If you're considering moving to Ireland, understanding the tax landscape is one of the most important steps in planning your relocation. Among the taxes that catch many newcomers off guard, expat capital gains tax in Ireland stands out as one of the most misunderstood — and potentially costly if you get it wrong.
Whether you're selling property back home, disposing of shares, or liquidating investments before or after your move, Ireland's Capital Gains Tax (CGT) rules will likely affect you. This Ireland expat tax guide walks you through everything you need to know about CGT for the 2025/2026 tax year, including rates, exemptions, residency implications, and how to avoid common pitfalls.
What Is Capital Gains Tax in Ireland?
Capital Gains Tax (CGT) is a tax charged on the profit (or "gain") you make when you sell, transfer, or otherwise dispose of an asset. In Ireland, CGT applies to a wide range of assets, including:
- Real estate (investment properties, land, holiday homes)
- Shares and securities (stocks, bonds, investment funds)
- Business assets (goodwill, intellectual property, plant and machinery)
- Foreign currency gains above a certain threshold
- Cryptocurrency (yes, Revenue treats crypto disposals as chargeable events)
The key word is gain — you're taxed on the difference between what you paid for the asset (the "base cost") and what you received when you disposed of it, after allowable deductions.
The 2025/2026 CGT Rate
For the 2025/2026 tax year, the standard CGT rate in Ireland is 33%. This is one of the higher rates in Europe and applies to most chargeable gains. A reduced rate of 40% applies in certain specific circumstances, such as gains from life assurance policies and investment undertakings where exit tax rules apply.
There is also an entrepreneur relief rate of 10% on qualifying gains up to a lifetime limit of €1 million, which can benefit expats who are selling a qualifying business or business assets.
Annual CGT Exemption
Every individual is entitled to an annual personal exemption of €1,270. This means the first €1,270 of your total chargeable gains in any tax year is tax-free. While modest, this exemption can offset small gains from share disposals or minor asset sales.
How Irish Tax Residency Affects Your CGT Liability
Your CGT obligations in Ireland are fundamentally determined by your tax residency status. This is where things get nuanced — and where many expats make costly mistakes.
Understanding Irish Tax Residency
Ireland defines tax residency based on the number of days you spend in the country:
- You are tax resident if you spend 183 days or more in Ireland during a tax year, OR
- You are tax resident if you spend 280 days or more in Ireland over two consecutive tax years (with at least 30 days in each year).
A "day" counts if you are present in Ireland at any time during that day.
CGT Rules Based on Residency Status
| Residency Status | What's Taxable? |
|---|---|
| Irish resident & domiciled | Worldwide gains on all assets, wherever located |
| Irish resident but not domiciled | Irish gains + foreign gains only if remitted to Ireland |
| Non-resident | Only gains on Irish-situated assets (primarily Irish real estate and certain Irish shares/assets) |
This distinction is critical for expats. If you're moving to Ireland but are not "domiciled" there (meaning Ireland is not your permanent home in a legal sense), you benefit from the remittance basis of taxation. Under this rule, foreign gains are only taxed if you bring the proceeds into Ireland.
The Remittance Basis: A Key Advantage for Expats
The remittance basis is one of Ireland's most attractive tax features for incoming expats. Here's how it works in practice:
Example: Sarah, a US citizen, moves to Ireland in 2025 and becomes tax resident. She sells shares in a US company for a gain of $80,000. If Sarah does not transfer (remit) any of those proceeds to an Irish bank account or use them to purchase assets in Ireland, she owes no Irish CGT on that gain — because she is resident but not domiciled.
However, if Sarah transfers even a portion of those funds to Ireland, the remitted amount becomes subject to the 33% CGT rate.
Important: The remittance basis does not apply to gains on Irish-situated assets. If Sarah sells Irish property or Irish-listed shares, she pays CGT regardless of whether she remits the proceeds.
CGT on Selling Your Home: The Principal Private Residence Relief
One of the most common questions from people moving to Ireland taxes-wise is: "Will I pay CGT on my home?"
Ireland offers Principal Private Residence (PPR) Relief, which exempts your main home from CGT — but the rules have important conditions.
Qualifying for PPR Relief
To qualify for full relief, the property must:
- Have been your only or main residence throughout the entire ownership period
- Have a plot size of no more than one acre (0.4047 hectares)
- Not have been used for business purposes at any point
Partial Relief Scenarios
If you used part of the property for business, rented it out for a period, or it wasn't your main home for part of the ownership, you'll receive partial PPR relief. The gain is apportioned based on the period of qualifying occupation versus total ownership.
Example: John bought a house in Dublin in 2015 for €300,000. He lived in it as his main home until 2020, then rented it out. He sells it in 2025 for €500,000. His total gain is €200,000. He owned the property for 10 years but only lived in it for 5 years (plus the last 12 months of ownership count as qualifying occupation by default). So approximately 6/10 of the gain is exempt, and 4/10 (€80,000) is subject to CGT at 33%.
Selling Your Foreign Home After Moving to Ireland
If you sell your home in your country of origin after becoming Irish tax resident, PPR relief may still apply if the property was your main residence. However, timing is key. If you've already established a new main residence in Ireland, the old property may no longer qualify for full PPR relief. Planning the sale before or shortly after your move can make a significant difference.
Double Taxation Agreements and Foreign Tax Credits
Ireland has an extensive network of Double Taxation Agreements (DTAs) with over 70 countries, including the United States, the United Kingdom, Canada, Australia, Germany, France, and most EU nations. These treaties are designed to ensure you don't pay tax on the same gain in two countries.
How DTAs Work for CGT
In most DTAs, the rules for capital gains follow a common pattern:
- Real estate gains are typically taxable in the country where the property is located
- Share gains are generally taxable only in the country of residence (with some exceptions for property-rich companies)
- Business asset gains follow specific treaty articles
If you pay CGT in another country on a gain that is also taxable in Ireland, you can usually claim a foreign tax credit to offset the Irish CGT liability, preventing double taxation.
Example: Maria, a Spanish national living in Ireland, sells an apartment in Madrid for a gain of €50,000. Spain taxes this gain at approximately 23%. Ireland also wants to tax the gain (because Maria is Irish resident and the gain has been remitted). Under the Ireland-Spain DTA, Maria can credit the Spanish tax paid against her Irish CGT bill. Since Spain's rate (23%) is lower than Ireland's (33%), Maria would pay the difference (approximately 10%) to Irish Revenue.

Key CGT Filing Deadlines and Payment Dates
Ireland's CGT payment and filing system is unique — and missing the deadlines can result in interest charges and penalties.
The Two-Period Payment System
Unlike income tax, CGT in Ireland is payable in two installments based on when the gain arises during the tax year:
| Disposal Period | Payment Deadline |
|---|---|
| 1 January – 30 November | 15 December of the same year |
| 1 December – 31 December | 31 January of the following year |
Annual Tax Return
Regardless of when you pay the CGT, you must file a Form 11 annual tax return by 31 October of the year following the tax year (or mid-November if filing online via Revenue's ROS system).
Common Deadline Mistakes Expats Make
- Assuming CGT is due when you file your tax return — No, the payment is due much earlier (December or January), while the return is filed the following October/November.
- Forgetting to file when you've made a loss — Even if you didn't make a gain, you should file to carry forward capital losses for offset against future gains.
- Not registering with Revenue — As a new arrival, you must register for tax with the Irish Revenue Commissioners. You'll need a PPS (Personal Public Service) number.
Practical Tips and Common Mistakes for Expats
Moving to Ireland involves significant tax planning. Here are the most frequent CGT-related pitfalls and how to avoid them:
1. Failing to Establish Your Base Cost
When you become Irish tax resident, the base cost of your foreign assets does not reset to their current market value. Your original purchase price (or acquisition cost) remains the base cost. If you've held assets for many years, the gain could be substantial. Gather documentation — purchase receipts, brokerage statements, conveyancing documents — before you move.
2. Ignoring the Temporary Non-Residence Rules
If you become Irish resident, leave Ireland for a short period (fewer than five complete tax years), and then return, you could be subject to CGT on gains made during your absence. These anti-avoidance provisions are designed to prevent people from briefly leaving Ireland to realize gains tax-free.
3. Overlooking the SARP and Other Reliefs
While primarily an income tax relief, the Special Assignee Relief Programme (SARP) is relevant for expats arriving in Ireland on employment assignments. Understanding how SARP interacts with your broader tax position — including CGT — is important for holistic planning. You can also explore your income tax obligations using our Ireland Income Tax Calculator.
4. Crypto and Digital Assets
Irish Revenue treats cryptocurrency disposals as chargeable events for CGT purposes. Swapping one cryptocurrency for another, using crypto to pay for goods, and selling crypto for fiat currency all trigger potential CGT liabilities. Many expats mistakenly assume crypto is unregulated for tax purposes — it is not.
5. Not Claiming Allowable Deductions
You can deduct certain costs when calculating your gain, including:
- Purchase costs (stamp duty, legal fees on acquisition)
- Enhancement expenditure (costs that increased the asset's value, such as renovations)
- Disposal costs (estate agent fees, legal fees on sale)
- Indexation relief (for assets acquired before 2003, the base cost can be adjusted for inflation)
Frequently Asked Questions
Do I pay CGT in Ireland on assets I owned before moving here?
Yes, if you dispose of those assets while Irish tax resident, you may owe CGT. For non-domiciled residents, foreign asset gains are only taxable if remitted to Ireland. Gains on Irish-situated assets are always taxable.
Is there a tax-free threshold for CGT in Ireland?
Yes. Each individual has an annual exemption of €1,270. Gains below this amount are not taxable.
Can I offset capital losses against gains?
Yes. Capital losses can be offset against gains in the same tax year. Unused losses can be carried forward indefinitely to offset future gains but cannot be carried back to previous years.
What happens if I sell my home abroad after moving to Ireland?
If the property was your principal private residence, PPR relief may apply. However, once you establish a new main residence in Ireland, the foreign property may lose its PPR status. Timing and planning are essential.
How does Ireland tax gains from US retirement accounts (401k, IRA)?
Distributions from US retirement accounts are generally treated as income rather than capital gains in Ireland and taxed under income tax rules. The Ireland-US Double Taxation Agreement provides specific rules. This is a complex area where professional advice is strongly recommended.
Conclusion: Plan Before You Move
Moving to Ireland is an exciting step, but the capital gains tax implications require careful planning — ideally before you arrive. Here are the key takeaways:
- Ireland's CGT rate is 33%, one of the highest in Europe, with a modest annual exemption of €1,270.
- Your tax residency and domicile status determine what's taxable — the remittance basis can be a significant advantage for non-domiciled expats.
- Timing asset disposals around your move date can save thousands in tax.
- Double taxation agreements protect against being taxed twice, but you must actively claim relief.
- Filing deadlines are strict — CGT is payable in December/January, not when you file your annual return.
- Document everything — base costs, enhancement expenditure, and foreign taxes paid.
