Form an LLC in Colorado — or trade today with a ready-made one

Colorado is one of the most underrated states for LLC formation. A $50 online filing fee, a remarkably low $10/year periodic report, and same-day processing make it excellent value — and the Centennial State has quietly built one of the strongest tech ecosystems outside Silicon Valley, with startups clustered around Denver, Boulder and Colorado Springs.

You absolutely can form a Colorado LLC yourself, and this page walks you through every step. But forming the company is only half the job: you still have to apply to the IRS for an EIN, and until that EIN lands, no bank or payment processor will fully onboard you. For founders who need to invoice this week, a ready-made Wyoming LLC that already has its EIN removes that wait entirely.

All fees below are sourced from the Colorado Secretary of State fee schedule.

Step 1 — Choose your LLC name

Search for available names on the Colorado Business Entity Search. Your name must include "Limited Liability Company," "LLC," "L.L.C.," or an abbreviation. Colorado does not offer name reservation for LLCs — the name is secured when you file.

Step 2 — Appoint a registered agent

Every Colorado LLC must have a registered agent with a physical street address in Colorado. The agent must be available during normal business hours. You can serve as your own agent if you have a Colorado address.

Step 3 — File Articles of Organization

File online through the Colorado Secretary of State. Online filing is recommended (cheaper and faster). The filing requires:

• LLC name with designator
• Principal office address
• Registered agent name and Colorado address
• Management structure (member-managed or manager-managed)
• Name and address of at least one person forming the LLC
• $50 filing fee (online)

Colorado's Articles of Organization are straightforward and can be completed in minutes. The online system is well-designed and user-friendly.

Step 4 — Create an Operating Agreement

Not required by Colorado law, but essential for banking, tax compliance, and internal governance. We include a custom Operating Agreement in every formation package.

Step 5 — Obtain an EIN

Apply for an EIN from the IRS. Standard process for all states. Online application available for those with an SSN; fax/mail for non-residents. This is the step that gates banking — and the one a ready-made LLC has already cleared.

Step 6 — Register for Colorado taxes (if applicable)

If you will sell taxable goods or services in Colorado, register with the Colorado Department of Revenue for a sales tax account. Colorado has a destination-based sales tax system, which can be complex due to varying local rates.

Annual compliance requirements

1. Periodic report: Due during your LLC's anniversary month each year. Fee: $10 (online). Filed through the Colorado Secretary of State website. Failure to file results in delinquent status and eventually administrative dissolution.
2. Federal tax filing: Form 5472 with pro forma 1120 for foreign-owned LLCs. Due April 15.
3. Colorado income tax: If you have Colorado-sourced income, file a Colorado income tax return (4.4% flat rate).
4. Sales tax returns: If registered for Colorado sales tax, file returns on the required schedule.
5. Registered agent: Maintain a registered agent with a physical Colorado address.
6. FinCEN BOI Report: Required under the Corporate Transparency Act.

Colorado taxes for LLCs

For non-residents with no Colorado-sourced income, the only annual state cost is the $10 periodic report. Colorado's 4.4% income tax only applies to income earned within the state. If your business has no Colorado nexus, a Wyoming LLC avoids state income tax altogether.

Processing times

Colorado's online processing is among the fastest in the US. Most online filings are approved within hours, often the same business day — faster than Wyoming (1–3 days) and significantly faster than Delaware (3–5 days). Even so, fast formation doesn't fast-track the EIN — which is why a ready-made company stays the quickest route to actually trading.

Every formation package includes:

• Articles of Organization filing with Colorado Secretary of State
• One year of registered agent service in Colorado
• Custom Operating Agreement
• EIN application
• Banking introduction letter
• Digital document delivery within 24 hours of state approval
• Compliance calendar with all filing deadlines
• Dedicated support via email and WhatsApp
