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.
