Entity Name and Address

Having a creative and smart business name is important but not as important as having a legally correct name.

When you choose a name for your business, you have to make sure the name:

  • meets Washington naming guidelines. 
  • is not already in use by another business in Washington. 

Follow the Washington Naming Guidelines:

  • Your name must contain the words "limited liability company," the words "limited liability" and abbreviation "Co.," or the abbreviation "L.L.C." or "LLC.”
  • Your name cannot include any of the following words or abbreviations: cooperative, partnership, corporation, incorporated, Corp., Ltd., Inc., LP, L.P., LLP, L.L.P., LLLP, L.L.L.P, or any words or phrases prohibited by any statute of this state.
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • In some states, certain restricted words (e.g., Bank, Attorney, University) may require additional paperwork and a licensed individual to be part of your LLC.
  • Your name must be distinguishable from any existing business in the state. This includes Washington reserved names.

Check Name Availability:

Is your name available in Washington? Make sure the name you want isn't already taken by doing a name search on the Washington Department of Revenue website.

Effective Date and LLC Duration

State whether you would like the Certificate of Formation to be effective or if there is a future effective date. Also, note whether the LLC’s existence will be perpetual or if there is a planned dissolution date.

Registered Agent and Registered Office

A registered agent accepts and sends legal documents on your LLC’s behalf. When you register your Washington LLC, you are required to list your registered agent and your registered office. 

Your registered agent can be anyone 18 years or older that lives in Washington. Your registered agent must always be available at the registered office during regular business hours.

Your registered office address cannot be a P.O. box.

Steps After Your Washington LLC Is Officially Formed

Once you’ve filed your Articles of Organization, you should take the following steps:

Create an Operating Agreement

A Washington LLC operating agreement is a legal document that outlines the ownership structure and member roles of your LLC.

In Washington, you aren’t required to have an Operating Agreement to officially form an LLC, but it's still a good idea to have one. You can start your operating agreement before, during, or after you file your Articles of Organization.

Your operating agreement will be kept in your LLC’s private business records; you do not file it with the state.
Use our free Operating Agreement Tool to draft a customized operating agreement for your LLC.

Get an EIN

An Employer Identification Number (EIN) is like a social security number for your LLC. You will need an EIN if you want to hire employees or open business bank accounts.

You can get your EIN for free through the IRS website, via fax, or by mail. If you would like to learn more about EINs and how they can benefit your LLC, read our What is an EIN article.

Open a Business Bank Account

Using dedicated business banking and credit accounts is essential to protect your business' corporate veil. When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your LLC is sued.

Get Licenses and Permits

When you are registering an LLC, you need to determine if your business needs any licenses or permits to remain compliant. On the federal level, there are a handful of business activities that require licenses or permits.
