AIF vs SIF: Understanding the Differences and Investment Opportunities

Introduction

After PMS and mutual funds, SIFs (Specialised Investment Funds) have gained real traction — bridging a gap that existed between ₹500 SIPs and ₹50 lakh PMS minimums. 

But as the requirements of HNIs rise, so does the appetite for more sophisticated, less liquid, and potentially higher-returning strategies.

That's where Alternative Investment Funds come in.

But Which One Suits Your Profile? 

Keep reading to understand and compare both (structure, costs, risks, and taxation) so you can decide based on facts, not jargon.

What is an Alternative Investment Fund (AIF)?

An Alternative Investment Fund is a SEBI-regulated, privately pooled investment vehicle that collects capital from sophisticated investors and deploys it into non-traditional assets like;

• Private equity

• Venture capital

• Real estate

• Hedge strategies

• Structured credit 

In India, AIFs have a minimum investment of ₹1 crore and lock-in periods typically ranging from 3 to 10 years.

AIFs are classified into three SEBI categories:

• Category I: Invests in startups, SMEs, infrastructure, and social ventures. The government incentivises these because they fund economically beneficial sectors.

• Category II: Covers private equity, private debt, and real estate funds. No leverage allowed. The most common AIF category in India.

• Category III: Hedge fund-style strategies — long-short equity, derivatives, arbitrage. Can use leverage. 

(Bonus Fact: As of March 2026, India has 1,849 registered AIFs with cumulative commitments crossing ₹15.74 lakh crore.)

What Is a SIF and How Is It Different from an AIF?

A SIF is a SEBI-regulated pooled investment product launched under the mutual fund framework (effective April 2025) that offers advanced strategies like long-short equity and derivatives exposure at a ₹10 lakh minimum. 

SIF sits between traditional mutual funds and PMS/AIF in both cost and complexity.

In simple words;

Mutual fund = ₹100 entry, basic strategies, retail-friendly.

SIF = ₹10 lakh entry, advanced strategies (long-short, sector rotation), still pooled and regulated like an MF.

PMS = ₹50 lakh entry, direct stock ownership, fully customised.

AIF = ₹1 crore entry, private/alternative assets, illiquid, longest lock-in.

AIF vs SIF: Key Differences at a Glance

Read this table to understand the differences between AIF and SIF:

Hidden Costs: AIF vs SIF Fee Structures

When investing in AIF or SIF, the majorconcerns remains fees. SIF may sound cheaper as it operates under mutual fund expense ratio caps. But, on the same path, AIF involves more capital and fund manager’s involvement, hence fees may vary. 

The table below gives a clear distinction:

Risk Factors: AIF vs SIF

SIF has market risk because major investment includes equity and derivatives. Your capital fluctuates with listed markets, but you can exit. Comparatively, AIF risk includes illiquidity risk as your money is locked for years.

Taxation of AIFs and SIFs

Let us look at the taxation of AIFs and Specialized Investment Funds.

1. SIF

• STCG - Varies from scheme to scheme. While some are taxed at 20% STCG, a few SIFs may tax at individual slab rates. 

• LTCG - 12.5% above ₹1.25L (at redemption)

1. AIF

• Category I and II AIFs pass income through to you (slightly more complex filing). 

• STCG - 20% 

• LTCG - 12.5%

• Category III AIFs pay tax at the fund level at the maximum marginal rate before distributing returns. 

Conclusion: Which is better?

Neither is universally "better." They serve fundamentally different purposes in a portfolio.

You may choose SIF if your investable surplus is ₹10–50 lakh, want liquidity, access to advanced strategies (long-short, sector rotation) at mutual fund costs, or simply mutual-fund-like taxation. 

Likewise, AIF can suit those investors with a ₹1 crore+ corpus who want to diversify into private equity, venture capital, or other social ventures. 

Because “For most HNIs, building a portfolio, the answer isn't either/or. It's a mix of both, depending on their portfolio requirements.”
