GST on F&O Brokerage vs Income Tax Turnover: Don't Confuse the Two Numbers

Short answer: Under GST, F&O trading itself is not a supply — only the brokerage you are charged is a taxable service, and you, as a client, do not charge GST on your trading profits. The ₹20 lakh GST registration threshold is measured on your own supplies (which for a pure trader are nil), not on your P&L. The income-tax turnover under s.44AB is a completely different number — the absolute sum of profits and losses on squared-off positions plus premium received on sale of options (per ICAI Guidance Note on Tax Audit — an option buyer's premium paid is not separately added). Mixing the two is one of the most common — and most publicised — retail-trader mistakes.

The two numbers, side by side

Why your trading P&L is not a GST supply

GST is charged on supply of goods or services. When you buy or sell derivatives, you are settling a financial contract, not supplying a service to your broker or the exchange. There is no output tax on your F&O profits. The only taxable transaction in the chain is the broker's service — the brokerage — which is a taxable supply of financial services at 18% GST, charged to you on the broker's invoice.

So:

• You do not charge GST on your F&O income;
• You do not include your trading P&L in your GST turnover;
• Your GST registration threshold is evaluated on your own supplies, which for a pure trader are nil — so you are not required to register on account of trading;
• The broker's GST on brokerage is your cost, not your output tax.

Can you claim input tax credit on the brokerage?

Generally no, for a pure retail trader. Input tax credit requires you to be a registered person using the input in the course or furtherance of your business. A retail trader who is not GST-registered cannot claim ITC at all. If you are registered for a separate business, the brokerage on your personal trading account is not an input used in that business, so the ITC is not claimable against it. for the edge case where an F&O business is operated through a registered entity.

The confusion, decoded

The broker's tax invoice shows GST on brokerage — a line like "GST 18% on ₹500 brokerage = ₹90." Many traders see this and conclude they are GST suppliers with a ₹90 output tax. They are not. The ₹90 is the broker's tax, collected from you and remitted by the broker to the government. It never appears in your GST returns.

The same trader, in the income-tax return, computes income-tax turnover of, say, ₹24 lakh (absolute P&L). That number goes into ITR-3's P&L and audit-applicability sections. It is unrelated to the ₹90 GST line and to the ₹20 lakh GST registration threshold.

Worked example: Neha's two numbers

Persona: Neha, FY 2025-26. F&O trading through Zerodha. Brokerage charged ₹48,000 for the year; GST at 18% ₹8,640 billed by the broker. Her net F&O profit is ₹3,20,000, and her ICAI income-tax turnover is ₹38,00,000.

GST side:

• Her supplies: nil (trading P&L is not a supply).


• Registration threshold test: ₹0 < ₹20 lakh → not required to register for GST on account of trading.


• The ₹8,640 GST on brokerage is the broker's tax, already remitted by the broker.


• She does not file GSTR-3B for her trading.

Income-tax side:

• Income-tax turnover (s.44AB test): ₹38,00,000 — below ₹1 crore (and far below ₹10 crore), so no tax audit.


• Net F&O income ₹3,20,000 reported in ITR-3 Schedule BP.

The mistake she avoided: a trader-friend told her to add the ₹8,640 GST to her GST turnover and register, and separately told her the ₹38 lakh was her "GST turnover" for the threshold. Both were wrong: ₹38 lakh is her income-tax turnover, and her GST turnover is nil.

Frequently Asked Questions

1. Do I have to pay GST on my F&O profits?

No. F&O trading P&L is not a supply of goods or services. GST applies only to the brokerage service, which your broker charges you and remits.

2. Is the ₹20 lakh GST registration threshold based on my F&O turnover?

No. The threshold counts your taxable supplies. For a pure trader, supplies are nil, so the threshold is not crossed — regardless of how large your income-tax turnover is.

3. My broker's invoice shows GST on brokerage. Am I a GST supplier?

No. The GST on brokerage is the broker's output tax, collected from you and paid by the broker. It does not make you a supplier and does not go in your GST returns.

4. Can I claim input tax credit on the brokerage I pay?

Generally no. ITC requires GST registration and use of the input in your own business. A non-registered retail trader cannot claim ITC; a registered person's personal trading brokerage is not a business input.

5. What is the difference between GST turnover and income-tax turnover?

GST turnover is the value of taxable supplies you make (nil for a client trader). Income-tax turnover under s.44AB is the absolute sum of trading profits and losses plus premium received on sale of options (per ICAI Guidance Note on Tax Audit — an option buyer's premium paid is not separately added) — used for the tax-audit test and ITR-3.

6. I am registered for GST for my consultancy. Do I report my F&O trading in GST?

Your consultancy turnover goes in your GST returns. Your personal trading P&L does not — it is not a supply of your consultancy and stays out of your GST turnover. The brokerage on the personal trading account is also not a business input.

Keep the two numbers separate

For the income-tax number, use the F&O Turnover Calculator — it computes the ICAI turnover for s.44AB, which is the figure your CA needs for the audit test. The GST number, for a pure trader, is simply nil.
