With low startup and formation costs, a highly educated population, and a business-friendly tax climate, Colorado consistently ranks as one of the best states to start a business. While Colorado also earns praise for its easy business formation process, you’ll still need to understand the steps involved—and one of the most important is to appoint a registered agent.
What is a Colorado registered agent?
A Colorado registered agent is a person or business entity designated to receive official legal documents and government correspondence on behalf of your business. Also known as a resident agent or statutory agent in some states, the registered agent serves as the state's primary point of contact for all important government and legal communications.
A Colorado registered agent's primary duties include:
- Receiving service of process for lawsuits, including employee litigation documents, garnishment proceedings, and other legal actions.
- Accepting official government correspondence from the Colorado Secretary of State, Department of Revenue, and other state agencies.
- Maintaining regular business hours (9 a.m. to 5 p.m., Monday through Friday) at a physical Colorado address.
- Ensuring timely delivery of all documents to business owners or designated representatives.
For example, if your Colorado LLC faces a lawsuit, the plaintiff's attorney will serve legal papers to your registered agent, who must then promptly forward these documents to you. This is why the job of a Colorado registered agent is so essential: If you don’t receive important documents, you could miss court dates and end up with a default judgment against your business.
Do I need a Colorado registered agent?
Every business entity registered with the Colorado Secretary of State must maintain a registered agent at all times. Businesses that are required to register include:
- Limited liability companies (LLCs)
- Corporations (C corporations and S corporations)
- Limited partnerships (LPs)
- Limited liability partnerships (LLPs)
- Foreign entities conducting business in Colorado
Businesses that do not need a registered agent in Colorado include sole proprietorships and general partnerships, because they are not required to register with the Secretary of State.
Colorado registered agent requirements (2025 update)
Effective July 1, 2025, Colorado amended C.R.S. § 7-90-701, enacting new requirements to combat fraud and improve compliance. Under the new law:
- Identification is required for individual registered agents to prove Colorado residency.
- Individual agents cannot use P.O. boxes or commercial mail services as their address.
- Entities serving as registered agents must have a usual place of business in Colorado, which does not include commercial or P.O. box addresses.
- Entities must register with the Colorado Secretary of State and maintain good standing with the state.
These new requirements apply to all new appointments and changes of registered agents and are in addition to the existing laws for individuals and entities.
Eligibility requirements for individuals
With the passage of the new law in 2025, the total requirements for individuals are as follows:
- They must be at least 18 years old.
- They must have a primary residence or usual place of business in Colorado that is open during normal business hours (no P.O. boxes or mail services are allowed).
- They must be present to accept service of process during normal business hours.
- They must hold a valid Colorado driver's license or state identification card, OR complete an alternative address verification process.
- They must provide written consent to serve as registered agent for the specific business entity.
If you or your registered agent doesn't have a Colorado state ID, you can request an agent passcode from the Colorado Secretary of State to verify Colorado residency. Here's how it works:
- Enter the agent’s name and physical street address to request a passcode during the online filing process.
- The Colorado Secretary of State will mail a passcode to your Colorado address.
- Enter the passcode online to complete the filing.
Note: Passcodes expire after 45 days, so complete the process promptly.
Eligibility requirements for business entities
With the new changes, a business entity can serve as a registered agent if they meet the following requirements:
- Is a domestic Colorado entity registered with the Colorado Secretary of State and in good standing, OR is a foreign entity registered to transact business in Colorado and in good standing
- Maintains a usual place of business with a physical street address in Colorado (P.O. boxes are not permitted)
- Has someone available during normal business hours to accept service of process
- Provides written consent to serve as registered agent
Can I be my own registered agent in Colorado?
Yes, you can serve as your own registered agent in Colorado if you are at least 18 years old, a Colorado resident with a physical street address, and are available to accept service of process during normal business hours. However, this decision comes with significant drawbacks that business owners should carefully consider.
Pros and cons of self-service vs. professional service
| Self-service | Professional service | |
|---|---|---|
| Cost | No ongoing fees | $100–$300+ annually |
| Privacy | Your address becomes public record | Service provider's address is public |
| Availability | Must be present during business hours | Professional availability guaranteed |
| Document handling | Personal responsibility for legal docs | Expert handling and forwarding |
| Compliance alerts | Self-managed deadlines | Automated reminders and alerts |
| Multi-state coverage | Limited to Colorado only | Available across multiple states |
| Business mobility | Tied to Colorado address | Flexibility to relocate |
A professional registered agent service is typically better if you:
- Work from home and want to keep your personal address private
- Travel frequently or work irregular hours
- Operate multiple business entities
- Plan to expand to other states
- Want other services, like document management and compliance reminders
How to appoint a Colorado registered agent
The process for appointing a Colorado registered agent varies depending on whether you're forming a new entity or updating an existing one.
During new LLC or corporation formation
If you’re forming a new business, you’ll appoint a registered agent when you file your articles of organization (for a Colorado LLC) or articles of incorporation (to form a corporation) with the Colorado Secretary of State:
- Go to the Colorado Secretary of State “File a Form” website.
- Choose the form you want to file.
- Complete the registered agent section, including the agent's full legal name, Colorado physical address, and written consent.
- Verify the agent's eligibility through Colorado ID or passcode process.
- Complete the rest of the information required on the form.
- Submit your formation documents through the online portal and pay the filing fee.
Note that paper or mail filing is not available for formation documents—you must file online. The filing fee for both LLCs and for-profit corporations is $50. There is no option for expedited service when filing online, because filings are typically already processed within three business days.
Foreign (out-of-state) entities
Foreign entities must appoint a Colorado registered agent when registering to do business in the state. The process is similar, but involves a different form than domestic entities. Regardless of your entity type, you will fill out a Statement of Foreign Entity Authority.
- Go to the Foreign Entity page on the Colorado Secretary of State filing website.
- Fill out the Application for Certificate of Authority, including designating a qualified Colorado registered agent.
- Include your agent consent and verification documentation.
- Submit the form and pay the $100 filing fee.
- Maintain the registered agent throughout your Colorado business operations.
How to change your Colorado registered agent
You can change your registered agent at any time after forming your business by filing a Statement of Change of Registered Agent with the Colorado Secretary of State:
- Go to the Record Search page to find the existing account you created when you formed your business.
- Select "Change Registered Agent" from the menu options.
- Complete the form, including your business information, new agent information, and the effective date of the change.
- Upload your identity verification and new agent consent documentation.
- Submit the form and pay the $10 filing fee.
If you only need to update your registered agent’s office address, use the Statement of Change Changing the Principal Office Address. There is also a separate form if your registered agent is resigning or being terminated, called the Statement of Change Regarding Resignation or Other Termination of Registered Agent.
If you hire LegalZoom as your registered agent, we’ll take care of the filing fee and paperwork at no additional cost to you.
After you file: Records and compliance
Once your change is approved, you’ll need to complete a few more steps to ensure you receive documents and your business is compliant.
- Update internal records to reflect the new registered agent.
- Notify relevant parties (banks, vendors, insurance companies) of the address change.
- Keep documentation of the change for your business records.
What happens if I don't have a registered agent in Colorado?
In Colorado, operating without a registered agent violates state law and exposes your business to several risks, including:
- Administrative dissolution of your business entity
- Inability to defend against lawsuits
- Loss of good standing with the Colorado Secretary of State
- Potential personal liability for business obligations
The new law passed in July 2025 also strengthens the state’s ability to enforce Colorado’s registered agent requirements:
- No grace period for fraud: If the state finds you appointed a registered agent without proper authorization or for fraudulent reasons, your business will be immediately marked delinquent. You will not have the usual 60-day grace period to fix it.
- Stricter filing rules: When you submit documents, you must confirm under penalty of perjury that you’re authorized and that everything is accurate.
Colorado registered agent cost
The minimum cost to appoint a Colorado registered agent for a new business is $50 to file your formation documents. The cost to change your registered agent is $10. Many businesses also choose to use a professional registered agent service, like LegalZoom, which can range from $100–$300 per year. With a service, you’ll get extra features like compliance reminders and access to your documents online.
Why use a professional Colorado registered agent
Professional registered agent services offer several advantages over self-service, especially if your business is growing or you have privacy and compliance concerns.
Privacy and address protection
Professional registered agents protect your personal privacy by using their business address as your registered address on public records. This means:
- Your home address stays private and off state databases.
- There is less risk of unwanted visitors or mail at your residence.
- You’ll have a professional business image with a commercial address.
For example, if you operate a home-based consulting LLC in Denver, using a professional registered agent prevents your residential address from appearing in Colorado Secretary of State records that are accessible to the public.
Availability and reliability
A reliable registered agent or registered agent service will provide the following:
- Consistent 9 a.m. to 5 p.m. availability Monday through Friday
- Trained staff familiar with legal document requirements
- Backup systems ensuring no missed service of process
- Professional handling of sensitive legal matters
Multi-state coverage for growing businesses
Most states have residency requirements for registered agents. This means that if you name yourself or an individual, like a friend or relative, you will only be able to act as a registered agent in the state of Colorado.
If your business operates in multiple states, professional services can make your life easier with consistent service standards across all 50 for seamless multi-state compliance. They also offer centralized document management, no matter how many locations your business has. And if you only have one location but are looking to grow, a professional service can simplify the expansion process when the time comes.
Extra services provided by professional registered agent services
Beyond basic registered agent duties, many professional services offer valuable additional features that can streamline your business operations and enhance compliance.
Reminders and document handling
Compliance is essential for your business to stay in good standing with the state of Colorado. Professional services often provide support such as:
- Automated deadline reminders for your Colorado periodic report (called an annual report in many states), tax filings, and other state requirements
- Expert document review to identify urgent legal matters requiring immediate attention
- Digital document scanning and secure online storage for easy access
- Proper forwarding procedures so you receive critical documents promptly
- Secure online portals for accessing documents from anywhere
Mail forwarding services
Colorado registered agents should always make sure you receive your documents in a timely manner. Depending on your service provider, a professional agent may also provide mail forwarding, which may include:
- Physical mail forwarding to your preferred address
- Selective forwarding of important documents only
- Package handling for small business-related deliveries
- Mail filtering to separate important documents from routine correspondence
Check with your registered agent service provider about their specific mail forwarding policies and any limitations on package size or frequency.
Formation and compliance services
Many businesses choose to use professional services not only for their registered agent, but also for other business needs. Registered agent providers are often companies that offer multiple services:
- Business formation, including filing articles of organization or articles of incorporation
- Ongoing compliance support for annual reports and state requirements
- Document preparation for business changes and updates
- Expert guidance on Colorado business law requirements
While professional registered agents are knowledgeable about Colorado's compliance framework, they are not attorneys and cannot provide legal or tax advice. For complex legal matters, consult with an experienced small business attorney.

Colorado registered agent FAQs
Can a registered agent use a P.O. box in Colorado?
No, Colorado law requires registered agents to maintain a physical street address. P.O. boxes, private mailbox numbers, and virtual addresses are not permitted for registered agent purposes.
Does a foreign entity need a Colorado registered agent?
Yes, any foreign (out-of-state) entity conducting business in Colorado must appoint a qualified Colorado registered agent when filing for a Certificate of Authority with the Colorado Secretary of State.
What address appears on the Colorado public record?
The registered agent's address appears on public records maintained by the Colorado Secretary of State. If you have a home-based or mobile business, this means your home address. This is why many business owners choose to use a service instead.
How do I change my registered agent in Colorado?
File a Statement of Change of Registered Agent (Form RGNT) with the Colorado Secretary of State, including the new agent's written consent and identity verification. The filing fee is $10 with 3–5 business day processing.
Can my registered agent resign?
Yes, but the resigning agent must give written notice to your business. You must then fill out the Statement of Change Regarding Resignation or Other Termination of Registered Agent with the Colorado Secretary of State, including confirmation that you received written notice. The change takes effect on the 31st day after you file the Statement of Change.
What is the difference between a registered agent and a registered office?
In Colorado, the registered agent is the person or entity, while the registered office is the physical address where the agent can be found during business hours. Both are required elements of your registered agent designation. However, you can change only the registered office of your agent without changing their name, for example if they move locations.
