On the back of the phenomenal tax inflows into the Irish Exchequer confirmed by the record breaking EUR96 billion recorded in the 2021 Annual Report of the Revenue Commissioners last month, Ireland’s corporate tax regime has undergone profound changes in the past several years, as a number of contributions in this month’s Roundable remind us. They include the proposed OECD BEPS changes, ATAD, the EU UNSHELL Directive and the DEBRA Directive. Tax measures are also found in other EU legislation such as the EU Whistleblower Directive and the EU Securitisation Regulation, along with other features addressed in recent Irish law, such as the updated Transfer Pricing legislation, enacted in Finance Act 2019.
