As Washington Gets an Income Tax, the Fight to Overturn It Begins
The 9.9% tax targets about 21,000 households earning over $1 million, expected to raise $3 billion annually for tax credits and social programs, supporters say.
- On Monday, March 30, 2026, Washington Democratic Gov. Bob Ferguson signed legislation creating a 9.9% income tax on households earning above $1 million annually, marking the first such tax in nearly a century.
- Supporters view the tax as a way to reengineer a regressive tax code that forces lower-income residents to pay an outsized share of earnings. Proceeds will fund the Working Families Tax Credit and Fair Start for Kids Act.
- The tax targets an estimated 21,000 filers, generating around $3 billion annually starting in 2029. The Citizen Action Defense Fund immediately announced plans to sue, arguing the levy violates Supreme Court precedent from 1933.
- Rob McKenna, a former state attorney general, will lead the litigation against the tax. Opponents debate whether to pursue a referendum requiring roughly 200,000 voter signatures by June 10 to qualify for the November ballot.
- Brian Heywood of Let's Go Washington argues for gathering signatures this year, saying "it's crazy to wait," though some strategists recommend delaying until 2027. An initiative to the Legislature would require at least 308,911 signatures by July 2.
