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.

Next Steps to Launch Your General Contracting Business

Form your LLC or corporation in Wisconsin — general contractors carry significant liability for subcontractor work and project defects (filing fee: $130)
- 2
Obtain your Wisconsin general contractor license — requires experience documentation, exam, and financial statements in most states
- 3
Obtain a contractor surety bond and general liability insurance — bond requirements vary by state and the GL premium is typically a meaningful four-figure annual cost; both are required for most permits and contracts
- 4
Complete OSHA 30-Hour Construction Safety training — required by most commercial project owners and insurance carriers
- 5
Register with Wisconsin Contractor State License Board or equivalent regulatory agency and maintain license with required continuing education
- 6
Build a subcontractor network: licensed plumbers, electricians, HVAC techs, and framers — GCs depend on reliable subs for project quality
- 7
Create a construction contract template using AIA or AGC contract forms covering scope, payment schedule, change orders, and warranty
- 8
Get workers' compensation insurance before hiring any employees or subcontractors — Wisconsin requires WC for all construction workers
