Form the business and get an EIN.
The Colorado Department of Regulatory Agencies — State Electrical Board issues the Residential Wireman / Journeyman / Master Electrician; the business that invoices Colorado customers is a separate decision. A sole proprietorship is the default, an LLC keeps business liability off your personal assets, and either needs an EIN before the first payroll. Settle it before the license number goes on an estimate.
Bond: none required by the state.
Colorado does not require a surety bond for this license — No statewide surety bond required by DORA for electrician licenses. Some local jurisdictions may require a bond for electrical contractors operating within their area.
