Legislative Approval of the Income Tax Bill
On March 10, 2026, the Washington State House of Representatives approved a significant income tax bill targeting households earning over $1 million annually. This legislation, known as Senate Bill 6346, passed with a vote of 51-46 after extensive debate lasting over 24 hours. The bill now awaits concurrence from the Senate on amendments before being sent to Governor Bob Ferguson, who has expressed his intent to sign it into law. If enacted, this tax would mark the first income tax on wages in Washington in nearly a century.
The proposed tax imposes a 9.9% levy on adjusted gross household income exceeding $1 million, set to take effect on January 1, 2028. It is projected to generate between $3.5 billion and $4 billion annually from approximately 21,000 filers, with the income threshold adjusted for inflation every two years.
Political Dynamics and Debate
The passage of the bill saw intense opposition from Republican lawmakers, who argued that the income tax is unconstitutional under Washington state law, citing a 1933 Supreme Court ruling that invalidated a similar measure. They expressed concerns that this tax could eventually extend to lower-income households. Despite these objections, Democrats maintained their stance, emphasizing the need for a more equitable tax system that alleviates the tax burden on lower-income residents.
Democratic Representative Natasha Hill characterized the vote as "epic," asserting that the tax is a progressive step toward a fairer tax code. Conversely, Republican Representative Matt Marshall criticized the proposal, stating he could not support it in good conscience.
Implications and Future Challenges
The income tax bill is expected to face legal challenges and potential ballot initiatives aimed at overturning it. Opponents would need to gather over 300,000 signatures to place the issue before voters, a significant hurdle given the historical context of income tax proposals in Washington. Previous attempts to introduce an income tax have been met with resistance, including a 2010 initiative that was rejected by 64% of voters.
In addition to the income tax, the legislation includes various tax changes, such as exemptions for certain businesses and tax breaks for low-income families. The revenue generated is earmarked for expanding the Working Families Tax Credit and supporting early childhood education programs.
Criticism and Opposition Perspectives
Critics of the income tax have voiced concerns about its potential economic impact, arguing that it could deter investment and job creation in the state. Republican lawmakers have called for a more comprehensive review of the tax implications, suggesting that the bill's passage at the end of a short legislative session undermines thorough scrutiny.
Representative Ed Orcutt described the day of the vote as a "dark day in Washington's history," reflecting the sentiments of those opposed to the tax. They argue that the tax structure should be uniform and not disproportionately target high earners.
