A secret to the Evergreen State’s success has been that it has no income tax. But Democrats in Olympia are perilously close to enacting a “millionaire tax” of 9.9%. Washington would go from being one of nine states with no income tax to having the fifth-highest rate in the country. The tax has passed both legislative houses and Gov. Bob Ferguson says he’ll sign it. Supporters hope the state supreme court will uphold it, overturning or brushing aside a 1933 precedent under which it is plainly unconstitutional.
