Licenses & Permits in Colorado

General Business License

Colorado does not have a statewide general business license requirement. Businesses must register their entity with the Colorado Secretary of State and obtain a sales tax license from the Colorado Department of Revenue if selling taxable goods or services. Many municipalities require a local business license — Denver, Aurora, Colorado Springs, and Boulder all have their own business licensing programs with state-set annual fees that vary by program.

Home-Based Business Rules

Colorado municipalities regulate home-based businesses through local zoning ordinances. Denver allows home occupations with restrictions on customer visits (typically 1 person at a time), no exterior display, and no storage of commercial vehicles. Colorado State law preempts local regulations that would completely prohibit home-based businesses. The Colorado Cottage Food Act specifically authorizes home-based food production with certain limitations.

Frequently Asked Questions

Starting an accounting firm typically requires a low-to-mid five-figure investment, covering CPA licensing, professional liability insurance, tax software, and initial marketing. Home-based practices can launch at the lower end of that range.

You don't need a CPA license to offer bookkeeping services, but you must be a licensed CPA to offer auditing services or sign tax returns as a paid preparer. Using 'CPA' in your firm name typically requires a licensed CPA as the majority owner.

Drake Tax (https://www.drakesoftware.com/products/drake-tax/) is popular for solo practices, billed as an annual subscription scaled to feature tier. Lacerte and ProSeries are preferred by larger firms. UltraTax is common at mid-size firms. All handle individual and business returns.

A solo CPA charging a healthy three-figure hourly rate can be profitable with a few dozen regular business clients or roughly 100-150 individual tax clients. The key is mix — monthly bookkeeping retainers provide predictable revenue, while tax season creates seasonal peaks.
