Step-by-Step: Forming an LLC in Colorado

Eight Steps to Legal Operation

Colorado offers a streamlined, online-first process. Here's the practical roadmap:

1. Choose a Compliant Name

Must include "Limited Liability Company," "LLC," or "L.L.C." Check availability via the Secretary of State's database. Reserve for 120 days ($25) if not ready to file.

2. Appoint a Registered Agent

Individual or entity with a physical Colorado address (no P.O. boxes) available during business hours to accept legal mail. Can be yourself, a member, or a commercial service ($50–$300/yr).

3. File Articles of Organization

Submit online only at sos.state.co.us. Fee: $50. Required info: LLC name, principal address, registered agent, management type (member-managed or manager-managed), organizer's name/address. Processing: immediate.

4. Create an Operating Agreement (Highly Recommended)

Internal document governing ownership %, profit/loss allocation, voting, membership changes, dissolution. Not filed with the state. Single-member LLCs still benefit for liability protection and banking.

5. Obtain an EIN (Federal Tax ID)

Free, instant online via IRS. Required for hiring, opening a bank account, and filing taxes (even if no employees).

6. Open a Business Bank Account

Bring: Articles of Organization (stamped), Operating Agreement, EIN confirmation, ID. Keeps personal and business finances separate—critical for liability protection.

7. Register for State Taxes

• Sales Tax License: If selling tangible goods or taxable services. Register via Revenue Online.
• Withholding/Unemployment: If hiring employees.
• Periodic Tax: Annual Periodic Report due each year ($10 online).

8. Secure Insurance & Licenses

• General Liability, Professional Liability, Workers' Comp (mandatory with employees).
• Check DORA for industry-specific licenses (construction, food, childcare, etc.).
• Local (city/county) business licenses may apply.

Pro Tip

Colorado has no franchise tax and no annual report fee beyond the $10 Periodic Report. The entire formation can be done in one afternoon for ~$100–$200 (state fees + registered agent if commercial).
