Establishing an income tax on individuals with Washington taxable income over $1,000,000 per year and households with income over $2,000,000 per year.

HB 2738 would impose a 9.9% income tax on Washington residents with taxable income exceeding $1 million annually, applying to individuals (not households) with income over this threshold. The tax requires prior passage of a constitutional amendment and would generate revenue to fund public defense programs (7%) and state tax relief initiatives (93%), including sales tax relief and working families' credits. It defines "Washington taxable income" through modifications to federal adjusted gross income, with credits available for taxes paid to other states or business taxes. The bill, referred to the Finance Committee after its first reading on February 19, 2026, remains pending.
