Since the Budget 2024 reset of capital gains tax — long-term capital gains on listed equity now taxed at 12.5 percent on amounts exceeding Rs 1.25 lakh per year, short-term at 20 percent — tax-loss harvesting has become more relevant for Indian investors than ever before. The math is straightforward: every rupee of LTCG above the Rs 1.25 lakh exemption costs you 12.5 paise in tax, and every rupee of harvested loss offsets that exposure rupee-for-rupee. Done deliberately across a 25-year investing life, harvesting can preserve lakhs of compounding capital. India's tax framework is, in some respects, more favourable to harvesters than the United States — there is no formal wash-sale rule. This guide walks through the strategy, the rules, and the execution tactics.
The Rs 1.25 Lakh LTCG Exemption — The Cornerstone
Budget 2024 set the long-term capital gains exemption on listed equity and equity-oriented mutual funds at Rs 1.25 lakh per financial year per taxpayer. Gains up to this threshold are completely tax-free; gains above are taxed at 12.5 percent. This exemption is per taxpayer, not per stock, fund, or transaction — you aggregate all LTCG across equity sales in the year, and only the net amount above Rs 1.25 lakh attracts tax.
The strategic implication is immediate: you should book at least Rs 1.25 lakh of long-term equity gains every year, even if you intend to stay invested. The mechanism is simple — sell the units that have appreciated the most, recognise the gain (covered by exemption), and immediately rebuy similar units. The cost basis of the rebought units is now the higher current price, which means future capital gains are calculated from this elevated base. This is sometimes called "tax-gain harvesting" or "cost-basis stepping up." For a household with Rs 50 lakh in equity mutual funds and 12 percent annual returns, that is around Rs 6 lakh of unrealised gains per year — most of which can be stepped up tax-free annually.
The Loss Harvesting Mechanism
The Income Tax Act allows capital losses to offset capital gains under specific rules. Short-term capital losses can be offset against both short-term and long-term capital gains in the same year. Long-term capital losses, however, can only be offset against long-term capital gains — not short-term. Unabsorbed losses (those that cannot be set off in the current year) can be carried forward for up to eight assessment years, provided you file your return on time. Carry-forward losses retain their character — short-term remains short-term, long-term remains long-term — when used in future years.
The strategic implication is that loss harvesting is most valuable when you have realised gains in the same year. If you sold a stock or fund at a profit and the gain crosses the Rs 1.25 lakh exemption, look across your portfolio for any holding currently below cost. Selling that loss-making holding offsets the gain. If the loss exceeds the gain, the unabsorbed portion carries forward. If you have no gains in the current year, harvesting still has value — the carried-forward loss reduces tax on future gains, including on the deliberate gain-bookings you do each year to step up your cost basis.
STCG vs LTCG — The Tax Arbitrage
Short-term capital gains on equity are taxed at 20 percent — significantly higher than the 12.5 percent on long-term. This rate gap creates a structural reason to hold equity for at least 12 months whenever possible. But it also creates an arbitrage opportunity in harvesting: short-term losses are more valuable than long-term losses because they can offset both STCG (taxed at 20 percent) and LTCG (taxed at 12.5 percent), while long-term losses can only offset LTCG.
The optimal harvesting hierarchy is: first, use short-term losses to offset short-term gains (saves 20 percent of the loss amount). Second, use any leftover short-term losses against long-term gains (saves 12.5 percent). Third, use long-term losses against long-term gains (saves 12.5 percent). Long-term losses cannot offset short-term gains, so do not waste a long-term loss against an STCG. Track the character of your losses carefully when filing.
India Has No Wash-Sale Rule — But Be Careful
The United States has a 30-day wash-sale rule that disallows tax losses if the same security is repurchased within 30 days. India has no equivalent statutory provision. You can sell a stock at a loss on Monday and buy it back on Tuesday with the loss fully claimed. This is a real edge for Indian investors compared to American counterparts.
However, two caveats apply. First, the income tax department has the general anti-avoidance power under Section 96 of the Income Tax Act (GAAR) to disregard transactions whose primary purpose is to avoid tax with no commercial substance. Selling and buying back the exact same stock on the same exchange on the same day, repeatedly, with no intervening price movement, could be challenged as a sham transaction. Second, even without GAAR, intra-day round-trip transactions may attract scrutiny because they leave a clean audit trail of "tax-driven" trading. The prudent practice is: separate the sell and buy by at least one trading day, and consider buying a similar but not identical asset (e.g., sell Nifty 50 ETF, buy Nifty Next 50 ETF) where appropriate. This delivers comparable economic exposure without resembling a same-stock round-trip.
The Annual Harvest Calendar
An efficient harvester runs the following calendar each year. In January, do a portfolio review: identify all positions that are currently below cost, separated into short-term (under 12 months held) and long-term (over 12 months). Compute realised gains booked so far in the year. In February, project the year-end position — incoming SIP gains, expected redemptions, ESOP exercises if any. Plan the harvest scale: how much loss to book and which positions to liquidate. Execute in late February or early March, leaving at least three to four weeks before year-end to allow for settlement and any unexpected market volatility. Avoid the last week of March — settlement cycles and broker congestion can derail planned trades.
Separately, every January or February, identify positions sitting on long-term gains above the Rs 1.25 lakh threshold and execute the gain-booking step-up. This is not the same as loss harvesting — it is paying zero tax (within the exemption) to reset cost basis. Done annually, this strategy keeps your unrealised LTCG below the threshold and avoids future tax bunching.
What Counts as "Equity" for the Rs 1.25 Lakh Exemption
The Rs 1.25 lakh exemption applies to long-term capital gains on listed equity shares and units of equity-oriented mutual funds (defined as funds with at least 65 percent equity allocation in the trailing year). Direct listed shares on Indian stock exchanges qualify. So do equity mutual funds, ELSS (after the three-year lock-in completes), index funds tracking equity indices, and equity ETFs. International equity mutual funds and gold ETFs do not qualify — they have a different tax treatment.
Debt mutual funds purchased after April 2023 are taxed at slab rates regardless of holding period — there is no LTCG concession or exemption. Real estate gains are taxed under separate provisions (Section 54, 54F, 54EC). Sovereign Gold Bonds held to maturity are exempt from capital gains entirely. Each asset class has its own tax mechanics, and harvesting across them requires understanding the specific rules. For mixed-asset portfolios, run the full picture through the capital gains tax calculator.
The Compounding Math of Harvesting
Consider a Rs 50 lakh equity portfolio earning 12 percent annually. Without any harvesting, after 20 years the portfolio grows to roughly Rs 4.82 crore, with realisation triggering LTCG tax of approximately 12.5 percent on the gain above Rs 1.25 lakh. After tax, the residual is around Rs 4.27 crore. With annual harvesting — booking the Rs 1.25 lakh tax-free gain each year and stepping up cost basis — the same portfolio after 20 years still realises Rs 4.82 crore but with substantially lower residual taxable LTCG, because much of the appreciation was already stepped up tax-free over the years. Net residual after the final realisation can be Rs 4.55 crore or more — Rs 28 lakh of additional terminal wealth from the harvesting alone.
Add loss harvesting in years where markets dip — booking Rs 5 to 10 lakh in losses in a bad year, offsetting it against future gains — and the cumulative tax saving compounds to even larger numbers. A disciplined harvester can capture an additional 0.5 to 1.0 percent of annual after-tax return without changing the underlying investment selection at all. Over 25 years, this is the difference between Rs 4.5 crore and Rs 5.5 crore at retirement on the same investment portfolio.
Common Mistakes That Undo the Strategy
The biggest is selling fundamentally good long-term holdings purely for tax reasons. If a stock is down 15 percent and you believe it will recover and double, the loss harvest may save you Rs 30,000 in tax but cost you Rs 5 lakh of forgone future appreciation if you fail to repurchase at the right level. Tax tail should not wag the investment dog. Second is not filing the ITR on time — late filing forfeits the carry-forward of capital losses, eliminating the multi-year value of harvested losses. Third is mixing up the character of losses (short-term versus long-term) when offsetting against gains, leading to suboptimal results. Fourth is harvesting in March under settlement pressure and missing the trade window. Fifth is harvesting in December and breaching the year-end without booking gains, then receiving a market rally in January-March that pushes you into a higher tax bracket.
Harvesting and Regime Choice
Capital gains are taxed identically under both the old and new tax regimes — the LTCG rate of 12.5 percent and the Rs 1.25 lakh exemption apply regardless of which regime you choose. So harvesting is beneficial under either regime. However, harvesting interacts with the regime decision in one subtle way: large realised LTCG can affect your overall income picture, particularly the breakeven analysis between regimes, especially if it pushes your total income across surcharge thresholds. Run your full year picture through the old vs new regime calculator after estimating realised capital gains, and review the old vs new decision framework for the income-band thresholds.
Documentation and Reporting
Each harvested transaction must be reported in your ITR — even when the loss does not generate immediate tax savings. Use ITR-2 (or ITR-3 if you have business income) and report capital gains in Schedule CG with full details: name of security, ISIN, dates of purchase and sale, sale proceeds, cost of acquisition (with indexation if applicable for non-equity), and the resulting gain or loss. Carry-forward losses must be reported in Schedule CFL and reconciled with prior-year ITRs. Maintain broker contract notes, demat statements, and bank statements for all transactions for at least eight years — the carry-forward window. The tax harvesting calculator models the year-end picture, and the capital gains tax calculator covers the per-transaction computation. Cross-link with the 80C optimization playbook when planning the broader tax picture.
Frequently Asked Questions
Does India have a wash-sale rule like the United States?
No. India has no statutory wash-sale rule that disallows losses when the same security is repurchased within a specified period. You can sell at a loss and buy back the next day with the loss fully claimed. However, the income tax department has general anti-avoidance powers under GAAR to disregard transactions whose sole purpose is tax avoidance with no commercial substance. The prudent practice is to separate the sell and buy by at least one trading day, or to repurchase a similar (not identical) security.
Can long-term capital losses offset short-term gains?
No. Long-term capital losses can only offset long-term capital gains. Short-term capital losses, however, can offset both short-term and long-term gains. This asymmetry makes short-term losses more valuable than long-term losses. When harvesting, prioritise booking short-term losses against short-term gains first (which are taxed at 20 percent for equity), then any remaining short-term losses against long-term gains (12.5 percent), and only then long-term losses against long-term gains.
How long can I carry forward unabsorbed capital losses?
Up to eight assessment years, provided you file your ITR on time within the original due date (not belated). Carry-forward losses retain their character — short-term remains short-term, long-term remains long-term — when used in future years. If you miss the filing deadline, the carry-forward right is forfeited entirely. This makes timely filing of returns critical for active harvesters.
Should I book Rs 1.25 lakh of LTCG every year even if I want to stay invested?
Yes, this is the "tax-gain harvesting" strategy and is mathematically optimal for most investors. By selling units that have appreciated and immediately repurchasing similar units, you realise gains within the Rs 1.25 lakh annual exemption (zero tax) and step up the cost basis on the new purchase. Future LTCG calculations are now from the higher base, reducing taxable gains at eventual full liquidation. Done annually for 20 years, this saves substantially more than the implementation cost.
My broker statement shows a "wash sale" warning. Should I worry?
No, broker compliance flags often borrow US terminology but do not reflect Indian tax law. India has no formal wash-sale rule, and your loss is fully claimable as long as the transaction has commercial substance. However, if you receive a tax notice questioning the harvested loss — typically as a sham-transaction allegation — engage qualified counsel.
