Goods and Services Tax

Goods and Services Tax is a tax on consumption. Three ideas in the workbook's definition carry the whole thing.

Destination-based. The tax follows where the goods are consumed, not where they were made.

All stages. It is levied at every stage, right from manufacture up to final consumption.

Credit. Tax paid at an earlier stage is available as a setoff. So each business is taxed only on the value it adds.

GST arrives under three names. The Centre levies CGST on an intra-state supply of goods or services. The state levies SGST on the same supply. On an inter-state supply the Centre levies and administers IGST instead.

In commodity derivatives GST turns up in two quite different places. The seller of goods charges it to the buyer when delivery is billed. And your broker and your exchange charge it on their own fees.

Where it bites on a delivery. In commodity derivatives, GST is levied by the seller of goods on the buyer of goods at the time of billing for delivery. It is levied at the point of delivery of goods, after assignment of delivery obligations, and it is charged on the billed amount, which is the Final Settlement Price of the goods to be delivered. A cash-settled position never reaches that point.

Where it bites on a service. Brokerage charged by brokers, and the trading or clearing fee charged by exchanges, also attract GST. Chapter 6 lists GST among the four statutory charges on a commodity trade, alongside Commodity Transaction Tax, stamp duty and SEBI turnover fees.

What GST swallowed and what it did not. It subsumed Excise, Sales Tax, Octroi and Mandi Tax. It did not subsume Mandi Cess and Customs Duty. This is examined, and the near-identical pair — Mandi Tax in, Mandi Cess out — is the reason.

That surviving Mandi Cess shows up in the polling process. Polled agricultural spot prices are ex-warehouse prices inclusive of Mandi Cess but exclusive of GST, which is why GST has to be added on top of the FSP at billing rather than being already inside it.

The rate — and the honest answer. The workbook deliberately does not state a GST rate. It says the applicable rate shall be charged in accordance with the latest amendments to GST rates notified by the Government, including amendments effective as of September 2025. So the rate text gives no percentage to memorise — though the workbook's own Chapter 6 cost example (p137) computes GST @ 18% on brokerage and transaction charges. The levies whose figures this chapter does fix are the other three: CTT at 0.01% on the sale of a commodity or commodity index future, 0.05% on the sale of an option, 0.0001% on exercise leading to delivery and 0.125% on exercise settled otherwise than by delivery; stamp duty at a uniform Rs 2 per Rs 1 lakh, about 0.002%; and SEBI turnover fees at Rs 15 per Rs 1 crore, reduced to Rs 1 per crore for agricultural commodities.

One structural gap. The exchange does not deal with IGST at all — it collects only CGST and SGST, at final settlement of the delivery. See inter-state delivery problem.

Meenakshi Agro Pvt Ltd is assigned delivery of 10 MT of guar gum — 100 quintals — at a Final Settlement Price of Rs 6,000 per quintal. The billed amount is therefore Rs 6,00,000, and that is the base on which the seller charges GST.

Run every statutory charge on the same Rs 6,00,000 and see where GST sits:

Guar gum is a processed agricultural commodity, so CTT does apply — the workbook names Sugar, Guar gum and Soya Oil alongside all metal and energy derivatives as CTT-liable. Unprocessed agricultural derivatives are exempt.

Notice the two GST rows. One is on goods, charged by the selling member to the buying member when the delivery is invoiced at the FSP. The other is on a service, charged by the broker on its own brokerage. Both are GST; neither is collected by the same person.

And notice what is missing from the table: a rupee figure for GST. The workbook refuses to fix the rate, so a candidate should compute the other three and leave GST as a rate applied to Rs 6,00,000.

Chapter 9 (Accounting and Taxation), section 9.4.4, and Chapter 6 (Trading Mechanism), section 6.7, which lists GST among the statutory charges.

Two of Chapter 9's own sample questions are on this page. One is the definition, near-verbatim: ____ is a destination-based tax on consumption of goods and services which is levied at all stages right from manufacture up to final consumption with credit of taxes paid at previous stages available as setoff — Goods and Services Tax. The other asks what is levied and administered by the Centre on every inter-state supply — IGST. Beyond those, expect the subsumption list and the point that GST is charged on the FSP at the time of billing for delivery.

• Mandi Cess and Customs Duty are NOT subsumed; Mandi Tax is. One word apart, opposite answers, and this is the single most examinable line in the section.
• CGST plus SGST for intra-state, IGST for inter-state. IGST is levied and administered by the Centre, not shared at the point of levy.
• GST is charged on the billed amount, which is the FSP — not on the traded price, and not on the contract value when the position was opened.
• The workbook gives no GST rate. It points to the rates notified by the Government, including amendments effective as of September 2025. Do not carry a percentage into the exam from this paper. CTT, stamp duty and SEBI turnover fees are the levies whose numbers you must know.
• Delivery GST needs a delivery. A cash-settled contract never generates it — though brokerage and exchange fees still attract GST either way.
• Polled agri spot prices are inclusive of Mandi Cess but exclusive of GST. Treating a poll as GST-inclusive corrupts every figure built on the FSP.
• GST is not CTT. Different base, different payer, different rate structure, and CTT is a securities-market-style levy while GST is a consumption tax.
• The exchange handles only CGST and SGST, which is what creates the inter-state delivery problem.
