1. 1Choose a name for your LLC and verify availability by searching the Colorado Secretary of State business database. Your name must include "Limited Liability Company," "LLC," or "L.L.C."
2. 2Appoint a registered agent with a physical street address in Colorado (P.O. boxes are not accepted).
3. 3File Articles of Organization online with the Colorado Secretary of State. The filing fee is $50. Colorado only accepts online filings — there are no paper forms. Processing is typically same-day.
4. 4Obtain an EIN (Employer Identification Number) from the IRS at no cost.

Your Colorado LLC name must contain "Limited Liability Company," "LLC," or "L.L.C." The name must be distinguishable from all other business entities on file with the Colorado Secretary of State. Restricted words like "Bank," "Insurance," or "University" may require additional licensing. Colorado is relatively lenient on naming conventions compared to other states.

Colorado LLCs are pass-through entities. Members pay Colorado individual income tax at a flat rate of 4.4% on their share of LLC profits. Colorado does not impose a franchise tax or entity-level tax on LLCs. The annual Periodic Report costs just $10, making Colorado one of the cheapest states for ongoing compliance.

LLC vs. other structures in Colorado

Colorado is one of the best value states for LLC formation: $50 to file, same-day processing, and only $10/year to maintain. Total first-year cost is just $60. This makes Colorado an excellent choice for small businesses. An S-Corp election makes sense if profits exceed $50,000-$60,000 annually to reduce self-employment taxes.

• •File a Periodic Report online during your anniversary month — just $10
• •Maintain a registered agent with a physical address in Colorado at all times
• •Keep your operating agreement current and update it when membership changes
• •File Colorado state income tax returns for all members receiving pass-through income
• •Renew any local business licenses or permits as required by your city or county

Colorado offers a reasonable cost structure for LLCs. The $50 filing fee is competitive, and ongoing costs are manageable. If you operate in Colorado, forming your LLC here makes the most sense.

In general, you should form your LLC in the state where you physically live and conduct business. Forming in a "tax-friendly" state like Wyoming, Delaware, or Nevada sounds appealing, but if you operate in Colorado, you will still need to register as a foreign LLC there — paying fees in both states.

An LLC is almost always a better choice than operating as a sole proprietorship because of the personal liability protection it provides. However, if your LLC is highly profitable, you should talk to a CPA about electing S-Corp tax treatment to potentially reduce your self-employment tax burden.
