The increased speed and mobility of business activities and cross-border transactions resulting from internet usage has particular implications for applying transfer pricing methods and for taxing business profits. This book presents a two-part look at existing OECD positions on these issues. Part I of this edition analyses e-commerce transfer pricing in the context of four business models: automated electronic transactions; online auctions for customer-to-customer and business-to-business sales; subsidiary-to-parent web hosting arrangements; and computerised transactions for airline reservations. The OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations provide guidance on the application of the arm’s length.
