Business Registration

Every business operating within the City of Woodinville must be registered. This includes both businesses located within City limits and those coming into Woodinville to conduct business. This is not a business license. It is a registration with the City that you are doing business here. Please be aware that there is a fine for failure to register.

Registration allows the Police to make contact in an emergency. Maintaining a current list of business activities allows the City to better allocate resources and support economic development.

State License Requirements

All businesses operating in the State of Washington must obtain a Washington State Master Business License. The Master Business License registers the business for State tax purposes and registers the trade name. You need to file a Master Business Application when you first start your business, or when you change or update your business. The Master Business Application can be found on the Washington State Department of Revenue website, Business.wa.gov/BLS.

In addition to a Washington State Master Business License, your business may require additional State of Washington licenses that are not covered under your State Master Business License. View a complete list of professional licenses.

King County Requirements

A King County business license is required only if:

If the business is located in unincorporated King County, the business must be in compliance with zoning code regulations. See business zoning for more information on conducting a business out of your home or other zoning questions.

If the business is located or operates within city limits of any incorporated city in King County (such as Seattle, Kent, Issaquah, etc.), you must check with the city instead of King County to find out the city's requirements for business licenses. For more information, see city licenses .
