Washington lawmakers are advancing Senate Bill 6346, which would impose a 9.9% tax on income over $1 million starting in 2028. While framed as a targeted measure, this proposal marks a major shift in Washington’s tax structure — one that could open the door to broader income taxation in the future.

Washington voters have repeatedly rejected statewide income taxes. Changing course now, without a constitutional safeguard limiting the tax strictly to millionaires, risks eroding long-standing protections and creating uncertainty for residents and employers alike.

There are also real economic concerns. High earners are highly mobile. If even a small number relocate, projected revenue could fall short, leaving lawmakers to search for new sources of funding. Structural tax changes should be stable, predictable, and broadly supported — not rushed forward in a divided climate.

Washington needs solutions that strengthen education and healthcare without risking long-term competitiveness or expanding income taxation beyond what voters have approved.

We are calling on the Washington State Legislature to halt Senate Bill 6346 and pursue alternative funding strategies that protect economic stability and respect voter intent.

Sign this petition to oppose a new income tax in Washington state.
