Washington voters will decide Initiative 26-645 on November 3. The measure would repeal the state's newly enacted 9.9% tax on annual individual income above $1 million and would go further by prohibiting state and local governments from imposing taxes on individual income, receipt of individual income, or taxes measured by individual income. The tax is scheduled to begin in 2028 if it remains in law. The initiative therefore asks voters both about the current high-income tax and about whether Washington should restrict future use of individual-income-based taxation more generally. This vote is broader than whether one tax rate is too high or too low. It also decides how much freedom future state and local governments should have to use income as a tax base. Voters should weigh both the immediate tax and the long-term restriction.
Should Washington preserve, repeal, or more narrowly revise its new tax on annual individual income above $1 million?
