Washington’s Tax REVOLUTION: Millionaires Targeted

Washington Democrats just pushed a first-of-its-kind “millionaire” income tax through Olympia, setting up a legal showdown that could crack open the door to a broader state income tax.

Story Snapshot

Washington’s Democrat-controlled Legislature passed a 9.9% tax on income above $1 million, sending it to Gov. Bob Ferguson’s desk.
The measure is designed to raise more than $3 billion annually starting in 2029, with the tax taking effect in 2028.
Supporters argue the money will stabilize budgets and expand programs like school meals, child care, and tax credits.
Opponents warn the proposal disrupts Washington’s long-standing tax structure and will invite court fights and future expansion.

What Democrats Passed—and When the Bill Comes Due

Washington lawmakers approved a 9.9% tax on “Washington taxable income” above $1 million, following marathon floor debate in the House and a late-session Senate vote. The bill, SB 6346, was moved to Democratic Gov. Bob Ferguson’s desk with the expectation of a signature after amendments were adopted. The new tax is scheduled to take effect on Jan. 1, 2028, with first payments due in April 2029.

Democrats framed the measure as a way to close multi-billion-dollar budget gaps while protecting popular services. Multiple reports describe the projected revenue as more than $3 billion per year beginning in 2029, with allocations aimed at core spending such as K-12 education, health care, and higher education. The legislation also reflects negotiated add-ons, including expansions tied to school meals, child care, and other targeted credits or exemptions that backers argue address affordability pressures.

The Real Flashpoint: Washington’s Constitution and the 1933 Precedent

The fight is not only about dollars; it is about whether Washington can legally impose an income tax under current interpretations of state law. Washington has long relied on sales, property, and Business & Occupation taxes instead of a broad income tax. A key barrier has been a 1933 Washington Supreme Court ruling that treated income as property for constitutional purposes, effectively blocking an income tax structure unless that precedent changes or the constitution is amended.

Axios reported the new law is expected to face significant challenges, including litigation and potential ballot efforts. Democrats are signaling confidence that today’s courts might revisit the 1933 framework, while critics see that posture as the point—using a “millionaires-only” design to test the legal wall and, if the wall falls, normalize income taxation as a permanent feature of state government. On the right, that concern is intensified by the simple reality of budget politics: once a new revenue stream exists, pressure builds to widen it.

Who Pays, Who Benefits, and What the FAQ Claims

Policy backers argue the tax applies to fewer than 1% of households—roughly 20,000—by applying only to income above the $1 million threshold. The Washington State Budget and Policy Center’s FAQ describes mechanics intended to narrow the scope, including a standard $1 million deduction and exclusions such as tribal income, while also aligning definitions to reduce double taxation concerns. Even so, the details matter because complicated tax structures often expand over time through future legislative edits.

Supporters also point to programmatic benefits written into the broader budget approach described in coverage of the bill. Reported amendments and associated spending priorities include free school meals and expansions of tax credits such as the Working Families Tax Credit, plus targeted business tax relief like B&O credits for smaller firms. Conservatives will likely agree that families feel crushed by high costs, but the unresolved question is whether building new, permanent tax infrastructure is the right fix—or just another step toward bigger government.

Business Flight Concerns—and What the Available Reporting Can (and Can’t) Prove

Republicans argued on the House floor that the bill amounts to “a tax on Washingtonians” and that it is only a matter of time before lawmakers broaden it beyond millionaires. That warning lands because Washington competes directly with no-income-tax states like Florida for entrepreneurs and high earners who can move. The user’s premise references a “business icon” looking at Florida, but it does not identify a specific individual relocation tied to this bill, so the claim remains anecdotal based on the available sources.

What is clearly documented is the political and economic incentive structure. If the tax survives court scrutiny and produces the promised revenue, Democrats will likely cite it as proof they can fund expanding commitments without touching the middle class. If it triggers years of litigation, volatility, or visible out-migration among high earners, critics will cite that as proof the policy was a risky experiment. Either way, the next battlefield is the courts—where the 1933 precedent and Washington’s constitutional limits will be tested.
