Yakima County, home to Yakima and 256k Washingtonians, operates under Washington State's distinctive levy-based property tax system. Washington uses 100% assessment ratio (assessed at true and fair market value) and total tax combines state school + local school + county + city + special districts (typically expressed as dollars per $1,000 of AV). Initiative 747 (passed by voters in 2001) caps regular levy revenue growth at 1% per year per district.
How the bill is built
Washington's property tax calculation has two main steps. Step 1: Assessed Value. The Yakima County Assessor reassesses property annually at true and fair market value. Step 2: Apply combined rate. Total rate combines all overlapping districts (state school + local schools + county + city + EMS + library + fire + park + flood control + cemetery, depending on location). Yakima's combined rate is approximately 10.00 per $1,000 of AV. Tax = (AV × combined rate) / 1,000. Yakima's effective rate of 1.00% reflects this calculation.

Senior/disabled exemption and excess levies for 2026
Washington's homeowner tax relief is concentrated in a single income-tested Senior Citizens and Disabled Persons Property Tax Exemption (covering both seniors AND disabled veterans). Initiative 747's 1% revenue cap creates structural rate stability for ALL property owners regardless of exemption status.
Senior Citizens and Disabled Persons Property Tax Exemption
Washington's exemption combines a partial reduction of regular property taxes with a freeze on assessed value at the time of qualification. Income limits (2026) are tiered:
- Income under $30,000: Full exemption from regular levies + AV freeze
- Income $30,000-$35,000: 65% reduction in regular levies + AV freeze
- Income $35,000-$45,000: 35% reduction in regular levies + AV freeze
Eligibility: must be 61+ OR disabled OR a disabled veteran with 80%+ service-connected disability. Apply with the Yakima Assessor office. Once qualified, the AV freeze locks in your assessed value as of the qualification year — even if market values rise substantially, your assessed value (and tax base) remains constant. The exemption applies to regular levies only; voter-approved excess levies (typically school M&O) are still owed.
Property Tax Deferral Program (seniors 60+)
Washington offers a Property Tax Deferral Program separate from the senior exemption — eligible seniors 60+ with income under ~$57K can defer property tax payments (with state-paid interest) until the property is sold or transferred. The deferred amount becomes a lien on the property. This is particularly valuable for cash-poor / asset-rich seniors who want to remain in their homes.
Excess Levies (school M&O)
Washington's regular levies are capped at 1% annual revenue growth per district under Initiative 747 (2001). However, voter-approved excess levies — primarily school maintenance and operations levies — are exempt from the 1% cap. Excess levies typically run 2-4 year terms and require 60% voter approval. School excess levies often dominate the combined tax bill (typically 30-50% of the total) — when these levies expire and are renewed (or fail), bills can change significantly. Watch for ballot measures.
Appealing your assessment
Washington's appeal process runs through the County Board of Equalization (BOE). Homeowners file a Petition for Review with the BOE within 60 days of the change of value notice (or by July 1, whichever is later). The BOE holds hearings — homeowners can present comparable sales, recent appraisals, or independent appraiser testimony. BOE decisions can be appealed to the Washington State Board of Tax Appeals within 30 days; from there to Superior Court. Most Washington counties reassess annually under the State Department of Revenue's revaluation cycle.
