Redmond Property Tax Appeal Guide

At a glance

Redmond's residential market is heavily shaped by Microsoft employment and the broader Eastside tech corridor. Neighborhoods like Education Hill, Overlake, and the areas near Marymoor Park saw compressed inventory and rapid price gains through 2021-2022. Microsoft's hybrid and return-to-office cycles, combined with tech-sector layoffs in 2023, created demand softening that did not uniformly flow through into assessed values. The King County Assessor uses January 1 market data, which means a correction that accelerated through 2023 may still not be fully reflected in 2026 assessed values for some Redmond properties.

How the appeal process works

1. 1

   Review your assessment notice

   King County mails assessment notices on a rolling schedule throughout the year. Find your notice, note the mail date, and compare the assessed value to recent closed sales in your specific Redmond neighborhood. Your 60-day window starts from the notice date.

2. 2

   Find comparable sales

   Search for homes that sold within 12 months of January 1 in your same neighborhood, matched on square footage, lot size, age, and condition. Redmond has meaningful variation between neighborhoods, so comps should be as geographically tight as possible.

3. 3

   File with the King County BOE

   File your petition online or by mail with the King County Board of Equalization. You need your parcel number, current assessed value, and the value you believe is correct. No filing fee. Deadline is July 1, 2026, or 60 days after your notice date.

4. 4

   Present at your BOE hearing

   Hearings are typically 15 to 30 minutes by phone. You present your comparable sales and any condition documentation. The assessor's representative responds. The board decides. Redmond cases often turn on tight neighborhood comps given the city's internal price variation.

5. 5

   Receive the decision

   A written decision arrives within a few months. If the BOE reduces your value, your tax bill is recalculated for the assessment year you appealed. If denied, you can escalate to the Washington State Board of Tax Appeals within 30 days.

Common reasons to appeal

• +Your assessed value reflects the 2021-2022 tech-driven peak while comparable sales have since declined
• +Tech-sector demand softening in your neighborhood has not been captured by the Assessor's model
• +Your home has condition issues, deferred maintenance, or functional limitations not visible in the assessment
• +Comparable sales in your immediate Redmond neighborhood support a lower market value
• +Your property record contains errors in square footage, year built, or finish level
• +The assessment increased more than local sale prices moved in your specific area

Frequently asked questions

Does the city of Redmond handle property tax appeals?

No. Redmond properties are assessed and appealed through King County, not the city. The King County Assessor sets the value. The King County Board of Equalization hears appeals. The city of Redmond has no role in the assessment or appeal process.

How does Microsoft employment affect Redmond property tax assessments?

Tech employment concentrated in Redmond drove rapid price appreciation through 2022. The King County Assessor's model picked up those gains. When demand softened in 2023, the correction did not flow through evenly. Homeowners in neighborhoods where demand fell fastest are most likely to have assessments that outrun current market value.

What Redmond neighborhoods have the most appeal potential?

Neighborhoods closest to the Microsoft campus and those that saw the steepest 2020-2022 appreciation followed by a softer correction are the most likely candidates. Overlake and Education Hill are worth checking. Comparing your assessed value to recent closed sales in your immediate area is the only reliable way to know.

Can I appeal a townhome or condo in Redmond?

Yes. The appeal process applies to all property types assessed by King County, including townhomes, condos, and single-family homes. For condos, comparable sales should be units in the same development or comparable buildings sold near January 1.

What senior exemptions apply to Redmond homeowners?

Washington's senior and disabled persons exemption applies to Redmond properties. Homeowners 61 or older with a combined disposable income under $84,000 (2026 threshold) may qualify. Apply through the King County Assessor's office. FairAppeal can occasionally help with exemption applications too. Email hello@fairappeal.com if you want us to take a look.
