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 determine clients' tax residency and annually transmit account data to their country of residence. Today, over one hundred jurisdictions participate in the exchange—and "hiding" an account in a participating country is virtually impossible.
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.
CRS and FATCA: What's the Difference
FATCA is the American predecessor to CRS: the United States required banks worldwide to report on accounts of its taxpayers. CRS took the same idea and made it multilateral. The fundamental difference is that the United States itself does not participate in CRS and transmits data in return only on a limited basis—which is why in certain circles, U.S. accounts are sometimes called a "loophole" in global transparency. For other countries, the network is nearly complete.
What Falls Under Reporting
Reportable accounts are accounts whose holder is a tax resident of another participating jurisdiction. The exchange covers depository and custodial accounts, many insurance and investment products, as well as passive structures (companies, trusts) through which controlling individuals are visible. CRS is tied to tax residency, not citizenship, so sound planning begins with honestly determined residency; attempts to conceal it do not work in the era of automatic exchange.
CRS 2.0 and CARF: The Next Phase
Transparency is expanding to digital assets. As of January 1, 2026, the updated standard (CRS 2.0) and a separate Crypto-Asset Reporting Framework (CARF) come into force: crypto exchanges and custodians will begin reporting on clients just like banks. The first exchanges will occur in 2027; dozens of jurisdictions have already joined, and in the EU this is formalized by the DAC8 directive. The idea of "crypto outside the tax authority's view" is becoming a thing of the past.
💡 CRS is an automatic annual exchange of account data tied to tax residency (unlike FATCA, which is based on citizenship). From 2026, CRS 2.0 and CARF extend the same logic to crypto. Planning is built on honestly determined residency; relying on secrecy does not work in this system.
