Both are pooled vehicles — you hold units either way — but they sit under completely different SEBI regulations, with a 10x gap in entry ticket and very different tax treatment depending on the category. Here's a factual comparison, sourced to each framework's own current rules.
SIF (Specialised Investment Fund): operates inside an existing mutual fund AMC, under SEBI's SIF framework — essentially a mutual-fund-adjacent structure with wider strategy latitude (limited short positions, higher concentration limits) than an ordinary mutual fund scheme is permitted.
AIF (Alternative Investment Fund): a privately pooled investment vehicle regulated separately under the SEBI (Alternative Investment Funds) Regulations, 2012 — a distinct legal and regulatory framework from mutual funds entirely, historically used for venture capital, private equity, and hedge-fund-style strategies.
| Parameter | SIF | AIF (Category I / II / III) |
|---|---|---|
| Minimum Investment | ₹10 lakh per PAN, across all SIF strategies at one AMC — waived for accredited investors | ₹1 crore for most investors (a reduced ₹25 lakh threshold applies for employees/directors of the AIF's own manager, under long-standing AIF norms) |
| Regulatory Framework | SEBI SIF framework, operating under mutual fund regulations (Dec 2024 circular onward) | SEBI (Alternative Investment Funds) Regulations, 2012 — an entirely separate regulatory track from mutual funds |
| Categories | 7 SEBI-defined strategies across Equity, Debt, and Hybrid (e.g. Equity Long-Short, Sector Rotation Long-Short) | Category I (venture capital, infrastructure, SME, social-impact funds), Category II (private equity, debt funds, fund-of-funds — no significant leverage), Category III (hedge-fund-style, leverage and derivatives permitted) |
| Investor Cap | No investor cap disclosed under the SIF framework | Category III AIFs are capped at 1,000 investors per scheme |
| Ownership Structure | Pooled — units in the scheme | Also pooled — units in the fund, not the underlying securities |
| Liquidity Structure | Open-ended, close-ended, or interval, depending on the specific strategy | Category I/II funds are typically close-ended with multi-year lock-ins (common in PE/VC); Category III funds are more often open-ended |
| Taxation | Fund-level taxation, similar to mutual funds — LTCG/STCG rules by category (equity/debt/hybrid) | Category I and II AIFs generally get "pass-through" tax treatment (income taxed in investors' hands, not at the fund level); Category III AIFs are typically taxed at the fund level as an Association of Persons (AOP), a materially different — often less favourable — tax outcome |
| Distribution | Can be distributed by AMFI-registered Mutual Fund Distributors | Typically requires a direct relationship with the AIF or a separately licensed distributor — not distributed the way mutual funds/SIFs are |
Tax treatment is category- and structure-specific and can change with each Union Budget — confirm current rates with a tax advisor before investing in either vehicle.
The headline gap — ₹10 lakh vs ₹1 crore — gets most of the attention, but the tax treatment difference is often the more consequential one. A Category III AIF's fund-level AOP taxation can meaningfully change net returns compared to a SIF's mutual-fund-style pass-through taxation, even before comparing the underlying strategies. This is exactly the kind of detail worth confirming with a tax advisor against your own situation, not something to assume based on the strategy name alone.
This isn't a recommendation — it's a description of how each is generally used:
