Invoicing in Washington — What Businesses Typically Include

Sales Tax in Washington
Washington has a state sales tax rate of 6.5%. Local additions in Seattle, Bellevue, and the greater Puget Sound area bring combined rates to 9.23–10.55% — among the highest in the US. Washington sales tax applies to tangible goods and some services. Most professional services are not subject to Washington sales tax, but Washington's Business and Occupation (B&O) tax applies to gross receipts from most business activities — including services — at rates ranging from 0.471% to 1.8%. This is separate from sales tax.
Business Structures in Washington
Sole proprietors operating under a business name must register an Assumed Name with the Washington Secretary of State. LLCs are formed with the Washington Secretary of State and pay an annual report fee. Washington's tech economy — centred on Seattle and the Eastside — is one of the most significant in the world.
No State Income Tax
Washington has no state income tax on wages or regular business income. However, Washington levies a 7% capital gains excise tax on long-term capital gains above $250,000 per year. Washington also has the Business and Occupation (B&O) tax on gross business receipts. Self-employed Washington residents still owe federal self-employment tax and income tax to the IRS.
The Washington Business Economy
Seattle and the greater Puget Sound area host one of the world's largest concentrations of tech professionals, with Amazon, Microsoft, and hundreds of other tech companies creating enormous demand for freelance developers, designers, and technical consultants. Washington's no-income-tax status (on wages) makes it one of the most tax-advantaged locations for high-earning tech freelancers.
