One embodiment of the present invention provides a system that automatically inserts account-data into a tax-form. During operation, the system receives account-data at a server from a data-provider. The system also receives a tax-form at the server from an application. Next, the system automatically analyzes the account-data to determine a data-map which maps the account-data to the tax-form without assistance from a user. Finally, the system inserts the account-data into the tax-form by applying the data-map to the account-data.
