What is SGST? Full Form, Rates, Formula & CGST vs SGST Difference

Table of Contents

Any business transaction in India, whether it’s between sellers or seller to customer, it attracts GST. The Goods and Services Act 2017, which has today revolutionized India’s taxation system has taken India towards the One Nation One Tax system.

Within GST, there is SGST, CGST, and IGST. Our discussion today will be on SGST or State Goods and Services Tax. SGST is meant to replace the complex and varied state-level taxes to provide a unified and simplified tax structure.

Let’s dig deep into what is SGST, how it operates, SGST rates, the key sections of the SGST Act, and more.

What is SGST? Full Form and Meaning

SGST stands for State Goods and Services Tax and is levied by the state governments on the supply of goods and services happening within the state’s boundaries.

SGST applies to intrastate transactions meaning both the supplier and the buyer are located in the same state.

For example, if a business in Mumbai sells products to a customer in Pune, both being in Maharashtra, SGST is charged along with CGST (Central Goods and Services Tax).

SGST provides a dedicated revenue stream to the state governments, which they can use for various public welfare projects and essential services.

How Does SGST Works in India?

India has a tiered taxation system where GST sits at the top, then there is CGST, SGST, IGST, and UTGST.

This multi-level tax structure is meant to benefit the centre and the states as they now have the power to levy taxes on different goods and services. SGST is majorly applied on the transactions within a state.

But what about the interstate transactions? There IGST applies, and the tax is apportioned equally between the centre and the state. When a customer in Delhi buys a product from West Bengal, IGST applies. Suppose the goods are worth ₹10,000 and on these, there is an 18% GST.

This means the ₹1800 tax collected from this transaction is divided between the centre and the state where each receives ₹900.

When is SGST Applicable?

SGST applies to intrastate supplies, which means the location of the supplier and the place of supply are in the same state. For example, SGST applies when;

A restaurant in Bangalore billing a customer dining in Bangalore.
A Delhi-based software company providing services to a Delhi client.
A retailer in Jaipur selling furniture to a Jaipur resident.
An online marketplace facilitating a sale where both seller and buyer are in Kerala

Following this principle, it’s clear that SGST does not apply on interstate transactions.

Who Collects and Benefits from SGST?

The supplier collects SGST from the buyer at the point of sale and deposits it with the respective state government through the GST portal.

State governments utilize SGST revenue for:

Building and maintaining roads, bridges, and local infrastructure.
Funding public healthcare facilities and hospitals.
Supporting state education systems and schools.
Implementing welfare schemes and social programs.
Developing urban and rural infrastructure.

However, not all businesses need to charge SGST as the ones with an annual turnover of more than ₹40 lakhs can register for GST.

SGST Calculation Formula (With Examples)

The formula for calculating SGST is:

SGST Amount = (Taxable Value × SGST Rate) / 100

The taxable value is the transaction value of goods and services plus additional charges, including packaging, freight, insurance, and commissions.

Here are three examples showing three different scenarios for SGST calculation;

Example 1: Basic Calculation

A retailer in Chennai sells electronics worth ₹50,000 to a customer in Chennai. GST rate is 18% (9% CGST + 9% SGST).

Taxable Value: ₹50,000
SGST @ 9%: ₹50,000 × 9/100 = ₹4,500
CGST @ 9%: ₹4,500
Total GST: ₹9,000
Final Invoice Amount: ₹59,000

Example 2: Different GST Rate

A restaurant in Mumbai bills ₹2,000 for food (GST 5%: 2.5% CGST + 2.5% SGST).

SGST @ 2.5%: ₹2,000 × 2.5/100 = ₹50
CGST @ 2.5%: ₹50
Total Bill: ₹2,100

Example 3: Business Scenario with Additional Charges

A furniture manufacturer in Jaipur sells to a Jaipur dealer:

Base Value: ₹1,00,000
Packing Charges: ₹5,000
Transportation: ₹3,000
Taxable Value: ₹1,08,000
GST Rate: 12% (6% CGST + 6% SGST)
SGST @ 6%: ₹6,480
CGST @ 6%: ₹6,480

Key Features of State Goods and Services Tax (SGST)

The introduction of SGST is meant to streamline how transactions are taxed, how these taxes are collected, and how they are reported.

Simplified Tax Structure: SGST replaces multiple state-level taxes like VAT, entertainment tax, luxury tax, entry tax, and more. By consolidating them into a single tax, GST has eliminated the complexity of dealing with different tax regimes.
Uniform Tax Rates: SGST ensures every state has a consistent tax rate for the same goods and services. This makes for a transparent system offering ease of compliance for businesses and for states it’s easier to manage and consolidate taxes.
Destination-Based Taxation: SGST is a destination-based tax, which means tax revenue flows to the state where goods or services are consumer and not where they are produced. With this, the consuming states benefit from the economic activity within the borders.
State-Specific Legislation: Every state has its own SGST Act, which means while maintaining uniformity in the taxes, valuation methods, and taxable events. But it also means the states can make certain changes as per their economic needs and current situation; however, these changes must align with the decisions of the GST Council.
Input Tax Credit (ITC): As businesses can claim ITC on the paid SGST and use it to pay their SGST liabilities, this prevents any cascading effect of taxes. Hence, the overall burden on businesses reduces as they don’t have to pay the same tax twice.
Exemptions and Thresholds: Within the SGST scope, some goods and services are exempt from SGST. This means small businesses below the turnover threshold are not required to register or collect SGST.

Difference Between CGST and SGST

CGST and SGST, both apply on intrastate transactions, but they differ in terms of who collects, who apportions, and who benefits from these taxes.

Parameter	CGST	SGST
Full Form	Central Goods and Services Tax	State Goods and Services Tax
Imposing Authority	Central Government of India	Respective State Government
Collection Authority	Central Government	State Government where consumption occurs
Revenue Flow	Central Government (may share with states for specific schemes)	Remains with the State Government
Share of Tax	50% of total GST on intrastate supply	50% of total GST on intrastate supply
Applicability	Intrastate supply (within same state)	Intrastate supply (within same state)
Registration Requirements	₹40 lakh turnover for goods, ₹20 lakh for services (₹20/10 lakh for special category states)	Same as CGST
ITC Utilization	CGST credit can offset CGST or IGST liability only	SGST credit can offset SGST or IGST liability only
Cross-Utilization	Cannot be used to pay SGST	Cannot be used to pay CGST
Accounting	Reported separately in GST returns	Reported separately in GST returns
Governing Law	CGST Act, 2017	State-specific SGST Act (e.g., Maharashtra SGST Act, 2017)

But Why Do Both CGST and SGST Exist?

Both the centre and the states in India have vested powers by the Indian constitution to levy taxes on goods and services within their territories. Before GST, the centre had different taxes to look after like excise duty, service tax, and more. The states imposed VAT and a wide range of local taxes.

The GST model while preserving the federal balance has brought unison in the taxation structure. Today, while following the One Nation One Tax philosophy, GST has unified the indirect tax system and ensures both the centre and state reserves their right to collect taxes.

CGST and SGST is the representation of this right where both can tax as per their own understanding and generate revenue without creating separate tax systems.

While there is a difference between CGST and SGST, the balanced revenue sharing between centre (CGST) and states (SGST) ensures;

States maintain fiscal autonomy and don’t lose revenue post-GST implementation.
The Central government funds national projects and programs.
Consuming states benefit from economic activity, promoting equitable development.
Both governments have adequate resources for their respective responsibilities.

Understanding the key difference between CGST and SGST is critical to harmonize taxation across the country and ensure proper accountability.

SGST Act 2017 – Legal Framework and Key Provisions

Every state in India with a legislature has enacted their own SGST Act to impose and collect taxes. For instance, there is Maharashtra State Goods and Services Tax Act, Delhi Goods and Services Tax Act, Tamil Nadu Goods and Services Tax Act, and more.

Even though there is separate state-specific legislation, all the SGST Acts maintain uniformity in their core provisions, ensuring, Tax Rates, Definitions, Procedures, Compliance Requirements remain consistent across India.

Key Sections of the SGST Act

Section 7 – Scope of Supply: This section defines what is considered as “supply” under GST. Hence, it helps understand when the taxable event will trigger. The section covers supply of goods and services meant for the consideration in the course of business, including imports and activities.
Section 9 – Levy and Collection of SGST: This section empowers state governments to levy SGST on intrastate supply of goods and services. However, it also shares that the SGST must only be levied at the rates recommended by the GST Council.
Section 12 – Time of Supply of Goods: Determines SGST liability for goods-related transactions. This section identifies when the liability for SGST will arise, which can be anyone among, earliest invoice date, payment receipt, or goods delivery. This helps know in which tax period SGST must be paid.
Section 13 – Time of Supply of Services: Identical to Section 12, this section determines the SGST liability according to the invoice issuance, payment receipt, or service completion. Whichever is earlier, SGST is levied on that instance.
Section 15 – Value of Taxable Supply: Sets the structure to determine transaction value on which SGST is calculated. This includes the price paid plus incidental expenses, including packaging, commission, and freight charges.
Section 16 – Eligibility and Conditions for Taking Input Tax Credit: This section outlines when and how businesses can claim SGST credit. It sets the conditions for eligibility of claiming ITC, including having tax invoices, receiving goods/services, filling returns, and the supplier depositing the collected tax.

ITC is a fundamental concept in the GST and is important to understand a comprehensive answer to what is SGST.

Meant to prevent the cascading effect of taxes, it allows businesses to claim credit for taxes paid on purchases against their output liability (tax).

In SGST, ITC utilisation can take different forms;
1. SGST credit can offset SGST liability, that is, taxes to be paid by businesses.
2. SGST credit can offset IGST liability, similar to the previous point, this is used to pay IGST on interstate supplies.
3. SGST credit cannot be used to offset CGST liability.

Section 17 – Apportionment of Credit and Blocked Credits: Here you can find details on how to apportion on ITC when inputs are used for both taxable and exempt supplies. It also lists blocked credits, that is, items on which ITC cannot be claimed.
Section 20 – Registration Provisions: This section mandates registration for businesses exceeding turnover thresholds and specifies to register without considering their turnover.

In addition to these, Sections 37 to 44 cover the return filing requirements under SGST. Sections 49 to 53 covers deals with payment mechanisms and electronic credit/cash ledgers. Lastly, Sections 54 to 58 govern the refund process when businesses have paid excess SGST.

SGST Return Filing | Important GST Returns

GSTR-1: Outward Supplies

GSR-1 is filed every month or every quarter and the reports list all outward supplies. Businesses filing this return must decorate invoice-wise details of sales, SGST amount charged on intrastate supplies, and CGST amount charges. The due date to file this return is 11th of every month.

GSTR-3B: Summary Return

A key return for SGST payments and credit utilisation, it provides the summary of total outward and inward supplies. Business filing this return must show SGST liability on sales, SGST ITC claimed, and calculates the net SGST payable after ITC adjustment. The due date to file GSTR-3B is the 20th of every month.

Note that in all GST returns, SGST and CGST are reported in different columns. This means businesses need to maintain a separate electronic credit ledger for CGST and SGST balances. The liability calculation and credit utilisation is also shown distinctly.
