Tax Loss Harvesting in India: How Booking Losses Can Save You ₹38,000

Your portfolio has ₹2.4 lakh in short-term gains and ₹1.9 lakh in losses sitting in a fund that didn't work out. Most people see the losses and feel bad. Smart investors see ₹38,000 in tax savings.

That losing fund in your portfolio isn't just a mistake. It's a tax asset — if you know how to use it. The technique is called tax loss harvesting, and it's one of the most underused strategies in Indian personal finance.

The idea is dead simple: you sell investments that are in a loss (on paper) to "book" that loss. This booked loss offsets your gains from other investments, reducing the tax you pay. And here's the part that makes India special — you can immediately rebuy the same fund. India has no wash sale rule.

Your portfolio stays the same. Your tax bill shrinks. That's it.

What is tax loss harvesting?

Every mutual fund investor has some funds that are up and some that are down. Most people ignore the down ones, hoping they'll recover. Tax loss harvesting says: use those losses right now to save money on tax.

Here's how it works:

1. You have Fund A with ₹2.4 lakh in gains (you owe tax on this).
2. You also have Fund B sitting at a ₹1.9 lakh loss (on paper — unrealized).
3. You sell Fund B to convert that paper loss into a real, booked loss.
4. This booked loss offsets your gains from Fund A.
5. Your taxable gain drops from ₹2.4 lakh to ₹50,000.
6. You immediately rebuy Fund B (or a similar fund). Your portfolio hasn't changed — but your tax bill has.

Key distinction: This is different from LTCG tax harvesting, which is about booking gains below the ₹1.25 lakh exemption to reset your cost basis. Tax loss harvesting is the opposite — you're booking losses to offset gains that are above the exemption. They're complementary strategies. Use both.

The tax rules you need to know

Capital gains tax on equity mutual funds in India (post Union Budget 2024):

Notice that STCG losses are more powerful than LTCG losses — they can offset both types of gains. This matters when you're deciding which losing fund to sell first.

The ₹38,000 save: a real example

Here is Rahul's situation, step by step.

Rahul's portfolio in March 2026:

• Mid-cap fund: ₹2.4 lakh in short-term gains (held 8 months, up 35%)
• Sectoral tech fund: ₹1.9 lakh in unrealized losses (bought during the tech rally, sector corrected 40%)

Without tax loss harvesting:

• Rahul's taxable STCG = ₹2,40,000
• Tax at 20% = ₹48,000
• The ₹1.9 lakh loss just sits there. On paper. Doing nothing.

With tax loss harvesting:

• Rahul sells the sectoral tech fund → books ₹1,90,000 in short-term capital loss
• This loss offsets his gains: ₹2,40,000 − ₹1,90,000 = ₹50,000 net taxable gain
• Tax at 20% on ₹50,000 = ₹10,000
• He immediately rebuys the same sectoral fund (or a similar tech fund)

Rahul's portfolio composition is identical. He still owns the mid-cap fund. He still has exposure to the tech sector. The only thing that changed is he paid ₹10,000 in tax instead of ₹48,000.

How to do it (step by step)

Step 1: Find your losing funds. Open your portfolio and look for funds that are currently in loss. Corpus shows this automatically when you upload your CAMS statement — it flags harvestable losses along with the tax impact.

Step 2: Check the holding period. Has the fund been held for less than 12 months (STCG loss) or more than 12 months (LTCG loss)? This determines what the loss can offset. STCG losses are more versatile — they can offset both STCG and LTCG gains.

Step 3: Sell the losing fund. Place a redemption order on your broker or AMC app. The loss is now "booked" — it moves from being a paper loss to a realized capital loss.

Step 4: Reinvest immediately. Buy back the same fund or a similar fund in the same category. Since India has no wash sale rule, there's no waiting period. Your portfolio allocation stays exactly the same.

Step 5: File it in your ITR. This is the step most people miss. You must report the capital loss in your income tax return. If you want to carry forward unabsorbed losses, you must file your ITR before the due date. Late filing = you lose the carry-forward benefit permanently.

The rules that matter

STCG loss is more powerful than LTCG loss. A short-term capital loss can offset both short-term and long-term capital gains. A long-term capital loss can only offset long-term gains. If you have the choice, harvest STCG losses first — they give you more flexibility.

You must file your ITR on time. Section 139(1) deadline is July 31 for most individuals. If you file a belated return under Section 139(4), you cannot carry forward capital losses. This is non-negotiable.

Losses carry forward for 8 assessment years. If your losses exceed your gains this year, the remaining loss carries forward. You can use it to offset gains in any of the next 8 years. But again — only if you filed on time in the year you booked the loss.

India has no wash sale rule. In the US, if you sell a stock at a loss and rebuy it within 30 days, the loss is disallowed. India has no such restriction. You can sell your mutual fund at 2 PM and rebuy it at 2:01 PM. The loss is still valid.

When NOT to harvest losses

Exit load applies. Most equity mutual funds charge a 1% exit load if you redeem within 1 year. If your fund is 9 months old and in a ₹15,000 loss, the exit load on redemption might eat into your tax savings. Do the math first.

The fund is still fundamentally sound. If your large-cap fund dropped 10% because the entire market corrected, that's not a reason to sell. The fund isn't broken — the market is cycling. Wait for a natural rebalancing window. Don't sell a good fund purely for tax reasons unless you can rebuy immediately.

Your total gains are below ₹1.25 lakh. If your long-term gains are under the ₹1.25L exemption, you don't owe LTCG tax anyway. Harvesting LTCG losses in this case is pointless — there's nothing to offset. (STCG losses may still be useful if you have STCG gains, since there's no exemption for STCG.)

Transaction costs eat the savings. STT (Securities Transaction Tax) applies on both the sale and purchase. On very small amounts (<₹20,000 in losses), the STT + exit load + hassle may not justify the tax saving. Focus on losses of ₹50,000+ for meaningful impact.

Tax loss harvesting vs tax gain harvesting — use both

These are two different techniques, and smart investors use both in the same financial year:

The ideal annual playbook:

• November–December: Do gain harvesting. Sell and rebuy funds with long-term gains up to ₹1.25L to reset your cost basis and use the tax-free exemption.
• January–March: Do loss harvesting. Review your full-year gains, find offsetting losses, and book them before March 31.

Combined, these two strategies can save a typical equity investor ₹15,000–50,000 per year. Every year. Compounded over a decade, that's a meaningful chunk of your portfolio.

What is tax loss harvesting in mutual funds?

Tax loss harvesting means selling mutual fund units that are currently at a loss to "book" that loss officially. This booked loss can then offset your capital gains from other investments, reducing the total tax you owe. You can immediately reinvest in the same fund or a similar one — India has no wash sale rule, so there's no mandatory waiting period.

Is there a wash sale rule in India?

No. India has no wash sale rule. Unlike the US (where you must wait 30 days before rebuying the same security), Indian tax law allows you to sell an investment at a loss and immediately repurchase the same fund. This makes tax loss harvesting significantly simpler and more effective in India.

Can I carry forward capital losses in India?

Yes. Unabsorbed capital losses (both short-term and long-term) can be carried forward for up to 8 assessment years. However, you must file your income tax return on time (before the due date under Section 139(1)) to claim this carry-forward benefit. If you file a belated return, you lose the ability to carry forward the loss.

Should I sell a good fund just to harvest the loss?

Not necessarily. If the fund is fundamentally sound and the loss is temporary (due to a market correction), you may want to hold. Tax loss harvesting works best when you have a fund that has underperformed and you were planning to exit anyway — or when you can sell, book the loss, and immediately rebuy the same fund. In the second case, your portfolio stays identical, but you've locked in a tax benefit for free.

When is the best time to do tax loss harvesting?

The best time is January–March, before the financial year ends on March 31. This gives you visibility into your full-year gains and lets you offset them with losses before the deadline. However, if a fund drops sharply mid-year and you have gains to offset, there's no reason to wait. Pair this with LTCG gain harvesting (which works best in November–December) for a complete year-end tax strategy.
