Washington Taxes on Businesses
Sales & Use Tax
While Oregon, Montana, and Alaska generally do not levy sales or use taxes, the State of Washington has one of the highest sales and use tax rates in the nation. This has made the State of Washington a beehive of sales and use tax controversies, many of which are difficult to understand and analyze. In addition to the sales tax imposed by the state, counties and cities may also impose another layer of sales tax.
Business and Occupation (B&O) Tax
Washington is one of few states that impose a Business and Occupation (B&O) tax on gross revenue (rather than net income). Strictly speaking, this is not an income tax, but rather a tax imposed on all Washington businesses for the privilege of doing business in Washington. In practical terms, this means that no deduction may be used to reduce the tax base (your gross revenue) on which a B&O tax is assessed.
