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.
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.
Once you have verified your name is available, you may now select a professional service to complete the LLC formation process for you.

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 3: File Your Colorado LLC Articles of Organization
To register your Colorado LLC, you will need to file the Articles of Organization with the Colorado Secretary of State. You can only apply online.
Now is a good time to determine whether your LLC will be member-managed vs. manager-managed.
For help with completing the form, visit our Colorado Articles of Organization guide.
If you’re expanding your existing LLC to the state of Colorado, you will need to form a foreign LLC.
Step 4: Create Your Colorado LLC Operating Agreement
An operating agreement is not required for an LLC in Colorado, but it's a good practice to have one.
What is an operating agreement? An operating agreement is a legal document outlining the ownership and operating procedures of an LLC.
Why are operating agreements important? A comprehensive operating agreement ensures that all LLC owners are on the same page and reduces the risk of future conflict.
For more information on operating agreements, read our Colorado LLC operating agreement guide.

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.
Why do I need an EIN? An EIN number is required for the following:
- 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.
FOR INTERNATIONAL APPLICANTS: You do not need an SSN to get an EIN. Learn more here.
