Colorado lesson 3 of 6
File the Articles of Organization
Colorado does not accept a paper Articles of Organization for a standard domestic LLC. Everything goes through the Secretary of State's online filing system for a $50 fee.
What the filing asks for
The Articles of Organization cover the entity name, the principal office address, the registered agent's name and Colorado address, whether the LLC will be managed by managers, and the name and address of at least one person causing the filing to be delivered.
- The filing system checks the name for availability before you can proceed
- You do not need to list every member; management structure is disclosed instead
- A delayed effective date can be set if you do not want the LLC to exist until a later date
Speed and cost
The state fee is $50 and there is no separate paper option or mail-in fee tier to compare it against. Because filing is entirely online, most Articles of Organization are reviewed and approved within minutes of submission rather than sitting in a multi-day queue.
Key takeaways
- Articles of Organization must be filed online; there is no paper route.
- The state fee is $50.
- Approval is typically immediate once the online filing is submitted.
Frequently asked questions
Can I mail in Colorado's Articles of Organization?
No. Colorado requires online filing for a standard domestic LLC formation, so a mailed paper document is not accepted for this filing.
Do I need to list all LLC members in the Articles?
No. The form asks whether the LLC is managed by managers and for the registered agent and a contact person, not a full membership list.
