A gavel with the word 'TAX' on it placed on a background of US dollar bills

Washington Democrats ram through a 9.9% ‘millionaire tax’ on incomes over $1 million, prompting business leaders to eye Florida’s no-income-tax haven as taxpayer flight looms.

Story Snapshot

WA Legislature passed SB 6346 after marathon debates, sending it to Gov. Bob Ferguson’s desk on March 11, 2026.
Tax targets under 1% of households (about 20,000), generating $3B+ annually from 2029 for education and health programs.
First state income tax attempt since 1933 Supreme Court struck down similar measure as unconstitutional.
Business icons signal relocation to Florida, highlighting risks of driving away job creators amid deficits.

Legislative Passage Amid Intense Debates

The Washington House passed the bill 51-46 after a grueling 25-hour debate spanning March 10-11, 2026. Four Democrats joined Republicans in opposition. The Senate followed on March 11 with hours of debate, advancing SB 6346 to Gov. Bob Ferguson’s desk as the session neared its March 12 end. Democrats hold slim majorities, overriding GOP warnings of economic harm. Rep. April Berg, the House sponsor, championed it as essential structural reform despite napping through parts of her own debate.

Tax Details and Promised Spending

The 9.9% tax applies to income exceeding $1 million, effective January 1, 2028, with first payments due April 2029. It affects fewer than 20,000 households, over 99% exempt. Projected $3 billion-plus annual revenue funds K-12 education, health care, and higher education to close multi-billion-dollar deficits from inflation and federal cuts. Amendments include free school meals, expanded Working Families Tax Credit, small business B&O credits, child care funding, and over-the-counter medicine exemptions.

Historical Precedent and Legal Risks

Washington has no broad income tax, relying on sales, property, and B&O taxes since a 1933 Supreme Court ruling invalidated a prior high-earner tax as a property tax. Democrats express optimism the court will reverse this precedent. Republicans like Rep. Joshua Penner decry it as disrupting a 90-year system, predicting inevitable expansion beyond millionaires. Businesses and high earners hold no veto power but eye litigation or ballot challenges. Ferguson shifted from veto threats to support after amendments sweetened the deal.

Gov. Ferguson backs the measure for addressing deficits while aiding working families and small businesses. Rep. Berg stated, “We’ve been on this path for decades… desperate need for structural tax reform.” Republicans counter, “A tax on Washingtonians, just matters when.” The Budget and Policy Center details mechanics: standard $1M deduction, tribal income exclusions, state capital gains rules to avoid double taxation.

Economic Warnings and Business Exodus

High earners in tech and finance sectors face the brunt, risking relocation to no-income-tax states like Florida. A prominent business icon’s consideration of Florida underscores conservative fears: punitive taxes chase away innovators and jobs, echoing national frustrations with leftist fiscal mismanagement under Biden’s era now ended by President Trump’s return. Short-term revenue aids low-income programs, but long-term taxpayer flight threatens stability. This aligns with common-sense limited government principles, prioritizing growth over redistribution.

Amendments aim to blunt small business pain with B&O credits and hygiene exemptions, yet opponents argue it sets a slippery slope. Amid Trump’s 2026 push for fiscal restraint federally, states like Washington doubling down on tax hikes highlight blue-state overreach, potentially accelerating population and capital shifts to red strongholds.
