CGST - Central Goods and Services Tax

What is CGST? Understanding the Basics

The CGST full form stands for Central Goods and Services Tax. Introduced under the CGST Act 2017, it is a fundamental component of India’s Goods and Services Tax (GST) structure. CGST is levied by the Central Government on intrastate supplies of goods and services, ensuring uniform taxation across the country.

Before the implementation of GST, businesses had to comply with multiple indirect taxes such as Excise Duty, Service Tax, and Central Sales Tax. With CGST applicability, businesses now follow a simplified tax structure, ensuring better compliance and easier tax administration.
 

CGST vs SGST: The Key Difference

A common confusion that businesses face is understanding the difference between CGST and SGST. Here’s how they differ from each other on various parameters,

• Central Goods and Services Tax: It is collected by the Central Government on intra-state transactions.
• State Goods and Services Tax: It is collected by the State Government on transactions.
• Both CGST and SGST in intrastate transactions are applied equally.

This mechanism ensures that tax revenue is shared between the Central and State Governments while maintaining uniform taxation.
 

CGST Tax Rate and Its Applicability

The tax rate varies for CGST depending on the type of goods and services. GST is structured into multiple CGST slab rates, ensuring a fair taxation system. The major CGST slab rates include,

• 5% – Essential goods and services (e.g., edible oil, milk powder)
• 12% – Standard goods and services (e.g., processed food, apparel)
• 18% – Majority of goods and services (e.g., electronic gadgets, IT services)
• 28% – Luxury goods and sin products (e.g., automobiles, tobacco)

Some essential goods and services fall under the CGST exemption list, ensuring affordability and accessibility for consumers. Items like unprocessed food, healthcare services, and educational services are typically exempt from CGST.
 

CGST Exemptions and Threshold Limits

Businesses must determine their CGST applicability based on their annual turnover,

• ₹40 lakh for suppliers of goods
• ₹20 lakh for service providers
• ₹10 lakh for businesses operating in some of the special category states

If a business does not exceed these limits, it is not required to register under the CGST registration process.
 

CGST Applicability and Registration Process

Businesses must comply with CGST rules and regulations to avoid legal complications. If your annual turnover exceeds the prescribed limits, you must complete the CGST registration process on the official GST portal.

Steps to Register for CGST:

• Filing an online application on the GST portal.
• Providing business details, including PAN, address, and business type.
• Uploading required documents, such as identity proof and business registration certificates.
• Verification by tax authorities through Aadhaar authentication or physical verification.
• Issuance of GSTIN (GST Identification Number) for tax compliance.

Failure to register under CGST applicability in India when required can lead to penalties, late fees, and legal consequences. Ensuring compliance helps businesses claim CGST input tax credit and operate seamlessly under the GST framework.
 

How is CGST Calculated?

The CGST calculation formula is straightforward:
CGST = (Taxable Value of Goods or Services) × (CGST Rate)
 

Example of CGST & SGST Calculation

If a company sells goods worth ₹10,000 with an 18% GST rate (9% CGST + 9% SGST), the CGST amount would be:

• CGST Amount: ₹10,000 × 9% = ₹900
• SGST Amount: ₹10,000 × 9% = ₹900
• Total GST Payable: ₹1,800 (₹900 CGST + ₹900 SGST)

Note: Here, percentages for tax calculation are taken just as an example to illustrate how it is exactly calculated.
Proper tax calculation ensures compliance with CGST rules and regulations, helping businesses avoid penalties and legal issues.
 

CGST Invoice Format: Compliance Matters

Every registered business must issue a GST compliant invoice that includes essential details to ensure tax transparency and accurate input tax credit claims. The required elements of a CGST invoice format include,

• The GSTIN (Goods and Services Tax Identification Number) of the supplier and buyer
• Unique invoice number and date
• Taxable value of goods or services
• GST breakup (CGST, SGST/IGST)
• Harmonized System of Nomenclature or Service Accounting Code
• Place of supply

Ensuring that invoices meet CGST rules and regulations is critical for compliance, smooth tax filing, and avoiding penalties.
 

CGST Refund Process: How to Claim It?

Businesses may be eligible for a CGST refund if they have excess tax credit due to input tax exceeding output tax. The process to claim a CGST refund involves the following steps:

• Filing GST refund application (Form RFD-01) on the GST portal.
• Providing necessary supporting documents, such as tax invoices, payment proofs, and statements of excess input tax credit.
• Verification and approval by the GST authorities, who may request additional details or reject the claim if discrepancies are found.
• The refund will be credited to the business bank account upon approval.
• Refunds are typically applicable in cases such as exports, inverted duty structure, excess cash balance, or final closure of business.

Businesses must ensure proper documentation to avoid delays or rejections.
 

CGST Late Fee and Penalty: Consequences of Non-Compliance

If businesses fail to comply with CGST rules and regulations, they are subject to penalties:

• Late fee for delayed GST return filing: ₹25 per day (CGST) + ₹25 (SGST), subject to a maximum cap.
• Late fee for nil returns: ₹10 per day (CGST) + ₹10 (SGST).
• Penalty for tax evasion: Up to 100% of the tax due. In cases of fraud, penalties can be higher, and prosecution may apply.

To avoid penalties, businesses should file GST returns on time, maintain accurate records, and ensure correct tax calculations.
 

CGST for Small Businesses: Are You Eligible for Exemptions?

Small businesses can benefit from the Composition Scheme, which allows them to pay GST at a lower rate with reduced compliance requirements. The scheme applies to businesses with a turnover below the prescribed limit,

• ₹1.5 crore for manufacturers and traders
• ₹50 lakh for service providers

Under this scheme:

• Manufacturers & traders pay 1% GST (0.5% CGST + 0.5% SGST).
• Restaurants pay 5% GST (2.5% CGST + 2.5% SGST).
• Service providers pay 6% GST (3% CGST + 3% SGST).

Businesses under this scheme cannot engage in interstate sales, supply goods through e-commerce platforms, or claim input tax credit (ITC). Choosing the Composition Scheme helps small businesses reduce tax burdens and simplify compliance.
 

CGST vs IGST: What’s the Difference?

Understanding the difference between CGST and IGST is crucial for businesses operating across multiple states in India.

• CGST (Central Goods and Services Tax) applies to intra-state transactions, where goods and services are supplied within the same state. It is levied along with SGST (State Goods and Services Tax), with both taxes being equally divided between the Central and State Governments.
• IGST (Integrated Goods and Services Tax) is charged on interstate transactions, i.e., when goods and services are supplied from one state to another. The Central Government collects IGST, which is later distributed to the destination state.
   

Example of CGST vs IGST Calculation

Let’s say a business in Maharashtra sells goods worth ₹50,000:

To a customer within Maharashtra (Intra-state transaction):

• CGST @ 9%: ₹4,500
• SGST @ 9%: ₹4,500
• Total GST Payable: ₹9,000

To a customer in Karnataka (Interstate transaction):

• IGST @ 18%: ₹9,000
• Total GST Payable: ₹9,000

Note: Here, percentages for tax calculation are taken just as an example to illustrate how it is exactly calculated.
Businesses must ensure proper CGST and IGST compliance to avoid penalties and incorrect tax filings.
 

CGST for Service Providers: Understanding the Tax Implications

The CGST applicability for service providers follows the same principles as goods. Any service provider earning above the GST registration threshold limit must register for GST and charge CGST on goods and services supplied within the state.

CGST Compliance for Service-Based Businesses

GST Registration:

• Service providers with an annual turnover exceeding ₹20 lakh (₹10 lakh for special category states) must register for GST.
• Freelancers, consultants, IT service providers, and agencies fall under this category.

Tax Rate on Services:

• Services are taxed based on the CGST slab rates, with most services falling under the 18% GST bracket.

CGST Invoice Format for Service Providers:

• Supplier and recipient details (GSTIN, name, address).
• Invoice number and issue date.
• Breakdown of CGST and SGST (for intra-state services).
• HSN/SAC code for service classification.

CGST Input Tax Credit (ITC) for Service Providers:

• ITC can be claimed on GST paid on business expenses, such as rent, software purchases, and marketing services.
• ITC cannot be claimed on blocked credits (e.g., personal expenses, motor vehicles, and employee benefits).
• Invoices must match in GSTR-2B to be eligible for ITC claims.

Failure to comply with CGST rules and regulations can lead to penalties and disruption in business operations.
