Colorado’s growing cities, outdoor economy and educated workforce attract many new businesses, and its LLC process is fully online and inexpensive: $50 to form and $25 a year to report. The Colorado detail that surprises newcomers is sales tax: many cities collect their own, under their own rules.
What a Colorado LLC costs
Table of Contents
| Item | Cost | When |
|---|---|---|
| Articles of Organization | $50 | At formation (online only) |
| Periodic report | $25 | Yearly, during a five-month window around your periodic report month |
| Late periodic report | $50 penalty | If filed after the window closes |
| Statement of change (agent or address updates) | Small fee | When details change |
| Trade name filing (if using a DBA) | Small fee | When registering |
The periodic report fee rose from $10 to $25 in July 2024, so older guides may show the lower figure.
Step 1: Choose your LLC name
The name must include "limited liability company", "ltd. liability company", "LLC" or "L.L.C." and be distinguishable from other names on file. Search the Secretary of State’s business database, then check federal trademarks, domains and social handles with our business name checklist.
To trade under a different name, file a statement of trade name with the Secretary of State.
Step 2: Appoint a registered agent
Every Colorado LLC needs a registered agent with a physical Colorado street address. An individual agent must be at least 18, and Colorado now requires individual agents to hold a current Colorado driver’s license or state ID, or otherwise verify Colorado residency. You can serve yourself if you qualify, or use a commercial registered agent.
Step 3: File Articles of Organization online
Colorado accepts business filings online only. File Articles of Organization through the Secretary of State’s website and pay $50. You’ll include the LLC’s name, principal office address, registered agent, and the name and address of the person forming the LLC. Filings are usually processed immediately.
Step 4: Create an operating agreement
Colorado doesn’t require you to file an operating agreement, but every LLC should have one, covering ownership, management, profit sharing and what happens when members join or leave.
Step 5: Get an EIN and open a bank account
Apply for a free EIN from the IRS online, then open a business bank account using your filed Articles and EIN. See choosing a business bank account.
Step 6: Register for state and local sales tax
Colorado’s sales tax system is one of the most complicated in the country:
- The state sales tax rate is 2.9%, collected by the Colorado Department of Revenue, along with many county and special district taxes.
- Home-rule cities, including Denver, Aurora, Boulder, Colorado Springs and many others, administer their own sales taxes, with their own licenses, rules and returns.
Register for a state sales tax license through the Department of Revenue, then check every home-rule city where you make sales. Many home-rule cities can be handled through the state’s shared sales and use tax filing system, but some require separate filings. If you sell across many Colorado cities, sales tax software is worth considering.
Step 7: File your periodic report each year
Colorado’s yearly filing is called the periodic report. Your LLC is assigned a periodic report month, the month it was formed, and you can file from two months before to two months after that month without penalty. The fee is $25, and the report must be filed online.
If the window closes without a report, your LLC becomes noncompliant and a $50 late fee applies; if it stays unfiled, the status moves to delinquent, and restoring good standing takes more paperwork.
How a Colorado LLC is taxed
By default, LLC profits pass through to the owners, who pay federal income tax, self-employment tax and Colorado’s flat 4.4% personal income tax. Multi-member LLCs taxed as partnerships file a Colorado partnership return. Colorado also lets eligible pass-through entities elect to pay tax at the entity level. LLCs electing C corporation status pay Colorado corporate income tax. Some counties also tax business personal property above an exemption threshold. Ask a tax professional what applies to you.
Hiring your first employee in Colorado
Beyond the federal steps in our first employee guide, Colorado employers generally:
- Register for state withholding with the Department of Revenue and unemployment insurance with the Department of Labor and Employment.
- Carry workers’ compensation insurance once they have employees.
- Pay premiums for FAMLI, Colorado’s paid family and medical leave insurance program.
- Provide paid sick leave under Colorado law and follow the state’s minimum wage, which some cities, including Denver, set higher.
- Report new hires to the state.

Colorado rules for common types of business
Contractors. Colorado doesn’t license general contractors statewide; cities and counties, including Denver, license contractors locally. Electricians and plumbers need state licenses. See our home services industry profile.
Food businesses. Restaurants and food trucks are licensed by local health agencies. Colorado’s cottage food rules let some home cooks sell certain foods directly to consumers. See our cottage food business guide.
Outdoor and tourism businesses. Guides, outfitters and tour operators may need state registrations or permits on public land, plus local licenses. See our ideas for outdoor adventure businesses.
Childcare. Child care centers and family child care homes are licensed by the state’s early childhood department. See our home daycare guide.
Colorado compared with nearby states
| State | Filing fee | Yearly state report | State income tax |
|---|---|---|---|
| Colorado | $50 | $25 periodic report | Flat 4.4% |
| Wyoming | $100 | $60 minimum | None |
| Utah | Low filing fee | Yearly renewal | Flat rate |
| Arizona | $50 | None | Flat 2.5% |
| New Mexico | Low filing fee | None | Graduated |
Some Colorado founders consider forming in Wyoming for its lack of income tax. If you live and work in Colorado, though, your LLC still has to register here and you’ll still pay Colorado income tax on your earnings, so forming at home is usually simpler. See our Wyoming and Arizona guides for comparison.
A sales tax example
Suppose you run a small online shop from Colorado Springs and ship to customers across the state. You’d generally register with the Department of Revenue for state sales tax and the state-collected local taxes, register with Colorado Springs as a home-rule city, and check whether other home-rule cities where your customers live require you to collect their tax too. Tracking where each order is delivered from day one makes filing far easier.
Mistakes to avoid
- Missing the periodic report window, which runs around your formation month.
- Registering only for state sales tax when you also sell in home-rule cities.
- Naming an individual registered agent who doesn’t meet Colorado’s ID rules.
- Relying on old guides that show the former $10 report fee.
- Forgetting FAMLI premiums when you hire.
Frequently asked questions
How long does it take to form a Colorado LLC? Online filings are generally processed almost immediately.
Can I file by mail? No. Colorado business filings are online only.
When is my first periodic report due? In the window around your periodic report month in the year after formation. The Secretary of State’s records show your month.
Can I be my own registered agent? Yes, if you have a physical Colorado address and meet the state’s ID or residency requirements.
Does Colorado dissolve LLCs for missing reports? An LLC that stays delinquent for an extended period can eventually be administratively dissolved, so it’s best to file each year within the window.
