Quick answer: Ireland has no succession treaty with Italy. Relief comes only from a unilateral credit, and a credit is worth exactly what the foreign tax was. Because Italy exempts family transfers up to €1 million per beneficiary, the Italian bill on a typical holiday home is nil, the Irish credit is nil, and CAT at 33% lands on everything above the €400,000 Irish threshold.
There is a category of cross-border tax problem that only appears when both countries behave reasonably. Italy taxes family inheritance lightly. Ireland taxes it heavily but gives credit for foreign tax paid. Put those two sensible rules together and an Irish family owning an Italian house arrives at the worst combination available: full Irish tax, no relief, and a common piece of Italian planning advice that achieves nothing.
Why does the missing treaty matter more than the tax rates?
Ireland maintains two treaties for capital acquisitions tax purposes. One is with the United Kingdom, the other with the United States. There is no equivalent with Italy, and none is in prospect.
Where no treaty exists, section 107 of the Capital Acquisitions Tax Consolidation Act provides unilateral relief: a credit against Irish CAT for tax paid abroad on the same property, limited to the lesser of the two charges. The mechanism is standard and it works well when the foreign country has actually taxed something.
Italy has not. The Italian imposta di successione applies at 4% to transfers to a spouse or child, but only on the value exceeding a franchigia of €1 million per beneficiary. A house worth €600,000 passing from an Irish parent to an Irish child sits entirely inside that allowance, so Italy charges nothing.
The credit is therefore nil, and Irish CAT applies to the full Italian value above the Irish threshold as though the property were in Cork.
| Step | Amount |
|---|---|
| Italian house valued at | €600,000 |
| Italian franchigia for a child | €1,000,000 |
| Italian succession tax due | €0 |
| Irish Group A threshold | €400,000 |
| Taxable in Ireland | €200,000 |
| Irish CAT at 33% | €66,000 |
| Unilateral credit available | €0 |
What does that mean for the planning most Irish owners are offered?
Italian advisers routinely present the franchigia as a planning asset, and for an Italian family it is one. For an Irish family it is a relief they cannot use, applied to a tax they were not going to pay.
The consequence is that Italian-side structuring aimed at the franchigia produces no Irish benefit at all. Splitting ownership between two children to use two allowances of €1 million each is sound Italian advice and changes nothing, because both children were already inside the Italian allowance and both are exposed to Irish CAT on their own share above their own €400,000.
What does work is Irish, and it is worth naming because the correct adviser for this problem sits in Dublin rather than in Perugia.
- Irish thresholds are lifetime and cumulative across the group, so an Italian house inherited after earlier gifts lands on a partly used allowance
- Section 72 life assurance can be arranged specifically to fund a CAT bill, which is the standard Irish answer to an illiquid asset
- The small gift exemption used annually over many years reduces the eventual estate without touching the Italian side
- Where the intention is to pass the house on during life, Italian bare ownership structures interact with Irish gift tax rather than avoiding it, and the Irish valuation rules govern
Which parts of the Irish position are actually comfortable?
Not everything is worse. Two things work in an Irish buyer’s favour and both are worth knowing before the file gets pessimistic.
Income is covered by a treaty. Ireland and Italy do have an income tax convention, so Italian rental income taxed first in Italy at 21% or 26% under the flat regime, or under ordinary IRPEF, carries a credit against the Irish charge on the same income. The cedolare secca guide explains the Italian election, and the point for an Irish reader is that this half of the picture behaves the way people expect the whole picture to behave.
Freedom of movement is intact. Irish citizens are EU citizens, so the reciprocity condition never arises and there is no stay limit at the property. An Irish owner can spend six months of the year in Italy without a visa question, subject to registering with the comune after 3 months of continuous presence, and the purchase sequence proceeds without any nationality step at all.
Capital gains on a sale follow the treaty as well. Italy exempts a private seller after 5 years under article 67 TUIR, Irish CGT applies at 33% on the gain, and the treaty governs which side charges what. The selling guide covers the Italian mechanics, and here too the credit machinery functions normally.
What does Italian succession law itself do to an Irish will?
Separately from tax, Italian civil law reserves a share of an estate for close family. The legittima gives the spouse and children a protected fraction that a will cannot freely override, which is unfamiliar to Irish testators used to broader testamentary freedom.
The EU Succession Regulation of 2012 provides the route out. A national of a member state may choose the law of their nationality to govern the whole of their succession, and an Irish owner who makes that choice expressly in their will brings the Italian house under Irish succession law. The choice has to be made; silence leaves the law of habitual residence governing, which for an Irish resident is Irish law anyway, but for an Irish citizen who has moved to Italy would be Italian law with its reserved shares.
This is a civil law question rather than a tax one, and the two interact only in the sense that the tax follows whoever actually inherits. Our inheritance guide sets out the Italian mechanics, including the succession declaration that must be filed in Italy within 12 months of death.
- Red flag: an Irish will drafted before the Italian purchase that says nothing about foreign immovable property
- The choice of law belongs in the will, and a separate Italian will covering only the Italian asset needs care to avoid revoking the Irish one
- Forced heirship affects who inherits, not how much Irish CAT they pay
Does Irish non-domiciled status change the rental picture?
For a substantial minority of people living in Ireland it changes it completely, and this is the largest planning point on the page after the succession problem.
Ireland taxes residents on worldwide income, but a resident who is not Irish-domiciled is taxed on foreign income on the remittance basis: the foreign income enters the Irish charge only to the extent it is brought into Ireland. An Italian rental profit left in an Italian account, spent on Italian running costs, or reinvested in the property is outside the Irish charge until it is remitted.
The distinction matters because domicile and residence are different tests. Domicile is broadly the country a person regards as their permanent home and is difficult to change, so a professional who moved to Dublin from abroad and intends eventually to leave may well be Irish-resident and foreign-domiciled for years.
Two cautions belong with it. Remittance is broader than a bank transfer: spending remitted funds in Ireland, or using the income to service an Irish debt, can constitute a remittance. And the treatment applies to income rather than to capital acquisitions tax, so it does nothing about the succession exposure set out above.
- The remittance basis is claimed on the Irish return, not applied automatically
- Keep Italian rental receipts in a separate Italian account if the intention is not to remit
- Domicile is a question of fact and intention, and Revenue examines it on the evidence rather than the assertion
What does Ireland not have to worry about that others do?
Currency, and it is worth stating plainly because half the complexity on the American and British pages in this cluster comes from it.
Ireland uses the euro. The purchase price, the mortgage if any, the rent, the Italian tax and the eventual sale proceeds are all denominated in the same currency as the buyer’s own tax return. There is no exchange gain on repaying an Italian loan, no translation of monthly rent at the rate on the date of receipt, and no possibility of a taxable profit arising from a currency movement on a property that broke even.
That removes an entire category of risk and an entire category of professional fee. It also makes an Italian mortgage a genuinely comparable product: an Irish buyer weighing an Italian mutuo against releasing equity at home is comparing two euro loans on their merits, where an American or British buyer doing the same is also taking a currency position.
| Exposure | Irish buyer | Non-euro buyer |
|---|---|---|
| Exchange gain on loan repayment | None | Possible taxable event |
| Annual translation of rent | Not required | Required at transaction rates |
| Currency risk on eventual sale | None | Real and unhedged |
- Insider tip: the absence of currency risk is a reason to consider the Italian mortgage rather than a home-equity release, since the debt and the asset are then in the same currency
- SEPA transfers to a notary account settle in euro without conversion cost
- The only rate to watch is interest, and Italian and Irish mortgage pricing move independently, so the cheaper loan is a genuine comparison rather than a bet on the currency
Which buyer scenarios does this change?
The retiring couple buying for their own use. The purchase is straightforward and the exposure is at the far end. The decision framework is about whether the house is intended to pass to children, because if it is, the CAT bill is foreseeable from the day of purchase and can be funded gradually rather than discovered at probate.
The family buying jointly with adult children. Buying with the children on the title from the outset is a gift at the time of purchase rather than an inheritance later, and it is assessed against the same lifetime thresholds. This is often better than doing nothing and it is never neutral, so it belongs with an Irish adviser before the compromesso rather than after the deed.
The buyer intending to let. The income treaty works, the credit works, and the Italian election is the main decision. This profile has the least Irish-specific complication, and the ordinary due diligence and tax comparison work applies unchanged.
The Irish citizen relocating to Italy. Everything on this page shifts. Irish CAT follows the beneficiary’s residence, so children who remain in Ireland stay exposed regardless of where the parent lives, while the parent’s own Italian residence brings Italian worldwide taxation and the succession law question into play at once.
Frequently Asked Questions
No. Ireland has exactly two treaties covering capital acquisitions tax, one with the United Kingdom and one with the United States. Italy is not among them. Relief on an Italian house passing to an Irish beneficiary therefore comes only from unilateral relief under section 107 of the Capital Acquisitions Tax Consolidation Act, which is a credit rather than an exemption.
Because a credit needs a foreign tax to credit. Italy applies a franchigia of €1 million per beneficiary on transfers to a child and charges 4% only above it, so most family transfers of an Italian holiday home produce an Italian bill of zero. Unilateral relief then gives the Irish beneficiary a credit of zero, and Irish CAT at 33% falls on the full value above the Irish threshold.
The Group A threshold for a child inheriting from a parent is €400,000, unchanged in Budget 2026, with Group B at €40,000 and Group C at €20,000. It is a lifetime threshold across all gifts and inheritances from that group, so an Italian property is rarely arriving into an empty allowance. A €600,000 Umbrian farmhouse to a single child who has received nothing else produces CAT of about €66,000.
Not for the charge. Irish CAT is charged on the beneficiary, and where the beneficiary is resident or ordinarily resident in Ireland the tax reaches worldwide property. The location changes the administration, not the liability: an Italian dichiarazione di successione has to be filed in Italy within 12 months, and the Irish return is separate and on a different timetable.
Yes, and the planning has to be Irish rather than Italian, which is the practical point of this page. Irish mechanisms such as the dwelling house exemption, small gift exemptions used over years, and section 72 life cover taken out to fund the eventual bill all still work. Italian mechanisms aimed at the franchigia do nothing, because the franchigia was never the binding constraint.
Italy taxes it first, at 21% on the first short-let unit or 26% beyond it under the flat regime, or under ordinary IRPEF. Ireland then taxes the same income as foreign rental income with a credit for the Italian tax under the Ireland-Italy income tax treaty, which does exist even though the succession one does not. Income and inheritance are governed by different instruments and it is a common mistake to assume one treaty covers both.
Neither. Ireland is an EU member state, so the reciprocity condition never arises and an Irish buyer has the same civil capacity as an Italian one. Irish citizens also have free movement, so the 90 days in any 180 limit that constrains British owners after Brexit does not apply. An Irish owner can spend as long at the property as they wish, subject to registering residence after 3 months.
Forced heirship. Italian law reserves a share of the estate for the spouse and children, and unlike Ireland's more flexible position, that reservation constrains what a will can do with Italian assets. The EU Succession Regulation lets a national of a member state choose the law of their nationality to govern the whole estate, which is the mechanism Irish owners use, and it has to be exercised in the will rather than assumed.
