When starting a business in Colorado, one has many options. One can be a sole proprietor, a partnership, incorporate, or choose to become a Limited Liability Company or LLC. Limited Liability Companies combine many of benefits a sole proprietorship has, such as simplicity and taxes but provides the legal protection that a corporation affords. Forming an LLC has certain requirements specific to Colorado. Here’s how to start an LLC.

Getting Started

As the prospective owner of a new business, it’s important to understand what the company does and how its name will reflect on it. Company names are a form of branding, which is why it is important to create a name that describes the products as well as the vision of the owner. The prospective LLC owner will need to name the LLC and establish the registered agent. The prospective owner or member must then file the articles of organization and pay the fee.

Naming the LLC

Spend some time considering what the company name will be.  This will often be the client’s or customer’s first impression of the company.  Choose a name that is not registered in Colorado, nor can it be a name of a state or federal agency. Choose a name that has an available domain name so that the domain name can be registered to the company.

Naming Guidelines in  Colorado

When naming a company it must contain the words “Limited Liability Company,” “LLC,” or “L.L.C.”  This is included so it is obvious what type of company the name represents. As said above, the name must be unique and not taken by another company in Colorado. Unless the company is a particular type of company, such as a bank, or if the company has licensed individuals such as lawyers or doctors, the owner cannot choose the restricted words that would identify the business as such. Should the owner choose to use these words. the State of Colorado will require additional paperwork.

As stated above, the prospective LLC owner cannot use prohibitive words such as the names or acronyms or state and federal agencies.

Before submitting a name, the prospective LLC owner or member should see if the name is available in Colorado.  The prospective owner  should navigate online to Name Search and enter the name.  If no name appears in the search, it may be available.

Is the domain name available?

All businesses should have an Internet presence with a unique domain name. Now is the time to reserve the domain name.  Many registrars can help the prospective business owner look to see if the domain name is available. Choose the name and suffix that fits the LLC.

Select a Registered/ Statutory Agent

The next step is selecting a registered/ statutory agent.

What is a Registered Agent?

A registered agent is the point of contact for the LLC to the State of Colorado. The registered agent will have a registered street address so the State of Colorado can send official information to the LLC.
