  1. Colorado Master Electrician License

    Colorado requires a Master Electrician License issued by the Colorado State Electrical Board (DORA Division of Professions and Occupations) for anyone qualifying an electrical contracting business. Applicants need four years of experience (two as a journeyman) and must pass a state exam. Colorado electrician licenses are renewed on a three-year cycle with continuing education completed during each three-year license period.

  2. Insurance for a Colorado Electrical Contractor

    Colorado does not set a general liability insurance minimum for electrical contractors, and Denver's published contractor licence application steps do not require proof of liability insurance - they require a supervisor certificate holder or a Colorado electrical licence, a Supervisor Statement of Responsibility, Secretary of State documents, and a current State of Colorado Electrical Contractor card with the Master Electrician's ID. Denver's contractor licensing is run by Community Planning and Development, not by the Department of Licensing and Consumer Protection (the renamed Excise and Licenses). What is mandatory is workers' compensation: under C.R.S. 8-44-101 an employer must secure coverage through Pinnacol Assurance, an authorised insurer or an approved self-insurance permit. Carry general liability anyway - customers, general contractors and property owners routinely require a certificate of insurance and set their own limits.

    Official government source

    Premiums are set by insurers based on payroll, trade classification and claims history; no state agency publishes a rate. Note that Denver charges no fee for the electrical contractor licence itself ($0.00 on its contractor licensing fee schedule), while other construction licence classes are $250 for three years.Liability and commercial auto policies can usually be bound within a day or two. Workers' compensation must be in force before the first employee starts. Denver contractor licence applications submitted online take about 14-20 business days to review.

  3. Colorado Business Entity Registration (if applicable)

    LLCs and corporations must register with the Colorado Secretary of State.

City of Denver / Denver County

2 stops

  1. Denver Electrical Contractor License

    Denver requires a city-issued electrical contractor license from Community Planning and Development, separate from the individual state electrician license. A Colorado state electrical license substitutes for the Denver supervisor certificate, so the business must be qualified by someone holding a current Colorado electrician license. Denver does not accept or reciprocate contractor licenses from other counties or states. Apply through the Denver e-permits (contractor licensing) portal.

    Official government source

    $0.00 — Denver charges no fee for the electrical contractor license itself; the underlying Colorado state electrician license has its own feeRenewed every 3 years; the license issues once Contractor Licensing approves the application and the qualifying state license is verified

  2. Denver Retailer's Sales, Use, Lodger's Tax License

    Denver is a home-rule city that collects and administers its own taxes, so an electrical contractor selling materials as part of its work registers separately with Denver's Treasury Division (Department of Finance) for a Retailer's Sales, Use, Lodger's Tax License - the state licence does not cover Denver. Register and file through Denver's eBiz Tax Center; sales and use tax returns may alternatively be filed through Colorado's SUTS portal using Denver jurisdiction code 01-0006. Contractors also owe Denver consumer's use tax on materials and equipment used in the city on which sufficient sales tax was not paid; Treasury publishes a tax guide for general contractors and subcontractors doing construction within Denver.

    Official government source

    No fee. Denver states it no longer charges a licence fee with the biennial Retailer's Sales, Use, Lodger's Tax License. Denver's general sales/use rate is 5.15%, on top of 2.9% state, 1.0% RTD and 0.1% special district for a 9.15% combined rate.Registration is completed online in the eBiz Tax Center; Treasury mails licences on December 1 each year. If you file through SUTS without a Denver account, a local tax account is created for you from the filing data.
