Recent polling shows Washington voters oppose repealing the 9.9% tax on household income above $1 million by a 57-35 margin when shown the required ballot fiscal impact statement warning of reduced funding for K-12 education, higher education, and human services. That statement remained on the ballot after the state Supreme Court split 4-4 in September, widening the gap compared to versions without the language. Initiative 645, which would repeal the tax enacted in March 2026 and bar future income taxes, faces opposition from unions and Democratic leaders citing projected annual revenue exceeding $3 billion starting in 2029. Supporters argue it opens the door to broader taxation. Ballots begin mailing ahead of the November 3 vote, with campaign spending and legislative races amplifying the measure. Trader pricing reflects these polling dynamics and procedural advantages for retention.
