A method and system for determining business expenditures with vendors and automatically generating and submitting required forms whereby vendor identification data and/or contact information is obtained. Data representing current vendor reporting requirements and/or contact information for any associated reporting agency is obtained and stored along with data representing one or more associated reporting forms. Financial transaction data associated with a business is then obtained and analyzed using the current vendor reporting requirement data to identify/match one or more vendors used by the business that are subject to the reporting requirement. At least part of the identification data associated with subject vendors, and at least part of the financial transaction data associated with the business, is used to auto-fill one or more forms associated with the reporting requirement for each of the identified subject vendors and the auto-filled forms are then sent to the respective vendors, and/or the appropriate reporting agency automatically.
