Tax-Loss Harvesting: Cutting Capital Gains Tax Legally

Most investors think of capital losses as pure bad news. They are — but the tax code offers a consolation prize. If you have realised gains during the year, you can deliberately sell some of your loss-making holdings to book those losses and cancel out the gains, shrinking your capital gains tax bill. This practice is called tax-loss harvesting, and in India it is entirely legal, openly permitted by the Income Tax Act.

What makes harvesting especially attractive here is the absence of a "wash-sale" rule. In the United States you cannot claim a loss if you buy the same security back within 30 days. India has no such restriction, which gives investors meaningful flexibility. This guide explains the set-off rules, the carry-forward limits, the equity exemption, and how to harvest cleanly — with a worked example in rupees.

What Tax-Loss Harvesting Actually Is

When you sell an investment for less than you paid, you realise a capital loss. The tax law lets you use that loss to reduce capital gains you have made elsewhere. Tax-loss harvesting is the deliberate act of selling depressed holdings before the financial year ends, so the realised loss offsets your realised gains and lowers the tax due.

The key word is realised. A loss on paper does nothing for your taxes. You must actually sell the holding to convert a notional loss into a deductible capital loss. The same is true of gains — only realised gains are taxed, and only realised losses can offset them.

Harvesting does not make the underlying loss disappear from your portfolio's economics; you still lost money on that investment. What it does is recover some of the sting by reducing the tax on your winning positions.

The Set-Off Rules You Must Respect

This is where harvesting gets technical. Capital losses cannot offset just anything — there is a strict hierarchy:

Loss type	Can offset STCG?	Can offset LTCG?	Can offset salary / other income?
Short-term capital loss (STCL)	Yes	Yes	No
Long-term capital loss (LTCL)	No	Yes	No

Two principles fall out of this:

• Short-term losses are more valuable. A short-term capital loss can absorb both short-term and long-term gains, so it is the more flexible tool.
• Long-term losses are restricted. A long-term capital loss can only be set off against long-term capital gains, never against short-term gains.

And neither type of capital loss can be set off against your salary, business, rental, or interest income. Capital losses live in their own silo and can only meet capital gains.

Carry-Forward: Losses Don't Expire Immediately

If your losses exceed your gains this year, the leftover does not vanish. You can carry forward unabsorbed capital losses for up to 8 assessment years and set them off against capital gains in those future years, applying the same set-off rules.

But there is a non-negotiable condition: you must file your income tax return on or before the due date for the year in which the loss arose. Miss the deadline and file a belated return, and you forfeit the right to carry that capital loss forward — though you can still set it off within the same year. This is one of the most expensive consequences of late filing, discussed further in belated returns. Filing on time is the price of preserving your losses.

The Equity LTCG Exemption Changes the Maths

Equity shares and equity mutual funds get a special break: long-term capital gains up to ₹1.25 lakh per financial year are exempt from tax. LTCG above that is taxed at 12.5%. Short-term gains on equity are taxed at 20%.

This exemption interacts with harvesting in a useful way. If your equity LTCG for the year is below ₹1.25 lakh, you owe no tax on it anyway — so harvesting losses against that gain would waste the loss. A smarter move in low-gain years is to harvest gains, not losses: book just enough long-term gains to use up the ₹1.25 lakh exemption, resetting your cost base higher tax-free. Harvest losses in the years your gains genuinely exceed the exemption.

A Worked Example in Rupees

Consider Priya, an equity investor reviewing her portfolio in March 2026, near the end of FY 2025-26. Her realised gains so far:

• Short-term capital gain on a stock sold within months: ₹1,50,000 (taxed at 20%)
• Long-term capital gain on equity mutual funds held over a year: ₹2,00,000 (first ₹1.25 lakh exempt, rest at 12.5%)

She also holds two beaten-down positions sitting at a loss:

• Stock A, held 5 months, currently ₹80,000 below cost (a short-term loss if sold)
• Stock B, held 3 years, currently ₹70,000 below cost (a long-term loss if sold)

Before harvesting — her tax:

• STCG: 20% × ₹1,50,000 = ₹30,000
• LTCG: ₹2,00,000 − ₹1,25,000 exemption = ₹75,000 taxable; 12.5% × ₹75,000 = ₹9,375
• Total ≈ ₹39,375 plus 4% cess (≈ ₹40,950)

She harvests both losses by selling A and B:

• Short-term loss ₹80,000 (from Stock A) — flexible, can offset either gain. Set it against her STCG first: ₹1,50,000 − ₹80,000 = ₹70,000 STCG remaining.
• Long-term loss ₹70,000 (from Stock B) — can only offset LTCG. Set it against her LTCG: ₹2,00,000 − ₹70,000 = ₹1,30,000 LTCG remaining.

After harvesting — her tax:

• STCG: 20% × ₹70,000 = ₹14,000
• LTCG: ₹1,30,000 − ₹1,25,000 exemption = ₹5,000 taxable; 12.5% × ₹5,000 = ₹625
• Total ≈ ₹14,625 plus cess (≈ ₹15,210)

Tax saved by harvesting: roughly ₹40,950 − ₹15,210 = ₹25,740.

Because India has no wash-sale rule, Priya can buy Stock A and Stock B back if she still believes in them — ideally a day later or via a similar fund — keeping her market exposure broadly intact while banking the tax benefit. She has effectively used her losing positions to slash the tax on her winners by over half.

Note how the asymmetry mattered: her short-term loss could have offset the LTCG too, but it was more efficient to use the flexible short-term loss against the short-term gain (taxed at the higher 20%) and the restricted long-term loss against the LTCG.

Doing It Cleanly: The No-Wash-Sale Advantage and Its Limits

India's lack of a wash-sale rule is a genuine edge — you can realise a loss and rebuild the position. But treat it sensibly:

• Selling and rebuying the exact same quantity of the same scrip on the same day, with no real change in your position, looks like a pure tax device and can be questioned.
• Cleaner approaches: wait a day or two before repurchasing; buy a similar but not identical fund or stock; or simply accept a brief gap in exposure.
• Mind transaction costs — brokerage, STT, exchange charges and the bid-ask spread. If the tax saved is smaller than the round-trip cost, harvesting is not worth it.
• Watch FIFO for mutual funds: redemptions match the oldest units first, which affects whether the realised loss is short- or long-term. See tax on mutual funds for how FIFO works.

Timing: Why Harvesting Is a Year-End Discipline

Tax-loss harvesting is most effective when done deliberately in the final weeks of the financial year, once you can see the full picture of your realised gains. By February or March you know:

• How much STCG and LTCG you have actually booked.
• How much of your equity LTCG falls within the ₹1.25 lakh exemption.
• Which holdings are sitting at a loss and could be harvested.

This lets you harvest precisely the amount of loss needed to offset the taxable portion of your gains, rather than over-selling. Over-harvesting has a hidden cost: if you book more losses than you have gains, the surplus only carries forward — useful, but it means you sold a holding (and possibly disrupted a long-term position) for a benefit you cannot use this year.

A second timing nuance concerns mutual fund holding periods. Because equity funds turn long-term after 12 months and most other assets after 24 months, a holding that is just short of the long-term threshold may be worth keeping a few more weeks if you intend to harvest a gain, or selling now if you want a flexible short-term loss. The interplay between the holding-period clock and the type of loss you want to generate rewards a careful look at each lot's purchase date.

Harvesting Beyond Equities

The set-off rules apply across all capital assets, not just shares. You can harvest losses on:

• Debt mutual funds, gold ETFs, and other securities.
• Property — though large, lumpy, and rarely sold purely for harvesting.
• Unlisted shares and other capital assets.

A short-term loss on a debt fund, for instance, can offset a short-term gain on a stock, because both are short-term capital items. This cross-asset flexibility is why a year-end review should cover your entire portfolio of capital assets, not just your equity holdings. Just remember the one hard rule that never bends: long-term losses can only meet long-term gains, whatever the asset.

Reporting Harvested Losses

Harvested losses must be reported in your ITR under the capital gains schedule, with the set-off worked out there. If you have losses to carry forward, the return captures them in the carry-forward schedule. Because losses and gains are reported to the department and appear in your Annual Information Statement, reconcile your broker's capital gains statement against the AIS before filing. Keep your contract notes and the capital gains statement with your other filing paperwork — the tax document checklist covers what to retain.

Above all, file on time if you want to carry losses forward.

Common Mistakes

Setting a long-term loss against short-term gains. Not allowed. Long-term losses meet only long-term gains. Plan your sales around this.

Harvesting losses against equity LTCG that was already exempt. If your equity LTCG is under ₹1.25 lakh, it is tax-free anyway — offsetting it with a loss wastes the loss. Save losses for years your gains exceed the exemption.

Filing late and losing the carry-forward. A belated return forfeits the right to carry capital losses into future years. The one habit that protects your losses is filing by the due date.

Overdoing the same-day buy-back. While there is no wash-sale rule, an identical same-day sell-and-rebuy of the same units invites scrutiny. Add a small gap or use a similar instrument.

Ignoring transaction costs. Brokerage, STT and spreads can eat the benefit on small harvests. Run the numbers before churning.

Forgetting capital losses can't touch salary. Capital losses only offset capital gains, never your salary or interest income. Do not expect a loss to reduce tax on your pay.

What to Do Next

• Before 31 March, pull your realised capital gains for the year and identify whether they are short- or long-term.
• Scan your portfolio for holdings sitting at a loss and decide which to harvest, matching loss type to gain type for maximum efficiency.
• In low-gain years, consider harvesting gains up to the ₹1.25 lakh equity exemption instead, to reset your cost base tax-free.
• If you still want the position, rebuild it a day or two later or via a similar instrument — India's no-wash-sale rule allows it.
• File your ITR on time so any unused loss carries forward for up to 8 years, and reconcile everything against your AIS first.

Tax-loss harvesting will not turn a losing investment into a winner, but it is one of the few entirely legal levers that directly cuts your capital gains tax. Used deliberately around year-end, and respecting the set-off rules, it can save a meaningful sum every year.
