Olympia — Gov. Bob Ferguson signed Senate Bill 6346 on March 30, enacting a 9.9% income tax on households earning more than $1 million; the law schedules collections to begin in 2029 and is projected to raise roughly $3 billion annually from approximately 21,000 filers. The signing prompted immediate legal and political responses this week: the Citizen Action Defense Fund announced litigation citing a 1933 state precedent, opponents are organizing a November ballot referendum, and officials say the revenue will fund schools and targeted tax relief for lower-income residents and small businesses.
