How the 8-Year Deemed Disposal Rule Works
Ireland taxes most Irish and EU-domiciled investment funds and ETFs under a separate exit-tax regime, not under ordinary Capital Gains Tax. Two features make it unusual, and both catch investors out.
First, the tax rate is 38% on gains — higher than the 33% CGT rate that applies to individual shares. (The rate was 41% up to 31 December 2025; Finance Act 2025 cut it to 38% with effect from 1 January 2026. Deemed disposals that fell due before 2026 were taxed at the old 41% rate.) Second, you don't get to wait until you sell. Under Section 747E of the Taxes Consolidation Act 1997, you are treated as if you sold your holding on its eighth anniversary, and every eight years after that, even though you still own it. This is the "deemed disposal", and tax falls due on the unrealised gain at each of those points.
The 8-year clock starts on the purchase date of each lot you buy. When a deemed disposal happens, you pay 38% on the growth since you bought (or since the previous deemed disposal), and the clock resets to measure the next eight years from that new value. Because tax paid at a deemed disposal is credited against the tax due when you actually sell, the same gain is never taxed twice — but the timing means you hand cash to Revenue years before you cash out, losing the compounding on that money.
The Core Formula
Tax at each deemed disposal = 38% × (fund value on the 8-year date − value at purchase or previous deemed disposal).
At final sale = 38% × total gain, less the tax you already paid at deemed disposals.
Worked Example: €10,000 in a Global ETF
Say you invest €10,000 in an Irish-domiciled world ETF (for example an IE-prefixed accumulating fund) growing at 7% a year, and you hold for 24 years.
- Year 8 deemed disposal: the fund is worth about €17,182. Gain since purchase = €7,182. Tax at 38% = €2,729, payable now even though you haven't sold.
- Year 16 deemed disposal: the fund is worth about €29,522. Gain since the last event = €12,340. Tax at 38% = €4,689.
- Year 24, you finally sell: the fund is worth about €50,724. Gain since the last event = €21,202. Tax at 38% = €8,057.
Total tax over the life of the holding is about €15,475 — which is exactly 38% of your total €40,724 gain. Nothing is double-counted, but you paid over €7,400 of it at years 8 and 16, long before you saw a cent of proceeds. Had the same gain been on individual shares taxed at 33% (with the €1,270 exemption), the bill would have been about €13,020, and none of it due until you sold.
Why the Timing Matters
Two funds with identical 38% headline tax can leave you with very different net wealth depending on when the tax is paid. Paying at year 8 removes money that would otherwise have compounded for 16 more years. Model your own numbers in the calculator above to see the drag.
Deemed Disposal vs. Capital Gains Tax
Whether your investment falls under the 38% exit-tax regime or the 33% CGT regime depends on what you hold, not which broker you use. Broadly, Irish and EU-domiciled ETFs and funds sit in the exit-tax regime; individual shares (including single Irish or US company stocks) sit in the CGT regime.
| Feature | EU-domiciled ETF / Fund | Individual Shares |
|---|---|---|
| Tax rate on gains | 38% exit tax | 33% CGT |
| When tax is due | Every 8 years (deemed disposal) and on sale | Only on actual sale |
| €1,270 annual exemption | Does not apply | Applies each year |
| Loss relief | No — losses can't offset other gains | Yes — losses offset gains |
| Cost basis method | FIFO, per fund | FIFO, with 4-week anti-avoidance rule |
| Reporting | Form 11 / exit-tax self-assessment | CGT return (Form CG1 / Form 11) |
Note that US-domiciled ETFs (with an ISIN starting "US") are treated differently again and can fall under normal CGT rather than the 38% exit tax — but they are often hard for Irish retail investors to buy under EU rules. This calculator models the common Irish/EU-domiciled case; always confirm the domicile of your specific fund.
Common Pitfalls
1. Accumulating ETFs still trigger deemed disposal
Many Irish investors choose accumulating ETFs to avoid handling dividends. But rolling income up inside the fund does not defer the exit tax — the 8-year deemed disposal still lands, and you may owe 38% on gains you never received as cash. Make sure you have liquidity to pay it.
2. No loss relief
If one fund gains and another loses, you cannot net them off. You pay 38% on the winner and get nothing back for the loser (within the fund regime). This asymmetry can push your effective tax above 38% across a volatile portfolio.
3. Multiple purchase lots, multiple clocks
Every purchase starts its own 8-year clock. If you invest monthly, you can have dozens of separate deemed-disposal dates for a single ticker, each taxed on its own gain under FIFO. Tracking this by hand in a spreadsheet is where most people slip up.
The Deadline Is Yours to Track
Revenue does not send you a reminder when a deemed disposal falls due. Missing it means interest and penalties on top of the 38%. If you hold several funds bought on different dates, an automated tracker is far safer than a calendar note.
What Records to Keep
To calculate exit tax correctly — and to claim the credit at final sale — keep the following for every fund you own:
- Purchase date and cost of each lot (the start of each 8-year clock).
- Number of units bought and sold, to apply FIFO correctly.
- Fund value on each 8-year anniversary, plus the tax paid at that deemed disposal.
- Fund domicile / ISIN, to confirm the 38% regime applies (IE and LU prefixes are the common ones).
- Distributions received, which are taxed at 38% as they arise.
