Running a Colorado business comes down to early decisions that shape your liability and taxes: which entity to form, how to file and maintain it with the state, and the contracts that keep it running. The guides below walk through each step.
Entity types
Colorado businesses commonly operate as sole proprietorships or general partnerships (which need no formation filing), LLCs (Colorado Limited Liability Company Act, C.R.S. § 7-80-101 et seq.), or corporations (Colorado Business Corporation Act, C.R.S. Title 7, Articles 101–117). LLCs and corporations generally shield owners’ personal assets, while a sole proprietor or general partner does not have that shield.
Forming with the Colorado Secretary of State
LLCs and corporations are created by filing with the Colorado Secretary of State. Filings are done online through the Secretary of State — online filings are processed in real time and cost less than paper. State filing fees apply; always confirm current fees on the Secretary of State site (coloradosos.gov) before filing.
The annual periodic report
After formation, most Colorado entities must keep a registered agent and file a periodic report with the Secretary of State each year to stay in good standing. Periodic-report fees apply — confirm the current fee on coloradosos.gov.
Contracts
Most Colorado deals run on contracts. Some agreements must be in writing to be enforceable, and there are deadlines to sue if a contract is broken.

Guides
- Business Disputes in Colorado
When a contract is breached in Colorado, remedies include money damages and, where damages are inadequate, specific performance. Deadlines matter: most contract actions must be brought within 3 years (C.R.S. § 13-80-101), but actions to collect a liquidated or determinable debt have 6 years (C.R.S. § 13-80-103.5). Where there's doubt, Colorado courts favor the longer period. Confirm current deadlines before relying on them.
- Choosing a Business Entity in Colorado
Colorado business owners choose among sole proprietorships and general partnerships (no formation filing), LLCs (Colorado Limited Liability Company Act, C.R.S. § 7-80-101 et seq.), and corporations (Colorado Business Corporation Act, C.R.S. Title 7, Articles 101–117). LLCs and corporations are formed by filing with the Secretary of State and generally shield owners' personal assets. LLCs and partnerships are usually pass-through for tax; corporations are taxed at the entity level unless they make a federal S-corp election.
- Contract Basics in Colorado
A contract needs offer, acceptance, and consideration. Colorado's statute of frauds (C.R.S. § 38-10-112) requires a signed writing for certain agreements — including those not to be performed within one year, a promise to answer for another's debt, and agreements in consideration of marriage. A contract for the sale of land or an interest in land must be in writing under a separate section (C.R.S. § 38-10-108).
- How to Form a Corporation in Colorado
To form a Colorado corporation you file Articles of Incorporation under the Colorado Business Corporation Act (C.R.S. § 7-102-102), stating the corporate name, authorized shares, registered agent, principal office, and incorporators. The corporation must maintain a registered agent (C.R.S. § 7-90-701) and file the periodic report (C.R.S. § 7-90-501). An 'S corporation' is a federal tax election with the IRS, not a separate Colorado entity. Fees apply; confirm current amounts on coloradosos.gov.
- How to Form an LLC in Colorado
To form a Colorado LLC you file Articles of Organization with the Colorado Secretary of State under C.R.S. § 7-80-204, stating the LLC name, principal office, registered agent, and management structure. The LLC must continuously maintain a registered agent (C.R.S. § 7-90-701) and file a periodic report (C.R.S. § 7-90-501) — first due by the last day of the second month after the first anniversary, then annually. Filing and periodic-report fees apply; confirm current fees on coloradosos.gov.
- Trade Name (DBA) Registration in Colorado
A person or entity transacting business in Colorado under a name other than its true name must file a Statement of Trade Name with the Colorado Secretary of State (C.R.S. § 7-71-101). Unlike some states, Colorado has no newspaper-publication requirement — it's just a Secretary of State filing. Fees apply; confirm current amounts on coloradosos.gov.
