Holding in Ireland: 12.5%, participation exemption and Pillar Two

Concept

Ireland is one of the most widely used holding jurisdictions in the EU. The combination of a 12.5% rate on trading profits, a network of 75 tax treaties in force and English-language common law makes it a convenient base for the parent company of an international group. An important caveat concerns passive and non-trading income: it is taxed at 25%, so holding only passive assets through Ireland is not efficient — the advantage comes through where the company has its own trading or operating function. How Ireland compares with the other options can be seen in the overview of holding structures.

History

Low corporate tax drew the European headquarters of American technology and pharmaceutical groups to Ireland over several decades. The famous 'Double Irish' scheme, through which profit escaped offshore, was wound down under pressure from the OECD and the EU — closed to new structures from 2015 and finally by 2020. After that the country kept the nominal 12.5% for most companies and adopted the global minimum tax (Pillar Two) for the largest groups, staying within the logic of the BEPS consensus.

Pillar Two

Since 1 January 2024 Ireland has applied the Pillar Two rules: the Income Inclusion Rule and a Qualified Domestic Top-up Tax (QDTT), with the Undertaxed Profits Rule added from 2025. Groups with consolidated revenue of €750 million or more top up to an effective 15%; the nominal rate stays at 12.5%, and the QDTT collects the difference domestically rather than surrendering it to the budgets of other jurisdictions.

The first compliance cycle has already run. For groups with a financial year closed on 31 December 2024, registration in the Revenue system fell due on 31 December 2025, but in December 2025 Revenue extended the deadline to 28 February 2026 (eBrief 244/25); the penalty for missing it is €10,000 per company. The first filings — the top-up tax information return and the tax return with payment of the top-up for the same year — were due by 30 June 2026. For groups entering the perimeter later the general rule applies: registration within 12 months of the end of the first fiscal year in scope. A simplified effective-rate test applies for the transition period: a threshold of 15% for 2024, 16% for 2025 and 17% for 2026.

Holding exemptions

An Irish holding company leans on two exemptions. The first is on capital gains (the substantial shareholding exemption, section 626B): the gain on the sale of a stake is exempt if the parent held at least 5% for 12 months within the previous two years, and the subsidiary carries on a trade and is resident in the EU or a treaty country. The second appeared recently: from 1 January 2025 a participation exemption for foreign dividends applies — distributions from EEA and treaty-partner countries on a stake of 5% or more can be exempted from Irish tax. Finance Act 2025 widened the regime for distributions made on or after 1 January 2026: the look-back period over which the subsidiary's residence in a qualifying jurisdiction is tested was cut from five years to three, and the exemption now also reaches non-treaty countries where a non-refundable withholding tax has been levied at source.

Treaties and intellectual property

Ireland's strength is its treaty network: 78 agreements signed and 75 in force, covering every major economy and cutting withholding tax on inbound flows; they have to be used with an eye on the principal purpose test and the MLI. For businesses built on intellectual property there are separate incentives — the Knowledge Development Box regime and the R&D tax credit — which is historically what drew technology groups to the country.

Substance: real presence

The preferential rate and the exemptions only work where there is a real presence. A company incorporated in Ireland on or after 1 January 2015 is treated as Irish tax resident by virtue of incorporation alone (section 23A TCA 1997), unless a double taxation agreement treats it as resident elsewhere; central management and control decides the question for companies incorporated abroad. The board is therefore still convened in Ireland and the key decisions taken locally: that is what protects residence in a treaty dispute and evidences presence. For trading companies there is the added test of an office and staff: access to the 12.5% rate is secured by employees and functions actually performed, whereas a registered address alone guarantees nothing. How presence is evidenced and where the line runs with nominal holding is discussed in the materials on economic substance and on beneficial ownership.

Repatriation: upstream payments and withholding tax

Dividends leaving Ireland to non-residents are, as a general rule, subject to withholding tax at 25%. In practice it is most often lifted: the exemption applies to recipients from the EU and treaty countries, and to companies controlled by residents of such jurisdictions. Since 1 April 2024 outbound payment rules have applied — they block the payment of dividends, interest and royalties to related structures in tax-free jurisdictions and countries on the EU blacklist. So the upstream payment route and the financing of the Irish company are planned in advance.

Limitations and anti-avoidance

Tax planning in Ireland runs within the tight frame of European law. The deduction of intra-group interest is limited by the ATAD rules: net interest expense of no more than 30% of EBITDA, with a €3 million exemption threshold per year. The profit of low-taxed subsidiaries may be attributed to the Irish parent under the CFC rules, and hybrid mismatches are closed by the anti-hybrid provisions of the same directive. On top sit the general anti-avoidance rule (GAAR) and the principal purpose test in the tax treaties: relief is withdrawn if a structure has no business purpose beyond the tax advantage.

The Apple case and the evolution of the regime

The EU's attitude to Irish tax rulings is best shown by the Apple case. In September 2024 the Court of Justice of the EU handed down its final judgment: the individual tax rulings of 1991–2014 were held to be unlawful state aid, and Ireland is required to recover more than €13 billion from the company. The era of one-off arrangements with the administration is over — the rate and the exemptions are secured by law and by real activity. Ireland has remained an attractive holding base for groups with a genuine presence and operations; this evolution cuts off paper structures. How the very notion of a 'tax haven' has changed is shown by the shift to tax transparency.

When an Irish holding is justified

In practice Ireland is chosen in several typical scenarios: the EMEA headquarters of an American group, an intermediate sub-holding above operating companies in Europe, a licensor company for IP with its own team, or a platform for a listing or for raising debt finance under common law. In each of them the 12.5% on trading profits, the exemptions on dividends and capital gains, and direct access to the EU directives and the treaty network work together.

The flip side shows on purely passive asset holding: such income is taxed at 25%, and for a large group a Pillar Two top-up is added on top. For tasks like that, people look more at the design of dividend flows or at neighbouring EU jurisdictions, to which we turn below.

Ireland against its EU neighbours

On the basic capabilities Ireland is close to the other EU holding jurisdictions. A participation exemption for dividends and capital gains exists in the Netherlands and in Luxembourg too; Ireland's advantage is the 12.5% rate on trading profits, English-language common law and its convenience for groups with real operating activity and access to the US market.

Cyprus and Malta come into the comparison too — with attractive regimes for the beneficiaries themselves as individuals and a light burden at the holding level. The choice between these jurisdictions and Ireland is usually decided by the actual location of the group's people and functions; the rate is secondary, because the resilience of the construction rests on substance anyway.
