Do I Need GST Registration?

⚡ In shortNot sure if you need a GSTIN? Answer a few questions about your turnover and how you sell, and this tool tells you whether GST registration is mandatory or optional — and why. GST registration is mandatory once your aggregate annual turnover crosses ₹40 lakh for goods (₹20 lakh in special-category states) or ₹20 lakh for services (₹10 lakh in special-category states). It is also compulsory regardless of turnover if you make inter-state supply of goods, sell through an e-commerce operator, or are a casual/non-resident taxable person. Below the threshold you can still register voluntarily to claim input tax credit.
