Annual LTCG Harvesting vs Buy-and-Hold Equity: The Rs 1.25 lakh Exemption Math, Family Arbitrage and Grandfathering

The Finance (No.2) Act 2024, effective 23 July 2024, redrew India's equity-tax landscape in one stroke. The long-term capital gains exemption under Section 112A of the Income Tax Act, 1961 rose from Rs 1 lakh to Rs 1.25 lakh per financial year, and the rate climbed from 10% to 12.5% on listed equity shares and equity-oriented mutual fund units where Securities Transaction Tax (STT) has been paid on transfer. That 25% rate hike, partly offset by a 25% larger exemption, has revived a strategy retail investors had largely ignored: annual tax-gain harvesting against the exemption envelope. For an investor with a Rs 10 lakh corpus growing at 12% for ten years, the choice between disciplined annual harvesting and pure buy-and-hold can swing the post-tax outcome by close to Rs 1.5 lakh.

The maths is not exotic. Each financial year, every Indian resident with listed equity or equity-oriented MF exposure can realise up to Rs 1.25 lakh of long-term capital gain tax-free under Section 112A. A buy-and-hold investor uses that exemption exactly once at exit. A harvester uses it ten times across a ten-year holding period, freezing Rs 12.5 lakh of cumulative gain into cost basis without paying a rupee of tax. The price of admission is operational discipline: each tranche must be held more than 12 months before it can be redeemed as long-term, and brokerage plus STT charges must be netted against the saving.

Side-by-Side Comparison

Consider two retail investors who each park Rs 10 lakh into a Nifty 50 index fund on 1 April 2026, expect 12% CAGR (broadly in line with the long-run Nifty 50 TRI as published in AMFI benchmark indices), and exit on 31 March 2036. Investor A harvests every March; Investor B redeems only at exit.

The figures assume total income below Rs 50 lakh, so surcharge is nil. The SIP calculator and Lumpsum calculator on Oquilia let you re-run the corpus build with your own monthly contribution and time horizon.

The harvesting flow is mechanical. On 20 March each year, the investor logs the holding statement, identifies units bought more than 12 months earlier with embedded LTCG, and redeems just enough to crystallise Rs 1.25 lakh of gain. The same amount is reinvested in the same scheme the next working day. NAV barely moves between redemption and re-investment, so the economic position is unchanged. Only the cost basis has been refreshed upward.

Tax Treatment

Section 112A of the Income Tax Act, 1961 governs LTCG on listed equity shares and equity-oriented mutual fund units where STT is paid on both purchase and transfer. The 12.5% rate applies to gains in excess of the Rs 1.25 lakh exemption from 23 July 2024, as enacted by the Finance (No.2) Act 2024. The surcharge cap for Section 112A income is 15%, regardless of overall income; the 4% Health and Education Cess applies on tax plus surcharge.

Short-term capital gain on the same asset class, with a holding period of 12 months or less, falls under Section 111A at 20%, raised from 15% on 23 July 2024.

Pre-2018 holdings continue to enjoy a grandfathering shield. For listed equity acquired before 1 February 2018, the cost of acquisition for computing capital gain is the higher of (a) the actual cost, and (b) the lower of the fair market value on 31 January 2018 and the full value of consideration on transfer. The Income Tax Department published share-wise highest quoted prices on BSE/NSE for that date; investors should download the official list rather than rely on broker statements that often miss splits and bonus adjustments.

Loss-side mechanics matter as much as gain-side. Under Section 70(3), a long-term capital loss can only be set off against another long-term capital gain, never against short-term gains or other income. Unutilised LTCL can be carried forward for eight assessment years under Section 74, but only if the return is filed within the due date under Section 139(1). For a harvester, this means losing positions should be booked in the same year as winners; the loss soaks up gain that would otherwise eat into the Rs 1.25 lakh exemption.

The Family-of-Four Arbitrage

The Rs 1.25 lakh exemption is per assessee, not per family. Two adults with separate PANs and demat accounts collect Rs 2.5 lakh of tax-free LTCG between them; a household with two earning adults and two adult children (over 18) reaches Rs 5 lakh annually. A Hindu Undivided Family with its own PAN can claim an additional Rs 1.25 lakh, taking the household envelope to Rs 6.25 lakh per FY.

The arbitrage is real but constrained by Section 64 of the Income Tax Act, which clubs income from gifted assets to the donor in two routes: gifts to spouse under Section 64(1)(iv) and gifts to minor children under Section 64(1A). Section 64 clubs income, such as dividends or interest, from the gifted asset. Subsequent capital gains from sale of the gifted shares, by judicial precedent and CBDT practice, are taxed in the donee's hands once the shares have been transferred to and held in their own demat. Investors should still document the gift via a registered or notarised deed and ensure the donee has independent broker KYC.

Children above 18 are fully independent assessees. A Rs 2 lakh equity portfolio gifted to a 19-year-old college student can be harvested annually under their own PAN; if their other income stays below the basic exemption limit and LTCG stays within Rs 1.25 lakh, the entire realisation is tax-free.

Who Should Pick Which

The harvesting strategy is not free. Each transaction costs STT (0.001% on equity MF redemption, 0.025% on direct equity sale per current CBDT rates), brokerage where applicable, and the operational burden of tracking grandfathered cost bases, FIFO lot identification, and re-investment timing. For very small corpora, the absolute saving may not justify the work.

Profile A — SIP investor, Rs 5,000 monthly contribution, 15-year horizon. Embedded gains stay well below Rs 1.25 lakh for the first six to seven years, so harvesting offers little. Better to buy-and-hold and switch on annual harvesting only when annual notional gain crosses Rs 1.5 lakh. The SIP calculator output helps estimate the inflection year.

Profile B — Lump-sum investor with Rs 25 lakh in equity MFs. Annual notional gains at 12% are around Rs 3 lakh from year one. Harvesting saves Rs 16,000 to Rs 20,000 per year after costs and compounds materially over a decade. Single demat, single PAN, but worth the effort.

Profile C — Household with two earning adults plus adult children. Distributing fresh investments across PANs, using the ELSS calculator to time tax-saving and harvesting jointly, can shelter Rs 5 lakh of LTCG per FY. Cost: maintaining clean money trails and separate filings.

Profile D — HNI with corpus over Rs 1 crore and total income in the 30% slab. Effective Section 112A tax with maximum 15% surcharge and 4% cess is 12.5% x 1.15 x 1.04 = 14.95%. Harvesting still helps, but the bigger gain is from pairing harvested losses against unharvested winners, since LTCL is fungible across schemes within the long-term bucket.

Direct equity investors should also note that grandfathered shares carry an additional informational asymmetry. A pre-2018 holding with a tiny actual cost but a high 31 January 2018 FMV can be harvested aggressively against the Rs 1.25 lakh envelope before exit; the same logic applies to ESOP shares vested before that date. The PPF calculator and the NPS calculator help compare the harvested-equity route with debt-side compounding for the same tenure.

Investors weighing equity LTCG against the older debt-fund regime should read our analysis on the debt mutual fund tax shift post-April 2023, which walks through why post-April 2023 debt holdings no longer enjoy indexation. For credit-spread choices within fixed income, PSU Bond Fund vs Corporate Bond Fund explores the AAA-versus-AA trade-off. And for retirement-bucket equity, the comparison in NPS Tier 1 vs Tier 2 is essential reading, since Tier 1 corpus locks until 60 while Tier 2 is fully liquid. Long-run benchmark return data is published periodically by AMFI India.

Practical Calendar

• April to November: Review tranche-wise unrealised gains. Identify positions that crossed 12 months and have embedded LTCG.
• December: Run the harvesting simulation. Pair losses with winners if both exist.
• Mid-February: Execute redemptions. Reinvest the same day or next working day to minimise market-timing risk.
• 31 March: Confirm the realised LTCG figure with broker capital gains statement (most brokers issue it before 15 April).
• 31 July: File ITR-2 with Schedule CG, reporting harvested gains and re-investment.

FAQ

Is the Rs 1.25 lakh exemption available in both old and new tax regimes?

Yes. The Section 112A exemption of Rs 1.25 lakh per FY applies regardless of whether the taxpayer opts for the old regime or the new regime under Section 115BAC. It is a feature of the capital gains chapter (Chapter IV-E), not of slab taxation. Note that Section 80CCD(1B), Section 80C and most Chapter VI-A deductions are unavailable in the new regime, but Section 112A is unaffected.

Can short-term capital loss be set off against long-term capital gain?

Yes. Section 70(3) allows short-term capital loss to be set off against either short-term or long-term capital gain. The reverse is not true: long-term capital loss can be set off only against long-term capital gain. This asymmetry favours harvesting short-term losses early in the year if you also have long-term gains to shelter.

Does the 12.5% LTCG rate apply to all unlisted shares as well?

From 23 July 2024, the LTCG rate on unlisted shares, real estate, debt MFs and gold is also 12.5% under Section 112, but without the Rs 1.25 lakh exemption (which is exclusive to Section 112A listed equity and equity MFs). Indexation has been removed for transfers on or after 23 July 2024, with a residential-property carve-out allowing taxpayers to compare and pick the lower of 12.5% without indexation and 20% with indexation, for properties acquired before 23 July 2024.

What about surcharge on LTCG?

Surcharge for Section 112A income is capped at 15%, regardless of overall income. In the new regime under Section 115BAC, the overall surcharge cap is 25%, but Section 112A LTCG retains its own 15% cap. The 4% Health and Education Cess applies on tax plus surcharge.

Will harvesting trigger STT and dent returns?

Yes, but minimally for equity MFs. STT on equity MF redemption is 0.001%, which is Rs 12.50 on a Rs 12.5 lakh redemption. Direct equity sale STT is 0.025% on the sell side. Total round-trip cost for redeem-and-rebuy in equity MFs is typically under 0.02%, well below the tax saving harvested.

Does harvesting reset the 12-month holding period for the next harvest?

Yes. The re-bought units start a fresh acquisition date. To harvest those units' gains tax-free again, you must hold them more than 12 months. This is why annual harvesting needs at least 12 months between cycles. For an SIP investor, FIFO lot identification under Rule 2 of the Income-tax Rules applies; the earliest-acquired units are deemed redeemed first.

How do I avoid clubbing when gifting equity to my spouse?

Clubbing under Section 64(1)(iv) applies to income from assets gifted to a spouse without adequate consideration. The cleanest approach is to gift via a registered or notarised gift deed and recognise that subsequent capital gains from sale of the gifted asset are taxed in the donee spouse's hands, while dividends from the gifted shares would be clubbed to the donor. Alternatively, gifts to adult children attract no clubbing. Always check with a Chartered Accountant before structuring large family gifts.
