Since India's Goods and Services Tax (GST) regime came into effect in 2017, every taxable supply of goods or services within the country attracts one or more of three tax components: CGST, SGST, and IGST. Among these, CGST (Central Goods and Services Tax) is the portion the Central Government collects on intra-state transactions.
This article explains what CGST is, how it is calculated, how it differs from SGST and IGST, the legal framework that governs it, and the key compliance obligations for businesses.
Key Takeaways
- CGST applies exclusively to intra-state supplies where the buyer and supplier are located in the same state, levied alongside an equal SGST component.
- For inter-state transactions, CGST and SGST do not apply, and IGST is charged instead at a rate equal to the combined CGST and SGST percentages.
- The Central Goods and Services Tax Act, 2017, governs CGST, and the Central Board of Indirect Taxes and Customs (CBIC) administers it.
- Input Tax Credit (ITC) accumulated on CGST can be utilised to settle CGST or IGST liabilities, but cannot be offset against SGST liabilities.
- Businesses crossing aggregate turnover thresholds of ₹40 lakhs for goods (₹20 lakhs for services in most states) must mandatorily register under GST and collect CGST.
What Does CGST Mean?
Central Goods and Services Tax (CGST) is an indirect tax levied by the Central Government of India on intra-state supplies of goods and services under the Goods and Services Tax (GST) regime.
When a transaction occurs entirely within a single state, the tax liability is split equally between the central and state governments:
- CGST: Collected by the Central Government.
- SGST (State GST) / UTGST: Collected by the respective State or Union Territory Government.
For example, if you purchase a good or service within Mumbai with a total GST rate of 18%, the tax is divided evenly: 9% CGST goes to the central exchequer, and 9% SGST goes to the state government.
CGST replaces legacy central taxes such as Central Excise Duty, Service Tax, and additional customs duties, streamlining indirect taxation nationwide.
Importance of CGST
- Creates a Unified Tax Structure: GST consolidated multiple central and state indirect taxes into a single, cohesive framework. CGST serves as the vital Central Government component collected on intra-state supplies.
- Reduces the Cascading Effect (Tax-on-Tax): The integrated Input Tax Credit (ITC) mechanism allows businesses to offset eligible taxes paid on raw materials and business inputs against their output tax liabilities, eliminating cumulative tax burdens.
- Improves Tax Transparency: Standardised GST invoices mandate separate itemisation of tax components (CGST, SGST, or IGST), ensuring clarity for consumers and regulatory bodies on the exact tax collected.
- Supports Central Government Revenue: CGST directly contributes to the Central Government's fiscal pool from intra-state commerce, funding public infrastructure and national expenditure.
CGST, SGST, and IGST: The Differences
| Component | Full Form | Applies To | Collected By |
| CGST | Central GST | Intra-state supply | Central Government |
| SGST | State GST | Intra-state supply | State Government |
| IGST | Integrated GST | Inter-state supply (and imports) | Central Government (apportioned to states) |
How is CGST Calculated?
For an intra-state transaction:
CGST = Taxable Value × (GST Rate ÷ 2)
SGST = Taxable Value × (GST Rate ÷ 2)
For an inter-state transaction:
IGST = Taxable Value × GST Rate
Example
| Parameter | Intra-State Sale | Inter-State Sale |
| Taxable Value | ₹1,00,000 | ₹1,00,000 |
| Applicable GST Rate | 18% | 18% |
| CGST (9%) | ₹9,000 | — |
| SGST (9%) | ₹9,000 | — |
| IGST (18%) | — | ₹18,000 |
| Total Tax Payable | ₹18,000 | ₹18,000 |
GST Rate Table: CGST–SGST Split and Industry Examples
Under the revised GST structure introduced from 22 September 2025, the headline total GST rates are 0% (nil), 5% (merit rate), 18% (standard rate), and 40% (special demerit rate for selected supplies). On intra-state supplies, the applicable total GST rate is split 50:50 between CGST and SGST, with both components applied to the same taxable value. At 0%, neither component is payable.
| Total GST Rate Slab | Corresponding CGST Rate (Central Share) | Corresponding SGST Rate (State Share) | Industry Examples |
| 0% (Nil / exempt) | 0% | 0% | Food and dairy: UHT milk and pre-packaged and labelled paneer. |
| 5% (Merit rate) | 2.5% | 2.5% | FMCG: toilet soap bars, shampoos and toothpaste. |
| 18% (Standard rate) | 9% | 9% | IT services: domestic software development and IT consulting; consumer durables: air conditioners and televisions. |
| 40% (Special demerit rate) | 20% | 20% | Selected luxury goods: specified large and luxury cars, subject to vehicle classification. |
Note: Industry examples are illustrative, not sector-wide rate assignments. This table summarises the headline rates, not every notified rate; special rates remain applicable to specified goods, including precious metals and stones. Verify the relevant HSN/SAC classification, exemptions, conditions, and latest notifications before invoicing. Nil-rated and exempt supplies are distinct legal categories, although neither attracts output GST. UTGST replaces SGST where applicable in Union Territories; inter-state supplies attract IGST at the applicable total rate instead of separate CGST and SGST.
Input Tax Credit (ITC) Set-Off Rules for CGST
| ITC Available From | Can Be Set Off Against |
| CGST | CGST liability first, then IGST liability |
| SGST | SGST liability first, then IGST liability |
| IGST | IGST liability first, then CGST, then SGST |
Note: CGST credit cannot be used to pay SGST liability, and vice versa. This cross-utilisation restriction is a key compliance point for businesses reconciling their GST filings.
What is CGST Input Tax Credit?
Input Tax Credit (ITC) is a core mechanism of the GST framework that prevents the cumulative cascading of taxes ("tax on tax") through the supply chain.
A registered business can claim credit for eligible CGST paid on business purchases, provided the goods or services are used in the course of business.
Accumulated CGST credit can be utilised first against CGST output liability, and any remaining balance can then be set off against IGST liability.
To successfully claim ITC, the business must possess a valid tax invoice, ensure the supplier has paid the tax to the government, and file the mandatory returns.
Is CGST Charged on Every GST Transaction?
No. CGST is specific to certain transaction types and classifications:
- Intra-State Supplies Only: CGST applies only when both the buyer and the seller are in the same state (paired with an equal SGST component).
- Inter-State Transactions: For supplies crossing state borders or involving imports, Integrated GST (IGST) is charged instead of separate CGST and SGST.
- Exempt and Nil-Rated Supplies: Certain essential goods and services are designated as exempt, nil-rated, or non-taxable, meaning no CGST or other GST components are levied.
Businesses must carefully verify supply classification and place-of-supply rules before raising invoices or computing monthly tax liabilities.
Features of CGST
- Intra-State Applicability: CGST is levied exclusively on transactions where both the supplier and the consumer are located within the same state or union territory.
- Dual Tax Structure Alignment: It is charged concurrently alongside an identical SGST (or UTGST) rate on the exact same taxable transaction value.
- Central Revenue Pool: CGST collections go directly to the Central Government’s treasury to fund central public expenditures and economic initiatives.
- Statutory Governance: The Central Goods and Services Tax (CGST) Act, 2017, strictly regulates it, and the Central Board of Indirect Taxes and Customs (CBIC) oversees it nationally.
- Input Tax Credit (ITC) Mechanism: Businesses can claim CGST paid on raw materials and operational purchases as an offset against future CGST or IGST liabilities, preventing cascading tax burdens (“tax-on-tax”).
CGST Guidelines You Must Know
The Central Goods and Services Tax Act, 2017, governs CGST, and the Central Board of Indirect Taxes and Customs (CBIC) administers it under the overall policy direction of the GST Council.
This is a tax matter, not a securities market matter.
SEBI has no regulatory role in CGST, SGST, or IGST. Businesses dealing with GST compliance, registration, returns (GSTR-1, GSTR-3B, etc.), and audits interact with GST authorities and the GST portal, not SEBI.
Tax and Compliance Notes
- CGST is charged on the taxable value of a supply, which is the transaction value, subject to adjustments under GST valuation rules.
- Registered businesses must report CGST, SGST, and IGST separately in monthly/quarterly returns (GSTR-1 and GSTR-3B).
- CGST paid on eligible business purchases can be claimed as Input Tax Credit, reducing net tax liability, subject to conditions under Section 16 of the CGST Act.
- Certain goods and services are exempt or attract a nil rate, in which case no CGST/SGST/IGST applies.
- Composition scheme taxpayers pay tax at a lower fixed rate and cannot claim ITC.
Conclusion
CGST is one half of the tax charged on every intra-state supply under India’s GST system, working alongside SGST to ensure both the Central and State governments receive their share of indirect tax revenue. Understanding how CGST is calculated, how it interacts with SGST and IGST, and how Input Tax Credit set-off rules work is essential for accurate invoicing, return filing, and tax planning.
