Tax-Loss Harvesting in India: A Strategic Guide for Equity Investors
Tax-loss harvesting is a portfolio management strategy where investors intentionally sell underperforming investments at a loss to offset capital gains realized from profitable investments. By reducing the net taxable capital gains, investors can lower their tax liability without fundamentally changing their investment thesis. The sold investment can often be repurchased after a brief interval (observing wash-sale considerations), allowing the investor to maintain their desired portfolio allocation while capturing a tangible tax benefit.
How Capital Gains Are Taxed on Equity in India (FY 2025-26)
Under the Finance Act 2024, equity capital gains in India are taxed at two rates. Long-Term Capital Gains (LTCG) on listed equity shares and equity-oriented mutual funds held for more than 12 months are taxed at 12.5% on gains exceeding Rs 1.25 lakh per financial year. This exemption threshold was raised from Rs 1 lakh and the rate increased from 10% effective 23 July 2024. Short-Term Capital Gains (STCG) on equities held for 12 months or less are taxed at a flat 20% (increased from 15%). Additionally, a 4% Health and Education Cess applies on the tax amount.
These rates make tax planning meaningful for active investors. On Rs 3 lakh of LTCG (above the exemption), the tax is Rs 21,875 (12.5% of Rs 1.75 lakh). On Rs 1 lakh of STCG, the tax is Rs 20,000. Strategic loss harvesting can reduce or eliminate these amounts.
Set-Off Rules: The Foundation of Loss Harvesting
The Income Tax Act prescribes specific rules for setting off capital losses against capital gains. Understanding these rules is essential for effective tax-loss harvesting:
- Short-Term Capital Loss (STCL): Can be set off against both Short-Term Capital Gains (STCG) and Long-Term Capital Gains (LTCG). STCL is more flexible and should be considered first when deciding what to harvest.
- Long-Term Capital Loss (LTCL): Can only be set off against Long-Term Capital Gains (LTCG). LTCL cannot be used to offset STCG, making it less versatile than STCL.
- Carry-Forward: If losses exceed gains in the current year, the unabsorbed loss can be carried forward for up to 8 assessment years. However, this carry-forward benefit is only available if you file your income tax return by the due date under Section 139(1). Missing the deadline forfeits the carry-forward right entirely.
When to Harvest Losses: Timing and Strategy
The optimal time for tax-loss harvesting is typically toward the end of the financial year (January to March) when you have a clearer picture of your total capital gains for the year. However, opportunities can arise at any time during market downturns. The key strategic considerations include: reviewing your portfolio for positions showing unrealized losses; calculating the potential tax saving against the transaction costs (brokerage, Securities Transaction Tax, and other charges); ensuring the loss is a genuine realized loss (the security must be actually sold through a recognized stock exchange); and deciding whether to repurchase the same security after a reasonable gap or switch to a similar but not identical investment.
Practical Example of Tax-Loss Harvesting
Consider an investor who has realized Rs 5 lakh in equity LTCG and Rs 2 lakh in equity STCG during FY 2025-26. Without harvesting, their tax liability is: LTCG tax = 12.5% of (5,00,000 minus 1,25,000) = Rs 46,875; STCG tax = 20% of 2,00,000 = Rs 40,000. Total tax = Rs 86,875. Now suppose the investor identifies stocks with Rs 2 lakh in unrealized short-term losses. By selling these stocks, they book Rs 2 lakh STCL. The STCL first offsets the Rs 2 lakh STCG (reducing it to zero, saving Rs 40,000 in STCG tax). The LTCG remains Rs 5 lakh, but the overall tax saving is Rs 40,000. If transaction costs are Rs 1,000, the net benefit is Rs 39,000.
The LTCG Exemption Harvesting Strategy
A related but distinct strategy is LTCG exemption harvesting. Since the first Rs 1.25 lakh of equity LTCG is exempt each year, investors can sell profitable long-term equity holdings to book up to Rs 1.25 lakh in gains tax-free, and immediately reinvest. This resets the cost basis higher, reducing future taxable gains. Over a multi-year period, this annual harvesting of the exemption can save a significant cumulative amount. For instance, harvesting Rs 1.25 lakh per year over 10 years means Rs 12.5 lakh in gains are realized tax-free, saving approximately Rs 1.56 lakh in taxes at the 12.5% rate.
Wash Sale Rules in India
Unlike the United States, India does not have explicit “wash sale” rules that disallow a loss if the same security is repurchased within a specified period. However, the tax authorities can invoke the General Anti-Avoidance Rules (GAAR) under Sections 95 to 102 of the Income Tax Act if a transaction is deemed to lack commercial substance and is primarily arranged for obtaining a tax benefit. In practice, if you sell a stock at a loss and immediately buy it back at the same price, the Assessing Officer could argue that the transaction was a sham. A reasonable approach is to wait at least a few trading days before repurchasing, or switch to a closely correlated but different security (e.g., selling one IT sector stock and buying another).
Transaction Costs to Consider
Tax-loss harvesting involves real transaction costs that reduce the net benefit. These include brokerage charges (typically 0.01% to 0.05% for discount brokers), Securities Transaction Tax (0.1% on sell side for delivery equity trades), Exchange Transaction Charges (0.00345%), SEBI Turnover Fees, GST on brokerage, and stamp duty. For a typical sell-and-rebuy transaction, total costs range from 0.2% to 0.5% of the transaction value. Our calculator accounts for these as a configurable percentage so you can see the true net benefit after costs.
