Colorado LLC Costs 2026: $50 to Form + $25/yr

Periodic Report Fee (Ongoing Cost)

Colorado LLCs must file a Periodic Report (Colorado's version of an annual report) each year. The filing fee is $25 — raised from $10 on July 1, 2024 — and the report is tied to your LLC's anniversary month, the month in which it was originally formed. This anniversary-based schedule means your filing window is unique to your LLC's formation date.

The Periodic Report updates your business information on file with the Colorado Secretary of State, including your principal office address, registered agent name and address, and the identity of your LLC's managers or members. Even if no information has changed since your last filing, you must still submit the report and pay the $25 fee to maintain your LLC's good standing.

Filing the Periodic Report online is simple and takes only a few minutes. The Secretary of State's portal pre-fills your existing information, so you only need to review it, make any updates, and submit payment. For a deeper walkthrough of the timing rules, see our guide to Colorado Periodic Report requirements.

If you miss the filing window, your LLC's status changes to Noncompliant and a $50 late filing penalty is added on top of the $25 report fee. If the report still isn't filed within roughly 60 more days, the status becomes Delinquent, which can affect your ability to enter contracts, obtain financing, or do business under the LLC's name. To return a delinquent LLC to good standing, you file a Statement Curing Delinquency for a $100 fee. An entity left delinquent for several years can ultimately be administratively dissolved.

Registered Agent Cost

Colorado requires every LLC to maintain a registered agent with a physical street address in Colorado. The registered agent receives legal documents, service of process, and official state correspondence on behalf of your LLC. If you hire a commercial registered agent service, typical pricing ranges from $100–$300 per year.

You can serve as your own registered agent in Colorado if you are a Colorado resident with a physical address in the state (P.O. boxes do not qualify). Acting as your own agent eliminates the recurring cost, but keep in mind that your personal address becomes part of the public record filed with the Secretary of State. Additionally, you must be available at that address during normal business hours to accept service of process, which can be impractical for business owners who travel frequently or work remotely. We weigh the trade-offs in Can I be my own registered agent in Colorado?, and cover the rules in full in Colorado registered agent requirements.

Many Colorado LLC owners opt for a professional registered agent service for the privacy it provides and the assurance that important legal documents will be received promptly. Some registered agent services also include compliance reminders for your Periodic Report deadline, which can be a helpful bonus feature for busy entrepreneurs.

Colorado Taxes for LLCs

Colorado does not impose a standalone "LLC franchise tax" or any minimum entity-level tax on LLCs. This is a significant advantage compared to states like California (which charges an $800 annual franchise tax) or Texas (which has a franchise/margin tax). However, your Colorado tax obligations still require careful attention because of the state's income tax and sales tax rules:

• State income tax: Colorado has a flat 4.4% state income tax rate for the 2025 tax year (it dipped to 4.25% for 2024 under a TABOR-related adjustment). LLC income passes through to members and is reported on their individual Colorado income tax returns, and every member with Colorado-source income must file a Colorado return. An LLC that elects C-corporation treatment instead pays the corporate income tax, which is the same flat 4.4% rate.
• No franchise tax: Colorado does not charge a franchise, privilege, or minimum tax on LLCs at the entity level. You only pay income tax on actual profits.
• No gross receipts tax: Unlike some states that tax total revenue, Colorado only taxes net income after allowable deductions.
• Self-employment tax: Active LLC members also owe federal self-employment tax (15.3%) on their share of LLC earnings, which covers Social Security and Medicare contributions.

If your business sells taxable goods or services in Colorado, you'll need to collect and remit Colorado sales tax. The state sales tax rate is 2.9%, but local jurisdictions (cities, counties, and special districts) add their own rates on top, which can bring the combined rate to anywhere from 4% to over 10% depending on location.

Foreign LLC Registration Fee

If your LLC was formed in another state but you will be doing business in Colorado, you need to register as a foreign LLC with the Colorado Secretary of State. You do this by filing a Statement of Foreign Entity Authority. The filing fee is $100. Our Colorado foreign LLC registration guide walks through the full process step by step.

"Doing business" in Colorado generally means having a physical presence, employees, or significant ongoing business activity in the state. Simply making occasional sales to Colorado customers from out of state may not trigger the registration requirement, but regularly soliciting business, maintaining an office, or having employees in Colorado typically does. When in doubt, consult an attorney to determine whether your activities constitute "doing business" under Colorado law.

After registration, your foreign LLC is subject to the same $25 annual Periodic Report requirement during your anniversary month. You'll also need to maintain a registered agent with a physical Colorado address, just like a domestic LLC. Failure to file the Periodic Report can result in your foreign LLC's authority being revoked, preventing you from legally transacting business in Colorado.

Typical Total Cost (Year 1 vs Ongoing)

Colorado stands out as one of the most affordable states in the nation for LLC formation and ongoing maintenance. With a $50 formation fee and a $25 annual Periodic Report, the total state fees are remarkably low. By comparison, states like California charge an $800 annual franchise tax, New York requires expensive publication requirements, and Maryland charges $300 for its annual report. Colorado's low fee structure, combined with the absence of a franchise tax or minimum tax on LLCs, makes it an exceptionally cost-effective state for small business owners.

Keep in mind that beyond state filing fees, your total cost of running a Colorado LLC may include a registered agent service, an operating agreement (recommended but not required by Colorado law), a business bank account, local business licenses, and professional services like accounting or legal counsel. However, the state's share of your ongoing costs is minimal — as little as $25 per year if you serve as your own registered agent and file your Periodic Report on time.

For entrepreneurs evaluating where to form their LLC, Colorado's combination of low fees, fast processing, an excellent online filing system, a flat income tax rate, and no franchise tax makes it one of the most business-friendly states in the country from a cost perspective.
