Why Create a Colorado LLC?

Within the state of Colorado, business owners can take advantage of several programs and funding made available by the Colorado Office of Economic Development and Industrial Trade, provided your LLC meets the specific criteria. For example, Colorado microloans are made available to small businesses requiring access to capital, ranging from $5,000 to $50,000.

For entrepreneurs looking to start a business in Colorado, creating a Colorado limited liability company (LLC) is generally the fastest and easiest way. With more simplified rules and regulations, an LLC is an ideal business entity for startups and small to medium-sized businesses, granting you the advantages and protections that larger Colorado corporations benefit from.

If an LLC isn't the right entity for the type of business you're starting, you may want to consider forming a Colorado Corporation instead.

Benefits of starting a Colorado LLC:

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

  • Create, manage, regulate, administer, and stay in compliance easily

Learn more about the benefits of the LLC business structure.

In this guide, you’ll find information on naming your LLC, getting a Registered Agent, the fees you’ll need to pay, Colorado business taxes and much more. We also cover your registration needs, filing your Colorado LLC and how you'll correspond with the Colorado Secretary of State (SOS).

How to Form an LLC in Colorado Yourself in Six Steps

Start an LLC

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

To start the process, you’ll need a name for your LLC that’s unique and stands out, but one that’s not used by any other business or formed entity in the state. If you’re having trouble coming up with a name, try using Bizee’s Business Name Generator to brainstorm ideas. You'll also need to follow a few naming rules, which you can read about in detail on the Colorado Business Names page.

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

Step 2: Provide an Official Business Address for your LLC

Regardless of whether your business is in an office building, a home (if the company is run from a residence) or any other physical location, every Colorado LLC must have a designated street address. It can be located outside the State of Colorado, but it cannot be a P.O. Box.

Step 3: Assign a Registered Agent

A Registered Agent is someone who receives official legal and tax correspondence and is responsible for filing reports with the Colorado Secretary of State (SOS). Every LLC in Colorado 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 Colorado Registered Agent is a person, they must have a physical street address in Colorado and must be present during business hours to receive important documents on behalf of your business. In Colorado, you 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 Colorado Secretary of State

Once you've gathered all the information for your Colorado LLC, you’ll need to file your Articles of Organization with the Colorado SOS.

The certificate must include:

  • Name of your LLC
  • Principal office address (both street and mailing)
  • Registered Agent and contact information
  • Whether the LLC is member-managed or manager-managed
  • Name(s) and address(es) of organizer(s)

Your Articles of Organization must be filed online by using an integrated filing system on the Colorado SOS website. The Colorado LLC filing fee is $50.

You only need to file your Articles of Organization once, but you must file an annual report every year. The periodic report must be filed online, and the filing fee for an annual report, set by the CO Secretary of State, is $10. 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 you can have Bizee obtain one for you as part of the Colorado LLC formation process.

Step 6: Create an Operating Agreement

A kind of "instruction manual" that explains how you'll run your business, an LLC Operating Agreement details key components of your business — how decisions will be made, how the business is divided among members and what will happen if a member leaves the company.

Although some states require that a company have this document in place, you're not legally required to have a Colorado Operating Agreement. We think it’s still a good idea to have one regardless.

Other Colorado LLC Types

Professional LLC

Professional Limited Liability Companies (PLLCs) are different from professional corporations in that they typically have licensing requirements applicable to certain fields, such as law and medicine. In order to form a PLLC, you may need a state license to practice.

Learn more about PLLC vs. LLC and which one is right for your business.

Foreign LLC

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