What is Short Term Capital Gains (STCG) tax?

What exactly happens when you sell a stock or a mutual fund within a year of buying it? That is the corner of capital gains tax in India known as short term capital gains tax, or STCG. Most investors hear the term, nod, and only pay attention when the tax bill arrives. By then it is too late to plan. Understanding STCG before you sell is the difference between keeping your profit and quietly handing a chunk of it back to the government.

This is the plain-language version. No jargon, no padding. Just what STCG is, how it works in India, and what to watch.

What short term capital gains tax actually is

STCG is the tax you pay on profit made by selling a capital asset within a short holding period defined by the Income Tax Act. The holding period that decides whether a gain is short or long term differs by asset type.

• Listed equity shares and equity-oriented mutual funds: holding period is 12 months.
• Unlisted shares and immovable property: holding period is 24 months.
• Debt mutual funds, gold, and most other capital assets: holding period is 24 months from April 2024 onwards, with several special cases under recent budgets.

If you sell before the threshold, the gain is short term and is taxed under the STCG rules.

How STCG is calculated

The calculation itself is simple.

• Sale price minus the cost of acquisition equals the gain.
• Allowable expenses related to the sale, such as brokerage and STT for some assets, are subtracted as permitted.
• The result is your short term capital gain.

Each transaction is computed separately. You do not net long term gains against short term gains in the same way you might assume. Set-off rules are specific and worth checking before filing.

STCG rates on common assets in India

The rates depend on the asset type.

• Listed equity shares and equity mutual funds (where STT is paid): STCG is taxed at 20 percent under section 111A, effective from July 2024.
• Other short term capital gains: taxed at your applicable income tax slab rate.
• Virtual digital assets like crypto: a flat 30 percent applies under section 115BBH, separate from STCG rules.

Always confirm the current rate at filing time. Budget changes can alter rates from year to year.

How STCG fits into your total tax

Short term capital gains on listed shares under section 111A are taxed at the flat rate of 20 percent. They are not added to your slab income, but they do count toward your overall taxable income for purposes such as surcharge calculation.

Other short term gains, like on a property held under 24 months or on unlisted shares, are added to your slab income and taxed accordingly. That is the key fork most investors miss.

Real example to make this concrete

An investor buys 1,000 shares of a listed company at 250 rupees each. Total cost: 2,50,000 rupees. She sells them six months later at 320 rupees each. Total sale: 3,20,000 rupees. The short term gain is 70,000 rupees. STCG at 20 percent under section 111A is 14,000 rupees. Add applicable surcharge and cess. Her net post-tax profit is around 56,000 rupees.

The same investor, holding for 12 months and one day instead of 6 months, would have paid long term capital gains tax at 12.5 percent above the basic exemption of 1.25 lakh rupees per year. The holding period alone changes her tax bill meaningfully.

Set-off and carry forward rules you should know

Losses interact with gains in specific ways.

• Short term capital losses can be set off against both short term and long term capital gains in the same year.
• Long term capital losses can be set off only against long term capital gains.
• Unabsorbed short term capital losses can be carried forward for 8 years, but only against capital gains.
• To carry forward losses, you must file your tax return on time.

A small habit of harvesting losses before March 31 can shave off real tax. Just stay within the spirit of the rules and document every trade.

When STCG applies and when it does not

Not every sale triggers STCG.

• Gifts to relatives are not taxable as capital gains for the donor, but the asset's history transfers to the recipient.
• Inherited assets do not trigger capital gains at the time of inheritance. The clock and cost basis pass to the heir.
• Some transfers under specific sections, such as conversion of physical shares to demat, are not regarded as transfers.

If a transaction sits in a grey area, check section 47 of the Income Tax Act, or take a quick view from a chartered accountant.

Reporting STCG correctly in your tax return

Short term capital gains are reported in the capital gains schedule of your ITR. For most retail investors with equity transactions, that means ITR-2. Salaried investors may also use ITR-1 only if they have no capital gains.

• Use the broker's capital gains statement to populate the schedule.
• Cross-check against the Annual Information Statement and Form 26AS.
• Report each scrip separately if required by the schema for that year.

You can read the latest ITR instructions on the income tax portal at incometax.gov.in. The schemas evolve, so always download the current year's version.

Common mistakes investors make with STCG

• Selling listed equity right before the 12-month mark and paying 20 percent instead of waiting a few extra days.
• Forgetting that STCG on debt funds bought after April 2024 is taxed at slab rates with the long-term advantage removed.
• Not setting off short term capital losses against gains in the same year.
• Missing the deadline to file the return, which kills the right to carry forward losses.
• Confusing the holding period clock for shares bought via SIP. Each SIP installment has its own holding period.

Frequently asked questions on STCG

Is the 1.25 lakh exemption available for STCG?

Can I save STCG with section 54 or 54F?

No. Section 54 and 54F exemptions apply only to long term capital gains. STCG cannot be deferred or exempted through these reinvestment routes.

Does STCG apply on intraday equity trading?

No. Intraday trading is treated as speculative business income, not as capital gains. It is taxed at slab rates and reported separately.

Understanding short term capital gains tax is one of the simplest ways to keep more of your investment profit. Plan the holding period, harvest losses on time, and file the return correctly. The rest of capital gains tax in India suddenly feels manageable.
