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.

A King County business license is required only if:

1. The business engages in a regulated activity and
2. The business is located in and/or operates in unincorporated King County .

See types of licenses for more information.

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, Woodinville, etc.), you must check with the city instead of King County to find out the city's requirements for businesses. For more information, see city licenses.
