How to form an LLC in Colorado

Colorado LLCs are formed by filing Articles of Organization with the Colorado Secretary of State — the official filing fee is $50 (see the fee notes below). Corpus prepares and files it for $250 all-in, including your first year of registered-agent service.

What you’ll need

The Corpus intake collects this information to prepare the filing. Some questions are asked only when they apply — for example, the management question is asked only when the company has more than one owner.

  • What do you want to name the company?
  • In a sentence, what will the business actually do?
  • Where should official mail go — street, city, state, ZIP?
  • What email should we use for this order?
  • Which industry code fits this business?
  • Besides you, will anyone else have authority to make decisions for the business?
  • Who owns this company?

Colorado asks nothing beyond the standard questions.

Form it with your AI agent

You don’t have to do the intake here. Any agent that can open a link can run the whole thing — Corpus’s formation tools give it Colorado’s requirements and live price, it asks you the questions above, and it hands back a prefilled link you review and pay. Paste this into your assistant:

Form an LLC in Colorado for me with Corpus (corpuslaw.us). Use its formation tools to get Colorado's requirements and price, ask me what you need, and give me the prefilled link.

The guide is on /agents, the protocol reference is /docs/mcp, and the installable skill for this state is the Colorado SKILL.md.

Every verified fact above names where Corpus read it and the date it was last verified. Sources marked secondary are third-party write-ups used only where an official page did not publish the answer.

Corpus is not a law firm and does not provide legal advice. Fees and rules change — each verified fact above shows the date Corpus last verified it; anything marked “not yet verified” should be confirmed with the filing office.
