The State Goods and Service Tax (SGST) is a significant component of India’s Goods and Services Tax (GST) system. It is an indirect tax levied by individual states and union territories on the supply of goods and services within their respective jurisdictions. In this blog, we will explore the details of SGST, explaining how it works, the role of GSTN (Goods and Services Tax Network), compliance, and its impact on state revenue.

Mechanism of SGST

SGST operates on a dual-tax structure, which means that both the central and state governments have the authority to levy and collect taxes on the same transaction. Here’s how the mechanism works:

Levy and Collection

State Goods and Service Tax (SGST) is levied by the state government on intra-state transactions. It applies to the supply of goods and services within the boundaries of a particular state or union territory.


Imagine you run a small clothing store in the state of Maharashtra, India. You sell a shirt for Rs. 1,000 to a customer who lives in Maharashtra as well.

Calculation Table:

Particulars Amount (in Rs.)
Selling Price of Shirt 1,000
SGST Rate (Assume 9%) 90
CGST Rate (Assume 9%) 90
Total Tax (SGST + CGST) 180
Total Invoice Amount 1,180

In this example:

  1. You sell a shirt for Rs. 1,000 within the state of Maharashtra.
  1. SGST is levied by the Maharashtra state government, and let’s assume the SGST rate is 9%. So, SGST is calculated as 9% of the selling price, which is Rs. 1,000 * 9% = Rs. 90.
  1. Similarly, CGST (Central Goods and Services Tax) is also applied at a rate of 9%, and it amounts to Rs. 90.
  1. The total tax amount on this transaction is the sum of SGST and CGST, which is Rs. 90 + Rs. 90 = Rs. 180.
  1. The total invoice amount that the customer pays includes both the selling price and the total tax, which is Rs. 1,000 + Rs. 180 = Rs. 1,180.

In this case, SGST and CGST are collected by the respective governments, and the total tax revenue of Rs. 180 goes to the state and central governments to fund various public services and infrastructure development.

Input Tax Credit (ITC)

One of the fundamental principles of GST is the seamless flow of Input Tax Credit under SGST. Businesses can claim ITC for the State Goods and Service Tax (SGST) paid on their purchases against the SGST liability on their sales. This helps avoid tax cascading or double taxation.


Imagine you run a manufacturing business in the state of Karnataka, India. You purchase raw materials worth Rs. 10,000 for your production process, and the SGST rate for these materials is 9%.

Calculation Table:

Particulars Amount (in Rs.)
Cost of Raw Materials 10,000
SGST on Raw Materials 900
Sales Revenue 20,000
SGST on Sales (9%) 1,800
Total SGST Liability 1,800
Input Tax Credit (ITC) 900
SGST Payment (Net SGST) 900

In this example:

  1. You purchase raw materials for your production process in Karnataka for Rs. 10,000. The SGST rate on these materials is 9%, so the SGST paid on the purchase is Rs. 900 (9% of Rs. 10,000).
  1. You manufacture products using these raw materials and sell them for Rs. 20,000. The SGST on the sale is calculated at 9%, which amounts to Rs. 1,800 (9% of Rs. 20,000).
  1. To calculate your net SGST liability, you can subtract the ITC from your SGST on sales. So, in this case, your net SGST liability is Rs. 1,800 (SGST on sales) – Rs. 900 (ITC) = Rs. 900.
  1. You only need to pay Rs. 900 as SGST to the government, as you can offset the SGST paid on your purchases (ITC) against your SGST liability on sales. This avoids double taxation or tax cascading.

The Input Tax Credit mechanism ensures that you are only liable to pay tax on the value you add to the product or service, and it promotes the smooth flow of credits across the supply chain.


Revenue Sharing

To ensure a fair distribution of tax revenue between the central and state governments, a mechanism is in place. The revenue collected under SGST is shared between the state and central governments as per the recommendations of the GST Council.


Consider a scenario where the total SGST collection for a particular state, let’s say Tamil Nadu, in a given month is Rs. 1,00,000. The GST Council recommends a revenue-sharing formula between the state and central governments, with a certain percentage allocated to each.

Calculation Table:

Particulars Amount (in Rs.)
Total SGST Collection (Tamil Nadu) 1,00,000
Percentage Share for State Government (e.g., 50%) 50,000
Percentage Share for Central Government (e.g., 50%) 50,000
State Government’s Share 50,000
Central Government’s Share 50,000

In this example:

  1. The state of Tamil Nadu collects a total of Rs. 1,00,000 in SGST revenue for a specific period.
  1. The GST Council, based on discussions and recommendations, decides on a revenue-sharing formula. Let’s assume that in this case, they agree on a 50-50 split, with 50% of the SGST revenue going to the state government and the other 50% to the central government.
  1. According to this formula, the state government’s share is calculated as 50% of the total SGST collection, which is Rs. 1,00,000 * 50% = Rs. 50,000.
  1. Similarly, the central government’s share is also 50% of the total SGST collection, which is also Rs. 50,000.

The 50-50 split used in the example is for illustrative purposes. In practice, the GST Council regularly reviews and adjusts the revenue-sharing formula based on various factors, such as the needs of states, economic conditions, and revenue trends. The actual percentage share allocated to each government may vary over time. While the example focuses on SGST, it’s essential to remember that the revenue-sharing mechanism encompasses the entire GST revenue collected, not just SGST. This includes CGST and IGST as well.

In this scenario, the SGST revenue of Rs. 1,00,000 is shared equally between the state and central governments, each receiving Rs. 50,000. This revenue-sharing mechanism ensures a fair distribution of tax revenue and helps in the cooperative federalism model of GST implementation in India.

Role of GSTN

The Goods and Services Tax Network (GSTN) plays a vital role in the functioning of SGST:

  1. Registration Process: GSTN manages the SGST registration process for businesses operating within a state or union territory. It provides a seamless online platform for businesses to register and obtain their unique GSTIN (Goods and Services Tax Identification Number).
  1. Calculation and Payment: GSTN facilitates SGST calculation and payment. Businesses can use the GSTN portal to file their SGST returns and make payments.
  1. Input Tax Credit: GSTN ensures that the input tax credit mechanism functions smoothly under SGST. It allows businesses to claim and verify ITC on eligible transactions, reducing the overall tax burden.
  1. Data Management: GSTN stores and manages taxpayer data securely. This data is important for the purposes of tax administration, compliance verification, and regular tax audits.

Compliance and Regulatory Aspects

Compliance with SGST regulations is essential for businesses to avoid penalties and legal hassles. Here are some key compliance and regulatory aspects:

  • Filing SGST Returns: Businesses are required to file periodic SGST returns, which include details of their sales and purchases. Timely and accurate filing is crucial to ensure compliance.
  • Payment of SGST: Businesses must ensure that they pay the SGST liability on time to avoid interest and penalties. The GSTN portal makes it convenient for taxpayers to make payments.
  • Record Keeping: Maintaining proper records of invoices, receipts, and other financial documents is essential for SGST compliance. These records help in the reconciliation of input tax credit.
  • GST Audit: The government may conduct GST audits to verify compliance. It is essential for businesses to cooperate with audit authorities and provide the necessary documents and information.

Impact of SGST on State Revenue

  • Increased Revenue: SGST has led to an increase in state revenue, as it allows states to collect taxes on a broader tax base. This additional revenue can be used for development and welfare programs.
  • Economic Growth: A simplified and uniform tax system like GST, promotes economic growth by reducing tax-related complexities and barriers to interstate trade.
  • Revenue Sharing: The mechanism of revenue sharing between the central and state governments ensures that states receive their fair share of revenue, promoting fiscal federalism.

While SGST has brought benefits like streamlined tax collection and improved economic integration, the impact of SGST on state revenue remains complex. Initially, concerns arose about potential revenue shortfalls, prompting the introduction of a guaranteed compensation mechanism. Though revenue has gradually grown, dependence on this compensation is reducing, making states strive for increased SGST efficiency and economic growth for sustainable revenue generation. 


The State Goods and Service Tax (SGST) has significantly reformed India’s tax system since its introduction. By replacing various state taxes, SGST has simplified tax processes, making it easier for businesses to comply and boosting state revenues. This change has been crucial for funding important state services. However, SGST also brings challenges, especially for smaller businesses adapting to new tax rules. Looking forward, continuous improvements in SGST are expected to further ease business operations and strengthen state economies.
