Colorado LLC cost FAQ
How much does it cost to start an LLC in Colorado?
The one-time Articles of Organization filing fee in Colorado is $50. The recurring cost is $25/year ($25 periodic report, due by end of the 2nd month after your formation anniversary month). An EIN from the IRS and writing your own operating agreement are both free. Verify the current fee with the Colorado Secretary of State (or equivalent) before filing.
Is a registered agent required, and does it cost extra in Colorado?
Yes, Colorado requires an LLC to have a registered agent, but you can act as your own at no cost if you have a physical address in the state and are available during business hours. A registered agent service typically runs about $100–$150 per year if you'd rather not use your own address.
What's the cheapest way to form an LLC in Colorado?
Filing the Articles of Organization yourself directly with the state and acting as your own registered agent costs only the $50 state filing fee — no formation-service markup. A paid formation service adds convenience, not anything you can't do yourself. Verify the current fee with the Colorado Secretary of State (or equivalent) before filing.
