Who is required to register for GST in India?

GST registration is mandatory if: (1) Annual turnover exceeds ₹40 lakh for goods (₹20 lakh for services; ₹10 lakh for NE/special category states). (2) You make interstate supply of goods or services. (3) You sell on e-commerce platforms (Amazon, Flipkart, etc.). (4) You are a casual taxable person or non-resident taxable person. Voluntary registration is allowed below these thresholds.

What are the GST return filing due dates in 2026?

Monthly filers submit GSTR-1 by the 11th and GSTR-3B by the 20th of the following month; quarterly filers submit GSTR-1 by the 13th of the month after the quarter. GSTR-9, the annual return, is due 31st December after the fiscal year ends. QRMP filers pay tax monthly via challan but file full returns quarterly. Miss a deadline and it's a ₹50/day late fee (₹20/day for nil returns) plus 18% annual interest.

How long does GST Registration take?

GST registration: 3–7 working days after document submission. GST returns (GSTR-1, GSTR-3B): filed within 24–48 hours of receiving your invoice data. We proactively track all due dates and send reminders so you never attract a late fee.

What is the penalty for late GST filing?

Late fee: ₹50/day per return (₹25 CGST + ₹25 SGST) for returns with tax liability; ₹20/day for nil returns (₹10 CGST + ₹10 SGST). Additionally, 18% per annum interest applies on tax not paid by the due date. Failing to file GSTR-3B for 6 consecutive months can lead to GST registration cancellation, causing loss of Input Tax Credit.
