tax/CRS-FATCA

Who is caught

These instruments implement the Cayman Islands' international tax transparency regimes, all administered by the Tax Information Authority through the Department for International Tax Cooperation (DITC). They apply to different populations depending on the standard, and a single entity can fall within several at once.

• CRS: The Common Reporting Standard Regulations apply to Cayman Financial Institutions, meaning institutions resident in the Cayman Islands or Cayman branches of foreign institutions, distinguishing Cayman Reporting Financial Institutions from Non-Reporting Financial Institutions and exempted bodies.
• FATCA: The US Regulations and the underlying 2013 US-Cayman intergovernmental agreement apply to any person carrying on business in the Cayman Islands as a custodial institution, depository institution, investment entity or specified insurance company (a Financial Institution).
• CbCR: The Country-by-Country Reporting Regulations apply to Constituent Entities of MNE Groups resident in the Cayman Islands (incorporated or established there, effectively managed there, or subject to financial supervision there) where the MNE Group's total consolidated revenue is US$850 million or more.
• CARF: The Crypto-Asset Reporting Framework Regulations apply to Cayman Reporting Crypto-Asset Service Providers, broadly crypto-asset service providers resident in or with a branch in the Islands, including exchanges, brokers, dealers and operators of crypto-asset ATMs.
• Economic substance: The International Tax Co-operation (Economic Substance) Act applies to all Cayman entities (companies, LLCs, LLPs, partnerships and exempted limited partnerships), with additional obligations for relevant entities carrying on a relevant activity.
• Information exchange framework: The Tax Information Authority Act and its forms regulations reach banks, other financial institutions, nominees, trustees and fiduciaries, and persons who are themselves the subject of a request, when the Authority executes an incoming treaty request.

Key duties

The recurring duties across these regimes follow a common pattern: register or notify the Authority, carry out due diligence, file annually, and retain records for six years. Deadlines differ by regime, and several were reset by the 2025 CRS amendments and the new CARF regime.

Registration and notification

• CRS registration: Each Cayman Financial Institution (other than an exempted body) must give the Authority an information notice with prescribed details including a principal point of contact, and a change notice if that information changes. Under the 2025 amendments, an entity that became an FI in a calendar year must register by the next 31 January (with entities that became FIs in 2025 registering by 30 April 2026), and change forms are due within thirty days of a change.
• CARF registration: An entity or individual that was a CRCASP before commencement must register by 30 April 2026; those becoming CRCASPs afterwards must register by 31 January following the year they became a CRCASP, with change notices within thirty days.
• CbCR notification: A Constituent Entity resident in the Islands must notify the Authority of its status (Ultimate Parent Entity, Surrogate Parent Entity, or otherwise the identity of the actual Reporting Entity) before the end of the relevant fiscal year; DITC guidance requires a single centralised notification per MNE Group made by the Reporting Entity.
• Economic substance notification: Every Cayman 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 specified.
• FATCA registration: Reporting and Registered Deemed-Compliant Financial Institutions must complete the applicable IRS FATCA registration.

Annual filings

• CRS return and compliance form: Cayman Reporting Financial Institutions must make an annual CRS return (or nil return). Per DITC guidance the annual CRS Compliance Form is due by 15 September. The 2025 amendments introduce a dual filing of an annual return plus a compliance form due by 30 June of the following year once the replacement of regulation 9 takes effect on 1 January 2027.
• CbCR report: A Reporting Entity resident in the Islands (UPE or SPE) must file a Country-by-Country Report within twelve months of the end of the relevant fiscal year, in the standard template, via the DITC Portal.
• CARF return: CRCASPs must submit annual returns, nil returns or declarations, with first reporting due 30 June 2027 for the 2026 calendar year.
• Economic substance report: A relevant entity carrying on a relevant activity must submit an ES report no later than twelve months after the last day of its financial year.
• FATCA report: Reporting Financial Institutions must report US Reportable Accounts to the Competent Authority for onward exchange with the IRS.

Due diligence, self-certification and records

• Written policies and procedures: CRS Reporting FIs and CARF CRCASPs must establish, maintain and implement written policies and procedures to satisfy the due diligence and reporting requirements and to identify each jurisdiction of tax residence.
• Self-certification: For CRS new accounts, a valid current self-certification (including TIN and date of birth, which DITC treats as effectively mandatory) must be collected on or before the account is opened. CARF requires self-certifications from new users when the relationship is established and from pre-existing users within twelve months of commencement.
• Record retention: CRS, FATCA-related, CbCR, CARF and economic substance records must generally be retained for six years.
• Information requests: Entities must provide additional information or make records available for inspection when the Authority reasonably requires it, within the time it specifies.

Filings and notifications under CRS, FATCA, CbCR, CARF and economic substance are made through the DITC Portal in the form and manner the Authority specifies, and technical guidance sets out the required XML schemas, file formats and validation rules.

Exemptions and carve-outs

The regimes carve out defined categories rather than granting general exemptions. The main carve-outs relate to non-reporting status and, for CbCR, a revenue threshold.

• CRS exempted bodies: CIMA, Governmental Entities and certain Pension Funds are treated as exempted bodies carved out of some notification duties, and Non-Reporting Financial Institutions are distinguished from Reporting Financial Institutions.
• FATCA non-reporting entities: Non-Reporting and Registered Deemed-Compliant Financial Institutions are distinguished from Reporting Financial Institutions; entities relying on non-reporting status must fall within a category in Annex II of the IGA or otherwise qualify as a deemed-compliant FFI or exempt beneficial owner.
• CbCR threshold: CbCR obligations arise only for MNE Groups with total consolidated group revenue of US$850 million or more, so smaller groups fall outside the reporting requirement.
• Economic substance reduced test: Pure equity holding companies are subject to a reduced economic substance test rather than a full test; high-risk intellectual property businesses face a rebuttable presumption of non-compliance. All entities, including those out of scope of the substance test, must still file the annual notification.
• CARF exempted body: An entity or individual that is an exempted body is not subject to the CARF registration requirement.

Note that the CRS undocumented-account treatment is a narrow classification, not an exemption from reporting, and applies only where specific conditions are met.

Enforcement and penalties

Enforcement combines automatic and administrative penalties with criminal offences. The amounts and mechanics differ by regime.

• Economic substance: 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.
• CRS administrative penalties: Under Regulation 24 of the CRS Regulations, the Authority may impose 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, applied through breach notices, penalty notices, representations and appeal rights.
• CRS Compliance Form: Failure to submit the CRS Compliance Form by the 15 September deadline puts the FI in breach and results in an automatic administrative penalty.
• CbCR: The CbCR Regulations 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 and appeal rights apply.
• CARF: The CARF Regulations establish criminal offences (including false self-certification, obstruction, tampering and unauthorised access), director and officer liability, and a civil administrative penalty regime; DITC guidance notes the Authority may impose penalties for reporting failures without first issuing a breach notice.
• FATCA: Financial Institutions and their directors and officers may be liable to offences for failure to comply with the US Regulations.
• Information notices: Under the Tax Information Authority Act framework, altering, destroying or hiding information required by a Notice to Produce carries a fine of $10,000 and up to two years' imprisonment, and breaching the associated confidentiality carries a fine of $1,000 and up to six months' imprisonment; providing false or misleading information is an offence.

CRS enforcement guidance sets out how the Authority weighs seriousness, intent or negligence, post-breach conduct and compliance history in deciding penalties, with a right of appeal to a court within 60 days of a Penalty Notice and interest on unpaid amounts; criminal offences are referred to the Director of Public Prosecutions.
