Securities Transaction Tax (STT) on share sales is not deductible if income is taxed as capital gains under Section 48 — but traders reporting business income can claim it under Section 36(1)(xv). The answer depends on whether you are an investor or a trader.
The Short Answer
Now let us understand why.
Scenario 1: Income Taxed as Capital Gains
Most retail investors report profit or loss from selling shares under the head Capital Gains — either as Short-Term Capital Gains (STCG) or Long-Term Capital Gains (LTCG), depending on the holding period.
Capital gains are computed under Section 48 of the Income Tax Act, which allows certain deductions from the sale consideration — namely, the cost of acquisition, cost of improvement, and expenses incurred wholly and exclusively for the transfer.
However, the seventh proviso to Section 48 carves out a specific exception: it expressly states that no deduction shall be allowed for any amount paid as Securities Transaction Tax while computing income chargeable under the head Capital Gains.
This means that even though STT is a genuine transaction cost, the law does not permit you to reduce your capital gains by the STT amount paid — neither on purchase nor on sale. You simply cannot add it to your cost of acquisition or subtract it as a selling expense.
Scenario 2: Income Taxed as Business Income
If you are a trader — someone who buys and sells shares frequently and treats them as stock-in-trade rather than investments — your profits are taxed under the head Profits and Gains of Business or Profession, not Capital Gains.
In this case, a different provision applies: Section 36(1)(xv). This section explicitly allows a deduction for STT paid on taxable securities transactions, provided:
- 1The transactions are entered into in the course of business, and
- 2The income from such transactions has been included while computing business income.
So, if you are classified as a trader, both your STT and your brokerage charges can be claimed as legitimate business expenses, reducing your taxable business income.
Why the Classification Matters So Much
This is why one of the most important — and often contested — questions in share-related taxation is: are you an investor or a trader? The Income Tax Department looks at several factors to decide this, including:
- 1Frequency and volume of transactions.
- 2Holding period of shares.
- 3Intention behind the purchase (investment vs. profit from trading).
- 4Whether shares are held as capital assets or stock-in-trade in your books.
- 5Source of funds (own funds vs. borrowed funds).
Many active traders prefer being classified as traders precisely because it unlocks deductions — like STT, brokerage, internet charges, advisory fees, and even a portion of office or equipment costs — that are not available under the Capital Gains regime.

Key Takeaway
If you are unsure which category your transactions fall into, it is worth consulting a tax professional, since misclassification can lead to disputes with the tax department and denial of deductions you may have already claimed.

Quick answers
Direct answers to common questions on this topic.
Can STT be deducted when share profits are taxed as capital gains?
No. The seventh proviso to Section 48 expressly disallows any deduction for STT paid while computing income chargeable under the head Capital Gains. STT cannot be added to cost of acquisition or deducted as a selling expense.
Can share traders deduct STT on their transactions?
Yes. Under Section 36(1)(xv), STT paid on taxable securities transactions is deductible as a business expense if the transactions are entered into in the course of business and the income has been included while computing business income.
What is the difference between investor and trader treatment for STT?
Investors holding shares as capital assets report STCG or LTCG and cannot deduct STT. Traders treating shares as stock-in-trade report business income and can deduct STT along with brokerage, advisory fees, and other business expenses.
Can brokerage be deducted if shares are taxed as capital gains?
Yes. Brokerage and other expenses incurred wholly and exclusively for the transfer of a capital asset can be deducted under Section 48 while computing capital gains — unlike STT, which is specifically barred by the seventh proviso.
