Tax-loss harvesting is useful only when the realised loss can legally offset taxable gains and the repurchase does not create a worse investment outcome. India does not have a simple US-style wash-sale rule that automatically disallows every quick repurchase, but artificial or non-genuine transactions can still be challenged under general anti-abuse and market-integrity principles.

Rules in practice
| Rule |
|---|
| Tax-loss harvesting is a timing strategy, not a separate deduction: a realised eligible loss can offset only the categories permitted by set-off rules. |
| Short-term capital loss and long-term capital loss have different set-off boundaries. |
| Wash-sale style behaviour in India is not governed by a simple US 30-day rule; genuine transfer, beneficial ownership and anti-avoidance principles still matter. |
| Transaction costs, exit loads and loss carry-forward compliance can erase the apparent tax benefit. |
Short-term capital loss can generally be set off against both short-term and long-term capital gains, while long-term capital loss is ordinarily restricted to long-term capital gains.
A loss exists for tax only after an actual transfer; an unrealised fall in the portfolio does not create a set-off.
Carry-forward of unabsorbed capital loss depends on return-filing conditions and the statutory carry-forward period, so late filing can destroy future value.
STT, brokerage, bid-ask spread and the chance of a rebound while out of the position should be included in the harvesting decision.
Selling an investment solely for tax and immediately buying a highly correlated substitute can change tracking, risk and transaction costs even if the tax law permits the trades.
Off-market or circular arrangements lacking commercial substance are qualitatively different from genuine exchange trades at market price.
Harvesting should be evaluated after considering the tax rate on the gain being offset; a ₹1 lakh loss does not save ₹1 lakh of tax.
Harvest tax losses only after measuring the investment cost of the trade
The set-off rules create the tax opportunity: a short-term capital loss can generally be set off against short-term or long-term capital gains, while a long-term capital loss is restricted to long-term capital gains. An unrealised fall is not a tax loss; the asset has to be transferred. Unabsorbed capital loss can be carried forward for the statutory period only if the return-filing conditions are satisfied.
The investment decision should be made before the tax decision. Selling a high-conviction holding solely to save tax can create spread, brokerage, STT, tracking error and rebound risk. If the investor re-enters later at a higher price, the tax saving can be overwhelmed by the lost market move.
India does not have a simple US-style 30-day wash-sale rule that automatically disallows an exchange trade merely because the same security is repurchased quickly, but artificial, circular or non-commercial arrangements can still attract scrutiny under broader anti-abuse principles. Maintain normal market evidence and a genuine investment rationale.
| Situation | Practical treatment |
|---|---|
| STCL ₹80,000; LTCG ₹1,50,000 | STCL can generally be considered for set-off against the LTCG, subject to the full tax computation. |
| LTCL ₹80,000; STCG ₹1,50,000 | LTCL generally cannot be set off against STCG; it is restricted to LTCG. |
| Loss remains after current-year set-off | Carry-forward value depends on filing the return within the prescribed conditions and tracking the loss schedule. |
Worked example 1
An investor has ₹3 lakh of listed-equity short-term gains and an unrelated share position showing a ₹1.2 lakh unrealised short-term loss. If the loss position is genuinely sold, the ₹1.2 lakh realised STCL can generally be set off against eligible capital gains, reducing the net taxable gain. The investor then compares tax saved with STT, brokerage, spread and the risk of being out of the market before deciding whether and when to rebuild exposure.
Worked example 2
An investor has ₹3 lakh of taxable gains and a share position showing an unrealised ₹1.2 lakh loss. Selling the losing position would crystallise the loss, but the investor expects a near-term event and the stock has a wide spread. The right comparison is not “₹1.2 lakh loss = ₹1.2 lakh tax saving”. It is the tax reduction produced by the loss versus transaction cost, market risk while out of the position and whether the replacement asset changes the portfolio thesis.
Common mistakes to avoid
- Calling an unrealised mark-to-market fall a harvested tax loss.
- Using a long-term capital loss against short-term gains.
- Missing return-filing conditions needed to carry a loss forward.
- Entering circular/off-market trades designed only to manufacture a paper loss.
Action checklist
- Classify each gain/loss as short-term or long-term.
- Confirm the loss will be realised before year-end.
- Map legal set-off restrictions before trading.
- Estimate tax saved, not just loss amount.
- Include STT, fees and spread in the economics.
- Use genuine market transactions with commercial substance.
- File the return on time if loss carry-forward may be needed.
Records to retain
- Broker capital-gain statement and contract notes
- Lot-wise holding period/cost records
- Current-year gain/loss set-off working
- ITR loss schedule and carry-forward acknowledgement
Questions users actually ask
Can STCL be set off against LTCG?
Generally yes. Short-term capital loss has broader set-off than long-term capital loss.
Can LTCL be used against STCG?
Generally no. Long-term capital loss is set off against long-term capital gains.
Does a portfolio fall create a tax loss automatically?
No. The loss generally becomes relevant for capital-gain set-off only when a transfer crystallises it.
Is there a fixed 30-day wash-sale rule in India?
India does not use the same simple statutory 30-day wash-sale rule familiar from the US, but sham or non-commercial arrangements can still raise anti-abuse concerns.
