How to File
Choose a Name for Your LLC
Select a unique business name that includes 'Limited Liability Company,' 'LLC,' or 'L.L.C.' and does not conflict with existing Colorado business names. Use the Colorado Secretary of State's free name search tool at bizfilecolorado.gov to verify availability before filing.
30 minutes
Designate a Registered Agent
Appoint a registered agent with a physical street address in Colorado (P.O. boxes are not permitted) who is available during normal business hours to receive legal documents on behalf of your LLC. The registered agent can be an individual Colorado resident or a commercial registered agent service.
15 minutes
File Articles of Organization
Submit your Articles of Organization online through the Colorado Secretary of State's bizfilecolorado.gov portal and pay the $50 filing fee. You will need to provide your LLC name, principal office address, registered agent name and address, and the names of the persons forming the LLC.
20 minutes
Draft an Operating Agreement
Although not legally required by Colorado law, drafting an Operating Agreement is strongly recommended to define ownership structure, member roles, profit distribution, and management procedures. This internal document helps prevent disputes and is often required by banks when opening a business account.

What's Next After Filing
Once your LLC is officially formed, you'll want to complete these important steps:
- •Obtain an EIN from the IRS — Apply for a Federal Employer Identification Number (EIN) from the IRS at irs.gov/ein at no cost — this is required for hiring employees, opening a business bank account, and filing federal taxes. Single-member LLCs with no employees may use the owner's SSN, but an EIN is still recommended for liability protection.
- •Register for Colorado State Taxes — If your LLC will sell taxable goods or services, or hire employees, register with the Colorado Department of Revenue through MyBizColorado at mybiz.colorado.gov to obtain the necessary sales tax license and/or employer withholding accounts. Colorado has no state-level franchise tax or gross receipts tax for LLCs.
- •File the Periodic Report (Annual Report) — Colorado requires all LLCs to file an annual Periodic Report with the Secretary of State, due during the three-month window beginning on the first day of the anniversary month of your LLC's formation, with a $10 filing fee. The report confirms or updates your LLC's current registered agent and principal office information.
Advantages
- ✓Very low formation cost at $50 and one of the lowest annual report fees in the nation at $10 per year, making Colorado highly affordable for small businesses.
- ✓No state franchise tax or minimum annual tax, unlike states such as California ($800 minimum) or Delaware, reducing the ongoing cost burden on LLC owners.
- ✓Colorado's online bizfilecolorado.gov portal makes formation and ongoing compliance fast, easy, and fully digital with typical 1-2 business day processing.
- ✓Strong liability protection separates personal assets from business debts and legal obligations, and Colorado law supports single-member LLCs with full limited liability protections.
- ✓Flexible management structure allows LLCs to be member-managed or manager-managed, with no residency requirements for members or managers in Colorado.
Considerations
- •Colorado's $50 base filing fee, while reasonable, is higher than a handful of states (e.g., Kentucky at $40 or Missouri at $50) and lacks a free or reduced-fee option for micro-businesses.
- •Colorado requires a registered agent with a physical in-state address at all times; if you operate remotely or out of state, you must hire a commercial registered agent service, typically costing $50–$150 per year.
- •Colorado LLCs with multiple members or complex ownership structures should invest in a thorough Operating Agreement, which, while not legally required, can be costly to draft professionally and creates risk if skipped.
