Best Registered Agent Services for Colorado LLCs (2026)
Affiliate disclosure: Northwest Registered Agent, Bizee, ZenBusiness and LegalZoom pay us a commission if you sign up through our link, at no extra cost to you. We list only the registered agent services we have an affiliate relationship with, so this is not a survey of the whole market.
This table is not scored. The four are listed cheapest annual renewal first, and the rows below it say which one fits which situation. The scored ranking, and the formula behind it, is on the formation services review, which orders them on three-year cost, BBB rating and Trustpilot score.
Note: Bizee holds a C rating from the BBB and is not accredited. BBB's profile carries a live alert describing a pattern of complaints about unexpected charges, difficulty canceling and filing delays, and Bizee has posted a response to it. We flag this so you can make an informed choice.
Prices are each provider's standard published rates; year-one pricing applies when you form your LLC through the same service. BBB and Trustpilot figures as recorded September 15, 2026, not re-checked since, and both sources update continuously. These are the dates the figures were last written to our dataset, which is the most we can show: they are not verification dates.

Which Registered Agent Is Best for Your Colorado LLC?
You're forming a new LLC and want the agent bundled
Our pick: ZenBusiness
Registered agent is free for year one with their $0 starter formation plan, backed by an A from the BBB and a 4.8/5 Trustpilot score.
Your LLC already exists and you just need an agent
Our pick: Northwest Registered Agent
A flat $125/yr for registered agent service, the lowest renewal of the services listed here, and a privacy policy that says it does not sell your information. Registered agent customers are enrolled by default in annual report filing at $100 plus state fees, which you can cancel.
You want year one free and the cheaper renewal after it
Our pick: Bizee
Registered agent is free for year one on every Bizee plan and renews at $149/yr, $50/yr less than ZenBusiness, the other service listed here that includes year one free. Northwest renews lower still at $125/yr, but its first year comes inside a paid $39 formation package rather than free. Tradeoff: a C rating from the BBB, which cites a pattern of complaints about charges and cancellation, so read every auto-renewal term.
Complex legal needs alongside your filing
Our pick: LegalZoom
The only one of the services listed here with licensed attorney consultations, and the most expensive registered agent listed here at $249/yr, which is never included in their plans.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state publishes about filing deadlines, fees, and the consequences of missing them, with the sources this page cites. It cannot tell you what your own company owes: the date turns on when and where you formed, states change these rules between our reviews, and in several states an entity-level tax falls due in a year when no report does. Confirm your own dates with the filing office named on this page before you rely on one here, because the penalty for missing a deadline can be administrative dissolution of the company.
Frequently Asked Questions
A registered agent is a person or business designated to receive legal documents, tax notices, and official correspondence on behalf of your Colorado LLC. Colorado Revised Statutes § 7-90-701 requires every LLC to maintain a registered agent with a physical street address (not a P.O. box) within Colorado at all times. This agent serves as your company's official point of contact for the Colorado Secretary of State, which uses this address to deliver dissolution notices, statutory demands, and litigation documents. Without a registered agent, you risk missing critical deadlines, such as the Periodic Report, which is keyed to your LLC's anniversary month and can be filed two months before or two months after that month without penalty. Missing it can lead to administrative dissolution of your LLC and personal liability exposure. Many Colorado LLC owners use professional registered agent services like Northwest or Registered Agent Inc., which cost $100 to $300 annually, rather than designating themselves and exposing their home addresses on public filings. Your next step is to designate a registered agent before filing your Articles of Organization with the Colorado Secretary of State or update your current agent immediately if it's missing.
Operating without a registered agent violates Colorado Revised Statutes § 7-90-701 and exposes your LLC to serious consequences. The Colorado Secretary of State can administratively dissolve your LLC without notice if you fail to maintain a registered agent, effectively shutting down your business operations. Beyond dissolution, you risk missing critical legal documents, lawsuits, tax notices, and regulatory correspondence sent to your registered agent address will go unserved, potentially resulting in default judgments against your company. The state may also assess penalties and revoke your LLC's good standing status, preventing you from renewing licenses, opening business bank accounts, or conducting transactions in Colorado. This cascading liability creates personal exposure if courts determine you operated illegally. To protect your LLC immediately, file Form LLC-1 with the Colorado Secretary of State listing a registered agent (either yourself at a Colorado street address or a professional service) and pay the standard filing fee. Verify this agent maintains a physical office in Colorado and will reliably receive documents during business hours.
In Colorado, serving as your own registered agent is completely free, but hiring a professional registered agent service typically costs $100 to $300 annually. The Colorado Secretary of State doesn't charge a separate fee for registered agent designation on your Articles of Organization form (Form 102). However, if you use a professional service, reputable Colorado-based providers like Northwest Registered Agent or LegalZoom usually charge $150 to $200 per year for basic service, with additional fees for expedited document handling or mail forwarding. Many online incorporation services, including some Colorado-specific providers, bundle the first year of registered agent service into their incorporation packages at no extra cost. This matters because choosing the wrong option can expose your business to missed legal deadlines, if your registered agent doesn't properly receive and forward service documents, you could face default judgments. To move forward, compare quotes from at least three Colorado registered agent providers, or decide whether you've a physical Colorado office to reliably receive legal documents before committing to self-service.
Your registered agent's name and address appear on all official documents filed with the Colorado Secretary of State's Division of Corporations, making this information publicly accessible through their online database. If you use a professional registered agent service, your personal home address remains completely private. Only the agent's business address appears in public filings. However, if you serve as your own registered agent, your personal residential address becomes permanently part of the public record and searchable by competitors, creditors, and the general public. This distinction matters significantly for Colorado LLC owners who value privacy or operate from home, as your address will be visible on your Articles of Organization and annual reports filed with the state. To maintain privacy while meeting Colorado's mandatory registered agent requirement, hiring a professional service is the most practical solution. Most charge between $100 to $300 annually. Contact the Colorado Secretary of State's Division of Corporations at (303) 894-2200 to verify your current registered agent information, or research professional registered agent providers licensed to serve Colorado entities.
Yes, you can change your registered agent in Colorado at any time by filing a Statement of Change of Registered Agent with the Colorado Secretary of State's Business Division. The current filing fee is $25, payable online through the Secretary of State's website. To avoid losing legal notification coverage, you must have your new registered agent in place and ready to accept service before you officially remove the old one, any gap in coverage could cause you to miss critical legal documents or court notices. Both your current and incoming registered agents must consent to the change in writing. File your completed form through the Colorado Secretary of State's online portal or by mail to their Denver office. Processing typically takes 3 to 5 business days. Once approved, your new agent's address becomes your official service of process location, so verify they're prepared to receive documents before submitting the change request.
