What changed

Ireland taxes trading income at 12.5% and non-trading income at 25%. It legislated the Pillar Two rules with effect from 1 January 2024 for the Income Inclusion Rule and the Qualified Domestic Top-up Tax, and from 1 January 2025 for the Undertaxed Profits Rule. In-scope groups, with consolidated revenue of EUR 750 million or more in at least two of the four preceding years, pay at least a 15% effective rate in Ireland.

Who is affected

Large multinational groups with Irish operations; companies comparing Ireland with the UK or other EU locations for an EU base.

Why it matters

For most companies the 12.5% rate remains, so the gap with the UK's 25% main rate is large. For large groups the effective floor is 15%, and the choice rests more on EU market access, talent and substance. The UK vs Ireland Decision Map sets these side by side.

What to examine next

Check which rate applies to each income stream (trading or non-trading).
Confirm whether the group is in scope of Pillar Two.
