A Cayman SPV is a special purpose vehicle formed under Cayman Islands law, most often as an exempted company, used to pool capital from investors who prefer or need a structure outside the United States. Fund managers use one most often as a feeder in a master feeder structure, where a Cayman entity collects capital from tax exempt and non-US investors and invests it alongside a domestic entity that holds capital from taxable US investors, keeping each group’s tax treatment separate inside its own vehicle.
The reason a Cayman feeder gets used at all comes down to United States tax rules that treat tax exempt organizations and non-US persons differently from taxable domestic investors, not to any special legal protection the Cayman Islands themselves provide over a Delaware entity.
This guide covers why fund managers reach for a Cayman feeder, how the master feeder structure separates investor types, and where the tradeoffs sit compared with a single Delaware SPV.

Why tax exempt and non-US investors need a different structure
A tax exempt organization, such as a pension fund, university endowment, or private foundation, generally does not pay federal income tax on its investment income. That exemption breaks down if the organization earns unrelated business taxable income, income from a trade or business regularly carried on that is not related to its exempt purpose, which can arise if the organization invests directly in a fund or SPV that uses leverage or operates an active business through a pass through entity. Non-US investors face a related but separate issue: if a fund or SPV is treated as engaged in a US trade or business, foreign investors can become subject to US tax filing obligations and withholding on their share of income that is effectively connected with that business, under rules the IRS describes as effectively connected income.
How a Cayman feeder blocks these problems
A Cayman exempted company can elect, under the check the box rules, to be taxed as a corporation for US tax purposes using Form 8832. Once that election is made, the Cayman entity itself absorbs any unrelated business taxable income or effectively connected income at the entity level, and the tax exempt or non-US investor above it receives a dividend from a foreign corporation instead of a direct share of the underlying business income, which avoids passing the problematic income through. This function is why a Cayman feeder used this way is commonly called a blocker.
Delaware SPV vs. Cayman feeder
| Delaware SPV | Cayman feeder | |
|---|---|---|
| Typical investor | Taxable US individuals and entities | Tax exempt organizations and non-US investors |
| US tax treatment | Pass through to the investor | Entity level, blocking pass through income |
| K-1 reporting for investors | Yes, typically Schedule K-1 | No, investors receive dividend treatment instead |
| Formation familiarity | Most US counsel and investors know the entity type well | Requires local registered office and counsel familiar with Cayman law |
How a master feeder structure fits together
In a typical master feeder structure, a Delaware feeder collects capital from taxable US investors and a Cayman feeder collects capital from tax exempt and non-US investors. Both feeders invest into a single master vehicle, often also organized outside the US, which holds the actual portfolio company position. Each feeder’s investors only ever deal with their own entity and its own tax reporting, while the master vehicle lets the manager run one consolidated investment process instead of managing two separate portfolios side by side.
Who actually needs this structure
A single deal SPV with a small number of taxable US investors generally does not need a Cayman feeder at all, and a straightforward Delaware LLC is usually the simpler starting point. The structure earns its added complexity once a raise includes enough tax exempt capital, a foreign sovereign wealth fund, or a meaningful block of non-US individual investors that blocking their exposure to pass through income becomes worth the extra entity, its own registered office, and separate tax filings. See US investment access for global entrepreneurs for the broader picture of how non-US participants fit into an SPV.
What a Cayman exempted company involves in practice
A Cayman exempted company needs a registered office in the Cayman Islands and is required to file an annual return with the Cayman Islands government. Beyond that, requirements can change and vary with the entity’s activity, so a manager should confirm current filing and substance requirements with Cayman counsel before relying on any specific figure. What does not change is the US side of the analysis: the entity’s US tax classification election, and the accredited investor or qualified purchaser standard used to admit investors into whichever Investment Company Act exclusion the overall structure relies on.
Investment Company Act limits still apply across the structure
Forming a Cayman feeder does not change how many investors the overall structure can have under the Investment Company Act. A structure relying on Section 3(c)(1) is still capped at 100 beneficial owners across both feeders combined, and a structure relying on Section 3(c)(7) still requires every investor in both the Delaware and Cayman feeders to be a qualified purchaser. The Cayman entity changes tax treatment, not the investor eligibility rules the fund relies on to avoid being regulated as an investment company.
A worked example of a master feeder split
For example, suppose a fund manager is raising $5 million for a deal, with $2 million coming from a university endowment and a family office based outside the US, and $3 million coming from taxable US individuals. The manager could form a Cayman feeder for the $2 million and a Delaware feeder for the $3 million, with both feeders investing into a single master LLC that holds the actual position. The endowment and the foreign family office receive dividend income from the Cayman entity rather than a Schedule K-1 showing their share of the underlying business activity, while the domestic investors receive the K-1 treatment they would expect from a standard SPV.
Frequently asked questions
Why set up an SPV in the Cayman Islands?
A Cayman SPV is generally used to block unrelated business taxable income for tax exempt investors and to keep non-US investors out of direct US tax filing obligations, by having the Cayman entity absorb that income at the entity level instead of passing it through.
What is the difference between a Cayman SPV and a Delaware LLC?
A Delaware LLC generally passes income through to its investors, who report it on a Schedule K-1. A Cayman entity that elects corporate tax treatment blocks that pass through, so tax exempt and non-US investors receive dividend treatment instead.
Does every SPV with foreign investors need a Cayman feeder?
No. A small number of non-US investors who are comfortable with US tax filing obligations can often invest directly into a Delaware SPV. A Cayman feeder becomes worth the added cost once a meaningful share of the capital comes from tax exempt organizations or non-US investors who need the blocked structure.
