IGST Full Form – Understanding Integrated Goods and Services Tax (IGST): A Comprehensive Analysis

The full form of IGST is Integrated Goods and Services Tax. This article explaining what IGST is, its significance, how it works, and its impact on the economy.

The implementation of the Goods and Services Tax (GST) in India marked a significant step towards tax reforms. Among the various components of the GST, the Integrated Goods and Services Tax (IGST) plays a crucial role in facilitating the seamless flow of goods and services across state borders. In this article, we will delve deep into the concept of IGST, its full form, how it functions, and the impact it has on the Indian economy.

What is IGST?

IGST stands for Integrated Goods and Services Tax, a term coined under the Goods and Services Tax (GST) regime in India. It is a comprehensive tax levied on the supply of goods and services when transactions involve inter-state movement. Unlike Central GST (CGST) and State GST (SGST), which are applicable within a state, IGST is applicable when goods or services are supplied from one state to another.

How does IGST work?

The IGST mechanism is designed to simplify tax administration and ensure the efficient movement of goods and services across state boundaries. When an inter-state supply occurs, the tax collected is shared between the center and the destination state. For example, if a supplier in Karnataka sells goods to a buyer in Maharashtra, the IGST collected will be shared between the central government and the Maharashtra government.

Significance of IGST

IGST plays a crucial role in fostering the concept of “One Nation, One Tax.” It eliminates the cascading effect of taxes on goods and services, which was prevalent under the previous tax regime. With IGST, taxes are collected at the destination state, ensuring that the tax burden is distributed more fairly and effectively.

Key Features of IGST

Seamless Tax Credit: IGST allows seamless tax credit across states, ensuring that input tax credits can be utilized regardless of the location of the supplier and the buyer.

Transparent Taxation: IGST enhances transparency in tax collection and revenue sharing, as it is a single tax collected on inter-state supplies.

Reducing Tax Evasion: The implementation of IGST helps curb tax evasion, as it creates a trail of transactions and simplifies the tracking of inter-state movements.

Simplified Compliance: Businesses benefit from simplified compliance under IGST, as they need to deal with a single tax authority for inter-state transactions.

Calculating IGST

Calculating IGST is a straightforward process. When goods or services are supplied from one state to another, the IGST rate is applied to the transaction value. The tax collected is then shared between the center and the destination state according to a pre-determined formula.

Impact of IGST on the Indian Economy

Boost to Inter-State Trade: IGST has facilitated the movement of goods and services across state boundaries, promoting inter-state trade and commerce.

Simplified Tax Structure: With IGST, the complexity of the tax structure has reduced, encouraging businesses to expand their operations beyond state borders.

Revenue Collection: IGST has improved tax collections and helped the government ensure a stable revenue stream.

Curbing Tax Evasion: The transparency brought by IGST has played a crucial role in curbing tax evasion, leading to a more equitable tax system.

Challenges and Limitations

Compliance Burden: Some businesses initially faced challenges in adapting to the new GST regime and understanding IGST compliance procedures.

Technical Issues: Implementing IGST required significant changes to tax administration and technical systems, leading to some initial hiccups.

Data Sharing: Effective data sharing between states and the center is crucial for the seamless implementation of IGST, which was a challenge during the initial phase.


Integrated Goods and Services Tax (IGST) is an essential component of the GST regime in India. Its implementation has significantly streamlined inter-state trade, curbed tax evasion, and improved revenue collection for the government. While there were initial challenges, the benefits of IGST have been noteworthy in creating a more transparent and efficient tax system. As the Indian economy continues to evolve, IGST will remain a vital instrument in ensuring a smooth flow of goods and services across state borders.
