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 all businesses in the state of Wisconsin. There are many sole proprietors and general partnerships doing business in the state and they 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.
Option 1: Complete corporate database delivered via ShareFile as a .txt file
Option 2: Monthly record of entities formed or registered in the previous month delivered via .txt file and .xlsx spreadsheet by email. 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
Please submit 
Form 51 to request Commercial Bulk Data
Data sales orders are processed on Tuesday's of each week.
Monthly record of entities formed are sent around the second Monday of each month.
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.
