A Certificate of Formation in Washington State is the legal document you file with the Secretary of State to create a limited liability company. The filing fee is $180, and once the state accepts the certificate, your LLC officially exists as a separate legal entity. You can file online through the Corporations and Charities Filing System or send a paper application by mail.
Why Filing This Document Matters
Your LLC comes into existence the moment the Secretary of State files the certificate. Not when you sign it. Not when you start taking customers.1Washington State Legislature. Washington Code Chapter 25.15 – Limited Liability Companies Until that filing is accepted, anything you do commercially runs through you personally as a sole proprietorship or, if you have partners, as a general partnership. There is no legal wall between your business debts and your personal bank account.
After the filing, the LLC becomes its own legal person. It can sign contracts, hold property, sue, and be sued in its own name. The practical payoff for you is the liability shield: your home, your car, and your personal savings are generally protected if the business is sued or cannot pay its debts. What you can lose is usually capped at what you put into the company.
Information You Need Before You File
RCW 25.15.071 sets out what the certificate must include. Gather this before you open the application:
- A business name that includes “Limited Liability Company,” “LLC,” or “L.L.C.” The name cannot use “corporation,” “incorporated,” or their abbreviations, and it must be distinguishable from every other entity already on file.2Washington State Legislature. Washington Code 23.95.305 – Name Requirements for Certain Types of Entities
- A registered agent with a Washington street address who has consented to the role. This is the person or company authorized to receive lawsuits and official notices for your LLC.3Washington State Legislature. Washington Code 23.95.415 – Designation of Registered Agent
- A principal office street address. A PO box or private mailbox will not work for the principal office, though you can list one as an alternate mailing address. The principal office can be located outside Washington.4Washington Secretary of State. Contact Info Requirements and Updates
- A dissolution date, only if you want the LLC to end automatically on a set date. Most filers leave this blank so the LLC continues indefinitely.
- The executor’s name, address, and signature. This is usually a founder, but it can be an attorney or another authorized representative.
You can add optional provisions under the statute’s catch-all for “any other matters the members decide to include.” A broad purpose statement such as “to engage in any lawful activity” is common because it spares you from amending the certificate later if the business branches into something new.
How to File and What It Costs
Two ways to file:
- Online through the Corporations and Charities Filing System on the Secretary of State’s website. Online filings are typically processed within a few business days.5Washington Secretary of State. Corporations and Charities Filing System
- By mail to the Corporations and Charities Division in Olympia. Paper filings generally take one to three weeks.
The base fee is $180. If you need the filing processed faster, expedited service costs an additional $100 and is generally finished within three business days.6Washington Secretary of State. Limited Liability Company (LLC) and Professional LLC (PLLC) Filing Resource Page
What to Do Right After the State Approves Your Filing
The certificate creates the entity. It does not, on its own, put you in business. A few steps come next.
State Business License and UBI Number
Most Washington businesses have to apply for a state business license through the Department of Revenue. When the license is issued, you receive a nine-digit Unified Business Identifier, or UBI. That number follows your LLC across state agencies and goes on your tax filings and future updates. File the Certificate of Formation first, then apply for the business license.7Washington Department of Revenue. Apply for a Business License
Federal EIN
Most LLCs also need a federal Employer Identification Number from the IRS. You’ll need one if you plan to hire employees, open a business bank account, or if the LLC has more than one member. The IRS recommends forming the entity with the state before applying for an EIN to avoid processing delays.8Internal Revenue Service.

Operating Agreement
Washington does not require you to file an operating agreement with the state, and it is not part of the certificate. But having one is strongly advisable. Under RCW 25.15.018, the operating agreement governs the relationships among members and the rights and duties of any managers.9Washington State Legislature. Washington Code 25.15.018 – Effect of Limited Liability Company Agreement, Nonwaivable Provisions Without one, your LLC defaults to the rules in Chapter 25.15 RCW, which may not match how you actually intend to run things. The agreement typically covers ownership percentages, how profits and losses are split, voting rights, whether the LLC is member-managed or manager-managed,10Washington State Legislature. Washington Code 25.15.151 – Member-Managed Limited Liability Companies and what happens when a member leaves or sells their interest. Even a single-member LLC benefits from one, because it reinforces the separation between you and the business if your liability shield is ever challenged.
Professional and Industry Licenses
Forming an LLC does not authorize you to practice a regulated profession or run a licensed trade. Construction, food service, real estate, healthcare, and similar fields need separate occupational or professional licenses from the appropriate state or local agency. Those are independent of the certificate.
Keeping the LLC in Good Standing
Filing the certificate is not a one-time event. Every Washington LLC must file an annual report with the Secretary of State to stay in good standing. The report is due each year by the end of the month in which your LLC was originally formed, and the fee is $60. The report confirms basic information like your registered agent and principal office address. It is not a financial disclosure.
If you miss the annual report, lose your registered agent, or fall out of compliance in other ways, the Secretary of State can begin proceedings to administratively dissolve your LLC.1Washington State Legislature. Washington Code Chapter 25.15 – Limited Liability Companies A dissolved LLC can only wind up its existing affairs. It may lose the right to bring lawsuits, and people acting on its behalf during the dissolution period can be personally liable for debts the company takes on. You can apply for reinstatement by fixing the issue that caused the dissolution, paying what you owe, and filing a reinstatement application. Reinstatement generally relates back to the date of dissolution, but if another business claimed your name while you were dissolved, you may not get it back.
Operating Outside Washington
Your Washington certificate authorizes the LLC to do business in Washington. If you expand into other states, you will generally need to file for foreign qualification in each one by submitting a Certificate of Authority, and most states will ask for a Certificate of Good Standing from Washington as part of that application.11U.S. Small Business Administration.
