How much does it cost to start an LLC in Colorado?

The Colorado Secretary of State charges a $50 filing fee for the Articles of Organization. Your total first-year cost is just $75 when you add the $25 periodic report fee due during your anniversary month. For example, if you form your LLC in April, your first periodic report and $25 fee are due the following April. Additional costs may include registered agent services and business licenses depending on your industry. There's no newspaper publication requirement in Colorado, saving you additional money. Exception: professional LLCs in fields like medicine or law must also obtain the relevant state professional license before operating, adding to your overall startup expenses. File your Articles of Organization online at sos.state.co.us to receive same-day processing confirmation and the fastest possible approval.

How long does it take to form an LLC in Colorado?

Colorado publishes this figure, which many states do not: instant (online filing only). In the Colorado Secretary of State's own words: "Documents filed online are processed in real time and are available immediately after successful payment.". Treat this as a genuine planning figure rather than a guarantee, and confirm it on the Colorado Secretary of State's own site before committing to a date.

Do I need to publish my Colorado LLC formation in a newspaper?

No, Colorado doesn't require LLCs to publish a formation notice in any newspaper. Once the Colorado Secretary of State approves your Articles of Organization, your LLC is legally formed and ready to conduct business without any additional publication step. This is a significant cost advantage compared to states like New York, where mandatory newspaper publication is charged at rates the newspapers set. Arizona requires a newspaper notice of a new LLC's formation, run three consecutive times within 60 days, unless the LLC's statutory agent has a street address in a county of more than 800,000 people (currently Maricopa and Pima Counties), where the Arizona Corporation Commission posts the notice online for free. Exception: certain regulated professions in Colorado may have their own public disclosure requirements as part of a professional licensing process. Check with your industry's governing board if you operate in a licensed field. To confirm your LLC is officially formed, wait for the digital or paper approval notice from the Colorado Secretary of State before entering any contracts on behalf of the LLC.

What is Colorado's annual report requirement for LLCs?

Colorado LLCs must file a periodic report, commonly called an annual report, during the anniversary month of formation each year, with a $25 filing fee paid to the Colorado Secretary of State. For example, if your LLC was formed in August, your periodic report is due each August, every year. The report confirms your registered agent's name and address and your LLC's principal office address. Filing online through the Secretary of State's portal is the recommended method for immediate confirmation. Exception: if you miss your anniversary month, Colorado provides a two-month grace period through the end of the following month before administrative dissolution proceedings begin, but filing on time avoids any risk. Late fees may also apply. Set a recurring annual reminder for your formation anniversary month to ensure timely filing every year at sos.state.co.us.

Can I be my own registered agent in Colorado?

Yes, any Colorado LLC owner may serve as their own registered agent provided they maintain a physical Colorado street address, P.O. boxes aren't permitted, and are consistently available during normal business hours to receive legal documents on the LLC's behalf. For example, a Denver-based entrepreneur with a home office can list that address and act as their own registered agent at no additional cost. Exception: if you travel frequently, work primarily outside Colorado, or can't guarantee a daytime presence at your listed address, serving as your own registered agent is risky. A missed service of legal process can result in a default judgment against your business. Professional registered agent services are available for a yearly fee and provide privacy by removing your personal address from public records. Update any registered agent changes promptly with the Colorado Secretary of State to remain in good standing.

Does Colorado have state income tax for LLCs?

Yes. Colorado taxes LLC members on their share of the profit through its personal income tax. Check the current rate with the state tax agency. Because most LLCs are pass-through entities, the LLC itself doesn't pay state income tax, instead, each member reports their share of LLC profits on their personal Colorado state income tax return. Exception: an LLC that elects to be taxed as a corporation may be taxed differently by Colorado, so check with the state tax agency or a tax professional before electing. Local income taxes may also apply depending on your municipality. Consult a Colorado tax professional about estimated quarterly state income tax payments.

How to Form an LLC: Step-by-Step

1
Choose Your Colorado LLC Name
Your LLC name must include 'Limited Liability Company,' 'LLC,' or 'L.L.C.' and be distinguishable from existing business names in Colorado. Check name availability using the Colorado Secretary of State's business database before proceeding.
How to search Colorado's business entity records →
Pro tip: Reserve your chosen name for 120 days by filing a name reservation for $25 if you need time to complete your formation paperwork.
2
Designate a Registered Agent
Colorado requires every LLC to have a registered agent with a physical Colorado address who can receive legal documents during business hours. You can serve as your own registered agent or hire a professional service.
Colorado registered agent rules, costs and options →
Pro tip: A professional registered agent service puts its address, not yours, on the registered agent line of the public filing, and accepts legal papers during business hours.
3
File Articles of Organization
Submit your Articles of Organization to the Colorado Secretary of State along with the $50 filing fee. You can file online, by mail, or in person. The document requires basic information including your LLC name, registered agent details, and organizer information.
What You File in Colorado
In Colorado, the formation document is the Articles of Organization, filed with the Colorado Secretary of State. The state filing fee is $50. Colorado lets you fill in and file the Articles of Organization online. The state's published processing time: Instant (online filing only). The form itself requires the LLC's name, the registered agent's name, the registered office address, the principal office address, a mailing address, the organizer's name, whether the LLC is member-managed or manager-managed and the registered agent's consent. Every line of the Articles of Organization, field by field →
Processing Times

- Mail: Not available. Articles of Organization can only be filed electronically
- Expedited: No paid expedite option is published for LLC filings
Pro tip: Colorado only accepts Articles of Organization electronically, and its own fee schedule states that documents filed online “are processed in real time and are available immediately after successful payment”, so there's no waiting period to plan around.
4
Create an Operating Agreement
This page has not confirmed whether Colorado law requires an LLC to have an operating agreement. A written agreement signed by every member is worth having either way: it records who owns what share, who makes decisions and how profits are divided. This document outlines ownership percentages, profit distributions, and management structure.

Pro tip: Even single-member LLCs benefit from operating agreements to maintain separation between personal and business assets for legal protection.
5
Obtain Your Federal EIN
Apply for an Employer Identification Number (EIN) from the IRS, which serves as your business tax ID. You can apply online for free directly through the IRS website. This number is required for business banking and tax filings.

Pro tip: Apply for your EIN immediately after your Articles of Organization are approved - you'll need it to open a business bank account and establish business credit.
6
Open a Business Bank Account
Separate your personal and business finances by opening a dedicated business bank account. Bring your Articles of Organization, EIN confirmation letter, and operating agreement to the bank. This separation matters for maintaining your LLC's liability protection.

Pro tip: Shop around for business banking options - many Colorado banks offer special programs for new small businesses with reduced fees and minimum balances.
7
Obtain Required Business Licenses
Research and obtain any business licenses or permits required for your specific industry or location in Colorado. Check with both state agencies and your local city or county for applicable requirements. Some businesses may also need federal licenses.

It reports what each Secretary of State publishes for forming an LLC, with the sources this page cites. It cannot tell you what your own filing needs: fees and forms change between our reviews, several occupations cannot use an ordinary LLC at all and must use a professional entity, and your city or county may require a registration of its own. Confirm the current fee and form with the filing office named on this page before you send anything.
