Transfer Pricing in the US is the best and most up-to-date summary of transfer pricing practices available today. In the twenty-first century economy, where multinational enterprises are dominant players, transfer pricing—pricing goods and services transferred within a multinational or transnational company in order to reduce tax burdens and maximize profits—has become the new game. Although transfer pricing is not per se illegal or abusive, in practice its manipulation facilitates large-scale tax evasion and has thus become a major concern of revenue authorities worldwide. This concise but comprehensive analysis focuses on how the United States (US), home of most of the multinationals engaging in abundant and complex transfer pricing arrangements, approaches the task of combating the abusive transfer pricing machinery.
