Constitutional Framework
GST required a constitutional amendment because taxation power over goods and services was divided between Centre and States. The 101st Constitutional Amendment Act 2016 created the framework. Article 246A: Both Parliament and State Legislatures have concurrent power to legislate on GST — departing from the earlier scheme where goods taxation was predominantly state (sales tax/VAT) and services exclusively central (service tax). Article 269A: GST on inter-state supply (IGST) is levied and collected by the Centre but apportioned to states based on the consumption principle. Article 279A: GST Council — a constitutional body (not statutory) consisting of Union FM (Chairman), Union MoS Revenue, and State Finance/Taxation Ministers. Decisions by 3/4th majority — Centre has 1/3rd voting weight, States collectively 2/3rd. No state can veto, but decisions are made by consensus in practice. 55+ meetings since formation. Article 286: Restrictions on taxation of interstate sale/purchase — amended for GST. Article 366 (12A): Defines GST as any tax on supply of goods or services except alcoholic liquor for human consumption. Items outside GST: Alcohol for human consumption (state excise), petroleum products (petrol, diesel, natural gas, ATF, crude oil — to be brought under GST when Council recommends), electricity (state duty), real estate (stamp duty). Tobacco is under GST plus additional excise/cess.
Dual GST Structure — CGST, SGST, IGST
India adopted a dual GST model (unlike single GST in Singapore, New Zealand). CGST (Central GST): Centre levies on intra-state supplies; revenue goes to Centre. SGST (State GST): State levies on intra-state supplies; revenue goes to the respective state. For UTs without legislatures (Chandigarh, Ladakh, Dadra & Nagar Haveli): UTGST replaces SGST. IGST (Integrated GST): Centre levies on inter-state supplies and imports. IGST = CGST + SGST rate. For inter-state B2B, the seller's state collects IGST which is apportioned — CGST to Centre, SGST to consumer state. This ensures destination-based taxation: revenue accrues where goods/services are consumed, not produced. Example at 18% rate: intra-state supply attracts 9% CGST + 9% SGST; inter-state supply attracts 18% IGST. The IGST model eliminated the complexities of CST and ensures seamless ITC across state borders. GST Compensation Cess: Levied on luxury and sin goods (SUVs, tobacco, aerated drinks, coal) to compensate states for revenue loss during the 5-year transition (2017-2022). The compensation period ended June 2022, but cess continues to repay Rs 2.69 lakh crore in borrowings made on behalf of states during COVID. Cess continues until March 2026.
Tax Slabs & Rate Structure
GST has 4 main slabs. 5%: Essential goods — food grains (branded/packaged), sugar, tea, edible oils, spices, basic clothing (below Rs 1,000), footwear (below Rs 1,000), coal, fertilisers, economy hotels, transport, small restaurants. 12%: Standard goods/services — processed food, computers, mobile phones, frozen meat/fish, business class hotels, restaurant services (non-AC with ITC). 18%: Most goods and services — capital goods, industrial inputs, IT services, financial services, telecom, restaurants (with ITC), FMCG (soap, toothpaste). Revenue-maximising slab with highest collections. 28%: Luxury and sin goods — automobiles (plus cess), cement, white goods (AC, washing machine, fridge), tobacco, aerated drinks, luxury hotels (>Rs 7,500/night). Exempt (0%): Unbranded food grains, fresh fruits/vegetables, milk, eggs, curd, bread, fresh meat/fish, healthcare, education, books, sanitary napkins (exempted 2018). Special: Gold 3%. Rough diamonds 0.25%. Revenue-neutral rate was estimated at 15-15.5%, but the weighted average has fallen from 14.4% (2017) to ~11.6% (2024) due to rate cuts and reclassifications. Rate rationalisation: 15th FC and economists recommend merging 12% and 18% into 15-16% — politically delayed due to resistance to rate increases on items currently at 12%.
Input Tax Credit (ITC) Mechanism
ITC is GST's backbone — it eliminates cascading (tax-on-tax) that plagued the pre-GST system where excise was not set off against state VAT. How it works: A manufacturer paying GST on inputs sets it off against GST collected on outputs. Only value addition at each stage is effectively taxed. Example: Input purchase Rs 100 + 18% = Rs 18 (input tax). Output sale Rs 200 + 18% = Rs 36 (output tax). Tax payable: Rs 36 - Rs 18 = Rs 18 (on Rs 100 value addition). ITC chain: CGST offsets CGST, SGST offsets SGST. IGST can offset IGST, then CGST, then SGST (cross-utilisation allowed). CGST cannot offset SGST or vice versa. Blocked credits (Section 17(5)): No ITC on motor vehicles (exceptions for supply/transport/training), food/beverages/health (except employer obligation), club/fitness membership, works contract for immovable property, rent-a-cab (with exceptions), life/health insurance (with exceptions). ITC fraud is a major challenge: fake invoicing through shell companies claiming fraudulent ITC. GST authorities detected Rs 1.14 lakh crore in fake ITC in FY24. Counter-measures: Invoice Matching System (IMS), mandatory e-invoicing (turnover above Rs 5 crore from August 2023), Aadhaar authentication for registration, physical verification, GSTN data analytics.
GSTN, Returns & Compliance
GSTN is the IT backbone — a 100% government-owned (Centre 50%, states 50%) not-for-profit managing gst.gov.in. Processes: registration, return filing, tax payment, refund, ITC matching, e-invoicing, e-way bills. Registrants: 1.46 crore (December 2024), up from 1.03 crore at launch. Returns: GSTR-1 (outward supplies — monthly by 11th), GSTR-3B (summary return with payment — monthly by 20th). GSTR-2B (auto-generated ITC statement from suppliers' GSTR-1). The original complex matching system (GSTR-1/2/3) was abandoned as unworkable — simplified to GSTR-1 + GSTR-3B. Composition Scheme: For turnover up to Rs 1.5 crore (Rs 75 lakh for services). Flat rate: 1% manufacturers, 5% restaurants, 6% other services. No ITC. Quarterly returns. ~17 lakh opted (FY24). E-way Bill: Required for goods movement above Rs 50,000. Generated on ewaybill.nic.in. ~10 crore bills/month (2024). E-invoicing: Mandatory for turnover above Rs 5 crore. IRP generates unique IRN and QR code — significantly improved compliance and reduced fake invoicing. Annual: GSTR-9 (return), GSTR-9C (reconciliation for turnover above Rs 5 crore). Filing compliance improved from ~60% (2017-18) to ~85% (2023-24).
GST Revenue Trends & State Compensation
GST revenue trajectory: FY18 (9 months) Rs 7.41 lakh crore. FY19 Rs 11.77 lakh crore. FY20 Rs 12.22 lakh crore. FY21 Rs 11.37 lakh crore (COVID — monthly low of Rs 32,172 crore in April 2020). FY22 Rs 14.83 lakh crore. FY23 Rs 18.10 lakh crore. FY24 Rs 20.18 lakh crore (crossed Rs 20 lakh crore for first time). FY25 estimated Rs 22+ lakh crore (average Rs 1.82 lakh crore/month). Highest month: April 2024 — Rs 2.10 lakh crore. Compensation: The GST (Compensation to States) Act 2017 guaranteed 14% annual revenue growth over FY16 base for 5 years (2017-2022). Shortfall compensated from Cess fund. During COVID (FY21-22), actual shortfall reached Rs 2.69 lakh crore. GoI borrowed on behalf of states and passed funds. Borrowings repaid from continuing cess (until March 2026). Post-compensation: Some states (Punjab, HP, Uttarakhand) face revenue stress; others (Gujarat, Maharashtra, Karnataka) show strong buoyancy. Revenue buoyancy exceeds 1 in FY23-25 — revenue grows faster than GDP, indicating broadening base, better compliance, and reduced evasion. Return-filing taxpayers grew from 72 lakh (FY18) to 1.13 crore (FY24). Key drivers: e-invoicing, AI-based mismatch detection, economic formalisation, and GDP growth.
GST Council — Key Decisions & Disputes
The GST Council (Article 279A) decides all GST matters — rates, exemptions, thresholds, model laws. Chaired by Union FM. Key decisions: 50th meeting (July 2023) taxed online gaming, horse racing, casinos at 28% on full face value (industry wanted 18% on GGR only). 52nd meeting (October 2023) cut millets-based products from 18% to 5%. 53rd meeting (June 2024) clarified railway platform tickets are not GST-liable, reduced rates on consumer items. 54th meeting (September 2024) cut health/life insurance premiums for senior citizens (0% for coverage up to Rs 5 lakh), discussed rate rationalisation. Constitutional disputes: (1) New India Assurance (2022): Supreme Court ruled GST Council recommendations are not binding on Parliament or State Legislatures — they are recommendatory. This affirmed parliamentary sovereignty while acknowledging cooperative federalism. (2) Revenue distribution: Production-heavy states vs consumption-heavy states — IGST settlement creates disputes. (3) Compensation formula: States argued 14% growth guarantee was inadequate given rate reductions decided by Council. (4) Petroleum inclusion: States oppose bringing petroleum under GST because petroleum taxes constitute 25-35% of state revenue. Centre also benefits from central excise. Neither side has incentive despite constitutional mandate.
GST — Impact Assessment & Reforms Needed
Positive impacts: (1) Unified national market — eliminated inter-state check posts, reducing logistics time 20-30%. Truck utilisation improved from 60% to 75%. (2) Formalisation: GST registration linked to PAN forced informal businesses to register. (3) Reduced cascading: ITC chain eliminated tax-on-tax, lowering effective burden on many goods. (4) Consumer benefit: Many manufactured goods became cheaper through ITC. (5) Simpler compliance: Single registration (except multi-state), unified return, e-filing — simpler than 17 taxes. (6) Revenue buoyancy exceeding GDP growth in recent years. Reforms needed: (1) Rate rationalisation: 4-slab structure needs simplification — frequent slab shifts create uncertainty. (2) Petroleum inclusion: Would reduce prices, complete ITC chain. (3) Real estate: Under-construction property attracts GST (5% without ITC, 1% affordable) but stamp duty is separate — double taxation concern. (4) MSME compliance burden: Monthly returns are onerous despite quarterly option. (5) Fake invoicing: Rs 1.14 lakh crore detected in FY24 despite e-invoicing and analytics. (6) Interstate IGST settlement delays. (7) Compensation Cess: Originally 5 years, extended due to COVID borrowings — needs definite end date. GoM on rate rationalisation has been constituted multiple times but concrete action is delayed by political sensitivities.
Pre-GST Indirect Tax System — What GST Replaced
GST subsumed 17 central and state taxes and 13 cesses. Central taxes: (1) Central Excise (on manufacture — petroleum and tobacco continue under excise). (2) Service Tax (15% pre-GST). (3) Additional Customs Duty (CVD). (4) Special Additional Duty (SAD). (5) Central Sales Tax (on inter-state sales). (6) Excise under Medicinal and Toilet Preparations Act. State taxes: (1) State VAT. (2) Entry Tax. (3) Octroi (massive corruption and delays at municipal limits). (4) Purchase Tax. (5) Luxury Tax. (6) Entertainment Tax (except local body levy). (7) Advertisement taxes. (8) State cesses and surcharges. Pre-GST problems: (1) Cascading: Excise at 12.5% and VAT at 14.5% without cross-credit meant effective tax could exceed 27%. GST's ITC eliminates this. (2) No inter-state credit: A Gujarat manufacturer selling to Maharashtra could not offset Gujarat VAT — CST (2-4%) was non-creditable. This fragmented the national market. (3) Complexity: Different rates, rules, and administration across 29 states. (4) Octroi/Entry Tax: Trucks spent 20-30% of transit time at checkposts. GST abolished all inter-state barriers — e-way bills replaced physical checks. (5) Classification disputes: Whether a product was "goods" (excise + VAT) or "service" (service tax) — software, restaurant meals, works contracts generated endless litigation. GST taxes "supply," resolving the goods-vs-services distinction.
GST Anti-Profiteering & Consumer Protection
Section 171 of CGST Act mandates that any tax rate reduction or ITC benefit must be passed to consumers through commensurate price reduction. NAA (constituted 2017) investigated complaints, ordered price reductions, returned undue profit to consumers, and could impose penalties up to 10% of profiteered amount or cancel registration. NAA handled 500+ cases and ordered Rs 2,500+ crore returned. Major cases: HUL (soaps, shampoos), P&G (detergents), restaurant chains. NAA was replaced by CCI for anti-profiteering from December 2022. Consumer impact: Several products became cheaper due to ITC — FMCG, restaurant meals, IT hardware. Some services became costlier: banking/financial services (18% vs 15% service tax), insurance, telecom, professional services. Overall inflation impact: RBI estimated 20-30 basis points one-time in FY18 — modest. Long-term benefit comes from eliminated cascading reducing input costs. GST Suvidha Providers (GSPs): 52 GSTN-authorised IT companies helping businesses file returns and manage ITC. Market: Rs 5,000+ crore — a new compliance technology ecosystem.
International Comparison — India's GST vs World
GST/VAT operates in 174 countries. India's GST is unique in several respects. Dual model: Few countries have dual GST. Brazil (PIS/COFINS + ICMS) is closest but far more complex. Canada has federal GST + Provincial Sales Tax. Most countries (EU, Singapore, New Zealand, Australia) have single national VAT with revenue sharing. India's federal structure necessitated dual — states would not cede taxation power entirely. Multiple rates: India has 4 slabs (5%, 12%, 18%, 28%) plus exempt and special. Singapore: 9%. New Zealand: 15%. Australia: 10%. EU: varies by country (17-27%) but each has one standard rate + one reduced. Multiple rates create complexity, classification disputes, and compliance burden. The ideal GST has a single rate with minimal exemptions — India deviates significantly. GST Council as federal institution: Unique to India — no other country has a constitutional federal body jointly deciding rates and rules. The EU VAT Committee is advisory; Canadian GST is federally determined with provincial autonomy. India's Council is a genuine cooperative federalism innovation — but the Supreme Court's 2022 ruling (recommendations not binding) created constitutional ambiguity. Revenue Neutral Rate: Estimated at 15-15.5%. Weighted average has fallen to ~11.6% (2024) — India collects less than the RNR, explaining initial shortfalls and the compensation cess need.
Place of Supply Rules & Cross-Border Taxation
Place of supply rules determine whether a transaction is intra-state (CGST+SGST) or inter-state (IGST) — crucial for correct collection and revenue allocation. For goods: Intra-state if supplier location and supply place are in the same state. With movement: place of supply = delivery terminus. Without movement: location of goods at supply time. Imports: place of supply = importer location (always IGST). For services: General rule — place of supply = recipient location. Exceptions: (a) Immovable property — property location. (b) Restaurant/catering — performance location. (c) Training/events — event location. (d) Goods transport — recipient location. (e) Telecom — billing address. (f) Banking — recipient location. Export of services is zero-rated (0% GST but ITC available) — conditions: supplier in India, recipient outside, place of supply outside, payment in convertible forex. This supports India's IT/ITeS exports ($194 billion FY24). Import of services: Taxed under Reverse Charge — Indian recipient pays IGST. Relevant for cloud computing, SaaS, consulting from foreign providers. Zero-rated vs exempt: Zero-rated = 0% rate but ITC claimable on inputs (no tax cost in exports). Exempt = no GST and no ITC (tax cost embedded in price). This distinction was a major improvement — pre-GST exporters often accumulated blocked credits.
Reverse Charge Mechanism (RCM)
Under normal GST, the supplier collects and pays. Under RCM, the recipient pays directly to government. Three situations: (1) Notified goods/services: Import of services from non-resident (Section 5(3) IGST), GTA services, legal services by advocate, sponsorship, government/local authority services. (2) Supply by unregistered to registered: Registered person pays GST under RCM (Section 9(4) — modified to apply only to specified categories). (3) E-commerce operators: For specified services (transport, accommodation), operator pays under Section 9(5). From January 2022, Swiggy and Zomato collect and pay GST on restaurant services delivered through their platform. Key implications: RCM ensures compliance even when the supplier is small, unregistered, or abroad. It prevents revenue leakage in sectors with many informal suppliers. The recipient can claim ITC on RCM amounts paid (subject to normal conditions). Composition dealers cannot avail ITC on RCM — they bear the cost. Time of supply under RCM: Date of payment or 30 days from invoice (60 days for services), whichever is earlier.
GST on Digital & E-Commerce Economy
Special provisions for digital/e-commerce: (1) E-commerce operator: Any person owning/operating a digital platform for e-commerce (Amazon, Flipkart, Zomato, Swiggy, OYO, Ola, Uber). (2) TCS (Section 52): Operators collect 1% (0.5% CGST + 0.5% SGST) from net taxable supply value on their platform — tracks transactions and ensures seller compliance. (3) Mandatory registration: Platform sellers must register regardless of turnover (Rs 20/40 lakh threshold does not apply) — significant burden on small sellers. (4) Restaurant services: From January 2022, Swiggy and Zomato pay 5% GST on platform deliveries (treated as supplier) — earlier restaurant was supplier but small restaurant compliance was poor. (5) OIDAR (Online Information and Database Access or Retrieval): Automated internet services (Netflix, AWS, online gaming, advertising). Non-resident OIDAR providers to non-taxable Indian consumers must register and pay IGST. (6) Online gaming: 50th Council meeting (July 2023) imposed 28% on full face value of bets (not platform fee). Industry wanted 18% on GGR. Listed gaming stocks fell 40-50%. First quarter post-implementation (Oct-Dec 2023) generated Rs 5,200 crore — up from Rs 1,700 crore same quarter prior year, validating revenue expectations.
GST Litigation, Advance Ruling & Tribunal
GST has generated significant litigation from classification disputes, ITC claims, and interpretive ambiguities. Advance Ruling Authority (ARA): Each state has an ARA (one Centre + one State member) providing binding rulings on classification, rate, ITC, and place of supply. Problem: Different ARAs gave conflicting rulings on the same product — parota vs roti (5% vs 18%), ice cream parlour vs restaurant — contradicting "One Nation, One Tax." AAAR hears appeals but decisions bind only within the state. GSTAT (established 2023, Section 109): Principal Bench in Delhi, 31 state benches. Composition: President (retired/sitting HC judge) + one technical member (Centre) + one technical member (State). Hears appeals from Appellate/Revisional Authorities. Orders bind nationally — resolving the conflicting ruling problem. Commenced 2024. Over 14,000 cases were pending before High Courts and Supreme Court by 2024. Key SC rulings: (1) New India Assurance/Mohit Minerals (2022): Council recommendations are recommendatory, not binding — Article 246A gives independent legislative power to both Centre and States. (2) Ocean Freight: IGST on ocean freight for CIF imports struck down as double taxation (IGST on imported goods already includes freight value). Over Rs 3,500 crore refunded.
GST on Financial Services & Insurance
Financial services attract 18% GST — a contentious jump from 15% service tax. Banking: All charges (processing, maintenance, locker, card, transfer fees) at 18%. Loan interest is exempt. Penal charges are taxable. Insurance: Life and health premiums at 18%. 54th Council (September 2024) cut health insurance for senior citizens to 0% (policies up to Rs 5 lakh). Term insurance: 18% on premium adds Rs 1,800 on Rs 10,000 premium for Rs 1 crore cover. This has been politically contentious — high GST discourages penetration (India: 4% of GDP vs global 6.8%). ULIPs: 18% on risk premium and fund management charges. Stock market: Brokerage at 18%. Depository services at 18%. STT stays outside GST. Mutual fund management fee: 18% on AMC charges — embedded in expense ratio. A 1.5% expense ratio effectively becomes 1.77%. Credit/debit card: Annual fees, late charges, reward fees all at 18%. Forex: 18% on conversion margin. LRS remittances: 18% on bank service charges.
Impact on Agriculture & Food Processing
Exempt (0%): Fresh fruits/vegetables, fresh milk, eggs, fresh meat/fish, curd, lassi, buttermilk, bread, unbranded wheat/rice/atta/pulses, jaggery, natural honey, live animals. Principle: Unprocessed and unbranded agricultural products are generally exempt. 5%: Branded/packaged food grains (pre-packaged below 25 kg taxed at 5% from July 2022 — controversial), sugar, tea, edible oils, spices, milk products (flavoured/condensed), frozen meat/fish. Fertilisers at 5% (reduced from 12%). 12%: Processed food (butter, cheese, frozen vegetables, juices). 18%: Processed foods like instant noodles, chocolates. July 2022 controversy: 5% GST imposed on pre-packed labelled food items (rice, wheat, curd, buttermilk in packets up to 25 kg). Previously exempt regardless of packaging. Rationale: capture growing branded sector while keeping loose items exempt. Perceived as "tax on food." Food processing benefit: ITC availability reduces cascading (pre-GST, excise + VAT without cross-credit). Uniform tax across states eliminates inter-state friction. However, inverted duty structure (5% output but 12-18% inputs like packaging, machinery, fuel) creates ITC accumulation difficult to refund — squeezing food processor margins. This remains a major unresolved issue.
Inverted Duty Structure & Refund Issues
Inverted duty structure: Input GST rate exceeds output GST rate, creating accumulated ITC that cannot be offset. This leads to refund claims facing delays and working capital problems. Affected sectors: (1) Textiles: Fabrics 5%, yarn 12%. (2) Footwear: Shoes below Rs 1,000 at 5%, raw materials 12-18%. (3) Fertilisers: Output 5%, inputs 12-18%. (4) Food processing: Output 5%, packaging/machinery 18%. (5) Renewable energy: Solar modules 5% (pre-2022), steel/copper/glass 18%. (6) Pharma: Essential drugs 5%, APIs 12-18%. Refund formula: Maximum refund = (Turnover of inverted supply / Adjusted total turnover) x Net ITC minus Tax payable. This excludes input services from refund calculation — VKC Footsteps SC ruling (2021) clarified this, and government amended Rule 89(5) to exclude input services, further restricting refunds. Policy options: (a) Merge 5% and 12% into 8-9% — eliminates most inversions but raises essential goods prices. (b) Expand refund to include input services. (c) Reduce input rates for affected sectors. 15th FC and GoM on rationalisation both prioritised this. Pending ITC refund claims: Rs 25,000+ crore (FY24). Delays hit MSMEs hardest — they lack working capital to absorb locked-up ITC.
GST on Real Estate & Construction
Under-construction property attracts GST. Ready-to-move (with completion/occupancy certificate): Exempt (stamp duty applies). Rates (post-33rd Council, April 2019): Regular residential apartments 5% without ITC (earlier 12% with ITC). Affordable housing (up to Rs 45 lakh, carpet area 60 sqm metro / 90 sqm non-metro): 1% without ITC (earlier 8% with ITC). Commercial property: 12% with ITC (sold before completion). "Without ITC" means builders cannot claim credit on construction inputs (cement 28%, steel 18%, paints 18%) — entire input cost is embedded in price. Effective incidence estimated at 5-8% on builder margin after input costs. This was a compromise — Council reduced headline rate but removed ITC to prevent "gold-plating." Problems: (a) No ITC on land (outside GST — stamp duty). One-third of consideration is deemed land value and excluded. (b) Double taxation: Buyer pays GST on under-construction purchase AND stamp duty on registration. (c) Anti-profiteering: NAA penalised DLF, Tata Housing for not passing ITC benefits. (d) Works contract: 12-18% depending on government/private — significant for construction companies. Joint Development Agreements: GST applies on developer's supply of flats to landowner. Time of supply: completion certificate issuance.
State GST Revenue & Fiscal Impact
GST transformed sub-national fiscal architecture. Pre-GST, states relied on VAT (45-50% of own tax), entry tax, entertainment tax, luxury tax, CST — all subsumed. Post-GST states receive: SGST on intra-state transactions, IGST share (destination principle), divisible pool devolution (41% per 15th FC). Revenue gainers (consumption states): Kerala, Rajasthan, Bihar, Jharkhand, HP, Uttarakhand — destination-based taxation shifts revenue from production to consumption states. Revenue losers (production states): Gujarat, Maharashtra, TN, Karnataka — traditionally collected high VAT on manufacturing. Compensation mechanism: 14% annual growth over FY16 base guaranteed for 5 years. Formula: Protected revenue (base x 1.14^n) minus actual SGST + IGST settlement. Shortfall paid from cess fund — critical assurance that convinced states to agree. COVID impact: Centre provided Rs 1.1 lakh crore (FY21) and Rs 1.59 lakh crore (FY22) through back-to-back loans. Total borrowing: Rs 2.69 lakh crore — repaid from cess continuing beyond June 2022 until March 2026. Post-compensation (July 2022+): States no longer receive guaranteed growth. Strong-economy states show buoyancy above 1.2. Weaker states (Punjab, Goa, HP) face revenue stress. The end of compensation has renewed calls for extended support.
Relevant Exams
GST is one of the most heavily tested economics topics across all competitive exams. UPSC Prelims asks about GST constitutional provisions (Articles 246A, 269A, 279A), Council composition and voting weights, items outside GST (petroleum, alcohol), compensation cess, RCM, and anti-profiteering. SSC CGL tests GST launch date, slab rates, and basic concepts. IBPS PO asks about GSTN, e-way bills, and recent GST Council decisions. UPSC Mains GS Paper 3 has questions on GST impact, rate rationalisation, cooperative federalism dimensions, and inverted duty structure.
