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?

Due dates: GSTR-1 on the 11th (monthly) or 13th of the post-quarter month (quarterly); GSTR-3B on the 20th monthly; GSTR-9 annual return by 31st December after year-end. QRMP scheme filers pay monthly, file quarterly. Late filing costs ₹50/day per return (₹20/day if nil) plus 18% p.a. interest on any unpaid tax.

How long does GST Registration take in Kolkata?

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.
