Exemptions & appeals
View exemption application (opens in a new tab)Senior relief
Washington senior/disabled property-tax reduction is administered by the county assessor for qualifying owners age 61+ or persons with disabilities who meet ownership, occupancy and income requirements; Yakima County directs applicants to its Treasurer/Tax Information and Assessor pages and the Washington Department of Revenue application materials.
Valuation limits
Washington has no individual-parcel annual valuation cap verified for these counties. County assessors value taxable property at 100% of true and fair market value. The 2026 regular levy limit generally limits each taxing district's levy growth to 1% (101% limit factor), but that is a taxing-district revenue limit, not a cap on an individual property's assessed value or tax bill; new construction, improvements and voter-approved levies may be treated differently.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
