How to Form an LLC in Colorado (2026)
Reviewed by DocDraft Legal Team · Colorado · Last updated 2026-08-06
A limited liability company (LLC) is a business structure that legally separates the company from the people who own it, so the owners are generally not personally responsible for the company's debts. Forming one in Colorado means filing a formation document with a state agency and paying its fee to bring the company into legal existence. In Colorado you create an LLC by filing the Articles of Organization online with the Secretary of State and paying a $50 filing fee. Two features make Colorado easier and cheaper than most states. First, Colorado charges no franchise tax or minimum annual tax on LLCs, so there is no recurring state tax simply for existing. Second, Colorado accepts formation only online, and online filings are typically processed immediately, so the LLC can exist the same day. The ongoing state obligation is a $25 Periodic Report filed each year with the Secretary of State. Colorado LLCs are governed by the Colorado Limited Liability Company Act in Title 7, Article 80 of the Colorado Revised Statutes. This guide explains what an LLC is, the exact Colorado steps and fees, and the deadlines that keep the company in good standing.

How do you form an LLC in Colorado?
File the Articles of Organization online with the Colorado Secretary of State and pay the $50 filing fee. Colorado accepts LLC formation only through its online system, and filings are typically processed immediately. You must name a registered agent with a Colorado street address who can accept legal documents for the company.
How much does it cost to form an LLC in Colorado?
The Colorado Secretary of State charges a $50 fee to file the Articles of Organization, paid once when you form the LLC. After that, the main recurring state cost is the $25 Periodic Report filed each year. Colorado charges no franchise tax or minimum annual tax on LLCs.
Does Colorado have an LLC franchise tax?
No. Colorado does not impose a franchise tax or a minimum annual tax on LLCs, so there is no recurring state charge simply for the company to exist. This differs from states like California and Delaware. Colorado LLCs still file federal taxes and a $25 Periodic Report with the Secretary of State each year.
Does Colorado require newspaper publication to form an LLC?
No. Colorado does not require an LLC to publish notice of its formation in a newspaper. This is unlike New York, Arizona, and Nebraska, where publication is a condition of forming or operating. In Colorado the online Articles of Organization filing and the annual Periodic Report are handled entirely through the Secretary of State.
Colorado LLC formation at a glance
You form a Colorado LLC by filing the Articles of Organization with the Secretary of State for a $50 filing fee, submitted online through the Secretary of State's website at coloradosos.gov. What sets Colorado apart is how light the ongoing burden is. Colorado charges no franchise tax and no minimum annual tax on LLCs, so unlike California or Delaware there is no recurring state tax just to keep the company alive. Colorado also accepts formation only online, and online filings are typically processed immediately, so a Colorado LLC can exist the same day it is filed. The one continuing state obligation is a Periodic Report filed with the Secretary of State each year for a $25 fee, which keeps the company's address, registered agent, and status current. Every Colorado LLC must name and maintain a registered agent with a physical Colorado street address. Colorado does not require newspaper publication. The governing statute is the Colorado Limited Liability Company Act, Colorado Revised Statutes Title 7, Article 80, sections 7-80-101 and following.
Forming a two-owner Colorado LLC, step by step
Suppose two friends in Denver want to open a small design studio as an LLC. First they search the Colorado Secretary of State's business database to confirm their name is available and includes a designator such as LLC, and they can reserve the name with the Secretary of State for a $25 fee while they prepare paperwork. Next they appoint a registered agent: one owner lives in Colorado and agrees to serve, using a Colorado street address, not a P.O. box, where legal papers can be delivered during business hours. They then file the Articles of Organization online with the Secretary of State and pay the $50 filing fee. Because Colorado processes online filings immediately, the LLC legally exists the same day. Because they have two members, they also write an operating agreement setting each owner's percentage and how profits split, even though Colorado does not require them to file it. They apply to the IRS for a free EIN so the partnership can file taxes and open a bank account. Finally they calendar the $25 Periodic Report, which the Secretary of State expects each year to keep the company in good standing. Colorado charges them no franchise tax or minimum annual tax, so beyond the annual report their recurring state cost is limited.
Relevant Laws
Colorado Limited Liability Company Act (C.R.S. Title 7, Art. 80, §§ 7-80-101 et seq.)
The Colorado LLC Act governs the formation, management, and dissolution of every Colorado LLC. It sets who may form an LLC, the required contents of the Articles of Organization, and the default rules for member-managed and manager-managed companies. It works alongside the general provisions in Article 90 that cover registered agents and periodic reports for Colorado entities.
C.R.S. § 7-80-204 (Articles of Organization)
Requires a Colorado LLC to be formed by delivering Articles of Organization to the Secretary of State for filing. The articles state the LLC's name, its principal office address, its registered agent and that agent's Colorado address, and whether the company is managed by members or managers. In Colorado the articles are filed online, and the filing fee is $50.
C.R.S. § 7-90-701 (Registered agent required)
Requires every Colorado LLC to continuously maintain a registered agent in Colorado. The agent, an individual who resides in Colorado or a business authorized to act as agent, receives lawsuits and official notices for the company. The agent must have a physical Colorado street address, which is listed in the Articles of Organization and updated in the Periodic Report.
C.R.S. § 7-90-501 (Periodic report)
Requires a Colorado LLC to deliver a Periodic Report to the Secretary of State each year to keep the company in good standing. The report confirms the LLC's principal office address and registered agent. The Secretary of State sets the fee by rule, and the current Periodic Report filing fee is $25. Missing the report can move the LLC to noncompliant status.
No Colorado franchise or minimum annual tax on LLCs
Colorado does not impose a franchise tax or a minimum annual tax on LLCs. Unlike California's $800 minimum tax or Delaware's $400 annual tax, a Colorado LLC owes no recurring state tax simply for existing. A Colorado LLC still reports income for federal tax and pays Colorado income tax on income sourced to the state, and members report pass-through income on their own returns.
IRS federal tax classification (default pass-through)
The IRS does not tax the LLC as a separate category. By default a single-member Colorado LLC is disregarded and taxed like a sole proprietorship, and a multi-member LLC is taxed as a partnership, with income passing through to the owners. An LLC may instead elect S corporation or C corporation treatment. This federal classification is separate from Colorado's own income tax rules.
Regional Variances
How forming an LLC in Colorado differs from other states
No franchise tax or minimum annual tax
This is the headline difference. Colorado imposes no franchise tax and no minimum annual tax on LLCs, so a Colorado LLC owes no recurring state charge simply for existing. Compare California, where every LLC owes at least $800 a year, or Delaware, where the annual tax is $400. Over the life of the company this makes Colorado one of the cheaper states to keep an LLC in good standing.
Online-only filing, processed immediately
Colorado accepts LLC formation only through the Secretary of State's online system, with no paper option, and online filings are typically processed immediately. Many states still process mailed filings that can take days or weeks. In Colorado the LLC generally exists the same day you file the Articles of Organization.
Low $50 filing fee
Colorado charges $50 to file the Articles of Organization. That is well below states like Texas at $300 or Massachusetts at $500, and it keeps the cost of forming a Colorado LLC among the lowest in the country.
Annual Periodic Report, not a biennial report
Colorado requires a Periodic Report each year for a $25 fee. Some states use a biennial cadence instead, and a few charge much higher report fees. The annual Colorado report is modest, but forgetting it moves the LLC to noncompliant status, so the deadline still matters.
No newspaper publication requirement
Colorado does not require you to publish notice of formation in a newspaper. New York, Arizona, and Nebraska do, which adds cost and a deadline. A Colorado LLC is complete once the Secretary of State files the Articles of Organization, with no publication step.
Suggested Compliance Checklist
Confirm your LLC name is available and compliant
Before filing days after startingSearch the Colorado Secretary of State's business database to confirm your desired name is not already in use and that it includes a required designator such as LLC or Limited Liability Company.

Decide whether you, a co-owner who lives in Colorado, or a commercial registered agent service will serve. You will name the agent in the Articles of Organization, so settle this first.
File the Articles of Organization online with the Secretary of State
To create the LLC days after startingFile the Articles of Organization through the Colorado Secretary of State's online system at coloradosos.gov and pay the $50 filing fee.

Adopt an operating agreement
At or soon after formation days after startingPut the ownership percentages, profit split, management structure, and exit rules in writing. Colorado does not require you to file an operating agreement, but it governs how the LLC runs and overrides the Colorado LLC Act's default rules.

Frequently Asked Questions
An LLC, or limited liability company, is a business structure that separates the company from its owners as a matter of law. The owners, called members, are generally not personally liable for the company's debts or lawsuits, so a creditor usually cannot reach a member's home or personal savings for a business obligation. Colorado LLCs are created under the Colorado Limited Liability Company Act in Title 7, Article 80 of the Colorado Revised Statutes. An LLC pairs that liability protection with pass-through taxation and lighter paperwork than a corporation.
A sole proprietorship is not a separate legal entity, so the owner is personally on the hook for every business debt and lawsuit. A Colorado LLC exists once you file the Articles of Organization with the Secretary of State and pay the $50 fee, and that filing creates the liability shield between your business and your personal assets. A sole proprietor files nothing with the state and pays no formation fee, but also gets no protection. Attorney review of your setup is available through DocDraft if you want a second look.
Colorado uses an annual Periodic Report rather than a biennial one. You file it with the Secretary of State each year for a $25 fee, and the state assigns your filing window based on the month you formed the LLC, then emails a reminder when it opens. The report simply confirms your principal office address and registered agent. Missing the window moves the company to noncompliant status, so calendar it when you form. There is no separate franchise or minimum annual tax on top of this.
Colorado requires every LLC to continuously maintain a registered agent with a physical Colorado street address, not a P.O. box, available during business hours to accept lawsuits and official state mail. The agent can be you, a co-owner who resides in Colorado, or a commercial registered agent service authorized to act in the state. You name the agent in the Articles of Organization and keep the details current through the annual Periodic Report. If the agent lapses, the state can flag the company.
Yes. If you are not ready to file the Articles of Organization yet, Colorado lets you reserve an available name with the Secretary of State for a $25 fee, which holds it while you prepare your paperwork. Before reserving, search the Secretary of State's business database to confirm the name is not already taken and that it includes a designator such as LLC or Limited Liability Company. Reserving is optional; many filers skip it and simply file online when the name clears.
Usually the same day. Colorado accepts LLC formation only through the Secretary of State's online system at coloradosos.gov, with no paper option, and online filings are typically processed immediately. Your LLC legally exists the moment the Secretary of State files your Articles of Organization, so keep the filed confirmation as proof. This is faster than states that still process mailed forms over days or weeks. You can then get a free EIN from the IRS and open a business bank account.
