To form a Colorado corporation you file Articles of Incorporation with the Colorado Secretary of State for a $50 fee, and to keep it alive you file a $25 periodic report each year. Those are the two Colorado corporation filing requirements that matter most, but each one has rules around it, and missing either can push the entity into delinquency and eventual administrative dissolution.
What Must Be in the Articles of Incorporation
Colorado law requires five items in every set of Articles of Incorporation.1Justia. Colorado Code 7-102-102 – Articles of Incorporation
- An entity name that is distinguishable from every other name on file and that includes a corporate designator such as Corporation, Incorporated, Company, Limited, or an abbreviation like Corp., Inc., Co., or Ltd.2Justia. Colorado Code 7-90-601 – Entity Name
- The classes of shares the corporation can issue and the number of shares in each class. Multiple classes need distinguishing labels, and the rights and limitations of each class must be described before any shares in that class are issued.3Justia. Colorado Code 7-106-101 – Authorized Shares
- The name and Colorado street address of the initial registered agent.
- The principal office address where the corporation conducts its primary business.
- The true name and mailing address of every incorporator filing the document.
Colorado also lets you add optional provisions in the articles: naming the initial board, stating a specific business purpose, setting par value, limiting director liability, or providing for indemnification of officers and directors. None of these are required, but liability and indemnification language is worth deciding on at formation because amending the articles later costs another filing fee.
Registered Agent Rules
Every Colorado corporation has to maintain a registered agent at all times. The agent is the official recipient of lawsuits, government notices, and other legal documents on the corporation’s behalf.4Colorado Secretary of State. Registered Agent
An individual agent must be at least 18 and either live in Colorado or maintain a usual place of business in the state. An entity acting as agent must be in good standing with the Secretary of State and have a usual place of business in Colorado; foreign entities also need authorization to do business here.4Colorado Secretary of State. Registered Agent
The address on file has to be a physical street location, not a P.O. box or commercial mailbox, and it has to be staffed during normal business hours so documents can be accepted in person.4Colorado Secretary of State. Registered Agent Lose the agent without naming a replacement and the Secretary of State flags the corporation as noncompliant. A separate risk: an unserved lawsuit can produce a default judgment because no one was there to receive the complaint.
How to File and What It Costs
Colorado processes incorporation filings through the Secretary of State’s online portal. Paper filing exists for some entity types, but the standard route for a profit corporation is electronic. The system prompts you through the name, share structure, registered agent, principal office, and incorporator fields and gives you a review screen before submission.
The filing fee for a domestic profit corporation is $50.5Colorado Secretary of State. Business Organizations Fee Schedule Payment is by credit card or prepaid account. Once the system accepts the filing it issues a unique entity identification number, and the certificate of incorporation downloads immediately as a PDF. That certificate is the corporation’s proof of legal existence.
Online filings are typically processed on submission. Paper filings can be expedited for an additional $150, with fulfillment within three business days.5Colorado Secretary of State. Business Organizations Fee Schedule
What to Do After the State Accepts the Filing
The articles create the corporation. Several things still need to happen before it functions as a business.
Bylaws and the Organizational Meeting
Colorado law authorizes the board of directors, or the incorporators if no directors have been elected, to adopt initial bylaws. If neither acts, the shareholders can adopt them.6Justia. Colorado Code 7-102-106 – Bylaws Bylaws can cover anything related to managing the business, so long as nothing in them conflicts with Colorado law or the articles.
Initial directors usually hold an organizational meeting, called by a majority of the board, to adopt the bylaws, appoint officers, authorize a bank account, issue shares to the founding shareholders, and handle other startup items.7FindLaw. Colorado Code 7-102-105 – Organization of Corporation The meeting can be held anywhere, inside Colorado or not, and the same actions can be taken by written consent instead. Keep minutes. Corporate records are among the first things scrutinized if anyone later challenges whether the corporation was properly operated.
Employer Identification Number
The Colorado Secretary of State does not issue federal tax identification numbers.8Colorado Secretary of State. Starting a Business in Colorado You apply directly to the IRS. The online application issues the EIN immediately on completion. The EIN is required to open a business bank account, file tax returns, and hire employees.
S Corporation Election
A new corporation defaults to C corporation tax treatment, meaning the entity pays corporate income tax and shareholders pay again on dividends. To elect S corporation status so profits pass through to shareholders’ personal returns, file IRS Form 2553 within two months and 15 days of the beginning of the tax year the election is to take effect. For a brand-new corporation that generally means within two months and 15 days of the date the articles become effective. Every shareholder must sign the consent section; a single missing signature invalidates the election. The IRS does allow late elections with a reasonable-cause explanation, but relying on that leniency is a gamble.
Beneficial Ownership Information Reporting
The Corporate Transparency Act originally required most new corporations to file a Beneficial Ownership Information report with the Financial Crimes Enforcement Network. As of March 2025, FinCEN issued an interim final rule exempting all U.S.-formed entities from BOI reporting. Only entities formed under foreign law and registered to do business in a U.S. state must now file.9FinCEN. Beneficial Ownership Information Reporting A domestic Colorado corporation formed by U.S. persons currently has no BOI filing obligation. This area has changed more than once since 2024, so check FinCEN’s site before assuming the exemption still holds at the time you incorporate.
The Annual Periodic Report
Every Colorado corporation files a periodic report with the Secretary of State once a year.10Justia. Colorado Code 7-90-501 – Periodic Reports The report confirms or updates the entity name, principal office address, and registered agent information. If nothing has changed, you verify the existing data and pay the fee.
The deadline is tied to the anniversary of the corporation’s formation. The filing window opens two months before the periodic report month and closes two months after it, with the official due date falling on the last day of that second month after.11Colorado Secretary of State. Business FAQs – Periodic Reports A corporation formed in March, for example, has a window running from January through the last day of May. Filing anywhere in that five-month window avoids penalties.
The fee is $25 online. Missing the deadline adds a $50 late penalty on top of the report fee.5Colorado Secretary of State. Business Organizations Fee Schedule
What Happens When You Miss a Deadline
Colorado enforces compliance in three stages: noncompliant, delinquent, and dissolved. The costs climb at each one.
If the periodic report isn’t filed by its due date, the corporation’s status changes immediately to noncompliant.12Colorado Secretary of State. Noncompliance and Delinquency FAQs The same happens if the corporation stops maintaining a registered agent. The corporation still exists at this stage; it’s simply flagged in state records as out of compliance.
If the noncompliance isn’t cured within 60 days, the status escalates to delinquent.12Colorado Secretary of State. Noncompliance and Delinquency FAQs Reactivating a delinquent entity requires filing a Statement Curing Delinquency, which costs $100 on top of the overdue report fee and late penalty.5Colorado Secretary of State. Business Organizations Fee Schedule
If delinquency continues, the Secretary of State eventually dissolves the corporation administratively. A dissolved entity can no longer legally conduct business, and anyone who keeps operating under its name may face personal liability for obligations incurred after dissolution. Reinstatement requires Articles of Reinstatement for $100, and corporations dissolved for two years or longer must also submit additional documentation under penalty of perjury, including an affidavit and government-issued photo ID.13Colorado Secretary of State. Business FAQs – Reinstating a Business Any trade names the corporation held before dissolution are not automatically restored; new trade name statements have to be filed for each one.
A $25 report filed on time keeps the corporation in good standing. Letting it slide can easily add up to $175 or more in accumulated fees and penalties, with the added risk that any contract signed during the gap in good standing could leave the owners personally exposed.
