  • Publication number: 20050209939
    Abstract: An automatic international tax planning system is described. In a distributed client server computer network, a transaction analyzer and tax planning system is employed to define a transaction between a company in a first country and a company in a second country. The system first identifies the business entities within a multinational company and the tax paying status for the business entities with respect to an international transaction. The system next identifies any intercompany transactions that can be created to reduce taxes paid by the company for a transaction involving a second company in a receiving country. A user interface takes input in the form of data and parameters from a user, and provides a selection of possible strategies regarding the routing and/or structuring of the transaction. The user selects one or more strategies to evaluate and engages a tax calculation engine to calculate the tax cost associated with the selected strategy.
