Introduction
Every rupee of profit from selling shares is taxable in India, but the rate you pay depends entirely on one factor: how long you held the shares before selling. Short-Term Capital Gains Tax on Shares applies when you sell listed equity shares within 12 months of purchase, and it follows a distinct flat-rate structure that’s separate from your regular income tax slab. This article breaks down the applicable tax rate, calculation method, and the practical considerations every investor should know before selling shares held for a short duration.
When Does Short-Term Capital Gains Tax Apply to Shares?
Short-term capital gains tax applies whenever you sell listed equity shares on a recognized stock exchange within 12 months of buying them, provided Securities Transaction Tax (STT) has been paid on the transaction. If you hold the shares for more than 12 months instead, the gain is reclassified as long-term and taxed under a completely different, generally more favorable regime.
The 12-month threshold is a hard cutoff. Selling even a day before completing 12 months means the entire gain is treated as short-term, with no partial or proportional benefit.
The Applicable Tax Rate
Under Section 111A of the Income Tax Act, short-term capital gains on listed equity shares are taxed at a flat rate of 20%. This rate applies uniformly to every taxpayer, irrespective of their income tax slab, and was increased from the earlier 15% to 20% through the Finance Act 2024, effective from July 23, 2024.
This flat-rate treatment is often misunderstood. Many investors assume STCG on shares gets added to their total income and taxed progressively like salary or business income, but that isn’t how it works. Whether your total annual income places you in the 5% bracket or the 30% bracket, your STCG on shares is taxed at the same flat 20%, separately from your other income.
There is also no exemption threshold for STCG on shares. Every rupee of gain is taxable, unlike LTCG, where gains up to ₹1.25 lakh per year are exempt.
Calculating Short-Term Capital Gains Tax on Shares
The calculation follows a simple sequence:
- Step 1: Determine the sale value: The total proceeds received from selling the shares.
- Step 2: Deduct transfer-related expenses: This includes brokerage fees and other direct costs of the sale.
- Step 3: Subtract the cost of acquisition: The original purchase price of the shares, including any brokerage paid at the time of buying.
- Step 4: Compute the gain
STCG = Sale Value − Cost of Acquisition − Expenses on Transfer - Step 5: Apply the 20% flat rate
Example:
You purchase shares worth ₹3,00,000 and sell them five months later for ₹3,75,000, incurring ₹3,000 in total brokerage. Your STCG comes to ₹72,000. Tax payable is 20% of ₹72,000, which is ₹14,400, plus applicable cess, regardless of what tax bracket you’re otherwise in.
Cess and Surcharge on STCG
On top of the 20% base rate, a 4% Health and Education Cess applies to the calculated tax amount. Depending on your total income, an additional surcharge may also apply, further increasing the effective tax outgo for high-income taxpayers.
Setting Off Losses Against STCG on Shares
If you’ve booked losses on other short-term share sales during the year, these can be set off against your short-term capital gains, reducing your net taxable amount. Short-term losses can also be set off against long-term capital gains in the same year. Any losses that remain unadjusted can be carried forward for up to eight assessment years, provided you file your income tax return within the due date.
This makes tax-loss harvesting, selling underperforming shares deliberately to book a loss, a genuinely useful year-end strategy for investors with a mix of winning and losing positions.
Conclusion
Short-Term Capital Gains Tax on Shares operates under a flat 20% rate that applies to everyone equally, with no exemption to soften the impact. This makes it considerably more expensive than the long-term alternative, and it’s a key reason why holding period is one of the first things serious investors factor into their selling decisions. Understanding this rate, tracking your holding periods accurately, and using loss set-offs where available can help you manage your tax liability more effectively. For anyone trading actively or managing a mixed portfolio of short and long-term holdings, professional tax advice can help ensure accurate compliance and optimal planning.
