## Concept

CRS is the infrastructure that ended the era of banking secrecy. The Common Reporting Standard, developed by the OECD, requires financial institutions worldwide to identify the tax residency of their clients and report account data once a year to each client's country of residence. More than 115 jurisdictions now take part; in 2024 alone they exchanged information on over 170 million financial accounts worth close to EUR 13 trillion. Inside a participating country, an unreported foreign account has stopped being a realistic option.

## Where CRS Came From

The standard is a child of the 2008 financial crisis. With public finances under strain, the G20 pressed the OECD to close the model in which wealth moved offshore and then dropped out of view. The template already existed in the US FATCA regime; the OECD generalised it, published the Common Reporting Standard in 2014, and the first jurisdictions exchanged data in 2017. A handful of early adopters has grown into a near-universal grid of more than 115 jurisdictions, and the annual volumes — over 170 million accounts in 2024 — show how routine the exchange has become.

## How Automatic Exchange Works

The logic is simple. When opening an account, a bank or broker determines which countries the holder is a resident of (and for structures, the controlling persons as well). Once a year, the institution reports a set of data to its tax authority: name, address, tax identification number, account number, year-end balance, interest, dividends, and proceeds from asset sales. The tax authority passes this to counterparts in the holder's country of residence. This is AEOI—automatic exchange of information: not on request, but automatically and annually.

## How a Bank Decides Where You Are Resident

Reporting turns on residency, so banks put real effort into fixing it. A new client signs a self-certification declaring every tax residency, and the institution tests that claim against the indicia already in its files: a home or mailing address, a phone number, a standing payment instruction, a power of attorney pointing somewhere else. A mismatch prompts questions rather than a quiet pass. For accounts held through passive companies or trusts, the bank looks through to the controlling individuals and reports them by name. A defensible tax residency is the first building block of any cross-border plan, which is why thin paper residencies that do not match the facts tend to come apart.

## CRS and FATCA: What's the Difference

FATCA is the American predecessor to CRS: from 2010 the United States made banks everywhere report accounts held by US taxpayers, backed by a 30% withholding threat. CRS took the same mechanism and made it multilateral, with one asymmetry. The United States does not join CRS and reciprocates only narrowly under its own FATCA agreements, which is why US accounts are sometimes called a transparency loophole — a real gap, but a narrower one than the marketing suggests. For every other major financial centre the network is effectively complete, and a tax authority routinely cross-checks the incoming feed against domestic filings.

> ⚙️ The "US loophole" is real but shallow. Because the United States collects under FATCA instead of joining CRS, it shares back less than it receives — an asymmetry that helps some foreigners banking in the US far more than it helps Americans, who stay fully reportable worldwide under FATCA. With US beneficial-ownership rules tightening as well, treating the country as a permanent blind spot is a planning mistake.

## What Falls Under Reporting

A reportable account is one whose holder — or, for a passive company or trust, whose controlling individuals — is tax-resident in another participating jurisdiction. The exchange covers depository and custodial accounts and many insurance and investment products, and it looks through passive structures to the people behind them. Because CRS keys on tax residency rather than citizenship, sound planning starts with a residency that is honestly determined and documented; concealing it does not survive automatic exchange.

## What the Exchange Cannot See

CRS moves balances and income figures, not motive or context, and it says nothing about assets held outside the financial system: real estate, art, physical gold, a private operating business. That is the honest limit of the regime. The limit is smaller than it first looks, because the account feed is cross-checked against beneficial-ownership registers, CFC reporting and domestic returns, and the gaps between those datasets are exactly what opens an enquiry. A nominee holder or an extra layer of entities does not erase the controlling person; it adds a line for the analyst to follow. Any plan that relies on the authority never joining two records together is living on borrowed time.

## CRS 2.0 and CARF: The Next Phase

Transparency is now reaching digital assets and e-money. The amendments the OECD approved in 2023 — the updated standard informally called CRS 2.0, plus a separate Crypto-Asset Reporting Framework (CARF) — took effect on 1 January 2026. CRS 2.0 brings specified electronic-money products and central bank digital currencies into scope; CARF makes crypto exchanges and custodians report on their clients much as banks already do. Roughly 48 jurisdictions will run their first exchanges in 2027, and about 27 more — including the United States, Hong Kong, Singapore and the UAE — follow in 2028. In the EU the package arrives through the DAC8 directive, which reaches any platform serving EU clients wherever it is based.

### What this means for private clients

For anyone holding crypto, the practical point is that a wallet at a regulated exchange is now about as visible as a brokerage account, and the first CARF data reaches tax authorities in 2027. Together, CRS 2.0, CARF and DAC8 close the last large category that used to sit outside automatic exchange. The sensible response is plain discipline: align reporting with residency, keep structures substantive rather than decorative, and assume that every regulated account, fiat or crypto, is visible to your home tax authority.

> 🧭 Practical takeaway: settle an honest tax residency before anything else, report what the exchange will already reveal, and keep structures for reasons that survive scrutiny — asset protection, succession, governance. The five-flags instinct still works; automatic exchange has simply removed concealment from the toolkit and left the rest of cross-border planning intact.

> 💡 CRS is an automatic, annual exchange of financial-account data keyed to tax residency rather than citizenship — the mirror image of FATCA. From 2026 the amended standard and CARF extend the same logic to e-money and crypto, with the first exchanges due in 2027. Build the plan on a residency you can defend; secrecy is no longer one of the available inputs.
