Do I need GST to sell online in India?

Not always. If your annual turnover is below ₹20 lakh (₹10 lakh for special category states), GST registration is not mandatory. However, if you sell through any ecommerce operator — including your own store processing orders — some platforms require a GSTIN regardless of turnover. Check your state's threshold and your platform's policy.

What is an HSN code and how do I find the right one for my products?

HSN (Harmonised System of Nomenclature) codes classify goods under GST. Every product you sell needs the correct HSN code on its invoice. Find yours using the GST Council's HSN search tool at gst.gov.in. Common codes: cotton garments (Chapter 61/62), packaged food (Chapter 19/21), electronics (Chapter 85).

What is the difference between CGST, SGST, and IGST?

CGST and SGST apply to intra-state sales — sales where your business and the customer are in the same state. Each takes half the total GST rate. IGST applies to inter-state sales — where seller and buyer are in different states. IGST equals the full GST rate and is collected by the central government.

What details must appear on a GST invoice from an online store?

A valid GST invoice must include: supplier GSTIN and name, invoice number and date, buyer name and address (and GSTIN if B2B), HSN code, product description, quantity, taxable value, applicable GST rate, CGST/SGST or IGST amounts, and total amount. Missing any field makes the invoice non-compliant.

What is the GST Composition Scheme and is it right for small sellers?

The Composition Scheme lets businesses with turnover below ₹1.5 crore pay GST at a fixed low rate (1% for traders, 5% for restaurants) instead of filing full returns. You can't claim input tax credit and can't sell inter-state. It suits local-only retailers with low B2B dealings — not ideal if you ship across states.
