Seattle Property Tax Statements, Payments and Tax History
Seattle property taxes are paid through King County Treasury / property tax tools. Use King County property tax resources when you need the tax statement, payment amount, payment history, due dates or bill information.

Seattle Deeds, Mortgages, Liens and Recorded Documents
King County Recorder’s Office holds real property records for Seattle properties, including deeds, easements, mortgage documents, liens and bills of sale. The online Landmark Records Search lets users search by name, document type, book/page, parcel ID, recording date and other document clues.
If you purchased a property in 1991 or later, Seattle property-history guidance points users toward the King County Recorder’s Office online search for deed images. Older documents may require King County Archives or other historic research paths.
- Open the Recorder records search page. Start with King County Online Records Search.

- Order certified copies only when needed. Landmark notes that online images are not certified copies. Certified copies can be purchased through the Recorder’s Office process.
Seattle Property History and Archives Research
When the goal is property history rather than tax payment, use both King County and Seattle resources. Seattle City Archives recommends starting with King County Parcel Viewer because it links to legal description, appraised value, recent sales, square footage, building construction details, Assessor reports, GIS information and property tax information.
For older building history, permits, neighborhood changes, historic photos or city records, Seattle City Archives and city permit resources may be more useful than the King County tax statement.
| History Question | Where to Start | What to Collect |
|---|---|---|
| Who owned this Seattle property before? | Landmark Records Search | Grantor, grantee, deed date, recording number, parcel ID and legal description. |
| What is the building age or property detail? | Parcel Viewer | Assessor report, square footage, construction details and sales information. |
| Need older Seattle property-history resources | Seattle City Archives | Historic address, legal description, parcel number, permit clues and neighborhood name. |
| Need old plats or surveys | Washington State Digital Archives | Plat name, survey information, recording year and parcel location. |
GIS Maps, Parcel Boundaries and Map Warnings
King County Parcel Viewer and GIS Open Data are helpful for parcel location, map layers, zoning visibility, address points, selected parcel exports and district/development condition links. They are excellent public research tools, but they are not legal surveys.
- Open King County Parcel Viewer. Use Parcel Viewer to search by address, parcel number or condo name.
- Zoom and click the parcel. Parcel Viewer lets you zoom in and click parcels to get summary information and links to complete property information.
- Use GIS open data for deeper map research. Open King County GIS Open Data if you need datasets or spatial context.

- Use a surveyor for boundary problems. Hire qualified help for fences, easements, encroachments, property-line disputes, construction or legal boundary decisions.
Seattle Permits, Zoning and Building History
