Trainer notes

Ask the room what they paid GST on this week. Most will name a restaurant bill or a phone bill. Then ask who actually sends that money to the government. This deck answers that, and explains the rate changes of September 2025.

GST taxes the value added at each step of a sale, with credit for tax already paid. The final buyer bears it.

It replaced a long list of central and state taxes on 1 July 2017. The Centre and the States levy it together, on the same sale.

Trainer notes

CBIC describes GST as a destination-based tax on consumption: the tax goes to the State where the goods or services are consumed. Keep the two ideas apart: who pays the tax to the government (each registered seller in the chain) and who bears it (the final buyer).

Four terms to know on a GST bill

  • CGST

    Central GST. Levied by the Centre on a sale of goods or services within one State.

  • SGST / UTGST

    State GST, or Union Territory GST. Levied on the same sale, at the same time as CGST.

  • IGST

    Integrated GST, on sales between States and on imports. The Centre collects it and it is shared with the States.

  • Input tax credit

    GST paid on eligible business purchases is set off against GST due on sales. Only the value added is taxed.

Sources: CBIC, Frequently Asked Questions on GST, 3rd edition, 15 Dec 2018 (Q1, Q8); Constitution of India, Article 269A.

Trainer notes

On a bill within one State you will see CGST and SGST, usually half of the rate each. On a sale across States you will see IGST at the full rate instead. Input tax credit is the feature that stops tax being charged on tax.

How the credit chain works

THE SET-UP (ASSUMED)

One rate of 18% at every step. Prices are before tax.

A mill sells cloth to a tailor for ₹1,000. The tailor sells a shirt to a shop for ₹1,500. The shop sells it to you for ₹2,000.

  1. Mill: GST on ₹1,000 = ₹180. No credit to claim. It pays ₹180.
  2. Tailor: GST on ₹1,500 = ₹270, less ₹180 credit for the GST on the cloth. It pays ₹90.
  3. Shop: GST on ₹2,000 = ₹360, less ₹270 credit. It pays ₹90.
  4. Total paid: 180 + 90 + 90 = ₹360, which is 18% of ₹2,000. With no credit it would be 180 + 270 + 360 = ₹810.

Result: Each seller pays GST only on the value it adds. You pay ₹2,360 and bear all ₹360 of the tax.

Illustration with assumed figures and a single assumed rate. Real rates differ by item.

Trainer notes

The ₹810 line shows what credit prevents: tax on tax, often called cascading. Each seller adds value of ₹1,000, ₹500 and ₹500, and 18% of each is ₹180, ₹90 and ₹90. Credit works only between registered businesses; you, as the final buyer, cannot claim it back.

What GST replaced, and what it left out

  • Central taxes replaced

    Central excise duty, service tax, additional customs duties (CVD and SAD), and central surcharges and cesses on supplies.

  • State taxes replaced

    State VAT, central sales tax, entry tax, luxury tax, purchase tax, State entertainment tax, and taxes on lotteries, betting and gambling.

  • Left outside

    Alcohol for human consumption, by the Constitution. Petrol, diesel, crude oil, natural gas and jet fuel until the GST Council recommends a date.

Sources: CBIC, FAQs on GST, 3rd edition, 15 Dec 2018 (Q3, Q5, Q6); Constitution of India, Article 279A(5) and Article 366(12A).

Trainer notes

For the five petroleum products, central excise and State VAT continue, so businesses cannot set the tax on fuel off against GST. Tobacco is within GST, and the Centre can also levy excise duty on it. Entertainment tax levied by local bodies was not subsumed.

Who decides: the GST Council

  • Members

    The Union Finance Minister chairs it. Members are the Union Minister of State for Revenue or Finance and a minister from each State.

  • 3/4

    Votes

    A decision needs three-quarters of the weighted votes cast. The Centre's vote counts for one-third; all States together, two-thirds.

  • What it recommends

    Rates, exemptions, the turnover threshold for registration, which taxes are merged into GST, and when petroleum products come in.

Source: Constitution of India, Article 279A (inserted by the Constitution (One Hundred and First Amendment) Act, 2016), as reproduced by the GST Council Secretariat.

Trainer notes

The arithmetic matters: one-third is less than three-quarters, and so is two-thirds. Neither the Centre alone nor the States alone can carry a decision. The Council recommends; the Centre and the States then notify the rates under their own GST laws. Article 279A came into force on 12 September 2016.

The rate structure since 22 September 2025

The GST Council replaced four main rates (5%, 12%, 18%, 28%) with two, plus a special rate.

The rate structure since 22 September 2025
RateUsed forExamples from the Council's list

Trainer notes

The table shows the main rates only; check the current CBIC rate schedule before quoting the rate for any specific item. Tobacco and pan masala stayed on the old rates plus compensation cess until the transition date; from 1 February 2026 they moved to 40% GST, and biris to 18%, with a new excise duty or cess alongside. The 40% rate for big cars replaced 28% GST plus a compensation cess.

GST, investors and policyholders

  • Fund expenses

    GST on a scheme's fees is a statutory levy. It is charged to the scheme on actuals and counts in the total expense ratio.

  • Nil

    Insurance premiums

    Individual life and health policies, including term, ULIP, endowment, family floater and senior citizen plans, were moved from 18% to exempt.

  • Securities

    Securities are excluded from the definitions of both goods and services, so transactions in securities are not liable to GST.

Sources: SEBI (Mutual Funds) Regulations, 2026, Reg. 66-67; PIB, 56th GST Council recommendations, 3 Sep 2025 (Annexure III) and FAQs; CBIC, FAQs on GST, 2018 (Q27).

Trainer notes

The insurance exemption applies from 22 September 2025 and covers individual policies and their reinsurance; the release does not extend it to group policies. When a supply is exempt, the supplier cannot claim credit for GST on its own inputs. GST can apply to services around investing, such as a scheme's fees (see the SEBI Regulations), but not to the securities themselves.

Where things stand

Collections are provisional government figures, as reported in the press. They are revised later.

SEPT 2026 (₹ LAKH CRORE)
2.04Gross GST, up 14.7% on Sept 2025 excluding cess. Includes imports.
APR-SEPT 2026 (₹ LAKH CR)
12.46Gross, first half of 2026-27, up 11.6% on a year earlier excluding cess.
MAIN RATES
5% / 18%Merit and standard rates since 22 September 2025, plus 40% for a select few items.

Sources: provisional government GST data, Sept 2026, via Business Today, 1 Oct 2026 (secondary); PIB, 56th GST Council recommendations, 3 Sep 2025.

Trainer notes

Gross collections are before refunds. Net collections were ₹1.77 lakh crore for September 2026, up 18.1%. The growth rates use a year-earlier base without compensation cess; September 2025 was first reported at ₹1.89 lakh crore with cess. Compare a month with the same month a year earlier, not the month before.

If you learnt this from older material

What older decks say

  • GST is a reform still to come.
  • A single proposed rate, split between the Centre and the States.
  • Four main slabs, 5%, 12%, 18% and 28%, plus a cess on sin goods.

What holds now

  • In force since 1 July 2017, after the 101st Constitution Amendment of 2016.
  • Several rates, each set on the GST Council's recommendation.
  • Since 22 September 2025: 5% and 18%, plus a 40% special rate.

Take-away: Rates change on the GST Council's recommendation. Check the date before you quote one.

Trainer notes

Material from before 2017 was written before GST began; material from 2017 to 2025 shows the old four-slab structure. The compensation cess was first meant to fund five years of compensation to States, to June 2022. It was then extended to 31 March 2026 to repay loans taken in 2020-21 and 2021-22. For tobacco and pan masala it was replaced from 1 February 2026 by 40% GST plus a new excise duty or cess.

Four things people get wrong

  • Misconception'Only the shop pays GST.'

    What is trueEach registered seller in the chain pays GST on sales, less credit for GST on purchases. The final buyer bears the total in the price.

  • Misconception'Exempt always means below 5%.'

    What is trueAn exempt seller cannot claim credit for GST on its inputs and may pass that cost on. The Council kept tractors at 5% for this reason.

  • Misconception'Petrol and diesel carry GST.'

    What is trueFive petroleum products are outside GST until the GST Council recommends a date. Central excise and State VAT apply instead.

  • Misconception'All insurance is now GST-free.'

    What is trueThe September 2025 exemption covers individual life and health policies. The Council's release does not cover group policies.

Sources: PIB, FAQs on the 56th GST Council decisions, 3 Sep 2025; CBIC, FAQs on GST, 2018 (Q5, Q6).

Trainer notes

On the second point, the Council's own FAQ explains that when goods are fully exempt, suppliers must reverse input credit, which raises their costs. On the fourth, check the current rate before quoting it for any group or commercial policy.

Check yourself

  1. Question 1: A trader buys goods for ₹10,000 plus 18% GST and sells them for ₹12,000 plus 18% GST (assumed figures). How much GST does the trader pay to the government?
