Washington's Millionaire Tax Passed — $3B+ Annually for Child Care, School Meals, and Working Family Tax Credits
Washington's Millionaire Tax Passed — $3B+ Annually for Child Care, School Meals, and Working Family Tax Credits
What actually happened
On March 30, 2026, Washington Governor Bob Ferguson signed Engrossed Substitute Senate Bill 6346 into law — the state's first personal income tax since the Great Depression. The legislation imposes a 9.9 percent tax on individual and household income exceeding $1 million annually.
The final passage followed a 24-hour House debate and a 51-46 vote on March 12, after the Senate had passed it 27-22 in February. The bill applies to approximately 20,000 to 30,000 households — less than 1 percent of Washington residents.
Revenue is projected at 3.5 to 3.7 billion annually once collections begin in 2028, with first filings due in April 2029.
The law includes tax relief provisions:
Free school breakfast and lunch for all Washington public school students
5 percent of annual proceeds to the Fair Start for Kids Act, funding child care and early learning providers
Expanded Working Families Tax Credit to 460,000 additional households, including young adults and seniors
Sales tax elimination on diapers, personal care products, and over-the-counter medications
Business & occupation tax exemption for approximately 70 percent of Washington businesses
The system at work is the regressive state tax structure's dismantling.
Washington has been one of nine states with no personal income tax, relying instead on sales, property, and business taxes . That structure is among the most regressive in the country. Households in Washington's bottom 20 percent pay 13.8 percent of their total income in state and local taxes. Households in the top 1 percent pay 4.1 percent — less than one-third the rate .
The mechanism is progressive tax legislation as infrastructure repair. The law does not create a broad income tax. It creates a high-earner surtax with a $1 million standard deduction, exempting the first million entirely . That structure survived legislative negotiation because it targets a small population while funding universal programs — school meals, child care, working family tax credits — that benefit 100 percent of residents .
The political coalition behind this bill is worth naming. Senate Majority Leader Jamie Pedersen sponsored it. Governor Ferguson conditioned his signature on expanded relief provisions . Over 80,000 people signed in for public testimony . Republicans opposed unanimously, arguing it is unconstitutional and unnecessary . The League of Women Voters supported it on grounds of tax fairness and program necessity .
The law is scheduled for implementation January 1, 2028 . That delay is not administrative. It is defensive. Lawmakers explicitly built in time for two things they name as certain: legal challenge and voter referendum .
The real-world harm is not in the passage. It is in the pre-existing condition this law is designed to treat.
The harm pre-dates the law. Washington's regressive tax structure has meant the people with the least pay the most as a share of their income. When budget deficits hit — from lower revenue projections, increased operating costs, and decreased federal funding for health care and food programs — services for low-income families, public schools, and health care are first to shrink . That is the design of a regressive system: the poor subsidize the state's operations, and when the state runs short, the poor lose services first.
The harm this law attempts to address is the chronic underfunding of child care, the stigma of unpaid school meals, the miles low-income families drive to buy diapers without sales tax because their own county hasn't exempted them. Those are not natural disasters. They are policy outputs.
For survivors of domestic violence — who are disproportionately low-income and disproportionately raising children alone — child care access determines whether they can work. School meals determine whether their children eat. Tax credits determine whether rent is possible . Those are not abstract benefits. They are survival infrastructure. Washington's pre-existing tax structure made that infrastructure unreliable. This law attempts to stabilize it.
What happens next
Legal challenges are already anticipated. Opponents argue the millionaire tax violates the state constitution's uniformity clause and prohibition on income taxes . The state supreme court previously upheld Washington's capital gains tax against similar challenges in 2023, which supporters cite as precedent . Voters could also block the law via referendum or initiative, which organizers have signaled they intend to pursue .
If the law survives, collection begins in 2028, and the first revenue flows to childcare, meals, and tax credits in 2029.
A state that taxed the poor more than the rich for 93 years has passed a law taxing millionaires to feed children — and the legal and political machinery to overturn it is already running.
She doesn't chase trends. She channels truth.
