Business & Occupation Tax

The State of Washington, unlike many other states, does not have an income tax.  As an incorporated city, one way the City of Bainbridge Island raises revenue is through its Business & Occupation (B&O) Tax levied on businesses engaging in business in the City. Businesses with gross revenue in the City of more than $150,000 are subject to the City’s Business and Occupation Tax set at 1/10 of 1% (0.001). The City’s B&O Tax is a gross receipts tax; that is, the tax is measured on the value of products, gross proceeds of sales, or gross income of the business in the City. Being a gross receipts tax means there are no deductions for labor, materials, or other costs of doing business. The tax is filed annually reporting gross revenue for the prior calendar year. This B&O Tax is separate from and in addition to the Washington State B&O Tax. 

Definition of "Gross Revenue on the Island":  Under Bainbridge Island Municipal Code (BIMC) 5.05.050, the B&O Tax is levied on every person engaging in business activities within the City.  The definition of "engaging in business" can be found at BIMC 5.05.030.  For B&O Tax purposes, BIMC 5.05.050.A.4 defines "total gross revenue on the island" as the "gross proceeds of sales of the business without regard to the place of delivery of articles, commodities or merchandise sold."
  • The Municipal Code does not distinguish between retail and wholesale revenue. Both types of revenue are considered part of gross revenue.
  • The Municipal Code does not distinguish between sales made to Native American tribes and the general public.

Note:  The City’s B&O Tax is a gross receipts tax meaning there are no deductions for labor, materials, or other costs of doing business.
