Tax Loss Harvesting in India: How I Save Tax on Mutual Funds Every March

Most investors think about taxes only at filing time. The smarter approach is to actively manage your tax liability throughout the year — using legal strategies that reduce what you owe without changing your investment exposure.

Two strategies are particularly relevant for Indian investors: LTCG harvesting (using the annual ₹1.25 lakh equity exemption) and tax loss harvesting (setting off losses to reduce taxable gains). Neither requires any exotic structure — just timing and awareness.

India's Capital Gains Framework (Quick Recap)

Equity and equity mutual funds:

• Short-term (< 12 months): STCG at 20%
• Long-term (≥ 12 months): LTCG at 12.5% on gains above ₹1.25 lakh per year

Debt mutual funds (purchased after April 1 2023):

• All gains taxed at slab rate regardless of holding period

Real estate:

• Short-term (< 24 months): Slab rate
• Long-term (≥ 24 months): 12.5% without indexation (post-July 2024)

Loss set-off rules:

• STCL (short-term capital loss): Can be set off against STCG or LTCG
• LTCL (long-term capital loss): Can only be set off against LTCG
• Unabsorbed capital losses carry forward for 8 years (ITR must be filed on time to carry forward)

Strategy 1: Annual LTCG Harvesting for Equity

The ₹1.25 lakh annual LTCG exemption on equity is per financial year and doesn't accumulate — if you don't use it in FY 2024-25, it's gone. It doesn't carry over to FY 2025-26.

The opportunity: Every year, you can realize up to ₹1.25 lakh of equity LTCG completely tax-free by selling units/shares and immediately buying them back. This resets your cost basis to the current (higher) price, reducing future taxable gains.

How it works in practice:

Say you invested ₹5 lakh in a Nifty 50 index fund in 2022. By 2025, it's worth ₹7.5 lakh — LTCG of ₹2.5 lakh.

Strategy: Sell ₹6.25 lakh worth of units (representing ₹1.25 lakh of LTCG — the rest is return of capital). LTCG = ₹1.25 lakh (tax-free). Immediately buy back the same fund with ₹6.25 lakh. Your new cost basis is ₹6.25 lakh (instead of the original lower cost). Future gains are calculated from this higher base.

Net effect: ₹1.25 lakh of gains locked in tax-free. Cost basis reset upward. When you eventually sell permanently, your taxable gain is reduced by exactly ₹1.25 lakh.

Annual compounding benefit: If you harvest ₹1.25 lakh of LTCG tax-free every year for 20 years, you eliminate ₹25 lakh of future taxable gains. At 12.5% LTCG tax, that's ₹3.125 lakh in tax saved — plus the compounding effect of those tax savings reinvested.

Is There a Wash Sale Rule in India?

In the US, the "wash sale rule" prevents you from buying back the same security within 30 days of selling at a loss for tax purposes. This rule does not exist in India. You can sell and immediately rebuy the same fund or stock — the gain or loss is recognized for tax purposes.

This makes LTCG harvesting and tax loss harvesting much more straightforward in India than in most developed markets. There's no waiting period, no substantially identical security issue.

Practical note: You still pay brokerage, STT (Securities Transaction Tax), and other transaction charges on the sell and rebuy. For equity funds, STT is 0.001% on equity MF redemptions. Factor in these costs — for small amounts, transaction costs may exceed the tax benefit.

Strategy 2: Tax Loss Harvesting

If you have investments showing unrealized losses (market value below cost), you can sell them to realize the loss and use it to offset taxable gains elsewhere.

Example: You have ₹3 lakh in realized LTCG from selling equity shares. You also hold a midcap fund that's down ₹1.5 lakh from your purchase price (held > 12 months — LTCL). If you sell the midcap fund:

• Realized LTCL: ₹1.5 lakh
• Set off against LTCG: ₹3L − ₹1.5L = ₹1.5L net LTCG
• Tax: 12.5% × (₹1.5L − ₹1.25L exemption) = 12.5% × ₹25,000 = ₹3,125 (instead of 12.5% × ₹1.75L = ₹21,875 without harvesting)
• Tax saved: ₹18,750

You can immediately rebuy the midcap fund — no wash sale rule. Your holding period for the new units starts fresh (but the investment thesis is unchanged).

STCL is more flexible: Short-term capital loss can offset both STCG and LTCG. If you have a loss within 12 months, it's more useful than a long-term loss (which can only offset LTCG).

Harvesting Across the Portfolio

Within equity MFs: Sell loss-making funds and rebuy the same fund (no restriction). Or rebuy a similar fund from a different AMC to maintain exposure while recognizing the loss.

Debt MF losses: Debt MF losses (post-April 2023) are taxed at slab rate. A debt MF loss can be set off against debt MF gains or other capital gains to reduce taxable income.

Between equity and debt: STCL from debt can offset LTCG from equity. LTCL from equity can offset LTCG from debt.

Timing Considerations

Do LTCG harvesting before March 31: LTCG from equity gains above ₹1.25L in a year is taxable. Time your harvest to stay within the annual ₹1.25L limit — don't trigger more gains than needed.

Carry-forward requires timely ITR filing: If you have unabsorbed capital losses this year that you want to carry forward to next year, you must file your ITR by the due date (July 31 for individuals not subject to audit). A belated return (filed after July 31) does not allow carry-forward of current-year capital losses.

STT and transaction costs: Each sell-and-rebuy pair incurs transaction charges. For equity mutual funds, redemption has no exit load after 1 year (typically) and minimal STT. For individual stocks, full brokerage and STT apply both ways. Do the math — tax saved must exceed transaction costs.

The LTCG Exemption Reset Strategy: A 20-Year Example

Ravi invested ₹10 lakh in a Nifty 50 index fund in FY 2024-25. He harvests ₹1.25 lakh LTCG each year by selling and rebuying.

Over 20 years:

• Total LTCG harvested tax-free: ₹1.25L × 20 = ₹25 lakh
• Tax saved at 12.5%: ₹3.125 lakh
• By resetting cost basis annually, his final sale triggers far less LTCG than if he had never harvested

Without annual harvesting, his cost basis remains ₹10 lakh throughout. If the fund grows to ₹1.2 crore after 20 years, his LTCG is ₹1.1 crore, and tax (above ₹1.25L exemption) = ~₹13.5 lakh.

With annual harvesting, his cost basis is reset progressively higher each year. The difference in final tax bill can be ₹3–5 lakh depending on returns.

What Not to Do

Don't harvest losses simply to defer tax indefinitely: Losses carried forward still expire after 8 years. If you can't find gains to offset against within 8 years, the loss is wasted.

Don't ignore transaction costs for small portfolios: For a ₹5 lakh portfolio, the annual LTCG from index fund growth might be ₹60,000 — entirely within the ₹1.25L exemption without any action. Harvesting only matters when unrealized gains exceed the exemption.

Don't confuse LTCG harvesting with STCG: Selling units held < 12 months generates STCG at 20%, not covered by the ₹1.25L exemption. Ensure the position has been held at least 12 months before harvesting for LTCG treatment.

Tax-efficient investing is not just about choosing low-expense instruments — it's about managing when you realize gains and losses. These strategies require no market timing, no exotic products, just calendar awareness and a few transactions per year.
