How to Start an LLC in Colorado (2026): Step-by-Step Guide

Published: June 2026 · Updated for the 2026 tax year

Colorado is one of the cheapest and fastest states to start an LLC — $50 to file, online only, approved in minutes, with a tiny annual report and a flat state income tax. This guide walks through every step, what a Colorado LLC actually costs (year by year, not just the headline filing fee), how to form one from outside the US, and the one number almost every other article gets wrong.

A note from Slava

I'm Slava, co-founder and CEO of Jupid. Before this I co-founded and scaled an AI-powered accounting platform to around $30M in revenue and more than 100,000 business users — the kind of company that ends up filing a lot of paperwork in a lot of states and watching customers trip over the same potholes again and again.

Colorado is the easy one. After California's $800 and the two-state mess Delaware creates for most people, Colorado feels like a relief: $50, online, done in minutes, and a flat 4.4% income tax with no franchise tax bolted on. The catch isn't a hidden fee — it's a stale one. The annual periodic report went from $10 to $25 on July 1, 2024, and a huge share of "how to start an LLC in Colorado" articles (and calculators) still quote $10. It's a small dollar difference, but it's the kind of thing that tells you whether a guide was actually checked this year or copied from an old one.

So this guide does the usual job — the steps, the real costs year by year, the non-resident path, and a dated checklist for your first 90 days — and it gets the small numbers right, because the small numbers are the whole point in a cheap state. Everything here is current for 2026, with links to the official sources so you can verify before you file.

Should you actually form your LLC in Colorado?

If you live in Colorado and run your business from Colorado, you should almost certainly form your LLC in Colorado. The popular advice to "form in Wyoming or Delaware instead" doesn't help you here: an out-of-state LLC that does business in Colorado has to register as a foreign LLC with the Secretary of State anyway — a $100 filing, a second registered agent, and a second set of annual reports — so you end up paying more for more paperwork, with no tax saving, because Colorado taxes the income you earn here regardless of where the LLC was born.

Forming elsewhere makes sense in a narrower set of cases: you genuinely don't operate in Colorado (no office, employees, or significant activity here), you're a non-resident with no US footprint at all and want a privacy-friendly home state, or you have a specific reason — outside-investor expectations, for instance — that points to Delaware. If you're weighing it, our best state to form an LLC tool walks through the trade-offs, and our Wyoming LLC guide covers the no-state-income-tax, non-resident case in detail.

For everyone else — and especially for Colorado residents and small businesses that operate here — Colorado is both the obvious and the cheap choice. Here's how.

How to start an LLC in Colorado, step by step

1. Choose and check your LLC name

Your name has to include "Limited Liability Company," "Limited Liability Co.," "Ltd. Liability Company," "Limited," "LLC," or "L.L.C." ("Limited" can be shortened to "Ltd." and "Company" to "Co."), and it has to be distinguishable from every other entity on the Secretary of State's records. Search the Colorado business database before you get attached to anything. Need ideas or want to check a few options at once? Our Colorado business name generator is built for exactly that. If you want to lock a name in before you're ready to file, a Statement of Reservation of Name holds it for 120 days for $25.

2. Appoint a Colorado registered agent

Every Colorado LLC needs a registered agent who can accept legal papers on its behalf. That agent is either an individual who is at least 18 and primarily resides in Colorado, or a business entity with a usual place of business in Colorado that has consented to serve — and in both cases the agent needs a physical Colorado street address, not a P.O. box on its own. You can serve as your own LLC's agent if you live in Colorado. The agent's name and address become public record, which is one reason people who'd rather not publish a home address (and everyone who lives out of state) hire a commercial registered agent for roughly $50–$150 a year.

3. File the Articles of Organization online

This is the step that creates your LLC. File the Articles of Organization through coloradosos.gov for $50. Colorado is online-only — there is no paper LLC filing, no mail-in option, no in-person counter for this — so you'll do it on the state's website and pay by card. You'll list the LLC name, the registered agent's name and Colorado address, the principal office address, the management structure, and the organizer's name. The big upside of online-only: approval is usually immediate, and your LLC is on the public record within minutes. Download the stamped copy once it's filed — your bank will ask for it.

4. Write an operating agreement

Colorado doesn't require you to file an operating agreement and won't ask to see one — but you should have it, in writing. It sets out ownership percentages, how profits are split, who can make decisions, and what happens if a member leaves. Even a single-member LLC should have one: it's part of how you keep the liability shield intact, and most banks will want to see it when you open an account. Keep it with your company records.

5. Get your EIN from the IRS

An EIN is your LLC's federal tax ID, and you need it to open a bank account, hire anyone, and file taxes. It's free, and the Colorado Secretary of State doesn't issue it — the IRS does. Apply at irs.gov — if you have an SSN or ITIN, the online application takes a few minutes. If you don't (common for non-resident owners), file Form SS-4 by fax or mail with "Foreign" written on the responsible-party line, or call the IRS international EIN line; see the non-resident section below. Never pay a third party for the EIN itself — the number is always free from the IRS.

6. Calendar the $25 periodic report

Colorado's version of an annual report is the periodic report, and it's cheap and simple — $25 a year, online only. It's due based on your LLC's "periodic report month," which is the month it was formed (your anniversary month). You can file it in a five-month window — anytime from two months before through two months after that month — with no penalty. File late and there's a $50 penalty, and your LLC's status flips to "delinquent," which puts your good standing at risk. (Set a reminder; the state sends courtesy notices, but you're responsible whether or not one arrives.) Note the fee: it was $10 until July 1, 2024, and is now $25 — ignore any article that still says $10.

7. Register for Colorado taxes and any local licenses

Forming the LLC doesn't cover your tax and local obligations. The fastest route to most of them is MyBizColorado, which routes you to the right state agencies. If you sell tangible goods or taxable services with Colorado nexus, register for a Colorado sales tax license (about $16 for a two-year license, prorated, plus a $50 deposit that's refunded once you've remitted $50 in state sales tax). Note that Colorado is a home-rule state — cities like Denver and Boulder administer their own sales tax separately, and as of January 1, 2026 the state's vendor service-fee discount has been eliminated, so you remit 100% of the state tax you collect. If you'll have employees, register for wage withholding with the Department of Revenue and for unemployment insurance and FAMLI (paid leave) with the Colorado Department of Labor and Employment. And any professional or industry license you'd need as a sole proprietor — many are issued through DORA or your city — you still need as an LLC.

What a Colorado LLC really costs, year by year

Most guides quote "$50 and you're done" and stop. Here's the fuller picture — and yes, the periodic report is $25, not $10.

Year one

Every following year

The timing insight nobody flags. Colorado has no franchise tax and no "minimum annual tax," so there's no California-style "double $800" trap and no penalty for forming in December. Your first periodic report isn't due until a window around your next anniversary month, so a brand-new Colorado LLC's first 12 months can cost as little as the $50 filing fee if you act as your own registered agent. The real recurring cost in Colorado isn't a state fee at all — it's the bookkeeping and the income tax on your profit. Plan around those, not around the (tiny) periodic report.

DIY versus a formation service versus Jupid. Doing it yourself costs the $50 filing fee and your time. A formation service charges $0–$300 on top of the state fees (the "$0" packages still pass through the $50 and then upsell you a registered agent and a "compliance" subscription). Jupid forms your Colorado LLC for free — you pay only the state filing fee — and then handles the bookkeeping and tax filings afterward, which is where most of the ongoing cost and hassle actually lives. To model the annual numbers for your situation, use our Colorado LLC annual cost calculator.

Forming a Colorado LLC as a non-resident or foreign founder

You can own a Colorado LLC without being a US citizen or resident — Colorado imposes no residency requirement on members or managers. The cheap-and-fast filing is the same for you. The practical hurdles are a Colorado registered agent, an EIN, a US bank account, and your US and Colorado tax filings.

Registered agent. If no member or manager lives in Colorado with a real street address, you must use a commercial registered agent here. Budget around $50–$150 a year. P.O. boxes and mailbox-store addresses don't qualify on their own, and the agent has to consent to the appointment.

Getting an EIN without an SSN. The IRS online EIN tool requires the responsible party to have an SSN or ITIN, so foreign founders generally can't use it. Instead, file Form SS-4: on the line asking for the responsible party's SSN/ITIN/EIN, write "Foreign" — don't invent a number. Submit it by fax or mail, or call the IRS international EIN line (it's not toll-free), where someone outside the US can get the number over the phone. Check the current Form SS-4 instructions for the right fax and phone numbers, since the IRS changes them. The EIN is free, and the Colorado Secretary of State doesn't issue it.

ITIN. An ITIN (Form W-7) is a tax ID for individuals who aren't eligible for an SSN. Your LLC gets an EIN; you as an owner may separately need an ITIN if you have to file a personal US return. ITINs are issued with a tax return attached or through an IRS Certifying Acceptance Agent and can take a couple of months.

The Form 5472 obligation — don't skip this. A single-member LLC owned by a non-US person is a "disregarded entity" that generally must file Form 5472 along with a pro-forma Form 1120 every year, reporting transactions between the LLC and its foreign owner — including the money you put in to capitalize it. This is an information return, not an income tax return, and it's required even with zero revenue. The penalty for missing it is $25,000. A foreign-owned multi-member LLC files Form 1065 instead. Almost no Colorado LLC guide mentions this; build it into your annual calendar from day one.

US bank account. Most US banks want the owner physically present to open a business account, along with the EIN confirmation letter, the filed Articles of Organization, the operating agreement, and a passport. Several fintech business-banking platforms onboard non-resident-owned US LLCs remotely — eligibility and policies change, so check current terms before you rely on any of them. This tends to be the most friction-prone step.

Colorado tax. Colorado's 4.4% flat rate applies to Colorado-source income. A nonresident member with Colorado-source income may owe Colorado nonresident income tax, and the LLC may have to file a composite return or withhold on Colorado-source income allocated to nonresident members. Federally, if the LLC is engaged in a US trade or business, the foreign owner has US filing obligations of their own (Form 1040-NR for an individual, plus the Form 5472 filing above). A US cross-border CPA is worth the consultation here.

Registered agents and the Corporate Transparency Act (BOI)

Your registered agent is the person or company designated to receive lawsuits and official notices for the LLC. In Colorado it has to be an individual 18 or older who lives in the state, or a business with a Colorado office, with a physical street address — and because the agent's address is public, plenty of Colorado residents hire a commercial agent purely to keep their home address off the record.

On the federal beneficial-ownership side: under the Corporate Transparency Act, LLCs were originally required to file a Beneficial Ownership Information (BOI) report with FinCEN. That changed. FinCEN's interim final rule, published in March 2025, redefined a "reporting company" to mean only entities formed under foreign law that register to do business in a US state. As of early 2026, that means a Colorado-formed LLC — even one with foreign owners — has no BOI filing obligation. Older articles still tell you to "file within 30 days"; that's now wrong for domestic LLCs. FinCEN has said it intends to finalize the rule, so this could shift; check fincen.gov/boi before you assume one way or the other. (If you register a foreign-formed entity to do business in Colorado, that entity may still have a BOI deadline.)

Your first 30, 60, and 90 days

Days 1–7

• Get your EIN from the IRS (free; online if you have an SSN/ITIN, otherwise by fax or mail with "Foreign" on the responsible-party line).
• Adopt your operating agreement in writing — not filed with Colorado, but banks expect it.
• Check your BOI status. As of early 2026 a domestic Colorado LLC has no FinCEN filing to make; re-verify at fincen.gov/boi.

Days 1–30

• Open a US business bank account (EIN letter, filed Articles, operating agreement, ID).
• If you sell taxable goods, register for a Colorado sales tax license via MyBizColorado — and check whether your home-rule city (Denver, Boulder, and others) needs a separate local sales tax license.
• Register for wage withholding and unemployment insurance (and FAMLI) if you'll hire, and set up federal payroll.
• Get any professional or industry license your work requires — check DORA and your city or county.
• Look into business insurance — general liability now, workers' comp once you have employees.

Days 30–60

• Set up bookkeeping and keep personal and business finances strictly separate — that separation is what holds up the limited-liability shield.
• Note your LLC's anniversary month so the periodic report window doesn't catch you.
• If you're a foreign-owned single-member LLC, put the annual Form 5472 + pro-forma 1120 filing on your calendar now.

Days 60–90

• Decide on federal tax classification — default (disregarded/partnership) versus an S-corp election (Form 2553), typically worth modeling once profit clears roughly $40k–$50k.
• If you're profitable and taxed as a partnership or S-corp, ask your CPA whether Colorado's SALT Parity Act election (an entity-level PTET, made on Form DR 0106 or DR 1705) saves you money on your federal return.
• Calendar the recurring deadline: the $25 periodic report, due in the window around your anniversary month every year.

Common mistakes with Colorado LLCs

Trusting the old "$10 annual report" number. Why it hurts: it signals you're working from out-of-date information, and if you budgeted or filed off a stale source you can underpay and slide into "delinquent." Fix: the periodic report is $25 as of July 1, 2024 — file it online and pay the current fee.

Letting the LLC go "delinquent." Why it hurts: miss the periodic report window and it's a $50 penalty, your status flips to delinquent, and continued failure leads to administrative dissolution — which freezes your ability to do business under the LLC and to enforce contracts. Fix: file the periodic report in its five-month window; if you've already gone delinquent, cure it promptly (a Statement Curing Delinquency or reinstatement is $100).

Thinking a Wyoming LLC dodges Colorado tax. Why it hurts: if you operate in Colorado, the out-of-state LLC has to register here as a foreign LLC, so you owe Colorado income tax on Colorado-source income anyway — plus the other state's fees and a second registered agent. Fix: if Colorado is where you do business, form in Colorado.

Forgetting Colorado's home-rule city sales taxes. Why it hurts: getting a state sales tax license isn't enough — home-rule cities like Denver run their own systems, and missing a local registration means unpaid local tax piling up. Fix: check both the state and your specific city/county before you start selling taxable goods; MyBizColorado helps route this.

Frequently asked questions

How much does it cost to start an LLC in Colorado in 2026? The state filing fee for the Articles of Organization is $50, filed online. After that, the only required recurring state fee is the $25 annual periodic report. If you don't live in Colorado you'll also pay a commercial registered agent, typically $50–$150 a year. There is no franchise tax and no annual minimum tax.

Is the Colorado periodic report fee really $25 now, not $10? Yes. Colorado raised the periodic report fee from $10 to $25 effective July 1, 2024. Many articles — and a lot of older calculators — still say $10. The current fee on the Secretary of State's official fee schedule is $25, due once a year in a window around your LLC's anniversary month.

Do I need a registered agent for a Colorado LLC? Yes. Every Colorado LLC must have a registered agent with a physical Colorado street address — either an individual who is 18 or older and lives in Colorado, or a business authorized to operate in Colorado. You can be your own agent if you live there; if you don't, you'll hire a commercial registered agent for roughly $50–$150 a year.

Can a non-US resident form a Colorado LLC? Yes. Colorado has no citizenship or residency requirement for members or managers. You'll need a commercial Colorado registered agent and an EIN (which you can get without an SSN by filing Form SS-4). If you're the sole owner, the LLC must file Form 5472 with a pro-forma Form 1120 every year — the penalty for missing it is $25,000.

Does Colorado require LLCs to publish a formation notice in a newspaper? No. Unlike New York, Arizona, Nebraska, Georgia, and Pennsylvania, Colorado has no newspaper publication requirement for LLCs.

How long does it take to form an LLC in Colorado? Usually minutes. Colorado filings are online only, and the Articles of Organization are typically accepted and effective as soon as your payment clears, putting your LLC on the public record the same day. That makes Colorado one of the fastest states to form in.
