As Washington gets an income tax, the fight to overturn it begins
Come Monday, Washington is expected to have a state income tax on the books for the first time in nearly a century.
Then what?
A legal challenge certainly, maybe two. A ballot battle as well, its timing less certain.
Opponents of the much-debated 9.9% tax on households with incomes above $1 million a year are honing legal and electoral strategies to invalidate and repeal legislation that Gov. Bob Ferguson is expected to sign Monday.
Their specific tactics will become public in the coming days. It’s unlikely any will surprise those engaged in the spirited discourse on the controversial “millionaires’ tax” since its emergence last fall.
