Turning Losses Into a Tax Silver Lining
Every investor has positions that have not gone to plan. Some holdings sit at a loss, below the price you paid. Most investors look at these with frustration, waiting for recovery. But there is a systematic way to use these unrealised losses to reduce your tax bill right now: tax-loss harvesting. It is a concept that is equally applicable in India, and because India lacks a formal wash-sale rule, it is actually easier to execute here than in many other markets.
What Is Tax-Loss Harvesting?
Tax-loss harvesting means deliberately selling an investment that has declined in value to realise a capital loss. That realised loss can then be used to offset capital gains elsewhere in your portfolio, reducing your net taxable gains and therefore your tax liability. The investment need not be abandoned. After realising the loss, you can reinvest in the same or a similar asset to maintain your portfolio exposure. You have turned a paper loss into a tax-useful realised loss.
India’s Capital Gains Set-Off Rules
Short-Term Capital Loss (STCL) can be set off against both Short-Term Capital Gains (STCG) and Long-Term Capital Gains (LTCG) from any capital asset.
Long-Term Capital Loss (LTCL) can only be set off against Long-Term Capital Gains. It cannot be set off against Short-Term Capital Gains.
This asymmetry matters when you choose which losses to harvest. Short-term losses give you the most flexibility, they can offset both STCG (taxed at 20%) and LTCG (taxed at 12.5%). Harvest short-term losses first when you have both types available.
Carrying Forward Losses: Up to 8 Years
If your capital losses in a financial year exceed your capital gains, the unabsorbed loss can be carried forward for up to 8 assessment years. In each subsequent year, the carried-forward loss can be set off against eligible gains following the same STCL/LTCL rules. To carry forward a loss, you must file your income tax return on time, before the July 31 due date. Missing the deadline forfeits the right to carry forward the loss.
Filing your ITR on time is essential to preserve the right to carry forward capital losses, do not miss the deadline if you have losses to carry forward.
No Formal Wash-Sale Rule in India
In the United States, a wash-sale rule disallows the loss deduction if you buy a substantially identical security within 30 days of the sale. India has no such rule. You can sell a position to realise a loss and repurchase the same stock or fund immediately, same day if you choose. The loss is still fully deductible. Your economic exposure stays intact, but you have generated a tax-useful realised loss.
Be mindful of transaction costs: brokerage, STT, and the bid-ask spread add up. The cost of the sell-and-rebuy should be compared against the tax saving. For larger loss amounts, the tax saving almost always outweighs the transaction cost.
Timing: Before March 31
Tax-loss harvesting must be executed before the financial year ends on March 31. Losses realised after March 31 fall in the next financial year. Ideally, review your portfolio in February, it gives you time to assess your full-year gains picture and execute without rushing. Waiting until the last week of March is operational risk.
How to Execute Without Disrupting Your Allocation
The practical challenge is that selling a position changes your portfolio allocation. Here are the approaches:
If you want to maintain exact exposure: sell the position and immediately rebuy the same stock or fund. India’s no-wash-sale-rule advantage makes this clean. Your allocation stays intact; you have reset cost of acquisition to the current lower price.
If you want to improve your portfolio: use the opportunity to sell underperforming holdings and replace them with better alternatives in the same sector. Harvest the loss and upgrade simultaneously.
If you wait before reinvesting: you are out of the market during the wait. If the asset rallies, you miss it. This is the risk of sitting on cash between harvesting and reinvesting.
A Simple Example
You sold shares in December and made an STCG of Rs 80,000. In January, you notice shares of another company are at a short-term loss of Rs 50,000. If you sell before March 31 to realise the loss, you can set it off against the Rs 80,000 STCG. Your net taxable STCG becomes Rs 30,000 instead of Rs 80,000, saving Rs 10,000 in tax at the 20% STCG rate. If you immediately rebuy the same stock, your portfolio position is essentially unchanged.
