Concept
In fifteen years, the global system has turned upside down. Banking secrecy as a planning tool is dead; in its place stands an infrastructure of automatic exchange. Tax authorities learn about foreign accounts by default—only the format and timeline for data to reach your country of residence remain open questions. Private wealth planning has become a compliance discipline: structures are evaluated by whether they can withstand full visibility.
How Banking Secrecy Disappeared
The collapse began in 2009: Swiss bank UBS, under U.S. pressure, paid $780 million and for the first time handed over client names—the symbolic end of absolute banking secrecy. In 2010, Congress passed FATCA and obliged banks worldwide to report on U.S. taxpayers. The OECD picked up the approach: CRS appeared in 2014, with the first automatic exchanges taking place in 2017–2018. Leaks—Panama Papers (2016), Paradise Papers (2017), Pandora Papers (2021)—only accelerated the political consensus. We examine the long history of havens separately.
By the mid-2020s, automatic exchange covered more than a hundred jurisdictions and tens of millions of accounts per year. Hiding capital "outside the exchange" is technically possible only in a few relic locations, and the price is disconnection from normal banking: banks from opaque jurisdictions lose correspondent accounts. Full visibility has become the backdrop against which all planning is now built.
Four Pillars of the System
CRS: Automatic Exchange on Accounts
CRS covers more than 100 jurisdictions: banks annually transmit balances, income, and data on controlling persons to the tax authority of the client's country of residence. The updated standard (CRS 2.0) takes effect from 2026, with first reports under it going out in 2027; the perimeter is expanded to electronic money, certain payment products, and CBDCs. Reporting is built on self-declaration of residence: incorrect self-certification does not stop the exchange anyway and leaves discrepancies that banks and tax authorities later reconcile. We examine the mechanics of the standard in the CRS overview.
FATCA: The American Vertical
The U.S. does not participate in CRS—it has its own vertical. FATCA (since 2010), FBAR, and Form 8938 turn any contact with a U.S. person into a separate compliance circuit: its own reporting thresholds, penalties for silence, the IRS's special view of foreign trusts (Form 3520) and PFICs. The paradox of the system is that the U.S. itself remains one of the most opaque jurisdictions for non-residents: it collects data on its citizens worldwide, but gives almost nothing back through CRS. We examine the American circuit in the material on FATCA, FBAR and Form 8938.
CARF: Crypto Ceases to Be a Blind Spot
The Crypto-Asset Reporting Framework transfers CRS logic to crypto assets: providers (exchanges, custodians, some DeFi interfaces) report on clients. The schedule is split into waves: around 76 jurisdictions have signed up. Most collect data from 2026 and exchange from 2027; the second wave — Switzerland, Singapore, the UAE, Hong Kong, Turkey and others — collects from 2027 and exchanges from 2028; the U.S. only comes into exchange in 2029. One point worth holding onto: CARF transmits aggregates of transactions over the period, not wallet balances the way CRS does for accounts. The OECD keeps revising the named composition of the waves, so check it against the current Global Forum commitment list rather than a figure in an article. In the EU, the same rules are introduced by DAC8 (Directive 2023/2226). We examine the tax consequences for holders in the crypto materials.
Registers and Scheme Disclosure
Beneficial owner registers, after the EU Court decision of November 22, 2022 (cases C-37/20 and C-601/20), lost their public access regime: the court deemed the openness of UBO data a disproportionate interference with private life. The EU AML package of 2024 (Directive 2024/1640) established access by "legitimate interest"—for banks, tax authorities, obliged entities, journalists, and NGOs; registers closed to the general public. In parallel, DAC6 obliges advisors to disclose cross-border schemes by hallmarks, and GAAR and the principal purpose test allow tax authorities to ignore structures without business purpose. The banking side of the same system is AML/KYC checks and source of funds; we examine this circuit separately.
What This Changes in Planning
Only three things work. First—lawful special regimes: non-dom, flat tax, and territorial systems provide low rates with full transparency. Second—substance: a structure with real presence—office, people, decisions on the ground—withstands both exchange and GAAR. Third—order in the past: voluntary disclosure and amnesties are almost always cheaper than waiting for a letter from the tax authority with already-received exchange data. For holders from Russia, this is supplemented by foreign account reporting and the CFC regime.
Where This Is Heading
The vector is one—transparency by default. CARF and DAC8 in 2026–2027 close the crypto channel, CRS 2.0 tightens electronic money and CBDCs, beneficial owner registers and exchange on request stitch data together. Tax authorities increasingly rarely request information manually and increasingly often compare already-received arrays: a discrepancy between a declaration and exchange data itself becomes grounds for an audit.
What remains workable are structures that honestly live under full visibility: real presence, lawful low-tax regimes, carefully closed past. For holders from Russia, the practical minimum is a sober view of exit taxes when changing residence and understanding how exchange overlaps with trusts and holding structures.
Questions and Answers
Are there jurisdictions left outside the exchange?
Formally—a handful, and holding capital there means cutting yourself off from normal banking: banks from opaque jurisdictions lose correspondent accounts. Practical answer: no, planning "outside the exchange" is no longer possible.
Does the tax authority see my spending, or only balances?
CRS transmits balances and income on the account, not transactions. But a discrepancy between declared income and balances is itself a trigger for a request, and within the country banks report according to their own rules.
What must a trust disclose?
The trustee is a reporting entity under CRS: settlor, beneficiaries, and protector fall into the exchange as controlling persons. A trust does not hide assets from the tax authority—it solves other tasks: succession, protection, management.
