4.3.2 Tax-Loss Harvesting
Tax-loss harvesting means selling an investment at a loss to offset gains elsewhere and reduce overall tax liability, then reinvesting in a similar, but not identical, asset to maintain the intended market exposure.
The basic mechanism
If one holding shows a loss and another shows a gain, realising the loss can offset the taxable gain, reducing the overall tax bill for that financial year. The investor then typically reinvests the proceeds into a similar asset, aiming to maintain roughly the same market exposure and risk profile while having captured the tax benefit from realising that specific loss.
Tax-loss harvesting is the practice of selling investments that are currently at a loss to realise a capital loss that can offset capital gains elsewhere in the portfolio. The loss reduces your taxable income from capital gains, lowering the tax bill. The sold investment is immediately or shortly replaced with a similar (but not identical) investment to maintain the portfolio's exposure and risk profile.
In the Indian context, short-term capital losses can be set off against both short-term and long-term capital gains from any asset class. Long-term capital losses can be set off only against long-term capital gains. Unabsorbed losses can be carried forward for up to 8 assessment years, but only if the return for the loss year is filed on time.
Why the replacement asset needs to be different enough
Reinvesting in an asset considered too similar or substantially identical to the one just sold can, in some tax regimes, result in the loss being disallowed for tax purposes under wash-sale style rules, if such rules apply. The replacement needs to be different enough to genuinely count as a new, distinct position under the applicable regulations, while still serving a broadly similar role in the overall portfolio.
The most common application in India is harvesting equity LTCG losses to offset equity LTCG gains, or selling losing equity positions near the end of the financial year to offset gains realised earlier. For example, if you realised ₹3 lakh in equity LTCG during the year (₹1.75 lakh taxable after the ₹1.25 lakh exemption), selling a fund currently showing ₹1.75 lakh in unrealised losses would offset the gain entirely, eliminating the tax liability.
The wash-sale concern is less formal in India than in the US (where the IRS has a specific 30-day wash-sale rule). India does not have an explicit wash-sale rule, but the principle of substance over form applies: if a transaction is purely tax-motivated with no change in investment exposure, it could potentially be challenged. The practical approach is to replace the sold fund with a similar but not identical fund (for example, switching from one Nifty 50 index fund to another AMC's Nifty 50 index fund) to maintain exposure while creating a genuine new cost basis.
Why the timing and rules genuinely matter
Specific rules around loss offsetting, carry-forward provisions for unused losses, and any wash-sale style restrictions vary and can change over time, so the details should always be checked against current, applicable tax regulation before executing this specific strategy near the end of any financial year.
How PriLytics helps. PriLytics shows realised and unrealised gains across every holding by financial year, making it far easier to identify genuine tax-loss harvesting opportunities before a deadline passes. See capital gains and tax.
Tax-loss harvesting should be driven by the tax calendar, not by market views. The goal is not to time the market but to realise paper losses that already exist and convert them into a tax benefit. It is most effective when done systematically near the end of the financial year (January-March), after assessing the year's cumulative capital gains and identifying positions with unrealised losses that can offset them. The harvesting reduces the current year's tax bill; the replacement investment continues compounding at a new, lower cost basis.
