Summary: As tax season nears, many mutual fund investors will be looking to save on capital gains tax through ‘tax-loss’ harvesting. However, with the 2024 change in capital gains tax, is tax-loss harvesting still useful? We find out.

Yes, tax-loss harvesting still works in 2026. But it is no longer something you do automatically every March. It adds value only when two conditions are true: you have real taxable gains to offset, and the tax saved is meaningfully larger than the cost of harvesting.

The key shift is that equity mutual fund tax rates are now sharper and more consequential. Equity short-term capital gains (STCG) are taxed at 20 per cent for transfers on or after July 23, 2024. Equity long-term capital gains (LTCG) under Section 112A are taxed at 12.5 per cent, but only on gains above Rs 1.25 lakh.

That means the decision is now more mathematical than it used to be. In most cases, you can estimate the potential savings in a few minutes and decide whether harvesting is worth the effort.

One clarification before we begin: tax-loss harvesting does not improve investment returns. It does not fix a weak fund or a poor asset allocation. It simply changes the tax outcome of moves you were going to make anyway, or occasionally makes a tactical sell-and-buy-back worthwhile.

What tax-loss harvesting is

Tax-loss harvesting means booking a capital loss by redeeming mutual fund units that are worth less than what you paid for them. That loss can then be set off against your taxable capital gains in the same financial year or carried forward to future years.

Two points matter specifically for mutual funds.

A switch counts as a redemption for tax purposes: When you switch from one scheme to another, even within the same AMC, the switch-out leg is treated as a sale. It can therefore trigger capital gains or losses exactly as a redemption would.

The loss must be booked before March 31: If you want to use the loss in the current financial year, the transaction must be completed before March 31. Once the year ends, you cannot go back and harvest the loss.

The set-off rules that make harvesting possible

Capital loss set-off works under a few clear rules:

• A short-term capital loss (STCL) can be set off against both STCG and LTCG.
• A long-term capital loss (LTCL) can be set off only against LTCG.
• Capital losses cannot be set off against salary, interest, or any other income head.
• Unused losses can be carried forward for up to eight assessment years.

However, carry-forward is allowed only if you file your ITR before the due date for that financial year. If you miss the deadline, the right to carry forward the loss is lost.

The decision framework: Is it worth doing this year?

Before harvesting losses, work through these five questions. If the answer to any of the first three is no, harvesting is usually pointless.

#1 Do you actually have taxable gains this year?

Equity LTCG below Rs 1.25 lakh attracts no tax under Section 112A.

If your total equity LTCG for the year is, say, Rs 90,000, harvesting losses to offset it saves you nothing.

Similarly, if you have no equity STCG, an STCL has limited immediate use, although it can still be carried forward.

#2 Can the loss actually be set off against your gains?

STCL is the more flexible type of loss because it offsets both STCG and LTCG.

LTCL is more restrictive. It can offset only LTCG. If most of your gains are short-term but your losses are long term, the set-off may not work the way you expect.

#3 Is the tax saving larger than the cost of harvesting?

Harvesting is not free. Your costs include:

• Exit load, if the fund still levies one on your units
• The risk of being briefly out of the market (usually small if you re-enter quickly, but NAV cut-off timing matters)
• The holding-period reset, which is often the most overlooked cost

A quick estimate of gross saving:

• If the loss offsets STCG, you save 20 per cent of the loss used.
• If it offsets LTCG above Rs 1.25 lakh, you save 12.5 per cent of the loss used.

Your savings must comfortably exceed these costs.

#4 Will resetting the holding period hurt you later?

This is the most commonly overlooked issue.

When you sell and re-buy units, even of the same fund on the same day, the new units start a fresh holding period.

If you redeem those units within the next 12 months, the gain will be taxed as STCG at 20 per cent, not LTCG at 12.5 per cent. In other words, you may save a little tax today but pay more tax later.

Harvesting is generally safer when:

• You are already well into long-term territory and plan to stay invested, or
• You were planning to exit the position anyway.

#5 Are you harvesting to maintain exposure or to exit?

If you are exiting a fund you no longer want, harvesting is simply smart accounting. You book the loss on the way out.

If you want to maintain your market exposure after harvesting, you must decide whether to:

• Re-buy the same fund, or
• Switch to a similar fund

Re-buying the same fund preserves exposure most cleanly but resets the holding period. Switching to a close substitute (same benchmark or style) produces a similar exposure but introduces small tracking differences.

Three scenarios: When harvesting helps, and when it doesn’t

Scenario 1: Harvesting adds real value

Your equity LTCG for the year (Section 112A): Rs 3 lakh
Your available STCL: Rs 1,00,000

Without harvesting

Taxable LTCG = Rs 3 lakh − Rs 1.25 lakh = Rs 1.75 lakh
Tax = 12.5 per cent × Rs 1.75 lakh = Rs 21,875

With harvesting

Net LTCG after set-off = Rs 3 lakh − Rs 1 lakh = Rs 2 lakh
Taxable LTCG = Rs 2 lakh − Rs 1.25 lakh = Rs 75,000
Tax = 12.5 per cent × Rs 75,000 = Rs 9,375

Tax saved = Rs 12,500 (before exit load and other frictions)

Why the saving is at 12.5 per cent and not 20 per cent: the STCL reduces your LTCG, not your STCG. Therefore, the saving occurs at the LTCG rate of 12.5 per cent. If the loss had reduced STCG instead, the saving would have been at 20 per cent.

Scenario 2: Harvesting is pointless

Your equity LTCG for the year: Rs 1,10,000.

Because this is below the Rs 1.25 lakh threshold under Section 112A, no LTCG tax applies. Harvesting losses to offset these gains saves nothing.

You may still incur exit load and reset your holding period, leaving you worse off.

Scenario 3: Harvesting can backfire

Suppose you hold an equity fund for 11 months and 20 days and the investment is in loss. You harvest the loss now, booking an STCL.

But the newly purchased units begin a fresh holding period. If you need money within the next year and redeem those units at a gain, the gain will be taxed as STCG at 20 per cent, not LTCG at 12.5 per cent.

A 7.5 percentage-point difference in tax rate on future gains can easily exceed whatever tax you saved today.

How to execute a harvest

Option A: Redeem and reinvest

Redeem the units that are in loss. Then reinvest the proceeds in the same fund, or a similar one, on the same day if you want to maintain exposure.

Be mindful of NAV cut-off timing, which depends on transaction size. Check the applicable timing with your AMC or platform before transacting.

Option B: Switch within the AMC

Switch from the loss-making scheme to another scheme within the same AMC.

The switch-out leg is treated as a redemption and crystallises the loss. The switch-in creates fresh units with a new holding period.

In both cases, keep your capital gains statement and transaction records. The loss must be reported correctly in your ITR to be used in the current year or carried forward.

Common mistakes mutual fund investors make

“Switching is tax-free”
It is not. A switch is treated as a redemption for tax purposes. The switch-out leg can generate gains or losses.

“I’ll just do it in March”
Last-minute harvesting often leads to mistakes. You must check which units are short-term and which are long-term (FIFO applies), whether exit loads apply, and whether the NAV cut-off timing works for your transaction size.

“A long-term loss will offset short-term gains”
It will not. LTCL can offset only LTCG.

“I’ll bank the loss for the future”
Carry-forward is allowed only if you file your ITR before the due date. And it is useful only if you expect taxable gains in future years. If you rarely cross the Rs 1.25 lakh LTCG threshold, those losses may never be used.

“Debt funds work the same way”
They do not. Debt fund taxation has changed significantly in recent years and the rules differ materially from equity funds.

Frequently asked questions (FAQs)

Can mutual fund losses offset gains from stocks?

Yes. Capital losses and gains fall under the same head of income, ‘capital gains’. Mutual fund losses can therefore offset stock gains, subject to the STCL and LTCL rules described earlier.

Can a short-term loss reduce LTCG tax on equity funds?

Yes. STCL can be set off against both STCG and LTCG.

Is switching from a regular plan to a direct plan treated differently for tax?

No. It is treated as a redemption from the regular plan and a fresh purchase in the direct plan. Capital gains tax applies on the switch-out based on the holding period.

Does an STP trigger tax?

Yes. Each STP instalment is treated as a redemption from the source scheme and a purchase into the target scheme.

If I have no gains this year, should I still harvest losses?

Only if you expect taxable capital gains in future years and you file your ITR on time to carry forward the loss. Otherwise, it may not be worth the effort.

Has tax-loss harvesting effectively stopped after the rule changes?

No. The mechanics of set-off and carry-forward remain unchanged. What changed are the rates and thresholds, which affect when harvesting is worthwhile.

What is the biggest mistake investors make?

Ignoring the holding-period reset. Investors often save a small amount of tax today but accidentally convert future long-term gains (taxed at 12.5 per cent) into short-term gains (taxed at 20 per cent). The 7.5 percentage-point difference can easily wipe out the original savings.

The bottom line

Tax-loss harvesting in 2026 is a maths exercise, not a ritual.

Estimate your gross tax saving (12.5 per cent or 20 per cent of the usable loss). Then subtract your unavoidable costs, including exit load and the future tax cost of resetting the holding period.

If the savings are clearly larger, harvesting makes sense. If not, leave the portfolio alone.

The worst approach is doing it automatically every March because it feels prudent, without checking whether you have taxable gains to offset, whether your loss type matches your gain type, or whether you are about to convert future LTCG into STCG. Done thoughtlessly, harvesting can cost more than it saves.
