How to Register a Foreign LLC in Washington (Step-by-Step)

Step 1: Determine If You Need Washington Foreign Qualification

Before you begin the business registration process, it’s important to assess whether your business needs to be registered as a foreign limited liability company in Washington. In general, if your business has a physical presence or is transacting business within Washington, you must file for foreign qualification. This includes having employees, maintaining an office, or generating income in the state.

Step 2: Obtain a Certificate of Existence from Your Home State

To register as a foreign LLC in Washington, you must provide a certificate of existence or a certificate of good standing from your home jurisdiction. This document proves that your LLC is properly registered and in good standing with its home state.

The certificate must be dated within 60 days of your filing date, and it must be submitted with your application to the Washington Secretary of State¹.

Step 3: Reserve a Business Name (If Necessary)

If your business name is already in use in Washington, you will need to choose an alternate name for your LLC. The name must be distinguishable from other businesses registered in the state. You can check name availability through the Washington Secretary of State’s online database². If necessary, you can reserve the name for $30 (file online for faster processing).

Step 4: Appoint a Registered Agent in Washington

Every foreign LLC in Washington is required to appoint a registered agent who has a physical address within the state. The registered agent serves as the official point of contact for receiving legal documents, government notices, and other correspondence.

Step 5: File the Foreign Entity Registration with the Washington Secretary of State

Once you have gathered all the necessary documents, you can file your Washington Foreign LLC registration with the Washington Secretary of State. The official form is called a Foreign Registration Statement, which can be filed online³ or by submitting paper forms. File online for $180, with an additional $50 fee for expedited service.

Your application will include the following information:

• The name of your LLC and any alternate name being used in Washington.
• The home state and date of formation.
• The address of your principal office.
• Your appointed registered agent’s contact information.
• The Certificate of Existence from your home state.

Once the documents are submitted and approved, your LLC will be officially registered as a foreign entity in Washington.

Step 6: File the Initial Report

After Foreign LLC registration, you must file an initial report within 120 days of business registration. This report includes the names and addresses of your LLC’s members or managers, as well as the address of your principal office.

The filing fee for this report is typically $60, and it must be filed with the Secretary of State⁴. The initial report helps to maintain your LLC’s good standing with the state.

Step 7: Apply for Business Licenses and Permits

You may need to apply for various state or local licenses and permits. In Washington, businesses must obtain a state business license through the Washington State Business Licensing Service. Depending on your industry and location, additional licenses or permits may be required.

Step 8: Comply with Ongoing Filing and Tax Obligations

Each year, your LLC must file an annual report. You can submit it through your existing online account, where you'll also receive reminders and manage any required updates. Washington has a Business and Occupation (B&O) tax⁵, as well as sales and use tax for certain businesses.

Your annual report is due by the end of your LLC’s anniversary month each year, and failure to file this report may result in late fees or even administrative dissolution. You will also need to maintain accurate state tax filings and business records to remain in good standing.

How to Maintain a Washington LLC as a Nonresident

You don’t need to live in Washington to keep your foreign LLC compliant, but you do need to stay on top of the state’s requirements. As a nonresident, here’s what maintaining your LLC involves:

• Keep your registered agent active. Your registered agent must always have a physical address in Washington and be available during business hours. If you move, change agents, or stop using a service, update the Secretary of State right away.
• File your annual report on time. This report is due each year in the same month your LLC was registered. It can be submitted online using your account with the Washington Secretary of State.
• Maintain good standing in your home jurisdiction. Washington will revoke your authority to operate if your LLC becomes inactive or dissolved in its home state.
• Renew your business license and local permits. Most foreign LLCs must renew their Washington business license each year and meet any local licensing requirements tied to their activities or industry.
• Update the state when things change. If you change your LLC’s name, management, address, or structure, notify the state by filing the appropriate updates. Most updates can be handled through your online account.
