Tax-Loss and Gain Harvesting in Equity Portfolios: The FY 2026-27 Playbook

Two Different Ideas With Similar Names

Indian investors use the phrase "tax harvesting" loosely for two distinct manoeuvres, and confusing them costs money.

Tax-loss harvesting means selling a holding that is currently below your purchase price, crystallising the loss, and using that loss to offset taxable capital gains elsewhere in the same financial year — or carrying it forward for up to eight years.

Gain harvesting is the opposite: deliberately selling a *profitable* long-term equity holding to book a gain of up to ₹1.25 lakh in a year, paying zero tax on it because of the annual exemption, and repurchasing to reset your cost base upward.

Both are entirely legal, both are mechanical, and both are consistently under-used. With the LTCG rate on listed equity at 12.5% and short-term gains at 20% for transfers on or after 23 July 2024, the rupee value of getting this right has gone up materially.

The Set-Off Rules You Must Know

The hierarchy of set-off under the capital gains provisions — now carried into the Income-tax Act, 2025, effective 1 April 2026, with the same substance as the erstwhile Sections 70–74 — works like this:

Two implications follow immediately.

First, STCL is the more valuable loss because it is flexible. If you have both a short-term loser and a long-term loser and can only book one, the short-term one usually does more work.

Second, capital losses cannot reduce your salary or FD interest. A salaried investor with no gains at all in FY 2026-27 still benefits from booking losses, but only because of carry-forward — the benefit is deferred, not immediate.

The Carry-Forward Condition Everyone Forgets

To carry a capital loss forward, you must file your return of income by the due date specified for the original return. For most individual taxpayers that is 31 July following the financial year (31 October where a tax audit applies). File a belated return and the loss carry-forward is lost permanently — even though the loss genuinely occurred.

You must also actually report the loss in the capital gains schedule of the ITR. A loss omitted from the schedule cannot be resurrected in a later year, and a revised return only helps if the original was timely.

One more practical point: losses carried forward from earlier years get set off before the current year's losses in most computations, and unabsorbed losses lapse after the eighth assessment year. Keep a simple running register of loss year, amount and expiry.

Gain Harvesting: Using the ₹1.25 Lakh Exemption Every Single Year

The exemption of ₹1.25 lakh per financial year on long-term gains from listed equity shares and equity-oriented mutual funds is a *use-it-or-lose-it* allowance. It does not accumulate.

Consider an investor holding ₹12 lakh of an equity index fund bought three years ago at ₹8 lakh — an unrealised gain of ₹4 lakh.

• •Option A — do nothing. Sell everything in year five when the gain has grown to ₹7 lakh. Taxable: ₹7,00,000 − ₹1,25,000 = ₹5,75,000 at 12.5% = ₹71,875.
• •Option B — harvest annually. Each year, redeem units carrying roughly ₹1.25 lakh of gain, pay nil tax, and reinvest the proceeds the next working day. Over four years you shelter ₹5 lakh of gains at zero tax, leaving only ₹2 lakh of residual gain to be taxed later: (₹2,00,000 − ₹1,25,000) × 12.5% = ₹9,375.

The saving is real, but it is not free. Watch for:

• •Exit load on the repurchased units, which restarts the load clock (usually 1% if redeemed within a year on equity schemes).
• •Holding-period reset. The new units start a fresh 12-month clock. Harvest only what you are confident you will not need to sell within the next year.
• •Out-of-market risk. You are typically out for one settlement cycle (T+1 for listed shares; mutual fund redemption proceeds reach the bank in 1–3 working days). A sharp up-move in that window can cost more than the tax saved. Some investors avoid this by harvesting across two schemes with similar mandates so they are never fully out.
• •STT and brokerage on both legs for direct shares.

The Two Traps: Bonus Stripping and Dividend Stripping

The Income-tax Act specifically neutralises two artificial loss-creation strategies, and the provisions apply to securities and mutual fund units alike after the widening introduced in 2022.

Dividend stripping: If you buy units or securities within 3 months *before* a record date, receive the dividend/IDCW, and sell within 3 months *after* (9 months for units), the loss to the extent of the dividend received is disallowed.

Bonus stripping: If you buy units/securities within 3 months before a bonus record date and sell the original holding within 9 months after, the loss is ignored and instead added to the cost of the bonus units.

Beyond these codified rules, India does not have an explicit US-style "wash sale" prohibition on repurchasing the same security. However, purely circular same-day transactions designed only to create a loss with no change in economic position can attract scrutiny — including under GAAR for large, deliberately structured arrangements. Keeping a genuine gap between sale and repurchase, and avoiding matched cross-trades, is the sensible discipline.

Where Losses Come From in a 2026 Portfolio

Loss harvesting is not only about beaten-down stocks. Common sources include:

• •Sectoral and thematic funds bought near a peak.
• •International funds where currency and market moves have diverged from Indian equity returns.
• •Debt-oriented funds bought after 31 March 2023, where any gain or loss is short term and taxed at slab rate — meaning a loss here is a slab-rate-value STCL that can offset even your equity LTCG. This is one of the highest-value harvests available.
• •Gold and other funds now taxed at 12.5% after 24 months.
• •Delisted or suspended shares, where a loss can be claimed only on an actual transfer; simple erosion in value is not a transfer.

A Month-by-Month Execution Calendar for FY 2026-27

A word on advance tax: capital gains are notoriously hard to forecast, which is why the law allows them to be reckoned in the instalment falling due *after* the gain arises. But a gain booked in early March must be covered by 15 March, or interest under Section 234C applies on the shortfall.

Who Should Not Bother

Harvesting is a tool, not a virtue. Skip it if:

• •Your total equity gains for the year are already below ₹1.25 lakh — there is nothing to shelter.
• •The holding is a core long-term compounder and the exit load plus out-of-market risk exceeds the tax saved.
• •You are close to a 24-month or 12-month boundary; waiting a few weeks converts a 20% STCG into a 12.5% LTCG with exemption headroom.
• •Your transaction costs and the time cost of paperwork exceed a few thousand rupees of tax. Chasing ₹800 of savings across nine trades is not tax planning.

E-Square Tip: Run one consolidated "harvest sheet" every January, not every March. List each holding with purchase date, cost, current value and the exact date it crosses the 12- or 24-month long-term threshold. Nine times out of ten, the largest saving does not come from a clever loss trade — it comes from simply *delaying* a planned sale by three or four weeks so the gain shifts from the 20% short-term bucket into the 12.5% long-term bucket with a ₹1.25 lakh exemption sitting on top of it.
