The Common Reporting Standard (CRS) is the OECD's framework for automatic annual exchange of financial account information between tax authorities in participating countries. Introduced from 2017, it requires banks and other financial institutions in over 100 jurisdictions to identify the tax residency of account holders and automatically report account details to the relevant home-country tax authority — without any request being necessary.
Background
CRS emerged from sustained international political pressure following the 2008 financial crisis and a series of high-profile offshore tax scandals — including the UBS affair in the United States and the subsequent FATCA legislation. The G20 mandated the OECD to develop a global standard for automatic exchange of financial information, leading to the publication of the CRS in 2014 and the first exchanges of data in 2017.
Before CRS, tax authorities could only obtain information about their residents' foreign accounts through formal treaty-based exchange of information on request — a slow, bilateral and largely reactive process. CRS replaced this with a systematic, automatic, annual exchange covering all participating jurisdictions simultaneously. The practical effect was a fundamental shift in the offshore banking landscape: accounts that had previously been effectively opaque to home-country tax authorities became automatically visible.
How It Works
Financial institutions — banks, custodians, investment funds, insurance companies, trust companies — identify the tax residency of all account holders using self-certification forms (similar to the US W-9/W-8 process). Existing accounts above de minimis thresholds are reviewed; new accounts are certified at opening.
For individual accounts above USD 1 million (high-value accounts), financial institutions conduct enhanced due diligence including a paper record review, electronic search and relationship manager inquiry. Lower-value individual accounts and entity accounts have different thresholds and procedures.
Reportable information includes: account holder name and address, jurisdiction of tax residence, TIN (Tax Identification Number), date and place of birth (for individuals), account number, account balance at year-end, total gross interest/dividends/proceeds paid during the year.
Financial institutions in each participating jurisdiction submit the collected information to their local tax authority — for example, a Jersey bank reports to the Jersey Comptroller of Revenue, a Singapore bank reports to IRAS.
Each jurisdiction's tax authority automatically exchanges the information with the tax authorities of the account holders' countries of tax residence. The exchange is bilateral — Jersey sends UK account holder data to HMRC; HMRC sends Jersey-resident account holder data back to Jersey.
The home-country tax authority receives the data and can match it against domestic tax returns. Where foreign income has not been declared, the authority has the information to initiate enquiries or investigations.
What Is Reported
| Information Category | Individuals | Entities (Companies, Trusts) |
|---|---|---|
| Identity | Name, address, date and place of birth | Entity name, address, jurisdiction of incorporation |
| Tax identification | TIN in jurisdiction of tax residence | Entity TIN; controlling persons' TINs |
| Account details | Account number, financial institution name | Account number, financial institution name |
| Balance | Year-end account balance or value | Year-end account balance or value |
| Income | Total gross interest, dividends, proceeds of sales/redemptions, other income paid or credited | Same; attributed to controlling persons for Passive NFEs |
| Controlling persons | N/A (individual is the account holder) | Beneficial owners / controlling persons identified and reported — including settlors, trustees, protectors and beneficiaries of trusts |
Participating Jurisdictions
Over 100 jurisdictions participate in CRS. All major offshore financial centres have committed to and implemented CRS. The notable non-participant is the United States, which operates its own equivalent framework (FATCA) but does not send information under CRS — an asymmetry frequently noted by other jurisdictions.

CRS and Offshore Structures
CRS fundamentally changed the information landscape for offshore financial accounts. Several specific implications for common offshore arrangements are worth understanding:
Account balances, interest, dividends and proceeds are reported annually to the account holder's home-country tax authority. There is no threshold below which offshore accounts avoid reporting (above the de minimis due diligence thresholds).
Professional trustees in CRS jurisdictions must report information on the trust's settlor, trustees, protector, beneficiaries and any other controlling persons. This information is exchanged with the relevant foreign tax authorities — the trust's private nature from external parties does not extend to tax authorities.
Companies that are "Passive Non-Financial Entities" — broadly, holding companies receiving passive income — are look-through entities under CRS. The financial institution must identify and report the controlling persons (beneficial owners) of such companies, not just the company itself.
Funds are typically classified as financial institutions under CRS and must conduct their own due diligence on investors and report relevant account information. Cayman funds administered by Cayman fund administrators have been within scope since 2017.
Common Misconceptions
✗ Myth
CRS only affects very large accounts.
✓ Fact
CRS reporting applies to all reportable accounts above de minimis thresholds. The enhanced due diligence threshold (USD 1m) relates to the depth of the review process, not to whether reporting occurs.
✗ Myth
CRS does not affect trusts — only bank accounts.
✓ Fact
Trusts administered by professional trustees in CRS jurisdictions are fully within scope. Settlors, trustees, protectors and beneficiaries are all reportable persons.
✗ Myth
Moving to the UAE makes offshore accounts invisible under CRS.
✓ Fact
CRS reporting is based on the account holder's current jurisdiction of tax residence. If an account holder has genuinely become UAE tax resident, their accounts will be reported to the UAE — which has no income tax but does receive the data. The key is genuine tax residency change, not mere relocation.
✗ Myth
US accounts are invisible to foreign tax authorities because the US doesn't participate in CRS.
✓ Fact
The US operates FATCA — its own reporting regime — and has bilateral information exchange agreements with most major jurisdictions. US account information is not entirely opaque to foreign authorities, though the US does receive substantially more than it sends under current arrangements.
