GST Registration in India: A Simple Step-by-Step Guide
GST registration gives your business a unique GST Identification Number (GSTIN) and lets you collect GST, claim input tax credit and issue proper tax invoices. But not every business needs it from day one — so when is it actually mandatory?
Registration becomes compulsory once your aggregate turnover crosses the prescribed threshold, which differs for goods and services and by state. It is also mandatory — regardless of turnover — for businesses making inter-state supplies and for most e-commerce sellers.
The process itself is fully online: you submit your PAN, Aadhaar, business address proof and bank details, complete Aadhaar authentication, and the department issues your GSTIN, usually within a few working days.
Once registered, you must file periodic returns (such as GSTR-1 and GSTR-3B) on time, even for months with no sales. Missing deadlines attracts late fees and can block your input tax credit.
