Common Reporting Standard (CRS)

August 31, 2024 Taxation Regulation

The Common Reporting Standard sets due-diligence and reporting rules for exchanging financial-account information among participating tax jurisdictions.

On this page

The Common Reporting Standard (CRS) is an OECD-developed standard under which participating jurisdictions require reporting financial institutions to identify reportable financial accounts, send specified information to their local tax authority, and support automatic exchange with relevant partner jurisdictions.

CRS affects account onboarding, tax-residence self-certifications, entity classification, controlling-person review, annual reporting, and data corrections. It does not set income-tax rates or determine whether an account balance is taxable.

Key Takeaways

CRS is a standard for financial-account due diligence and reporting within the broader Automatic Exchange of Information process.
Reporting generally flows from a financial institution to its local tax authority, then between tax authorities under active exchange arrangements.
The institution must classify both the account and the account holder; some entity accounts also require review of controlling persons.
Tax residence, not citizenship alone, is central to CRS classification, subject to each jurisdiction’s implementation and residence rules.
CRS and FATCA can apply to the same customer relationship but use different legal definitions, forms, and reporting logic.

Who Participates in CRS Reporting

The CRS process involves three main groups:

Participant	Main responsibility
Reporting financial institution	Apply due diligence, collect documentation, classify accounts, and report specified data
Account holder or controlling person	Provide accurate identity, entity-status, and tax-residence information and update it when circumstances change
Tax authority	Receive domestic reports, validate and exchange information, and use received data under applicable law

Whether an organization is a reporting financial institution depends on local law and CRS definitions. Banks, custodial institutions, specified investment entities, and certain insurance companies may fall within scope, while exemptions and nonreporting categories may apply.

How CRS Classifies an Account

CRS due diligence asks a sequence of questions rather than treating every foreign account alike:

Is the institution and account within scope under local implementation?
Is the account holder an individual or an entity?
Where is the account holder tax-resident?
If the holder is an entity, is it a financial institution or a nonfinancial entity?
If a passive nonfinancial entity is involved, who are its controlling persons and where are they tax-resident?
Is the account reportable to one or more jurisdictions under active exchange relationships?

Documentary evidence, self-certifications, indicia, reasonableness checks, and changes in circumstances can affect the conclusion. The terms used by a bank’s commercial onboarding system may not map perfectly to the legal CRS classification.

Information Commonly Reported

Subject to the applicable rules, a CRS report may contain:

name, address, jurisdiction of residence, taxpayer identification number, and date of birth where relevant;
account number and reporting financial institution details;
account balance or value at the reporting period end or account closure information; and
specified interest, dividends, other income, or gross proceeds credited to or associated with the account.

These are reporting fields, not final measures of taxable income. Gross proceeds do not subtract basis, and an account value does not show ownership disputes, currency risk, restrictions, or tax due.

Account-Classification Example

An individual who lives and is tax-resident in Country B opens a brokerage account in Country A. The broker obtains a self-certification, checks it against onboarding information, and identifies Country B as a reportable jurisdiction. If the broker and account are within scope and the exchange relationship is active, the broker reports specified account data to Country A’s tax authority. Country A’s authority can then exchange the data with Country B’s authority.

If the investor later changes tax residence, the broker may need updated documentation and a revised reporting classification. Merely changing a mailing address does not by itself resolve tax residence.

CRS vs. FATCA

Feature	CRS	FATCA
Source	OECD-developed international standard implemented by participating jurisdictions	U.S. statutory framework implemented through U.S. rules and intergovernmental arrangements
Primary status connection	Tax residence in a reportable jurisdiction	Specified U.S. status or ownership connection
Reporting route	Usually institution to local authority, followed by jurisdiction-to-jurisdiction exchange	Route depends on the applicable FATCA model and institution status
Scope	Multilateral network of participating jurisdictions	U.S.-centered framework with global institutional reach
Interchangeable?	No	No

An institution may ask for both CRS and FATCA certifications. Completing one does not automatically establish status under the other.

Common Mistakes and Limitations

Equating residence with nationality. A passport, place of birth, mailing address, and tax residence may point to different jurisdictions and need separate analysis.

Ignoring entity look-through. A passive entity can require controlling-person review even when the entity itself is not tax-resident where a controlling person lives.

Assuming every jurisdiction exchanges with every other. Participation, domestic commencement, active exchange relationships, and reportable years must be checked.

Treating a self-certification as permanently valid. A change in address, ownership, tax status, or other circumstances may make prior documentation unreliable.

Reading reported proceeds as profit. Tax authorities may receive gross financial information that requires basis, expense, sourcing, and local-law analysis.

What to Verify

The jurisdiction’s current CRS legislation, guidance, and reporting calendar.
Institution and account classification, including exclusions or exemptions.
Tax-residence self-certifications, taxpayer identification numbers, and controlling-person records.
Reportable jurisdictions and active exchange relationships for the relevant year.
Data reconciliation, corrections, notifications, and separate taxpayer filing duties.

FAQs

Does CRS create a tax on foreign accounts?

No. CRS is an information-reporting standard. Any tax liability depends on the taxpayer’s jurisdiction, income, ownership, basis, treaty position, and other applicable rules.

Why does a bank ask for a tax-residence self-certification?

The institution may need the information to classify the account and determine whether it is reportable under CRS, FATCA, or local law. The customer should provide accurate information and update it when circumstances change.
