GST Registration

Definition

GST registration is the formal process through which a business or individual becomes a registered taxable person under the Central Goods and Services Tax (CGST) Act, 2017. Upon successful registration, the applicant receives a 15-digit Goods and Services Tax Identification Number (GSTIN), which is unique to each state-wise registration and serves as the primary identifier for all GST compliance activities.

In India, GST registration is mandatory for businesses whose aggregate turnover exceeds Rs. 40 lakh (Rs. 20 lakh for special category states) for goods, and Rs. 20 lakh (Rs. 10 lakh for special category states) for services. Additionally, certain categories of persons, including inter-state suppliers, e-commerce operators, persons liable to pay tax under reverse charge, and non-resident taxable persons, must register regardless of turnover. The registration is obtained through the GST portal (gst.gov.in) by filing Form GST REG-01.

GST registration is not merely a one-time formality. Once registered, a business must file periodic returns (GSTR-1, GSTR-3B, and annual returns), comply with invoicing requirements including e-invoicing mandates where applicable, and maintain prescribed records. Failure to register when required attracts penalties under Section 122 of the CGST Act, including a penalty equal to the tax amount due or Rs. 10,000, whichever is higher.
