Legal structures
| Local name | Abbreviation | Description |
|---|---|---|
| International Company | IC | Incorporated under the International Companies Act 1981-82 and registered with the Financial Supervisory Commission (FSC); the primary offshore vehicle widely used for cross-border trade, holding, and asset management. Only one director and one shareholder required (same person or corporate entity permitted); 100% foreign ownership allowed; no minimum share capital; register of directors and members is private (not publicly accessible); registered agent appointment mandatory. Subject to Cook Islands corporate income tax (20% on profits) for companies incorporated after December 2019 (previously exempt for a transitional period ending 2022). Annual return must be filed with the FSC. Closest US equivalent: C-Corp. |
| Domestic Company Limited by Shares | Ltd. | Incorporated under the Companies Act 2017 and registered with the Cook Islands Registry Services (Ministry of Justice); carries separate legal personality with liability capped at the amount unpaid on members’ shares. The standard domestic trading vehicle for Cook Islands-based operations. Must maintain a registered office in the Cook Islands; annual return filed electronically via registry.justice.gov.ck. Governed by a board of directors; constitution (model or customised) filed with the Registrar. Closest US equivalent: Private Corporation / C-Corp. |

Used primarily for non-profit, charitable, or professional association purposes. Registered with the Cook Islands Registry Services (Ministry of Justice). Closest US equivalent: Nonprofit Corporation. |
| Limited Liability Company | LLC | Formed under the Limited Liability Companies Act 2008 and registered with the Financial Supervisory Commission (FSC); blends corporate limited liability with partnership-style flexibility. No share capital concept — members hold membership interests. Member and manager information kept private (closed registry). Single-member LLCs permitted. No annual accounts required to be filed publicly. Frequently used as asset-holding vehicles within Cook Islands trust and asset-protection structures. The Cook Islands LLC offers enhanced charging-order protection: creditors cannot obtain a charging order against membership interests. Equivalent to a US LLC. |
| Foundation | — | Established under the Foundations Act 2012 and registered with the FSC; a separate legal entity distinct from both companies and trusts. Has no shareholders or members; governed by a council (minimum one member). May designate a supervisor/enforcer to oversee council operations. Can hold assets, enter contracts, and have beneficiaries. Foundation instrument (containing name, objectives, registered agent) filed with the FSC Registrar; governing rules remain private, held only by the registered agent. Used for asset protection, estate planning, philanthropy, and succession planning. Two-year statute of limitations on challenging asset transfers into the foundation. Closest US equivalent: Statutory business trust or nonprofit corporation. |
| International Trust | — | Settled under the International Trusts Act 1984 and registered with the FSC; among the most creditor-resistant trust structures globally due to the Cook Islands’ strong anti-forced-heirship and spendthrift provisions, short limitation periods for fraudulent conveyance claims, and the requirement that Cook Islands courts apply Cook Islands law. Settlor may retain certain powers (reserved powers trust). Administered by a licensed trustee company. Not a corporate entity but a separate fund; used extensively for asset protection, succession planning, and family wealth management. Closest US equivalent: Domestic Asset Protection Trust (DAPT). |
| International Partnership | — | Registered with the FSC under the International Partnerships Act 1984; must be certified by a licensed trustee company prior to registration.

Equivalent to a US Sole Proprietorship. |

Must appoint a local registered agent and maintain a registered office in the Cook Islands. Files an overseas company registration with the Cook Islands Registry Services (Ministry of Justice). Closest US equivalent: Foreign Corporation Branch/Representative Office. |

Collection notes
- Legal Registration: Issued by the Cook Islands Registry Services (Ministry of Justice) for domestic companies under the Companies Act 2017, or by the Financial Supervisory Commission (FSC) for international entities under the International Companies Act 1981-82 or Limited Liability Companies Act 2008. Issued electronically; contains entity name, registration number, date of incorporation, and Registrar’s authorisation. For FSC-registered entities, a Company Search Report (including entity name, registration number, registered office, administering trustee company, and company status) is available as a certified registry extract; this is the primary evidence of registration for IBCs and LLCs since the register is not publicly searchable.
- Constitutive Documents: For domestic companies under the Companies Act 2017, the constitutive document is a constitution (model or customised) filed with the Registrar at incorporation; the Act provides three default/model constitutions; companies may adopt a customised constitution and must provide a copy to the Registrar. For international companies under the International Companies Act 1981-82, the constitutive document is a Memorandum and Articles of Association filed with the FSC. For LLCs under the Limited Liability Companies Act 2008, the governing document is an LLC Agreement / Operating Agreement. Amendments must be notified to the respective Registrar.
- Tax Registration: The Revenue Management Division (RMD) of MFEM assigns a five-digit RMD Number upon tax registration. Entities incorporated under the Companies Act 2017 must apply separately for this number after company registration. International entities registered with the FSC are also required to register with the RMD for tax purposes under the Income Tax Act 1997. Cook Islands levies corporate income tax at 20% on profits for all companies. There is no formal printed TIN certificate as such; the RMD Number appears on tax returns, VAT registration confirmations, and official MFEM/RMD correspondence. VAT registration (if applicable) under the Value Added Tax Act 1997 issues a separate VAT registration number.
- Sector-Specific License: The Financial Supervisory Commission (FSC) is the sole licensing authority for all financial institutions in Cook Islands: banks (Banking Act 2011), general and offshore insurers (Insurance Act 2008), captive insurers (Captive Insurance Act 2013), money-changing and remittance businesses (Money-Changing and Remittance Businesses Act 2009; combined or separate licences), and trustee companies (Trustee Companies Act 2014). The FSC also registers and supervises international companies, LLCs, international trusts, international partnerships, and foundations. The Financial Transactions Reporting Act 2017 (FTRA 2017) governs AML/CFT obligations for all regulated entities. Cook Islands is not on the FATF grey/black list as of June 2026.
- Governance Records: Required to be maintained by all companies under the Companies Act 2017 and the International Companies Act 1981-82. For domestic companies, directors may appear in the online registry (registry.justice.gov.ck). For FSC-registered international companies and LLCs, the register of directors is private and held by the registered agent/trustee company — director identities do not appear on the public record. A Company Search Report from the FSC registry or a Certificate of Incumbency (listing directors and officers) from the trustee company serves as the evidential document.
- Signing Authority: Board resolution of the directors authorizing a named signatory is the standard mechanism; no statutory form prescribed — company letterhead resolution is standard practice for Cook Islands companies. For LLCs, a manager resolution or member consent serves the equivalent function. Power of attorney (notarized where required by counterparty) may also be used. Both instruments accepted by financial institutions and counterparties for Cook Islands entities.
- Address: For registered-office and operating-address verification. Lease agreement (no time limit) OR utility bill OR bank statement dated within 90 days accepted. Cook Islands does not mandate a specific form; the same documents used globally are accepted by FSC-regulated trustee companies and the Ministry of Justice registry.
- Good Standing: Issued by the respective Registrar (Cook Islands Registry Services / Ministry of Justice for domestic companies; FSC Registrar for international entities). Confirms the company is registered and in good standing — current on annual return filing and fee obligations. For FSC-registered international companies, the Certificate of Good Standing is a standard document required by financial institutions globally for account opening; must typically be no more than 6 months old. For domestic companies, available from registry.justice.gov.ck. Annual return filing fee is NZD 200 if filed late); maintaining good standing requires annual renewal fees. A Certificate of Incumbency issued by the registered agent/trustee company is commonly provided alongside or in lieu of a Certificate of Good Standing for FSC-registered entities.
Person roles
When you submit a person on the application body, set theirrole to one of Conduit’s canonical BusinessPersonRole values. Use this table to map a local corporate-governance title onto the right canonical role.
| Local role | Canonical API role | Description |
|---|---|---|
| Director | CONTROLLING_PERSON | Appointed officer with day-to-day executive authority over the company; named in the Register of Directors. For FSC-registered entities, director identity is private and held by the registered agent. A minimum of one director required for all company types. |
| Council Member (Foundation) | CONTROLLING_PERSON | Manages a Cook Islands Foundation under the Foundations Act 2012; equivalent function to a corporate director. Minimum one council member required; corporate council members permitted. Responsible for administering the foundation in accordance with its instrument and rules. |
| Registered Agent / Trustee Company | LEGAL_REPRESENTATIVE | FSC-licensed trustee company appointed as the Cook Islands registered agent for international entities; mandatory for all IBCs, LLCs, foundations, and international partnerships registered with the FSC. Holds and maintains all private records (register of members, register of directors) and issues certificates of incumbency. Acts as the primary AML/CFT compliance interface. |
| Authorized Signatory | LEGAL_REPRESENTATIVE | Person authorised via board resolution or power of attorney to sign on behalf of the company; the legal representative for specific transactions. No statutory form prescribed. |
Notes
- The Cook Islands has a dual-registry structure: domestic companies are registered with the Cook Islands Registry Services (Ministry of Justice) at registry.justice.gov.ck; international entities (International Companies, LLCs, Foundations, International Trusts, International Partnerships) are registered with the FSC at fsc.gov.ck. Conduit will primarily encounter FSC-registered international entities.
- For FSC-registered entities (IBCs, LLCs, Foundations), neither the register of members nor the register of directors is publicly accessible. All ownership and governance records are held privately by the licensed registered agent (trustee company). A Certificate of Incumbency and a Company Search Report from the FSC are the primary KYB anchors for these entities.
- Cook Islands levies corporate income tax at 20% on profits for all companies (domestic and international). Tax-resident International Companies (effective management in the Cook Islands, or 3+ Cook Islands-resident directors) are taxed on worldwide income at 20%. Non-resident International Companies are taxed at 20% only on Cook Islands-sourced income. International companies incorporated before 18 December 2019 had a transitional exemption; the first taxable income year for those grandfathered companies was 2022. There is no capital gains tax. A 15% withholding tax applies to dividends, interest, and royalties paid to non-residents (5% for residents). The Cook Islands is not a zero-tax offshore jurisdiction for new incorporations.
- The FSC launched a new secure international business registry in September 2024 (developed with ADB/PSDI support) providing enhanced AML/CFT functionality; the prior registry system was replaced. Registry information for international entities is now maintained in this new system.
- The Cook Islands International Trust (under the International Trusts Act 1984) is among the most creditor-resistant trust structures globally. Where a Cook Islands trust is part of the ownership chain, the trustee company is the registered entity owner for company purposes.
- Annual return filing is mandatory for all registered entities (NZD 200 if filed late). Failure to file results in loss of good standing and eventual striking off. Certificate of Good Standing and Certificate of Incumbency are the primary documents financial institutions require for account opening; these must typically be no more than 6 months old.
