Change in Securities Transaction Tax (STT) After Union Budget 2026: What It Means for Traders

In the Union Budget 2026, the Finance Minister Nirmala Sitharaman announced an increase in Securities Transaction Tax (STT) for futures and options trading. This hike may appear marginal on paper; however, it can significantly raise trading costs for active and intraday traders. In this article, we go over what STT is, the changes post-Budget 2026 and their impact.

Securities Transaction Tax (STT) is a tax levied by the Indian government on the buying and selling of securities carried out on recognised stock exchanges. STT applies to equity shares, futures and options.

The tax is automatically deducted at the time of the transaction and is visible in your contract note. You do not need to pay it separately.

Explained below are the characteristics of STTs:

• STTs are charged regardless of profit or loss. Even losing trades attract STT. 

• STT is a transaction-based tax. Therefore, higher trading frequency leads to higher STT outgo.

• Futures, options premium and option exercise each have separate STT rates. 

• STT cannot be reclaimed or offset later.

Because STT is a fixed and unavoidable cost, even small increases can materially affect trading profitability. 

STT on futures is charged only on the sell side, but the increase is substantial.

Example: Futures Trade 

• Contract value: ₹1,00,000

• Earlier STT: ₹1,00,000 × 0.02% = ₹20 

• New STT: ₹1,00,000 × 0.05% = ₹50

• Additional cost per trade: ₹30 

Options traders face a double impact:

• Higher STT on options premium

• Higher STT on option exercise at expiry
   

Example 1: Selling Options Premium

• Premium received: ₹50,000

• Earlier STT: ₹50,000 × 0.10% = ₹50 

• New STT: ₹50,000 × 0.15% = ₹75

• Extra cost per trade: ₹25
   

Example 2: Option Exercise at Expiry

• Settlement value: ₹50,000

• Earlier STT: ₹50,000 × 0.125% = ₹62.5

• New STT: ₹50,000 × 0.15% = ₹75

• Additional cost at exercise: ₹12.5

While this looks small, traders who sell multiple lots daily will see costs add up quickly.

Individuals investing in stocks for the long-term may not be impacted by STT a lot. However, when you’re buying and selling stock daily or are trading higher volumes, you may feel the ramifications at a higher level:

• Intraday & High-Frequency Traders: Multiple trades magnify STT impact and thin-margin strategies may stop working.

• Options Sellers: Higher cost on every premium earned

The STT hike post Union Budget 2026 may increase friction costs in derivatives trading. While the intent may be to curb excessive speculation and boost revenue, traders must now adapt by focusing on higher-conviction trades and reduced overtrading.
