Businesses in India that meet the required turnover threshold or are involved in interstate commerce must complete the GST registration process. First, the GST REG-01 form must be completed on the GST portal. Essential information such as bank account information, Aadhaar, PAN, and business evidence must be provided by applicants. Authorities check the information after it is submitted. A GSTIN (Goods and Services Tax Identification Number) is granted upon approval, allowing companies to collect and submit GST while guaranteeing compliance with tax laws.
