CRS and FATCA classification for Cayman crypto foundations and STAR trusts

Cayman’s CRS framework is the Tax Information Authority (International Tax Compliance) (Common Reporting Standard) Regulations, 2021 Revision, as amended in 2025. Most amendments commenced on 1 January 2026. The substituted return and filing provisions commence on 1 January 2027 and govern the 2026 reporting cycle. The calendar year being classified must therefore be distinguished from the year in which its return is filed. (CRS Regulations, regulations 6A and 9; 2025 Amendment Regulations, regulations 1, 5 and 6.)

The Organisation for Economic Co-operation and Development (OECD) standard helps explain the rules, but Cayman’s enacted Schedule supplies the operative requirements. Cayman expressly makes the OECD explanatory material and commentary integral to interpretation. That does not enact every optional OECD provision. (CRS Regulations, regulations 2 and 5.)

FATCA operates through the Cayman–US intergovernmental agreement (IGA) and Cayman’s United States of America Regulations, 2021 Revision. Its definitions and reporting dates must be checked independently. A foreign bank also applies the law governing its own due diligence. Its request should identify that basis, particularly where it treats an Investment Entity in a non-participating CRS jurisdiction as a Passive NFE. (Cayman–US IGA, articles 1 and 4(7); USA Regulations, regulation 2; CRS Schedule, VIII(D)(8).)

A foundation company’s constitution determines rights beyond the statutory defaults. It can cease to have members only under the statutory conditions, including continued supervision. Beneficiaries ordinarily lack rights concerning management and assets, but the constitution can expressly provide otherwise. Read the memorandum, articles, bylaws and reserved powers together. The Cayman Islands DAO analysis explains the governance background. (Foundation Companies Act, 2025 Revision, sections 7–8.)

A STAR trust can have persons, purposes or both as its objects. The trust instrument and Cayman’s special trust rules govern enforcement and trustee requirements. A person’s inability to enforce the trust as a beneficiary does not itself remove that person from a tax-reporting definition. The Guernsey purpose-trust analysis addresses a different governing-law framework; its structural conclusions should not be imported into Cayman. (Trusts Act, 2021 Revision, sections 99–102 and 105.)

Both the company and the trust are entities for CRS purposes. Establish each entity’s Cayman nexus, tax residences and any competing reporting residence. Incorporation, the location of management and trustee residence perform different legal functions. A foreign account does not by itself move the structure’s reporting obligations abroad. (CRS Regulations, regulation 2; CRS Schedule, VIII(E)(3); OECD CRS Commentary on Section VIII, paragraph 4.)

Start with all Financial Institution categories. Holding the structure’s own treasury is not, without more, a business of holding financial assets for others. The most relevant Investment Entity route requires both qualifying investment income and management by a specified Financial Institution. The manager must be a depository institution, custodial institution, specified insurance company or an Investment Entity conducting the relevant business for customers. A professional title or corporate registration alone is insufficient. (CRS Schedule, VIII(A)(3)–(6).)

Management requires discretionary authority over all or part of the assets. Bookkeeping, registered-office services, transaction execution under fixed instructions and administration without that authority do not establish this limb. A mandate covering only one portfolio can nevertheless satisfy it. Examine contracts, delegated powers and actual operation, including powers retained by trustees or exercised through corporate directors. (OECD CRS Commentary on Section VIII, paragraph 17; CRS FAQs, Section VIII(A), question 6.)

For this route, at least 50% of gross income must be attributable to investing, reinvesting or trading in Financial Assets or Relevant Crypto-Assets. Measure the shorter of the preceding three calendar years and the entity’s existence. For an established entity classified in 2026, the ordinary three-year window is 2023–2025. This is an income test, not a test of the percentage of treasury value invested. A new investment vehicle’s lack of income history does not justify an automatic NFE conclusion. (CRS Schedule, VIII(A)(6); CRS Regulations, regulation 6A; OECD CRS Commentary, paragraphs 18–20.)

Direct crypto and tokenised investments need different analysis

From 1 January 2026, the managed-entity income test expressly includes Relevant Crypto-Assets. It is therefore unsafe to reuse an older conclusion that a treasury holding direct crypto falls outside the test because crypto is not a Financial Asset. (2025 Amendment Regulations, regulation 19(f).)

The Financial Asset definition separately includes interests in Relevant Crypto-Assets, including derivatives such as futures and options. Ordinary custody of direct crypto does not itself turn the holding into such an interest. Tokenised shares, debt or fund interests must also be tested by the underlying rights. Some tokenised instruments can fall within both reporting frameworks. (CRS Schedule, VIII(A)(7); OECD CRS FAQs, Section VIII(A), questions 10–11.)

Cash, bank deposits, tokenised investments and direct crypto should have separate entries in the asset schedule. Reconcile interest, distributions, trading gains, lending or staking receipts and operating income to the ledger. Determine what each receipt represents before including it in an investment-income numerator. Central bank digital currencies and products satisfying the full Specified Electronic Money Product definition are excluded from Relevant Crypto-Assets and have their own CRS treatment. A “stablecoin” label does not prove those conditions. (CRS Schedule, VIII(A)(5), (9)–(14).)

The foundation’s two management variants

Where natural-person board members make investment decisions and the provider performs administration without discretion, that provider does not satisfy the managed-by limb. If no other Financial Institution category applies, classify the foundation as an NFE and test the available active categories.

When the proposed mandate takes effect, a qualifying entity manager with discretion, together with the required income proportion, can make the foundation an Investment Entity. The contract’s effective date and the income calculation matter. If either limb is absent, this particular route fails; other Financial Institution routes must still be considered. (CRS Schedule, VIII(A)(6); OECD CRS Commentary, paragraph 17.)

The STAR trust requires its own management assessment

The trust cannot simply copy the foundation’s initial result. Subject to the statutory exceptions and court authorisation, a STAR trustee must be or include a trust corporation. That definition includes appropriately licensed bodies and registered private trust companies. Determine whether the corporate trustee is itself a qualifying Financial Institution and has discretion over assets. If it does, the management limb may already be met. Hiring a separate investment manager would then change the operating arrangements without necessarily changing classification.

If the trustee has no relevant investment discretion, examine reserved powers and every other manager. A qualifying discretionary manager and the income threshold support Investment Entity status. If the requirements are not met and no other Financial Institution category applies, the trust follows the NFE analysis. (Trusts Act, sections 2 and 105; CRS Schedule, VIII(A)(6); OECD CRS Commentary, paragraphs 17–22.)

For an NFE relying on the ordinary active-business test, both conditions must hold: less than 50% of preceding-year gross income is passive, and less than 50% of the assets it held during that preceding year produce, or are held to produce, passive income. Spending investment returns on grants does not convert those returns into operating income. Cash can be held for passive-income production even when it earns no interest. Other active categories have their own requirements, including restrictions on investment vehicles and the 24-month limit for qualifying startups. (CRS Schedule, VIII(D)(9); OECD CRS Commentary, paragraphs 125–127.)

The non-profit Active NFE route requires all five elements:

1. Establishment and operation in the jurisdiction of residence, either exclusively for religious, charitable, scientific, artistic, cultural, athletic or educational purposes, or as a professional organisation, business league, chamber of commerce, labour, agricultural or horticultural organisation, civic league, or organisation operated exclusively for social welfare.
2. Income-tax exemption in the jurisdiction of residence.
3. No shareholders or members with a proprietary or beneficial interest in income or assets.
4. Legal or constitutional restrictions on private benefit, subject to the specified charitable-activity, reasonable-compensation and fair-value exceptions.
5. A binding dissolution rule directing all assets to government or another non-profit, or providing for government escheat.

Ecosystem support, a memberless company and a non-distribution clause do not by themselves establish all five elements. Actual activities and dissolution provisions need evidence. (CRS Schedule, VIII(D)(9)(h).)

Under Cayman CRS, this Active NFE category does not override an otherwise applicable Investment Entity classification. The Investment Entity exclusion covers specified other active categories, not paragraph (h). The OECD’s optional Qualified Non-Profit Entity category has not been added to Cayman’s enacted Non-Reporting Financial Institution list by the 2025 amendments. It cannot be claimed merely because it appears in the OECD consolidated standard. (CRS Schedule, VIII(A)(6), (B)(1); 2025 Amendment Regulations, regulation 19(g); OECD CRS Commentary, paragraphs 36quater–36sexies.)

The IGA’s Investment Entity definition covers an entity conducting specified investment activities as a business, or managed by an entity conducting those activities for customers. Its wording does not contain the same express 50% test as the CRS managed-entity definition. (IGA, article 1(1)(j).)

Cayman permits corresponding US Treasury or CRS definitions where their use would not frustrate the agreement’s purposes. The file should identify the selected definition, version and reason it is available. A Treasury-regulation analysis must apply that rule’s own income, management and financial-asset requirements. The 2026 CRS amendment should not silently become the FATCA analysis, nor should an old crypto description decide the treatment of every token or derivative. (IGA, article 4(7); USA Regulations, regulation 2(2)–(3); 26 CFR §1.1471-5(e)(4).)

Under the Treasury managed-entity route, routine corporate administration alone, such as bookkeeping or registered-office services, does not establish management. The selected rule also covers qualifying entity activities administering funds, money or financial assets; its text does not impose the CRS commentary’s express discretion prerequisite. The foundation proceeds to Non-Financial Foreign Entity (NFFE) tests only if neither that route nor another Financial Institution (FI) route applies. A qualifying FI trustee managing the assets, or a qualifying discretionary entity manager, supplies the management limb. The structure must also derive at least 50% of gross income from investing, reinvesting or trading in defined financial assets over the shorter of the preceding three calendar years and its existence, subject to startup rules and exclusions. Those assets include securities, specified commodities and derivatives. Direct crypto therefore needs its own asset classification; tokenised shares and debt are tested by their underlying rights. (26 CFR §1.1471-5(e)(4)(i)–(iv), (e)(5); 26 USC §475(c)(2), (e)(2); DITC FATCA Guidance Notes, sections 2.9.1–2.9.3.)

Non-profit treatment also differs. Cayman’s FATCA definition of Non-Financial Foreign Entity expressly includes an entity satisfying the IGA’s non-profit Active NFFE provision. Test every condition in Annex I, VI(B)(4)(j), including actual exclusive purposes, tax exemption, private-benefit restrictions and dissolution. This is a separate legal route from the CRS conclusion. (USA Regulations, regulation 2(1).)

For each management variant, therefore, record either the supported FATCA Financial Institution category and reporting arrangement, or the supported Active or Passive NFFE category. The facts described alone do not establish a qualifying manager, the income proportions or the full non-profit conditions.

There are two levels of account analysis. The bank or custodian maintains an account for the structure. If the structure is itself an Investment Entity, it can maintain financial accounts through equity or debt interests in the structure. These interests require their own due diligence; identifying the treasury’s external accounts does not complete that work. (CRS Schedule, VIII(C)(1), (4), (E)(1); IGA, article 1(1)(q), (t).)

For a Passive NFE trust, the controlling-person rules cover settlors, trustees, protectors, beneficiaries or classes, and other natural persons exercising ultimate effective control. Corporate role holders require the relevant natural-person analysis. A STAR enforcer’s powers must be examined as potential protection or ultimate-control powers. A purpose without named beneficiaries does not remove the settlor, trustee or control analysis. (CRS Schedule, VIII(D)(6); DITC CRS Guidelines v4.1, sections 3.D.II(b)–(c).)

For a trust that is a Financial Institution, the equity-interest analysis covers settlors, beneficiaries and natural persons exercising ultimate effective control. OECD guidance treats protectors as account holders and generally treats a discretionary beneficiary as an account holder in the year a distribution is paid or made payable. Indirect benefits can count. Cayman allows a corresponding distribution-year approach for discretionary beneficiaries of Passive NFE trusts only with appropriate procedures to identify distributions. Do not apply that exception to every trust role. (CRS Schedule, VIII(C)(4); OECD CRS Commentary, paragraphs 69–70; CRS FAQs, Section VIII(D), question 6; DITC CRS Guidelines, section 3.D.II(b).)

For the foundation, examine ownership, control through other means and the senior-management fallback where applicable. Cayman’s CRS controlling-person materials use a 10% ownership or voting threshold, but ownership is only one route to control. Where a foundation functions like a trust, equivalent-role analysis matters; where it is an Investment Entity, the OECD commentary also applies the trust equity-interest approach to equivalent foundation arrangements. When relying on AML/KYC for a new entity account, the commentary expressly requires foundation founders to be treated as controlling persons. Memberlessness cannot justify an empty reporting analysis. These tests are separate from corporate beneficial-owner register filings. (AML Regulations, 2025 Revision, regulation 2; OECD CRS Commentary, paragraphs 69 and 133–137.)

FATCA must separately identify US reportable connections. The IGA controlling-person definition and FI-trust equity definition serve different functions. The Cayman entity form also allows a permitted US-regulations Substantial US Owner alternative for a Passive NFFE. That FATCA choice does not replace the CRS controlling-person test. Check US citizenship as well as tax residence, and apply the Specified US Person exclusions. Under the IGA route, a relevant account can be reportable when held by a Specified US Person or a Passive NFFE with a US controlling person, subject to the applicable due-diligence rules. (IGA, article 1(1)(t), (y), (aa)–(bb), (hh), article 4(7), Annex I V.B(3); DITC Entity Self-Certification v3.0, section 3.3(e).)

As at 6 November 2026, the templates of Cayman’s Department for International Tax Cooperation (DITC) are Entity Self-Certification v3.0 and Individual Self-Certification v2.0, both issued on 14 September 2026. The entity form separates FATCA and CRS and contains Part IV for controlling persons. Equivalent forms may be used, but statutory minimum information remains mandatory. For new CRS accounts, obtain a valid self-certification on or before opening, subject to the narrow statutory exception. Collect all tax residences, applicable taxpayer identification number information and the required identity details. (DITC Entity Self-Certification v3.0 and Individual Self-Certification v2.0; CRS Regulations, regulation 7; CRS Schedule, VII Abis; DITC June 2026 Updates Bulletin.)

A qualifying trustee-documented trust is a Non-Reporting Financial Institution only to the extent that the qualifying trustee reports all required information. Establish the trustee’s status, undertaking and reporting process. Under Cayman CRS, the trust has its own DITC registration and reporting identity. Under FATCA, the qualifying trustee reports under the trustee-documented arrangement; the trust does not obtain its own Global Intermediary Identification Number merely for that status. A foundation cannot use a trust-specific route. Ordinary outsourcing also leaves the institution responsible and requires continued access to records. (CRS Schedule, VIII(B)(1)(e); DITC CRS Guidelines, section 2.B.IV(a); IGA, Annex II, IV(A); IRS FATCA Compliance Legal FAQs, Registration Q3; USA Regulations, regulation 17.)

Allocate the calendar to the board or trustee, the reporting provider and the authorised signatory:

• 2025 reporting: the official 2026 calendar set 31 July 2026 for CRS and FATCA reports and the CRS declaration, and 15 September 2026 for the CRS compliance form. These are past deadlines, not the timetable for 2026 data.
• 2026 CRS classification and registration: an entity becoming a Cayman Financial Institution during 2026 generally registers by 31 January 2027. The DITC extension to that date covers Cayman principal-point-of-contact information and the date FI status began; it did not extend every registration obligation.
• 2026 CRS reporting: returns, the declaration and the compliance form are due by 30 June 2027. Nil-reporting requirements must also be addressed. The amended provisions refer to each Cayman Financial Institution, so a non-reporting label alone should not be used to bypass the relevant administrative analysis.
• 2026 FATCA reporting: the statutory return date remains 31 July 2027. Cayman does not make a FATCA nil return mandatory. Notify DITC by 30 April in the first calendar year in which reporting obligations must be complied with. Where regulation 4(2)’s business-commencement rule applies, apply for registration with the US Internal Revenue Service as soon as possible and within 30 days after that commencement.
• Evidence retention: preserve CRS due-diligence information and steps for six years from the end of the relevant year. The FATCA due-diligence rule likewise runs from year-end. Evidence for 2026 must therefore remain available through 31 December 2032.

(2025 Amendment Regulations, regulations 3–6; DITC PPoC extension, 21 January 2026; DITC June 2026 Updates Bulletin; USA Regulations, regulations 4, 6(2)(b), 8 and 14.)

The CRS transition for certain role information on accounts maintained at 31 December 2025 is limited to electronically searchable information for the 2026 and 2027 reporting periods. It does not postpone all new due diligence or all reporting fields. Accounts treated as Financial Accounts solely because of the amendments use 31 December 2025 and 1 January 2026 as the pre-existing/new-account cut-offs; those dates do not reset the status of every existing bank account. (CRS Schedule, VIII(C)(9)(a), (10), X(B).)

Review the proposed discretionary mandate before it takes effect. Recalculate under the applicable measurement period when investment income, assets or operating activities change. A manager’s appointment can complete the management limb during the year; it does not require waiting for the next annual filing. Conversely, a portfolio change does not erase the prescribed historical income window.

Record the effective date, changed facts and separate CRS and FATCA conclusions. Update the certification given to each bank or custodian promptly. The DITC entity form undertakes to supply an updated certification within 30 days after a relevant change. CRS registered-information changes are generally notified within 30 days; the FATCA regulation requires notification of specified changes immediately. Distinguish these from account due-diligence remediation periods. (CRS Regulations, regulation 8; USA Regulations, regulation 14(5); DITC Entity Self-Certification v3.0, declaration.)

Own-treasury transactions do not alone establish a business providing crypto exchange services for customers. Cayman CARF and EU DAC8 require their own provider and territorial analysis. A foundation can nevertheless be a reportable customer, and managed Investment Entity status does not automatically make it an excluded CARF user. The international-platform CARF and DAC8 analysis addresses those provider obligations. (Cayman CARF Regulations 2025, Schedule IV(B)(1), (E)(1)(f); Directive 2011/16/EU as amended by Directive 2023/2226, Annex VI.)

Any CRS relief for duplicate gross-proceeds reporting is confined to the enacted conditions, including reporting by the same Financial Institution under CARF. It does not excuse classification or all account reporting. (CRS Schedule, I(F).)
