Investment Undertaking Tax Rate Change
Tax and Duty Manuals Part 27-04-01 (Offshore Funds: Taxation of Income and Gains from EU, EEA and OECD Member States) and Part 27-01a-02 (Investment Undertakings) have been updated in respect of Finance Act 2025 amendments which reduced the rate of tax for individuals from 41 percent to 38 percent.
The reduced rate applies from 1 January 2026 in respect of income and gains from Irish domiciled investment funds and equivalent offshore investment funds in other EU Member States, EEA States and OECD countries with which Ireland has a double taxation agreement.
