We have provided the attached spreadsheet to make it convenient for you to find, filter, and sort the data fields. This also enables you to save the data into other formats if necessary.

The file is currently sorted by JSON Section (groups). 

The data required in the OwnersOrOfficers section varies by the type of business. Therefore, this section requires special attention as there are numerous conditional fields.

Types of business include Sole Proprietorship, Corporation, Government, Limited Liability Company, Partnership, or Not for Profit. 

The file attached lists the Data Definitions in the first tab.

Subsequent tabs outline the required fields for each type of business.

  • If the field is required, it will state Required.
  • If the field is not required, it will be blank.
  • If there is a specified value for the field, the value will appear in the field.
