Washington Trucker Sues State Over New 9.9 Percent Millionaires Income Tax

A Washington trucking company owner is suing the state over a new 9.9 percent "millionaires" income tax. The lawsuit was filed recently in state court and challenges the law's reach and effect on small businesses and pass-through income. The plaintiff says the tax hits small firms that report owner income on personal returns and could raise costs for family-owned trucking operations.

Supporters of the measure argue it raises revenue for public services, while opponents call it burdensome to job creators and small businesses. Activists and commentators have discussed the case on social media, framing it as a test of tax fairness and of how the state treats small-business income. The lawsuit's outcome could shape enforcement and future challenges to Washington's top marginal tax and influence state business climate debates.
