ETF deemed disposal in Ireland: the 8-year rule for IBKR
Updated: 21/10/2026
How Ireland's 8-year deemed disposal taxes ETFs you never sold, the 41% and 38% rates, a worked example and how to report it from your IBKR account.
The deemed disposal rule means that eight years after you buy units in an EU-domiciled ETF, you are treated as having sold them and bought them straight back at market value. Exit tax is due on the growth — 41% for anniversaries in 2025 and 38% from 1 January 2026 — even though nothing was sold, and the tax is credited later when you really do sell.
Which ETFs are caught
The rule applies to funds treated as investment undertakings: funds domiciled in Ireland, in another EU or EEA state, or in an OECD country with a tax treaty with Ireland, that are regulated much like Irish funds. In practice that covers the UCITS ETFs Irish IBKR clients usually buy, with ISINs starting IE or LU.
It does not apply to:
- Individual shares, which stay under Capital Gains Tax.
- Investment trusts and other listed companies, which are shares, not funds.
- Funds held inside a pension, such as a PRSA or an occupational scheme.
US-domiciled ETFs are a grey area and their treatment depends on the fund, so check the specific product before assuming either regime. Most retail investors in the EU cannot buy them at IBKR anyway, because they lack the key information document EU rules require.
How the 8-year clock works
Every purchase is a separate lot with its own anniversary. Someone who has bought the same ETF every month for years will eventually face a deemed disposal every month.
On each anniversary the lot is valued at its market price that day. The gain is that value minus what the lot cost in euro, and exit tax is charged on it. A lot that has fallen in value produces no tax, but the loss cannot be used against anything else. While you keep holding, the cycle repeats every eight years.
Accumulating ETFs pay out nothing, so the deemed disposal is often the first time they are taxed. Distributing ETFs are also taxed at the exit-tax rate on each distribution, every year.
A worked example
Ciarán invested €10,000 in an Irish-domiciled accumulating ETF in June 2017. In June 2025 the units were worth €18,500.
- Deemed gain: €18,500 − €10,000 = €8,500
- Exit tax at 41% (a 2025 event): €8,500 × 0.41 = €3,485
He keeps holding and sells everything in 2027 for €21,000. The gain on the sale is measured from his original cost: €21,000 − €10,000 = €11,000. At 38% that is €4,180. The €3,485 already paid is credited, so only €695 more is due — assuming today's rates still apply in 2027.
Reporting a deemed disposal, step by step
- Download Activity statements from IBKR going back to your oldest ETF purchase; Performance & Reports, then Statements, lets you run earlier years.
- List every ETF buy: date, ISIN, number of units and euro cost including commission.
- Mark the lots whose eighth anniversary fell in 2025.
- Find the closing price on each anniversary and work out the market value of each lot.
- Add up the positive gains and enter them in the offshore funds part of the foreign income section on your 2025 Form 11.
- Pay the exit tax with your Form 11 balance by 31 October 2026, or the later ROS date, and keep a record of tax paid per lot for the credit on a future sale.
Neither IBKR nor the fund deducts this tax for ETFs held through a broker, so it is entirely up to you.
Planning around the rule
Selling before the eighth anniversary does not avoid anything: a real sale is taxed at the same rate. What you can do is plan:
- Keep cash aside in the years when large lots reach their anniversary.
- Track lots individually rather than relying on your average position.
- Compare the after-tax picture of ETFs with direct shares, which get the €1,270 exemption and loss relief but carry more single-company risk.
- Ask whether part of your investing belongs inside a pension, where the rule does not apply. A qualified adviser can help weigh that.
Common mistakes
- Believing accumulating ETFs are untaxed until you sell.
- Using the date the position was first opened for every lot.
- Claiming the €1,270 CGT exemption against ETF gains.
- Offsetting ETF losses against gains on shares.
- Applying the wrong rate: the date of the event decides it, so 2025 anniversaries are taxed at 41% and 2026 ones at 38%.
An anniversary you missed years ago does not disappear — it waits, with daily interest attached. Upload your IBKR statements to Brokers.tax to see which ETF holdings fall under the exit-tax regime and what each gain looks like at the current rate, so nothing catches you out at the next Form 11.
