How to Form an LLC in Colorado

There are several steps every business owner should take when setting up an LLC in Colorado.

Keep in mind that professional advice is always best when setting up any business, especially for those new to this process or without experience with it.

1. Choose the Type of Your Colorado LLC (Mandatory)

When choosing the type of LLC for your business in Colorado, it’s crucial to weigh the advantages and disadvantages of each structure:

  • Single-Member LLC: Ideal for solo entrepreneurs, this structure offers simplicity in management and tax filing. However, it may have limited growth potential and less credibility with banks and investors compared to multi-member LLCs.
  • Multi-Member LLC: Suitable for businesses with multiple owners, providing shared responsibility and potentially more resources for growth. The downside includes potential internal conflicts and more complex decision-making processes.
  • Series LLC: This is beneficial for those managing multiple, distinct asset groups or projects under one umbrella, as it isolates liabilities. However, its complexity in setup and management, along with varying recognition in other states, can be challenging.

I advise my clients that each type offers distinct benefits and challenges, so it's important to select the one that aligns best with your business goals and operational style.

2. Choose a Name for Your LLC (Mandatory)

Choosing the right business name is a critical step in forming an LLC. I remember the process of naming the first LLC for my client; it was both exciting and challenging.

The name needs to be unique, capturing the essence of the business while adhering to specific requirements, including length constraints.

Your business name must also end with an 'LLC' abbreviation for Limited Liability Company, 'LLC,' 'LLC Ltd, or 'LC.' This will ensure legal protection and allow you to obtain the necessary business licenses required for your business registration in Colorado.

You can find the detailed requirements for an LLC name and name availability at the Colorado Secretary of State (SOS) [1].

If the LLC name is available, file the Statement of Reservation of Name. The reservation will allow you to reserve a business name for 120 days while you finalize the business formation documents. The LLC name reservation filing fee is $25.

3. Select a Registered Agent (Mandatory)

Colorado law requires that any individual or business entity must hire a registered agent service to accept important legal documents on its behalf and provide legal advice when needed.

Your registered agent should: 

  • Operate within the state
  • Have a registered office
  • Be available at their street address to sign for these notices during regular business hours

LLC's registered agent services in Colorado start around $50 a year, but this cost can go up depending on the company structure and the individual needs of your business.

Additionally, in most cases, filing your LLC without a registered agent or using just an address service (PO Box) that forwards mail to you is impossible.

4. File Articles of Organization (Mandatory)

The next step is to file the LLC Articles of Organization to start an LLC in Colorado.

Articles of Organization represent a document that formally creates the company in Colorado. Any business owner, member, or manager must file it with the Colorado Secretary of State.

Once this procedure is completed, you'll receive official Articles of Organization forms.

This document provides essential information about your business, including its:

  • Name
  • Address
  • Registered Agent information
  • Company structure
  • Purpose
  • Members/managers
  • LLC's street address on record as the principal office location

The Articles of Organization for your LLC can only be filed online through the Colorado Secretary of State website. To file Articles of Organization, you need to pay a $50 filing fee.

Steps to Take After Forming an LLC in Colorado

Reading important files

An LLC operating agreement in Colorado is a legal document that contains specifications about the rights, duties, and responsibilities of LLC members.

The operating agreement also defines procedures for resolving issues within the company, managing major financial decisions, or changing membership status.

Operating agreements are not required by Colorado business law, but they're highly recommended because:

  • It's a great way to ensure all business owners have a clear understanding of their roles and how the business works;
  • Operating agreements can help hold you accountable as a manager or member since breaking the rules set out in your operating agreement may be grounds for expulsion from the LLC;
  • They create legally binding contracts between each owner/manager, which protects all parties involved. If an issue arises where it needs to go before a judge, the LLCs operating agreement offers a clear interpretation of how the company should operate.

You can draft your operating agreement yourself or seek assistance from an attorney to ensure it aligns with Colorado state laws and meets your business needs.

I assisted a client who was struggling with vendor relationships. They didn't realize that many suppliers and vendors prefer or require an EIN to process transactions.

Once they obtained their EIN, it streamlined their procurement process and opening a business bank account.

A tax ID number is created to be used for tax filing purposes and can be obtained by applying through an online form with the IRS [2]. The procedure usually takes no more than 15 minutes and is free of charge.

Employer Identification Number helps you to maintain a corporate veil and protect your personal assets from tax liabilities and other legal claims.

Once you have successfully registered your LLC, opening a business bank account is important.

"A business bank account draws a clear line between personal and business finances, a separation crucial for legal and tax considerations, as well as future financing endeavors."

- Delina Yasmeh, J.D./Tax LL.M, Distinguished Expert in Mergers & Acquisitions

To open a business bank account for your LLC, you must provide your LLC formation documents, EIN, and identification documents.

Research different banks and their account options to find the one that best suits your business.

Once you have chosen a bank, schedule an appointment or visit their website to begin the account opening process.

8. File Your Colorado LLC Annual Report (Mandatory)

I advise my clients to prioritize the annual report, an essential requirement for maintaining the legal status of your LLC in Colorado.

Each year, you need to submit this report to the Colorado Secretary of State. It typically includes key details like your LLC's principal office address, and the names and addresses of managers or members.

The process is predominantly done online, through the Colorado Secretary of State's website. The state imposes a filing fee, generally around $10, making it one of the more affordable aspects of maintaining an LLC.

The due date for this report is set around the anniversary of your LLC’s formation date each year. Neglecting to file by the deadline can lead to penalties, and in severe cases, dissolution of your LLC.

9. Obtain Business Licenses and Permits

Holding paper requirements

Business license requirements for an LLC could be obtained on the federal, state, and local levels, although you might not be required to have them all.

To check the federal license requirements, make sure to visit the U.S. Small Business Administration website and obtain information about business licenses [3].

State licenses are mandatory for LLCs to be able to start sales and pay taxes.

Businesses that supply services, manufacture products, or sell items might also need a sales tax license from state agencies. You can inquire about state licenses by contacting Colorado's Department of Regulatory Agencies [4].

You should also contact the State Licensing Board if your LLC plans to provide professional services, such as dentistry, architecture, engineering, etc. In these instances, all or some members of the else need to be licensed.

If you plan on starting your LLC in a certain town/city in Colorado, make sure they have general business license requirements before moving forward with the establishment process.

10. Choosing Your Tax Structure

A limited liability company is considered a "pass-through" entity, meaning your company's profits are passed directly onto you and taxed as ordinary income.

Determining whether LLC is the right business structure for your business involves understanding the state tax requirements. LLCs need to pay federal taxes and continue collecting sales tax.

This is beneficial compared to setting up an S-Corp or C-Corp if you want to avoid being taxed double (where the business pays taxes on its earnings, and so do you).

A single-member LLC is taxed not as a separate entity, but through the individual's personal federal return using Schedule C, mirroring the tax treatment of a sole proprietorship.

An LLC that chooses to be taxed as a corporation needs to file Form 2553 with Internal Revenue Service [5]. In this case, the LLC files a separate tax return. You can download this form from the IRS website. The corporate income tax rate in Colorado is 4.63% [6].

Drawing from experience, many small businesses in Colorado prefer pass-through taxation for its simplicity and individual tax benefits.

To change your tax structure, file the appropriate form with the IRS, ideally before the tax year begins. For S corp status, the deadline is usually by March 15th of the current tax year. This flexibility allows Colorado LLCs to adapt their tax approach as their business evolves.

Benefits and Drawbacks of an LLC in Colorado


  • Limited Liability Protection: LLC members are protected from personal liability for business debts, a fundamental advantage of this structure.
  • Flexibility in Taxation: Colorado LLCs can choose how they are taxed (pass-through, S corp, or C corp), offering flexibility to optimize tax obligations.
  • Ease of Formation and Maintenance: Colorado's LLC formation process is streamlined and cost-effective, with simple annual requirements and low fees. This approach is especially beneficial in a state where 99.5% of businesses are small enterprises (684,726 in total, according to 2023 US Small Business Administration statistics), aiding their growth and reducing bureaucratic obstacles [7].
  • No State Income Tax on LLC Profits: Colorado does not levy a state income tax on LLC profits that pass through to members' personal tax returns, which can be a significant financial benefit.


  • Self-Employment Tax: Earnings of LLC members are subject to self-employment taxes in Colorado, which can be higher than corporate tax rates.
  • Limited Growth Potential: For some businesses, the LLC structure may limit potential growth opportunities, such as raising capital through stock sales.
  • Franchise Tax: While Colorado's tax structure is generally favorable, LLCs may be subject to a franchise tax, depending on their revenue and structure.

DIY vs. Professional LLC Formation

DIY LLC Formation


  • Cost-Effective: DIY is generally less expensive since you are not paying for professional services.
  • Full Control: You have complete control over the formation process and document preparation.


  • Time-Consuming: It requires significant time to understand and complete all the necessary steps and paperwork.
  • Legal Complexities: Without legal expertise, you might miss critical legal requirements or make errors in documentation.
  • No Compliance Assistance: You're responsible for ensuring ongoing compliance with state regulations, which can be complex.

Professional LLC Formation


  • Expertise: Professionals are knowledgeable about the legal aspects of LLC formation and can navigate complex requirements.
  • Time-Saving: They handle the paperwork and procedures, saving you time and effort.
  • Compliance Assistance: Many services offer ongoing support for maintaining compliance with state laws.
  • Peace of Mind: Professional assistance can provide confidence that your LLC is formed correctly.


  • Cost: Professional services are more expensive than the DIY approach.
  • Less Control: You may have less involvement in the formation process.
