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 fees ranging from $25 to $500 annually.

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

A tax preparation business can start for $5,000–$15,000, with the main costs being tax software ($600–$1,800/year), PTIN registration ($19.95/year), office equipment ($500–$1,500), and marketing. Home-based operations eliminate office rent entirely.

No — anyone can prepare federal taxes for compensation if they register for a PTIN. However, CPAs, EAs, and attorneys can represent clients before the IRS, charge higher rates, and are subject to continuing education requirements. Oregon and California require state licensing for all paid preparers.

Average fees nationally are $220 for individual returns and $800–$1,500 for business returns. Complex individual returns (rental income, self-employment, investments) command $300–$500+. Your market and credential level determine acceptable pricing.

Tax season runs January 15 – April 15 with an extended September 15 deadline for extensions. Most revenue is earned in 3 months. Successful preparers build year-round income from amended returns, IRS notices, bookkeeping, and payroll services.
