Seattle council has voted for an income tax on highly paid residents (2.25% on everything above $250k), but income taxes are nominally unconstitutional in Washington State. It's been working its way through the state courts for years. So far the lower courts have ruled that an income tax may be constitutional (this would be a first, in Washington) ... but only if the rate is equal for all earners (So the Seattle tax still fails).
