Property Taxes in Washington: Rates, Exemptions, and How They Work (2026)
TL;DR
Washington state has no income tax, making property taxes a key revenue source. The average effective rate is about 0.87%. Property is assessed at 100% of market value. Revenue growth for each taxing district is limited to 1% per year (plus new construction), though voter-approved levies can exceed this. Senior and disabled homeowners may qualify for exemptions or deferrals. Appeals go to the county Board of Equalization within 60 days of the assessment notice, or by July 1, whichever is later.
Assessment
County assessors value all property at 100% of true and fair market value. Physical inspections happen on a 4-6 year cycle, with annual value updates based on market data.
The 1% Revenue Limit
Washington's 1% limit (RCW 84.55) caps the total amount of property tax revenue each taxing district can collect to a 1% increase per year over the prior year's highest lawful levy, plus revenue from new construction. This is a revenue cap, not a rate cap. If property values rise significantly, the rate drops to keep revenue within the limit. Voter-approved levies and bonds are exempt from this cap.
Exemptions
| Program | Benefit | Who Qualifies |
|---|---|---|
| Senior/Disabled Exemption | Exemption from regular levies on portion of value | 61+ or disabled, income under $58,423 (2026, adjusted annually) |
| Senior/Disabled Deferral | Defer taxes until property is sold | 60+ or disabled, income under $75,000 |
| Disabled Veterans | Full or partial exemption | Service-connected disability rating |
