CAPITAL GAINS TAX BASICS FOR STOCKS AND MUTUAL FUNDS:
STCG AND LTCG MADE SIMPLE
Priya sold two things in the same week last March. A stock she'd bought eight months earlier, after a friend's tip, and a mutual fund SIP she'd held since 2019. Both trades made her roughly the same profit, around Rs. 90,000 each. She assumed the tax bill would be roughly the same too.
It wasn't. One gain was taxed at 20%. The other barely attracted any tax at all. The only real difference between the two was time, how long she'd held each investment before selling. That single variable, holding period, is the entire foundation of how capital gains tax works in India, and once you understand it, the rest falls into place quickly.
WHAT IS CAPITAL GAINS TAX, IN PLAIN TERMS?
When you sell a stock, mutual fund unit or any capital asset for more than you paid, the profit is called a capital gain, and the government taxes that gain, not your original investment. How much tax you pay depends on two things: what you sold, and how long you held it before selling. Hold something briefly, and it's taxed as a short-term capital gain, or STCG. Hold it longer, past a set threshold, and it becomes a long-term capital gain, or LTCG, usually taxed more gently to reward patience.
HOLDING PERIODS: THE LINE THAT DECIDES EVERYTHING
For listed equity shares and equity-oriented mutual funds, meaning funds that invest at least 65% in equities, the line is exactly 12 months. Sell within 12 months of buying, and it's short-term. Sell after 12 months, and it's long-term.
Debt mutual funds work differently, and this is where many investors get caught off guard. For debt fund units bought on or after April 1, 2023, there's no long-term category left at all. Every gain, regardless of how many years you held the units, is treated as short-term and taxed at your regular income tax slab rate. Units bought before that date, through what's called a grandfathering rule, may still qualify for the older long-term treatment with indexation if held beyond 36 months, so it's worth checking your purchase date carefully before assuming either way.
THE RATES, AS THEY STAND TODAY
Here's where things get concrete. For listed equity shares and equity mutual funds, short-term capital gains are taxed at a flat 20%, with no exemption on the amount. Long-term capital gains are taxed at 12.5%, but only on the portion exceeding Rs. 1.25 lakh in a financial year, so the first Rs. 1.25 lakh of long-term equity gains each year is effectively tax-free. These rates came from the July 2024 Budget, which raised STCG from 15% to 20% and LTCG from 10% to 12.5%, while also raising the exemption limit from Rs. 1 lakh to Rs. 1.25 lakh. The February 2026 Budget kept these rates unchanged for the current financial year, so they remain current as you read this.
Debt mutual funds, as covered above, skip this LTCG benefit entirely for units bought after April 2023. Whatever you gain gets added to your income and taxed at your slab rate, whether you held the units for six months or six years.
| ASSET | SHORT-TERM HOLDING PERIOD | STCG RATE | LONG-TERM HOLDING PERIOD | LTCG RATE |
| Listed equity shares | 12 months or less | 20% | More than 12 months | 12.5% above Rs. 1.25 lakh/year |
| Equity mutual funds | 12 months or less | 20% | More than 12 months | 12.5% above Rs. 1.25 lakh/year |
| Debt mutual funds (bought on or after April 1, 2023) | Any holding period | Taxed at your income slab rate | Not applicable | Not applicable |
A SIMPLE WORKED EXAMPLE
Back to Priya's two trades. Her stock, bought and sold within eight months, was a short-term gain of Rs. 90,000. At 20%, with no exemption available, she owed Rs. 18,000 in tax on that one trade alone.
Her mutual fund, held for over four years, was a long-term gain of Rs. 90,000. Since this fell entirely within the Rs. 1.25 lakh annual exemption for long-term equity gains, assuming she had no other long-term equity gains that year, she owed zero tax on it. Same profit, same rupee amount, a Rs. 18,000 differences in tax, purely because of how long each investment was held. That's the entire lesson in one example.
WHY RECORDS MATTER MORE THAN MOST INVESTORS REALISE
Capital gains tax isn't calculated once a year from memory. It's calculated trade by trade, and every number must trace back to a document. Three records matter most.
Your purchase date and price, for every single trade, decide which rate applies and what your actual gain is. A missing purchase date can accidentally push a long-term gain into the short-term bracket, costing you real money at tax time.
Your broker's contract notes and annual capital gains statement, usually available directly from your trading platform, give you a ready reconciliation of every buy and sell, which saves hours when filing returns.
Form 26AS and the Annual Information Statement, both available on the income tax portal, show what the tax department already knows about your trades through STT and broker reporting. If your own records don't match these, it's worth sorting out the mismatch before filing, not after.
One more detail worth keeping on file: if you held equity shares or mutual funds before January 31, 2018, a grandfathering rule lets you use the higher of your actual purchase price or the fair market value on that date as your cost of acquisition, which can meaningfully reduce your taxable gain on older holdings. Without that date and the corresponding price on record, you'd end up paying more tax than necessary.
Losses deserve the same discipline as gains. Short-term losses can be set off against both short-term and long-term gains, while long-term losses can only be set off against long-term gains. Unused losses can be carried forward for up to eight assessment years, but only if you've filed your return on time in the year the loss occurred. A record you don't keep is a benefit you simply don't get to use.
THE ONE HABIT THAT MAKES THIS EASY
None of this requires a finance degree. It requires one habit: noting the purchase date the moment you buy, not the moment you decide to sell. Hold a simple running log, stock or fund name, purchase date, purchase price, and the rest of your tax calculation becomes a lookup, not a reconstruction project done in a panic every March.
