When Is Washington Foreign LLC Registration Required?

You must register as a foreign LLC in Washington if your LLC is formed in another state and transacts business in Washington State. Washington law defines this broadly:

  • Maintaining an office or place of business in Washington
  • Having employees working in Washington
  • Regularly soliciting orders or sales in Washington
  • Owning, leasing, or operating real property in Washington
  • Deriving substantial revenue from Washington-based customers

Activities That Generally Do NOT Require Registration

  • Making isolated or occasional sales in Washington
  • Holding internal meetings or board meetings
  • Maintaining bank accounts in Washington
  • Defending lawsuits in Washington courts

Penalty for non-registration: Operating in Washington without proper foreign LLC registration can result in civil penalties and your LLC being barred from using Washington courts to enforce contracts.

How to Register a Foreign LLC in Washington State

  1. Obtain a Certificate of Existence/Good Standing from your home state
    Request a certificate of existence or good standing from your home state's Secretary of State (or equivalent). Washington requires the certificate to be dated no more than 60 days before you submit the Foreign Registration Statement, or the filing is returned for correction.
  2. Choose a Washington registered agent
    Designate a registered agent with a physical Washington street address, as required by RCW 23.95.415. This can be an individual Washington resident or a commercial registered agent service registered with the Secretary of State. See our Washington registered agent requirements for details.
  3. File the Foreign Registration Statement
    File online through the Washington Secretary of State's Corporations & Charities Filing System (CCFS) at sos.wa.gov, or by mail to the Secretary of State in Olympia. Pay the $180 filing fee. The Foreign Registration Statement (under RCW 23.95) is Washington's equivalent of a certificate of authority.
  4. Verify name availability in Washington
    Search the Washington Secretary of State's business name database to confirm your LLC's name is available. If it's taken, you'll need to register an assumed name for Washington operations.
  5. Register with the Washington Department of Revenue
    If your LLC will owe Washington B&O tax or collect sales tax, register with the Department of Revenue at dor.wa.gov to obtain your business license and tax accounts.

Frequently Asked Questions

Do I need to register as a foreign LLC in Washington State?

You need to register if your LLC is formed in another state but transacts business in Washington — such as having employees, an office, or regularly soliciting customers in Washington. Purely online businesses with no physical presence in Washington may not need to register, but this depends on specific facts.

Can my foreign LLC use its existing name in Washington?

Your LLC must register under its existing legal name in Washington if available. If that name is already taken by another Washington business, you may need to use an assumed name (trade name) for Washington operations only.

Does a foreign LLC in Washington owe B&O tax?

Yes. Foreign LLCs that transact business in Washington are subject to Washington's Business & Occupation (B&O) tax on gross receipts derived from Washington-sourced activities — the same as domestic Washington LLCs.

What are the ongoing requirements for a foreign LLC in Washington?

Foreign LLCs in Washington must file an annual report ($70/year, due by the last day of the registration anniversary month), maintain a Washington registered agent, and comply with Washington's B&O tax and sales tax requirements. A late annual report incurs a $25 delinquency fee.

What happens if I operate in Washington without registering as a foreign LLC?

Transacting business in Washington without proper registration exposes your LLC to penalties and bars it from using Washington courts to enforce contracts until it becomes properly registered.
