Step 1: Name Your Colorado LLC

Choosing a company name is the first and most important step in forming your Colorado LLC. Be sure to choose a name that complies with Colorado naming laws and requirements and is easily searchable by potential business clients.

1. Follow the naming guidelines for a Colorado LLC:

  • Your name must include the phrase “limited liability company” or one of the following abbreviations or words: “LLC, L.L.C., ltd., limited liability co., ltd. liability company, ltd. liability co., or limited.”
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • Restricted words (e.g. Bank, Attorney, University) may require additional legal paperwork and a licensed individual, such as a doctor or lawyer, to be part of your LLC.

2. Is the name available in Colorado? Make sure the business name you want isn't already taken by doing a name search online through the Colorado Secretary of State Business Database Search.

To learn more about searching for a Colorado LLC name, read our full guide. Find name ideas using our free LLC name generator.

3. Is the URL available? We recommend that you check online to see if your business name is available as a web domain. Even if you don't plan to make a business website today, you may want to buy the URL in order to prevent others from acquiring it.

Do I need to get a DBA or trade name for my business?An orange arrow pointing down

Most LLCs do not need a DBA, known in Colorado as a trade name. The name of the LLC can serve as your company’s brand name and you can accept checks and other payments under that name as well. However, you may wish to register a DBA if you would like to conduct business under another name.

To learn more about DBAs in your state, read our How to File a DBA guide.

Step 2: Choose a Registered Agent in Colorado

You are required to appoint a registered agent for your Colorado LLC.

What is a registered agent? A registered agent is an individual or business entity responsible for receiving important tax forms, legal documents, notice of lawsuits, and official government correspondence on behalf of your business. Think of your registered agent as your business's point of contact with the state.

Who can be a registered agent? A registered agent must be a full-time resident of Colorado or a corporation, such as a registered agent service, authorized to conduct business in the state of Colorado. You may elect an individual within the company, including yourself.

Step 5: Get a Colorado LLC EIN

You can get an Employer Identification Number (EIN) from the IRS for free. It is used to identify a business entity and keep track of a business’s tax reporting. It is essentially a Social Security number (SSN) for the company.

  • To open a business bank account for the company
  • For federal and state tax purposes
  • To hire employees for the company

Where do I get an EIN? An EIN is obtained from the IRS (free of charge) by the business owner after forming the company. This can be done online or by mail.
