Washington saves approximately $10,000–$18,000+/year vs California at $150K–$200K business profit for service businesses (after B&O tax of ~1.5% on gross revenue). For high-revenue, low-margin businesses, B&O tax can offset some or all of the income tax saving. Washington's 7% capital gains tax applies to investment gains above $262K — not to normal business operating income.

FAQ

Frequently Asked Questions

How does Washington's B&O tax work?

Washington's Business & Occupation (B&O) tax is a gross receipts tax — it applies to total business revenue, not profit. The rate depends on business classification: 1.5% for service and professional businesses (consulting, law, accounting, technology services), 0.471% for retail sales, 0.471% for wholesaling, 0.484% for manufacturing. B&O is calculated on all Washington gross revenue above the annual small business threshold ($125,000 for quarterly filers; some businesses get a credit that effectively exempts the first $32,000). Unlike income tax, B&O applies even if the business operates at a loss — making it harder for early-stage businesses with high revenue and low margins. Most profitable service businesses find their B&O cost is substantially less than California's income tax would be.

Does Washington's capital gains tax affect business owners?

Washington's 7% capital gains tax (enacted 2022, upheld by state Supreme Court 2023) applies to long-term capital gains above $262,000 per year from sales of stocks, bonds, and other capital assets. It does NOT apply to real estate (excluded), qualified small business stock (B corporation and startup equity may qualify for exclusion), retirement accounts, or agricultural property. For a business owner who sells their business as an asset sale (selling business assets rather than entity shares), the proceeds may or may not trigger the capital gains tax depending on how the sale is structured. A CPA is essential for business exit planning in Washington.

Is Seattle better than San Francisco for tech business owners on taxes?

On state income tax: yes, significantly. A software engineer or tech consultant earning $250,000 in Washington pays zero state income tax; in California they pay approximately $22,500/year. A tech startup founder drawing $300,000 in salary saves approximately $28,000/year in state income taxes in Washington vs California. Seattle's B&O tax on service businesses at 1.5% of revenue typically amounts to $2,000–$5,000/year for consultants in this income range — still far below California's income tax. The comparison is most favourable for high-earning service professionals and tech workers.

How does Washington compare to California for Amazon, Microsoft, or Boeing employees?

For employees of major Washington employers: Washington state income tax = $0; California state income tax on a $200,000 tech salary = approximately $16,000–$19,000/year. This is one reason Washington state has seen net inflows of tech talent from California since 2019. Additionally, Washington's equity compensation (RSUs, stock options) is generally not subject to Washington income tax — though capital gains from selling the resulting shares above $262,000 may be. California taxes all RSU income and capital gains at the full progressive rate. For an Amazon or Microsoft employee exercising significant equity, the Washington vs California difference can easily reach $30,000–$80,000+ per year.
