Corporation Registered-Agent Change and Resignation Requirements in Colorado

At a glance

Requirements one by one

Colorado uses an agent address rather than a separate registered office

The Colorado Business Corporation Act works with the common entity rules in Title 7, Article 90. Colo. Rev. Stat. § 7-90-701 requires the corporation to continuously maintain one registered agent in Colorado. The record uses that person's registered-agent address; it does not create a separate registered- office field that must match some other office.

Under § 7-90-102(56), the physical location is the individual agent's Colorado residence or usual place of business, or the entity agent's Colorado usual place of business. A usual place must be customarily open during normal business hours with an authorized individual commonly present to accept process and notices. A different Colorado mailing address is optional, but a U.S. or commercial post-office box cannot be the physical street location.

Eligibility now includes identity or residency verification

An individual must be at least 18 and have a Colorado primary residence or usual place of business. The individual also needs a current Colorado driver license or ID card, or must complete the Secretary's alternative residency-verification process. Current SOS instructions use a passcode route when the state credential cannot be verified.

A domestic entity agent must be in good standing and have a usual place of business in Colorado. A foreign entity must also be authorized to transact business or conduct activities in the state. A qualifying corporation may serve as its own agent, but the SOS treats self-service at formation as a two-step process: appoint another eligible agent first, then appoint the newly formed, good-standing corporation itself through a change filing.

Since August 12, 2026, 2026 Colo. Sess. Laws ch. 226 (HB 26-1088) also prohibits using an entity determined to be fraudulent as a registered agent. That rule is current, not merely pending.

The filing identifies the change and the individual causing delivery

Colo. Rev. Stat. §§ 7-90-304 and -305.5 govern the statement's contents and effective time, while § 7-90-702 permits the corporation to change the agent, agent name, or address through that statement, a periodic report, or another prescribed filing. The online statement pre-fills the entity ID and name, then collects the changed agent name or address, the required consent affirmation, any applicable entity-notice affirmation, an optional delayed date, and the causing individual's name and mailing address.

Colo. Rev. Stat. §§ 7-90-301 and -301.5 do not require a signature as a filing condition. Instead, causing delivery is the individual's perjury affirmation that the record is that individual's act or is in good faith believed to be the act of the represented person, its facts are believed true, and it complies with the filing law, constituent documents, and organic statutes. The surveyed provisions state no additional board- or shareholder-vote prerequisite. Chapter 226 separately prohibits delivery without necessary written consent or authority.

Agent-initiated, correction, and mass-change routes stay separate

When the agent's own name or address changes, Colo. Rev. Stat. § 7-90-702(2) requires a statement reciting that the agent delivered notice to the entity. If the recorded name or address was wrong when the earlier document was filed, § 7-90-703 uses a correction instead; a person listed without consent may also file a correction after notifying the entity.

Colorado's current mass-change procedure is administrative rather than a commercial-agent listing. The SOS accepts a mass request only for at least 550 records. The current form charges $50 at application plus approximately $1.80 per record before application of the change, and warns the full process may take two to three months. The official 2025 printout still places its commercial- registered-agent language behind a certification-triggered future version that the editor's note says had not taken effect, and current SOS filing materials continue to use the ordinary individual-or-entity model.

Resignation ends on day 31 unless another date arrives first

Under Colo. Rev. Stat. § 7-90-702(4), the agent—or a listed legal representative when the agent is deceased or under a guardian or conservator—files the recorded agent name and address, the date the agent resigned or otherwise ceased serving, and an affirmation that notice was delivered to the entity.

The filing becomes effective on day 31 after filing, a stated delayed date from day 31 through day 90, or the earlier effective appointment of a successor. Current SOS status guidance says an entity becomes Noncompliant if no successor is appointed within 30 days after the current agent's resignation; 60 uncured days in Noncompliant status then produce Delinquent status.

Online change, resignation, and correction filings each cost $10

An ordinary change takes effect when filed unless a valid delayed time or date is stated under Colo. Rev. Stat. § 7-90-304. A delayed date may extend no later than day 90; date-only filings take effect at 11:59 p.m. Current SOS guidance says successful online filings process in real time and immediately update the record, unless delayed. 2026 Colo. Sess. Laws ch. 226 (HB 26-1088) now makes unsuccessful or reversed payment mean the document was not successfully filed despite any initial timestamp.

The current fee schedule charges $10 each for an agent change, agent resignation, agent-information correction, or no-consent correction. The periodic-report route costs $25. These particular filings are online-only on the schedule, so the separate $150 paper expedited-service line does not provide an expedited version of the online agent change.

Service and delinquency continue after the agent disappears

Colo. Rev. Stat. § 7-90-704 authorizes service on the agent. When there is no agent, the agent is not found under the recorded name at the recorded address, or reasonable diligence cannot serve the agent, registered or certified return- receipt mail may go to the corporation's principal address. Service is perfected at the earliest of receipt, the signed-return date, or five days after mailing. The section does not make that the only possible service method.

Failure to comply with Part 7 is a delinquency ground under Colo. Rev. Stat. §§ 7-90-901 to -902. After the Secretary determines the ground, the corporation has 60 days to correct it or demonstrate that it does not exist before becoming delinquent. Delinquency pauses the corporation's ability to maintain a Colorado court proceeding to collect its debts, but it does not terminate corporate existence or the agent's authority. After three uncured years, a manager may use the separate § 7-90-908 dissolution filing; dissolution is not automatic when the agent first disappears.

What trips people up

• The registered-agent street address is not merely a mailing destination. It must be a qualifying Colorado physical location that is actually staffed in the statutory normal-hours sense.
• Resignation effectiveness, Noncompliant status, and Delinquent status are separate events. Day 31 ends the appointment under the ordinary statute; agency status then follows its own replacement and cure sequence.
• A successful-looking timestamp is not enough if payment fails or is reversed. Chapter 226 now says the document was not successfully filed.
• The mass-change program is not a fast bulk portal: it begins at 550 records and the agency warns of a two-to-three-month process.

Common questions

May the corporation appoint itself as agent?

Yes, if it is in good standing and has a qualifying Colorado usual place of business. Current SOS instructions require another eligible agent at formation and a later change filing to appoint the newly formed corporation itself.

May agent information be changed in the periodic report?

Yes. Section 7-90-702 expressly allows that route, and § 7-90-501 requires the report to contain current agent name and address information. The current periodic-report fee is $25, compared with $10 for the stand-alone change.

What if someone was named without consenting?

Section 7-90-703 permits that person to file a statement of correction stating that the person is not the agent and that notice of the correction was delivered to the entity. The current online fee is $10.
