This bill replaces RCW 84.36.383 with new statutory text (Sec. 1) that provides definitions and income threshold formulas for a property tax exemption program described in the title as expanding access for seniors, people retired due to disability, and veterans with disabilities. It also adds Sec. 2 making the act apply to taxes levied for collection in 2027 and thereafter, and Sec. 3 stating that RCW 82.32.805 and 82.32.808 do not apply to this act. The new Sec. 1 defines terms used for the exemption program, including accessory dwelling unit, combined disposable income (the claimant’s disposable income plus that of a spouse, domestic partner, and cotenants, less specified healthand care-related payments), cotenant, county median household income (as published by the Office of Financial Management), department (Department of Revenue), disability (defined by reference to 42 U.S.C. §423(d)(1)(A) as of specified dates), disposable income (based on federal adjusted gross income with specified add-backs and exclusions), principal place of residence (occupied more than six months a year), real property (including certain mobile homes), and residence (single-family dwelling with specified land limits). The section establishes three tiered income thresholds (Income threshold 1, 2, and 3) with base dollar amounts for periods prior to 2020 and schedules that tie thresholds in later periods to specified percentages of county median household income, with adjustments every three years beginning August 1, 2023, as referenced to RCW 84.36.385(8). The bill identifies the Department of Revenue and the Office of Financial Management as involved agencies and cites numerous related state and federal statutes. The provided text contains definitions and threshold mechanics but does not include the substantive eligibility criteria, application process, benefit calculations, or procedural rules for the exemption program; the referenced adjustment mechanism in RCW 84.36.385(8) and any other amended or new sections beyond Secs. 1–3 are not included in the extracted material, so those parts of the program change are unclear from the provided facts.

If enacted, the law raises and ties the income limits used to determine eligibility for the property tax exemption for seniors, people retired for disability, and veterans with disabilities to a percentage of county median household income, with higher percentages phased in by 2027 and adjusted every three years. That means, beginning with taxes levied for collection in 2027, a larger number of low‑ and moderate‑income homeowners in many counties are likely to qualify for partial or full property tax relief, especially where local median incomes have risen; however eligibility will still be based on combined disposable income that includes spouses, domestic partners, and cotenants, so household composition could make some people newly eligible or ineligible. The practical effects will fall mainly on qualifying homeowners who can expect lower property tax bills and on local taxing districts that may see reduced property tax revenue and thus face pressure to adjust budgets or levy rates. The Department of Revenue will have to apply the new definitions and thresholds and the Office of Financial Management will provide the county median income data used to set limits, creating some administrative work and potential costs. The bill text here does not show how the exemption amount is calculated, how applications are processed, or the size of likely revenue impacts, so the exact fiscal consequences and implementation details remain unclear.
