The ₹15,625 Free Lunch
In the world of investing, there is no such thing as a free lunch. Except for one.
The Indian Income Tax Act allows you to realize up to ₹1.25 Lakhs in Long-Term Capital Gains (LTCG) from equity investments completely tax-free every single financial year.
The catch? This limit does not carry forward. If you don't book ₹1.25 Lakhs of profit by March 31st, it expires forever. Over a 20-year investing journey, failing to harvest this limit means you will unnecessarily pay over ₹3 Lakhs in taxes (12.5% on the gains) when you finally liquidate your corpus.
What is Tax Harvesting?
Tax Harvesting is the practice of selling mutual fund units that have accumulated long-term profits (held for >1 year) up to the ₹1.25 Lakh tax-free limit, and immediately repurchasing them. This permanently resets your purchase price (booking the profit tax-free) while keeping your money invested in the market.
The Math Behind the Magic
Let's assume you invested ₹10 Lakhs in a Nifty 50 Index Fund. After 14 months, the value has grown to ₹11.20 Lakhs. You have an unrealized Long-Term Capital Gain of ₹1.20 Lakhs.
| Metric | Scenario A: Do Nothing | Scenario B: Tax Harvest Today |
|---|---|---|
| Current Action | Hold | Sell entire ₹11.20L and Re-buy |
| Booked Profit Today | ₹0 | ₹1.20 Lakhs |
| Tax Paid Today | ₹0 | ₹0 (Below ₹1.25L limit) |
| New Purchase Price | ₹10 Lakhs (Original) | ₹11.20 Lakhs (Reset higher) |
Fast Forward 10 Years: The fund grows to ₹50 Lakhs and you sell to fund your retirement.
- Scenario A Tax: You calculate profit from the original ₹10L. Gain = ₹40 Lakhs. Taxable = ₹38.75L. Tax Bill = ₹4,84,375
- Scenario B Tax: You calculate profit from the new ₹11.20L. Gain = ₹38.8 Lakhs. Taxable = ₹37.55L. Tax Bill = ₹4,69,375
By simply pressing "sell" and "buy" on your broker app on a Tuesday morning, you saved ₹15,000 in future taxes. If you repeat this every single year, constantly resetting your purchase price upward, you save lakhs.

1. The 2-Day Settlement Gap Risk
When you sell a mutual fund, the money hits your bank account in T+2 days. During those two days, you are out of the market. If the market shoots up 3%, you lose out on the gains, destroying the tax benefit.
- The Hack: If you have spare cash in your bank account, buy the new units first. Then, on the exact same day, sell the old units. Both transactions execute at the same day's NAV, completely eliminating the settlement gap risk.
2. Avoid STCG (Short-Term Capital Gains)
Only sell units that you have held for more than 365 days. Selling units held for 364 days triggers a massive 20% Short-Term Capital Gains tax, completely ruining the strategy.
3. Watch the Exit Loads
Before selling, ensure the units you are selling do not attract an Exit Load (usually 1% if sold before 365 days). Since LTCG applies after 1 year, the exit load has almost always expired anyway, but always check your specific fund's factsheet.

Start Your Free PlanFAQs
1. Does tax harvesting work for Debt Mutual Funds?
No. Following the recent tax changes, debt mutual funds are taxed at your income slab rate regardless of holding period (no indexation, no LTCG distinction). The ₹1.25 Lakh tax-free limit applies only to Equity Mutual Funds and direct Indian stocks.
2. Can I harvest losses instead of gains?
Yes! Tax-Loss Harvesting is just as important. If a stock or mutual fund is down, you can sell it to book a "Short Term Capital Loss." You can then use this booked loss to offset any other Short Term Capital Gains you make in the same year, legally lowering your tax bill.
3. What is the wash sale rule, and does it apply in India?
In the US, the "wash sale" rule prevents you from claiming a tax benefit if you sell an asset and buy the exact same asset within 30 days. India does not have a wash sale rule. You can sell a Nifty 50 fund at 10:00 AM and buy it back at 10:01 AM and legally claim the tax harvest.
4. Do I need to buy a different mutual fund when I reinvest?
No. Because India lacks a wash sale rule, you can buy the exact same fund you just sold. However, many investors use harvesting as a convenient time to rebalance their portfolio or shift from a poorly performing fund to a better index fund without triggering taxes.
5. How does plannF handle tax harvesting in simulations?
plannF's tax engine is hyper-realistic. It tracks individual "tax lots" for every SIP you make. During a 40-year simulation, the engine automatically harvests exactly ₹1.25 Lakhs of LTCG every single March, resetting the cost basis, and passing the compound savings directly to your net worth.
