1. Why GST Registration is Mandatory for Online Sellers

E-commerce sellers are required to register for GST irrespective of their annual turnover because:

• Online marketplaces deduct Tax Collected at Source (TCS), which requires a GSTIN for reconciliation.
• GST compliance ensures smooth transactions with platforms.

For offline sellers, GST registration is only required if their annual turnover exceeds ₹40 lakhs (₹20 lakhs for special category states).

2. Documents Required for GST Registration

Before you start, gather these documents:

• PAN Card (Individual or Business).
• Aadhaar Card linked with your mobile number.
• Business Address Proof: Rental agreement, electricity bill, or property tax receipt.
• Bank Account Details: Cancelled cheque or bank statement.
• Photograph: Passport-sized of the applicant.
• Proof of Business Constitution: Partnership deed, incorporation certificate, etc.
