Structuring the capital: cross-border tax depth

This is the deepest part of the work and the part that quietly decides whether a cross-border deal succeeds. Once capital crosses a border, the structure has to manage how each investor is taxed — or the fund's own investors pay the price. Structuring is where a specialist earns their keep.

The master-feeder structure

When you have U.S. taxable investors alongside foreign or tax-exempt ones, you separate them into feeders that both invest into one master fund:

• U.S. feeder for U.S. taxable investors — a Delaware partnership with pass-through treatment.
• Offshore feeder (typically Cayman or BVI) for non-U.S. and U.S. tax-exempt investors — a corporate "blocker" form that stops U.S. filing obligations and UBTI.
• Master fund — usually itself an offshore entity electing to be treated as a partnership for U.S. tax — where the actual investing happens; both feeders invest through it.

Blockers: why a C-corp sits in the structure

A "blocker" is a corporation inserted into the structure to block the flow-through of income that would otherwise create a tax problem for a particular investor. The two classic problems blockers solve:

• For foreign investors: investing directly into a U.S. operating partnership can generate effectively connected income (ECI), which drags the foreign investor into U.S. tax filing and tax on a net basis. A blocker corporation absorbs that — the foreign investor owns shares in a corporation, not a partnership interest, so the ECI stops at the blocker.
• For U.S. tax-exempt investors: leverage or operating income flowing through a partnership can create unrelated business taxable income (UBTI), taxing an otherwise tax-exempt pension, endowment, or IRA. A blocker converts that flow-through into corporate dividends, which are generally not UBTI.

The onshore (U.S.) C-corp blocker

For inbound investment into U.S. assets — especially U.S. real estate and U.S. operating businesses — a domestic C-corporation blocker is often used. The foreign or tax-exempt investor owns the C-corp; the C-corp holds the U.S. investment. Key trade-offs a sponsor must weigh:

• The cost: the blocker pays U.S. corporate income tax (currently 21% federal) on its earnings. That is the price of "blocking" — you accept entity-level tax to spare the investor direct filing and worse rates.
• The benefit on exit: structured well, the foreign investor can sell the shares of the blocker rather than the underlying asset, which can convert what would be ECI/FIRPTA gain into a cleaner capital transaction. Blocker exit planning is its own discipline.
• Leverage: blockers are often capitalized partly with shareholder debt so interest deductions reduce the blocker's taxable income — subject to the earnings-stripping and interest-limitation rules.

Offshore blockers (the Cayman/BVI feeder) and onshore C-corp blockers do different jobs — the offshore feeder addresses fund-level flow-through for the foreign investor pool; an onshore C-corp blocker is frequently used at the asset level for U.S. ECI/FIRPTA exposure. Many cross-border structures use both.

Cayman vs. BVI: choosing the offshore domicile

When you need an offshore feeder or master, the two dominant choices are the Cayman Islands and the British Virgin Islands. Both are tax-neutral, English-common-law, creditor-respected jurisdictions — but they are not interchangeable. The right choice depends on investor expectations, fund type, and cost sensitivity. (Note: the offshore entity is always formed by qualified counsel in that jurisdiction; Randall architects the U.S. side and coordinates.)

The Cayman Islands

• The institutional default. Cayman is what most institutional allocators, prime brokers, and administrators expect, especially for hedge funds. If you are raising from sophisticated global LPs, Cayman carries the least explaining.
• Regulatory regime: open-ended funds generally register under the Mutual Funds Act and closed-ended funds under the Private Funds Act, with CIMA (the Cayman Islands Monetary Authority) oversight, audited financials, and ongoing filings.
• Trade-off: more regulatory infrastructure and cost than BVI — which for institutional money is a feature, not a bug.

The British Virgin Islands

• Leaner and lower-cost. BVI is often chosen for smaller or emerging-manager funds, startups, and SPV-style vehicles where Cayman's cost and regulatory weight are more than the deal needs.
• Regulatory regime: the BVI offers approved-manager and incubator/approved-fund regimes designed specifically for emerging managers — lighter-touch, faster, and cheaper to launch, with caps on investors or AUM.
• Trade-off: some of the largest institutional allocators still prefer Cayman; BVI may require slightly more investor education depending on the LP base.

The other tax tools underneath

• ECI / FDAP analysis — how a foreign investor's U.S. income is characterized: ECI (net-basis, return-filing) vs. FDAP (flat withholding on passive income).
• PFIC planning — managing passive foreign investment company exposure for U.S. taxable investors who end up in offshore vehicles (QEF and mark-to-market elections).
• FIRPTA — the regime taxing foreign investors on gains from U.S. real property; central to real estate funds (see Deploy).
• Treaty optimization — using income-tax treaties to reduce withholding for eligible investors.
• FATCA & CRS — the U.S. and global information-reporting regimes the offshore vehicles must comply with.
