Bellingham Overview
Whatcom County Assessor - Bellingham Records
The Whatcom County Assessor's Office determines and sets the value of all real and taxable personal property in Whatcom County, including every parcel inside Bellingham. The assessor appraises all real property each year and physically inspects one-sixth of all properties on a rotating cycle. That means your property gets a physical visit roughly once every six years in addition to the annual data review.
The Assessor's Office is at 311 Grand Ave, Suite 106, Bellingham, WA 98225. Phone: 360-778-5050. Fax: 360-778-5051. Hours are Monday through Friday, 8:30 AM to 4:30 PM. The office publishes an annual tax booklet with assessed valuations, tax rates, and taxes levied for each taxing district in the county. You can pick one up at the office or find it online.
The assessor maintains a complete inventory of all property in the county, including ownership records, legal descriptions, sales data, and maps. These records are used to allocate value to taxing districts and calculate levy rates each year. The assessor then certifies the tax roll to the Treasurer, who handles billing and collection.

The Whatcom County Real Property Search lets you search Bellingham parcels by property ID, parcel number, address, or owner name.
The search results display taxes and assessment details, values, mapping links, taxing jurisdiction information, building details, property images, land data, roll value history, deed and sales history, and payout agreements.
Searching Bellingham Property Tax Records Online
Whatcom County offers free online access to property tax and valuation data through its Real Property Search portal at property.whatcomcounty.us. Search options include Property ID, Parcel Number, Address, and Owner Name. Clicking "Advanced" reveals additional filters if you want to narrow results by appraisal year or other criteria.
When viewing a property detail page, you can see current and prior year tax statements with first-half and second-half base amounts, any penalties and interest, and the total amount due. To see the most current ownership information, set the results display to the 2026-2027 appraisal year in the search settings. The portal notes that accuracy is not guaranteed and recommends contacting the assessor to verify data for legal or financial decisions.
Whatcom County also maintains an interactive GIS map for viewing tax parcels. The parcel viewer at property.whatcomcounty.us/Map lets you search by address and view parcel boundaries over aerial imagery and topographic basemaps. Clicking a parcel links directly to the Real Property Search detail page for that property. The map is useful for visualizing Bellingham property locations, adjacent parcels, and surrounding land use.
For recorded documents such as deeds, liens, and easements, the Whatcom County Auditor's Office handles document recording and maintains the official records. The Auditor's records are separate from the Assessor's records and can be searched to trace ownership history or find recorded encumbrances on a property.

Bellingham Property Tax Exemptions
Whatcom County administers the Senior Citizen and People with Disabilities Property Tax Exemption program for Bellingham property owners who qualify. The county uses a new online filing portal powered by Just Appraised. Applicants can apply, upload documents, and check their application status online with email updates throughout the process.
To qualify, you must meet four requirements: age or disability, ownership of the property, occupancy as your primary residence, and household income within the county's current limit. For 2026 taxes, the income limit is $52,000 in disposable income. Three exemption levels exist based on income. At the lowest income bracket, you receive the most relief. At higher income levels within the qualifying range, the exemption is partial.
Required documents typically include a federal income tax return, a valid driver's license, and proof of deductible expenses. Applications can be filed online or in person at 311 Grand Ave Suite 106, Bellingham, WA 98225. Late applications for previous years are accepted within 3 years of the tax due date if you are seeking a refund. The program is authorized under RCW 84.36.381.
If your exemption application is denied, you can appeal to the County Board of Equalization by July 1 or within 30 days of receiving the denial notice, whichever comes later. Contact the Whatcom County Assessor at whatcomcounty.us/265 for full details on current income limits and required forms.
