What you’ll need

The Corpus intake collects this information to prepare the filing. Some questions are asked only when they apply — for example, the management question is asked only when the company has more than one owner.

  • What do you want to name the company?
  • In a sentence, what will the business actually do?
  • Where should official mail go — street, city, state, ZIP?
  • What email should we use for this order?
  • Which industry code fits this business?
  • Besides you, will anyone else have authority to make decisions for the business?
  • Who owns this company?

Wisconsin asks nothing beyond the standard questions.
