Indian AIF vs Offshore Fund (Cayman/Singapore/Mauritius) — Full Comparative Structuring Guide

For a fund manager raising India-focused capital, one of the earliest and most consequential decisions is domicile: register the fund as a SEBI-regulated Alternative Investment Fund onshore in India, or set up an offshore vehicle — typically in the Cayman Islands, Singapore, or Mauritius — that then invests into India through the FPI, FVCI, or FDI route. There is no universally right answer; the correct structure depends on the investor base being targeted, the strategy's liquidity profile, and how much regulatory and tax complexity the manager is prepared to carry. This guide sets out the comparison in full, distinct from the GIFT City / IFSC-specific structuring question, which sits somewhere between these two poles and is addressed separately.

The Core Trade-Off

An Indian AIF offers direct SEBI regulatory legitimacy, straightforward access to Indian institutional and domestic capital, and — for Category I and II schemes — pass-through tax treatment under the Income-tax Act, 1961, meaning income largely retains its character and flows through to investors without fund-level taxation. Its cost is a comparatively more prescriptive regulatory regime (investment conditions, concentration limits, reporting obligations, PPM and merchant-banker involvement) and, for global investors, unfamiliarity with Indian trust-law fund structures relative to the fund documentation conventions they are used to.

An offshore fund in Cayman, Singapore, or Mauritius offers structural familiarity to global institutional LPs (a Cayman exempted limited partnership, in particular, is the default global private funds vehicle that most international LPs' internal approval processes are built around), lighter-touch fund-level regulation, and — depending on jurisdiction and treaty position — potential tax efficiency on the India-sourced returns flowing up to the fund. Its cost is a second layer of regulatory and FEMA/foreign-investment-route compliance to actually deploy that offshore capital into India, ongoing treaty and anti-abuse scrutiny (addressed in more detail in our companion pieces on DTAA planning post-MLI and round-tripping red lines), and the practical reality that Indian domestic capital generally cannot invest into an offshore vehicle as easily as it can into a domestic AIF.

Indian AIF: Structural Profile

Regulatory Framework

Governed by the SEBI (Alternative Investment Funds) Regulations, 2012, an Indian AIF must register in Category I, II, or III, each with its own investment conditions, leverage rules, and permitted strategy scope. The fund is typically constituted as a trust (though company and LLP structures are also permitted under the Regulations, trusts remain overwhelmingly the market standard), with a SEBI-registered manager, an independent trustee, and a PPM filed through a SEBI-registered merchant banker.

Tax Treatment

Category I and Category II AIFs enjoy a specific pass-through status under Section 115UB of the Income-tax Act, 1961 — business income is taxed at the fund level, while all other income (capital gains, dividends, interest) retains its character and is taxed directly in the hands of investors as if they had earned it directly, with the fund required to withhold tax at applicable rates before distribution. Category III AIFs do not enjoy statutory pass-through status in the same manner and are generally taxed at the fund level (as an association of persons, at the maximum marginal rate, in most structures), which materially affects the after-tax return profile for Category III investors relative to Category I/II.

Investor Access

A domestic AIF is the natural, and often only practical, route for Indian resident investors (family offices, HNIs, domestic institutions, EPFO/insurance-regulated pools where permitted) to access the fund's strategy, since Indian residents face their own outbound investment restrictions under FEMA's Liberalised Remittance Scheme and overseas investment rules that make investing into an offshore Cayman or Singapore vehicle considerably more constrained. A manager targeting a blended domestic-and-foreign LP base will frequently find the Indian AIF route unavoidable for the domestic leg, regardless of what is chosen for the foreign leg.

Offshore Fund: Structural Profile

Cayman Islands

The Cayman exempted limited partnership remains the default global private funds vehicle, familiar to essentially every institutional LP's legal and compliance teams. Cayman imposes no direct taxation on the fund itself, offers strong structural flexibility (side letters, co-investment vehicles, parallel funds), and does not restrict the fund's investment strategy the way SEBI's category-specific conditions do. The trade-off: a Cayman fund investing into India must still route capital through an SEBI/RBI-recognised foreign investment channel (FPI for listed exposure, FVCI or FDI for unlisted), meaning the offshore wrapper does not eliminate Indian-side regulatory engagement — it adds a layer on top of it.

Singapore

A Singapore-domiciled fund — increasingly structured as a Variable Capital Company (VCC), Singapore's purpose-built collective investment vehicle introduced in 2020 — offers a well-regarded, MAS-regulated (or exempt, depending on structure and investor base) fund domicile with an extensive tax treaty network, geographic proximity to India, and a jurisdiction increasingly favoured by global LPs allocating to Asia generally, not India specifically. Singapore fund managers benefit from Singapore's own fund management incentive schemes in certain cases, and the jurisdiction's treaty position with India (discussed further below) has historically been an important structuring consideration.

Mauritius

Mauritius remains a long-established India-focused fund domicile, historically the single largest source of FDI and FPI inflows into India by treaty jurisdiction, owing to decades of favourable tax treaty treatment under the India-Mauritius DTAA. Mauritius Global Business Company structures remain in active use, though the jurisdiction's relative attractiveness has diminished since the 2016 protocol introduced source-based capital gains taxation for post-April 2017 investments (removing the historical capital-gains exemption for new investments, while preserving grandfathering for pre-2017 acquisitions), and the 2024 protocol's proposed Principal Purpose Test addition (discussed in our DTAA planning piece) adds a further anti-abuse layer that fund structurers must now factor in.

Tax and Treaty Comparison

The practical tax question for an offshore fund is no longer "does my jurisdiction offer a favourable capital gains exemption" — that era, for new investments, has substantially ended across Mauritius, Singapore, and Cyprus alike following the 2016-17 protocol amendments and the subsequent introduction of India's General Anti-Avoidance Rules (GAAR) and the MLI's Principal Purpose Test. What differs today between jurisdictions is largely: withholding tax rates on dividends and interest under the applicable treaty, the presence and rigour of Limitation of Benefits (LOB) provisions (Mauritius does not have an LOB clause and relies on PPT alone; Singapore's treaty benefits are conditioned on both PPT and a specific LOB test), and the jurisdiction's overall reputational and substance-maintenance profile with Indian tax authorities and with global LPs increasingly attentive to ESG and governance-quality considerations in fund domicile selection.

An Indian AIF, by contrast, sidesteps treaty analysis for its own domestic-facing structuring — there is no treaty question for an Indian trust investing in Indian securities — though foreign investors into that Indian AIF still separately need to consider their own treaty position with India (a distinct question addressed in our DTAA planning article), since the pass-through character of AIF income means the foreign investor's home-country and India treaty position governs their tax outcome much as if they had invested directly.

Fundraising and Investor Perception

Global institutional LPs — particularly US and European pension funds, sovereign wealth funds, and funds-of-funds — often have internal investment policy constraints that favour, or in some cases require, familiar offshore fund structures (Cayman ELP being the most universally accepted) over direct investment into an onshore emerging-market trust vehicle, irrespective of the underlying tax analysis. This is a genuine, non-tax driver of offshore structuring decisions: some LP capital is simply more accessible through a structure their own governance processes are built to approve quickly.

Conversely, an Indian AIF carries direct SEBI regulatory credibility that resonates strongly with India-focused domestic capital and with foreign investors who specifically value onshore regulatory oversight and transparency — a consideration that has grown in relevance as global LPs have become more attentive to regulatory substance following increased scrutiny of opaque offshore structures generally.

The Hybrid Reality

In practice, many India-focused managers of scale run parallel structures — an onshore Indian AIF to capture domestic capital and access India's own regulatory ecosystem directly, alongside an offshore feeder or parallel fund (Cayman, Singapore, or increasingly a GIFT City/IFSC vehicle) to capture global institutional capital that requires a familiar offshore wrapper — with both vehicles co-investing pro-rata into the same underlying portfolio companies under a coordinated investment management arrangement. This hybrid approach captures the advantages of both routes at the cost of running, and reconciling, two parallel sets of fund documentation, compliance calendars, and reporting obligations.

Decision Framework for Fund Managers

• Domestic capital is a meaningful part of the target LP base → an Indian AIF is close to unavoidable for that leg, regardless of what else is structured.
• Target LPs are predominantly US/European institutional investors with rigid internal fund-structure preferences → an offshore Cayman (or increasingly GIFT City) parallel vehicle materially widens the addressable investor base.
• Strategy is listed-market/liquid → the FPI route via an offshore fund, or a Category III AIF, both merit consideration, with the tax treatment difference (pass-through vs. fund-level taxation) being a first-order factor.
• Manager wants the simplest single structure and is comfortable with SEBI's regulatory regime → a standalone Indian AIF, without a parallel offshore vehicle, remains the lowest-complexity option, provided the target investor base does not specifically require an offshore wrapper.

Conclusion

The Indian AIF versus offshore fund decision is not primarily a tax-optimisation question anymore — GAAR, the MLI's Principal Purpose Test, and the narrowing of Mauritius/Singapore/Cyprus treaty benefits to grandfathered pre-2017 investments have flattened much of the historical tax advantage offshore structuring once offered. What remains is a genuine structural choice about investor access, regulatory posture, and operational complexity — and increasingly, the right answer for a manager with a genuinely global LP base is not "either/or" but a coordinated onshore-offshore structure built from the outset to serve both capital pools without creating unnecessary duplication or compliance drag.
