Washington Property Tax Law Changes 2026: What Homeowners Need to Know

Updated March 2026

Key Takeaway

Washington has no state income tax, making property taxes a critical revenue source. The state's 1% levy lid limits annual levy increases, and the Senior/Disabled Exemption provides income-based relief (up to 100% exemption) for qualifying homeowners 61+ with income under $58,423. Washington assesses at 100% of market value.

1% Levy Lid

Washington's 1% levy lid limits how much a taxing district's total property tax levy can increase each year (1% plus new construction). Districts can exceed the lid with voter approval ("levy lid lift"). This is a levy cap, not an assessment cap -- your individual assessment can increase by any amount, but the total revenue collected by each taxing district is capped.

Senior/Disabled Exemption: Up to 100%

Washington's Senior Citizens and Disabled Persons Property Tax Exemption is income-based:

Age 61+ or disabled
Income under $58,423 (adjusted annually)
Benefit tiers: partial to full exemption depending on income level
Lowest-income qualifiers pay zero property taxes

This is one of the most generous senior programs in the country. Apply through the county assessor.

Property Tax Deferral

Washington allows seniors 60+ and disabled persons to defer all property taxes as a lien against the home. The deferred taxes accrue interest at 5% (set by statute). The program is available to homeowners with income under $57,000. The state pays your taxes and is repaid when the home is sold.

No Income Tax

Washington's lack of state income tax means property taxes, sales taxes, and the B&O (business) tax carry the revenue burden. This political context limits how much the legislature can reduce property taxes without finding alternative revenue. The state's capital gains tax (enacted 2021, upheld by courts) may provide some relief funding.

60-Day Appeal Window

File petitions with the county Board of Equalization within 60 days of the assessment notice (typically July). If denied, appeal to the Board of Tax Appeals within 30 days of the BOE decision. Washington tracks market value annually, so current comparable sales are your strongest evidence.
