Tax-Loss Harvesting for Indian Investors

What tax-loss harvesting actually means

At a high level, you sell investments that are sitting at a loss so those realised losses can potentially offset realised gains elsewhere in the portfolio. The goal is not to sell good assets indiscriminately. The goal is to make tax-aware decisions while still keeping your long-term asset allocation intact.

In practice, this requires looking at each position lot carefully, understanding how gains are computed, and checking whether the expected tax benefit is worth the trade-off.

STCG vs LTCG: the two rates that drive every decision

In India, how long you have held a listed equity share or an equity mutual fund decides which tax bucket a gain or loss falls into. For listed equity and equity-oriented mutual funds, a holding period of 12 months or less is short term, and anything held for more than 12 months is long term. (US stocks and debt-oriented funds follow different holding periods and rates, which is one more reason to review each asset class on its own terms.)

Under the rules that apply to sales on or after 23 July 2024, short-term capital gains (STCG) on Indian equity and equity funds are taxed at 20%, while long-term capital gains (LTCG) are taxed at a flat 12.5% with no indexation. Crucially, LTCG on listed equity and equity mutual funds is exempt up to ₹1.25 lakh per financial year; only the gain above that threshold is taxed. That single exemption changes the maths of harvesting more than almost anything else, because realising a small long-term loss to shelter a gain you could have taken tax-free is simply wasted effort.

How losses can be set off and carried forward

Harvesting only helps if the loss you realise can actually be used. Indian capital-gains set-off rules are specific, and getting them wrong is the most common reason a harvest delivers no benefit:

• A short-term capital loss can be set off against both short-term and long-term capital gains.
• A long-term capital loss can be set off only against long-term capital gains — never against short-term gains.
• Capital losses cannot be set off against salary, business, or other heads of income — they stay within the capital-gains head.
• Unused capital losses can generally be carried forward for up to 8 financial years, but only if you file your income tax return on or before the due date.

Because short-term losses are the more flexible of the two, they are often the higher-value thing to harvest when you have a mix of realised gains. The practical takeaway: match the type of loss you realise to the type of gain you are trying to offset.

A simple worked example

Suppose that during the financial year you have already booked ₹2,00,000 of short-term capital gains on an equity position you sold to fund a purchase. At the 20% short-term rate, that gain alone would attract roughly ₹40,000 in tax.

Now suppose you also hold a different stock that is down ₹1,50,000 from your cost, and it no longer fits your allocation. If you realise that short-term loss, it can be set off against the ₹2,00,000 short-term gain, leaving only ₹50,000 taxable — about ₹10,000 of tax instead of ₹40,000. The harvest saved roughly ₹30,000, and you exited a position you wanted out of anyway.

The example is deliberately clean. Real portfolios rarely are: gains and losses sit in different buckets, lots were bought on different dates, and the order in which units are treated as sold changes the realised figure. That is where the mechanics below matter.

Why FIFO matters for Indian investors

Capital gains calculations depend on the order in which units or shares are treated as sold. For listed securities and mutual funds, the first-in-first-out (FIFO) convention generally applies: the earliest lots you bought are treated as the first ones sold. For many investors, FIFO can change the realised gain or loss significantly compared with a simple average-price mental model.

This matters for harvesting in two ways. First, the lot that gets sold determines the holding period — and therefore whether the result is a short-term or long-term loss, which decides how it can be set off. Second, a position that looks like a loss on an average-cost basis may include older lots sitting at a gain, so the realised number can be smaller, or even positive, once the transactions are walked lot by lot. The harvesting opportunity you think you have may differ from the one that is actually available.

When harvesting can make sense

Common mistakes to avoid

• Selling purely for tax reasons without checking whether the investment thesis still holds.
• Ignoring holding period differences and assuming all gains are taxed the same way.
• Using average acquisition cost in planning when the actual tax treatment depends on lots.
• Reviewing one account in isolation instead of the full portfolio.
• Waiting until the last minute and making rushed decisions.

Velthian is built to give you a portfolio-wide view of holdings, realised gains, and tax-aware opportunities across asset classes. Instead of checking one broker statement at a time, you can see where potential harvesting opportunities sit, how they affect your tax picture, and whether they fit your wider allocation decisions.
