What is GSTN

The Goods and Services Tax Network (GSTN) is a unique and intricate IT enterprise that establishes a channel of communication and interaction between taxpayers, the central and various state governments, and other stakeholders. This single consolidated IT platform has given shape to the main objective of Goods and Services Tax (GST), i.e., One Nation, One Tax, One Market.

For compliance and administrative purposes, the GSTN has brought together millions of taxpayers who were earlier registered on different tax platforms under a consolidated umbrella. Consequently, any business entity registered on GSTN shall be allotted a 15-digit Goods and Services Tax Identification Number (GSTIN) to replace the old Tax Identification Number (TIN) allotted by respective states under Value-added Tax (VAT) registration. 

Structure of GSTN

The uniqueness of the Goods and Services Tax Network lies in its endeavor to act as a uniform interface for the taxpayers and governments along with a shared, common technology infrastructure between the central and the state governments.


  • Structurally, 51% of GSTN’s stake is held by private entities, and the government owns the remaining 49%.

  • GSTN’s authorized share capital is Rs. 10 Crores, 49% of which is equally distributed between the Central and various state governments, with the remaining 51% distributed between private banks.

  • Further, a non-recurring grant of Rs. 315 Crores was sanctioned for its sophisticated backend development by Infosys Technologies Ltd.

Features of GSTN

  • Manages Gargantuan Operations: The GSTN can process a heavy volume of complex transactions, such as adjustment of inter-state GST (IGST). This is made possible through its robust and secure IT infrastructure that facilitates a swift exchange of data between the taxpayers and the GSTN. The primary purpose of GSTN is to assist taxpayers in registering, paying taxes, and claiming GST returns in order to, among other things, produce business analytics. Additionally, the network is in charge of computing and paying the Integrated GST (IGST) and the Input Tax Credit (ITC). Thus, the GST network concentrates on offering comprehensive answers to complex and exhaustive taxing problems.

  • Reliable National Information Utility (NIU): The GSTN is tagged as the most reliable NIU, making it in charge of providing a secure and strong IT infrastructure that enables a verifiable information exchange. The GST Network serves as a reliable national information service (NIU). This basically means that the network is responsible for delivering dependable, strong, seamless information passing, and IT infrastructure.

  • Ownership: The ownership of GSTN is distributed between the government (49%) and private entities (51%) that comprise banks and financial institutions. However, a major share of the GSTN is owned by the Central government compared to any individual stakeholder.

  • Payment Mode: The GST Network allows payment by taxpayers through both online and offline modes:

  1. Online Mode: Internet banking facilities can be availed for online payment. The Reserve Bank of India (RBI) has authorized specific banks, known as the Agency banks, to collect payments made in favor of GST. The taxpayer shall make a payment by logging onto the selected agency bank’s web portal and downloading a challan of the GST transaction done. Once the choice is made, the taxpayer must log in to the online banking platform of the chosen bank to proceed with the transaction and download the GST payment challan.

  2. Offline Mode: GST payment online can be availed through the ‘over the counter option at any select agency bank. The agency bank shall further communicate the payment details to the RBI and the GSTN for its updation. To pay the GST, you can go directly to the relevant bank. The bank will also update all pertinent information by notifying the RBI and the GST portal.

  • Information Security: A major portion of the responsibility to preserve the security and confidentiality of GSTN data lies with the central government. It shall manage the board’s composition, shareholder’s agreement, resolution mechanisms, and any agreements forged between the state governments and the network. 

  • Financial Maintenance: The expenses incurred towards utility, infrastructure maintenance, and any other operations of the GSTN shall be paid in equal share by the central and state governments. Each state’s share of expenses shall be calculated in proportion to the number of taxpayers in the state.

Functions of GST Network

Once the registration has been confirmed, GSTN issues the GST Identification Number to the appropriate taxpayer and uploads the information with the appropriate tax authorities.

  • Tallying Invoice: This is a key function performed by the GSTN to cull out any discrepancies between the purchase invoices and sales invoices and resolve them so that the Taxpayer can avail of the Input Tax Credit (ITC) benefits. In order for taxpayers to benefit from Input Tax Credit, the GST network essentially compares the purchase and sale invoice totals to look for any discrepancies and correct them.

  • Filing Returns: GSTN has a unified, hassle-free return filing method for any GST, be it State GST (SGST), IGST, or Central GST (CGST), without burdening the Taxpayer.
