Colorado LLC Operating Agreement Guide (2026)
Colorado does not legally require an LLC to have an operating agreement, and you never file one with the state - only the $50 Articles of Organization is public. But under the Colorado Limited Liability Company Act (C.R.S. § 7-80-108), the operating agreement is the controlling contract among the members, overriding most of the statute's default rules. Every Colorado LLC, including a single-member one, should have a written agreement.

Does Colorado Require an Operating Agreement?
No. Nothing in the Colorado Limited Liability Company Act (Title 7, Article 80 of the Colorado Revised Statutes) forces an LLC to adopt an operating agreement, and the Colorado Secretary of State never asks for one. When you form a Colorado LLC, the only document you file is the Articles of Organization, submitted online for a $50 fee. The operating agreement is a separate, private contract you create yourself.
"Not required" is not the same as "not important." Colorado's statute expressly contemplates an operating agreement and gives it broad legal effect, so the practical answer for almost every owner is that you should have one. Without it, you are silently agreeing to every default rule the legislature wrote - some of which will not fit your business. See what an LLC is and the national operating agreement overview for the concept across states.
What an Operating Agreement Does
An operating agreement is the internal rulebook of your LLC. It records who owns the company, how much each member contributed, how profits and losses are split, who manages day-to-day operations, how big decisions get made, what happens when a member wants out, and how the company can be dissolved. In a multi-member LLC it is the primary tool for preventing and resolving disputes; in a single-member LLC it is the primary tool for proving the business is a genuine separate entity.
The agreement also matters to outsiders. Banks frequently require it to open a business account, lenders and investors review it during due diligence, and courts look to it when deciding whether members respected the LLC's separateness - a key factor in preserving limited liability and avoiding "piercing the veil." Because it is a contract, it can be tailored far beyond what the Articles of Organization capture.
Colorado's Statutory Default Rules
When an operating agreement is silent, or does not exist, the gaps are filled by the default provisions of the Colorado LLC Act. These defaults are functional but generic. For example, absent a different agreement, Colorado law addresses how members vote, how distributions are shared, how a member's interest may be transferred, and when and how the LLC winds up and dissolves.
A common surprise is profit sharing. Many owners assume profits automatically follow ownership percentages, but the statutory default and your intended deal can diverge, especially where members contributed unequal amounts of cash versus labor. Another is voting: the default may give each member an equal say or tie voting to contributions in a way the members did not expect. A custom operating agreement lets you set these terms deliberately instead of inheriting them. For related governance questions, see single-member LLC and LLC vs corporation.
Member-Managed vs. Manager-Managed
Colorado LLCs are member-managed by default, meaning the owners run the business directly. The Articles of Organization state whether the LLC is member-managed or manager-managed, and the operating agreement then spells out what that structure means in practice: who has authority to sign contracts, spend money, hire, and bind the company.
In a manager-managed LLC, the members appoint one or more managers (who may or may not be members) to run operations, while the members keep authority over major decisions such as admitting new members, amending the agreement, selling the business, or dissolving. This structure suits passive investors or larger ownership groups. Your operating agreement should define manager powers, how managers are chosen and removed, term length, and which decisions still require a member vote. This should match the management choice recorded in your Articles of Organization.
Single-Member vs. Multi-Member Agreements
A single-member operating agreement is shorter but still valuable. Its main jobs are to document that the LLC is separate from its owner, to name who takes over if the owner dies or becomes incapacitated, and to satisfy banks and other third parties. Because there is only one owner, the profit-sharing and voting sections are simple, but the separateness and succession language does real work in protecting limited liability.
A multi-member agreement is where careful drafting pays off. It should cover capital contributions and whether members can be required to contribute more later, how profits and losses are allocated, how and when distributions are made, voting thresholds for ordinary versus major decisions, transfer restrictions and rights of first refusal, and a buy-sell mechanism for death, disability, divorce, or a member wanting to exit. Getting these terms in writing up front prevents most partnership disputes.
What to Include in a Colorado Operating Agreement
While there is no state-mandated form, a thorough Colorado operating agreement generally covers the items below. Tailor them to your ownership structure rather than copying a generic template.
| Section | What it settles |
|---|---|
| Company basics | LLC name, principal office, registered agent, purpose, term |
| Members & ownership | Each member's name, capital contribution, and ownership percentage |
| Management | Member-managed or manager-managed; authority and duties |
| Voting | What needs a vote and the threshold (majority, supermajority, unanimous) |
| Profits & distributions | How profit and loss are allocated and when cash is distributed |
| Transfers | Restrictions on selling an interest; rights of first refusal |
| Buy-sell / exit | What happens on death, disability, withdrawal, or deadlock |
| Dissolution | Events that trigger wind-up and how assets are distributed |
| Amendments | How the agreement itself can be changed |
Keep the signed agreement with your company records alongside your EIN confirmation and your recorded Articles of Organization. If you later change members, management, or ownership percentages, amend the agreement to match. See how to get an EIN for the federal number your agreement should reference.
Nonwaivable Provisions Under Colorado Law
Colorado's LLC Act is mostly a menu of default rules the members can rewrite, but not everything is up for grabs. Under C.R.S. § 7-80-108, an operating agreement generally may not eliminate the duty of loyalty or the obligation of good faith and fair dealing, though it may identify specific categories of activity that do not violate those duties if not manifestly unreasonable. It also may not unreasonably restrict a member's right to inspect the LLC's records, and it cannot override the rights of third parties who are not part of the agreement.
These guardrails matter because they set the outer limit of what your customization can achieve. Within them, you have wide latitude - Colorado gives strong effect to the deal the members actually struck. If you are drafting aggressive provisions (for example, waiving fiduciary-type duties or heavily restricting exit), that is exactly where professional review is worth the cost. For a definitional refresher on the terms used here, see the glossary.
How to Adopt and Amend the Agreement
To put an operating agreement in place, the members agree on the terms, reduce them to writing, and sign. There is no notarization or state filing requirement in Colorado; the members' signatures make it binding. For a single-member LLC, the sole member simply signs. Date the agreement and give each member a copy.
Amend the agreement whenever the underlying facts change - a new member joins, ownership percentages shift, you switch from member-managed to manager-managed, or you change how profits are split. Follow the amendment procedure in the agreement itself (often a majority or unanimous vote). Because none of this is filed with the state, keeping your internal records current is entirely your responsibility. When you eventually close the business, your agreement's dissolution terms guide the process described in how to dissolve an LLC in Colorado.
Frequently Asked Questions
Is an operating agreement required for a Colorado LLC?
No. Colorado does not require one and you never file it with the Secretary of State. But the Colorado LLC Act treats the operating agreement as the controlling contract among members, so having a written one is strongly recommended. See the national operating agreement guide.
Do I file my Colorado operating agreement with the state?
No. It is an internal document you keep with your records. The only formation filing is the Articles of Organization, which costs $50 online. Details are on how to form an LLC in Colorado.
Does a single-member Colorado LLC need an operating agreement?
Not legally, but it is worth having. It documents that the LLC is separate from its owner (helping preserve limited liability), and banks and lenders often ask to see it.
What happens if a Colorado LLC has no operating agreement?
The default rules in Title 7, Article 80 of the Colorado Revised Statutes govern voting, profit sharing, management, and dissolution. Those defaults may not match the owners' intent, which is the main reason to write your own.
Can a Colorado operating agreement override state law?
Mostly. The LLC Act is largely default rules you can change. But under C.R.S. § 7-80-108 certain items are nonwaivable - you generally cannot eliminate the duty of loyalty, the obligation of good faith, or a member's reasonable right to inspect records.
