Tax Loss Harvesting: Reduce Capital Gains Tax
Nobody likes losing money in the stock market. However, a red portfolio can actually be highly lucrative if you understand the mechanics of Tax Loss Harvesting—the legal strategy of using your losses to eliminate your tax bill.
Tax-loss harvesting involves selling loss-making investments before March 31st to offset realized capital gains and reduce your annual income tax liability.
- ✓ Offsetting Rules: Short-term capital losses can offset both STCG and LTCG; long-term losses can only offset LTCG under Section 70/71.
- ✓ 8-Year Carry Forward: Unadjusted capital losses can be carried forward for up to 8 consecutive assessment years if ITR is filed on time.
- ✓ Tax-Gain Harvesting: Harvest up to ₹1.25 Lakh in tax-free LTCG each year by selling and immediately repurchasing appreciated units.
1. How Tax Loss Harvesting Works
Throughout the financial year, you may have sold certain stocks or mutual funds at a massive profit. At the same time, you likely hold other stocks in your portfolio that have dropped significantly in value.
If you do nothing, you must pay Capital Gains tax on the profits. Tax Loss Harvesting involves deliberately selling the losing stocks to realize a "capital loss". The income tax department allows you to subtract these realized losses from your realized gains, lowering your net taxable profit.
A Simple Example
- Profit Booked: You sold HDFC Bank shares and made a Short-Term Capital Gain (STCG) of ₹1,00,000.
- Tax Liability: Normally, STCG is taxed at 20% (new budget rate). You owe ₹20,000 in tax.
- The Harvest: You have shares of another company currently sitting at a ₹1,00,000 loss. You sell those shares.
- New Tax Liability: Net Gain is now ₹0. Your tax bill is reduced from ₹20,000 to ₹0.

2. The Rules of Offsetting in India
The Income Tax Department has strict rules regarding which losses can offset which gains. You cannot mix them randomly.
| Type of Loss | Can be set off against STCG? | Can be set off against LTCG? |
|---|---|---|
| Short-Term Capital Loss (STCL) | Yes | Yes |
| Long-Term Capital Loss (LTCL) | No | Yes |
Crucial Takeaway: Short-term losses are highly versatile and can offset both short-term and long-term gains. Long-term losses can ONLY offset long-term gains. Ensure you run your exact scenario through our Capital Gains Tax Calculator to avoid classification mistakes.
3. Carrying Forward Unused Losses
What happens if your losses exceed your gains for the year? Or what if you had a terrible year in the market and booked a ₹5 Lakh loss, but had zero gains?
The Indian tax code allows you to carry forward Capital Losses for up to 8 consecutive Assessment Years. In the next 8 years, whenever you book a profit, you can use these old, accumulated losses to wipe out the new tax liability.
4. Re-entering the Position (Wash Sales)
A common question is: "What if I harvest the loss, but I still believe in the stock long-term?"
In the United States, there is a "Wash-Sale Rule" which prevents you from claiming a tax deduction if you buy the same stock back within 30 days. In India, there is currently no explicit Wash-Sale rule.
This means you can theoretically sell a stock on Monday to book a loss (harvesting the tax benefit) and buy the exact same stock back on Tuesday. This allows you to reset your purchase price while pocketing the tax savings. However, doing this excessively on an intraday basis may be classified as speculative business income rather than capital gains, so it is safer to buy it back after a few days.
5. Portfolio Rebalancing Synergy
Tax loss harvesting is not just a tax-saving trick; it is a vital component of portfolio health. Every year, certain asset classes will outperform others, skewing your risk profile. Harvesting losses gives you the perfect excuse to sell underperforming, high-risk assets and reallocate the remaining capital back into your target asset allocation model.

Conclusion
Capital gains tax can easily eat up 12.5% to 20% of your hard-earned stock market profits. By actively reviewing your portfolio in February and March each year and strategically harvesting losses, you can keep thousands—if not lakhs—of rupees from going to the tax department.
Tax-Gain Harvesting: The Annual ₹1.25 Lakh LTCG Free Reset
In addition to tax-loss harvesting, smart Indian investors practice annual Tax-Gain Harvesting before March 31st:
- The ₹1,25,000 Annual Exemption (Section 112A): Long-Term Capital Gains on listed equities and mutual funds up to ₹1.25 Lakhs per financial year are 100% tax-free. If you do not utilize this exemption, it lapses permanently for that financial year.
- The Step-Up Cost Basis Strategy: Sell long-term mutual fund units that have accumulated ₹1.25 Lakhs of profit, and immediately buy them back the next day. This resets your purchase cost basis higher without paying a single rupee in tax, permanently shielding those gains from future taxes!
