A capital gain is the profit you make when you sell a capital asset for more than you paid for it. Buy shares for Rs 1 lakh, sell them for Rs 1.5 lakh, and the Rs 50,000 difference is a capital gain that has to be reported and taxed.
The crucial point is that the gain is taxed only when you sell. A portfolio that has doubled on paper owes nothing. Nothing is due until you actually book the profit, which is why the timing of a sale is itself a tax decision.
Short-term or long-term
Everything turns on the holding period, and the threshold differs by asset.
| Asset | Long-term if held for |
|---|---|
| Listed equity shares and equity mutual funds | More than 12 months |
| Immovable property and unlisted shares | More than 24 months |
| Gold, debt funds and most other assets | More than 24 months |
Sell before the threshold and the gain is short-term. Cross it and it is long-term, and long-term treatment is almost always more favourable. This is a deliberate policy choice that rewards patient holding.
Rates on listed equity
For listed equity and equity mutual funds, the position following the 2024 changes has been:
- Long-term gains: taxed at 12.5%, and only on the amount above an annual exemption of Rs 1.25 lakh across all such gains in a financial year.
- Short-term gains: taxed at 20%.
So a Rs 3 lakh long-term equity gain in a year is taxed on Rs 1.75 lakh, producing a liability of roughly Rs 21,875.
These rates and the exemption threshold were revised in a recent Budget and can be revised again. Treat them as current-as-of figures and confirm the position for the relevant financial year before filing or before booking a large gain.
Debt funds, gold and property
Rules outside listed equity have changed materially in recent years, and old advice circulating online is frequently out of date.
Debt mutual funds bought after a specified date lost their long-term concession and indexation benefit, and gains are now generally added to income and taxed at slab rates regardless of holding period. Units bought before that cutoff may follow different rules.
Property carries its own regime, and the indexation position for property was changed in the 2024 Budget with an option offered for older acquisitions. This is an area where the arithmetic genuinely turns on your purchase date, so it is worth checking rather than assuming.
Given how much has moved here, verify current rules with the Income Tax Department or a qualified adviser before a large property or debt fund sale.
Setting off losses, which most people ignore
A capital loss is not wasted. It can be set off against gains, which directly reduces the tax you pay.
The rules follow a clear logic:
- Short-term losses can be set off against both short-term and long-term gains.
- Long-term losses can only be set off against long-term gains.
- Unused losses can be carried forward for eight assessment years, but only if you file your return by the due date. Miss the deadline and the carry-forward is lost.
This gives rise to tax loss harvesting: deliberately selling a loss-making holding before the financial year ends to book the loss against gains elsewhere, then reinvesting. Done carefully it is legitimate planning. Done carelessly it just generates transaction costs.
Practical ways to reduce the bill
- Use the annual exemption every year. If you have unrealised long-term equity gains, booking around Rs 1.25 lakh of gain annually and reinvesting resets your cost base at no tax cost. Unused exemption does not carry forward.
- Wait past the threshold where sensible. Selling equity at 11 months instead of 13 can nearly double the tax on that gain.
- Stagger large redemptions. Splitting a big sale across two financial years uses two years of exemption.
- Keep records. Purchase dates, amounts and reinvestments determine your cost of acquisition, and reconstructing them years later is unpleasant.
Note that ELSS redemptions are always long-term because of the three year lock-in, and that SIP instalments each carry their own purchase date and holding period, so a partial redemption applies units on a first-in-first-out basis.

Sections 54, 54F and 54EC provide relief on property gains where the proceeds are reinvested in a residential house or in specified bonds within defined timeframes. These have detailed conditions and strict deadlines, and they are worth understanding before, not after, a property sale.
Gains from a dividend are not capital gains at all. Dividends are taxed as income at your slab rate, which is a separate regime entirely.
