In a move that has sparked debate, the Washington state legislature recently passed a new 'millionaires tax' law that will impose an income tax on the highest earners in the state. The legislation was signed into law by Governor Bob Ferguson as part of a broader package of bills addressing immigration enforcement and other policy priorities.

Why it matters

The 'millionaires tax' law is seen by supporters as a way to generate additional revenue for social services and programs, while critics argue it unfairly targets the wealthy and could drive high-income residents out of the state. The passage of this law also comes amid an ongoing debate around immigration enforcement in Washington, adding another layer of complexity to the political landscape.

The details

The new 'millionaires tax' law will impose a 5% tax on individuals with annual incomes over $1 million, or couples filing jointly with incomes over $2 million. The revenue generated from this tax is intended to fund various social programs and initiatives, though the specific allocation of funds has been a point of contention. Proponents argue the tax is a necessary step to address income inequality and fund important public services, while opponents claim it will drive wealthy residents to leave the state.

  • The 'millionaires tax' law was signed by Governor Bob Ferguson on April 6, 2026.
  • The new tax will go into effect on January 1, 2027.
