🌲 COUNTRY A Washington VS 🌴 COUNTRY B California

Washington State and California form the technology corridor on the US West Coast — Seattle (Microsoft, Amazon, Boeing) versus San Francisco and Silicon Valley. For business owners and tech workers, the tax comparison is meaningful but more nuanced than it first appears. Washington has no personal income tax and no corporate income tax. This is the headline advantage over California's 13.3% top rate and 8.84% corporate tax. Washington does impose the Business & Occupation (B&O) tax — a gross receipts tax applied to most Washington businesses. B&O rates vary by business activity: 1.5% for most services, 0.484% for manufacturing and extracting, 0.484% for wholesaling, 0.471% for retailing. Unlike an income tax, B&O is calculated on gross revenue regardless of profit — which can be burdensome for high-revenue, low-margin businesses. For a consultant with $200,000 in revenue and $150,000 in profit: B&O tax ≈ $3,000 (1.5%); California income tax on $150K profit ≈ $9,561 plus the $800 minimum franchise tax (no LLC fee below $250,000 of revenue). Washington wins by about $7,400/year. For a retailer with $500,000 gross revenue and $50,000 profit: B&O ≈ $2,355 (0.471%); California income tax on $50K ≈ $973 plus the $800 minimum franchise tax and a $2,500 LLC fee at that revenue level — about $1,900 more than Washington's B&O. Washington also introduced a 7% capital gains tax in 2022 on gains above $278,000 (2025 amount, adjusted annually) — affecting high earners with investment income, but not business operating income. For most service businesses and tech workers, Washington's B&O cost is far below California's income tax burden.
