Starting an LLC in Colorado

LLCs in Colorado are affordable and easy to form. As with other states, the State of Colorado has some unique LLC requirements.

Interested parties must register with the Colorado Secretary of State by filing the necessary forms, paying the necessary fees and meeting all naming and formation requirements.

The specifications required of a Colorado LLC are:

Registration. LLCs are required to file Articles of Organization with the Secretary of State. The documents may be submitted online. The Articles of Organization must include the following information:

  • LLC’s name and principal office address

  • Registered agent’s name and address

  • Effective date, if other than the date filed

  • Management type, i.e. member-managed or manager-managed

  • Organizer’s name, address and dated signature

All forms must be submitted with the necessary filing fee.



Forms and fees. LLC registrants are required to complete and submit Articles of Organization to the Secretary of State. There is a filing fee that must be paid upon submission of the documents. There is an expediting fee for paper-filed documents. There is no expediting fee for documents filed online.

Timeline. Documents submitted online are processed in real time immediately after they are submitted and may take between seven to 10 business days to be approved or rejected. Should you opt for expedited services, processing time is within three business days.

Naming requirements. LLC naming requirements can be confusing. However, the easiest way to make sure that your LLC name will be approved is to make sure that it is distinguishable from other LLCs and includes specific words required of LLCs. You may opt to have a preferred name checked for availability before filing your LLC formation documents with the Secretary of State.

Formation requirements. To form an LLC, a registrant must first file their Articles of Organization with the Secretary of State. All submissions must be accompanied by the required filing fee.

An LLC with more than one member is also strongly advised to have a limited liability operating agreement among its members.

Please take note that LLCs offering a specific professional service are obligated to contact the necessary licensing boards as mandated by state law.

Starting an LLC in Colorado

Before you begin the LLC registration process for an LLC in Colorado, it’s important to know what an LLC is and whether or not it is a viable business structure for your company, so be certain to read up on the definition and benefits of an LLC .

Here are some tips to help you put together what you need to begin the registration process with the Secretary of State:

1. Decide on a name for your business. You can choose any name as long as it ends with “Limited Liability Company,” “Limited,” “Ltd. Liability Company,” “Limited Liability Co.,” “Ltd. Liability Co.” or any variant of its abbreviations—e.g., L.L.C., LLC or Ltd. Co.

Names may be reserved for up to 120 days. A Statement of Reservation of Name may only be filed online with the Secretary of State and requires a small filing fee. Be sure to include in the application the name to be reserved and the applicant’s name, address and dated signature.

Prior to filing a name reservation application, you may have the preferred name checked for availability.

2. Assign an agent for service of process. This is also referred to as the resident agent.

3. Get an Employer Identification Number (EIN) from the IRS. If there are two or more members in your LLC, your company will need to obtain an EIN from the IRS, for tax purposes.

4. Create an operating agreement. Although LLCs in Colorado are not required to have a limited liability company operating agreement, it is wise to have one in place with other members should your LLC have more than one member. The State of Colorado recognizes limited liability company operating agreements as governing documents.  

5. Familiarize yourself with the LLC’s continuing legal obligations. These continuing legal obligations vary with each state.
