🇮🇪 Corporate Tax in Ireland

Headline rate: 12.5% (trading) / 25% (non-trading)

Private Company Limited by Shares (Ltd)

Trading profits are taxed at 12.5%, one of the lowest rates in the OECD. Non-trading (passive) income such as investment income, rental income, and certain foreign-source income is taxed at 25%. A Knowledge Development Box (KDB) offers an effective rate of 6.25% on qualifying IP profits. Ireland has no withholding tax on dividends paid to EU parent companies under the EU Parent-Subsidiary Directive, and an extensive treaty network reduces withholding taxes on outbound payments. The R&D tax credit provides a 25% credit on qualifying expenditure. From 2024, a 15% global minimum top-up tax applies to companies within groups with consolidated revenue exceeding €750 million (Pillar Two).

Designated Activity Company (DAC)

Taxed identically to an Ltd company. Trading income is subject to the 12.5% corporation tax rate and non-trading income to the 25% rate. DACs used as SPVs in securitisation transactions can qualify for Section 110 treatment, where taxable profits may be reduced to near zero through the deductibility of profit-participating notes. The same R&D tax credit (25%), Knowledge Development Box (6.25% effective rate), and EU directive benefits apply. DACs in regulated financial services may also benefit from specific reliefs for qualifying fund management and aircraft leasing activities.
