In a marathon legislative showdown that stretched more than a full day, Democrats in Washington state forced through a controversial new tax aimed at high-income earners—despite fierce opposition and warnings about its long-term consequences.
The proposal, commonly referred to as a “millionaire tax,” imposes a 9.9 percent tax on income exceeding $1 million. Supporters argue the measure will raise billions of dollars for new government spending and claim it will make Washington’s tax system more “fair.”
But critics say the bill is something else entirely: a major step toward establishing a state income tax in a place where voters have repeatedly rejected the idea.
Republican lawmakers fought the measure through more than 24 hours of intense debate, introducing numerous amendments and raising concerns that once government gains the power to tax income—even if it begins with the wealthy—it rarely stops there.
For decades, Washington has been one of the few states without a traditional income tax. Opponents of the bill warn that the new policy chips away at that principle and opens the door to broader taxes on working families down the road.
Republicans also pointed out that Washington voters have rejected income tax proposals at the ballot box multiple times. In their view, the current legislation is an attempt to sidestep the will of the people and push through a policy voters have already said no to.
Supporters claim the tax will only affect a tiny fraction of residents—roughly the wealthiest one percent. But critics say targeting entrepreneurs and investors could have serious economic consequences, particularly if high earners choose to relocate to states with friendlier tax climates.
At a time when many businesses are already facing inflation, rising costs, and regulatory pressure, opponents warn that punishing success is exactly the wrong signal to send.
Legal challenges are widely expected if the measure becomes law, as critics argue the policy may conflict with Washington’s constitutional restrictions on income taxes.
For many conservatives in the state, the fight is about more than just one bill. They see it as part of a broader push toward bigger government, higher taxes, and policies that threaten Washington’s economic competitiveness.
And after a bruising 24-hour battle on the legislative floor, they say the debate over income taxes in Washington is far from over.
