City of Seattle B&O Tax

Entities engaging in business inside the Seattle city limits are required to pay a business and occupation (B&O) tax. The B&O tax is calculated based on gross business receipts (less allowable deductions). Tax rates and classifications are broken out by your business activity. If your business has more than one activity, multiple classifications must be used. Note, the Seattle B&O tax is in addition to the Washington State B&O tax.

Special tax situations may apply. It’s best to review this information prior to completing the tax filing to see if your business is responsible for any additional taxes.

Depending on your business, you may be responsible to pay the Seattle B&O taxes quarterly or annually. Log in to FileLocal account to retrieve the due dates for your business.
