The Goods and Services Tax Network (GSTN) is a non-profit, private limited company that functions as the technological backbone for the Goods and Services Tax (GST) regime in India. It is an institution incorporated on March 28, 2013, under Section 8 of the Companies Act, 2013, which governs non-profit companies. The GSTN was created to solve the problem of fragmented, isolated IT systems used by the Central and State indirect tax administrations before the GST's introduction. Its purpose was to establish a common, shared IT infrastructure and a uniform interface for taxpayers across the country.
The GSTN's core mechanism is the operation of the common GST Portal, which serves as the single interface for taxpayers. It manages the entire IT system for GST operations, including taxpayer registration, return filing (like GSTR-1 and GSTR-3B), tax payment, and processing refunds. A key function is the settlement of Integrated Goods and Services Tax (IGST) between the Centre and States, which is complex due to GST being a destination-based tax. The GSTN connects to the Central and State tax authorities, the Reserve Bank of India (RBI), and various banks to facilitate these transactions.
The GSTN's structure has recently changed: initially, it was a non-government company with 51% equity held by private financial institutions and 49% by the government. However, the status of GSTN was changed to a Government Company in terms of Section 2(45) of the Companies Act, 2013, following the approval of its Board on June 30, 2022. This conversion made it a 100% Government owned enterprise, with the Union Government and State Governments/UTs jointly holding 50% shares each. The core function of providing the IT infrastructure for GST compliance has stayed the same.
