How Countries Should Share Tax Information

Abstract

Abstract This chapter looks at exchange of information (EOI) policies, proposing several ways to make EOI policies fairer and more efficient, so as to maximize their potential to reduce illicit financial flows and curb abusive tax practices that undermine human rights. While there appears increasing policy and academic support for EOI initiatives that promote global financial transparency, the current international tax regime, with its high transaction costs for taxpayers and tax authorities, does not seem particularly amenable to producing optimal outcomes. The chapter then emphasizes how, to promote enforceability, the ideal EOI system delivers high-quality tax information while providing needed legal protections for taxpayer privacy. The exchange and usage of high-quality tax information would reduce transaction costs for tax authorities as they could more readily identify taxpayers engaged in offshore tax evasion and aggressive international tax planning.
