Cayman Islands Fund
A Cayman Islands fund is an investment vehicle incorporated in the Cayman Islands as an exempted limited partnership (for PE/VC funds) or exempted company/segregated portfolio company (for hedge funds), domiciled offshore to achieve tax neutrality for non-U.S. investors and tax-exempt U.S. investors, while remaining subject to Cayman regulatory oversight.
Key takeaways
- The Cayman Islands provides a tax-neutral environment: no income, capital gains, withholding, or corporate tax, ensuring offshore investors are taxed only in their home jurisdictions.
- The most common structure is the master-feeder fund: a Cayman master fund receives investments from both a domestic (Delaware LP) feeder for U.S. taxable investors and an offshore (Cayman) feeder for non-U.S. and U.S. tax-exempt investors.
- The Cayman Regulatory Authority (CIMA) regulates hedge funds under the Mutual Funds Law, requiring registration for funds with 15+ investors and annual financial statement filings.
- The Cayman exempted limited partnership (ELP) is the preferred vehicle for PE funds, structurally analogous to a Delaware LP with equivalent flexibility in profit-sharing and governance provisions.
- FATCA and CRS reporting obligations have significantly increased the compliance burden for Cayman funds, requiring disclosure of U.S. beneficial owners to the IRS and OECD member-country tax authorities respectively.
Explanation
The Cayman Islands is the world's dominant offshore financial center for hedge funds and a major jurisdiction for private equity. The appeal is fundamentally tax-driven: the Cayman government levies no income, capital gains, withholding, inheritance, or value-added tax on fund income, enabling offshore investors to receive fund returns gross of local Cayman taxation. Each investor then pays taxes in their home jurisdiction (if any) on their fund income — a pass-through that avoids the double taxation that would occur if a domestic fund were used by international investors.
The master-feeder architecture is the predominant structure for global hedge funds. The master fund (Cayman exempted company or limited partnership) holds all portfolio positions and executes trades through the prime broker. Two or more feeder funds invest into the master: a Delaware limited partnership feeder serves U.S. taxable investors who require a partnership structure for flow-through tax treatment; a Cayman exempted company feeder serves non-U.S. investors and U.S. tax-exempt investors (pension funds, endowments) who are indifferent to entity type but may have UBTI (unrelated business taxable income) concerns with leverage that a corporate structure avoids.
For private equity, the Cayman exempted limited partnership (ELP) has become the standard vehicle in many cross-border transactions, governed by the Exempted Limited Partnership Law. The ELP closely mirrors the Delaware LP in terms of governance flexibility (the LPA can customize virtually any aspect of the fund's operation, profit allocation, and key-person provisions), while offering Cayman's tax neutrality and the increasingly important benefit of being recognized by EU jurisdictions under the Alternative Investment Fund Managers Directive (AIFMD) as an equivalent structure.
The regulatory framework has evolved substantially. CIMA requires hedge fund registration under the Mutual Funds Law for funds with 15 or more investors, annual audited financial statements (within 6 months of fiscal year-end), and registration fee payments. The Cayman AML framework requires fund administrators and managers to conduct CDD (customer due diligence) and enhanced due diligence on high-risk investors. The Economic Substance Law (2019) requires certain Cayman entities engaged in relevant activities to demonstrate substance in the Cayman Islands — though investment funds are exempt from substance requirements if they register as 'investment funds.'
FATCA (Foreign Account Tax Compliance Act) and the OECD Common Reporting Standard (CRS) have transformed the opacity historically associated with offshore structures. Cayman funds must register as foreign financial institutions, identify U.S. persons among their investor base, and report account information to the Cayman Tax Information Authority, which forwards it to the IRS under an intergovernmental agreement. CRS extends similar automatic information exchange to 100+ participating countries, effectively ending offshore tax evasion as a benefit of Cayman structures.
Example
A New York-based hedge fund manager launches a global macro strategy. The fund structure includes: (1) A Cayman master fund (exempted company) holding all positions; (2) A Delaware LP feeder for U.S. taxable investors (structured as a limited partnership for Schedule K-1 tax reporting); (3) A Cayman exempted company feeder for European pension funds and Asian family offices. The $500M raised splits approximately $150M via the Delaware feeder and $350M via the Cayman feeder. The Cayman structure ensures that the German pension fund and Singapore family office receive portfolio returns with no Cayman withholding tax, paying only to their domestic tax authorities (zero and zero, respectively, in this case). The fund registers with CIMA, appoints a Cayman-licensed administrator, and files annual audited GAAP financials.
