What is a Washington Business Entity?

What is a Washington Business Entity

A Washington State business entity is any type of business organization that is legally recognized and registered to operate within the jurisdiction of Washington State, United States.

Like any other U.S. state, Washington State recognizes various types of business entities, which can range from sole proprietorships and partnerships to corporations and limited liability companies (LLCs).

Here are some common types of Washington State business entities:

  1. Sole Proprietorship: An individual owner conducts business as a sole proprietor. This is the simplest form of business entity. The owner has unlimited liability for all business debts and obligations.
  2. General Partnership (GP): Two or more people conduct business together as a partnership. The partners share personal responsibility for all business debts and obligations.
  3. Limited Partnership (LP): This is a business structure that includes general partners and limited partners. General partners manage the business and are personally liable for business debts, while limited partners are only liable up to their investment amount.
  4. Limited Liability Partnership (LLP): This is a partnership that gives all partners some degree of limited personal liability.
  5. Limited Liability Company (LLC): This is a business entity that combines the limited liability benefits of a corporation with the taxation benefits of a partnership. LLCs in Washington are governed by the Washington Limited Liability Company Act.
  6. Corporation (Inc. or Corp.): This is a legal entity separate from its shareholders, offering them limited liability. It can be a C corporation (taxed separately from its owners) or an S corporation (profits and losses are passed through to the owners’ personal tax returns).
  7. Nonprofit Corporation: This is a legal entity created for purposes other than making a profit, such as charitable, educational, scientific, or religious purposes. Nonprofits can apply for tax-exempt status.

Some words cannot be used in a company name. This will require additional paperwork. A licensed person such as a lawyer, doctor or other professional may be required to join the LLC. These words could include:

  • Bank
  • University
  • An attorney

The state has a list of words that cannot be used in the name an LLC. These words are banned because they can cause confusion among federal agencies or states. These words could include:

  • Secret Service
  • FBI
  • Treasury

An LLC is not a corporation so the name of your LLC cannot include the words “corporation”, “incorporated” or any abbreviations.

An LLC name must also be distinguishable. This means that it must be different from any other business registered in Washington.

A business name will not be distinguishable if it has minor modifications. Changes to the grammar or identifiers will not make a business name distinguishable.

  • Some examples of designators include LLC, Inc., L.L.C., and Corp
  • Possessive vs. plural vs. singular grammar
  • The ampersand symbol is used and vs.
  • Spelling numbers out vs. using symbols
  • Modifying or adding punctuation
  • Use of “a” vs. “an” vs. “the”

To ensure that your business name is not already registered, perform a search at the Washington State website. Before you begin the registration process, make sure that the domain name is still available for you to reserve. You may be able to purchase the domain name if you don’t have a business plan.

Once you are familiar with the requirements to create an LLC in Washington, you can begin your search for business entities using the search tool on the Secretary-of-State website.

This website provides information to entrepreneurs and business owners about how they can use the search engine to locate Washington business entities.

This online functionality can be used to search for business purchase documents, general information about business entities, and check the availability of a particular business name.

Basic inquiries can be made using the unified business ID (UBI), or the business name. You can also use advanced criteria to reduce the number of results.

Search by Entity Name

To search for an existing business entity, the first step is to visit the Washington Corporations Search Page. Enter the name you wish to use in the box marked “OrganizationName” and click search. To filter your search results, you can change the default option to “Name starts with”.

You should not include punctuation or business designations, such as LLC and L.L.C. Search for the word “L.L.C.” You don’t need to worry about capitalization in the search bar.

Additional Steps

1. Trademark Search

Entity Trademark Search

When searching for a business name, it’s important to note that availability doesn’t necessarily mean the name is free to use if it’s already a registered trademark.

To avoid potential complications down the line, it’s wise to conduct a thorough trademark search using the Trademark Electronic Search System before finalizing a business name.

2. Choose a Registered Agent

After you have chosen an LLC name that is distinctive and unique, you can now choose your LLC’s Registered Agent.

3. Check if the Domain Name is Available

To check if a domain name is available, you can follow these steps:

  1. Go to a domain registrar website, such as GoDaddy.com or Namecheap.com.
  2. In the search bar on the homepage, type in the domain name you want to check.
  3. Click on the search button to see if the domain name is available or not.
  4. If the domain name is available, you will be prompted to purchase it. If it’s not available, the registrar will suggest some alternative options or you can try a different domain name.

It’s a good idea to check the availability of multiple domain name options as your first choice may already be taken.

Additionally, if you are considering registering a domain name for your business, make sure to also check for any existing trademarks that may conflict with your chosen domain name.

4. Check if Social Media Name is Available

To check if a social media name is available for a new business, you can follow these steps:

  1. Start by choosing a social media platform where you would like to create an account for your business. Some of the popular options include Facebook, Twitter, Instagram, LinkedIn, Pinterest, and TikTok.
  2. Once you have selected the platform, go to the sign-up page and try to create an account using your desired social media name.
  3. If the name is already taken, the platform will display an error message indicating that the name is not available. In this case, you may need to consider alternative names for your social media account.
  4. If the name is available, the platform will allow you to create an account using that name.
  5. It’s important to note that just because a social media name is available, it doesn’t necessarily mean that it’s free to use. You should still do your due diligence to ensure that the name is not already a registered trademark or being used by another business in your industry.

5. Register Washington StateBusiness Entity

When you complete the required documents for filing a new business entity, you then register your business and business name with the state. The state of Washington Statewill either approve your business name or reject it.

I recommend using any of these 3 services to assist you with forming a new business. They can save you time and provide you with guidance through the formation process.

6. Register an Employer ID Number (EIN) With the IRS

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to identify businesses and other entities for tax purposes.

Here’s how you can get an EIN:

  1. Determine if you need an EIN: You’ll need an EIN if you have employees, operate your business as a corporation or partnership, file employment tax returns, have a Keogh plan, or are required to file any of the following tax returns: Employment, Excise, or Alcohol, Tobacco and Firearms.

  4. Wait for your EIN: If you apply online, you can receive your EIN immediately after completing the application. If you apply by fax or mail, it can take up to four weeks to receive your EIN.

Note that there is no fee to apply for an EIN. Once you receive your EIN, be sure to keep it safe and use it on all tax documents and forms.
