Italian Inheritance Tax for Foreigners: 5 Steps to File

How the 2026 Separation of Gift and Inheritance Thresholds Changes Estate Planning for Non-Resident Heirs in Italy

ABSTRACT: Italy's succession tax rules changed fundamentally on 1 January 2026 following Legislative Decrees 139/2024 and 123/2025. For the first time, lifetime gifts no longer erode a surviving heir's inheritance allowance — a structural shift that opens genuine planning opportunities for international families. Foreign heirs who ignore two critical deadlines now face penalties of up to 120% of the tax due.

Imagine you are a beneficiary named in your Italian aunt's will. You live in Toronto, the estate includes an apartment in Verona and a brokerage account in Milan, and you have never dealt with Italian tax authorities in your life. The will was professionally drafted, you have a copy, and you are reasonably confident everything is in order. What you may not realise is that Italy's succession tax system underwent its most significant structural reform in a generation on 1 January 2026 — and the new rules contain at least two traps that regularly catch non-resident heirs before they have even consulted a lawyer / before they have sought legal advice.

What the 2026 Reform Actually Changed

The reform was delivered in two stages: Legislative Decree 139 of 18 September 2024 and Legislative Decree 123 of 14 August 2025. Together, they amended the core succession tax statute (Decreto Legislativo 346 of 31 October 1990, governing the imposta di successione e donazione, Italy's unified inheritance and gift tax) in three ways that matter to international families.

First, the coacervo successorio — the rule that required previous lifetime gifts to be aggregated with the inherited estate when calculating available thresholds — has been abolished. Before 1 January 2026, a parent who had already given a child €600,000 during their lifetime had effectively consumed most of the €1,000,000 per-heir inheritance allowance. That drag is now eliminated / That burden no longer applies. Each heir now starts with a fresh €1,000,000 threshold on death, regardless of what they received as gifts during the deceased's lifetime.

Second, gift thresholds and inheritance thresholds are now entirely independent allowances / treated as separate limits. A parent can transfer up to €1,000,000 to a child free of gift tax, and that child can subsequently inherit up to a further €1,000,000 free of succession tax. The planning implications for families with Italian assets and heirs living abroad are considerable.

Third, the reform introduced mandatory self-assessment. Once the dichiarazione di successione (inheritance declaration, Italy's equivalent of an estate return) has been filed, the heir must calculate and pay any succession tax due within 90 days. There is no longer a period of passive waiting for a tax-authority assessment. Miss the 90-day window and penalties apply automatically / penalties kick in automatically.

Do I Pay Inheritance Tax in Italy as a Non-Resident Heir?

The short answer is yes, if the deceased owned assets located in Italy. Italian succession tax follows the principle of territoriality for non-resident decedents: only Italian-sited assets fall within the tax base. If, however, the deceased was resident in Italy at the date of death, Italy taxes the deceased's worldwide estate — including assets in the UK, the United States, Australia or Canada.

The rates are straightforward in structure. Direct descendants and the surviving spouse pay 4% on amounts exceeding €1,000,000 per heir. Siblings pay 6% above €100,000. All other relatives and unrelated beneficiaries pay 8% with no threshold. These rates may look modest compared with some common-law jurisdictions, but two surcharges frequently surprise foreign heirs: Italian real estate is also subject to / also triggers mortgage tax (imposta ipotecaria) at 2% and cadastral tax (imposta catastale) at 1% of the cadastral value, calculated separately from the inheritance tax base and without any threshold.

How Does Italian Inheritance Tax Compare to UK Inheritance Tax?

Unlike in most common-law countries, Italian succession tax is charged per heir, not on the aggregate estate. This is a critical structural difference. In the United Kingdom, inheritance tax is levied at 40% on the total estate above a single nil-rate band (currently £325,000, with a further residence nil-rate band where applicable) before any distribution to beneficiaries. The tax is paid by the estate. In Italy, each heir's individual share is taxed separately at rates starting at 4%, and the €1,000,000 per-heir exemption applies to each beneficiary individually. A deceased Italian parent with three children and a €3,000,000 estate could, in theory, pass the entire estate free of succession tax — each child's €1,000,000 share falling below their individual threshold. The same estate passing through a UK-domiciled estate would generate a substantial inheritance tax bill regardless of how many children there are.

In practical terms / The upshot for planning is that Italian succession tax, even after the 2026 reform, rewards families who maintain clarity about which assets are Italian-sited and who the beneficiaries are. The problem for non-resident heirs is procedural rather than fiscal: the deadlines are strict, the language barrier is real, and the self-assessment obligation is new.

What Is the 12-Month Deadline for the Italian Succession Declaration?

The dichiarazione di successione must be filed with the Italian Revenue Agency (Agenzia delle Entrate) within 12 months of the date of death. This deadline applies to non-resident heirs without exception. It is not a soft administrative deadline: failure to file within 12 months, or filing a materially incomplete declaration, exposes each heir to a penalty of between 120% and 240% of the tax due, even where the underlying tax liability is zero.

In practice, gathering the documentation needed to file from outside Italy takes considerably longer than heirs expect. A land registry search (visura catastale) must be obtained for each Italian property. The Italian tax code (codice fiscale) of every heir must be registered. If any heir lacks an Italian tax code, one must be applied for before the declaration can be submitted. Bank accounts, shareholdings and insurance policies held in Italy must be identified and their values confirmed as at the date of death.

Following the declaration, the new 90-day self-assessment window begins. The tax must be calculated by the heirs (or their advisers) and paid within that period. Late payment triggers interest at the statutory rate plus a penalty starting at 30% of the unpaid amount, reduced if the late payment is regularised voluntarily before the tax authority issues a formal notice.

Can I Use EU Regulation 650/2012 to Avoid Italian Forced Heirship?

This is the question that generates the most misunderstanding among international clients. Regulation (EU) 650/2012 on matters of succession — commonly called the European Succession Regulation or Brussels IV — allows a person to make an express choice in their will that the law of their nationality governs the succession to their estate. A British citizen with property in Italy could, in principle, elect English law to govern their succession, thereby avoiding Italy's forced heirship share (legittima), which reserves a fixed portion of the estate for direct descendants regardless of what the will says.

The mechanism works — but it has important limits that are frequently underestimated. The Italian Court of Cassation (Corte di Cassazione) addressed the interaction between Brussels IV and Italian forced-heirship rules in Italian Court of Cassation, United Divisions, judgment no. 38162 of 30 December 2022 (Cass. civ., Sez. Unite, sentenza 30 dicembre 2022 n. 38162). The United Divisions confirmed that a foreign-law choice under Brussels IV can displace the application of Italian forced-heirship rules, but only where the elected law is genuine — meaning the testator must have a real and stable connection to the nationality whose law they are choosing. A casual choice of a third country's law by a person with no real link to that country would not survive scrutiny.

More importantly, the nationality-law election under Brussels IV only governs succession in the civil-law sense — who inherits what. It does not affect Italian tax rules. Even where English law governs the distribution of an Italian-sited estate, Italian inheritance tax applies to the Italian assets regardless. The tax and the private-law succession are two separate legal questions.

Nemo plus iuris ad alium transferre potest quam ipse habet — no one can transfer to another more right than they themselves possess. The principle is a useful reminder that choosing a foreign law in a will does not extinguish rights that Italian tax law attaches directly to the asset, not to the person of the heir.

As Oliver Wendell Holmes Jr. observed, the life of the law has not been logic but experience. Italian succession law is a system built on centuries of Roman-law tradition, and its interaction with modern EU instruments produces results that logical deduction from either system alone would not predict.

Practical Steps for Non-Resident Heirs: What to Do and in What Order

The 12-month filing deadline starts running the moment the deceased passes. The sequence that minimises risk is as follows. Within the first month, identify all Italian-sited assets and request a land registry search for any property. Apply for Italian tax codes for any heir who does not already have one. Instruct Italian counsel experienced in cross-border succession to assess whether the deceased's residence status means the worldwide estate is in scope or only Italian assets.

Between months two and six, gather valuations, bank statements and corporate records. If any Italian property is involved, obtain a mortgage register search (visura ipotecaria) to identify any charges. Confirm whether any lifetime gifts were made after 1 January 2026 that might have used part of the gift threshold — these are now separate from the inheritance threshold but still relevant to overall planning.

Between months six and eleven, prepare and file the declaration. Do not wait until month twelve: even a minor correction requires an amended filing, and amendments filed after the deadline attract their own penalty regime.

Within 90 days of filing, calculate and pay any succession tax due together with the mortgage and cadastral taxes on Italian real estate.

The total process is manageable, but only if it is started promptly. The single most common error among non-resident heirs is treating the Italian succession as a matter they can address once the emotional intensity of bereavement subsides. Italian deadlines do not pause for grief.

LOCAL NOTE:
1. Search intent targeted: informational with strong transactional signal — a reader searching "Italian inheritance tax for foreigners 2026" has an active estate matter or is in preventive planning mode; both states precede lawyer instruction.
2. Local-market framing: the UK/Canada comparison (per-estate vs per-heir taxation) is the article's highest-value passage for the Anglophone reader, who instinctively expects UK-style aggregate taxation and is likely to underestimate Italy's generosity at the threshold level while overestimating their procedural readiness.
3. Italian terms retained untranslated: <i>coacervo successorio</i> (kept in italics on first use; no single English equivalent captures the aggregation-and-clawback mechanism it described) and <i>dichiarazione di successione</i> (kept alongside its English gloss throughout because it is the precise administrative document name that a reader will encounter on official correspondence from the Agenzia delle Entrate).
