Cayman Islands Fund Domicile
Cayman Islands Fund Domicile
Cayman is the default offshore fund domicile — a zero-tax, common-law jurisdiction whose exempted company and exempted limited partnership serve global hedge funds, private-equity partnerships and SPAC shells. It is chosen for tax neutrality plus allocator familiarity, and it anchors the tax-neutral master in a master-feeder-structures stack. It is the pick when the investor base spans non-US and US-tax-exempt capital and no EU passport is needed. ^[reports/Fund domicile profiles/Cayman Islands.md]

| Regulator | Cayman Islands Monetary Authority (CIMA) |
| Tax headline | No income, corporate, capital-gains or withholding tax; 20-year tax-concession undertaking |
| Market rank/share | Number one offshore domicile; 56% of emerging hedge-fund flagships (AIMA/Marex 2026) |
| Signature vehicles | Exempted company, Exempted Limited Partnership (ELP), Segregated Portfolio Company (SPC) |
| Killer app | 21-day private-fund registration plus the tax-neutral master in a feeder stack |

Legal forms
- Exempted company — open-ended hedge funds, closed-end corporate funds, SPVs, blockers and holdcos
- Exempted Limited Partnership (ELP) — closed-end private equity and private credit, the Delaware LP analogue for carry and commitments
- Segregated Portfolio Company (SPC) — umbrella and multi-strategy platforms, master-feeder, ring-fenced cells
- Unit trust — mutual and open-ended funds, Japan-facing structures
- Foundation company (2017) — private-client, SPV and wealth-planning vehicles with no shareholders
The SPC is the segregated vehicle in Cayman funds. The protected-cell-company label belongs to BVI and to Cayman insurance practice; Cayman funds use the SPC. ^[reports/Fund domicile profiles/Cayman Islands.md]
Tax posture
- Fund level is zero — no corporate income, capital-gains, profits or withholding tax, and no exchange controls
- A tax-concession undertaking under the Tax Concessions Act locks neutrality for 20 years on exempted companies, extendable
- No treaty network — neutrality trades away treaty access on portfolio-asset withholding
- US taxable investors should not hold a Cayman fund directly: the open-ended corporate is a PFIC and the closed-end corporate is a CFC, so US taxable money rides a Delaware partnership feeder instead
- US tax-exempt and non-US investors enter via the corporate feeder or blocker, avoiding effectively-connected income, US filing and UBTI
- Carried interest sits at the ELP general-partner layer under home-country rules (for US GPs, the §1061 three-year rule)

Why chosen, when not
- Choose for tax neutrality, no withholding, deep allocator familiarity (led every AIMA/Marex survey since 2017), Privy Council courts and the 21-day window
- Avoid when the investor base is US taxable (use Delaware), when an EU or EEA passport is needed (use Luxembourg or Ireland), or when treaty relief on portfolio withholding is needed
Structure roles
- Default master fund in global stacks; offshore feeder or blocker alongside a Delaware onshore feeder, both feeding a Cayman master LP
- Also serves as SPV or holdco and, via the SPC, the umbrella or cell layer
- Does not serve the onshore pass-through role that Delaware holds — the two appear together rather than competing

Regulatory weather 2023–2026
- Enacted: Private Funds Act 2020 (in effect February 7, 2020) brought closed-end funds under CIMA supervision with 21-day registration and annual audit
- Enacted: Beneficial Ownership Transparency Act 2023 (in force July 31, 2024, enforced January 2025) extended registers to limited partnerships
- A legitimate-interest beneficial-ownership register launched February 2025 (not fully public)
- Exited the FATF grey list October 2023 and the EU AML list February 2024
- Not enacted: no Pillar Two or QDMTT; economic-substance rules exclude investment funds
- CRS and FATCA enforcement is now active
^[reports/Fund domicile profiles/Cayman Islands.md]
Watch items
- Escalating compliance burden: monthly beneficial-ownership deposit, economic-substance filings, enforced CRS penalties
- A live UK push toward a public beneficial-ownership register, resisted on privacy grounds
- Gulf and US manager-migration pull, but record 2025 registrations show no measurable de-Caymanization to date
