Washington Property Tax 2026: 1% Levy Cap, Senior Exemption and BOE Appeal

Washington is one of the few U.S. states with no income tax — property tax and sales tax carry the revenue load. A statutory 1 percent annual cap on levy growth (I-747, codified into law) limits how fast taxing districts can grow their revenue, but the homeowner's bill can still rise when assessed value outpaces the district average. This 2026 guide explains the 1% cap, the senior exemption income tiers that vary dramatically by county, and the July 1 appeal window.

How Washington Property Tax Works

Washington property tax is assessed at 100% of true and fair value (market value) as of January 1 by each of the 39 county assessors. Tax rates (levies) are set annually by taxing districts: state, counties, cities, school districts, and numerous special districts (fire, library, emergency, hospital, ports).

The tax calculation

The state school levy (Part 1 & Part 2)

Washington collects a state-level property tax dedicated to K-12 schools. Part 1 is the traditional state levy. Part 2 was added by the 2017 McCleary legislation. Combined, they typically contribute $2.20 to $2.70 per $1,000 assessed value to every Washington property tax bill.

The 1% Levy Cap

Initiative 747, approved by Washington voters in 2001 and later statutorily reenacted, caps the annual growth in regular property tax revenue for each taxing district at 1% (or the inflation rate, whichever is less) plus adjustments for new construction, annexations, and state-assessed utility value.

What is capped

Aggregate revenue growth for the district. If your home's assessed value rises 10% but the overall district only grew 3%, then the effective levy rate is rolled back so total revenue grows only 1%. Your individual bill might rise more than 1% because value within the district is redistributed.

What is NOT capped

• Voter-approved special levies (excess levies for schools, emergency services, library)
• Voter-approved levy lid lifts (see below)
• Bond levies for voter-approved debt

Levy Lid Lift

Taxing districts can ask voters for a "levy lid lift" that allows revenue to grow above the 1% cap for a specific period (typically 4-6 years). Requires simple majority. Many school districts, library districts, and fire protection districts rely on regular lid lifts to keep up with actual service costs.

Senior and Disabled Persons Exemption

Washington offers a robust senior and disabled exemption under RCW 84.36.381, but the eligibility thresholds are set by county based on the county median household income. This creates substantial variation.

Statewide eligibility framework

• Age 61 or older, OR retired from regular gainful employment due to disability
• Primary residence owned and occupied
• Annual household income below county-specific thresholds (tiered)

Benefit levels (three income tiers)

The exemption has three tiers, each providing increasing relief:

• Lowest tier: exempt from all excess levies (voter-approved special levies)
• Middle tier: exempt from excess levies PLUS partial exemption from regular levies
• Highest tier: exempt from excess levies PLUS greater regular levy exemption; assessed value "frozen" at prior year level

County-specific income thresholds (2026)

Check with your county assessor for exact 2026 thresholds. Even when phased out of the full exemption, many seniors still qualify for partial benefits at higher incomes.

Deferral Program (alternative)

For seniors with income too high for the exemption, Washington also offers a senior deferral: unpaid tax accrues at 5% simple interest and is repaid when the property is sold or transferred. Higher income cap than the exemption (currently around $67,000 household income for 2026).

Application

File with your county assessor. Annual recertification usually required. Income verified against federal tax return.

Other Exemptions and Programs

Disabled Veteran Exemption

Veterans with 80%+ service-connected disability receive the same senior/disabled exemption benefits — income tiers apply but age is not required. 100% disabled veterans have priority processing.

Widow/Widower of Veteran Exemption

Surviving spouses of eligible disabled veterans maintain the exemption as long as they do not remarry and continue to occupy the property.

Current Use Taxation

Agricultural, timber, and open-space land enrolled in current use programs is valued based on use rather than market value — often 80-95% reduction in assessed value. Conversion to non-qualifying use triggers a 7-year rollback tax.

Historic Property Tax Exemption

Properties listed on state or National Register of Historic Places may qualify for tax reduction on rehabilitated portions.

Appealing Your Assessment

Washington appeals start at the County Board of Equalization.

Step 1: Contact the assessor

Review the Notice of Change in Value sent by the county assessor. Many disputes resolve through informal conversation with the assessor's staff.

Step 2: County Board of Equalization (BOE)

File with the BOE by July 1 of the tax year (or 30 days after the assessor's notice of denial, whichever is later). Filing is free. Present evidence at the BOE hearing within a few months.

Step 3: State Board of Tax Appeals (BTA)

If dissatisfied with the county BOE, appeal to the State BTA within 30 days of the BOE decision. Formal procedure; may represent self or use attorney.

Step 4: Superior Court

BTA decisions may be appealed to Superior Court on the record.

Evidence that wins

• Recent arm's-length sale below assessed value
• Comparable sales within 12-18 months of January 1 of the assessment year
• Independent fee appraisal
• Physical attribute errors on the property record

Payment Schedule

Washington property tax for the calendar year is billed in two installments:

• First half: due April 30
• Second half: due October 31

Total annual payment option available: pay full year by April 30 in most counties. Delinquent tax accrues 12% annual interest plus penalty. After 3 years of delinquency, the county treasurer may initiate tax foreclosure proceedings.

Frequently Asked Questions

What is the 1% property tax cap in Washington?

Initiative 747 (2001) caps annual growth in regular property tax revenue for each taxing district at 1% (or inflation, whichever is less) plus adjustments for new construction. It does not cap individual bills — district revenue is limited, but individual properties can see larger changes. Voter-approved levy lid lifts can exceed the 1% cap for specific periods.

Who qualifies for the Washington senior property tax exemption?

Homeowners age 61+ or retired due to disability, with household income below county-specific tiered thresholds (for example, King County $60,000 to $84,000 in 2026; Spokane $36,000 to $50,000; Pierce $46,000 to $64,000). Three benefit tiers provide increasing relief — from exemption from excess levies only, up to full regular-levy exemption with value freeze. File annually with county assessor.

When is the Washington property tax appeal deadline?

File with the County Board of Equalization by July 1 of the tax year (or 30 days after the assessor's denial notice, whichever is later). Escalation to State Board of Tax Appeals within 30 days of BOE decision, then to Superior Court on the record.

Does Washington have a property tax for schools?

Yes. The state collects a statewide school levy (Part 1 and Part 2 under the 2017 McCleary legislation) typically $2.20 to $2.70 per $1,000 assessed value, dedicated to K-12 school funding. This is in addition to local school district operating and capital levies, which also appear on your bill.

What is a senior deferral in Washington?

An alternative to the exemption for seniors with income too high to qualify for the exemption. Unpaid property tax accrues 5% simple interest and is repaid when the property is sold or transferred. Income cap typically around $67,000 household income for 2026. Check with your county assessor for current thresholds.
