How the calculator works
- Each purchase (your lump sum and every monthly amount) grows at the rate you choose.
- Every 8 years after each purchase, exit tax is charged on its gain. The calculator sells units to pay it, so less is left to grow.
- When you sell, exit tax is charged on the rest of the gain, after credit for what you’ve already paid.
- Comparisons: the same investment if tax were only charged when you sell, and shares taxed by capital gains tax.
Example
€10,000 in an ETF for 20 years, growing 6% a year:
| Held as | Tax | You keep |
|---|---|---|
| ETF, with deemed disposal in years 8 and 16 | €6,724 | €22,487 |
| ETF, if tax were only charged on sale | €7,725 | €24,346 |
| Shares, 33% CGT on sale | €6,864 | €25,207 |
Deemed disposal costs about €1,859 here. You pay less tax in total, but you pay it earlier, so the money taken in years 8 and 16 can’t keep growing.
Exit tax and capital gains tax
| ETFs and funds (exit tax) | Shares (CGT) | |
|---|---|---|
| Rate | 38% in 2026, 35% announced for 2027 | 33% |
| Yearly exemption | None | €1,270 |
| Taxed before sale | Every 8 years (deemed disposal) | No |
| Losses | Can’t be used | Set against gains |
| Income | Taxed at the exit tax rate | Dividends taxed as income |
What this calculator doesn’t include
Distributions from funds that pay them out, funds domiciled outside the EU (taxed under different rules), and pensions, where investments grow without exit tax. Exit tax is the only tax on these gains: PRSI and USC don’t apply, even when you pay it through your own tax return.
