Establishing a tax on millionaires.

HB 2724 proposes a new tax on Washington residents with annual adjusted gross income of $1 million or more, affecting approximately the top 0.5% of households. The tax revenue would be deposited into the state general fund to support K-12 education, health care, higher education, human services, and the working families' tax credit. Key provisions include exempting sales of family-owned small businesses and real property from the tax, aligning the state definition of taxable income with federal rules (modified for state purposes), and reducing other taxes like sales tax on essential items. The bill aims to make the state tax system less regressive by shifting more burden to high earners while maintaining current tax rates for lower-income residents.
