This is one of the few genuinely free lunches in Indian tax law. It requires no risk, no new investment, and no change to your actual asset allocation. It just requires knowing the rule exists and doing a little paperwork once a year.
Long-term capital gains (units held over 12 months) on equity mutual funds and listed shares are taxed at 12.5% — but only on gains above ₹1.25 lakh in a financial year. The first ₹1.25 lakh of LTCG is exempt. This exemption is per person, per financial year, and it does not carry forward. Use it or lose it on 31st March.
| Step | What you do |
|---|---|
| 1 | Check your unrealised LTCG across equity mutual fund holdings held 12+ months |
| 2 | Redeem units worth up to ₹1.25 lakh of gain (not ₹1.25 lakh of investment value) |
| 3 | Gain booked is tax-free — no tax paid, no ITR complications beyond reporting |
| 4 | Reinvest the full redemption amount immediately, same fund or similar |
| 5 | Your new purchase cost (NAV) is reset higher — future tax on this slice is now lower |
Suppose you invested ₹5 lakh three years ago and it's now worth ₹7 lakh — a gain of ₹2 lakh. If you do nothing and eventually sell everything in year 8 with a total gain of ₹9 lakh, you pay 12.5% on ₹7.75 lakh (₹9L − ₹1.25L exemption that year) = roughly ₹96,875 in tax.
Instead, if you harvest ₹1.25 lakh of gain this year (tax-free), reinvest, and repeat next year on the new higher cost base, you keep shrinking the taxable gain that eventually crystallises. Done consistently over several years, this can meaningfully cut your lifetime tax bill on the same portfolio — with zero change in what you actually hold.
No. This ₹1.25 lakh exemption and the 12.5% LTCG rate apply specifically to equity-oriented mutual funds and listed shares. Debt mutual funds purchased after April 2023 are taxed at your slab rate regardless of holding period — there's no harvesting benefit there. If you're unsure which category your funds fall into, that's worth checking before assuming this strategy applies.
Anyone with equity mutual fund holdings older than a year and in genuine profit. It's especially valuable for large SIP portfolios accumulated over many years, where the gain component keeps growing. It's low-effort, low-risk, and purely administrative — the kind of thing an advisor should be checking on your behalf every February–March, alongside a broader asset allocation review.
Tax harvesting won't make you rich on its own — it's not a return-boosting strategy, it's a tax-efficiency strategy. But over a 15-20 year investing horizon, systematically using this exemption every year instead of ignoring it can save you a genuinely meaningful sum, compounded. The only cost is remembering to do it before the financial year closes.
