Arbitrage Fund Taxation — Why It's Taxed as Equity Despite Behaving Like Debt

An arbitrage fund's return profile looks and feels like a debt instrument — low volatility, modest and steady returns, minimal directional market risk. Its tax treatment, however, is unambiguously equity. Understanding why is the key to correctly comparing an arbitrage fund against the fixed-income alternatives it's most often pitted against.

What an Arbitrage Fund Actually Does

An arbitrage fund runs a market-neutral strategy — simultaneously buying a security in the cash (spot) market and selling the equivalent position in the futures market, capturing the price differential between the two rather than taking a directional view on where the underlying security is headed. Because the cash and futures legs offset each other, the strategy is deliberately hedged, and the fund's returns depend on the spread available in the market rather than on equity markets rising or falling.

The Tax Classification Test Looks at Structure, Not Risk Profile

The Income-tax Act's test for "equity-oriented fund" status doesn't ask how risky or volatile a strategy is — it asks what proportion of the fund's assets sit in equity and equity-derivative instruments. An arbitrage fund typically maintains at least 65% exposure to equity and equity derivatives (the cash-market leg of its trades, along with any un-hedged residual equity allocation), and this equity/equity-derivative exposure — not the fund's actual risk profile — is what determines its tax treatment. The fact that the futures leg largely offsets the cash-market position economically is irrelevant to this specific classification test; what matters is gross exposure to equity and equity derivatives, not net market risk.

Why This Produces a Genuinely Favourable Outcome

Because arbitrage funds clear the 65% equity/equity-derivative threshold, they receive the same preferential tax treatment as a diversified equity fund, despite carrying a meaningfully lower risk profile than most equity funds and a return profile that more closely resembles a short-duration debt instrument:

• Short-term (held 12 months or less): taxed at 20% under Section 111A, effective for transfers on or after 23 July 2024.
• Long-term (held more than 12 months): taxed at 12.5% under Section 112A, on gains exceeding the ₹1.25 lakh annual exemption (shared across all equity holdings, not a separate allowance for arbitrage funds alone).

This is a materially better outcome than the treatment a comparable-risk debt fund or fixed deposit would face — a debt fund unit acquired after 1 April 2023 is taxed entirely at slab rate under Section 50AA, and FD interest is taxed at slab rate as ordinary income, with no long-term concession available in either case.

Comparing Post-Tax Outcomes Against Fixed Deposits and Debt Funds

For an investor in a high tax bracket, the gap this creates is significant. Two instruments delivering broadly similar pre-tax annualised returns can produce very different after-tax outcomes: an arbitrage fund held beyond 12 months benefits from the 12.5% LTCG rate and the exemption threshold, while an equivalent fixed deposit's interest is taxed in full at the investor's slab rate (potentially 30% plus surcharge and cess), and a post-2023 debt fund holding faces the same slab-rate outcome with no offsetting exemption. This tax gap is the primary reason arbitrage funds are frequently recommended as a parking option for surplus funds, treasury-style short-term deployment, or a staging area before phased equity investment — the underlying strategy's low volatility combined with equity-style taxation is a genuinely useful combination for conservative, tax-aware investors.

IDCW From Arbitrage Funds Follows the Same Rules as Any Other Fund

Where an arbitrage fund distributes IDCW rather than the investor choosing Growth, the payout is taxed identically to IDCW from any other scheme — added to the investor's income and taxed at slab rate, with TDS deducted under Section 194K above the prescribed annual threshold for resident investors. Our companion article on IDCW taxation covers why the Growth option is usually preferable in more depth, and that comparison applies to arbitrage funds just as it does elsewhere.

Common Mistakes Worth Avoiding

A handful of errors recur often enough with arbitrage funds to be worth flagging explicitly: assuming the fund is taxed like a debt instrument simply because it behaves like one; redeeming just before the 12-month mark and paying 20% STCG rather than waiting a short additional period to qualify for the considerably more favourable LTCG treatment; treating the ₹1.25 lakh exemption as available separately for arbitrage fund gains on top of other equity gains, rather than understanding it as one shared annual limit; and claiming the Section 87A rebate against arbitrage fund STCG or LTCG, when special-rate income under Sections 111A and 112A is specifically excluded from that rebate regardless of the investor's overall income level.

Reporting Requirements

Both short-term and long-term gains from arbitrage funds must be reported in the Capital Gains schedule of the ITR under the appropriate section (111A for STCG, 112A for LTCG), with the scheme name, purchase and redemption dates, and gain computation detailed accurately — inconsistencies between what's reported and the AIS/capital gains statement from the fund's registrar are a common trigger for scrutiny notices.

Using Arbitrage Fund Taxation to Your Advantage

The favourable tax treatment on arbitrage funds is a genuine, structural benefit available to any investor holding beyond 12 months — but only if the holding period, exemption aggregation, and reporting are all handled correctly. We help investors plan arbitrage fund redemptions to capture this benefit fully and reconcile the resulting gains correctly at filing time.
