tax/CRS-FATCA

Who is caught

The instruments indexed here implement the Cayman Islands' international tax co-operation regimes: automatic exchange of financial account information (CRS and the US FATCA intergovernmental agreement), Country-by-Country Reporting (CbCR), the Crypto-Asset Reporting Framework (CARF), the economic substance regime, and the underlying framework for executing foreign information requests. Each regime defines its own in-scope population, so an entity may fall within several at once.

• CRS: Cayman Financial Institutions, distinguishing Reporting Financial Institutions from Non-Reporting Financial Institutions, being institutions resident in the Islands or Cayman branches of foreign institutions (including funds, trusts, insurance companies, and depository and custodial institutions), under the Common Reporting Standard Regulations (2021 Revision) and the 2025 Amendment Regulations.
• FATCA: Persons carrying on business in the Cayman Islands as a custodial institution, depository institution, investment entity or specified insurance company, split into Reporting and Non-Reporting/Registered Deemed-Compliant Financial Institutions, under the United States of America Regulations (2021 Revision) and the 2013 Cayman-US IGA.
• CbCR: Constituent Entities of MNE Groups resident in the Cayman Islands (incorporated or established there, having their place of effective management there, or subject to financial supervision there) where the MNE Group's total consolidated group revenue is at least US$850 million, under the Country-by-Country Reporting Regulations, 2017.
• CARF: Cayman Reporting Crypto-Asset Service Providers, broadly entities or individuals that as a business effectuate exchange transactions in relevant crypto-assets (including exchanges, brokers, dealers, trading platforms and crypto-asset ATM operators) resident in or operating a branch in the Islands, under the Crypto-Asset Reporting Framework Regulations, 2025.
• Economic substance: All Cayman Islands entities (companies, LLCs, LLPs, partnerships and exempted limited partnerships), with additional substance obligations for those that are relevant entities carrying on a relevant activity, under the International Tax Co-operation (Economic Substance) Act (2026 Revision).
• Information requests: Banks, other financial institutions, nominees, trustees and other persons holding relevant records, and persons who are themselves the subject of a request, may be compelled to produce information when the Tax Information Authority executes a request under a scheduled agreement, under the Tax Information Authority Act (2021 Revision) and the Tax Information Authority Regulations (2013 Revision).

Key duties

The regimes share a common shape: a one-off registration/notification to the Tax Information Authority (administered through DITC), ongoing due diligence and self-certification, an annual return or report, change notifications, and multi-year record retention. Filings are made through the DITC Portal in the form and manner the Authority specifies.

CRS filings and deadlines

• Registration: Each Cayman Financial Institution (other than an exempted body) must register with the Authority; the CRS Guidelines state registration by the next 30 April after the entity becomes an FI, and the 2025 Amendment Regulations require an entity that became an FI in 2025 to register by 30 April 2026 and new FIs thereafter by 31 January following the relevant year.
• Policies and due diligence: FIs must establish, implement and maintain written CRS policies and procedures, identify each jurisdiction of tax residence of account holders and controlling persons, and collect a valid self-certification for new accounts on or before account opening.
• Annual return: FIs must make an annual CRS return (or nil return) with a declaration; the CRS Guidelines give a 31 July filing date, and the 2025 Amendment Regulations move the return and compliance form to 30 June of the following year once the replacement regulation 9 takes effect on 1 January 2027.
• Compliance form: All FIs with CRS reporting obligations, including Trustee Documented Trusts, must submit the annual CRS Compliance Form via the DITC Portal by 15 September, per the DITC FAQs and guidance.
• Change notice: FIs must notify the Authority of any change to previously notified information, within thirty days of the change under the 2025 Amendment Regulations.
• Records: CRS due diligence records must be kept for at least six years from the end of the relevant year.

FATCA

• IRS registration: Reporting and Registered Deemed-Compliant Financial Institutions must complete applicable IRS FATCA registration; the Regulations set an original deadline of 31 December 2014 or, for later entrants, within 30 days of commencing business.
• Due diligence and reporting: Reporting Financial Institutions must apply identification procedures to determine US Reportable Accounts, report on them to the Competent Authority, and obtain TINs for US specified persons (from 1 January 2017 for pre-existing accounts and 1 July 2014 for new accounts).
• Agents: An FI appointing a third-party agent remains responsible for the agent's performance and must retain access to the underlying records for production to the Competent Authority.

CbCR

• Notification: Constituent Entities resident in the Islands must notify the Authority of their reporting status through a single, centralised notification made by the Reporting Entity before the end of the relevant fiscal year.
• Report: An Ultimate Parent Entity or Surrogate Parent Entity resident in the Islands must file the Country-by-Country Report in the standard template within twelve months of the last day of the reporting fiscal year, via the DITC Portal.
• Records: Constituent Entities must retain relevant records for six years.

CARF

• Registration: Pre-existing CRCASPs (other than exempted bodies) must register with the Authority by 30 April 2026; those becoming CRCASPs later must register by 31 January following the relevant year.
• Due diligence and self-certification: CRCASPs must apply the CARF due diligence procedures, collect self-certifications from new users on establishing the relationship, and from pre-existing users within twelve months of the Regulations coming into force (by 31 December 2026).
• Returns and change notices: CRCASPs must submit annual returns, nil returns or declarations (first reporting due 30 June 2027 for the 2026 year) and file a change notice within thirty days of any change in circumstances.

Economic substance

• Annual notification: Every entity must annually notify the Authority whether it carries on a relevant activity and, if so, whether it is a relevant entity, in the form and at the time the Authority specifies.
• ES report: A relevant entity carrying on a relevant activity must satisfy the economic substance test and submit an ES report no later than twelve months after the last day of its financial year.
• Records: Relevant entities must retain supporting records for six years and provide additional information or make records available for inspection when reasonably required.

Exemptions and carve-outs

The instruments provide carve-outs that either remove entities from a regime or reduce their obligations.

• CRS exempted bodies: CIMA, Governmental Entities and certain CIMA or government pension funds are treated as exempted bodies and are carved out of some notification duties under the CRS Regulations and the 2025 Amendment Regulations.
• CRS Non-Reporting FIs: Non-Reporting Financial Institutions are distinguished from Reporting FIs, and an Investment Entity without financial accounts under Schedule 1 can indicate this on registration, which disables CRS reporting functionality.
• FATCA deemed-compliant and exempt: Non-Reporting Cayman Islands Financial Institutions, including deemed-compliant institutions and exempt beneficial owners falling within Annex II of the IGA (or otherwise qualifying under US Treasury Regulations), are not subject to the reporting obligations of Reporting Financial Institutions.
• CbCR revenue threshold: MNE Groups with total consolidated group revenue below US$850 million fall outside CbCR; entities that are neither Ultimate nor Surrogate Parent Entity have only a reduced obligation to identify the actual Reporting Entity.
• Economic substance reduced test: Pure equity holding companies are subject to a reduced economic substance test, and high-risk intellectual property businesses face a rebuttable presumption of non-compliance rather than an exemption; this is a lighter obligation, not a carve-out from the regime.

Enforcement and penalties

Enforcement powers and penalties differ by instrument, and the summaries attribute specific figures to specific regimes; they are kept separate below.

Economic substance

• Late ES report: Under the International Tax Co-operation (Economic Substance) Act (2026 Revision), a relevant entity that fails to submit its ES report on time is liable to an automatic penalty of $5,000 plus $500 for each day the failure continues, payable within 30 days of notice. The Act also creates offences for providing misleading information and offences by officers of a body corporate.

CRS

• Administrative penalties: The CRS Enforcement Guidelines describe the penalty framework under Regulation 24 of the CRS Regulations: a Primary Penalty of up to $50,000 for a body corporate (or individuals forming part of an unincorporated Cayman Financial Institution), up to $20,000 for other offenders, and a Continuing Penalty of $100 per day for ongoing contraventions, applied via breach notices and penalty notices with a right of appeal to a court within 60 days.
• Compliance form default: Failure to submit the CRS Compliance Form by the 15 September deadline puts the FI in breach of the CRS Regulations and results in an automatic administrative penalty, per the DITC FAQs.
• Offences: The CRS Regulations create offences including false self-certification, providing inaccurate information, unauthorised access to confidential information, tampering and hindering, with imputed liability for directors and officers; criminal offences are referred to the Director of Public Prosecutions rather than dealt with administratively.

CbCR and CARF

• CbCR: The Country-by-Country Reporting Regulations, 2017 create offences and administrative penalties, including daily default penalties, for non-compliance, tampering, hindering the Authority or entering into avoidance arrangements; a reasonable excuse defence is available and penalty decisions can be appealed.
• CARF: Part 4 of the Crypto-Asset Reporting Framework Regulations, 2025 allows the Authority to impose penalties for failure to submit returns, declarations or required information (in some cases without first issuing a breach notice), alongside criminal offences and director/officer liability, with a right of appeal.

Information-request offences

• Tampering: Under the Tax Information Authority Regulations (2013 Revision), a recipient of a Notice to Produce Information who alters, destroys or hides information is liable to a fine of $10,000 and up to 2 years' imprisonment under section 24(1) of the Tax Information Authority Law.
• Confidentiality breach: Breaching the confidentiality obligations attaching to a Notice to Produce Information or a Notice of Request is subject to a fine of $1,000 and up to 6 months' imprisonment under section 24(2) of the Tax Information Authority Law. The Tax Information Authority Act also contains an offence for providing false or misleading information.
