Bu iş birliklerinin en önemli aracı ise bilgi değişimidir. AB, ABD ve OECD öncülüğünde yürütülen çalışmalar sonucu günümüzde çok sayıda ülke bilgi değişimi anlaşmalarına katılmaktadır. Bu bağlamda çalışmanın amacı vergi idareleri arasındaki bilgi değişiminin uluslararası vergi kayıp ve kaçağının önlenmesindeki rolünün tespitidir. Literatürde bu konuda yapılmış çalışmalar analiz edilmekte çeşitli sonuç ve öneriler sunulmaktadır. Buna göre ülkeler arasında iki taraflı ve talep üzerine bilgi değişiminin vergi kayıp ve kaçaklarını yeterince engelleyemediği görülmektedir. Bunun yerine günümüzde daha etkin olduğu görülen çok taraflı otomatik bilgi değişimi tercih edilmektedir. Ayrıca vergi idareleri arasındaki bilgi değişiminin mükelleflerin vergiye gönüllü uyumunu, idareye olan güveni ve vergi gelirlerini arttırabileceği sonucuna da varılmaktadır. Bununla birlikte kapsam dışında olan ülkelerin (özellikle ABD’nin) CRS’ye dahil olması, otomatik bilgi değişiminden kaçınılmasını sağlayabilecek uygulamalara karşı (yatırım yoluyla vatandaşlık alınması vb.) düzenlemelere gidilmesi önerilmektedir. KW - Bilgi Değişimi KW - Vergi Kaçakçılığı KW - Vergi Cennetleri KW - Banka Gizliliği N2 - After the 2008 Financial Crisis, the development of cooperation between tax administrations to prevent tax losses and evasion has become an important policy objective in the international arena. The most important tool of this cooperation is the exchange of information. As a result of the efforts led by the EU, the US and the OECD, many countries are now participating in information exchange agreements. In this context, the aim of this study is to determine the role of information exchange between tax administrations in preventing international tax losses and evasion. The studies in the literature on this subject are analyzed and various results and suggestions are presented. Accordingly, it is seen that bilateral and on-demand exchange of information between countries cannot sufficiently prevent tax losses and evasion. Instead, multilateral automatic information exchange, which is seen to be more effective today, is preferred. It is also concluded that information exchange between tax administrations can increase taxpayers' voluntary tax compliance, trust in the administration and tax revenues. In addition, it is suggested that countries that are out of scope (especially the US) should be included in the CRS and that regulations should be introduced against practices that may avoid automatic exchange of information (such as obtaining citizenship through investment.
