Advocates of an income tax last year managed to collect signatures to place one proposal on the ballot in the city of Olympia. When voters rejected the idea, they took their campaign to the city of Seattle — where the council voted May 1 to direct staff to come up with a detailed proposal. Though a municipal income tax is certain to face a legal challenge, advocates make no secret of the fact that their plan is to put the issue before the state Supreme Court, which they hope will overturn its 1933 ruling declaring an income tax to be unconstitutional.

The (Tacoma) News Tribune, Oct. 16, 2016: How an Olympia ballot measure could pave the way for a statewide income tax

Regarding last year’s unsuccessful income-tax ballot measure in the city of Olympia: “…The measure, which would levy an income tax on Olympia residents whose household income exceeds $200,000, is likely to end up in the courts if it passes. A legal challenge could give the state Supreme Court a chance to reverse its 1930s decisions that struck down graduated state income taxes as unconstitutional.”
