The Era of Financial Transparency: Multi-Residency Is About Options, Not Hiding Money

CRS, the global minimum tax and Europe's golden-passport ruling ended the era of hidden money. Multi-residency now pays only when it is structured transparently.

The days when an offshore account could sit quietly, unseen by anyone at home, are ending: more than 100 jurisdictions already exchange financial account data automatically under the Common Reporting Standard (CRS), and Vietnam has signed the multilateral convention that underpins it and is building the infrastructure to take part. For Vietnamese investors, this does not make a second residency less valuable — it removes the ways of misusing one. Multi-residency is worth having when it rests on transparency: knowing where you are tax-resident, reporting correctly, and working with a licensed tax adviser.

Most conversations about tax transparency happen in Paris, Brussels or Washington, and they revolve around multinationals and offshore financial centres. The Vietnamese investor sits somewhere else entirely. They do not run cross-border funds, yet more and more of them hold bank accounts, property and residence cards in several countries. For them, the real question is not "how do I stay invisible?" but "how do I make sure everything I own still stands up when everyone can see it?"

Offshore accounts are no longer a private matter

How CRS works: The standard, developed by the OECD and the G20, requires financial institutions to collect each account holder's tax residence and report it, so that the local tax authority can pass the data automatically to the country where that person is resident. According to HMRC's own guidance, 45 jurisdictions signed the multilateral competent authority agreement in October 2014, the first exchanges began in 2017, and more than 100 jurisdictions now exchange financial account information (HMRC — IEIM400080).

No whistleblower required: What matters most is that CRS runs on routine, not suspicion. The bank asks, the client self-certifies their tax residence, and the data moves on a schedule. If an account is opened under a false residence, the information can go to the wrong country or nowhere at all — which is precisely the gap regulators have been closing for almost a decade.

Where Vietnam stands on the transparency map

The steps already taken: Vietnam joined the Global Forum on Transparency and Exchange of Information for Tax Purposes in December 2019 and signed the Convention on Mutual Administrative Assistance in Tax Matters on 22 March 2023, becoming its 147th participant. That convention is the main legal instrument for putting CRS into practice (Thoi bao Tai chinh Viet Nam, 2023).

A timeline still open: As reported by Thoi bao Tai chinh Viet Nam on 9 September 2026, Vietnam has not yet formally set a start date for CRS exchanges, but has been completing the legal basis and preparing the infrastructure. It has also committed to two-way exchange of country-by-country reports from March 2027, and expects to begin automatic exchange of crypto-asset information under the CARF framework from September 2028 (Thoi bao Tai chinh Viet Nam, 2026). Earlier, Decision 948/QD-TTg of 27 May 2026 approved a national action plan on exchange of information on request, and on 24 July 2026 Vietnam formally asked the Global Forum for a fresh assessment.

The direction is clear even if the date is not. Sensible investors do not wait for the rules to reach them before putting their paperwork in order.

The global minimum tax and the golden-passport ruling

A 15% floor: On 8 October 2021 the G20/OECD Inclusive Framework on Base Erosion and Profit Shifting agreed a 15% global minimum tax (GOV.UK, 2022). Vietnam applied it from 1 January 2024 through Resolution 107/2023/QH15, for multinational groups with consolidated revenue of at least EUR 750 million (LSVN, 2023). It does not apply to a private family investor, but it captures the spirit of the times: a tax advantage now survives only when real activity stands behind it.

Citizenship is not a transaction: On 29 April 2025 the Court of Justice of the European Union ruled that Malta's 2020 investor citizenship scheme breached EU law, because granting nationality in exchange for predetermined investments amounts to the "commercialisation" of Union citizenship (CURIA — Press release 52/25, 2025). The ruling concerned citizenship, not residence permits, but the message was unmistakable: Europe wants to see a genuine link.

Residency is not a tax shield: Back in October 2018, the OECD flagged residence and citizenship-by-investment schemes as high-risk for CRS where they offer a personal tax rate below 10% on offshore financial assets without requiring at least 90 days of physical presence, and it advised banks to ask further questions when a client's self-certified tax residence looks unreliable (Mondaq, 2018). A residence card, in other words, does not automatically make you tax-resident where it was issued.

What Vietnamese investors often get wrong

A foreign residence card does not end Vietnamese tax residence: Under Vietnam's personal income tax rules, you are a resident individual if you are present in Vietnam for 183 days or more in a calendar year or in any 12 consecutive months from your first arrival, or if you have a habitual place of residence in Vietnam. Residents are taxed on income arising both inside and outside the country. Someone with a habitual residence in Vietnam who spends fewer than 183 days there is still treated as resident unless they can prove tax residence elsewhere, usually with a certificate of residence issued by a foreign tax authority (Ke toan Thuan Thien, 2026).

A new law, the same tests: Personal Income Tax Law No. 109/2025/QH15, passed by the National Assembly on 10 December 2025, took effect on 1 July 2026 (Thi truong Tai chinh Tien te, 2026). It keeps both the 183-day test and the habitual-residence test, so the underlying logic has not changed.

Home, tax home and passport are three different questions: Many investors treat them as one. In practice you can hold a Vietnamese passport, carry a Cypriot residence card and still be tax-resident in Vietnam — it depends on where you actually live and work.

A practical strategy for Vietnamese investors

Map your tax residence before you buy another residency. Be clear about where you are tax-resident today, how many days you plan to spend in each place, and how that picture shifts once a new home enters it. Choose a programme only after this question has an answer — the NAC programme comparison is a good place to start.

Get the self-certification right from the first form. When a foreign bank asks about your tax residence, answer truthfully and consistently with your records in Vietnam. A careless answer at account opening can turn into a serious problem years later.

Keep records as if you will be asked tomorrow. Purchase contracts, transfer receipts, rental statements, certificates of residence — file all of it systematically. For an apartment in Limassol under the Cyprus residency programme, both the source of funds and the rental income should be explainable at each end.

Work with licensed tax advisers in both countries. Double tax treaties, credits for foreign tax paid, the treatment of rental income and capital gains — these are questions for licensed professionals, not word of mouth. NAC does not give tax advice, but we always encourage clients to bring in an independent adviser from day one.

Frequently asked questions

Is Vietnam already exchanging CRS information with other countries?

As of September 2026, Vietnam has not formally set a start date for CRS exchanges, but it signed the multilateral convention in 2023 and is completing the legal and technical groundwork. It is wise to organise your records as though exchanges will happen.

If I hold residency abroad, do I stop paying tax in Vietnam?

Not automatically. Vietnamese tax residence depends on your days of presence and your habitual residence, not on which residence cards you hold. A licensed tax adviser can assess your particular situation.

Does the Malta ruling affect permanent residence programmes?

The 29 April 2025 judgment targeted Malta's investor citizenship scheme, not residence permits. It does, however, reflect a wider expectation of a genuine link with the granting country, so investors should favour programmes with a solid legal footing and understand the obligations that come with them.

NAC strategic insight

Financial transparency is not a threat to Vietnamese investors who do things properly — it is a filter. Once hidden money has nowhere left to go, the real value of multi-residency becomes easier to see: the right to live, study, do business and protect a family in more than one place, on a structure that any tax authority would recognise as sound. Those who organise their affairs early, before Vietnam formally joins CRS exchanges, will act from a position of choice rather than catch-up.

NAC works alongside Vietnamese investors to choose residency programmes and assets that fit long-term goals, always in step with the client's own licensed tax advisers and lawyers. If you want to review an existing structure, or start transparently from the beginning, book a consultation with NAC.
