Why Create a Washington LLC?

The state of Washington Department of Revenue offers over 50 tax incentive programs for businesses, provided your LLC meets specific criteria. For example, if you start a business that provides international services, you may qualify for a tax credit of up to $3000 for every employment position you fill with employees from the Community Empowerment Zone (CEZ) or designated International Services District. If the employment position is maintained, an additional $3000 credit can be taken in each of the four following years.

For most entrepreneurs wanting to start a business, creating a Washington limited liability company (LLC) is the fastest and easiest way. An LLC is an ideal business entity for startups and small to medium-sized businesses, giving you access to the advantages and protections that larger Washington corporations benefit from, but with simplified rules and regulations.

The Benefits of Starting a Washington LLC:

  • Protect your personal assets from your business liability and debts

  • Simple to create, manage, regulate, administer, and stay in compliance

  • Easily file your taxes and discover potential advantages for tax treatment

Learn more about the benefits of an LLC business structure. In this guide, you’ll find all the information you need on naming your LLC, getting a Registered Agent, the fees you’ll need to pay, Washington business taxes, and much more. We’ll also cover how you'll interact with the Washington Secretary of State (SOS), and what you'll need to register and file your Washington LLC.

How to Form a Washington LLC Yourself in Six Steps

Start an LLC

Step 1: Complete a Washington LLC Search and Choose a Unique Business Name

You’ll need a distinctive and original name for your LLC that’s not used by any other business in the state, whether your business is in Seattle or Tacoma or any city. If you’re having trouble coming up with a name, try using Bizee’s Business Name Generator to brainstorm ideas. You'll need to follow a few naming rules, which you can read about in detail on the Washington Business Names page.

Once you’ve chosen a name, you’ll need to make sure it’s available in Washington. To find out whether another company in the state is using your chosen business name, use our tool to do a business name search. You can also carry out a name search on the Washington Secretary of State online database.

Step 2: Provide an Official Business Address for your LLC

Every Limited Liability Company (LLC) conducting business in the state of Washington must have a designated street address, whether it’s an office building, a home, or any other physical location. The address can be outside the state of Washington, but it cannot be a P.O. Box.

Step 3: Assign a Registered Agent

Someone who receives official legal and tax correspondence and is responsible for filing reports with the Washington Secretary of State is called a Registered Agent.

Every LLC in Washington is required to have a Registered Agent. This position can be filled by you, another manager in your business, or a dedicated Registered Agent service. If your Washington Registered Agent is a person, they must have a physical street address and reside in Washington, and must be present during business hours to receive important documents on behalf of your company. In Washington, you are required to appoint your Registered Agent when you file your Articles of Organization and formally create your business.

All of Bizee’s packages include Registered Agent service. It’s free for the first year and just $119 per year after that. You can also log in to our dashboard and easily view any document we've received on your behalf.

Step 4: File Your Articles of Organization with the Washington Secretary of State

Once you've gathered all the information for your Washington LLC, you’ll need to file a form with the Washington SOS or register an account, complete it online and pay an additional $20 online filing fee.

The articles must include:

  • Unified Business Identifier (UBI)
  • Entity Name
  • Period of duration (can be indefinite)
  • Effective date
  • Registered agent and contact information
  • Principal office address
  • Return address for the filing
  • Executor information and signature

Your Articles of Organization can be filed online for an additional online filing fee of $20 with the Washington Secretary of State Corporations and Charities Division, you can mail them to the Office of the Secretary of State, or you can have Bizee do it on your behalf. The Washington LLC filing fee is $180.

File by Mail

Washington Secretary of State Corporations and Charities Division

801 Capitol Way

S Olympia, WA 98501-1226

You only need to file your Articles of Organization once, but every year after, you must file an annual report. The fee for this, set by the Washington SOS, is $60. Bizee can either remind you to do it, or we can do it for you.

Step 5: Get an Employer Identification Number (EIN) from the Internal Revenue Service

You’ll need an EIN to identify your business to the IRS. You use this number when filing and paying taxes or when submitting payroll information and payments for your employees. An EIN is also required to open a business bank account. You can obtain one directly from the IRS, or Bizee can get one for you as part of the Washington LLC formation process.

Step 6: Create an Operating Agreement

An LLC Operating Agreement details how decisions will be made, how the business is divided among members, and what will happen if a member leaves the company. Think of it as a kind of “instruction manual” that explains the inner workings of your business.

Some states require that a company have this document in place. You're not legally required to have a Washington LLC Operating Agreement, but it’s a good idea to have one nonetheless.

Other Washington LLC Types

Professional LLC

Different from professional corporations, Professional Limited Liability Companies (PLLCs) typically have licensing requirements applicable to certain fields, such as law and medicine.

In order to form a Washington PLLC, you need to:
  • Have the state license for each professional who will be a member of the PLLC
  • Check with the state licensing board for your profession to see if its prior approval is required (and, obtain the necessary documentation showing that approval)
  • File a certificate of formation with the Washington Secretary of State (SOS).

Foreign LLC

If your business is already operating in another state and expanding to Washington — or vice versa — you’ll need to form a Foreign LLC.
