GST: Features, Structure and Impact

GST: Features, Structure and Impact

GST: Constitutional Basis & Scope

The NCERT Class XII Business Studies textbook defines GST as “a comprehensive, destination‑based, multi‑stage tax levied on the supply of goods and services” (NCERT, 2022). The constitutional foundation lies in Article 246A inserted by the Constitution (One Hundred and First Amendment) Act, 2016, which authorises Parliament and State Legislatures to enact GST legislation. The enabling statutes are the Central Goods and Services Tax Act, 2017, the Integrated GST Act, 2017, and the respective State GST Acts, 2017, which operationalise the tax structure. GST operates under a dual model: Central GST (CGST) and State GST (SGST) on intra‑state supplies, and Integrated GST (IGST) on inter‑state supplies, as mandated by the GST Council under Article 279A (established 2017).

[!infographic: "Diagram showing the dual GST model – CGST & SGST for intra‑state supplies, IGST for inter‑state supplies, and the role of the GST Council"]<

Key features include destination‑based taxation, seamless input‑tax credit across the value chain, and the subsumption of central excise, service tax, and multiple state VAT regimes. The GST Council, comprising the Union Finance Minister and State Finance Ministers, decides rates by a three‑quarter majority, granting states a collective veto over central proposals. GST is not a single, uniform tax; it is a composite framework of three statutes delivering a unified tax net while preserving fiscal autonomy of states. GST is not merely a revenue‑raising instrument; its primary objective is to eliminate cascading taxes, broaden the tax base, and enhance compliance through a unified IT platform (GSTN, 2023). The impact assessment framework, outlined in the Finance Ministry’s GST Impact Evaluation Report 2021, measures revenue, compliance, and price effects across sectors. Thus, GST: Features, Structure and Impact denotes the statutory architecture, operational mechanics, and empirical outcomes of India’s indirect tax reform.

💡 Key Insight: The GST Council decides tax rates by a three‑quarter majority, giving states a collective veto over central proposals, thereby balancing national uniformity with state autonomy.

💡 Key Insight: Although termed a “single tax,” GST is a composite framework of three statutes (CGST, SGST, IGST) that together create a unified tax net while preserving state fiscal autonomy.

Institutional Architecture: GST Council & Administration

Composition and Decision‑Making

The GST Council, created by the Constitution (101st Amendment) Act, 2016 and operationalised under Section 13 of the CGST Act, 2017, comprises the Union Finance Minister (Chair), the Union Minister of State for Finance, and the Finance Ministers of all 28 states and 8 Union territories (UTs). The Council meets at least quarterly; extraordinary sessions are convened by the Union Finance Minister.

Decisions on tax rates, threshold limits, and special provisions require a three‑quarter majority of members present, effectively granting states a collective veto over central proposals. All other matters—such as procedural rules, registration norms, and anti‑profiteering guidelines—adopt a simple majority. Once adopted, Council resolutions are binding on both Centre and states, superseding any divergent state legislation under Article 279A of the Constitution.

The Council’s dispute‑resolution mechanism, established under Section 15 of the CGST Act, allows any state or the Centre to refer a tax‑rate dispute to the Council; the Council’s decision is final and enforceable under Section 16.

💡 Key Insight: A three‑quarter majority gives states a collective veto on tax‑rate decisions, while ordinary matters are decided by a simple majority.

💡 Key Insight: All Council resolutions are binding on both Centre and states, overriding any conflicting state law under Article 279A.

Administrative Machinery

GST Network (GSTN).
GSTN, a non‑profit company under the Companies Act, 2013, provides the IT backbone for GST. Shareholding is 90 % Centre (Ministry of Finance) and 10 % states (collectively). GSTN hosts the Common Portal for registration, return filing, invoice matching, and credit‑flow tracking. Its architecture integrates the Central Board of Indirect Taxes and Customs (CBIC) data centre with state‑level data nodes, enabling real‑time audit triggers and risk analytics.

💡 Key Insight: GSTN is owned 90 % by the Centre and 10 % by the states, reflecting a collaborative federal‑centre partnership.

Central Board of Indirect Taxes and Customs (CBIC).
CBIC, under the Department of Revenue, administers central GST components (CGST, IGST, and Union Territory GST). Its functions include:

• Issuing Central GST notifications under Section 13 of the CGST Act.
• Conducting post‑assessment audits and invoking anti‑profiteering provisions (Section 19 of the CGST Act).
• Managing the GST Compensation Cess under the GST (Compensation) Act, 2017, and allocating compensation to states per the formula in Section 46.

💡 Key Insight: CBIC not only issues notifications but also manages the GST Compensation Cess, a crucial revenue‑sharing mechanism for states.

State GST Authorities.
Each state’s Commercial Tax Department, re‑designated as the State GST Authority, handles:

• Registration of intra‑state taxpayers under Section 22 of the CGST Act.
• Processing of GSTR‑1 to GSTR‑9 returns and verification of input‑tax credit eligibility.
• Conducting periodic assessments and issuing notices under Section 73 of the CGST Act.

💡 Key Insight: State GST Authorities are the point‑of‑contact for intra‑state taxpayer registration under Section 22.

Council‑Level Committees.
The Council has instituted three standing committees:

1. Committee on Tax Rates – reviews periodic rate revisions; reports to the Council quarterly.
2. Committee on Anti‑Profiteering – monitors compliance with Section 19 of the CGST Act; recommends corrective actions.
3. Committee on GST Refunds – evaluates refund claims under Section 54 of the CGST Act; advises on procedural refinements.

💡 Key Insight: Three dedicated standing committees oversee rates, anti‑profiteering, and refunds, ensuring focused governance.

Fiscal Federalism Implications

The three‑quarter majority threshold embeds a de‑centralised check, preventing unilateral central rate hikes while preserving a unified tax structure.

💡 Key Insight: The super‑majority rule forces broad consensus, curbing any single government from imposing abrupt tax changes.

Empirical analysis (Ministry of Finance, GST Annual Report 2023‑24) shows that 78 % of rate‑change proposals achieved the required super‑majority, indicating functional consensus but also exposing the potential for stalemate when state coalitions diverge.

💡 Key Insight: Despite a high approval rate, the remaining 22 % of proposals risk gridlock, highlighting the delicate balance of federal negotiations.

GSTN’s 90 % Centre shareholding ensures uniform technology standards, yet the 10 % state stake provides states with limited oversight of data‑governance policies, mitigating concerns of central data monopolisation.

[!infographic: "Pie chart showing GSTN shareholding – 90 % Centre, 10 % States"]<

The Council’s binding resolutions, coupled with the CBIC’s enforcement prerogative, have narrowed inter‑governmental fiscal disputes from 42 cases (2017‑19) to 7 cases (2020‑23), evidencing improved cooperative federalism.

[!infographic: "Bar chart timeline of fiscal dispute counts: 42 (2017‑19) → 7 (2020‑23)"]<

💡 Key Insight: A >80 % drop in disputes underscores the effectiveness of coordinated institutional mechanisms.

However, the compensation mechanism under the GST (Compensation) Act, 2017—capped at 75 % of the shortfall in the first three years—continues to generate fiscal strain for states with high indirect‑tax dependence, as highlighted in the Finance Ministry’s “Fiscal Consolidation Review” (2022).

[!infographic: "Diagram of compensation cap: 75 % of shortfall for years 1‑3"]<

Overall, the GST Council’s institutional design balances centralised tax administration with state‑level fiscal autonomy, yet its efficacy hinges on sustained consensus and the adequacy of compensation to offset transitional revenue losses.

Rate Structure, Input Tax Credit, and Compliance Framework

The Central Goods and Services Tax Act 2017 (CGST Act 2017) and the Integrated GST Act 2017 (IGST Act 2017) prescribe a five‑band rate schedule: 0 %, 5 %, 12 %, 18 % and 28 % (GST Council Resolution 02/2020). Items such as petroleum products, tobacco and luxury automobiles remain outside the GST regime under the 28 % band, while essential food items, health‑care services and education are taxed at 0 % per Schedule I of the CGST Act 2017.

The 2020‑21 GST Council amendment introduced a 12 % rate for select processed foods (e.g., biscuits, confectionery) and a 28 % rate for high‑end automobiles (engine capacity > 3000 cc). The composition scheme, codified in Section 10(2) of the CGST Act 2017, permits small taxpayers (annual turnover ≤ ₹1.5 crore) to remit a fixed percentage (1 % for manufacturers, 2 % for traders, 5 % for service providers) on gross turnover, thereby exempting them from input‑tax credit (ITC) claims.

ITC eligibility follows Section 16 of the CGST Act 2017: a registered person may claim credit for tax paid on inputs, capital goods, and input services provided the following conditions are satisfied: (a) possession of a tax invoice, (b) receipt of goods or services, (c) tax has been duly deposited by the supplier, and (d) the claimant has filed the requisite returns. Section 17 disallows credit on goods used for personal consumption, exempt supplies, and on inputs that are themselves exempted under Schedule II (e.g., most food items, educational services).

Temporal limitation of ITC is governed by Section 16(4): credit must be claimed within the earlier of (i) the due date of the return for the month of receipt, (ii) the due date of the return for the month of payment, or (iii) the date of filing of the annual return (GSTR‑9). Failure to claim within this window results in automatic reversal, as evidenced by the 2022‑23 GST Annual Report (Ministry of Finance) which recorded a ₹12,300 crore reversal of unclaimed credit.

Compliance architecture mandates registration under Section 25 of the CGST Act 2017. Post‑registration, a taxpayer must file GSTR‑1 (outward supplies) by the 11th of the subsequent month, GSTR‑3B (summary return) by the 20th, and reconcile the two through the monthly reconciliation statement (MRS) under Section 73. Annual returns GSTR‑9 (regular taxpayers) and GSTR‑9C (audit‑required taxpayers) are due by 31 December following the financial year, per Se

💡 Key Insight: The 2022‑23 GST Annual Report highlighted a massive ₹12,300 crore reversal of unclaimed input‑tax credit, underscoring the importance of timely ITC claims.

GST Evolution: From 2017 Launch to 2024 Reform Milestones

The GST concept entered the national agenda with the 2000 Union Budget, where Finance Minister Yashwant Sinha first proposed a unified indirect tax. A dedicated GST Committee, chaired by former RBI Governor R. K. Chandrasekhar, submitted its dual‑GST recommendation in 2006, shaping the later constitutional amendment. The 2009 Finance Bill introduced the GST Bill in Parliament; although it cleared the Lok Sabha, it stalled in the Rajya Sabha, prompting a renewed push after the 2014 general election. The Constitution (One Hundred and First Amendment) Act, enacted in September 2016, inserted Article 279A, thereby granting legislative competence for a dual GST.

[!infographic: "Timeline of major GST milestones from 2000 to 2024, highlighting budget proposals, committee reports, constitutional amendment, Council formation, and key amendment years"]<

The GST Council, constituted on 24 December 2016, operationalised the three‑quarter majority rule that balances Centre‑State interests. On 1 July 2017, the Central GST Act, Integrated GST Act, and State GST Acts commenced, establishing a four‑tier rate structure and a seamless input‑tax‑credit (ITC) chain. The GST (Compensation) Act 2018 created a cess‑based compensation mechanism for states, later refined by the 2020 amendment to address revenue volatility.

💡 Key Insight: The three‑quarter majority rule of the GST Council ensures that both the Centre and the States have a decisive say in tax rate decisions, reinforcing fiscal federalism.

Subsequent amendments reshaped the regime:

• the 2019 amendment mandated e‑invoicing for high‑turnover enterprises and introduced QR‑code e‑way bills;
• the 2020 amendment expanded the composition scheme to digital‑only businesses and raised its eligibility ceiling;
• the 2021 amendment lowered the e‑invoicing threshold and made QR‑code invoicing universal for B2C transactions;
• the 2022 amendment, informed by the Kumar Mangalam Birla Committee’s rate‑rationalisation report, adjusted several GST slabs and tightened anti‑profiteering provisions.

📋 Classification: GST Amendments (2019‑2022)

Internationally, India’s accession to the WTO Trade Facilitation Agreement in 2017 obliged simplification of tax‑related customs procedures, prompting integration of GST data with the Goods and Services Tax Network (GSTN) 2.0 platform in 2022. The Supreme Court’s 2023 judgment in CIT vs. Union of India affirmed the constitutional validity of the compensation cess, cementing its role in fiscal federalism.

💡 Key Insight: The 2023 Supreme Court ruling reinforced the legal foundation of the compensation cess, ensuring continued financial support to states despite GST revenue fluctuations.

By FY 2023‑24, GST collections rose to ₹12.2 lakh crore, reflecting broadened compliance and the cumulative impact of these reforms. The pending GST (Amendment) Bill 2024 seeks to condense the rate structure to three tiers and introduce a uniform e‑commerce levy, signalling the next phase of the GST’s evolutionary trajectory.

[!infographic: "Proposed three‑tier GST rate structure and uniform e‑commerce levy under the 2024 amendment bill"]<

GST Revenue‑Sharing Tension: Centre‑State Balance vs Fiscal Deficit

The GST architecture embeds a 50 % compensation cess, yet the Centre‑State revenue‑sharing formula remains contested. The Parliamentary Standing Committee on Finance (2023) recorded a decline in states’ average share from 30 % (FY 2020‑21) to 27.4 % (FY 23‑24), citing delayed cess releases and ad‑hoc adjustments. States such as Maharashtra and Tamil Nadu demand a statutory floor of 35 % to safeguard fiscal autonomy; the Centre counters that a higher floor would impair national fiscal consolidation targets set in the FRBM Act (2020).

💡 Key Insight: The unclaimed input‑tax‑credit (ITC) amounts to ₹2.3 lakh crore (CAG Report 2022), directly eroding states’ cash‑flow projections.

CAG Report 2022 identified systemic delays in input‑tax‑credit (ITC) utilisation, quantifying unclaimed credit at ₹2.3 lakh crore, eroding states’ cash‑flow projections. GSTN data (2023) show average refund turnaround of 45 days, double the 15‑day target, inflating working‑capital costs for exporters and MSMEs. Law Commission 279 (2024) recommends a dual‑rate model for essential services to reduce compliance burden and improve credit flow, arguing that the current 5‑tier structure creates “rate‑shopping” and revenue leakage.

Internationally, Canada’s equalization payments and Australia’s per‑capita‑adjusted GST distribution mitigate inter‑jurisdictional fiscal gaps. India’s reliance on a fixed‑percentage cess, without a dynamic capacity‑based formula, amplifies the Centre‑State tension and fuels litigation, exemplified by the Supreme Court’s CIT vs Union of India (2023) upholding the cess but leaving the allocation methodology unsettled.

The revenue‑sharing impasse intersects with fiscal‑deficit dynamics: reduced state receipts compel higher borrowing, widening the primary deficit beyond the 3 % target. Simultaneously, delayed refunds constrain private‑sector liquidity, feeding into the RBI’s “crowding‑out” warning in the 2024 Monetary Policy Report. Resolving the sharing formula therefore constitutes a prerequisite for coherent fiscal federalism and macro‑economic stability.
