Why the Cayman Islands for Fund Formation
The Cayman Islands is the world's leading offshore domicile for investment funds, with over 11,000 registered funds managing approximately USD 4 trillion in assets. In my practice advising fund managers on offshore structures, I consistently see the Cayman Islands chosen for its combination of regulatory sophistication, tax neutrality, political stability, and well-developed fund services infrastructure.
The jurisdiction's appeal stems from several key advantages: zero corporate tax, no capital gains tax, no withholding tax on distributions, a modern and flexible regulatory framework under the Cayman Islands Monetary Authority (CIMA), and a large ecosystem of experienced fund administrators, auditors, and legal counsel. For US-based managers raising capital from institutional investors, a Cayman fund structure is often the default choice.
Typical Use Cases
Cayman funds are particularly common for hedge funds, private equity funds, venture capital funds, and master-feeder structures. US managers typically establish a Cayman master fund or Cayman feeder to accommodate non-US and tax-exempt investors, while maintaining a parallel Delaware LP for US taxable investors.
Fund Vehicle Types
The Cayman Islands offers several legal structures for investment funds. The choice of structure depends on your fund strategy, investor base, and operational requirements. I advise clients that structure selection is a critical decision that impacts taxation, governance, and investor flexibility.
Exempted Company
Exempted Company (Most Common)
A Cayman Islands exempted company is a corporation formed under the Companies Act that is exempt from certain local requirements. This is the most common structure for Cayman funds.
- Structure: Corporate entity with shares representing fund interests
- Liability: Limited liability for shareholders
- Governance: Board of directors required, can be managed by general partner structure
- Flexibility: Can issue multiple share classes with different terms
- Best For: Hedge funds, private equity funds, single manager funds
Segregated Portfolio Company (SPC)
Segregated Portfolio Company (SPC)
An SPC is a single legal entity that can create multiple segregated portfolios, each with separate assets and liabilities. This is the Cayman equivalent of a series LLC.
- Structure: Umbrella company with segregated portfolios for different strategies or managers
- Liability: Statutory segregation of assets and liabilities between portfolios
- Governance: Single board overseeing all portfolios
- Flexibility: Efficient for multi-strategy funds or fund of funds
- Best For: Multi-manager platforms, incubator funds, master-feeder structures
Limited Liability Company (LLC)
Limited Liability Company (LLC)
The Cayman LLC combines features of a company and a partnership, offering contractual flexibility similar to Delaware LLCs.
- Structure: Hybrid entity with members holding LLC interests
- Liability: Limited liability for members
- Governance: Flexible governance via LLC agreement, can be member-managed or manager-managed
- Flexibility: Highly flexible economic arrangements
- Best For: Private equity funds, co-investment vehicles, structures requiring partnership tax treatment
Unit Trust
Unit Trust
A unit trust is an unincorporated trust structure where the trustee holds legal title to assets for the benefit of unitholders.
- Structure: Trust with unitholders holding beneficial interests
- Liability: Generally limited liability for unitholders
- Governance: Managed by trustee, typically a licensed trust company
- Flexibility: Favorable for certain tax treaty structures
- Best For: Islamic finance structures, REIT-like funds, tax treaty planning
Structure Comparison
| Feature | Exempted Company | SPC | LLC | Unit Trust |
|---|---|---|---|---|
| Formation Time | 1-3 days | 1-3 days | 1-3 days | 1-2 weeks |
| Setup Cost | USD 5,000-10,000 | USD 10,000-15,000 | USD 5,000-10,000 | USD 8,000-12,000 |
| Annual Fees | USD 5,000-8,000 | USD 8,000-15,000+ | USD 5,000-8,000 | USD 6,000-10,000 |
| Flexibility | High | Very High | Very High | Moderate |
| US Tax Treatment | Corporation (check-the-box available) | Corporation per portfolio | Partnership (default) | Trust or Partnership |
| Multi-Strategy | Via share classes | Ideal - segregated portfolios | Via classes | Via sub-trusts |
CIMA Registration Requirements
The Cayman Islands Monetary Authority (CIMA) regulates investment funds under the Mutual Funds Act (2023 Revision) and the Private Funds Act (2023 Revision). Understanding which regulatory category applies to your fund is the first critical compliance decision.
Regulatory Categories
Cayman funds fall into one of four main categories:
| Category | Definition | Registration Requirement |
|---|---|---|
| Mutual Fund (Regulated) | Open-ended fund with 15+ investors or offers shares to public | Full registration with CIMA, ongoing regulatory oversight |
| Private Fund (Registered) | Closed-ended fund or open-ended with fewer than 15 investors and no public offering | Registration with CIMA, lighter regulatory requirements |
| Section 4(4) Exemption | Fund with exclusively professional/high-net-worth investors (specific criteria) | Apply for exemption from registration |
| Master Fund | Fund with only other funds as investors | Typically exempt if all feeder funds are regulated |
15-Investor Threshold
The 15-investor threshold counts beneficial owners, not nominee entities. For master-feeder structures, the master fund typically does not count individual feeder investors. This is a complex area requiring legal analysis, particularly for fund of funds structures. Miscounting can result in operating an unregistered mutual fund, which is a criminal offense.
Registered vs. Licensed Mutual Funds
If your fund qualifies as a mutual fund, you must determine whether it will be registered or licensed. The distinction primarily depends on initial investment minimums and investor sophistication.
Registered Mutual Fund
Most Cayman hedge funds are structured as registered mutual funds. Requirements include:
- Minimum Investment: At least USD 100,000 per investor (or waiver application)
- Offering Document: Must contain prescribed risk warnings and disclosures
- Auditor: Approved auditor required, annual audited financial statements
- Administrator: Administrator required if assets exceed USD 100 million or 100+ investors
- Annual Filing: Annual returns and financial statements to CIMA
- Fees: Registration fee USD 4,269 - USD 6,098 depending on investor count, annual fee similar
- Timeline: Registration typically completed within 2-4 weeks if complete
Licensed Mutual Fund
Licensed funds are subject to enhanced regulatory requirements and ongoing supervision:
- Minimum Investment: Less than USD 100,000 per investor (retail investors)
- Prospectus: CIMA-approved offering memorandum required
- Auditor: Approved auditor required
- Administrator: Licensed administrator required
- Custodian: Independent custodian required in most cases
- Directors: At least two directors, majority Cayman resident or approved jurisdiction
- CIMA Approval: Material changes require prior CIMA approval
- Fees: Higher fees than registered funds, plus application fee of USD 6,098
- Timeline: 6-12 weeks for licensing approval
Standard Practice for Hedge Funds
Institutional hedge funds typically structure as registered mutual funds with USD 1 million or higher minimums. This avoids the enhanced regulatory burden of a licensed fund while maintaining credibility with institutional investors. Private equity funds often use the private fund registration route.
Director and Service Provider Requirements
Cayman funds must appoint several service providers to satisfy regulatory requirements and operational needs. The quality and reputation of your service providers directly impacts investor confidence and regulatory standing.
Board of Directors
Exempted companies and SPCs require a board of directors. Key considerations:
- Composition: At least one director required, institutional funds typically have 2-3 directors
- Independence: Best practice is to have at least one independent director, required for licensed funds
- Residency: No Cayman residency requirement for registered funds
- Director Fees: USD 15,000 - USD 35,000+ per director annually
- Responsibilities: Fiduciary duties to fund, oversight of operations, approval of material decisions
Independent Directors
While not legally required for registered funds, independent directors provide governance oversight and help manage conflicts of interest. Major institutional investors often require independent directors. Director independence means no material relationship with the investment manager, administrator, or other service providers.
Fund Administrator
A fund administrator handles fund accounting, NAV calculations, investor services, and regulatory reporting. Requirements:
- Licensing: Must be licensed by CIMA if Cayman-based, or approved jurisdiction if offshore
- When Required: Mandatory for licensed funds, required for registered funds over USD 100M AUM or 100+ investors
- Functions: NAV calculation, investor subscriptions/redemptions, capital calls, financial reporting
- Costs: USD 30,000 - USD 100,000+ annually depending on fund size and complexity
Auditor
All regulated Cayman funds require an approved auditor:
- Approval: Must be approved by CIMA (Big 4 and major regional firms are pre-approved)
- Requirements: Annual audit of financial statements, submission to CIMA within 6 months of fiscal year-end
- Costs: USD 15,000 - USD 50,000+ for annual audit depending on fund size
Legal Counsel
Cayman legal counsel is essential for fund formation and ongoing compliance:
- Formation: Incorporation, offering document drafting, CIMA registration
- Ongoing: Material amendments, regulatory filings, investor documentation
- Costs: USD 25,000 - USD 75,000 for formation, USD 10,000 - USD 30,000 annually for ongoing work
Prime Broker / Custodian
For hedge funds, the prime broker provides custody, financing, and execution services:
- Selection: Major institutional prime brokers (Goldman Sachs, Morgan Stanley, JP Morgan, etc.)
- Requirements: Licensed funds generally require independent custodian separate from investment manager
- Documentation: Prime brokerage agreement, custody agreement, securities lending agreement
Substance Requirements
Following global tax transparency initiatives, the Cayman Islands introduced economic substance requirements under the International Tax Co-operation (Economic Substance) Act. These rules require Cayman entities conducting certain "relevant activities" to demonstrate adequate economic substance in the Cayman Islands.
Application to Investment Funds
Investment funds conducting "fund management business" as a relevant activity must satisfy substance requirements. However, most investment funds benefit from specific exemptions:
Investment Fund Exemption
Entities that are investment funds regulated by CIMA (registered or licensed mutual funds, registered private funds) are generally exempt from economic substance requirements. This exemption applies to most institutional funds. However, the fund must file an annual notification confirming its exempt status.
When Substance Requirements Apply
If your fund structure includes entities that are not regulated funds (holding companies, general partners, master funds with only institutional investors that avoid registration), substance requirements may apply:
- Directed and Managed: Entity must be directed and managed in the Cayman Islands
- Core Income-Generating Activities (CIGA): Must be undertaken in Cayman Islands
- Adequate: Expenditure, physical presence, and personnel proportionate to activity level
Substance Requirements for Fund Vehicles
For entities required to demonstrate substance:
- Board Meetings: Majority of board meetings held in Cayman Islands
- Directors: Sufficient directors with appropriate expertise present in Cayman
- CIGA: Taking investment decisions, managing risks related to assets held
- Physical Presence: Premises in Cayman appropriate for CIGA
- Employees: Adequate employees in Cayman with necessary qualifications
- Expenditure: Adequate operating expenditure in Cayman
Annual Reporting
All Cayman entities must file an annual Economic Substance Notification, indicating whether they conduct relevant activities and, if so, whether they satisfy substance requirements. Non-compliance can result in penalties of up to USD 120,000 and potential strike-off.
Tax Resident Alternative
Entities that are tax resident in another jurisdiction can satisfy substance requirements by demonstrating tax residency elsewhere. This is common for entities in master-feeder structures where the manager is based in the US or UK.
Tax Considerations and Neutrality
One of the primary advantages of Cayman fund structures is tax neutrality. The Cayman Islands imposes no direct taxes on funds or their investors, creating a tax-transparent structure that allows investors to be taxed based on their own tax circumstances.
Cayman Tax Environment
- No Corporate Tax: Cayman funds pay zero corporate income tax
- No Capital Gains Tax: No tax on investment gains or trading profits
- No Withholding Tax: No withholding on distributions to investors
- No Inheritance/Estate Tax: No estate or inheritance taxes
- Tax Undertaking: Funds can obtain 50-year tax exemption certificate from Cayman government
US Tax Considerations
For US-based managers and US investors, Cayman fund structures have important US tax implications:
PFIC Rules
Cayman funds are typically Passive Foreign Investment Companies (PFICs) under US tax law. US taxable investors face punitive PFIC taxation unless the fund makes a Qualified Electing Fund (QEF) election, which requires annual information reporting to investors. For this reason, most US managers establish separate onshore feeder funds for US taxable investors.
UBTI Considerations
US tax-exempt investors (pension funds, endowments, IRAs) are subject to Unrelated Business Taxable Income (UBTI) on certain types of income. Cayman funds that use leverage or conduct an active trade or business can generate UBTI for US tax-exempt investors, triggering US filing requirements and tax liability. Master-feeder structures help "block" UBTI.
Check-the-Box Election
Cayman exempted companies can elect to be treated as partnerships for US tax purposes by filing Form 8832 (check-the-box election). This avoids corporate-level taxation and provides flow-through treatment for US investors. However, this creates complex tax reporting requirements.
Master-Feeder Structures
The most common structure for US managers is a master-feeder arrangement:
- Cayman Master Fund: Holds all investments, offshore corporation (or check-the-box partnership)
- Delaware Feeder LP: For US taxable investors, invests into master fund
- Cayman Feeder Fund: For non-US and US tax-exempt investors, invests into master fund
- Blocker Corporation: Sometimes used for tax-exempt investors to block UBTI
US Tax Advice Essential
Cayman fund structures have significant US tax implications. US managers must engage experienced US tax counsel to structure appropriately for different investor classes. Failure to address PFIC, UBTI, and withholding issues can result in investor tax problems and damage to fund reputation.
FATCA and CRS Compliance
Cayman funds must comply with international tax information exchange regimes, specifically the Foreign Account Tax Compliance Act (FATCA) and the Common Reporting Standard (CRS).
FATCA
FATCA requires foreign financial institutions to report US account holders to the IRS. The Cayman Islands has an intergovernmental agreement (IGA) with the US:
- Registration: Cayman funds must register with the IRS and obtain a Global Intermediary Identification Number (GIIN)
- Classification: Most funds are Investment Entities under FATCA
- Due Diligence: Must identify US investors and reportable accounts
- Reporting: Annual reporting of US investor information to Cayman Tax Information Authority (TIA)
- W-8BEN-E: Funds provide W-8BEN-E forms to withholding agents establishing FATCA status
Common Reporting Standard (CRS)
CRS is the global equivalent of FATCA for automatic exchange of tax information. The Cayman Islands is a CRS participating jurisdiction:
- Scope: Similar to FATCA but covers investors from 100+ jurisdictions
- Due Diligence: Identify tax residency of all investors
- Self-Certification: Obtain tax residency self-certifications from investors
- Reporting: Annual reporting to TIA, which exchanges information with investor home jurisdictions
- Timeline: Reporting deadline is July 31 each year for prior calendar year
Compliance Process
In practice, FATCA/CRS compliance is typically handled by the fund administrator:
- Subscription Documentation: Includes FATCA/CRS self-certification forms
- Account Classification: Administrator classifies each investor account
- Annual Reporting: Administrator prepares and files reports with TIA
- Costs: Included in administrator fees, typically no separate charge
FATCA/CRS Non-Compliance
Failure to comply with FATCA can result in 30% withholding on US-source payments to the fund. CRS non-compliance can result in penalties from CIMA and the TIA. Both regimes require meticulous investor onboarding and data collection. I advise clients to work closely with administrators to ensure forms are complete before accepting subscriptions.
Costs and Timeline for Formation
Establishing a Cayman fund involves various one-time and ongoing costs. Based on my experience, here are realistic estimates for a typical institutional hedge fund or private equity fund:
Formation Timeline
Planning and Structuring (2-4 weeks)
Determine fund structure, regulatory category, investor base. Engage Cayman and US counsel, select service providers. Develop term sheet and preliminary offering memorandum.
Incorporation (1 week)
File incorporation documents with Cayman Registrar. Obtain certificate of incorporation. Establish bank account. Incorporation can be completed in 1-3 business days.
Documentation (3-6 weeks)
Draft and finalize offering memorandum, subscription documents, investment management agreement, administration agreement, and other fund documents. Parallel process with regulatory preparation.
CIMA Registration (2-4 weeks)
Prepare and submit CIMA registration application with required documents. CIMA processes registered fund applications within 2-4 weeks if complete. Licensed funds take 6-12 weeks.
FATCA/CRS Registration (1-2 weeks)
Register for GIIN with IRS. Register with Cayman TIA for CRS. Concurrent with CIMA process.
Launch Readiness (1-2 weeks)
Finalize all service provider agreements, establish operational procedures, test administration systems. Open prime brokerage account. Begin investor marketing.
Total Timeline: 8-12 weeks from start to launch for a registered fund. Licensed funds require 12-16 weeks.

Startup funds with minimal AUM should budget toward the lower end. Established funds with USD 500M+ AUM should budget toward the higher end or above.
Ongoing Compliance Obligations
Once your Cayman fund is established and registered, maintaining compliance requires ongoing attention to regulatory filings, investor reporting, and governance.
Annual Regulatory Filings

Late Filing Penalties
CIMA imposes automatic penalties for late filing of audited financial statements and annual returns. Penalties start at USD 732 and increase monthly, reaching USD 4,878 after 6 months. Persistent non-compliance can result in revocation of registration and striking off. I advise clients to calendar all filing deadlines and work with administrators to ensure timely compliance.
Cayman vs. Delaware Comparison
For US-based managers, the choice between a pure Delaware structure and a Cayman structure (or master-feeder) is a fundamental decision. Here is a practical comparison:
| Factor | Cayman Islands | Delaware |
|---|---|---|
| Tax Treatment | Tax neutral - no entity-level tax | Pass-through (LP) - partners taxed on K-1 |
| Formation Time | 8-12 weeks (with CIMA registration) | 1-4 weeks |
| Formation Cost | USD 75,000 - 150,000 | USD 15,000 - 40,000 |
| Annual Costs | USD 100,000 - 300,000+ | USD 15,000 - 50,000 |
| Regulatory Oversight | CIMA registration, annual filings, audited financials | Minimal (unless RIA/BD registered separately) |
| International Investors | Ideal - tax neutral structure | US tax withholding on certain income types |
| US Tax-Exempt Investors | Can block UBTI via master-feeder | Direct UBTI exposure if fund uses leverage |
| US Taxable Investors | PFIC issues - need separate feeder | Clean K-1 tax reporting |
| Investor Perception | Standard for institutional hedge funds | Standard for US-focused PE/VC |
| Administrator Required | Yes (for funds over certain size) | Not required (but common practice) |
| Audit Required | Yes - annual CIMA filing | Not required (but investors expect it) |
| Flexibility | High - flexible share classes | Very high - LP agreement fully customizable |
When to Choose Cayman
- Raising capital from non-US investors (particularly European and Asian institutions)
- US tax-exempt investors represent significant portion of investor base
- Hedge fund or liquid alternatives strategy (redemptions, leverage)
- Seeking institutional credibility and "gold standard" jurisdiction
- Plan to use leverage or derivatives that would create UBTI for tax-exempt investors
When Delaware May Be Sufficient
- Primarily US taxable investors (high-net-worth individuals, family offices)
- Private equity or venture capital fund (closed-end, capital calls)
- Smaller fund (under USD 50 million) with cost sensitivity
- No international investor marketing planned
- Simple investment strategy without leverage or UBTI concerns
Master-Feeder: Best of Both Worlds
Many institutional managers establish a master-feeder structure with both Cayman and Delaware feeders. This accommodates all investor types: non-US investors in Cayman feeder, US tax-exempt investors in Cayman feeder (or blocker), and US taxable investors in Delaware feeder. All feeders invest into a single Cayman master fund for unified portfolio management. While this increases costs, it maximizes fundraising flexibility.
