‘A pattern in this state of intimidation’: Let’s Go Washington founder urges Microsoft to join income tax fight

Let’s Go Washington founder Brian Heywood is urging major employers like Microsoft to publicly oppose Washington’s new income tax, signed into law by Governor Bob Ferguson in March 2026. Initiative 645 would repeal the tax, which applies to income beginning in 2028 with first payments due in 2029. Heywood argues that corporate silence leaves businesses vulnerable to future taxes and threatens a statewide payroll tax if voters retain the income tax.
