How to Register a Foreign LLC in Washington

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 20, 2026 · Last updated Aug 20, 2026

An LLC formed outside Washington registers to do business there by filing a Foreign Registration Statement with the Washington Secretary of State. The filing fee is $180, and the application must include a certificate of existence dated within 60 days of submission. Expedited service costs an extra $100.

Do You Need to Register?

Washington requires a foreign limited liability company to register before it transacts business in the state. RCW 25.15, the Washington Limited Liability Company Act, is the controlling law. Like most state acts, it defines the requirement negatively: it lists activities that do not constitute transacting business, and everything else falls in.

The classic exclusions are maintaining bank accounts, holding member or manager meetings, selling through independent contractors, securing or collecting debts, owning property without more, and conducting an isolated transaction completed within a short period and not repeated. What does trigger registration is sustained presence: a Washington office, Washington employees, Washington inventory, or a repeated course of business with Washington customers.

Read the statute against your facts. Registering unnecessarily creates a permanent Washington registry footprint plus Department of Revenue tax accounts; failing to register when required exposes the company to the consequences the Act attaches to unregistered activity, which can include losing access to Washington courts until the registration is cured. The general framework is at how to form an LLC and what an LLC is.

Step 1: Confirm the Trigger

Start with a plain inventory of your Washington contacts: physical locations, employees, contractors, inventory, contracts performed in-state, and revenue sourced to Washington. If the only contact is remote sales shipped from elsewhere, registration is often not required - though Washington's tax nexus rules are separate and broader than the Secretary of State's registration rules, so a company can owe B&O tax without being required to register as a foreign LLC. Treat the two questions independently.

Step 2: Check the Name

Washington will not register a foreign LLC under a name that conflicts with a name already on the Secretary of State's records. Search before you file - see Washington business entity search. If your home-state name is unavailable in Washington, you register and operate under an alternate name in Washington. Trade names are handled through the Department of Revenue's business licensing system; see Washington DBA filing and what a DBA is. A state registry name gives no nationwide brand rights - for that, see trademark registration.

Step 3: Appoint a Washington Registered Agent

A foreign LLC registered in Washington must maintain a registered agent with a Washington street address. The agent signs a consent to serve as part of the registration and thereafter receives service of process and official notices. A post office box alone is not a valid registered office address. You may use a Washington resident, a Washington entity, or a commercial registered agent service, whose fee the state does not set. See Washington registered agent requirements and the national registered agent guide.

Step 4: Get a Certificate of Existence Dated Within 60 Days

This is the step that most often delays a Washington filing. Washington requires a certificate of existence (also called a certificate of good standing or certificate of status) from the LLC's home jurisdiction, and the Secretary of State's filing instructions state that the certificate must be dated within 60 days of the submission date to be acceptable for the Foreign Registration Statement filing record.

Two practical consequences follow. First, order the certificate close to the date you intend to file, not months ahead. Second, enter the LLC's name on the Washington filing exactly as it appears on the certificate of existence - the online instructions direct filers to match that document, and a mismatch is a common rejection reason. You upload the official document from the home jurisdiction as part of the online submission.

Step 5: File the Foreign Registration Statement

The registration document is the Foreign Registration Statement, filed with the Washington Secretary of State's Corporations and Charities Division. The filing fee is $180, plus the system's online processing fee. If you need faster handling, expedited service adds $100. All filing fees are non-refundable, so verify the certificate of existence and the name match before you submit rather than after.

The statement reports the LLC's true name, any alternate name for Washington use, the home jurisdiction and formation date, the principal office address, and the Washington registered agent and registered office with the agent's consent. You may select a future effective date up to 90 days from the filing date, which is useful when you want the registration to align with a lease start or a contract date.

Step 6: Apply for a Washington Business License

Secretary of State registration is a corporate-registry act; it does not open tax accounts or grant permission to operate. The next filing is the Business License Application with the Washington Department of Revenue, which is the single application Washington uses to open state tax accounts and to add city and state endorsements. The Department of Revenue states that the application fee varies and directs filers to its instructions to determine the correct processing fee for their combination of endorsements - do not assume a fixed amount.

Through that application a business typically registers for business and occupation (B&O) tax, retail sales tax collection if it makes taxable retail sales, use tax, and any city business license endorsements required where it operates. See Washington LLC tax filing requirements, business licenses, and the national business tax overview.

Washington's Tax Structure

Washington has no corporate income tax and no personal income tax on wages. It taxes gross receipts instead, through the business and occupation tax administered by the Department of Revenue. B&O tax is levied on the gross income of the business by classification - retailing, wholesaling, service and other activities, manufacturing, and others - each with its own rate. Because it is a gross receipts tax, it is owed on revenue rather than profit, so an unprofitable business can still owe B&O tax.

Confirm the current B&O rate for your classification and the current annual report fee directly with the agencies before budgeting; both are set administratively and change.

Ongoing Obligations After Registration

Once registered, a foreign LLC in Washington carries a recurring set of duties:

1. Annual report with the Secretary of State to keep the registration active - see Washington annual report.
2. Excise tax returns with the Department of Revenue on the frequency assigned to the account.
3. Registered agent maintenance - the agent and address must remain current.
4. Business license renewal, including city endorsements.
5. Home-state compliance, which continues unchanged in parallel.

Internal governance does not change on registration. The operating agreement adopted under the home state's law continues to control ownership, voting, and distributions; Washington does not file it. See Washington LLC operating agreement and S-corp vs LLC for the federal election. If you form in Washington instead of registering in, see Washington articles of organization, Washington certificate of formation, and Washington LLC cost.

Withdrawing from Washington

When Washington activity ends, withdraw the registration rather than letting it lapse. Filing the withdrawal stops the annual report obligation and closes the registry record cleanly; abandoning it leaves an entity that continues to accrue obligations and can be administratively terminated in a way that complicates later re-entry. Close Department of Revenue tax accounts at the same time so Washington stops expecting excise tax returns.

Withdrawal is not dissolution. The LLC continues to exist in its home state until it is dissolved there - see how to dissolve an LLC.

Terms are defined in the glossary; state cost comparison is at how much an LLC costs.
