ABSTRACT: From 1 January 2026, Italy's lump-sum substitute tax under Article 24-bis of the Italian Income Tax Code rose from €200,000 to €300,000 per year for new entrants, with a per-dependent surcharge doubling to €50,000. For high-net-worth individuals weighing relocation from the UK, USA, Australia or the UAE, the arithmetic is now sharply different — and the regime's three least-understood features can turn an apparently simple tax shelter into a costly mistake. This article compares the Italian flat tax against Greece's non-domicile regime, Portugal's NHR successor and the UAE's zero-rate environment so you can assess which option genuinely wins for your circumstances.

Imagine you have just sold a company for €12 million and you are asking your adviser where to live next. Italy's flat-tax brochure says: pay €300,000 a year, and your foreign income is sheltered. Greece says: pay €100,000 a year, same idea. Portugal has rebuilt its preferential regime around a 20% flat rate on qualifying income. The UAE says: pay nothing at all. Each answer is true, and each is dangerously incomplete.

The comparison only becomes useful when you run the numbers honestly — and when you understand what each regime actually does and does not protect.

How much does Italy's flat tax cost in 2026?

Article 24-bis of the Testo Unico delle Imposte sui Redditi (Italian Income Tax Code, commonly known as the TUIR) was amended by Law 199/2025, which was published in the Gazzetta Ufficiale and took effect on 1 January 2026. For any individual who transfers tax residence to Italy on or after that date and qualifies for the regime, the annual substitute tax is now €300,000. Each dependent family member who also opts into / elects the regime adds a further €50,000.

The regime lasts a maximum of 15 years and cannot be reactivated once it lapses or is voluntarily surrendered. Critically, grandfathering applies: individuals who elected under the original €100,000 rate (introduced in 2017) or under the transitional €200,000 rate continue paying their original amount for the remainder of their 15-year window. Only new entrants from 1 January 2026 face the higher charge.

To qualify, you must not have been Italian tax resident for at least nine of the ten years immediately preceding the election. Residence is established by transfer of your domicile or habitual abode to Italy within the meaning of Article 2 TUIR and Article 43 of the codice civile (Italian Civil Code). Physical presence alone, if it triggers the 183-day rule, will create full tax residence whether or not you have formally elected the regime.

The three traps that cost people the most

The economics of the Italian flat tax are straightforward once you understand what the regime does not cover. Three misunderstandings are almost universal among new clients / prospective clients.

First, Italian-source income is taxed normally under ordinary progressive rates of 23% to 43%, plus regional and municipal surcharges. The substitute tax shelters only foreign-source income. A British executive who relocates to Milan and continues to draw a salary from an Italian employer, or who sells an Italian property, will pay full Italian tax on those receipts. The flat rate of €300,000 does not touch them.

Second, foreign tax credits are generally unavailable against income sheltered by the substitute. If a foreign country withholds tax at source on a dividend or royalty, that withholding is an absolute cost: Italy will not allow a credit because the income is not subject to Italian tax in the normal sense. Depending on your portfolio structure and the treaties involved, this can make the effective rate on foreign income significantly higher than it first appears.

Third, the regime only pays off with substantial foreign income. At €300,000 per year, the substitute only outperforms Italy's top marginal rate of 43% once your shielded foreign income exceeds roughly €700,000 to €750,000 annually. Below that threshold, an ordinary Italian taxpayer paying progressive rates would pay less. This figure rises further once you account for eliminated treaty credits and the Italian wealth taxes on foreign assets — IVIE (the levy on foreign real estate) and IVAFE (the levy on foreign financial assets) — which are waived under the regime but are relatively modest for most portfolios.

How does Italy's new resident tax compare to Greece's non-dom regime?

Greece introduced its own non-domicile regime for high-net-worth individuals in 2020 under Article 5A of the Greek Income Tax Code. The annual lump sum is €100,000, with €20,000 per dependent family member, for a maximum of 15 years. The structural logic is identical to Italy's: foreign income is sheltered by the flat payment, Greek-source income is taxed normally, and the qualifying condition is prior non-residence in Greece for seven of the previous eight years.

At first glance Greece appears three times cheaper. The correct question is whether the overall package — lifestyle, infrastructure, double-tax treaty network, healthcare, rule of law, and political stability — justifies the difference. [text truncated — unflaggable]ateral double-tax treaties with over 100 countries, including comprehensive agreements with the United States and the United Kingdom that were negotiated over decades. Greece's treaty network is narrower and some of its older agreements are less favourable on dividend and interest flows. For an investor with complex multi-jurisdictional income, Italy's treaty infrastructure can, in certain scenarios, offset a portion of the cost difference — though this must be modelled case by case with a tax adviser familiar with both systems.

There is also a structural difference in enforcement posture. The Italian Revenue Agency (Agenzia delle Entrate) has invested heavily in automatic exchange of information under the OECD's Common Reporting Standard and under Directive 2011/16/EU (DAC) as progressively amended. Greece's enforcement capacity has historically been less aggressive, but the gap is narrowing under EU pressure and the DAC6 and DAC8 mandatory disclosure regimes.

Is Italy's €300,000 flat tax worth it?

Unlike in most common-law countries — where residency-based taxation means you pay tax on your worldwide income from the moment you become resident, with limited carve-outs and complex foreign income rules — Italy's Article 24-bis regime offers a genuine, legislatively certain ring-fence around foreign income for up to 15 years. The UK's former non-domicile regime (abolished for new claimants from April 2025) attempted something similar through the remittance basis, but it was subject to remittance complexity, annual charges, and ultimately political abolition. Italy's regime is statutory, settled in the TUIR, and the 2026 amendment reinforces rather than undermines its architecture.

Portugal's successor to its Non-Habitual Resident regime — rebranded as the Incentivo Fiscal à Investigação e Inovação (IFICI) under Law 82/2023 — takes a fundamentally different approach. Rather than a lump-sum substitute, it offers a 20% flat rate on qualifying Portuguese-source income (mainly employment and business income in high-value-added activities) and, in some cases, exempts or reduces tax on foreign income. It targets professionals and researchers more than passive-wealth holders, and it does not offer the same clean exemption of foreign investment income that Italy's regime provides. For a retired business-owner living off dividends and capital gains, Italy's structure is in practice cleaner.

The UAE offers zero personal income tax — full stop. For an individual with no meaningful ties to a particular European country and no requirement to spend time in a specific location, this is arithmetically unbeatable. The UAE does not operate a territorial income tax, has no capital gains tax, and has signed a growing number of double-tax treaties. However, substance requirements for UAE tax residence are increasingly real: the Federal Tax Authority expects genuine physical presence and economic substance, and OECD peer review under the Global Forum on Transparency is tightening the conditions under which treaty benefits will be accepted by counterpart states. A Monaco or UAE certificate of residence without genuine substance is attracting challenge from HMRC, the ATO, and the IRS with increasing frequency.

The Latin maxim nemo potest esse simul ubique praesens — no one can be present everywhere at once — is the practical constraint that every residence-planning exercise eventually hits. You must actually live somewhere. The right regime is the one that fits where you genuinely want to spend your time.

Can I combine Italy's flat tax with the 7% retiree regime?

No. The 7% flat-rate regime for foreign pensioners relocating to small Italian municipalities (Article 24-ter TUIR) and the Article 24-bis lump-sum regime are mutually exclusive. Both offer preferential treatment of foreign income, but they operate on different legal bases, target different taxpayer profiles, and cannot be elected simultaneously. An individual who qualifies for both must make a single election and commit to it for the duration.

For pensioners with modest foreign pension income — say, a British state pension and a small occupational pension — the 7% regime is almost certainly more economical, since the tax is applied as a percentage of the actual foreign income rather than as a flat charge regardless of income level. For a retiree with a €500,000 annual pension, 7% produces a charge of €35,000 — dramatically cheaper than €300,000. The Article 24-bis regime starts to look attractive only once foreign income is very large, or where the foreign income source is difficult to characterise (so a percentage-based regime creates uncertainty) and the taxpayer values the absolute certainty of a fixed annual payment.

What advisers and mobile wealth should do before deciding

The decision framework is not complicated in principle, though it is detail-intensive in execution. Start with three questions: Where do you actually want to live, and for how long each year? What is the source — and the legal character — of your income? And what happens to your treaty position in each scenario?

Italy's regime requires genuine Italian residence. You must register at the anagrafe (the municipal residents' register), obtain an Italian tax code (codice fiscale), and be prepared to demonstrate that Italy is your centre of vital interests. The Italian Revenue Agency's Circular No. 17/E of 23 May 2017 (which remains the primary administrative guidance on Article 24-bis) sets out the documentary standards expected at the time of election, and subsequent practice confirms that residency substance is scrutinised — particularly for individuals who also retain property and social ties in their country of origin.

The election is made in the annual Italian tax return for the year of transfer. It cannot be made retrospectively for a prior year. Once made, it is irrevocable for that year but can be voluntarily surrendered in subsequent years — after which the regime terminates permanently.

On the foreign-asset side, note that Article 24-bis electors are entirely exempt from IVIE, IVAFE, and from the Quadro RW foreign-asset disclosure that otherwise applies to Italian residents. This is a genuine administrative simplification, though it does not reduce the underlying compliance obligations in the countries where the assets are held.

As the legal scholar Lawrence Zelenak observed in his comparative work on schedular tax systems, a flat substitutive tax looks simple on paper but creates a new layer of complexity wherever ordinary rules still apply — which, in Italy's case, is anywhere Italian-source income enters the picture.

LOCAL NOTE:
1. Search intent: informational — reader is researching and comparing options before instructing an adviser; snippet-capture potential on comparison and break-even queries.
2. Local-market framing: written for UK, US and Australian HNWIs and their advisers; framing anchors on the abolition of the UK non-dom regime as the trigger event and on common-law expectations about worldwide taxation; UAE comparison added for Gulf-resident and internationally mobile readers.
3. Italian terms kept untranslated: IVIE and IVAFE retained in italics alongside their English descriptions because no single-word English equivalent exists and the Italian acronyms are the terms used in all Italian compliance filings; anagrafe retained once with English gloss because it has no direct common-law equivalent and is the operative term in Italian administrative practice.
