GST on Share Trading & F&O: What Every Trader Must Know

Every contract note carries a line marked "GST." Most traders never check what it is charged to. Many fear that GST on share trading taxes the whole trade value. It does not. Knowing where the 18% lands and where it does not helps a trader read costs right and claim the correct deductions at tax time.

Does GST apply to buying and selling shares?

No. The GST law keeps securities out of its scope on purpose. Under the CGST Act, 2017, the meaning of "goods" in Section 2(52) and "services" in Section 2(102) both leave out securities. Shares, futures, options, bonds, and units are all securities. So buying or selling them is neither a supply of goods nor a supply of services.

The result is simple. When a trader buys shares worth two lakh rupees, GST is charged on zero of that value. The same holds for futures and options. The trade value, the premium, and the profit are all free of GST.

So where does the 18% actually hit?

GST sits on the service of running a trade, not the trade itself. A broker, an exchange, and a depository each provide a service. Those services are taxed at the standard 18% rate. The charges that attract GST are:

• Brokerage: the broker's fee per order
• Exchange transaction charges: levied by NSE or BSE
• SEBI turnover fees: the regulator's levy
• DP charges and demat AMC: the depository's fees
• Other service fees: call-and-trade, payment gateway, and similar

The charges that do not attract GST are the government's own levies: the Securities Transaction Tax (STT) and stamp duty. A tax cannot be taxed again, so these sit outside GST.

A worked example on an F&O trade

Suppose a trader sells one lot of Nifty options. The premium value of the position is ₹40,000. On a discount broker, the charges might look like this:

• Brokerage: ₹20
• Exchange transaction charges: about ₹14
• SEBI turnover fee: a few paise

GST is charged on the sum of these service fees, about ₹34. At 18%, the GST comes to roughly ₹6. The STT on the sell side is 0.1% of the premium, or ₹40, and it carries no GST. So on a ₹40,000-rupee position, the GST is ₹6, charged on services, never on the premium.

The lesson is clear. GST grows with how often a trader trades, not with how big the position is. A trader who places hundreds of orders a day pays far more GST in a year than an investor who moves the same rupee value once.

Does GST differ across intraday, delivery, and F&O?

The GST rate is the same 18% across all three. What changes is the size of the charges it sits on. F&O and intraday create many more orders. Because GST rides on brokerage and transaction charges, an active F&O book usually carries the biggest GST bill, simply due to order count. The structure stays the same: 18% on services, nothing on the trade value. For more on how these costs work together, see Sahi's guide to income tax on F&O trading.

Can a trader claim input tax credit on this GST?

This is where most traders go wrong. Input tax credit (ITC) lets a registered business set off GST paid on its inputs against GST charged on its sales. The catch is that trading in securities is not a taxable sale. There is no GST output to set the credit against. So a pure securities trader cannot register for GST on trading and cannot claim ITC on the GST paid on brokerage.

A retail investor who reports gains as capital gains clearly cannot claim it. The one narrow case is a person already GST-registered for a separate taxable business who can show the service was used for that business. 

There is a more useful point. Even when ITC is not available, GST on brokerage is still a deductible business expense for anyone who reports F&O or intraday profit as business income. It cuts taxable profit, though not GST itself. Sahi's note on income tax on intraday trading covers which charges can be deducted.

GST 2.0 (September 2025): Did anything change for traders?

The GST 2.0 reform took effect on 22 September 2025. It cut most rates into a 5% and 18% structure, with a 40% slab for a few items. Financial services, including brokerage, stayed in the 18% slab. For traders, nothing on the contract note moved. The 18% on charges runs exactly as before. The reform made rates simpler elsewhere, but trading costs were already at 18% and stay there.

Mistakes traders make with GST

• Believing GST is charged on turnover. It is charged on service fees only. A six-rupee GST on a ₹40,000-rupee trade is normal.
• Confusing GST with STT. Both appear on the contract note, but STT is a separate government tax and carries no GST.
• Assuming ITC is available. Most traders cannot claim it because securities trading is not a taxable supply.
• Ignoring GST in the cost ledger. Across thousands of orders, GST on brokerage adds up; business-income traders should book it as a deductible expense.

Traders watching their full tax picture should also track the rising STT load. We have covered the recent change in the STT hike explained and the wider regulatory shifts in its overview of tax and regulatory impact on active traders.
