Washington moves toward 9.9% tax on high earners as governor poised to sign

Washington’s Legislature passed a 9.9% income tax on households earning over $1 million, clearing the way to Gov. Bob Ferguson’s desk after a last-minute Republican challenge; the governor has signaled he will sign, and the bill would take effect after revenue begins in 2029 to fund schools, health care, higher education and public safety, with expanded tax breaks for small businesses and low‑income families. Supporters say it corrects a regressive tax code, while opponents warn of constitutional questions and potential impacts on business and capital flight, and amendments were added during passage to clarify language and offset revenue losses.
