Indian investors must prioritise tax-loss harvesting amid new equity gain rules

With post-2024 tax rates confirmed for listed shares and mutual funds, Indian investors are urged to adopt strategic tax-loss harvesting to optimise net returns and preserve capital, making careful year-end review crucial.

Indian equity investors have a simple reminder from the latest tax rules: returns are only half the story. The other half is what survives after tax. For the current framework, listed equity shares, equity-oriented mutual funds and business trust units held for 12 months or less are taxed as short-term capital gains at 20%, while gains on holdings of more than 12 months are taxed at 12.5% after the annual exemption of ₹1,25,000. Official Income Tax Department guidance says those rates remain in force under the post-2024 regime, and later departmental material published in 2026 confirms the same treatment for the relevant equity categories.

That makes year-end tax planning more than a niche tactic. The basic idea behind tax-loss harvesting is straightforward: if a portfolio contains positions sitting on unrealised losses, an investor can sell them to create a capital loss and use that loss to reduce taxable gains realised elsewhere in the same year. In practice, that can help preserve more capital for reinvestment, especially in portfolios that have both winners and laggards. Market guides on the subject describe this as a way to keep equity exposure broadly intact while improving post-tax returns.

The set-off rules are where the strategy becomes more precise. A short-term capital loss can be used against both short-term and long-term capital gains, while a long-term capital loss can be set off only against long-term gains. Capital losses cannot be used against salary, business income or other non-capital heads. If losses remain unused, the Income Tax Act allows them to be carried forward for eight assessment years, but only if the return is filed on time under Section 139(3).

For investors closing the books before 31 March, the most useful habit is a full review of realised gains, unrealised losses and future tax exposure. If long-term gains for the year remain below the ₹1,25,000 exemption, some investors also use tax-gain harvesting to realise gains up to that limit and reset their cost base without creating a tax bill. The official guidance on capital gains reporting also makes clear that accurate disclosure in the relevant schedules matters, especially where grandfathering provisions or multiple brokerage accounts are involved.

The broader point is that tax efficiency should support, not distort, an investment plan. Selling a sound holding purely for a tax benefit may make little sense if brokerage costs, spreads or exit charges outweigh the saving. But used carefully, capital gains planning can improve net returns without adding market risk. In a regime where the rate structure for equity gains has been tightened and simplified, disciplined investors now have a stronger reason to track gains, losses and holding periods as closely as they track performance.
