WA Income Tax Repeal: No on I-645 Campaign Warns of $13 Billion Revenue Loss

October 17th, 2026· 0:42

Washington voters will decide on November 3 whether to repeal the state's new 9.9% income tax through Initiative 645, and opponents of the repeal are warning of major consequences for state revenue. The No on I-645 campaign claims repealing the income tax would eliminate approximately $13 billion in projected state revenue that could otherwise support healthcare, education and other government priorities. In a campaign advertisement, opponents also argue that Washington has an upside-down tax system, claiming working families pay three times more than the wealthiest residents relative to their income. The campaign's message highlights the growing debate over Washington's income tax, tax fairness, government spending and the potential consequences of repealing the measure. As Washington's November election approaches, voters face competing arguments about state revenue, public services and the economic impact of income taxes.
