Tax-Loss & Exemption Harvesting Before 31 March

Most investors get to the end of the financial year and do nothing — not out of laziness, but because of two quiet, understandable fears. The first: selling a holding feels like giving up on it, like admitting a mistake. The second is worse because you can't even feel it — nobody ever told you there was free money on the table every March, so you can't miss what you don't know you're leaving behind.

Both fears cost real rupees. There is a ₹1,25,000 tax-free allowance on long-term equity gains that renews every single financial year and vanishes if you don't use it. And a holding you're sitting on at a loss can be turned into a tax saving instead of a quiet regret. Neither is a loophole or a trick — both are written plainly into the law, and you run them yourself, in your own app, in minutes. This lesson is the investor's playbook for the last weeks before 31 March.

There are exactly two moves, and they point in opposite directions — one for your winners, one for your losers — but they share a single cut-off, 31 March, the last day of the financial year.

1. Exemption harvesting (for your winners): realise up to ₹1,25,000 of long-term gains, pay ₹0 tax on them because they fit inside the yearly exemption, and immediately re-buy. You end up owning the same fund, but with a higher cost base — so less of your gain is left to be taxed later. Do it every year and the saving compounds.
2. Loss harvesting (for your losers): sell a holding that's underwater to book the loss, and set that loss against gains you've already realised this year — cutting the tax on those gains. Anything left over isn't wasted — it's carried forward to offset future years' gains (we'll see for how long).

The first play uses an allowance that expires yearly. The second turns a decline you've already suffered into something useful. Both are legal, both are repeatable, and — because India has no wash-sale rule — both let you keep the exact position you want. We'll take them one at a time, on Suresh, Tanvi and the Iyers, then hand you a planner to run your own numbers.

Here is the fact that quietly costs people the most: the ₹1,25,000 exemption on long-term equity gains is not a lifetime figure and it does not accumulate. It is a fresh allowance handed to you at the start of every financial year, and if you don't use it by 31 March, it's gone — it does not roll over into next year.

Put a number on the waste. If you skip a year's allowance, you've thrown away the tax you could have saved on ₹1,25,000 of gains — that's ₹1,25,000 × 12.5% = ₹15,625. Not a fortune in one year, but it's ₹15,625 you'll never get back, and it repeats. Miss five years and you've quietly forgone up to ₹78,125. This is the term for using it: exemption harvesting — deliberately realising gains up to the free limit so the allowance is spent, not lapsed.

Suresh Menon, 55, a CA and consultant in Kochi on ₹40,00,000 a year (a 30% slab plus surcharge), has the most to gain, because he has a large taxable equity book inside his roughly ₹1.8 crore. Illustratively, that book is worth about ₹60,00,000 with ₹20,00,000 of embedded long-term gains sitting inside it — gains he'll owe tax on the day he sells. He earmarks a ₹12,50,000 slice to unwind slowly, and runs the habit.

Each 31 March he sells just enough to realise ₹1,25,000 of long-term gain — right up to the free limit — pays ₹0 tax, and buys the same fund straight back. That single act does two things: it 'spends' this year's allowance, and it lifts his cost base — the purchase price the taxman subtracts from his eventual sale price — by ₹1,25,000, because he re-bought at today's higher price. Repeat it for ten years and the whole ₹12,50,000 slice moves out of the taxable column — tax-free.

The right-hand panel is the point. If Suresh never harvested and instead sold that ₹12,50,000 of gain in a single year, only one ₹1,25,000 exemption would apply — leaving ₹11,25,000 taxed at 12.5%, a bill of ₹1,40,625. Spread over ten annual harvests, the same gain costs ₹0. The ₹1,40,625 saving is simply nine yearly allowances (₹15,625 each) he'd otherwise have let expire. Same funds, same gain — one route just used the free pass every year.

The words 'cost base' do the heavy lifting, so let's make them concrete. Your cost base (or 'cost of acquisition') is what the taxman treats as your purchase price — your gain is the sale price minus this. When Suresh sells at today's price and re-buys at that same price, his new cost base is today's price. The gain he already realised is settled (and, being within the exemption, taxed at ₹0); everything above today's price is fresh gain that will only be taxed if the fund rises further.

There is one honest catch to respect. The units Suresh re-buys are, in the eyes of the law, a new purchase — so they start a fresh 12-month clock and must be held more than a year again to qualify as long-term. For someone harvesting once a year and holding for decades, that's no problem at all; he's never selling those units within twelve months anyway. But it's why you harvest deliberately, not restlessly.

It's tempting to file this under 'things rich people do'. It isn't. The allowance is the same ₹1,25,000 for everyone with equity, so anyone with gains can spend it.

Tanvi Kapoor, 28, in Gurugram on ₹12,00,000, has just deployed part of her ₹50,00,000 inheritance into equity funds — her first-ever portfolio. Her advantage is timing: she can build the harvest habit from day one, so gains never pile up into a single taxable lump the way Suresh's did. Each year she realises a slice of her long-term gains up to the free limit, re-buys, and keeps her cost base climbing with the market. She never has to face a ₹1,40,625 reckoning, because she never lets the gains accumulate.

The Iyers — Rohan and Meera in Bengaluru, household ₹30,00,000, old regime — have just a few equity mutual funds, with (illustratively) ₹1,50,000 of long-term gain built up. If they sold all ₹1,50,000 in one year, ₹25,000 would spill past the exemption and cost ₹3,125. Instead they realise ₹1,25,000 this year (₹0 tax) and the last ₹25,000 next year (also ₹0) — the whole gain comes out tax-free, saving them ₹3,125. Small, but it's their money, and it's free.

Now the second play, and the second fear. Somewhere in most portfolios sits a holding that's down — a fund that fell, a stock that never recovered. The instinct is to hold it and hope, because selling feels like locking in the mistake, turning a paper loss into a real one. That instinct is exactly backwards for tax.

A paper loss — an unrealised loss you're just holding — does nothing for you. It doesn't lower your tax; it doesn't do anything until you act. The moment you sell, you book the loss, and a booked loss becomes a tax asset: it can be set against gains you've realised elsewhere, cutting the tax on those gains rupee-for-rupee. This is loss harvesting (also called tax-loss harvesting): deliberately selling a loser to book its loss so it can cancel your gains.

And here's the reassurance that defuses the fear: if you still believe in the holding, you don't have to give it up. Because India has no wash-sale rule, you can buy it straight back after selling. You keep the position and you keep the tax saving. The only thing you surrender is the paper loss that was doing nothing for you.

One rule governs everything in loss harvesting, and it's asymmetric — which is the whole trick. A short-term loss is versatile: it can be set against either a short-term gain (taxed at 20%) or a long-term gain (taxed at 12.5%). A long-term loss is fussy: it can only be set against long-term gains — never short-term ones.

The practical consequence is a rule of thumb worth memorising: your short-term losses are precious, because they're flexible — spend them on your most heavily taxed gains first, the 20% short-term ones. Save your long-term losses for long-term gains, because that's the only place the law lets them work. Aim your losses badly and you save less tax for the exact same losses.

And notice the box in the corner of the map: any loss bigger than this year's gains isn't wasted. The unused part is carried forward — but that's a beat of its own, so hold that thought for two sections.

Back to Suresh, but a different year. This time he's realised gains he can't undo — during the year he sold some winners and booked STCG of ₹4,00,000 (taxed at 20%) and LTCG of ₹6,00,000 (taxed at 12.5%, after his ₹1.25L exemption leaves ₹4,75,000 taxable). Left alone, his capital-gains tax is ₹80,000 + ₹59,375 = ₹1,39,375. But he's also holding two losers he's been avoiding.

He books them before 31 March: a short-term loss of ₹2,00,000 and a long-term loss of ₹3,00,000. Following the rulebook, he aims the short-term loss at the 20% short-term gain (the higher-taxed one — the flexible loss goes where it saves most), and the long-term loss at the long-term gain (its only permitted home).

The saving is ₹77,500, and it decomposes cleanly: the ₹2,00,000 short-term loss saved ₹40,000 (2,00,000 × 20%), and the ₹3,00,000 long-term loss saved ₹37,500 (3,00,000 × 12.5%). Had he lazily aimed the short-term loss at the long-term gain instead, that ₹2,00,000 would have saved only ₹25,000 — ₹15,000 less, for no reason. Routing matters. And he still owns his winners; only the losers left the book — and even those he can buy straight back.

What if your loss is bigger than this year's gains — or you have no gains to cancel at all? This is where the corner box on the map earns its place. A loss you can't fully use this year isn't lost; the leftover is carried forward for up to 8 years, waiting for future gains. A carried long-term loss can only meet future long-term gains; a carried short-term loss can meet either.

Tanvi shows the pure case. She's new, so she has almost no realised gains — just a small ₹50,000 short-term gain from tidying up her portfolio. But one of her funds dropped, and she's holding an unrealised short-term loss of ₹2,00,000. If she books it now, ₹50,000 of it cancels her ₹50,000 gain (saving ₹10,000, at 20%), and the remaining ₹1,50,000 is banked — carried forward for up to 8 years to offset gains she hasn't even made yet.

So the lesson from Tanvi flips the fear entirely: booking a loser with no gains to offset isn't pointless — it banks a saving for the future. A loss you never book is a loss you can never use.

Both plays share the same clock, and it's unforgiving in one direction: the sale must fall inside the financial year (which ends 31 March) to count against this year's gains and use this year's allowance. Sell on 1 April and it belongs to the next year instead. This is why harvesting is a habit you repeat every year, not a thing you do once.

There are really two deadlines to hold in your head, and it's easy to confuse them. The first is 31 March — the harvest cut-off, when the sale (and any re-buy) must happen for it to count this year. Leave a couple of days for settlement, so don't wait for the 31st itself. The second is your return's due date, months later — the deadline to file if you want to bank a carry-forward loss. Miss the first and this year's allowance lapses; miss the second and your carried loss is forfeited.

In some countries (the United States, for one) a 'wash-sale rule' disallows the loss if you re-buy the same security within 30 days — it stops you booking a loss while keeping the position. India has no such rule for listed equity and equity funds. You can sell to book a loss (or to harvest the exemption) and buy the very same holding back, and the loss still counts and the exemption still applies. This is what makes both plays practical: you never have to change what you own to get the tax benefit.

One practical wrinkle, worth knowing so you do it cleanly. For a mutual fund, this is effortless: you redeem the units (which always books the gain or loss) and buy fresh units, usually at the next day's NAV — the harvest is clean and automatic. For direct stocks, a same-day sell-and-rebuy of the same quantity can be netted by your broker as an intraday trade, in which case the delivery holding never actually moves and the gain or loss may not register the way you intend. The simple fix is to re-buy the next trading day — you carry one night of market movement, but the sale settles cleanly as a real transaction. Either way, no wash-sale rule stands in your way.

Where you find it, and what it is

You don't have to guess your numbers — the whole picture arrives in one document. Every broker (Groww, Zerodha and the rest) and the mutual-fund registrars (CAMS, KFintech) generate a Capital Gains Statement: an online report, downloadable as a PDF or viewed in-app, that lists what you've realised this financial year and — usually alongside your holdings — what's still unrealised. It's the same statement Lesson 41 used to rank investments after tax; here we read it for a different decision — the harvest. Below is a partial specimen on Suresh's book.

Field by field, on Suresh's numbers

• Realised — short-term capital gain (§111A): +₹4,00,000. Gains on units sold within 12 months this year; taxed at 20%. This is what a booked short-term loss can cancel.
• Realised — long-term capital gain (§112A): +₹6,00,000. Gains on units held over 12 months; taxed at 12.5% above the exemption.
• less: §112A exemption applied: −₹1,25,000. The statement shows the free allowance being subtracted from his long-term gains — this is the exemption at work.
• Taxable long-term gain so far: ₹4,75,000. What's left after the exemption (₹6,00,000 − ₹1,25,000) — before any loss harvesting.
• Your ₹1.25L exemption → Headroom to harvest tax-free: ₹0. The first line this lesson reads. Suresh has already realised more than ₹1.25L of LTCG, so his free pass is spent — his play this year is loss harvesting, not exemption harvesting. (A smaller investor with under ₹1.25L of realised LTCG would see a positive number here — room to harvest more gain tax-free.)
• Still held — Large-cap index fund, long-term: +₹9,20,000 unrealised. A winner; it would be exemption-harvest material if he had headroom (he doesn't, this year).
• Still held — Flexi-cap fund, short-term: −₹2,00,000 unrealised. A short-term loser — the harvestable STCL. Aim it at the 20% gain.
• Still held — Thematic fund, long-term: −₹3,00,000 unrealised. A long-term loser — the harvestable LTCL. It can only meet his long-term gain.
• Still held — Mid-cap fund, long-term: +₹4,80,000 unrealised. Another winner, left alone.
• If you book the two losers before 31 Mar → Tax saved: ₹77,500. The second line this lesson reads — the statement doing the arithmetic of the loss-harvest play for him.

Notice something in Suresh's statement: his exemption headroom was ₹0. That's not a mistake — it's the pattern. Which play applies to you depends on where your realised gains already stand this year, and the two situations are almost mirror images.

Big realisers usually harvest losses; steady long-term holders usually harvest the exemption; many people do a bit of both. You don't have to decide in the abstract — the planner at the end of this lesson reads your position and tells you which play, and how much, in seconds.

If you've ever wondered what a private wealth manager actually does for a taxable client each year that justifies the fee, this is near the top of the list — and it's entirely doable yourself.

The move is exactly the two plays you've just learned, run every March. The logic is that both are free, legal and repeatable. The do-it-yourself version is you, in your broker app, selling and buying back — no PMS wrapper, no fee. And the tell is sharp: an adviser who never once mentions your yearly ₹1.25L allowance, or only 'harvests' when you ask, is leaving your money on the table while charging you. A fee-only, SEBI-registered adviser who runs this every March earns their keep; a distributor who sells you funds but skips the free ₹15,625 does not.

Because harvesting is legal and simple, it's easy to imitate — and the dangerous imitation sounds almost identical. There's a critical line between the real play and a crime, and it comes down to a single word: whose loss is it?

Real harvesting sells your own genuine holdings at the real market price — you book whatever gain or loss they actually show. A scam sells you a loss: a pre-arranged 'accommodation' entry, a rigged penny-stock round-trip, a bogus contract note, promised as a guaranteed number in advance. That's not tax planning; it's tax evasion, caught by §270A with a penalty of 50% to 200% of the tax evaded, plus interest and possible prosecution — and your own data (the AIS, scrip-wise reporting) already flags manufactured losses. No ₹15,625 or ₹77,500 saving is worth that. If someone is selling you a loss, guaranteeing a number, or doing it off-market for a cut, walk away — and report it (SEBI SCORES for mis-selling; cybercrime 1930 for fraud; the Income-Tax department for an evasion scheme).

Maybe, reading all this, you're realising you've let the allowance lapse for years, or you've been holding a loser since 2021 hoping it'll 'come back' while its loss did nothing for you. That's not carelessness — the rules aren't advertised, and holding a loser can feel like patience rather than a mistake.

The lapsed years are genuinely behind you — as much as ₹78,125 over five missed years — and there's nothing to do but let them go. But this year's ₹15,625 is still live, and a fresh allowance arrives every 31 March; set a March reminder and the habit starts now. And that loser you're still holding? You can harvest it today — book the loss and bank it for up to 8 years. The years you held it weren't wasted; the loss is still yours to use. Then do one more thing: tell someone the allowance resets every year, because most people genuinely don't know.

Now run your own position. Enter this year's realised gains, the long-term winners you could still harvest, and the losers you could book. The planner finds your exemption headroom (how much more gain you can realise tax-free), routes your losses optimally, and shows the tax saved and any carry-forward — reproducing the three situations exactly: Suresh's ₹77,500 saved by booking losers, Tanvi's ₹1,50,000 banked as carry-forward, and the Iyers' full ₹1,25,000 of exemption headroom. Load each to see them, then clear it and type your own.

Watch what changes as you type. Lower your realised LTCG below ₹1,25,000 and exemption headroom appears — that's the exemption-harvest play lighting up. Raise your booked losses above your gains and a carry-forward number appears — that's the bank-it-for-later play. The planner is just the rulebook doing your arithmetic; the decisions (which funds, when) are still yours.

Two plays, one deadline. Before 31 March, spend your ₹1.25L allowance on your winners so it doesn't lapse, and book your losers to cancel your gains (or bank them for up to 8 years). Both are free, legal and repeatable, and India's missing wash-sale rule means you never have to change what you own. On a taxable book, this single March habit is worth more, more reliably, than most of the stock-picking people agonise over.

Glossary — the terms this lesson introduced

• Exemption harvesting — realising long-term equity gains up to the ₹1,25,000 yearly free limit (so the tax is ₹0) and re-buying, to spend an allowance that would otherwise lapse and reset your cost base higher.
• Tax-loss harvesting — deliberately selling a holding at a loss to book that loss, so it can be set against your capital gains and cut the tax on them.
• Cost-base reset — the effect of selling and re-buying: your recorded purchase price rises to today's price, shrinking the gain that's still exposed to future tax.
• Set-off — subtracting a capital loss from a capital gain before tax is worked out. STCL can set off against STCG or LTCG; LTCL only against LTCG.
• STCL / LTCL — a short-term capital loss (holding ≤12 months) / a long-term capital loss (holding >12 months); the two loss types, with different set-off rights.
• Carry-forward — keeping an unused capital loss on your record for up to 8 years to offset future gains — allowed only if you file your return by its due date.
• The 31-March deadline — the end of the financial year; a harvest sale must fall on or before it to count this year and use this year's allowance.
• No-wash-sale rule (India) — the absence of any Indian law disallowing a loss (or harvest) when you re-buy the security you just sold; you can sell and buy straight back.
