Timeline: The road to an income tax in Seattle

The effort to implement an income tax in Seattle was a months-long effort, working through a series of town halls, committees, and the city council. The council passed an ordinance on July 10, which was signed by Mayor Ed Murray July 21.

Seattle’s progressive income tax is on individuals earning more than $250,000 and families earning more than $500,000, living in Seattle, at a rate of 2.25 percent. Proponents argue it could potentially raise up to $140 million.

Organizations such as the Seattle Transit Riders Union, Neighborhood Action Coalition, and 350 Seattle teamed up with city council members to hold a series of town halls to drum up support for the tax. They argued that it would raise money from the city’s wealthiest residents to cover federal funding cuts under President Trump; hence their slogan “Trump Proof Seattle.”

State law does not allow a progressive income tax, rather, income is legally considered property. All property must be taxed the same for all Washington residents, according to the state constitution. The City of Seattle would then take the case to the state Supreme Court. If the city succeeds, it would change the legal understanding of the state constitution and open the door for a statewide income tax, or for local jurisdictions to implement their own.
