Colorado LLC filing fee & timeline
To form an LLC in Colorado you file your Articles of Organization with the state and pay the state filing fee of $50. Incofile adds a flat, one-time service fee on top — no monthly charges — and your total is always shown before you pay.
Most Colorado LLC filings are prepared and submitted within one business day. State approval time depends on Colorado's current processing queue, typically ranging from a few business days to a few weeks, with expedited options available in many states.
Why form an LLC in Colorado
Colorado is quick and inexpensive: Articles are filed online only, cost $50 and are usually approved almost instantly. After that you file a $25 periodic report once a year. Owners pay Colorado's flat 4.4% income tax on their share of profit.

What you need to form an LLC in Colorado
- A business name that is available and meets Colorado's naming rules (it must include “LLC” or “Limited Liability Company”).
- A registered agent with a physical address in Colorado — Incofile can be your agent.
- Articles of Organization filed with the Colorado state office — we prepare and submit these for you.
- An operating agreement and EIN to open a business bank account (included in our Gold and Platinum packages).
- Ongoing compliance — Colorado's reports, taxes and registered agent rules (see below). We track the deadlines and remind you.
Operating agreement
An operating agreement sets out who owns the LLC, how profits are split, how decisions are made and what happens if a member leaves. Colorado does not ask you to file it with the state, but banks usually want to see it, and without one the state's default rules apply. Incofile includes a customised operating agreement in the Gold and Platinum packages.
EIN (Employer Identification Number)
Your EIN is the federal tax ID for your LLC. You need it to open a business bank account, hire staff and file taxes. The IRS issues it free — online in minutes if you have a Social Security number, or by fax or mail (one to eight weeks) if you don't. Our Gold and Platinum packages include it, and it is also available as a separate service.
This is general information, not legal advice. If you're unsure which structure is right, compare LLC vs S-Corp vs C-Corp.
Colorado LLC naming rules
The name must contain "limited liability company", "ltd. liability company", "limited liability co.", "ltd. liability co.", "limited", "l.l.c.", "llc" or "ltd." and must be distinguishable from every entity on the Colorado register. Check availability with our free business name search.
Keeping your Colorado LLC compliant
Periodic report
Every Colorado LLC files a periodic report each year. The window opens two months before your anniversary month and closes at the end of the second month after it. The fee is $25; filing after the window adds a $50 penalty and marks the LLC delinquent.
Registered agent
Colorado requires a registered agent with a physical Colorado street address. If you form from outside Colorado, a professional agent such as Incofile is the simplest option.
Taxes
Owners pay the flat 4.4% Colorado income tax on their share of profit. Colorado has home-rule cities that administer their own sales tax, so sellers may need both a state sales-tax licence and city licences.
Licences
There is no general state business licence. Many Colorado cities and counties require local licences, and regulated occupations are licensed by DORA.
Incofile clients get every Colorado deadline tracked in their dashboard with email reminders — see registered agent service.
