Arbitrage Fund vs FD: The Tax-Efficient Alternative Smart Investors Use

Arbitrage Funds vs FDs: While Fixed Deposits offer guaranteed returns, they are taxed at your slab rate (up to 30%). Arbitrage Funds offer similar low-risk returns but are taxed as Equity (12.5% LTCG), making them far superior for post-tax income.

Tax rules mentioned are as per current Indian income tax laws applicable from FY 2024–25. Always consult latest regulations.

Fixed Deposits (FDs) are the "comfort food" of investing. They are safe, simple, and guaranteed. But for high-income earners, they come with a massive hidden cost: Taxation.

If you are in the 30% tax bracket, earning 7% on an FD means you actually only keep 4.9%. That barely beats inflation! Meet the smarter alternative: the Arbitrage Fund.

1. The Problem with FDs (It's Not Returns)

The problem isn't the interest rate; it's how the government treats that interest. FD interest is added to your total income and taxed at your slab rate.

You are essentially parking money, not growing it.

2. What is an Arbitrage Fund? (How it Works)

Arbitrage funds are Mutual Funds that profit from the price difference between the Cash Market and the Futures Market. It sounds complex, but it's actually a low-risk, market-neutral strategy based on price differences.

The "Pen" Analogy:

Because they are fully hedged, they have extremely low risk, comparable to Debt funds. But here is the magic: The government treats them as Equity Funds for tax purposes.

Note: Arbitrage funds are not capital-guaranteed like bank FDs, but their market risk is significantly lower due to fully hedged positions.

3. The Tax Battle: 30% vs 12.5%

This is where Arbitrage funds shine. Since they invest >65% in equity derivatives, the taxman treats them like stock investments.

Period Fixed Deposit (FD) Tax Arbitrage Fund Tax
Short Term (< 1 Year) Slab Rate (Up to 30%) 20% (STCG)
Long Term (> 1 Year) Slab Rate (Up to 30%) 12.5% (LTCG)

Frequently Asked Questions

Is Arbitrage Fund risk-free?

Arbitrage funds are low-risk but not risk-free. They do not take directional market bets (hedged), but they may carry limited credit and liquidity risk due to short-term debt instruments held for margin requirements.

Is Arbitrage Fund better than FD for 1 year?

Yes, especially if you are in the 30% tax bracket. Returns are taxed at 20% (STCG) for arbitrage funds vs 30% slab rate for FDs. For holdings > 1 year, the tax drops to 12.5% (LTCG).

Are returns guaranteed in Arbitrage Funds?

No. Unlike FDs, returns are market-linked. However, due to the nature of arbitrage (spot-futures spread), they typically deliver stable returns comparable to Liquid Funds (6.5% - 7.5%).
