All individuals and firms doing business in Bellingham, whether located inside or outside the City limits, must register with the City Finance Department and are subject to the business and occupation (B&O) tax, unless specifically exempted by Bellingham Municipal Code.
B&O taxes are based on the gross revenues of a business. This is similar to the taxation method used by the State of Washington. B&O taxes support a wide variety of City services, including: police, fire, park, and library services. For more information about the B&O tax, please refer to A Guide To Business and Occupation Tax (PDF).
The State Department of Revenue also administers a State B&O Tax. This is not jointly administered for the State and City.
