There are many benefits of starting a new venture in Colorful Colorado. It’s ranked in the top 10 best states to start a business, and eight of the Fortune 500 companies call Colorado home. What does that mean for you? A business-friendly environment with the resources to support entrepreneurs.

This comprehensive guide walks you through Colorado's specific requirements, procedures, and ongoing compliance obligations for incorporating your business in the Centennial State.

Form a Corporation

What is a corporation, and why incorporate in Colorado?

A corporation is a legal entity separate from its owners (also called shareholders) that can conduct business, enter contracts, own property, and be held liable for its actions. In Colorado, corporations are governed by Title 7, Article 90, of the Colorado Revised Statutes.

Benefits of incorporating in Colorado

Colorado offers several advantages for business incorporation:

  • Limited liability protection. Shareholders are not personally responsible for the corporation's debts and financial obligations, protecting personal assets from business liabilities.
  • Tax advantages. Colorado corporations benefit from the state's relatively business-friendly tax environment, including a flat 4.4% corporate income tax rate as of 2024.
  • Credibility and permanence. A corporate structure enhances business credibility with customers, vendors, and financial institutions while providing continuity beyond the involvement of any individual owner.
  • Access to capital. Corporations can raise funds through the sale of stock and have easier access to business loans and investment opportunities.
  • Colorado-specific benefits. The state offers streamlined online filing processes, reasonable filing fees, and efficient processing times through the Colorado Secretary of State's office.

Benefits of incorporating in Colorado vs. forming an LLC

While both corporations and limited liability companies (LLCs) provide limited liability protection, they differ significantly in structure and taxation:

  • Taxation. Colorado corporations face double taxation (corporate and individual shareholder levels), while LLCs typically enjoy pass-through taxation. However, corporations can elect S corporation status to avoid double taxation. (LLCs can also elect S corporation designation if it makes sense for their business.)
  • Management structure. Corporations require a formal structure, with directors, officers, and shareholders, while LLCs offer more flexible management arrangements.
  • Growth and investment. Corporations are better suited for raising capital through stock sales and attracting investors, while LLCs are ideal for smaller, closely held businesses.
  • Compliance requirements. Colorado corporations must maintain more corporate formalities, while LLCs have fewer ongoing requirements.

How do I incorporate in Colorado?

The Colorado Secretary of State provides a streamlined process for forming corporations. Here's the step-by-step procedure.

Step 1: Choose and reserve your corporate name

Before filing, verify your desired corporate name is available through the Colorado Secretary of State's Name Availability Search database. In addition to being distinguishable from other business entity names registered or reserved in the state, your corporation name will fulfill the naming regulations:

  • Must contain the words "corporation," "incorporated," "company," or "limited," or the abbreviations "corp.," "inc.," "co.," or "ltd."
  • Should typically avoid terms that are associated with government agencies or use words like “bank” or “trust” unless authorized to do so

If you’re not ready to file but you want to secure your corporate name, file a Statement of Reservation of Name online through the Colorado Secretary of State’s website. Name reservations cost $25 and last 120 days.

Step 2: Designate a Colorado registered agent

Every Colorado corporation must maintain a registered agent with a Colorado address. The registered agent receives official correspondence, legal documents, and notices on behalf of the corporation. The registered agent can be one of three things:

  • An individual who is at least 18 years old with a primary residence or business address in Colorado
  • A business entity formed or authorized to do business in Colorado with a usual place of business in Colorado
  • The corporation itself, if it has a Colorado address

You’ll need to obtain consent from your designated registered agent to be able to list them on your articles of incorporation.

Step 3: Prepare and file your articles of incorporation

To form a corporation in Colorado, you’ll need to submit articles of incorporation online through the Colorado Secretary of State's website. Articles of incorporation must include the following information:

  • Corporate name
  • Address of the corporation's principal office and mailing address
  • Registered agent name, Colorado address (not a P.O. box), and consent
  • Stock structure, including total number of authorized shares and classes; the distinguishing designation for each class (if there are multiple classes); and relative rights, limitations, and preferences of each class of shares
  • Names and addresses of incorporators
  • Incorporator’s signature (signers must be at least 18 years old)

Once all the information is filled out, pay the $50 filing fee through credit, debit, or a prepaid account (no cash or checks are accepted).

Step 4: Create corporate bylaws (optional, but recommended)

While Colorado doesn't require corporations to adopt bylaws, they are highly recommended. Corporate bylaws should establish routine regulations and procedures that your corporation may need:

  • The number of directors and their selection process
  • Officer roles and responsibilities
  • Shareholder meeting procedures
  • Voting requirements and procedures
  • Stock transfer restrictions
  • Amendment procedures

LegalZoom can assist with creating corporate bylaws for your business.

Step 5: Appoint directors and officers

Colorado corporations are required to have a board of directors consisting of one or more directors (the exact number should be specified in your corporate bylaws). Directors are then elected at each annual meeting. 

Once the board of directors is created, then officers can be appointed, such as president, secretary, and treasurer. One person can hold more than one office. Officer duties should be laid out in the corporate bylaws.

Step 6: Get a federal employee identification number (EIN)

All corporations are required by the IRS to get an EIN, which is essentially a tax ID number. You can apply for one through the IRS’ website or get one with LegalZoom’s EIN service.

How much does it cost to incorporate in Colorado, and how long does it take?

The Colorado Secretary of State charges $50 to process your articles of incorporation, but if you want to reserve your name before you’re ready to officially incorporate, you can reserve it for 120 days for $25. 

Online filings with the Secretary of State are processed in real time, so once you pay the filing fee, your articles of incorporation will likely be processed immediately. Once it’s approved, you can request certified copies online for free. 

What filings are required after incorporation in Colorado?

Periodic reports and due dates

Colorado corporations must file periodic reports (also called annual reports in other states). Your periodic report is due within two months of the anniversary of your incorporation (e.g., if incorporated in March, the report is due by May 31st). It costs $25 to file, and it must include the following information: 

  • Business name and ID number
  • Business email address
  • Current registered agent name and address
  • Principal office address
  • Name and address of person filing the report

If you do not file on time, your corporation will incur a $50 late fee. Failure to file results in delinquency and potentially a loss of good standing with the state or administrative dissolution.

Amendments and changes

When corporate information changes, you must file amendments or corrections, such as the following, with the Colorado Secretary of State:

  • Articles of incorporation amendments are required for changes to corporate name, authorized shares, or other charter provisions. You can file online through your business record with the Secretary of State for a $25 filing fee.
  • A Statement of Change of Registered Agent is required when changing registered agents. This has a $10 filing fee.
  • A Statement of Correction is used to correct errors in previously filed documents. This could cost up to $10, depending on what information is being corrected.
  • A Voluntary Dissolution Form is used if you would like to close your corporation and costs $10.

FAQs about Colorado corporations

How many shares should I authorize?

Colorado doesn't limit the number of authorized shares, and there's no additional fee based on share quantity. It may be best to speak with an attorney or tax professional regarding how many shares to authorize.

Can I form a corporation by myself?

Yes, Colorado allows single-person corporations. You can serve as the sole incorporator, director, officer, and shareholder. However, you still need a registered agent with a Colorado address.

Do I need bylaws?

While Colorado doesn't require bylaws, they're highly recommended. Bylaws establish internal governance rules such as meeting procedures and officer duties. They're especially important for corporations with multiple shareholders.

What is a registered agent, and can I be my own?

A registered agent receives legal documents and official correspondence for your corporation. You can serve as your own registered agent if you have a Colorado address, are available during business hours, and meet the other state requirements. However, many businesses hire professional registered agent services, such as LegalZoom’s registered agent services, for privacy and reliability.

How do I elect S corporation status?

To elect S corporation status, first ensure that your business meets the IRS’ requirements for S corporations. Then, file Form 2553 with the IRS. Colorado automatically recognizes federal S corporation elections, so no separate state filing is required.

How do I change my corporation's name or address?

To change your corporation’s name or address, you must file an amendment to your articles of incorporation along with the $25 filing fee.

Can a trust or another entity own shares in a Colorado corporation?

Yes, Colorado law allows trusts, LLCs, other corporations, and various entities to own corporate shares. However, S corporations have restrictions on shareholder types that may affect eligibility.

Genaro was great!

Genaro was a great listener, remembered everything we spoke about and then walked me through the process of moving my LLC into a Corporation. Glad I called rather than try to do online - we got it all done in about 20 minutes.
