Portugal's NHR is dead. Greece requires a €500K investment. Switzerland bans work. A side-by-side comparison of every European HNWI tax regime — with the data advisors need.
The European HNWI tax landscape has changed dramatically in 2024-2026. Portugal gutted its Non-Habitual Resident (NHR) program. The UK abolished non-dom status. Greece tightened its investment requirements. For wealth advisors and families evaluating relocation, the question is no longer 'which country has the lowest rate?' but 'which regime actually works for my life, wealth structure, and succession plan?'
This guide provides a comprehensive, data-driven comparison as of April 2026, including the changes most advisors haven't yet incorporated into their planning.
| Country | Regime | Annual Cost | Duration | Can Work? | Investment Req. | IHT Exemption |
|---|---|---|---|---|---|---|
| Italy | Flat tax (Art. 24-bis) | €300K fixed | 15 years | Yes | None | Full (foreign assets) |
| Portugal | IFICI (ex-NHR) | 20% on qualifying income | 10 years | Yes | None | Partial |
| Greece | Non-dom flat tax | €100K fixed | 15 years | Yes | €500K in Greek assets | None specified |
| Switzerland | Lump-sum (forfait) | CHF 400K-1M+ | Ongoing | No | None | Canton-dependent |
| Malta | Non-dom | 15% min €5K/yr | Ongoing | Yes | None | N/A (remittance) |
| Cyprus | Non-dom | 0% on dividends | 17 years | Yes | None | N/A |
| Monaco | No income tax | €0 | Ongoing | Yes | Property deposit | None |
| UK (new FIG) | 4-year exemption | 0% (4 yrs only) | 4 years | Yes | None | None after 10 yrs |
Italy's €300,000 flat tax (raised from €200,000 in the 2026 Budget Law) covers all foreign-sourced income for 15 years. Family members can be added for €50,000 each. The regime also exempts foreign assets from IVIE (0.76% property tax), IVAFE (0.2% financial assets tax), and Quadro RW reporting. Most critically, foreign assets are exempt from Italian inheritance and gift tax — making it the only regime in Europe that offers both income and succession protection in a single package.
The killer advantage: under Italy's flat tax, a €50M foreign estate passes to heirs with €0 inheritance tax. Under the UK's new rules, the same estate faces £20M in IHT. Under France's rules, up to €22.5M. No other European regime matches Italy's combination of income + succession protection.
Portugal's NHR was the most popular HNWI regime in Europe from 2009 to 2023, attracting over 74,000 applicants. In late 2023, the government announced its abolition, replacing it in 2024 with the IFICI (Incentivo Fiscal à Investigação Científica e Inovação) — a narrower regime targeting specific professional categories: researchers, scientists, tech workers, and startup founders.
The new regime offers a 20% flat rate on qualifying Portuguese-source employment income for 10 years. Foreign passive income (dividends, interest, capital gains, rental income) is no longer exempt. For HNWI with substantial investment portfolios, Portugal's regime is no longer competitive. The 'golden era' of NHR is definitively over.
Greece offers a €100,000 annual flat tax for 15 years — half of Italy's. But the catch is substantial: applicants must invest at least €500,000 in Greek assets (real estate, government bonds, or shares in Greek companies). This locks significant capital in one of Europe's more volatile economies, with limited liquidity options and no guarantee of capital preservation.
Greece also lacks the infrastructure that HNWI families need: limited international schools (Athens has 3-4 vs Milan's 6+), healthcare ranked #29 by WHO (vs Italy's #2), and no city comparable to Milan as a global business and lifestyle hub.
Swiss lump-sum taxation (forfait) remains attractive for passive wealth holders. The minimum tax base is calculated on living expenses, typically resulting in annual payments of CHF 400,000 to over CHF 1M depending on the canton. However, the critical restriction is absolute: you cannot work in Switzerland under lump-sum taxation. For entrepreneurs, fund managers, or active investors, this is a dealbreaker.
Switzerland also lacks a clear inheritance tax exemption for foreign assets — treatment varies by canton and can be complex. And the path to citizenship is among Europe's longest: 10 years of residence plus 2-4 years of canton-level processing.
| Profile | Best Regime | Why |
|---|---|---|
| Active entrepreneur (€10M+ income) | Italy | Work rights + flat tax + succession. No other option combines all three. |
| Passive investor (€5M+ portfolio) | Italy or Switzerland | Italy if work rights needed. Switzerland if purely passive and prefer Alpine lifestyle. |
| Retiree with pension | Italy (7% regime) | 7% on foreign pension income in Southern Italy. Unbeatable rate. |
| Tech founder / researcher | Portugal (IFICI) | 20% on Portuguese employment income. Narrow but competitive for qualifying profiles. |
| Ultra-privacy, no work | Monaco | Zero tax, maximum discretion. But very expensive real estate and no EU passport path. |
| Young family, EU access priority | Italy | Best schools, healthcare, passport path (10 years), and 15-year tax certainty. |
Generally yes, but timing matters. If you've used Portugal's NHR for 5 years, you can move to Italy and apply for the flat tax if you meet the 9-of-10 year non-residency requirement (your Portugal years don't count as Italian residency). Each regime has its own eligibility window.
Italy has consistently applied grandfathering: if you opt in at €300K, you keep that rate for 15 years even if the tax is raised for new applicants. This has been proven twice (2024 and 2026 increases) and provides strong legal certainty.
For pure tax optimization, Monaco is unbeatable (zero income tax). But real estate is the world's most expensive (€50,000+/sqm), there's no EU passport path, no world-class healthcare system, and limited schooling options. It works for UHNWIs who want a base, not a home.
