WA HB2024

Creates a primary residence property tax exemption from the state levy equal to the greater of $100,000 assessed valuation or 60% of the county median residential assessed value, beginning with taxes collected in 2028

Exemption applies only to the state property tax levy, not local taxing district levies, and requires the residence be occupied as the claimant's principal place of residence for at least 184 days per year

Applications must be filed with the Department of Revenue by April 1st of the year prior to receiving the exemption; claimants may only claim the exemption on one residence per calendar year

Establishes a Primary Residence Property Tax Exemption Administration Account to distribute $5 per application to counties for administration costs ($10 per application in 2026-2027)

Takes effect January 1, 2026, contingent on voter approval of a constitutional amendment (Senate Joint Resolution S-0811/25) authorizing the residential property tax exemption
