An initiative is needed to break the logjam in the international negotiations to reform taxation of multinational enterprises (MNEs). The explosion of profit shifting observed since the 1990s has resulted in hundreds of billions of dollars of tax revenues being lost around the world each year – but reform efforts have thus far failed to deliver measurable progress on the primary agreed goal of better aligning MNEs' taxable profits with the location of their real economic activity. More recently, countries have committed also to ensure that MNEs’ global profits are subject to a minimum effective tax rate, but international agreement depends on designing an approach that can gain wide support. Our proposal for a minimum effective tax rate (METR) could be applied to MNEs by any countries that choose to do so, whether they are home to MNEs, host of MNEs, or both. The METR would be compatible with existing tax treaties, but being non-discriminatory it also complies with other international obligations and could be introduced unilaterally. Economic modelling shows the METR would deliver major revenue gains for participating countries, and adoption would also contribute to, rather than impede, momentum for a more comprehensive multilateral agreement.

终止公司滥用税收的实用建议：METR，跨国公司的最低有效税率

需要采取一项举措来打破国际谈判中的僵局，以改革跨国企业 (MNE) 的税收。自 1990 年代以来观察到的利润转移爆炸式增长已导致全球每年损失数千亿美元的税收收入——但改革努力迄今未能在更好地调整跨国企业应纳税的主要商定目标方面取得可衡量的进展利润与其实际经济活动的位置有关。最近，各国还承诺确保跨国公司的全球利润受到最低有效税率的约束，但国际协议取决于设计一种能够获得广泛支持的方法。我们关于最低有效税率 (METR) 的建议可以由任何选择这样做的国家/地区适用于跨国公司，无论它们是跨国公司的所在地，多国企业，或两者兼而有之。METR 将与现有的税收协定兼容，但它是非歧视性的，它也符合其他国际义务，并且可以单方面引入。经济模型显示，METR 将为参与国带来巨大的收入收益，采用也将有助于而不是阻碍更全面的多边协议的势头。
