Common questions
GST & E-commerce FAQ
- Do Amazon and Flipkart sellers need to register for GST?
- Yes — every e-commerce seller on Amazon, Flipkart, Meesho, or any marketplace must register for GST, regardless of turnover. This is mandatory under Section 24 of the CGST Act. The normal ₹40 lakh turnover threshold does not apply to marketplace sellers.
- What is GSTR-3B and when is it due each month?
- GSTR-3B is the monthly summary return where you declare your net tax liability and claim Input Tax Credit. For monthly filers it is due by the 20th of the following month. Sellers under the QRMP scheme (quarterly, turnover ≤ ₹5 crore) file by the 22nd or 24th depending on their state.
- What is Input Tax Credit (ITC) and can online sellers claim it?
- ITC lets you offset GST paid on business purchases against GST collected on sales, reducing your net tax liability. E-commerce sellers can claim ITC on inventory, logistics, packaging, and business services. ITC is blocked on personal-use goods and items used for exempt supplies.
- What is the GST turnover limit for goods sellers in India?
- The mandatory GST registration threshold is ₹40 lakh annual turnover for goods sellers (₹20 lakh for services, ₹10 lakh in special category states). However, if you sell on any marketplace — Amazon, Flipkart, Meesho, etc. — you must register for GST even if your turnover is below these limits.
- What happens if I miss a GST return filing deadline?
- Late filing attracts a penalty of ₹50/day (₹25 CGST + ₹25 SGST) for non-nil returns, capped at ₹5,000. Nil returns incur ₹20/day. Interest at 18% per annum applies on any unpaid tax. Use our GST Late Fee Calculator to compute your exact liability.
