Tax-Loss Harvesting Explained
What is it?
Tax-loss harvesting is the practice of deliberately selling an investment that's currently at a loss, in order to realise ("book") that loss for tax purposes, which can then be used to offset capital gains elsewhere in your portfolio — reducing your overall tax liability for the year. The investor can then reinvest the proceeds, often into a similar (but not identical, to avoid certain restrictions) fund to maintain their market exposure.
Why should you care?
Without deliberately harvesting a loss, an unrealised loss sitting in your portfolio provides no tax benefit — it's only when you actually sell and realise the loss that it becomes available to offset gains. Investors who never review their portfolio for this opportunity leave a legitimate, legal tax-saving tool unused.
Real-life example
An investor has one fund with a realised short-term gain of ₹60,000 this financial year, and another fund currently showing an unrealised loss of ₹20,000. By selling the losing fund before the financial year ends, the investor realises that ₹20,000 loss, which can be set off against the ₹60,000 gain — reducing the taxable gain to ₹40,000 and lowering the tax owed for the year, all while remaining a legitimate transaction if the investor then reinvests based on genuine portfolio considerations.
Common mistakes
- Never reviewing the portfolio for underperforming holdings near the financial year-end, missing the opportunity to offset gains elsewhere.
- Harvesting a loss purely for tax purposes without considering whether the fund still has a place in the portfolio or should be replaced with a better option.
- Forgetting that short-term and long-term losses can typically only be set off against gains of the same or compatible type under Indian tax rules — the offset isn't unlimited across every gain category.
Effect of tax-loss harvesting on taxable gains (illustrative)
| Without harvesting | With harvesting | |
|---|---|---|
| Realised gain (Fund A) | ₹60,000 | ₹60,000 |
| Realised loss (Fund B, harvested) | ₹0 (unrealised, no benefit) | ₹20,000 realised |
| Net taxable gain | ₹60,000 | ₹40,000 |
FAQ
Can I immediately buy back the same fund after harvesting a loss?
You can, since Indian tax rules (unlike some other countries) don't have a formal "wash sale" rule preventing immediate repurchase of the same fund — but it's worth checking current rules, as tax regulations can evolve, and considering whether reinvesting in a similar but different fund better diversifies your process.
Can losses be carried forward if I don't have enough gains to offset this year?
Yes — capital losses that aren't fully offset in the current financial year can typically be carried forward for a limited number of subsequent years to offset future gains, provided the loss is reported in a tax return filed on time.
Does tax-loss harvesting work for both equity and debt funds?
Yes, the general principle applies to both, though the specific rules for what type of loss can offset what type of gain (short-term vs. long-term, equity vs. debt) depend on current tax law — this is an area where consulting a tax professional for your specific situation is worthwhile.
Is tax-loss harvesting only useful near the financial year-end?
It can be done anytime during the year, but many investors review their portfolios specifically in the final quarter of the financial year (January-March) since that's when the tax-saving opportunity for that year is about to close.
