Legal Challenge to Washington's Millionaires Tax Sparks Controversy
4/10/2026, 7:12:42 AM
Overview of the Legal Challenge
Washington State's newly enacted "millionaires tax," which imposes a 9.9% tax on income exceeding $1 million, is facing its first legal challenge. The lawsuit, filed by the Citizen Action Defense Fund in Klickitat County Superior Court, argues that the tax violates the Washington Constitution and longstanding legal precedents. The challenge is spearheaded by former Washington Attorney General Rob McKenna and former state Supreme Court Justice Phil Talmadge, who contend that income is classified as property under state law, and property taxes must be uniform and limited.
Key Figures and Organizations
The legal team opposing the tax includes:
- Rob McKenna: Former Washington Attorney General and lead attorney for the plaintiffs.
- Phil Talmadge: Former state Supreme Court Justice, also part of the legal team.
- Jackson Maynard: Executive Director of the Citizen Action Defense Fund, which is backing the lawsuit.
The plaintiffs include Ben and Lauren Petter, who are expected to be affected by the tax, along with various organizations such as the Ethnic Chamber of Commerce Coalition and the Building Industry Association of Washington.
Official Statements & Responses
Rob McKenna stated, “This law disregards both the plain language of the Constitution and decades of consistent Supreme Court precedent. We are confident the courts will strike it down.” Senate Majority Leader Jamie Pedersen, a proponent of the tax, welcomed the legal challenge, asserting that it provides an opportunity to clarify the legality of a progressive tax in Washington. He remarked, “One of the main points of bringing the bill was to put this question back in front of the Supreme Court."
Criticism & Opposition
Opponents of the tax argue that it sets a precedent for a broader income tax system in Washington, which has historically rejected such measures. Mike Sotelo, president of the Ethnic Chamber of Commerce Coalition, expressed concerns about the tax's impact on small businesses, stating, “The tax poses another threat to their economic survival.” Meanwhile, advocacy group Invest in Washington Now criticized the lawsuit, claiming it seeks to protect wealthy individuals from contributing fairly to community needs.
Timeline of Events
- March 30, 2026: Governor Bob Ferguson signs Senate Bill 6346, establishing the millionaires tax.
- April 9, 2026: The lawsuit is filed in Klickitat County Superior Court.
- April 30, 2026: The state Supreme Court is scheduled to discuss a separate referendum that could allow voters to repeal the tax.
What's Next
The case is expected to progress slowly through the courts, with a potential hearing in Klickitat County by late summer. Talmadge speculated that the issue may not reach the state Supreme Court until after the November elections, when five justices are up for reelection. The outcome of this legal battle could significantly influence Washington's tax structure, with collections from the tax slated to begin in 2029 if upheld.
Conflicting Reports & Gaps
There are differing opinions on the potential economic impact of the tax. While proponents argue it will fund essential services and target a small percentage of households, critics fear it could lead to broader taxation. Additionally, the state Supreme Court's previous rulings on income taxation remain a contentious point, with historical precedents cited by both sides.
