CRS (Common Reporting Standard)

Also known as: Common Reporting Standard, OECD CRS, Automatic Exchange of Information

Quick answer

The Common Reporting Standard is the OECD framework for automatic exchange of financial-account information between participating tax authorities. Financial institutions apply domestic due-diligence and reporting rules to identify relevant account holders and tax residences. Participation and activated exchange relationships must be checked for the relevant reporting year; a global membership count does not establish a particular exchange.

Reference:Common Reporting Standard

HMRC publishes the jurisdictions participating in its CRS arrangements for each reporting year, including a separate 2026 list. These lists concern tax-information exchange and do not determine whether a person's income is exempt from tax.

CRS and the US FATCA framework are separate. A financial institution may request tax-residence self-certification under the applicable rules. Reportable information and exchange destinations depend on the legal arrangements, rather than the person's passport alone.

FATCA

FATCA creates foreign financial-account reporting obligations for financial institutions and certain taxpayers. Under the IRS rules checked in 2026, individuals qualifying as living abroad generally file Form 8938 above $200,000 at year-end or $300,000 during the year; joint-filer thresholds are $400,000 and $600,000 respectively. Filing obligations and exceptions depend on the person's circumstances.

FBAR

FBAR is the foreign financial-account report filed on FinCEN Form 114. Under the rules checked in 2026, a US person generally must file when reportable foreign accounts exceed $10,000 in aggregate at any time during the calendar year. Financial interest or signature authority can trigger reporting. FBAR is separate from the income-tax return and Form 8938.

Tax Residency

Tax residency is a domestic-law status used to determine a person's tax obligations. It is distinct from citizenship and permission to live in a country. Presence, homes, work and other ties can matter. A person can meet more than one country's domestic rules; an applicable tax treaty may resolve residence for treaty purposes.

Tax Treaty

A tax treaty is an agreement between jurisdictions that can allocate taxing rights, reduce specified taxes and provide relief from double taxation. Entitlement depends on the treaty's text, residence and other conditions. Treaties and protocols have their own effective dates; signing a treaty is not the same as bringing it into force.
