This proposed constitutional amendment would establish an additional 4% state income tax on that portion of annual taxable income in excess of $1 million. This income level would be adjusted annually, by the same method used for federal income-tax brackets, to reflect increases in the cost of living. Revenues from this tax would be used, subject to appropriation by the state Legislature, for public education, public colleges and universities; and for the repair and maintenance of roads, bridges, and public transportation. The proposed amendment would apply to tax years beginning on or after January 1, 2023.
