What Is GST?
GST is a comprehensive, multi-stage, destination-based indirect tax levied on every value addition in the supply chain. It replaced multiple cascading taxes (excise duty, service tax, VAT, CST, octroi, entry tax, luxury tax, etc.) with a single unified tax.
"One Nation, One Tax, One Market"
| Feature | Detail |
|---|---|
| Launched | 1 July 2017 (midnight session of Parliament) |
| Constitutional basis | 101st Constitutional Amendment Act, 2016 (inserted Article 246A, 269A, 279A) |
| Replaces | Central Excise, Service Tax, VAT, CST, Octroi, Entry Tax, Purchase Tax, Luxury Tax, Entertainment Tax, and others |
| Does NOT cover | Petroleum products (crude oil, natural gas, ATF, petrol, diesel), alcoholic liquor for human consumption, electricity |
Key distinction: Petroleum and alcohol are excluded from GST for fundamentally different reasons. Alcohol is excluded by the Constitution itself (Article 246A(1) — states retain exclusive power). Petroleum products are technically within GST's scope but the GST Council has not yet notified a date for their inclusion — this is a political decision, not a constitutional bar. So petroleum CAN be brought under GST by Council recommendation; alcohol CANNOT without a Constitutional Amendment. This distinction is a Prelims trap.
Constitutional Framework
Key Articles Inserted by 101st Amendment
| Article | Provision |
|---|---|
| 246A | Both Parliament and State Legislatures have power to make laws on GST |
| 269A | IGST on inter-state supply — levied and collected by Centre; shared with consuming state |
| 279A | Establishment of the GST Council |
| Article 366(12A) | Definition of GST |
| Seventh Schedule | Entry 84 of Union List and Entry 54 of State List amended |
GST Council (Article 279A)
| Feature | Detail |
|---|---|
| Nature | Constitutional body; joint forum of Centre and States |
| Chairperson | Union Finance Minister |
| Members | Union Minister of State for Finance + Finance Minister of each State/UT with legislature |
| Voting | Centre has 1/3rd weightage; States collectively have 2/3rd weightage |
| Quorum | 50% of total members |
| Decision | By 3/4th majority of weighted votes |
| Recommendations | On GST rates, exemptions, model laws, threshold limits, dispute resolution |
Exam Tip: The GST Council's voting design ensures neither Centre nor States can unilaterally push through decisions. Centre has 1/3rd votes, so it CANNOT reach 3/4th alone. States collectively have 2/3rd, which is also less than 3/4th. This forces consensus — a deliberate cooperative federalism feature. But after the Mohit Minerals (2022) ruling, even this consensus is advisory, not binding. For Mains, connect this to the broader Centre-State fiscal autonomy debate.
Union of India v. Mohit Minerals (2022): The Supreme Court held that GST Council's recommendations are not binding on Centre or States — they are persuasive. This preserves cooperative federalism.
GST Structure
Types of GST
| Type | Levied by | On |
|---|---|---|
| CGST (Central GST) | Central Government | Intra-state supply |
| SGST (State GST) | State Government | Intra-state supply |
| IGST (Integrated GST) | Central Government | Inter-state supply and imports |
| UTGST (UT GST) | Union Territory | Intra-state supply within UTs without legislature |
Example: A Rs. 100 product sold within Maharashtra at 18% GST → 9% CGST (to Centre) + 9% SGST (to Maharashtra). If sold from Maharashtra to Gujarat → 18% IGST (collected by Centre, consuming state's share transferred to Gujarat).
GST Rate Slabs
Original Structure (2017–2025)
| Rate | Items |
|---|---|
| 0% | Essential food items (rice, wheat, milk, fresh vegetables), healthcare, education |
| 5% | Packaged food items, transport services, small restaurants |
| 12% | Processed food, business class air tickets, apparel above Rs. 1,000 |
| 18% | Standard rate — most goods and services (electronics, financial services, restaurants in hotels) |
| 28% | Luxury and demerit goods (cars, AC, aerated drinks, tobacco, cement) + Compensation Cess |
GST 2.0 Reforms (56th GST Council, 3 September 2025; effective 22 September 2025)
Major simplification — the 12% and 28% slabs were eliminated. The new structure has 3 effective tax rates (plus exempt):
| New Rate | Coverage |
|---|---|
| 0% | Essentials — unpackaged food, fresh produce, milk, education, health services |
| 5% | Merit goods — packaged food, processed food (99% of old 12% slab moved here), transport |
| 18% | Standard rate — most goods and services (90% of old 28% slab moved here); electronics, ACs, TVs, cement moved down from 28% |
| 40% | Demerit/luxury goods — luxury vehicles, aerated drinks, tobacco, gambling |
Other key reforms: life and health insurance exempted from GST; automated risk-based refund system (90% provisional refund for exporters from 1 November 2025); GSTAT (GST Appellate Tribunal) operationalised.
Input Tax Credit (ITC)
The backbone of GST — eliminates cascading (tax-on-tax) effect.
- ITC allows a business to claim credit for GST paid on inputs (raw materials, services) against the GST collected on output (sales)
- Only available for registered taxable persons
- Conditions: Must have a valid tax invoice; goods/services must be used for business purposes; supplier must have filed returns
- Inverted duty structure — when input tax rate > output tax rate, taxpayer can claim refund
Common Mistake: Aspirants assume GST completely eliminated cascading. It did not — since petroleum, alcohol, and electricity are outside GST, businesses using these as inputs (e.g., transport companies buying diesel, restaurants buying liquor) CANNOT claim ITC on them. This creates a "broken chain" in the credit mechanism, effectively reintroducing cascading for these inputs. This is one of the strongest arguments for including petroleum under GST.
GST Compensation Cess
- Purpose: Compensate states for revenue loss due to GST implementation
- Duration: 5 years (2017–2022); extended to March 2026 to repay borrowings made during COVID-19
- Base year: 2015-16 revenue with 14% annual growth guaranteed
- Levied on: Luxury and sin goods (tobacco, aerated drinks, motor vehicles, coal)
- Issue: Centre borrowed Rs. 2.69 lakh crore on behalf of states during COVID; cess continues to repay this

Impact of GST
Positives
- One market — eliminated inter-state barriers, reduced logistics costs
- Reduced cascading — ITC mechanism ensures tax only on value addition
- Improved compliance — digital trail through GSTN
- Revenue buoyancy — GST collections crossed Rs. 2 lakh crore/month in FY26

- Consumer benefit — lower prices for many goods due to eliminated cascading
Challenges
- Complexity for small businesses — multiple returns, technology adoption
- Petroleum exclusion — biggest revenue item still outside GST
- Compensation cess extension — created fiscal strain
- Rate rationalisation — frequent changes create uncertainty
- Inverted duty structure — refund delays for exporters and certain sectors
Vocabulary
CGST
- Pronunciation: /siː-dʒiː-ɛs-tiː/
- Definition: Central Goods and Services Tax — the central government's share of tax on intra-state supplies
- Explanation: CGST is levied by the Central Government on every intra-state supply of goods and services. It is collected alongside SGST (or UTGST) so that both Centre and State receive revenue from the same transaction. For example, if a Delhi shopkeeper sells goods to a Delhi customer at 18% GST, 9% goes as CGST to the Centre and 9% as SGST to Delhi.
- Origin: Acronym from Central (Latin centralis, relating to the centre) + Goods and Services Tax. The term was coined by the 101st Constitutional Amendment Act, 2016, which inserted Article 246A empowering both Centre and States to levy GST.
- Synonyms: Central tax (used interchangeably in the CGST Act, 2017) — both refer to the same levy; no practical difference
- Antonyms: SGST (State GST) — the state counterpart levied alongside CGST on the same transaction; IGST — the integrated tax that replaces both CGST and SGST on inter-state transactions
- UPSC: GS3 — Indian Economy, Fiscal Federalism; Prelims (distinguish CGST/SGST/IGST/UTGST), Mains (Centre-State fiscal relations under GST)
- Related: [[SGST]], [[IGST]], [[Dual GST]]
Input Tax Credit
- Pronunciation: /ˈɪnpʊt tæks ˈkrɛdɪt/
- Definition: Credit available to a registered person for GST paid on inputs (goods/services) used in furtherance of business
- Explanation: Under Section 16 of the CGST Act, 2017, every registered person is entitled to claim credit of input tax charged on inward supplies that are used in the course of business. This mechanism ensures tax is levied only on value addition at each stage, not on the cumulative value — thereby eliminating the cascading effect (tax-on-tax). For instance, a manufacturer paying 18% GST on raw materials can set off this amount against the GST collected on finished goods.
- Origin: Input (goods/services acquired for use in production) + Tax Credit (a deduction against tax liability). The concept existed in pre-GST indirect taxes (CENVAT credit, VAT input credit) but was fragmented across Centre and State levies. GST unified it into a seamless national credit chain.
- Synonyms: ITC (standard abbreviation used in the Act and GST returns); CENVAT Credit (the pre-GST equivalent under Central Excise — narrower, covered only central taxes)
- Antonyms: Output tax (the GST collected on outward supplies, against which ITC is set off); Exempt supply (no ITC can be claimed on inputs used for exempt supplies)
- UPSC: GS3 — Taxation, Economic Reforms; Prelims (ITC conditions, Section 16), Mains (how ITC eliminates cascading effect, ITC fraud issues, inverted duty structure problems)

E-way Bill
- Pronunciation: /iː-weɪ bɪl/
- Definition: Electronic Way Bill — a mandatory digital document for transporting goods valued above Rs 50,000
- Explanation: Introduced on 1 April 2018 for inter-state movement and phased in for intra-state movement, the E-way Bill is generated on the common GST portal before goods are dispatched. It tracks goods in transit to prevent tax evasion, replacing the multiple waybill systems that existed under state VAT regimes. Every consignment of goods exceeding Rs 50,000 in value must have an E-way Bill, which is valid for a distance-based time period.
- Origin: E-way is short for Electronic Way — a digital adaptation of the traditional waybill (a document listing goods in a shipment, from way + bill of lading). The concept was mandated under Rule 138 of the CGST Rules, 2017.
- Synonyms: Electronic waybill (formal name); transit pass (informal, used in pre-GST state VAT systems — but these were state-specific and not electronic)
- Antonyms: No direct antonym; the absence of an E-way Bill for sub-Rs 50,000 consignments is simply an exemption, not a separate concept
- UPSC: GS3 — GST compliance infrastructure; Prelims (threshold limit of Rs 50,000, inter-state mandatory date), Mains (role in reducing tax evasion, logistic efficiency, ease of doing business)

Anti-profiteering
- Pronunciation: /ˌæntɪ-ˈprɒfɪtɪərɪŋ/
- Definition: Legal mandate under Section 171 of CGST Act requiring businesses to pass on benefits of GST rate reductions or ITC gains to consumers
- Explanation: When GST rates are reduced or when a business gains additional ITC benefits due to GST implementation, Section 171 mandates that such benefits must be passed on to consumers through commensurate price reductions. The National Anti-Profiteering Authority (NAA) was constituted to examine complaints. The GST Council recommended a sunset clause for anti-profiteering with effect from 1 April 2025, with the Competition Commission of India (CCI) handling residual cases.
- Origin: Anti- (Greek anti, against) + profiteering (making excessive profits, from profit — Latin profectus, advancement). The concept draws from wartime price control laws; in the GST context, it was borrowed from Malaysia and Australia's GST implementation models.
- Synonyms: Price pass-through mandate (descriptive term used in economic analysis); no exact synonym exists in Indian tax law
- Antonyms: Price gouging (the practice anti-profiteering aims to prevent); profiteering (excessive profit-making that this provision targets)
- UPSC: GS3 — Consumer protection, GST governance; Prelims (Section 171, NAA, CCI takeover), Mains (effectiveness of anti-profiteering, comparison with other countries' GST models)
- Related: [[GST Compensation]], [[Composition Scheme]]
GSTN
- Pronunciation: /dʒiː-ɛs-tiː-ɛn/
- Definition: Goods and Services Tax Network — the IT infrastructure backbone that processes all GST registrations, returns, and payments
- Explanation: GSTN is a Section 8 (not-for-profit) company set up to provide shared IT infrastructure and services to Central and State governments, tax payers, and other stakeholders. It manages the GST portal (gst.gov.in) where all GST compliance — registration, return filing, tax payment, refund processing, and E-way Bill generation — takes place. Initially, the Centre held 24.5% equity and states held 24.5%, with the remaining 51% held by private institutions. In 2018, the government converted GSTN into a fully government-owned entity (50% Centre, 50% States collectively).
- Origin: Acronym from Goods and Services Tax Network. Incorporated on 28 March 2013, well before GST launch, to build the technology platform.
- Synonyms: GST portal (refers specifically to the website, not the company); GST common portal (the legal term used in the CGST Act for the electronic platform)
- Antonyms: No direct antonym; the pre-GST equivalent was fragmented — ACES (for Central Excise) and state-specific VAT portals
- UPSC: GS3 — Digital governance, IT in taxation; Prelims (ownership structure, Section 8 company status), Mains (role of technology in tax reform, GSTN's role in cooperative federalism)

Key Terms
Cascading Effect
- Pronunciation: /kæˈskeɪdɪŋ ɪˈfɛkt/
- Definition: The tax-on-tax problem in indirect taxation where each successive stage of production or distribution levies tax on a value that already includes taxes paid at earlier stages, resulting in an inflated final price for the consumer. Before GST, India's fragmented tax system (Central Excise + State VAT + Service Tax + CST + Octroi) had no cross-credit mechanism — a manufacturer paying 12% excise could not claim credit against 14% VAT on sale, and service tax credits could not offset excise or VAT liabilities, compounding the effective tax burden by an estimated 25-30% above the nominal rate.
- Context: India's pre-GST indirect tax regime imposed multiple taxes at different stages with limited or no cross-credit: Central Excise on manufacture, State VAT on intra-state sale, CST on inter-state sale, service tax on services, plus octroi, entry tax, luxury tax, and entertainment tax. Since businesses could not claim credit across these different taxes (e.g., CENVAT credit did not offset VAT; VAT credit did not offset CST), the effective tax rate was much higher than the nominal rate. GST (launched 1 July 2017) addressed this through a seamless Input Tax Credit (ITC) mechanism under Section 16 of the CGST Act, 2017, allowing full credit of all GST paid on inputs against GST collected on outputs across the supply chain. However, cascading is NOT fully eliminated — petroleum products, alcohol, and electricity remain outside GST, so businesses using these as inputs (transport companies buying diesel, restaurants buying liquor) cannot claim ITC on them, creating a "broken chain" in the credit mechanism.
- UPSC Relevance: GS3 Economy — Prelims: what cascading means (tax-on-tax), how ITC under GST prevents it (credit of input tax against output tax), which items remain outside GST and still cause cascading (petroleum, alcohol, electricity); Mains: pre-GST vs post-GST tax burden analysis (estimated 2-3% GDP gain from eliminating cascading), impact on prices and consumer welfare, why petroleum must be brought under GST to complete the ITC chain, comparison with cascading elimination in other VAT/GST countries.
Dual GST
- Pronunciation: /ˈdjuːəl dʒiː-ɛs-tiː/
- Definition: India's unique concurrent dual GST model where both the Central Government (CGST) and State Governments (SGST/UTGST) levy tax simultaneously on the same intra-state supply of goods and services, while a single Integrated GST (IGST) is levied by the Centre on inter-state supplies and imports, with the consuming state's share apportioned to it. This was mandated by the 101st Constitutional Amendment Act, 2016 (assented 8 September 2016), which inserted Article 246A granting concurrent taxing power to both Centre and States.
- Context: The idea of a nationwide GST was first proposed by the Kelkar Task Force on Indirect Taxes (2000); the Twelfth Finance Commission (2005) endorsed it. The Empowered Committee of State Finance Ministers (chaired by Asim Dasgupta) refined the dual model through years of Centre-State negotiations. India chose the dual model — rather than a unified single GST like Singapore or New Zealand — to preserve states' constitutional right to tax and protect their revenue autonomy, given that states depended heavily on VAT, CST, and other indirect taxes. Canada's federal-provincial GST (GST + PST/HST) served as a reference model. Under the dual structure: intra-state supply attracts CGST (to Centre) + SGST (to State) at equal rates; inter-state supply attracts IGST (collected by Centre, destination state's share transferred). The GST Council (Article 279A) — with Centre holding 1/3rd voting weight and States collectively 2/3rd, decisions by 3/4th majority — ensures consensus-based rate-setting. After the Supreme Court's Mohit Minerals ruling (2022), the Council's recommendations are persuasive, not binding, preserving cooperative federalism.
- UPSC Relevance: GS3 Economy — Prelims: dual GST means concurrent levy by Centre (CGST) and State (SGST) on same transaction, 101st Amendment (2016), Article 246A (concurrent power), IGST for inter-state supply, Kelkar Task Force (2000) first proposed GST, GST Council (Article 279A) — Centre 1/3rd, States 2/3rd, 3/4th majority; Mains: why India chose dual model over unified GST (federal structure, state revenue autonomy), comparison with Canada (dual) vs Singapore/NZ (unified) models, has dual GST strengthened or weakened state fiscal autonomy, Mohit Minerals (2022) implications — Council recommendations are advisory, not binding, impact on cooperative federalism.
Composition Scheme
- Pronunciation: /ˌkɒmpəˈzɪʃən skiːm/
- Definition: A simplified GST compliance scheme under Section 10 of the CGST Act, 2017, for small taxpayers with aggregate turnover up to Rs. 1.5 crore (Rs. 75 lakh for special category states — North-East and Himachal Pradesh), allowing them to pay tax at low flat rates (1% for manufacturers, 5% for restaurants, 0.5% for other suppliers) without the complexity of regular GST returns, but without eligibility to claim Input Tax Credit or make inter-state supplies. A separate provision for service providers with turnover up to Rs. 50 lakh allows composition at 6% (3% CGST + 3% SGST).
- Context: Introduced under Section 10 of the CGST Act, 2017, the Composition Scheme is a voluntary opt-in mechanism aimed at reducing compliance burden for micro and small businesses. Taxpayers opting for the scheme file a single quarterly return (CMP-08) and an annual return (GSTR-4), instead of the monthly GSTR-1 and GSTR-3B required of regular taxpayers. Key restrictions: no ITC claims, no inter-state supply, no e-commerce supply, and every bill must carry the words "composition taxable person, not eligible to collect tax on supplies." The Finance Act 2025 introduced further amendments to Section 10, including easing intra-state operations and relaxing the service cap to 15% for mixed suppliers. The scheme mirrors the Composition Levy that existed under earlier State VAT laws. Taxpayers can opt in using Form CMP-02 by 31 March of the preceding year (e.g., by 31 March 2026 for FY 2026-27). The scheme is critical for formalising small businesses — millions of micro enterprises use it as their entry point into the formal GST framework.
- UPSC Relevance: GS3 Economy — Prelims: Section 10 of CGST Act, turnover limit Rs. 1.5 crore (Rs. 75 lakh for special category states), flat rates (1% manufacturers, 5% restaurants, 0.5% others, 6% for service providers up to Rs. 50 lakh turnover), no ITC eligibility, no inter-state supply allowed, quarterly filing (CMP-08); Mains: has the Composition Scheme helped MSMEs reduce compliance burden (yes — simpler returns, lower rates; no — loss of ITC makes them uncompetitive against regular taxpayers), trade-off between simplification and ITC denial, role in GST formalisation of the informal sector, should the threshold be raised further to cover more businesses.
Zero-rated Supply
- Pronunciation: /ˈzɪəroʊ-reɪtɪd səˈplaɪ/
- Definition: Supplies taxed at 0% GST under Section 16 of the IGST Act where the supplier retains full eligibility to claim Input Tax Credit (ITC) refund on all inputs, ensuring the entire supply chain is free of domestic tax. Only two categories qualify: (1) exports of goods and services, and (2) supplies to Special Economic Zones (SEZ developers and units). The critical distinction from exempt supplies is that zero-rated suppliers can claim full ITC refund, while exempt suppliers cannot — making zero-rating export-friendly and exemption export-neutral.
- Context: Section 16(1) of the IGST Act defines zero-rated supplies. The mechanism ensures Indian exports are completely free of embedded domestic taxes, maintaining the destination-based principle — goods consumed abroad should bear the tax of the destination country, not India's GST. Exporters have two compliance options: (a) supply under a Bond or Letter of Undertaking (LUT) without paying IGST and claim refund of accumulated ITC; or (b) pay IGST at the time of export and claim refund of the IGST paid. The Finance Bill 2026 (Clause 141) proposed deletion of Section 13(8)(b) of the IGST Act, which previously caused certain Indian intermediary services (BPOs, agencies serving foreign clients) to be treated as domestic supplies — once deleted, these services qualify as exports and become zero-rated under Section 16. Automated risk-based refunds (90% provisional refund for exporters from 1 November 2025) under GST 2.0 reforms have significantly reduced the refund timeline, improving export working capital.
- UPSC Relevance: GS3 Economy — Prelims: Section 16 of IGST Act, only two categories (exports + SEZ supplies), zero-rated vs exempt supply (classic UPSC trap — zero-rated allows ITC refund, exempt does NOT), two options for exporters (LUT without payment + ITC refund, or pay IGST + claim IGST refund); Mains: impact of zero-rating on India's export competitiveness (ensures no domestic tax embedded in export prices), inverted duty structure and refund delays as challenges for exporters, SEZ policy and GST — are SEZ benefits being eroded, Finance Bill 2026 Section 13(8)(b) deletion — expanding the scope of zero-rated services exports.
GST Compensation
- Pronunciation: /dʒiː-ɛs-tiː ˌkɒmpɛnˈseɪʃən/
- Definition: A constitutional guarantee under the 101st Amendment Act, 2016, and the GST (Compensation to States) Act, 2017, that the Centre would compensate states for any revenue shortfall from GST implementation by assuring 14% compounded annual growth over a base year of 2015-16 revenue, for an initial period of five years (July 2017 to June 2022). The compensation was funded through a dedicated GST Compensation Cess levied on luxury and demerit goods (pan masala, tobacco, coal, motor vehicles, aerated beverages). The cess has been extended to 31 March 2026 to repay Centre's borrowings made during the COVID-19 pandemic.
- Context: States surrendered their independent power to levy multiple indirect taxes (VAT, entry tax, luxury tax, CST, purchase tax, etc.) when GST was introduced on 1 July 2017. To secure their consent, the Centre guaranteed that if a state's GST revenue grew below 14% per annum (compounded, using 2015-16 state revenue as the base), the Centre would make up the difference from the Compensation Cess pool. During COVID-19, cess collections fell sharply while protected revenue continued growing at 14%, creating a massive gap. The Centre borrowed Rs. 1.1 lakh crore in FY 2020-21 and Rs. 1.59 lakh crore in FY 2021-22 as back-to-back loans to states to cover the shortfall. The five-year compensation period ended in June 2022, but the cess levy was extended to March 2026 to service these borrowings. After 31 March 2026, the Compensation Cess is expected to end — the GST Council must decide whether to absorb it into the basic GST rate, levy it as a separate cess (e.g., health or clean energy cess), or discontinue it entirely. This is a critical fiscal federalism issue — states that depended on compensation payments now face the challenge of standing on their own GST revenue collections.
- UPSC Relevance: GS3 Economy — Prelims: 14% compounded annual growth guarantee, base year 2015-16, original 5-year period (July 2017 to June 2022), cess extended to March 2026 to repay COVID borrowings, cess levied on luxury and demerit goods (tobacco, aerated drinks, coal, motor vehicles, pan masala), Centre borrowed Rs. 2.69 lakh crore on behalf of states during COVID; Mains: was the 14% growth guarantee realistic (most states never achieved 14% own-revenue growth even before GST), impact of COVID on GST revenue and the compensation mechanism, post-March 2026 fiscal challenges for states (especially revenue-deficit states like Punjab, Kerala), should states have demanded a higher compensation period or a different formula, compensation cess as a case study in Centre-State fiscal relations and cooperative federalism.

GST Reforms 2024–25
Revenue Milestone
GST collections reached an all-time high of Rs. 2.10 lakh crore in April 2024 — a 12.4% year-on-year increase, driven by 13.4% growth in domestic transactions and 8.3% growth in import-related GST. Net GST revenue (after refunds) was Rs. 1.92 lakh crore, up 15.5%.
| Month | Gross GST Collection | Growth (YoY) |
|---|---|---|
| April 2024 | Rs. 2.10 lakh crore (record high as of date) | +12.4% |
| FY 2024-25 full year | Crossed Rs. 20 lakh crore (annual gross) | New annual milestone |
The April 2024 breakdown: CGST Rs. 43,846 crore, SGST Rs. 53,538 crore, IGST Rs. 99,623 crore (including Rs. 37,826 crore on imports), Compensation Cess Rs. 13,260 crore.
Rate Rationalisation — GoM Recommendations
The Group of Ministers (GoM) on GST Rate Rationalisation, chaired by Bihar Deputy Chief Minister Samrat Chaudhary, examined rate changes across 100+ items through 2024:
- The GoM considered phasing out the 12% slab by migrating items to either 5% or 18%, consolidating GST into a cleaner three-tier structure of 5%, 18%, and 28%
- Some proposals backed elimination of the 12% slab entirely — items currently at 12% would move to 5% (consumer goods) or 18% (standard goods)
- Broader discussion also included reducing the 28% slab to 18% for many currently demerit-categorised goods
- Implementation timeline and final consensus remained pending GST Council approval as of end 2024
GST 2.0 (56th GST Council, September 2025) subsequently enacted major simplification — reducing the four-slab structure to effectively three rates (0%, 5%, 18%, 40%), as detailed in the rate structure section above.
GST Appellate Tribunal (GSTAT)
| Feature | Detail |
|---|---|
| Constituted | President of GSTAT (retired Justice Sanjaya Kumar Mishra) appointed May 2024 |
| Structure | Principal Bench in New Delhi + 31 State Benches across 45 locations |
| E-Courts Portal | Online filing, case tracking, and digital hearings — developed by GSTN and NIC |
| Procedure Rules | GST Appellate Tribunal (Procedure) Rules, 2025 notified April 2025 |
| Significance | Resolves the long-standing gap in GST dispute resolution — taxpayers previously had no forum between Commissioner (Appeals) and High Court, causing litigation backlog |
The establishment of GSTAT addresses one of the biggest structural weaknesses in GST implementation since 2017 — an estimated 14,000+ pending GST appeals had no dedicated appellate forum.
Insurance GST — Ongoing Debate
A major 2024 debate centred on GST on health and term life insurance premiums, currently taxed at 18%:
- Opposition parties and consumer groups argued 18% GST on health and life insurance is regressive — it discourages insurance penetration in a country with low insurance coverage
- The GoM on Insurance GST Reduction (chaired by Bihar Deputy CM) considered reducing GST on term life insurance to 0% and on senior citizen health insurance to 0% or 5%
- Full implementation remained under GST Council deliberation through 2024-25
India's insurance penetration is approximately 4% of GDP — among the lowest for its development level — partly attributed to the high GST burden on premiums.
E-invoicing Threshold Reduction
Mandatory GST e-invoicing (B2B) was progressively extended to smaller businesses:
| Phase | Threshold | Effective Date |
|---|---|---|
| Phase 1 | Rs. 500 crore turnover | October 2020 |
