Forming an LLC and getting a business license are two different processes. In most cases, once your LLC exists, Washington requires a Business License Application with the Department of Revenue — and your city may add its own requirements. The exact licenses depend on what your business does.
Two Separate Processes
Filing your Certificate of Formation creates a legal entity. It does not, by itself, license the business to operate. For an LLC, Washington instructs the business to first form the entity with the Secretary of State before completing the Business License Application. Many new owners are surprised to learn both steps exist — planning for both avoids surprises.
The Washington Business License Application
The Business License Application goes to the Washington State Department of Revenue. The current processing fee is $50 (additional variable charges may apply). The application covers your state business license and registers you for various state obligations at the same time.

Endorsements
Some business activities require additional endorsements on top of the basic license — for example, certain professional or regulated activities. Endorsements depend entirely on what your business actually does, so the Department of Revenue's application is the place to see which ones apply to you.
City Requirements
Many Washington cities require their own business license on top of the state one. Check your city's official website for its requirements, fees, and process — city rules vary from place to place.
Trade Names
If you want to operate under a name other than the LLC's legal name, a trade name registration may be needed. Whether it applies depends on how you present the business — the Department of Revenue explains trade names as part of the licensing process.
It Depends on Your Business Activity
Two businesses in the same city can have completely different licensing requirements because of what they do. Use the official sources above for your situation rather than assuming your requirements match another business's.
Common Mistakes
Assuming the LLC filing automatically licensed the business.
Skipping the city license because the state one is done.
Guessing about endorsements instead of checking the official application.
Operating before the license is issued, when the activity requires one.

FAQ
Does forming my LLC include my business license?
No. Formation creates the legal entity with the Secretary of State. Licensing is a separate process, typically handled with the Department of Revenue and your city.
Does every Washington business need the same license?
No — requirements depend on your business activity, location, and any endorsements that apply. That's why it's important to check the official sources for your specific situation.
What is a trade name?
A trade name lets a business operate under a name other than its legal name. Whether you need one depends on how you want to present the business — the Department of Revenue explains when it applies.
