3Registered Agent Requirements
Colorado requires all LLCs to maintain a registered agent.
Can You Be Your Own Registered Agent?
Yes, you can serve as your own registered agent in Colorado.
Requirements: An individual agent must be 18+ with a primary residence or usual place of business in Colorado and a physical Colorado street address (no P.O. box or commercial/CMRA address); effective July 1, 2025 (HB 24-1137) an individual agent must also provide a valid Colorado driver's license/state ID number or complete alternate verification. An entity agent must be registered in Colorado and in good standing. The agent must consent.
4Foreign LLC Registration
If your LLC was formed in another state but you want to do business in Colorado, you'll need to register as a foreign LLC.
Foreign LLC Registration
- Registration Fee: $100
- Requirements: File the Statement of Foreign Entity Authority and designate a Colorado registered agent with a physical Colorado address. Colorado does not require a certificate of good standing/existence from the home state, though the LLC must still be in good standing back home.
5Colorado LLC Taxes
Colorado has a flat 4.4% state income tax rate (2024). LLCs taxed as pass-through entities pass income to members.
6Penalties for Non-Compliance
Late Filing Penalties
$50 late filing penalty after the periodic-report window closes (status goes Noncompliant, then Delinquent). Curing delinquency costs $100 (Statement Curing Delinquency). Fee was raised from $10 to $25 on July 1, 2024.
Administrative Dissolution Risk
Dissolution only after an entity is delinquent 3+ years. A $100 Statement Curing Delinquency (or $100 Articles of Reinstatement if already dissolved) restores good standing.
Key Considerations for Colorado LLCs
- Very low formation fee of $50
- Low periodic report fee of $25 (raised from $10 effective July 1, 2024)
- Simple online filing through Colorado Secretary of State
- Growing tech and startup ecosystem
