Master-Feeder Funds: Structure, Tax Logic and Operations

A master-feeder structure is a set of funds in which two or more "feeder" funds collect capital from different groups of investors and invest substantially all of it into a single "master" fund, which holds the actual portfolio. The structure lets a manager run one investment strategy while giving each investor group a vehicle suited to its tax and regulatory needs.

Master-feeder structures are most common in hedge funds and other open-ended strategies, and are also used in private credit and some private equity programmes. They solve real tax problems, but they roughly multiply the accounting, audit and reporting work.

The basic structure#

 US taxable investors       Non-US and US tax-exempt investors
          |                              |
   Onshore feeder                 Offshore feeder
 (e.g. Delaware LP)          (e.g. Cayman exempted company)
          \                              /
           \                            /
                 Master fund
       (often Cayman, treated as a partnership
          for US federal income tax purposes)
                       |
                   Portfolio

• Onshore feeder: typically a Delaware limited partnership, treated as a partnership for US tax purposes. US taxable investors receive K-1s and are taxed on their share of income whether or not it is distributed.
• Offshore feeder: typically a Cayman Islands exempted company (or similar offshore vehicle), treated as a corporation for US tax purposes.
• Master fund: often a Cayman exempted limited partnership or a company that has elected to be treated as a partnership for US tax purposes, so income and losses flow through to the feeders.

The GP or investment manager usually controls all three entities, and the investment manager is appointed at the master level so that trading or investing happens in one place.

Why use a master-feeder structure#

Different investors, different tax problems#

• US taxable investors generally prefer a pass-through vehicle, so they avoid an extra layer of entity-level tax and retain the character of income, such as long-term capital gain.
• US tax-exempt investors (pensions, endowments, foundations) want to avoid unrelated business taxable income (UBTI), which can arise from leveraged investments or operating businesses held through partnerships. Investing through an offshore corporate feeder can act as a "blocker", because the investor receives corporate dividends rather than a share of the underlying debt-financed income.
• Non-US investors generally want to avoid filing US tax returns and being treated as engaged in a US trade or business. A non-US corporate feeder can provide that separation, though certain US-source income can still be subject to withholding at the feeder level.

One portfolio, one set of trades#

Without a master, a manager running parallel onshore and offshore funds would need to split every trade or investment between them, with the risk of different prices, allocation disputes and diverging performance. Pooling at the master means one portfolio, one set of positions and consistent results across feeders, apart from feeder-level fees and expenses.

Efficiency at scale#

Combining assets at the master can improve access to counterparties, financing and investment sizes that neither feeder could achieve alone.

Alternatives in private equity#

Closed-end private equity funds more often use parallel funds (separate funds that invest side by side in each deal on a pro rata basis) and alternative investment vehicles (AIVs) or blocker corporations formed deal by deal for investors with particular tax concerns. See private equity fund structures for how those compare.

Cayman regulatory considerations#

Cayman Islands vehicles are common for offshore feeders and masters. Open-ended funds are generally regulated by the Cayman Islands Monetary Authority (CIMA) under the Mutual Funds Act, and since the 2020 reforms a master fund of a regulated feeder is generally required to register with CIMA as well. Closed-ended funds are generally registered under the Private Funds Act. Registered funds face ongoing obligations such as annual audited financial statements filed with CIMA, annual returns and fees, and appropriate AML/KYC arrangements, including designated AML officers. Requirements change over time, so confirm current rules with Cayman counsel and administrators; our Cayman Islands guide covers the KYC/AML side.

How allocations work#

Each feeder owns a percentage of the master, and the master's results are allocated to the feeders according to their capital accounts. In an open-ended fund, that percentage changes every time a feeder takes in subscriptions or pays redemptions, so allocations must be recomputed every dealing period.

Worked example: allocating master income#

Assume at the start of a month the master's NAV is $500M:

The master earns net income of $10M in the month (after master-level expenses). Allocation by opening ownership:

Then, at month-end, the onshore feeder invests a further $16M into the master from new subscriptions and the offshore feeder redeems $6M. New ownership for next month: onshore $220M of $520M (about 42.3%), offshore $300M (about 57.7%). Each feeder then applies its own management fee, any performance allocation and its own expenses before computing investor-level NAV.

Most masters use opening-percentage allocation per period as shown. Some use more granular methods, such as allocating gains and losses by lot for tax purposes. Whatever method is used, it must match the documents and be applied consistently, because auditors will test it.

Operational requirements#

1. Separate books for every entity. The master and each feeder need their own general ledger, trial balance and financial statements. See fund accounting.
2. Investor accounting at the feeders. Capital accounts, subscriptions, redemptions or capital calls, and fee calculations live at the feeder level.
3. Consistent valuation. The master's NAV, calculated under its valuation policy, drives every feeder's results.
4. Intercompany reconciliation. Each feeder's investment in the master must equal its capital account on the master's books at every period end.
5. Audits. Each entity typically needs audited financial statements; the master's audit is usually completed first so the feeders can rely on it.
6. Tax reporting. The master issues K-1s to the feeders; the onshore feeder then issues K-1s to its investors. The offshore feeder generally provides investors with whatever information they need for their own tax regimes, such as PFIC-related statements for any US holders.
7. Regulatory filings. Form PF, Form ADV and offshore filings may each treat the structure differently; check how the master and feeders must be reported.

Calendars matter: feeder reporting depends on master numbers, so delays at the master cascade.

How Privatis helps#

Privatis runs the master and each feeder as separate entities on a double-entry ledger with period close, so investments in the master reconcile to the master's capital accounts. NAV and portfolio valuations, management fee calculation, investor reporting through the LP portal, K-1 delivery, a compliance filings calendar and a full audit trail support the extra layers a master-feeder structure creates.

Tax and regulatory treatment of master-feeder structures depends on specific facts, so confirm your approach with fund counsel and tax advisers.
