Washington is a technology and aerospace powerhouse - home to Amazon, Microsoft, Boeing, Starbucks, and Costco - clustered around the Seattle-Bellevue metro. The state also leads in aerospace manufacturing, global trade through its deepwater ports, and agriculture (apples, wine, and wheat), with a fast-growing clean-energy sector. Its lack of a personal income tax and heavy concentration of high-wage tech jobs shape both its economy and its unusual tax structure.
Washington has no personal income tax, but that does not mean no business tax. The state's signature Business & Occupation (B&O) tax is levied on gross receipts - total revenue, with no deduction for costs or losses - at rates that vary by activity (for example, roughly 0.471% for retailing, 0.484% for manufacturing and wholesaling, and about 1.5% or more for services, as of 2026 - confirm current rate). Sales tax is also high: 6.5% state plus local rates that push combined totals to roughly 9% to 10.35%, with Seattle near the top. Washington additionally imposes a 7% excise tax on long-term capital gains above a threshold (around $270,000, with a higher rate on very large gains, as of 2026 - confirm current rate and threshold), and there is no corporate income tax.

Tides is based in Greenville, SC and serves clients across the country. We know Washington's business climate cold — no state income tax at all, but the Business & Occupation (B&O) tax on gross receipts and combined sales taxes that top 10% in Seattle — and the industries that drive Puget Sound, Spokane, and Eastern Washington.
No hourly billing surprises. You pay one flat rate each month based on your transaction volume — and you always know exactly what you're getting.
We don't just hand you a spreadsheet. We deliver clean, readable financial reports each month with plain-language summaries so you can make decisions — not just file paperwork.
