How to Start an LLC in Colorado

An LLC (aka Limited Liability Company) is a hybrid business entity combining a corporation’s characteristics with a partnership or sole proprietorship. It separates your personal assets from your business assets, thus giving you personal asset protection. For an LLC, members’ personal assets are not affected by business debts. However, in some cases, if the LLC is sued for business debts, courts might pierce the corporate veil and use the owner’s personal assets to meet their corporate liabilities.

If you wish to start an LLC, you must file your Articles of Organization with the State and pay a filing fee of $50. While it’s the most important step, it’s not the only one. There are 4 other crucial steps to follow to get your LLC formed in Colorado. Below are all 5 steps that explain everything you need to do to start a Colorado LLC in 2024. Let’s get started! You can always hire a professional LLC formation service in Colorado to set up your LLC instead of doing it alone; a Pro service will ensure everything is done properly.

Step 1: Decide a Name for Your Colorado LLC

Colorado name your llc

The first step while forming a limited liability company in Colorado is to give a proper name to your LLC. Before you name your business, you must know that the name should be easy to remember, available in the state, and follows all the LLC naming guidelines.

LLC Naming Guidelines in Colorado

There are a few specific requirements all the LLCs in Colorado have to follow while naming their Company. Some of the most important requirements are as follows:

  • Your business name should be available and no other existing business in Colorado can have the same name. ZenBusiness offers unlimited business name searches without any hassle.
  • “Limited Liability Company”, “LLC”, “L.L.C.”, “LC”, “L.C.”, and “Limited Company” – any one of these has to be used as a suffix in your business name.
  • You cannot use any name for your business that is confusing or misleading. Terms such as “Treasury”, “State Department”, “FBI”, “CIA”, etc. shouldn’t be included.
  • Terms like “Bank“, “University“, “Attorney“, “Doctor“, etc can be added only after the additional requirements by Colorado State Government are fulfilled.
  • (Optional) It’s better to name your business something for which your desired domain is available.

Reserve Business Name for Future

If you do not wish to file your LLC right now but want to hold the name you have decided, then you can reserve your LLC name for 120 days. To keep the name, you must file a name reservation application and pay $25 to the Colorado Secretary of State. You can renew your LLC name for another 120 days. For more, read Colorado LLC Name Search.

Doing Business As (DBA) or Trade Name

Once you have a legal name for your LLC, you can register it. However, it is not mandatory. You can, instead, use DBA, Fictitious Name, or Trade Name (in Colorado). In that case, you must register your name with the Colorado Secretary of State by submitting Trade Name Online Form along with the filing fee of $20.

Recommended: You can do name search, business domain, website, emails, and a lot more in one place by hiring a professional service. We recommend using –


ZenBusiness($0 for LLC Formation)

Apart from LLC formation, ZenBusiness offers customized website templates and business emails at a very reasonable price. If you plan to get a website, then it is wise to have a “.com” domain for your business, but these days you can also use other TLDs like “.io”, “.company”, “.xyz,” etc. Here you can get everything you need for your business in one dashboard.

Do I have to include LLC in my company email/domain?

It is not legally mandatory to use the word LLC in your domain name or email. If you want, you can use it. However, it is recommended not to use LLC in the domain name. A domain name should be short and easy to remember.

Step 2: Assign a Registered Agent in Colorado

colorado registered agent

The second step to forming an LLC in Colorado is to appoint a Registered Agent. A registered agent is a person or business entity working on your LLC’s behalf. This person or business will receive important tax forms, legal documents, all notices of lawsuits, and other official government correspondence in Colorado. Hence, hiring a competent Colorado Registered Agent for your LLC is necessary.

Make sure your registered agent is a resident of Colorado or has a physical street address. This address will be used as the principal address of your LLC to receive any legal documents. Most LLC formation companies also provide registered agent services. Below are two great LLC formation services; even if you buy their cheapest plan (normally $0), you also get registered agent service and other services at a very reasonable price.

This standalone service might become handy if you are doing it yourself and don’t want to disclose your home address or you don’t want to pierce the corporate veil.

Who Can Be a Registered Agent?

A person above 18 years of age and has a physical address in the state of Colorado can be a Registered Agent. A Registered Agent can be an independent person or can be a business entity. One is responsible for handling all the legal documents on the LLCs behalf.

Can I Be My Own Registered Agent?

Yes, you can be your own registered agent if you are a resident of the state of Colorado and you are above 18 years of age. To become a registered agent, you must have the authority to conduct any type of business in Colorado.

Why Shouldn’t I be My Own Registered Agent?

There are a few reasons why you shouldn’t be your own registered agent. The address of the registered agent is used to communicate with the SOS or for any legal activities. If you are your own registered agent, you might have to upload your personal address to the public forum. Besides, the registered agent must be at the address during business hours. It won’t be easy for you as you also have to take care of other things in your LLC. Hence, it is wiser to appoint a separate entity as your registered agent.

What is Piercing the Corporate Veil in LLC?

If an LLC is sued in Colorado, in some cases, courts might decide to lift the corporate veil, which means the owners of the LLC will be personally liable for their business debts. They might have to forgo their personal assets to repay their business debts. This is called piercing the corporate veil, where personal and business assets are not separated anymore. Your personal assets can be protected if you have enough capital and all your LLC documents are properly filed.

Registered Agent Consent Application

In Colorado, the registered agent has to sign a consent letter (online or offline) confirming consent to being Appointeded in written or electronic form. This consent must include the following details,

  • LLC name
  • A letter that says the person gives a consent to serve the LLC as a registered agent
  • The execution date
  • Name of the registered agent
  • Signature of the registered agent

This consent letter assures that the Registered Agent has given his nod to serve as an Agent. This part comes with the Registered Agent registration form. Later, if an LLC needs to change the Registered Agent, then they can submit the consent alongside. It comes on the registered agent change form. The Acceptance of Consent (online) can be filed by paying a filing fee of $10. For more information on the same, read our guide on Colorado Registered Agent.

Step 3: File Articles of Organization in Colorado

This document is vital as it ensures that all business owners are on the same page regarding how they operate, thus reducing future conflicts.

After Starting Your LLC

After forming your LLC, there are still some things that you will need. The most important thing is to separate your business and personal assets. LLCs have limited liability protection that protects your personal assets from business liability. This is called a corporate veil. However, the corporate veil can be lifted or pierced by the court if the LLC is sued. In that case, the owners of the LLC become personally liable for their corporate debts. A few things like appointing a legit registered agent, having enough capital, and filing all the major documents with the state can save the LLCs from being pierced into the corporate veil.

BOI Report Filing

According to the Corporate Transparency Act, every LLC, corporation, and other type of business that is registered with the Colorado SOS or similar authority, must file the BOI report with FinCEN. From January 1, 2024, it is mandatory to file a BOI report for every business entity. In this report, LLCs have to share information about the beneficial owners (having equal or more than 25% share). LLC owners can file BOI reports online or offline.

LLCs in Colorado that are created before January 1, 2024, should file their BOI report by January 1, 2025. LLCs that are created in 2024, must file the BOI report within 90 business days of finishing the LLC formation process. Missing out on filing the BOI report may lead to a monetary penalty of $500/day.

Things to Consider While Starting an LLC in the State of Colorado

This article has all the broad steps to form an LLC. However, these are only the basic steps. There are some more things you need when you start an LLC in any of the states. This step-by-step guide will help you to understand things in detail.

An LLC is a simple business structure. It does not take much effort to form your LLC. However, even if it is a simple business structure, you need to get a few things. For example, you need business accounts. It is good to separate your personal and business bank accounts. Get a business credit card to ease your business.

For an LLC, the tax burdens are much less. Other than usual income taxes, no major business taxes are required to pay for an LLC. LLCs with employees are required to pay employment taxes. If you hire employees in your LLC, then you need to obtain EIN. Members of an LLC do not have to pay federal income taxes based on their revenue from LLC. They only have to pay income taxes based on their personal income. Other taxes, like some federal taxes, self-employment taxes, and sales taxes, are required to pay.

Another thing about hiring a registered agent is the agent has to be available at the principal office address during business hours. They will receive all types of business documents and physical documents at the mailing address.

A single-member LLC is similar to a sole proprietorship. At the same time, a multi-member LLC is similar to a traditional corporation. Hence, the tax liabilities are similar to these structures. LLCs get to choose the tax structure at the time of registration. Based on that, it gets taxed.

It is wiser to have a professional service provider. With them, you will get various services, such as amendment filing service, business license report service, name reservation service, faster filing service, registered agent for service of process, and other formation services. The type of service may vary with the service plans you choose.
