Ask the Taxman- How do you file Washington state business taxes?
Source: Quora
Answer:
Washington, unlike many other states, does not have an income tax. Washington’s B&O tax is calculated on the gross income from activities. This means there are no deductions from the B&O tax for labor, materials, taxes, or other costs of doing business. It is measured on the value of products, gross proceeds of sale, or gross income of the business.
The Washington B&O tax is reported and paid on the excise tax return or by electronic filing.
If you are a new business, register with the Department of Revenue
first. Once you are registered, you will receive information about filing.
