How to Start an LLC in Washington

Your LLC needs a name that meets Washington's naming rules and is distinct from existing registered businesses. Coming up with a few strong options before you search makes the process much smoother.

Before filing, search the official Washington business records to see whether your name is already in use. Finding a conflict early saves you a rejected filing and re-filing.

Every Washington LLC needs a registered agent — the person or service that receives official legal and government mail. You can often act as your own, or hire an optional service.

You form the LLC by filing a Certificate of Formation with the Washington Secretary of State, Corporations & Charities Division. The current base state filing fee is $180. Additional online processing charges may apply.

An operating agreement documents how your LLC is owned and run. It's especially important for multi-member LLCs, and worth having even for single-member ones.

An Employer Identification Number is a federal tax ID issued by the IRS. The application is free and, when filed online, the number is typically issued immediately.

Forming the LLC and getting licensed are separate steps. Washington generally requires a Business License Application with the Department of Revenue once the entity exists.

Depending on what your business does and where it operates, additional endorsements, permits, or city licenses may apply. Verify your specific activities with the state and your city.

A separate business bank account and basic bookkeeping keep your LLC's money distinct from your own — which matters for both taxes and the liability protection the LLC is designed to provide.

Washington LLCs file an annual report with the Secretary of State. The report is due by the entity's expiration date, which the Secretary of State describes as the last calendar day of the month in which the business was first formed or registered. Keeping up with this filing helps your LLC stay in good standing.
