How does mandatory IFRS adoption affect tax planning decision? Evidence from tax avoidance distributions
研究发现强制采用IFRS对公司避税的影响取决于其初始避税水平，且这种影响在投资者保护更强的国家更显著，而税收执法强度会削弱或增强这一效应。
The extant literature has provided much evidence on the consequences of adopting the International Financial Reporting Standards (IFRS), but studies that pertain to taxes and the IFRS are rare. This study investigates whether IFRS adoption affects corporate tax avoidance and how the impact of IFRS varies with country-level institutions. We find that the effect of an IFRS mandate on corporate tax avoidance is conditional; that is, firms with a lower (higher) initial level of tax avoidance tend to be more (less) tax aggressive after IFRS adoption. In addition, this conditional impact is more pronounced in regimes with higher levels of investor protection. We also find that the strength of country-level tax enforcement might erode (bolster) the positive (negative) effects of IFRS adoption.
