Licenses & Permits in Wisconsin
General Business License
Wisconsin does not have a statewide general business license. Businesses must register their entity with the Wisconsin Department of Financial Institutions and register with the Wisconsin Department of Revenue for sales and use tax and withholding tax purposes. Some Wisconsin municipalities require local business licenses, though this varies. Milwaukee, Madison, and Green Bay have their own licensing requirements. Wisconsin's one-stop portal at DFI.wi.gov helps streamline business registration.

Common Mistakes to Avoid
- 1
Starting without a master electrician license — unlicensed electrical work is illegal and creates severe liability
- 2
Not building general contractor relationships from day one — GC subcontract work is the fastest growth path
- 3
Undercharging for panel upgrades — a 200A panel upgrade is a multi-hour skilled-labor job and pricing should reflect both the hours and the licensed-trade nature of the work
- 4
Not obtaining permits for permitted work — homeowners can face major issues at sale if work was unpermitted
- 5
Not tracking material costs per job — material markup is a significant profit center for electrical contractors
Next Steps to Launch Your Electrical Business

Form your LLC in Wisconsin — electricians face significant liability for fire and injury from faulty wiring; entity protection is essential (filing fee: $130)

Obtain your Wisconsin electrical contractor license — requires master electrician license (typically several years of journeyman experience plus state exam) in most states

Obtain a contractor surety bond at the face value required by your state and electrical contractor liability insurance; premiums scale with payroll

Complete OSHA 10 or 30-hour construction safety training — required by most general contractors before working on their job sites

Register with your local utility company as an approved electrical contractor for permit-pulling and inspection coordination
- 6
Open trade accounts with electrical supply houses (Graybar, Rexel, Wesco) in Wisconsin for contractor pricing

Get registered as a Wisconsin licensed contractor with the Contractor State License Board or equivalent regulatory body

Build relationships with local general contractors and property managers — subcontract work is the fastest path to steady revenue for new electrical businesses
