Investment returns in Ireland are taxed in three main ways. Capital Gains Tax at 33% applies to direct shares, property, and cryptocurrency. Exit tax at 38% applies to investment funds and ETFs, with a deemed disposal rule every eight years. Deposit Interest Retention Tax at 33% applies to savings interest. Getting the structure wrong can cost you thousands over a lifetime of investing.
One point before we start: pensions have their own tax treatment and are by far the most tax-efficient way to invest in Ireland. If you haven’t maximised your pension contributions, that should come first. Everything in this guide applies to investments outside of pension wrappers.
Capital Gains Tax (CGT)
Capital Gains Tax is the tax you pay on profits from selling assets. The rate is 33% on the gain, and it applies to direct shares, investment property, cryptocurrency, collectibles, and certain other assets. Your principal private residence is exempt.
Every individual has an annual CGT exemption of €1,270. Married couples each have their own exemption, so a couple can realise €2,540 in gains annually without any CGT. This exemption resets each year and cannot be carried forward.
Example: You bought shares for €10,000 and sold them for €16,000. Your gain is €6,000. After deducting the €1,270 exemption, your taxable gain is €4,730. At 33%, you owe €1,561 in CGT.
CGT Payment Dates
CGT has two payment windows: gains from January to November are due by 15 December; gains in December are due by 31 January. This catches many people out. If you sell shares in March and make a gain, you need to pay the CGT by mid-December, not when you file your annual tax return.
Using Losses
One of the key advantages of the CGT regime is that losses can offset gains. If you sell one investment at a loss and another at a profit in the same year, you only pay CGT on the net gain. Unused losses can be carried forward indefinitely.
Exit Tax and Deemed Disposal
Exit tax applies to gains from investment funds, including most ETFs. The rate is 38% from 1 January 2026 (reduced from 41% in Budget 2026). It applies to Irish and EU-domiciled funds, unit trusts, OEICs, and ICAVs. Check the fund’s ISIN code: if it starts with IE, LU, FR, DE, or another EU country code, exit tax almost certainly applies.
How Deemed Disposal
Works
Every eight years from when you purchased fund units, Revenue treats you as if you sold and immediately repurchased them. You owe tax on any unrealised gains at that point, even though you haven’t actually sold anything.
Example:
You invest €20,000 in an ETF in January 2018. By January 2026, it has grown to €35,000. Under deemed disposal, you owe exit tax on the €15,000 gain. At 38%, that’s €5,700 due, and you need to find that cash from somewhere.
Why Exit Tax is Harsher Than CGT
Higher rate:
38% versus 33% for CGT
No annual exemption:
You pay from the first euro of gain
No loss relief:
Losses on funds cannot offset gains
Deposit Interest Retention Tax (DIRT)
DIRT is the tax on interest from savings accounts and fixed-term deposits. The rate is 33%, deducted at source by your bank. You may be exempt if you or your spouse are aged 65+ and your total income is below €18,000 (single) or €36,000 (couple).
DIRT is a final tax for most people. You don’t pay additional income tax or USC on deposit interest. However, if your unearned income exceeds €5,000 in a year, you may owe PRSI at 4% on the excess.
Dividend Tax
Dividends are taxed as income, not capital gains. They’re subject to income tax at your marginal rate (20% or 40%), plus USC and potentially PRSI. For higher-rate taxpayers, total tax on dividends can reach 51% or more.
Irish companies withhold Dividend Withholding Tax (DWT) at 25% before paying you. Foreign dividends may also have tax withheld at source. Ireland’s tax treaties allow credit for foreign tax paid. The high tax rate on dividends is one reason many Irish investors prefer accumulating funds over income-producing investments.

Tax-Efficient Strategies
Maximise your pension first
Tax relief at your marginal rate plus tax-free growth is unbeatable. If you pay 40% tax, every €100 contributed costs you just €60.
Use your CGT exemption each year
The €1,270 exemption is use-it-or-lose-it. Consider selling enough shares to use your exemption and immediately repurchasing. Couples can realise €2,540 annually without any CGT.
Time your disposals
If you have gains and losses in the same year, they offset. Use previous years’ losses against current gains before they get forgotten.
Consider direct shares vs funds
Direct shares benefit from lower 33% CGT, the annual exemption, and loss relief. Funds are simpler but come with 38% exit tax and deemed disposal.
Use spouse transfers
Transfers between spouses are generally exempt from CGT. If one spouse has unused losses or exemptions, transferring assets before sale can reduce the family’s tax bill.
Frequently Asked Questions
Are ETFs tax-efficient in Ireland?
Not particularly. Most ETFs are EU-domiciled and subject to 38% exit tax with deemed disposal. From a pure tax perspective, direct shares are often more efficient for long-term holdings outside a pension.
Can I offset losses from funds against gains on shares?
No. CGT losses can offset CGT gains (shares, property, crypto), but losses on investments subject to exit tax cannot offset any gains. The two systems don’t interact.
How is cryptocurrency taxed?
Revenue treats cryptocurrency as property, so disposals are subject to CGT at 33%. Importantly, exchanging one crypto for another is a disposal for tax purposes. You need to track the euro value at each exchange.
What's the most tax-efficient way to invest?
Pension first, without question. After that, use your CGT exemption each year, consider direct shares over funds for taxable accounts, and coordinate with your spouse to maximise reliefs.
What happens to investments when I die?
There’s no CGT on death (beneficiaries receive assets at market value), but Capital Acquisitions Tax may apply. CAT is 33% above the relevant threshold. For parent to child, the threshold is €400,000.
Do I pay tax on foreign shares?
Yes. If you’re Irish tax resident, you pay Irish CGT on gains from selling foreign shares. Dividends from foreign companies are taxed as income. Ireland’s tax treaties provide credit for foreign tax withheld.
Getting your investment tax right
