Seattle Tacoma, WA, October 14, 2026 —
Washington voters will decide in November whether to repeal or uphold a new state tax described as a 9.9% levy on household income exceeding $1 million. The measure, Initiative 645, was placed on the ballot by opponents of the tax.
The tax is scheduled to take effect in 2028. The ballot question will give voters a choice over whether it remains in place, but the information provided does not specify the exact election date or the year in which the November vote will occur.
Details about how the tax would be calculated, which households would be covered, or how much revenue it is expected to raise were not provided. The names of the measure’s supporters and opponents were also not included. No campaign statements or arguments from either side were available in the information provided.
Initiative 645’s official ballot wording and the vote threshold required for it to pass were not specified. The measure’s placement on the ballot means voters will decide the tax’s fate, but no outcome is yet available. The tax’s planned 2028 start date is the only implementation timing given.
For now, the central question before voters is whether to keep the 9.9% tax on household income above $1 million or repeal it. Further details about the measure and the arguments surrounding it were not included in the available summary.
