Corporations – Data Services

The Department of Financial Institutions is the office of record for domestic and foreign business and nonprofit corporations, cooperatives, limited partnerships, limited liability companies, and limited liability partnerships. We are not, however, a registry for businesses in the state of Wisconsin. The many sole proprietors and general partnerships doing businesses in the state may not be registered with any state agency. That being said, we offer elements of our database information for purchase on an incidental or recurring basis.

The two datasets we offer are the complete corporate database delivered via a fixed-length ASCII file and stored on a CD for $40/disc, and a monthly record of entities formed or registered in the previous month delivered via .txt file and .xlsx spreadsheet by e-mail for $5/month. The information in these files includes:

  • Legal entity name
  • Registered agent/office address
  • Entity type
  • Date of formation/registration
  • Current status
  • Numeric indicator for most-recent annual report filing

We do not have entity "owners" or LLC members on record with our department. Additionally, officers/directors of corporations are provided to us on the annual report, but that information is not included in this database.

To request the complete database via CD or the monthly new formations e-mail, please submit Form SP-51 (Commercial bulk Data Request) to:
