Redmond Property Tax Database
Redmond property tax records are managed by King County, which handles both assessment and tax collection for all real and personal property in the city. The King County Assessor values Redmond parcels each year, and the King County Treasury operations office bills and collects taxes. You can look up assessed values, pay taxes online, and review your property history through the county's eReal Property system. Taxes in Redmond are due in two installments. The first half is due April 30 and the second half is due in early November. This page covers the main tools and offices you need to manage your Redmond property tax records.
Redmond Overview
King County Assessor and Redmond Property Values
The King County Assessor is responsible for valuing all Redmond properties and administering tax relief programs. The office provides detailed information on how to appeal a property value to the King County Board of Equalization. Contact information for appraisers and exemption specialists assigned to Redmond is available on the Assessor's website. You can reach the Assessor at 206-296-7300 or Assessor.info@kingcounty.gov.
Residential appraisers in King County use two primary valuation methods. The sales comparison approach looks at recent sales of similar properties. The cost approach estimates the replacement cost of structures, subtracts depreciation, and adds land value. Your final tax is based on your assessed value and the total taxable value of all property in your community. An increase in your assessed value does not always mean a dollar-for-dollar increase in your tax bill.
The 2026 Physical Inspection Areas map on the Assessor's website shows which Redmond neighborhoods are scheduled for field review by residential appraisers. The Assessor also maintains a Housing Availability Dashboard with data on housing supply and affordability across King County. Seniors, disabled veterans, and disabled persons can apply for property tax exemptions through the Assessor's office if they meet income and eligibility requirements.
The King County Assessor's portal lets Redmond property owners check assessed values, exemption programs, and appeal options.
The Assessor's website is your starting point for understanding how your Redmond property was valued and what relief programs may apply to you.
Search Redmond Property Records with eReal Property
The King County eReal Property system is the primary online tool for searching Redmond property tax records. You can search by property address to find the parcel information and tax account number. The system displays property characteristics, assessed valuations, tax account status, and ownership details for any King County parcel including those in Redmond.
Under Washington State law, RCW 42.56.070(9) prohibits using lists of individuals from the eReal Property system for commercial purposes. You must agree to that restriction before accessing data. The King County Department of Assessments also disclaims accuracy and warns that any person relying on the data does so at their own risk. Verify critical information from other sources before making financial or legal decisions.
Property owners can register to receive assessment notices by email through the Assessor's website. Tax appeals can be filed online through the eAppeals system. The site also links to levy rate reports, tax relief programs, and exemption and deferral information for Redmond and other King County communities.
The eReal Property system gives Redmond owners online access to parcel data, assessed values, and tax account details.

City of Redmond Property Tax Information
