Tax loss harvesting India — how and when to do it
Learn how tax loss harvesting works in India — offset capital gains with losses to legally reduce your tax bill, with rules on 30-day waiting periods and c
Most people only think about their investments when they’re going up. But the years when your portfolio is bleeding red? Those are actually when you can do something smart with your losses — and legally cut your tax bill in the process.
That’s what tax loss harvesting is. And once you understand how it works in India, it becomes one of the few legal, zero-effort ways to keep more of what you earn.
What Tax Loss Harvesting Actually Means
When you sell a mutual fund or stock at a loss, that loss isn’t just painful — it’s also a tax asset. The Income Tax Act lets you use capital losses to offset capital gains. Less net gain means less tax. That’s the whole idea.
Say you’ve made ₹80,000 in long-term capital gains (LTCG) this year from selling some Nifty index fund units. LTCG on equity above ₹1 lakh is taxed at 10%. Now say you’re also sitting on an unrealised loss of ₹50,000 in an IT sector fund that’s been underperforming. If you sell that fund before March 31st, your net taxable gain drops to ₹30,000 — well below the ₹1 lakh LTCG exemption. Tax saved: ₹0 instead of ₹8,000.
That’s a real ₹8,000 back in your pocket for doing nothing except clicking “sell” at the right time.
The Rules You Actually Need to Know
India’s tax rules on this are specific, so get these right.
Short-term capital losses (STCL) — from assets held under 12 months for equity — can offset both short-term and long-term capital gains. Long-term capital losses (LTCL) can only offset long-term capital gains. So if you’re harvesting losses, a short-term loss is slightly more flexible than a long-term one.
The other big rule: if you can’t use the loss this year (because your gains aren’t high enough), you can carry it forward for up to 8 assessment years. But — and this matters — you have to file your ITR on time to claim this. Miss the deadline and the carryforward is gone.
One more thing: India doesn’t have a formal “wash sale” rule the way the US does. In the US, you can’t buy back the same asset within 30 days. In India, there’s no such restriction legally — you can sell your SBI Bluechip Fund units today, book the loss, and buy them back tomorrow if you want. Just be aware of exit loads and short-term tax implications if you’re doing this frequently.
When It Actually Makes Sense to Do This
Tax loss harvesting isn’t something to do just because you can. It makes sense in three specific situations.
First, when you have real capital gains this year. If your portfolio has grown and you’ve already sold something at a profit, look across your holdings for anything in the red. Even ₹20,000–₹30,000 in losses can meaningfully reduce your tax, especially if you’re in the 30% slab.
Second, near the end of the financial year — February and March. This is when you have a clear picture of your full year’s gains. Roshni works at a Pune-based startup, earns ₹1.1 lakh/month, and invested in a mix of Zerodha Coin and Groww over the past two years. By February she can see she’s sitting on ₹1.2 lakh in LTCG and a ₹40,000 unrealised loss in an ESG fund she bought during the 2021 ESG craze. Selling that ESG fund drops her taxable LTCG to ₹80,000 — below the ₹1 lakh exemption line. Tax liability: ₹0 instead of ₹2,000. Small, but free money.
Third, when you’re rebalancing anyway. If a fund has disappointed you and you were already planning to exit, doing it in a year with gains just makes the decision doubly sensible. Don’t hold a bad investment just to avoid booking a loss.

What to Watch Out For
The biggest mistake people make is over-optimising. If you’re selling and rebuying units just to harvest losses, you’re paying STT (Securities Transaction Tax) and potentially exit loads each time. On smaller amounts — say a ₹15,000 loss with an exit load of 1% — you might net very little benefit after friction costs.
Also remember: harvesting a loss doesn’t make a bad investment good. If you sell a poor-performing fund to book the loss and then rebuy it out of habit, you’ve achieved nothing. Use the reset as a chance to move into something better — a low-cost index fund, for instance, rather than an actively managed sector fund with a 1.8% expense ratio (that’s the annual fee the fund house takes, which compounds against you over time).
Frequently Asked Questions
Can I set off mutual fund losses against salary income?
No. Capital losses — short-term or long-term — can only be set off against capital gains. They cannot reduce your salary income or any other income head.
What happens if I don’t have any capital gains this year?
You can still harvest the loss and carry it forward for up to 8 assessment years, as long as you file your ITR before the due date. It’ll sit there waiting to offset future gains.
Is tax loss harvesting legal in India?
Completely legal. It’s a standard tax planning strategy explicitly permitted under the Income Tax Act. You’re not evading tax — you’re using the rules as written.
Does this work for debt mutual funds too?
Yes. Debt fund gains are now taxed as per your income slab (post the 2023 rule change). Losses from debt funds can be set off against other capital gains, so the same logic applies — though the numbers work differently since the old LTCG indexation benefit is gone.
Do I need a CA to do this?
Not necessarily. If your situation is straightforward — salaried income, a few mutual funds, no business income — you can track your gains on Kuvera or Zerodha Console and do this yourself. The platforms generate capital gains statements that make the numbers easy to read.
