How to Register a Foreign LLC in Washington
The process of registering an out-of-state LLC in another state is called foreign qualification. To register an LLC in Washington, you’ll need to do three things:
- Appoint a Washington registered agent.
- Obtain a certificate of good standing from your home state.
- File registration paperwork with the Washington Secretary of State, Corporations Division (SOS).
Here’s our guide to getting it right and keeping your business in good standing with the state of Washington.

1. Check Your LLC’s Name Availability
You already have a business name, but another business in Washington could be using it. Since your business name needs to be unique in Washington, your first step is to perform a free business name search. If your LLC’s name is available, you can either reserve your business name for $30 before you file, or you can simply proceed with registering your business as a foreign LLC in Washington.
Name taken? You’ll need to register a Washington DBA (doing business as) name for your foreign LLC with the Washington Department of Revenue. To do so, you’ll need to complete a Business License Application (online or by mail) and pay the $24 filing fee to secure your LLC’s name.

2. Appoint a Washington Registered Agent
Washington state regulations dictate that your LLC will need a Washington registered agent. Your registered agent needs to be available during normal business hours to receive legal correspondence and official paperwork on behalf of your LLC. Your registered agent is required to have a physical address in Washington.
You can appoint someone you know, a family member, or an employee to act in this capacity, or you can do what most foreign LLC owners do, which is hire a professional registered agent service.
Not unless you live in Washington. That’s why most foreign LLC filers hire a registered agent service.
A professional registered agent service not only ensures that your important mail won’t go unanswered, but they also protect your privacy, since you can list your agent’s business address on your Washington registration documents instead of your own.

4. Get a Certificate of Existence
Washington requires you to include a certificate of existence, also called a certificate of good standing, with your foreign registration filing. The certificate basically proves that your LLC has fulfilled its legal obligations in its home state or jurisdiction. The documentation must be dated within 60 days of your foreign LLC registration.
You can to request your certificate online through the government agency with which you originally filed formation documents in your home state (usually the Secretary of State’s office). Most states charge a small fee and will make your certificate of existence available almost immediately.

5. Complete the Foreign Registration Statement
The next step is to file a Washington Foreign Registration Statement with the Washington Secretary of State. This document is your application to do business in the Evergreen State. You can file online or fill out a paper form and mail it in. To fill out your paperwork, you’ll need to provide:
- UBI number (if your LLC has registered with the Secretary of State previously—otherwise, you’ll be assigned one later)
