How to start an LLC in Colorado
Pick a name and check it is available with the Secretary of State.
Choose a registered agent with a physical Colorado address: an adult with a Colorado home or usual place of business, or a business in good standing with a Colorado place of business. The Secretary of State cannot be your agent.
File Articles of Organization online and pay $50.
Get an EIN from the IRS. It is free.
File the periodic report ($25) each year, from 2 months before to 2 months after your periodic report month.
Fee $25 (since July 1, 2024). File from 2 months before to 2 months after the periodic report month shown on your entity's summary page. The late penalty is $50.
Be careful here. The Secretary of State's registered agent changes page (rules effective July 1, 2025) says an entity can serve as its own registered agent only through a two-step change after it registers. An older state checklist says the LLC can serve as its own agent. Official pages conflict, so check with the Secretary of State before relying on either.
Changing your registered agent is a $10 state filing.
