The 4 steps in Colorado
Pick a name that works in Colorado
Your name must be distinguishable from other Colorado businesses and end in a designator like “LLC” or “Limited Liability Company.” Search the state's business database before you file.
File the paperwork
Colorado is online-only for LLC formation — there's no paper form. You file directly on the Secretary of State's website, which keeps things fast and cheap. The filing fee is $50. Also write a simple operating agreement — it's free, and it keeps your liability protection clear.
Get your free EIN
Apply at IRS.gov and get your Employer Identification Number immediately, for free. You'll need it for taxes and your business bank account.
Open a business bank account
Bring your approved Articles of Organization, EIN, and operating agreement. Keeping business money separate is what makes the liability protection hold.
Optional: name a registered agent service
Every Colorado LLC needs a registered agent with a physical address in the state. You can be your own for free — or pay a service to keep your address private. Learn how registered agents work.
Colorado is one of the cheapest and fastest states to form an LLC in, and its $25 annual report is among the lowest ongoing costs in the country.
