| Cost Item | Amount | When Due |
|---|---|---|
| Colorado Filing Fee | $50 | One-time at formation |
| Periodic report | $10 | Annually |
| Registered Agent Service | $49 to $300/year | Annually |

Colorado cities do not levy a local business income tax, but Denver imposes an Occupational Privilege Tax (a flat monthly head tax of $5.75 per employee earning over $500 a month, plus $4.00 per covered employee paid by the business) and requires a business and sales tax license. Budget for the OPT and the Colorado periodic report fee on top of the state LLC filing fee.
Denver is the capital and economic center of Colorado and the Mountain West, with an economy spanning aerospace and defense, energy, financial services, healthcare, a major federal presence, and a fast-growing technology and outdoor-recreation industry along the Front Range.

The LLC filing fee is set by Colorado at $50, since LLCs are formed at the state level. Add the $10 periodic report (each year), a registered agent (about $49 to $300/year), and any local Denver business license or tax. Colorado cities do not levy a local business income tax, but Denver imposes an Occupational Privilege Tax (a flat monthly head tax of $5.75 per employee earning over $500 a month, plus $4.00 per covered employee paid by the business) and requires a business and sales tax license. Budget for the OPT and the Colorado periodic report fee on top of the state LLC filing fee.

Plan for the $10 periodic report, registered agent renewal (about $49/year), and any local Denver business license or tax. The calculator above totals these for you.
LLCs are registered with the Colorado Department of Revenue at the state level, not the city. You then comply with local Denver requirements such as a business license, zoning, and any city business tax. There is no separate city-level LLC filing.
If your business actually operates in Denver, forming in Colorado is usually simplest. Forming in Delaware or Wyoming while operating in Denver typically forces you to register as a foreign LLC in Colorado anyway, paying fees in both states.
