Colorado Articles of Organization: Cost & Filing (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

You form a Colorado LLC by filing the Articles of Organization online with the Colorado Secretary of State and paying a $50 filing fee. Colorado accepts online filings only, so there is no paper form and approval is usually immediate. You must name a Colorado registered agent on the Articles, and each year you file a $25 Periodic Report to keep the LLC in good standing.

What the Colorado Articles of Organization Do

The Articles of Organization is the founding document that legally creates a Colorado limited liability company. Filing it - and the Colorado Secretary of State's acceptance of it - is the legal act that brings the LLC into existence under the Colorado Limited Liability Company Act, part of Title 7 of the Colorado Revised Statutes. Until the Articles are recorded, the entity does not exist and its owners have no liability shield.

Colorado is unusual: unlike most states, it does not offer a paper form. Every business document, including the Articles of Organization, is filed through the Secretary of State's online business portal. People sometimes call this document a "certificate of formation" or "certificate of organization," but Colorado's actual document for an LLC is the Articles of Organization - see Colorado "Certificate of Formation" explained. If you are researching the general process first, see how to form an LLC and the primer on what an LLC is. For the full state walk-through, see how to form an LLC in Colorado.

What the Colorado Articles Require

The Articles of Organization are short. Under C.R.S. § 7-80-204, the online form asks for a limited set of items:

LLC name. The name must contain an LLC designator (such as "LLC," "L.L.C.," "Limited Liability Company," or a permitted abbreviation) and be distinguishable on the records of the Secretary of State from existing names.
Principal office address. The street and mailing address of the LLC's principal office.
Registered agent and registered agent address. A Colorado street address; a P.O. box alone does not satisfy the requirement.
Management structure. Whether the LLC is member-managed or manager-managed.
Person forming the LLC. The name and address of at least one person forming the company, and a statement that the individual causing the delivery of the document is authorized to do so.

Because the form is standardized, most rejections come from a name that is not distinguishable or a missing registered-agent address rather than the body of the document. Your internal governance - ownership percentages, voting, and profit distribution - goes in an operating agreement, which Colorado does not file.

How to File the Colorado Articles of Organization

Because Colorado is online-only, filing is quick once your name and registered agent are ready. The steps are:

Choose and check your LLC name. Search the Secretary of State business database to confirm the name is available and distinguishable. If you are not ready to file, you can reserve a name for 120 days by filing a Statement of Reservation of Name for $25. Confirm the name does not infringe a federal trademark.
Appoint a Colorado registered agent. Line up a registered agent with a physical Colorado street address who consents to serve - yourself, a manager, or a commercial service.
Complete the Articles of Organization online. Open the form in the Secretary of State's portal and enter the name, principal office, registered agent, management structure, and organizer.
Pay the $50 fee and submit. Colorado processes online filings immediately, so once you pay and submit, the Secretary of State records the filing and your LLC legally exists - generally the same day.
Get an EIN and register for Colorado taxes. Apply for a free federal EIN from the IRS, then register with the Colorado Department of Revenue for a sales tax license or a wage-withholding account if your activity requires it.
File your annual Periodic Report. Each year, file a Periodic Report for $25 during your anniversary-month filing window.

After these steps, open a business bank account - banks generally ask for the recorded Articles of Organization and the EIN - and keep your registered agent and Periodic Report current.

Colorado LLC Filing Fees (2026)

The core cost of a Colorado LLC is the $50 Articles of Organization fee. The table below lists the state fees most new LLCs encounter, each drawn from the Colorado Secretary of State fee schedule or the Colorado Department of Revenue. Amounts are set by the state, not by any filing service.

Item	Filing	Fee (2026)	Agency
Create the LLC	Articles of Organization	$50	Secretary of State
Annual report	Periodic Report	$25	Secretary of State
Reserve a name (120 days)	Statement of Reservation of Name	$25	Secretary of State
Change registered agent	Statement of Change	$10	Secretary of State
Trade name (DBA)	Statement of Trade Name	$20	Secretary of State
Sales tax license (2-year)	Form CR 0100	$16 + $50 deposit	Department of Revenue
Federal EIN	IRS Form SS-4	$0 (free)	IRS

Colorado's formation fee is among the lowest in the country, and there are no per-member charges. Colorado has periodically offered temporary reduced business-filing fees, so confirm the current amount on the Secretary of State fee schedule before you file. For a full year-one and ongoing breakdown, see Colorado LLC cost and the national cost of an LLC.

Colorado Registered Agent Requirement

A Colorado registered agent is the person or entity your LLC designates to receive service of process, tax notices, and official state correspondence. The Colorado Corporations and Associations Act requires every domestic entity, including an LLC, to continuously maintain a registered agent with a Colorado address, and you name the initial agent directly in the Articles of Organization under C.R.S. § 7-90-701.

The agent must be either an individual who is at least 18 years old and whose primary residence is in Colorado, or a business entity that has a usual place of business in Colorado and is authorized to transact business there. A post office box alone does not satisfy the requirement; a physical street address is required, and the named agent must have consented to serve. To change agents later, file a Statement of Change for $10. See Colorado registered agent requirements and the national registered agent overview for detail.

The Periodic Report (Colorado's Annual Report)

Colorado calls its annual filing a Periodic Report, not an annual report. Every LLC must file one each year with the Secretary of State to keep its status in good standing under C.R.S. § 7-90-501. The fee is $25, effective since July 1, 2024 (it was previously $10). The report simply confirms your entity name, principal office, and registered agent; there is no financial disclosure.

The Periodic Report is due in your LLC's anniversary month, and the Secretary of State opens a filing window that spans the month before, the anniversary month, and the two months after. If you miss the window, your LLC becomes noncompliant and then delinquent, and you must file a Statement Curing Delinquency and pay the current cure fee to return to good standing. Full timing and penalty detail is on our Colorado Periodic Report page.

After Filing: EIN, Taxes, and Sales Tax License

A federal Employer Identification Number (EIN) is issued free by the IRS and is used to open a bank account, hire employees, and file taxes. By default, the IRS treats a single-member LLC as a disregarded entity and a multi-member LLC as a partnership under Treasury Regulation 26 CFR 301.7701-3; either can elect corporate or S-corporation treatment by filing the appropriate IRS form. An EIN is required if the LLC has more than one member or any employees.

Colorado imposes a flat 4.40% individual income tax, so LLC income that passes through to members is taxed at that single rate. If your LLC sells taxable goods or certain services, you must obtain a Colorado sales tax license from the Department of Revenue using Form CR 0100; the standard retail license costs $16 for a two-year period plus a refundable $50 deposit. Colorado has no general statewide business license, but many cities and counties require their own. See business license in Colorado and the national business license guide.

Common Mistakes and Rejections

Most Articles of Organization problems are avoidable. The frequent ones are: choosing a name that is not distinguishable from an existing Colorado entity; entering a P.O. box instead of a physical street address for the registered agent; naming an agent who has not consented; and forgetting to calendar the annual Periodic Report, which quietly pushes the LLC into delinquency. Because Colorado filings are online and immediate, an error is recorded instantly, so review each field before you submit. Filing accurately the first time preserves your intended formation date and avoids a curative filing later.

Closing a Colorado LLC

When you decide to close the business, do not simply stop filing the Periodic Report - that leads to delinquency rather than a clean close. Instead, wind up the LLC's affairs, settle debts and taxes, and file Articles of Dissolution online with the Secretary of State. See how to dissolve an LLC in Colorado and the national dissolution overview for the full wind-up and filing steps.
