Washington House advances 9.9% tax on top earners, prompting business concern

The Washington House passed SB 6346 to levy a 9.9% personal income tax on earnings above $1 million, projecting roughly $3.5 billion in annual revenue starting in 2029. Supporters frame it as tax fairness to offset a regressive system, while critics warn it could erode Washington’s business climate; high-profile concerns, including Howard Schultz’s relocation to Miami, amplify the debate. The measure now moves to the Senate and governor as the session nears its close.
