Washington State’s Proposed “Millionaires Tax” and the Upcoming Vote
By Drooid · · How we work
Core Proposal and Expected Revenue
Washington voters will soon decide on Initiative X, a statewide “millionaires tax” that would levy a 9.9 percent rate on income above $1 million per year. State officials estimate the measure could generate more than $3 billion in annual revenue, which proponents argue would help address the state’s persistent fiscal shortfalls.
Political Opposition and Arguments
Republican leaders, including former U.S. Representative Jaime Herrera Beutler, contend the tax will discourage wealthy entrepreneurs from remaining in Washington and could eventually expand to a broader income tax affecting all residents. Critics of the initiative also support a separate referendum that would prohibit future state leaders from imposing any income taxes.
Related Tax Initiatives on the West Coast
The Washington vote coincides with parallel tax debates in California, where voters are considering both a “millionaire tax” and a “billionaire tax.” California’s proposals include making permanent a temporary income-tax increase for couples earning at least $743,000 annually and establishing a wealth tax on individuals with $1 billion or more in assets. Both states’ measures have drawn strong reactions from affluent residents, educators, and health-care groups concerned about potential budget impacts.
Projected Impact and Fiscal Context
Supporters argue that the $3 billion-plus revenue stream would provide a stable funding source for public services and reduce the need for cuts or borrowing. Opponents warn that higher taxes on high earners could trigger capital flight, eroding the tax base and ultimately shifting the burden to a broader population. The outcome of Washington’s November ballot will signal voter appetite for progressive taxation in a state that has historically relied on sales and property taxes rather than income taxes.
