File with the Washington Secretary of State

Before you file in Washington

Every Washington business is identified by its Unified Business Identifier (UBI). If you defer the initial report at formation, it is due within 120 days for a $10 fee.

The steps

  1. Check that the name is free

    Start from our Washington business lookup or go straight to the official Washington search. Search the name in the Corporations and Charities Filing System (CCFS). Final availability is decided by Secretary of State staff when they process the formation, and the search does not show pending submissions.

    The name must also say that it is an LLC, with words such as "Limited Liability Company" or "LLC". Our name availability guide covers what makes two names too close.

  2. Reserve the name, if you want to hold it

    Optional. If you are not ready to file, a reservation costs $30 and holds the name for 180 days, not renewable. Source, checked 2026-10-26

  3. Appoint a registered agent

    The agent receives lawsuits and state mail for the LLC at a street address in Washington. You may serve yourself if you have one there; a commercial agent keeps your own address off the record. See what a registered agent does.

  4. File the Certificate of Formation

    File the Certificate of Formation (with Initial Report) with the Washington Secretary of State. The state fee is $180. Includes the initial report. Source, checked 2026-10-26

  5. Get an EIN from the IRS, free

    Once Washington approves the LLC, apply for an Employer Identification Number on the IRS EIN page. It is free and issued online as soon as the application is approved; a site that charges for it is selling a service, not the number.

  6. Write an operating agreement

    It can be short: who owns what, how profit is shared, who decides and how a member leaves, signed by every member, or by you alone for a one-person LLC. It stays with the company's records rather than being filed (what to put in it).

  7. Keep it in good standing

    Annual Report: $70, every year, due by the last day of the month you formed; it can be filed up to 180 days early. Source, checked 2026-10-26

    Business and Occupation (B&O) tax: Washington has no income tax on LLCs, but it levies the B&O tax on the gross receipts of businesses with substantial nexus in the state, rather than on net income. Source, checked 2026-10-26

    File an update whenever the registered agent or the LLC's address changes, so the state's notices reach you.
