GST Registration Online: Step-by-Step Guide for New Businesses

GST registration is mandatory once your business crosses the threshold for taxable supply, or earlier for e-commerce sellers, inter-state suppliers, and certain notified categories. The process runs on the GST portal and finishes in 3–7 working days if your documents and photographs are clean. You will need a PAN of the entity or proprietor, Aadhaar of the authorised signatory, business address proof (rent agreement plus electricity bill or property tax receipt), a photograph of the signatory taken at the signboard of the business premises, and bank account proof (cancelled cheque or first page of passbook). On the portal you file REG-01 with the trade name, legal name, constitution, principal place of business, and additional places of business. After Aadhaar e-sign of the authorised signatory and the digital signature with DSC, the GST officer verifies the application. If everything is in order, the GSTIN and the registration certificate are issued within seven working days.
