Abstract: As a new-rising financing measure,asset securitization has soon become fashionable globally in a short period of 20 years owing to its particular characteristics and superiority. China has also made a stride in the pilot securitization of credit assets.However, asset securitization is not an isolated process, which requires a set of systems, including law, accounting and tax systems etc. which suit it well. The tax factor holds the balance in the process of Asset Securitization and directly affects its efficiency of financing. Tax matters in the transnational asset securitization are especially of its own feature. The transactional method of transnational asset securitization is first looked through in this paper, and then the concerning international double taxation issues are discussed, including the choice of location of SPV, Permanent Establishment and double source income, etc. Because
