Court battle set to begin over WA's new income tax

Opponents of Washington’s new income tax law plan Thursday to formally launch their legal challenge to the constitutionality of the controversial statute.

Attorneys and plaintiffs have scheduled a 10 a.m. news conference to discuss details of the complaint and where the lawsuit will be filed. It will stream live on TVW.

Former state attorney general Rob McKenna, former state Supreme Court justice Phil Talmadge and Jackson Maynard, executive director of the Citizen Action Defense Fund, are expected to lead the litigation.

This will mark the start of a much-anticipated legal brawl on the law. Dubbed the “millionaires’ tax” by backers, it imposes a 9.9% tax on household wage earnings above $1 million.
