Why one product can be taxed four different ways
Ireland did not design a single system for investment funds. Irish funds and life assurance products sit in the gross roll-up regime, where nothing is charged while you hold and a chargeable event settles at 38% exit tax. Offshore funds were brought in separately and split by where they are established and what they legally are, which produces four more outcomes: 38% again where the fund is equivalent to an Irish one, 33% Capital Gains Tax where it is not, a special 40% rate for a certified distributing fund outside the treaty network, and marginal income tax with USC and PRSI for a non-distributing one. The Department of Finance's own retail investment roadmap calls the result overly complex.
Life assurance splits the same way and less visibly. A policy written by an insurer established elsewhere in the EU, the EEA or an OECD treaty state carries the same 38% and none of the convenience: the insurer cannot operate Irish tax, taking the policy out is itself a filing obligation, and the eight-year clock runs from the policy's inception. A policy from outside that network falls out of those rules entirely, and no published rate replaces the 38%. Cutting across all of it is one anti-avoidance rule worth knowing about before you meet it: where the investor can influence which assets the fund or policy holds, the charge is 60% rather than 38%, and 80% on a gain that is not correctly returned. Finance Act 2025 cut exit tax and deliberately left those two alone.
That was survivable while a shortcut existed, and until 2022 one did: Revenue confirmed that ETFs domiciled in the USA, the EEA or an OECD treaty state followed the treatment that applies to shares generally. It withdrew that with effect from 1 January 2022. A treatment somebody was told about before then may no longer be the right one, and where such a fund is now equivalent to an Irish one its eight-year clock is counted from 2022 rather than from the year it was bought.
