Business Corporation Formation Filing Requirements in Colorado

At a glance

Requirements one by one

Colorado uses a filer affirmation instead of a signature block

Under § 7-102-101, one or more persons may act as incorporators, and an individual incorporator must be at least 18. Under § 7-90-301, no signature or execution is required for a document filed under the general filing rules. Instead, § 7-90-301.5 makes the individual who causes delivery affirm under penalty of perjury that the filing is authorized, true, and compliant.

The filing publicly identifies at least one such individual and mailing address, along with every incorporator and mailing address. The incorporator does not have to be an owner, director, or officer.

The articles combine offices, agent, shares, and a cumulative-voting choice

Under § 7-90-601, the name must contain corporation, incorporated, company, limited, or one of the listed abbreviations.

Under § 7-102-102, the articles state the corporate name, share information, initial agent name and address, initial principal-office address, and every incorporator's true name and mailing address. The current checklist adds the principal and agent mailing addresses and confirms that the principal street address and filing-individual information are public.

Under § 7-106-101, the articles state every class and its authorized count. Multiple classes require their designations, preferences, limitations, and relative rights, and the classes collectively must carry unlimited voting rights and net-asset rights on dissolution. Par value is optional.

Under § 7-102-102(2)-(3), the articles may also add initial directors, purpose, management and power terms, par value, stated shareholder liability, and the qualifying liability and business-opportunity provisions described in the act. Colorado also makes cumulative voting the default: the articles must say so if cumulative voting is not desired; silence preserves it.

Agent consent is retained, not attached

Under § 7-90-701, the corporation maintains a qualifying Colorado registered agent, and the appointment statement confirms the agent consented. The current checklist says written consent to use a person's name or address is kept in the filer's own records and does not accompany the filing.

Effective August 12, 2026, chapter 226 also prohibits using a fraudulent entity as registered agent.

Online filing costs $50 and payment completion matters

The current Secretary of State forms page sends an ordinary profit corporation to online filing, and the fee schedule lists $50 online with no paper option. Under § 7-90-304, the filing takes effect at filing unless it states a later effective time or date, capped at 90 days. Under § 7-102-103, corporate existence begins on that filing or delayed date.

Chapter 226 adds a payment trap. If the electronic payment is not successfully processed or is reversed, the document was not successfully filed despite its initial timestamp. The Secretary of State may mark it void and adjust entity status or remove it from the online system.

Organization depends on whether the articles elect directors

Under § 7-102-105, incorporators may adopt initial bylaws and elect directors when the articles do not elect them. The initial directors then may adopt bylaws, appoint officers, and handle other business. Under § 7-102-106, initial bylaws may come from the board, incorporators before directors are elected, or shareholders if neither acted.

Under § 7-108-202, the board may act by unanimous written consent unless the bylaws require a meeting. The same consent method is available for incorporator organizational action.

What trips people up

Silence on cumulative voting is not an opt-out. Colorado's articles must state that cumulative voting is not desired; otherwise it is mandatory for director elections, subject to the cited statutory provisions.

Payment is part of successful filing. Since August 12, 2026, a reversed or unprocessed electronic payment means the document was not successfully filed, even if it initially received a time or date stamp.

Common questions

Must Colorado articles be signed?

No. Section 7-90-301 removes the signature requirement. The individual causing delivery instead supplies identifying information and makes the statutory perjury affirmation.

Must the articles name initial directors or officers?

No. Initial directors are optional, and officers are appointed during organization. If the articles do not elect directors, the incorporators handle the first organizational step.

Is there an immediate report or newspaper publication?

No. The first periodic report is not due until the statutory window following the first anniversary month. The current fee schedule lists a $25 periodic report fee.
