Concerning property tax exemptions for veterans with disabilities.

SB 5398 creates property tax exemptions for Washington veterans with severe service-connected disabilities and their surviving spouses. It allows veterans receiving VA compensation for a combined disability rating of 80% or higher (or total disability) to qualify for tax relief, along with surviving spouses aged 57+ who meet income requirements. The exemption reduces or eliminates property taxes based on income thresholds: full exemption for lowest-income veterans (threshold 3), and partial exemption covering up to $70,000 of home value for moderate-income veterans (threshold 2), or up to 60% of home value (minimum $60,000) for highest-income eligible veterans (threshold 1). The bill adjusts tax calculations for income changes like retirement or spouse loss, and maintains eligibility during cost-of-living increases to social security benefits.
