GST on Brokerage Calculator: Rate and Worked Examples

GST on stock-broking service charges is 18%, applied to the taxable charge base rather than the full investment value. Zerodha’s tariff lists brokerage, SEBI charges and transaction charges in that base. This tool has a material limit: “Transaction Charges Rate” is treated as a rupee amount internally, without multiplying it by trade value. It also cannot reliably model a zero flat fee for non-delivery trades. Check the examples and limitations before using its totals.

What GST is charged on

GST means Goods and Services Tax. CBIC (the central indirect-tax authority) confirms that brokerage for the stock-broking service is taxable. Zerodha’s published tariff, checked on 16 October 2026, describes GST as 18% of brokerage plus SEBI regulatory charges plus transaction charges.

A security purchase and a broking service are different entries on a bill. Do not calculate GST as a percentage of the entire share purchase or the face value of a futures contract just because those amounts appear on the contract note. For the other cost categories, see brokerage and charges explained.

CBIC’s answer on stamp-duty and STT recoveries makes their exclusion conditional on the broker meeting the pure-agent rules, meaning amounts recovered on someone else’s behalf under specified conditions. That qualification matters; this page does not decide whether an individual recovery satisfies it.

Which Charges Carry GST and Which Do Not

A contract note lists many charges, and only some of them carry GST. This table follows the charges page of one large broker as logged in our charges changelog, Other brokers may word or treat a line differently, so check your own broker's page.

CBIC's published FAQ treats some recoveries (such as stamp duty and STT) as outside the GST base only when the broker acts as a pure agent. The usual contract-note layout reflects that. For how every charge is worked out, see brokerage and charges explained and non-brokerage charges.

The calculation to check against a bill

GST amount = taxable service-charge base × 18 ÷ 100. Service charges including GST = base + GST. Keep the base and the tax on separate lines. “Total with GST” is not the value of your share purchase, all trading charges or an income-tax bill.

A bill can contain other taxable services outside this small model. Use the supplier’s taxable-value breakdown rather than adding every line on a funds statement indiscriminately. A stock-broking GST calculation cannot establish eligibility to claim input tax credit or a business expense.

How this form’s controls behave

The advertised formula mentions SEBI Fees, but the visible form has no separate SEBI-fee control and the calculation does not derive that fee independently. No security name, quantity, buy/sell pair or place-of-supply control is available. The tool cannot validate a complete contract note from these inputs.

Worked tool example: isolate brokerage GST

Illustrative demonstration, not a broker tariff: use Trade Value ₹100,000, Broker Type Discount Broker (flat fee), Flat Brokerage ₹100 and Trading Segment Equity Intraday. Set Transaction Charges Rate to zero solely to isolate brokerage GST. The Brokerage Rate field is not used in this mode.

These amounts match the tool’s cards. The split into CGST and SGST is automatic; it is not a place-of-supply determination. Follow the actual invoice’s tax type rather than assuming both split cards belong on every invoice. The tool does not choose the appropriate invoice treatment.

Why the transaction-charge rate can produce the wrong amount

A rate needs both a percentage and the amount it applies to. This control is labelled as a rate but the tool adds the entered number directly to brokerage. It never converts that rate into an exchange-charge amount using Trade Value.

Illustrative unit check: a fictional service-charge rate of 0.01% on ₹100,000 corresponds to ₹10. That rate is invented for this example, not a published exchange rate. Entering 0.01 into the current field instead adds only ₹0.01 to its base. Those are different quantities.

Do not assume the preset is the applicable exchange tariff or use this field to verify an invoice rate. Work out the charge amounts independently and compare them with the broker’s bill. Until the field’s label, units and calculation agree, it cannot provide a reliable estimate from an entered rate.

A separate full-base arithmetic example

Illustrative invoice arithmetic outside the calculator: assume brokerage of ₹40, transaction charges of ₹10 and a SEBI service fee of ₹1. The chosen amounts are hypothetical. Base = ₹40 + ₹10 + ₹1 = ₹51; GST = ₹51 × 18% = ₹9.18; those services including GST total ₹60.18.

This example explains the charge base listed in Zerodha’s tariff. It is not a claim that the current form independently calculates all these charges. Keep any STT, stamp duty and other amounts on the appropriate separate lines rather than silently including them in this subtotal.

Worked Example: One Options Order With Every Charge

This example uses the rates on the charges page of one broker that we logged on 13 Oct 2026, applied to a made-up order. Suppose you sell NSE index options with a premium turnover of ₹1,00,000. It is only an illustration and not your broker's bill.

GST is ₹10.01 on a base of ₹55.63, which comes to ₹65.64 for the taxable lines together. STT of ₹150 is a separate line with no GST on it. Stamp duty applies to the buy side only, at 0.003% of the premium for options, which would be ₹3 on a ₹1,00,000 buy. This tool cannot model this order in full, because its transaction-charge field takes a rupee amount (see the sections above). Enter ₹35.53 there if you want to reproduce the base of ₹55.63 with a flat brokerage of ₹20, and add the SEBI fee yourself.

Zero brokerage and percentage brokerage are different cases

The form accepts zero in the Flat Brokerage control, but for a non-delivery segment that zero is replaced by a preset fee. It can therefore show tax on brokerage you did not intend to enter. Do not use this branch to establish a zero-brokerage bill.

The percentage branch multiplies Trade Value by Brokerage Rate and does not apply a broker’s minimum, maximum, slabs or per-order tariff automatically. A broker’s actual pricing may combine such conditions. “Discount” and “Full-service” here are arithmetic choices rather than verified descriptions of every broker in those categories.

Zero brokerage also does not establish zero GST across a real bill. Other taxable services can remain. Review the base line by line, particularly when comparing a fee promotion with actual billed charges.

Reconciling an estimate with what was charged

• Start with the applicable tariff for the specific account, product and order.
• Separate brokerage and other taxable service amounts from trade value.
• Check which amounts already include tax before adding GST.
• Compare the GST base and invoice tax type with the billed statement.
• Retain rounding and billing-period differences instead of forcing a small mismatch to zero.

For wider Indian trade-cost estimates, the F&O trading cost calculator covers a different scope. The STT calculator addresses another charge rather than GST on the broking service. Reconcile either estimate with actual records.

Keep paid charges beside each completed trade when reviewing net results. The F&O turnover explanation is a separate tax-audit topic; neither a GST base nor a contract’s face value automatically supplies that turnover.

ब्रोकरेज पर जीएसटी: सरल सार

शेयर ब्रोकरेज पर जीएसटी 18% लगता है। यह जीएसटी आपके शेयर की पूरी खरीद-बिक्री की रकम पर नहीं, बल्कि ब्रोकर की सेवा-फीस पर लगता है। इसमें ब्रोकरेज, एक्सचेंज ट्रांजैक्शन चार्ज और SEBI फीस शामिल होती है। STT और स्टैम्प ड्यूटी पर यह जीएसटी नहीं जुड़ता।

उदाहरण (काल्पनिक): अगर ब्रोकरेज ₹100 है, तो जीएसटी ₹100 x 18% = ₹18 होगा और कुल ₹118 बनेगा। जीएसटी को CGST (9%) और SGST (9%) में बराबर बांटकर दिखाया जाता है। कमीशन पर जीएसटी की दर सेवा के हिसाब से अलग हो सकती है, इसलिए अपने CA से पूछ लें।

Can Traders Claim Input Tax Credit on Brokerage GST?

Input tax credit (ITC) lets a GST-registered business subtract the GST it paid on its business costs from the GST it collects on its own sales. It does not work like an income tax deduction.

• An individual trader without a GST registration has no GST to set the credit against, so the GST on brokerage is simply a cost. It can be part of the expenses a trader reports for income tax in some cases, so ask a chartered accountant (CA).
• A GST-registered business may be able to claim credit if the brokerage relates to its taxable business supplies and the GST invoice is in the registered name. Credit rules are detailed and have conditions.
• Securities themselves are outside the GST definitions of goods and services, so GST generally does not apply to your trading profit. The GST you pay is on the broker's service.

The calculator above only works out the GST amount and its CGST and SGST split. It cannot tell you whether credit is available. Take your contract notes and GST invoices to a CA before claiming anything. Our trader tax status and tax audit for traders pages explain the income-tax side.

Where GST Appears on a Contract Note

On a contract note, GST appears as a separate line, either as CGST and SGST (central and state GST, each half of the total) or as IGST (integrated GST) when the supply crosses state lines. The broker's tax invoice also shows the broker's GST registration number and a service accounting code (SAC). Different websites quote different codes for stock broking, and we could not confirm one official code from the government's own list in this check. Use the code printed on your broker's invoice and not a code from a general article.

Did the 2025 GST Changes Affect Brokerage?

Brokers' own charges pages checked on 13 Oct 2026, including the one logged in our changelog, still show GST at 18% on brokerage and exchange charges. We could not open an official GST Council or CBIC notice on the September 2025 changes during this check, so we do not describe what that reform did for financial services. If the rate on your contract note differs from 18%, ask your broker for the notification it relies on.

GST on Commission and Brokerage for Agents

Searches for GST on brokerage and commission mix two topics. This page covers stock-broking charges paid by a trader. Commission that an agent earns, such as for insurance, mutual fund distribution or property deals, is a different supply and the rate and registration rules depend on the service. Ask a CA or check the CBIC page for that service.
