Taxes on Corporate Income – Pillar Two – Ireland


Ireland has legislated for the Pillar Two rules with effect from:

  • 1st January 2024 for the Income Inclusion Rule and
  • 1st January 2025 for the Under Taxed Profits Rule


The Pillar Two rules provide that income of large groups is taxed at a minimum effective tax rate of 15% on a jurisdictional basis.


These rules apply where the annual global turnover of the group exceeds €750m in two of the previous four fiscal years.


Ireland signed up to the OECD Two Pillar agreement in October 2021.


The new minimum tax rate, which is effective from the 1st of January 2024, sees an increase from the previous corporate tax rate of 12.5% to 15%, for certain large companies.


Ireland will continue to apply the 12½% corporation tax rate for businesses outside the scope of the agreement, i.e. businesses with revenues of less than €750 million.


There are special rules for intermediate parent entities and partially owned parent entities as well as certain exclusions.


It is understood that Revenue estimates approximately 1,600 multinational entity groups with a presence in Ireland will come in scope of Pillar 2.


In addition, the EU Minimum Tax Directive (2022/2523) provides the option for Member States to implement a Qualified Domestic Top-up Tax (QDMTT).


A domestic top-up tax, introduced in Ireland from 1st January 2024, allows the Irish Exchequer to collect any top-up tax due from domestic entities before the application of IIR or UTPR top up tax.


The QDTT paid in Ireland is creditable against any IIR or UTPR top up tax liability arising elsewhere within the group.


It is important to keep in mind that IIR or UTPR top up tax may not apply in relation to domestic entities in circumstances where the domestic top-up tax has been granted Safe Harbour status by the OECD.


As there will be separate pay and file obligations and standalone returns for IIR, UTPR and QDTT, Revenue guidance material will be provided, in due course, in relation to all administrative requirements.
