WA HB1004

Increases the personal property tax exemption from $15,000 to $50,000 of true and fair value for taxable personal property owned by individuals

Expands eligibility from "head of a family" to any "person" liable for assessment and taxation, removing previous restrictions tied to surviving spouses, pension recipients, or age requirements

Requires claimants to attest under penalty of perjury that their taxable personal property is under $50,000 or provide a complete list if exceeding that amount, and certify they are claiming only one exemption statewide per calendar year

Exemption does not apply to private motor vehicles or mobile homes (those over 35 feet long or 8 feet wide)

Takes effect January 1, 2026, contingent on voter approval of a related constitutional amendment (House Joint Resolution H-0049/25)
