Create an Operating Agreement
Wisconsin doesn't require you to file an operating agreement, but a written one protects your liability shield and sets the rules for running the business.

Register for State Taxes and Local Licenses
Register with the Wisconsin Department of Revenue for any state taxes that apply, such as sales tax if you sell taxable goods or services. Check with your city and county for local business licenses.
Set Up Business Finances
