GST · checked 11 November 2026

Apply free on gst.gov.in once turnover crosses ₹40 lakh for goods or ₹20 lakh for services, or before your first sale across states.

Part A gives a Temporary Reference Number and Part B takes the business details; approval takes about 7 working days, or three under Rule 14A if monthly output tax stays within ₹2.5 lakh. Selling across states or on Amazon and Flipkart needs a GSTIN from the first order, and stock held in another state's warehouse usually needs a registration there. Since 22 September 2025 most goods sit at 5% or 18%, so check your HSN code's current rate.
