instructions are on the Board of Equalization website. Bring comparable sales data or other evidence of a lower market value. If the Board's decision does not resolve the dispute, you can escalate to the Washington State Board of Tax Appeals, which handles appeals from all county boards across the state.
