How to Start an LLC in Colorado


Located on the edge of the Great Plains and home to most of the southern Rocky Mountain range, Colorado is a state that’s full of natural beauty. Colorado boasts a rich culture, diverse landscapes and a thriving tourism industry, and it is recognized as one of the best states in the nation for business.

Though Colorado is an agricultural powerhouse, it also features diverse industrial and service sectors. Scientific and high-tech businesses are well-represented in The Centennial State.

If you want to start your own business in Colorado, one of the best ways to do so is by forming a Colorado LLC. Limited Liability Companies (LLCs) are a business entity designed for startups and small- and medium-sized businesses. Colorado LLCs give you many of the protections and advantages of larger corporations without all the rules, regulations and compliance issues common to larger business entities.

Briefly, the benefits of starting a Colorado LLC include:

  • Separating and limiting your personal liability from your business liability and debts
  • Quick and simple filing, management, compliance, regulations and administration of your Colorado LLC
  • Easy tax filing and potential advantages for tax treatment

Six Quick Steps for Forming Your Colorado LLC

We’ve got lots of useful information on starting a business in CO. On this page you’ll find the basic steps of how to form a Colorado LLC, with more in-depth content throughout the rest of our guide.

STEP 1: Gather Information for Your Members

First, you need to gather basic information about your LLC, including the names and addresses of the managers or members.

The LLC members are typically the people who own and run the business. They are also the ones who can take profits out of the business to pay themselves.

STEP 2: Search for and Choose a Unique Business Name for Your Colorado LLC

You will need a distinctive and original name for your Colorado LLC that’s not used by any other business in CO. To find out if another company is using your chosen business name, carry out a Colorado business entity name search on the CO Secretary of State website.

There are a few rules you’ll need to follow when choosing an LLC name. You can find out more in our guide to searching for and naming your Colorado LLC.

Learn about Colorado LLC business naming rules.

STEP 3: Provide an Official Address for Your CO LLC

Every Colorado LLC must have a designated street address. That could be your home address (if you’re running the company from your residence), your company’s office building or any physical address of your preference. The address can be outside the state of Colorado and can be a P.O. Box.

STEP 4: Assign a Registered Agent for Your Colorado LLC

Every CO LLC must have a “Registered Agent” when it is formed. This is an official position; the Registered Agent is someone who receives official legal and tax correspondence and has responsibility for filing reports with the Colorado Secretary of State.

This position can be filled by you, another manager in the business or a dedicated Registered Agent service. Your CO Registered Agent must have a physical street address in Colorado and must be present to receive important documents for your company during business hours.

At Incfile, all of our packages include a Colorado Registered Agent service that is free for the first year and just $119 per year afterward. We also have a dashboard where you can log in and easily view any document your Registered Agent has received on your behalf.

STEP 5: Get an Employee Identification Number (EIN) from the Internal Revenue Service

You will 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. You can obtain one directly from the IRS, or we can get one for you as part of the Colorado LLC business formation process.

STEP 6: File Articles of Organization with the Colorado Secretary of State

Once you've gathered all the information for your Colorado LLC, you’ll need to file a formal document with the CO Secretary of State. This document is known as your “Articles of Organization,” and filing the document creates your Colorado LLC. Here’s what is typically included:

  • Your business name and address
  • Details of your Registered Agent
  • Names of managers or members of the LLC at the time of filing
  • Addresses of managers or members of the LLC at the time of filing
  • Name of the incorporator

You can file your Colorado LLC Articles of Organization online, mail in a form or have Incfile do it on your behalf. There is a fee to file and start an LLC in Colorado. You only need to file your Articles of Organization once.
