Washington state has no income tax. It just passed one for millionaires that could be a model for other states

The bill would tax earnings over $1 million at 9.9%, which could raise billions annually. Expect a big fight from the ‘wealth defense industry.’

People who live and work in Washington state don’t currently pay any income tax. But in a few years, a small group of residents will be subject to one: Washington lawmakers recently passed a bill that would impose a 9.9% tax on income earned above $1 million, which goes into effect on January 1, 2028.
