Washington voters face Initiative 645 on the November 3, 2026 ballot, which would repeal the 9.9% tax on household income above $1 million enacted by the Democratic-controlled Legislature and signed by Governor Bob Ferguson in March 2026. The measure, backed by Let’s Go Washington after collecting over 500,000 signatures, would eliminate projected annual revenue exceeding $3 billion starting in 2029 that funds education, small-business relief, and working-family credits. Opponents, including the governor and labor groups, have launched coordinated campaigns highlighting these benefits and warning of broader fiscal impacts. Trader consensus against repeal reflects the state’s recent pattern of sustaining targeted high-earner taxes amid organized opposition and the limited electorate affected.
