Third‐party reporting and cross‐border tax planning
研究了欧盟2018年DAC6指令要求第三方中介报告跨境税务安排的效果，发现受影响企业减少了利润转移并提高了实际税率，对税务政策制定者和跨国公司有参考价值。
Abstract In 2018, the European Union (EU) introduced a new mandatory reporting requirement for a wide range of cross‐border tax arrangements (EU Directive 2018/822, also known as DAC6). Unlike prior corporate transparency initiatives, which put the reporting responsibility primarily on the taxpayers, this directive puts the initial reporting responsibility on the third‐party intermediaries who are involved in the reportable arrangement at any stage during the planning and execution process. We exploit the adoption of DAC6 in the EU to examine the effectiveness of third‐party reporting in curbing cross‐border tax planning by multinationals. Using a difference‐in‐differences research design, we find that affected firms reduce income shifting and report higher effective tax rates in the post‐adoption period. The reduction in income shifting is stronger for affiliates operating in countries without legal professional privilege extensions and in countries where noncompliance penalties are higher. Our results highlight the importance of strong third‐party reporting requirements in constraining cross‐border tax planning.
