For wealth managers and advisers: what happens to the mandate, the portfolio and the reporting when a UK client becomes Italian tax resident.
Your client tells you they are moving to Italy. The questions that follow are rarely the ones covered in relocation guides written for the client, because your exposure is different from theirs. Can you continue to act for them once they are resident in another jurisdiction? What happens to the portfolio you have built? What reporting obligations arise, and for whom? And at what point in the process do these things actually bite?
This guide is written for the adviser, not the client. It sets out the sequence of decisions, the points at which each becomes irreversible, and where local professionals are genuinely required.

This is the first question and the one most often deferred until it becomes urgent. Since the end of the transition period, UK investment firms no longer benefit from MiFID passporting rights into the EU. A UK-authorised firm cannot, as a general matter, provide investment services to a retail or elective professional client resident in Italy without either a local authorisation, an EU entity, or reliance on a narrow exemption.
The exemption most commonly invoked is reverse solicitation: where the client, at their own exclusive initiative, requests the service. Italian regulators, in line with ESMA guidance, interpret this narrowly. It does not cover an existing relationship that simply continues, it does not survive marketing or the offer of new products, and each new category of service may require a fresh demonstration that the initiative came from the client. Relying on it as a permanent structure for an ongoing discretionary mandate is not a defensible position.
| Firm structure | Position after client becomes Italian resident |
|---|---|
| UK-only authorisation | Continuation of a discretionary or advisory mandate is problematic. Requires specific legal review. |
| EU entity (Luxembourg, Ireland, Malta) | Generally workable. The relationship is typically transferred to the EU entity. |
| Swiss booking centre | Cross-border rules apply. Many Swiss institutions serve Italian residents under defined frameworks. Confirm the firm's Italian cross-border policy. |
| Execution-only, no advice | Lower risk, but not risk-free. Depends on facts and on how the relationship is documented. |
Practical point: this question should be answered before the client moves, not after. Discovering in month four that the mandate cannot continue in its current form is an avoidable conversation, and it is the most common way advisers lose a client at relocation — not to a competitor, but to a compliance decision they did not anticipate.
Italian tax residence for individuals turns on three alternative tests, any one of which is sufficient, applied for the greater part of the tax year — more than 183 days. The tests are registration with the resident population register, domicile in Italy in the sense of the centre of personal and family interests, and habitual abode.
Two consequences follow that matter for planning. First, registration alone can establish residence even where the client spends less time in Italy than expected, so the timing of the anagrafe registration is a planning decision rather than an administrative formality. Second, because the test is applied to the tax year as a whole, Italy does not operate split-year treatment as a domestic rule: a client who becomes resident is generally resident for the entire calendar year. The UK–Italy double tax treaty contains tie-breaker provisions that may allocate residence for treaty purposes, but the domestic starting point is the full year.
From the UK side, the Statutory Residence Test governs departure, and the temporary non-residence rules mean that certain income and gains realised during a period of non-residence shorter than five complete tax years can be taxed on return. A client who may come back to the UK within five years needs this modelled before disposing of assets.
Italy's treatment of collective investments turns on a distinction that has no direct UK equivalent and that catches most advisers the first time. Funds that are UCITS-compliant and marketed in the EU, or established in EU or EEA jurisdictions subject to supervision, fall into the harmonised category and their income and gains are subject to the 26% substitute tax. Everything else is non-harmonised, and gains are added to ordinary income and taxed at progressive IRPEF rates reaching 43% before regional and municipal surcharges.
Post-Brexit this matters enormously for UK holdings. UK-domiciled OEICs and unit trusts are no longer automatically treated as harmonised, and whether a given fund qualifies depends on its current status and on whether it provides the data Italian intermediaries require. Many do not.
| Holding | Italian treatment | Planning note |
|---|---|---|
| UK OEIC / unit trust | Likely non-harmonised. Gains potentially at IRPEF rates. | Review line by line before the move. Consider restructuring into EU-domiciled equivalents. |
| Investment trust (listed company) | Taxed as a shareholding at 26%. | Often more efficient in Italy than the OEICs alongside it. Frequently overlooked. |
| Irish or Luxembourg UCITS | Harmonised. 26% substitute tax. | Generally the cleanest structure for an Italian-resident client. |
| Direct equities and bonds | 26% on gains. Italian government bonds at 12.5%. | No structural issue. |
| ISA | No Italian recognition. Wrapper disregarded, underlying taxed. | The tax shelter does not travel. Consider realising gains before residence. |
| SIPP | Foreign pension. Treatment depends on drawdown structure and regime elected. | Covered by the flat tax if elected. Otherwise requires specific analysis. |
For clients with substantial foreign income, the substitute tax regime under Article 24-bis TUIR replaces Italian taxation on all foreign-source income with a fixed annual payment of €300,000 for elections made from 2026, plus €50,000 per additional family member. Elections made earlier remain grandfathered at their original amount for the full fifteen-year duration.
From an adviser's perspective the regime does three things that materially simplify the position. Foreign-source investment income falls outside Italian taxation, so the harmonised versus non-harmonised distinction becomes largely irrelevant for assets held abroad. The RW reporting obligation and the IVAFE wealth tax on foreign financial assets do not apply. And foreign assets are excluded from Italian inheritance tax for the duration of the regime.
The regime does not cover Italian-source income, and capital gains on qualified shareholdings disposed of in the first five years are excluded. It requires the client to have been non-resident for at least nine of the preceding ten years.
The break-even is generally reached somewhere around €700,000 to €900,000 of annual foreign income, depending on composition. Below that, ordinary taxation with the 26% substitute rate on financial income is often more efficient — and that is the scenario in which portfolio composition, harmonised status and reporting all become live issues.
Outside the flat tax regime, an Italian-resident individual must report foreign financial assets and foreign real estate annually on the RW section of the tax return. This applies to accounts, portfolios, insurance wrappers, shareholdings and property, regardless of whether income arises. Penalties for omission run from 3% to 15% of the undeclared amount, doubling for assets held in jurisdictions Italy treats as non-cooperative.
Two wealth taxes accompany the reporting. IVAFE applies at 0.2% on the value of foreign financial assets, rising to 0.4% for assets held in blacklisted jurisdictions. IVIE applies at 1.06% on foreign real estate, with relief where the property is the main residence.
The client's custodian will not do this. If assets are held outside Italy, there is no Italian withholding agent and the reporting burden sits entirely with the client and their Italian accountant. Advisers who assume the position is handled automatically, as it would be with an Italian intermediary, create a problem that surfaces at the first filing.
Separately, the Common Reporting Standard means that accounts held by an Italian tax resident in the UK, Switzerland, Singapore, Hong Kong and the other participating jurisdictions are reported automatically to the Italian authorities. Any planning has to assume full transparency.
| When | What needs to happen |
|---|---|
| 12–18 months before | Regulatory review of whether the mandate can continue. Portfolio analysis against harmonised rules. Preliminary flat tax modelling. UK temporary non-residence check if a return within five years is possible. |
| 6–12 months before | Portfolio restructuring where indicated. Realisation of gains while still UK resident where beneficial. Decision on ISA position. SIPP structure reviewed. |
| 3–6 months before | Italian accountant appointed. Banking introductions. Visa or permit where applicable. School applications for the following academic year. |
| Arrival | Codice fiscale, anagrafe registration, healthcare registration, permit collection. Note that anagrafe registration timing affects the residence determination. |
| First filing | Flat tax election, if applicable, is made on the first Italian tax return. First RW cycle if outside the regime. |
Not everything requires an Italian adviser, and part of the value of getting this right is knowing where the line falls. An Italian commercialista is required for the tax return, the flat tax election and RW reporting, and there is no workaround. A notary is required for any property transaction and cannot be substituted. Immigration counsel is required where a visa or permit is involved. Italian legal advice is required for wills and succession where Italian assets or residence are involved, because the interaction between Italian forced heirship rules and a foreign will is not intuitive.
Conversely, portfolio management, financial planning and the client relationship itself do not need to move to Italy, provided the regulatory question in section one has been resolved. This distinction is worth making explicitly with the client early, because the assumption that relocating means changing adviser is common and rarely examined.
No. There is no requirement to hold assets in Italy, and most HNWI clients do not. What changes is the reporting position: assets held abroad must be declared annually on the RW form and are subject to IVAFE, unless the flat tax regime applies, in which case neither obligation arises. A local current account is usually needed for practical purposes such as utilities and rent, but that is a separate matter from custody.
It depends on your firm's authorisations. A UK-only authorised firm faces a genuine regulatory question, since MiFID passporting no longer applies and reverse solicitation is interpreted narrowly in Italy. Firms with an EU entity generally transfer the relationship to it. This needs to be resolved with your compliance function before the client moves, not after.
Foreign-source income within the scope of the substitute tax is generally covered, which in most cases includes dividends from a controlled foreign company. The interaction with Italy's CFC rules has technical limits and depends on the structure and on where activity is genuinely carried out, so it requires case-specific analysis rather than a general answer.
Italy does not recognise the ISA wrapper. The tax shelter does not travel: the underlying holdings are taxed according to their own character, which for UK-domiciled funds usually means the non-harmonised treatment. Realising gains while still UK resident, before Italian residence begins, is frequently the more efficient route.
For a client with a portfolio, a possible corporate structure and a family, twelve to eighteen months of planning before the move is realistic. The decisions that matter most — regulatory position, portfolio restructuring, gain realisation — have to be made before Italian residence is triggered, and afterwards the options narrow considerably. Clients with simpler affairs move faster.
The risk is real but it is not primarily competitive. Clients are usually lost at relocation for one of two reasons: a regulatory issue that forces a change of provider, or the accumulation of practical problems in Italy that the adviser cannot solve and that eventually get solved by someone local, who then becomes the trusted point of contact. Both are addressable if handled early.
