Most mutual fund investors in India pay more tax than they need to — simply because they are not aware of a perfectly legal strategy called tax harvesting. With the LTCG exemption of Rs 1.25 lakh per year and the ability to strategically book losses, disciplined investors can save tens of thousands of rupees in tax every year. This guide explains exactly how to do it.
What Is LTCG Harvesting?
Under current tax rules, long-term capital gains (LTCG) from equity mutual funds up to Rs 1.25 lakh per year are completely tax-free. Gains above this threshold are taxed at 12.5 percent. LTCG harvesting is the strategy of deliberately booking profits up to the Rs 1.25 lakh exemption limit each financial year and immediately reinvesting the proceeds. This resets your purchase cost to a higher level, reducing future taxable gains.
If you do not harvest your Rs 1.25 lakh LTCG exemption each year, you lose it forever. It does not carry forward. Over 10 years, this wasted exemption can cost you Rs 1.5 to 2 lakh in additional tax.
Step-by-Step LTCG Harvesting Process
- Step 1: In January-February each year, check your equity mutual fund portfolio for unrealized long-term gains (units held for more than 12 months)
- Step 2: Calculate how many units you need to redeem to book gains of approximately Rs 1.25 lakh
- Step 3: Redeem those units — the LTCG up to Rs 1.25 lakh will be completely tax-free
- Step 4: Wait for 1-2 business days for the redemption to settle
- Step 5: Reinvest the entire redeemed amount back into the same fund or a similar fund
- Step 6: Your new purchase cost is now higher, reducing future taxable gains
LTCG Harvesting: A Worked Example
Suppose you invested Rs 10 lakh in an equity fund 3 years ago. The current value is Rs 16 lakh, giving you Rs 6 lakh in unrealized gains. In Year 1, you redeem enough units to book Rs 1.25 lakh in gains (tax-free) and reinvest. Your new cost basis becomes Rs 11.25 lakh. In Year 2, you repeat the process. Over 4 years, you can harvest the entire Rs 6 lakh gain tax-free, saving Rs 75,000 in tax (6 lakh x 12.5 percent).
| Year | Action | Gains Harvested | Tax Saved | New Cost Basis |
|---|---|---|---|---|
| Year 1 | Redeem and reinvest | Rs 1.25 Lakh | Rs 15,625 | Rs 11.25 Lakh |
| Year 2 | Redeem and reinvest | Rs 1.25 Lakh | Rs 15,625 | Rs 12.50 Lakh |
| Year 3 | Redeem and reinvest | Rs 1.25 Lakh | Rs 15,625 | Rs 13.75 Lakh |
| Year 4 | Redeem and reinvest | Rs 1.25 Lakh | Rs 15,625 | Rs 15.00 Lakh |
| Total | - | Rs 5.00 Lakh | Rs 62,500 | - |
Tax-Loss Harvesting: The Other Side of the Coin
Tax-loss harvesting works in the opposite direction. When some of your holdings are in loss, you redeem them to book a capital loss. This loss can be set off against any capital gains you have earned, reducing your tax liability. Short-term capital losses can be set off against both short-term and long-term gains. Long-term capital losses can be set off only against long-term gains. Unabsorbed losses can be carried forward for 8 years.
Common Mistakes to Avoid
- Do not trigger STCG by selling units held for less than 12 months while trying to harvest LTCG
- Do not reinvest into a completely different fund type — maintain your asset allocation
- Account for exit load — choose funds with zero or near-zero exit load after 12 months
- Do not forget stamp duty (0.005 percent) and STT on the redemption, though these are negligible
- Keep records of all transactions for tax filing — your CA will need redemption and reinvestment details
- Do not wait until March to harvest — market volatility could reduce your gains by then
The best time for tax harvesting is January or February each year. You have clarity on your full-year gains and enough time to execute before March 31. Set a calendar reminder and make it an annual ritual.
Earning returns on your investments is important, but keeping those returns by minimizing tax is equally important. Tax harvesting is not tax avoidance — it is smart tax planning that the law explicitly allows.
