GST registration is mandatory for businesses with turnover exceeding ₹40 lakh (₹20 lakh for services). It is also mandatory for e-commerce sellers, interstate suppliers, and certain other categories.

Yes, you can verify GSTIN on the official GST portal (gst.gov.in) using the 'Search Taxpayer' feature. This tool calls the same GSTN database via a live API and returns the legal name, trade name, registration date, central & state jurisdiction, nature of business, e-invoice applicability, compliance category and the full GSTR-1, GSTR-1A, GSTR-3B and GSTR-9 filing history.

Active status means the GST registration is valid and the taxpayer can generate e-invoices and claim input tax credit. 'Cancelled' or 'Suspended' status means registration is not active.

Verifying GSTIN ensures you're dealing with a genuine registered business, helps prevent fraud, and ensures you can claim input tax credit correctly on purchases. Under Section 16(2)(c) of the CGST Act, ITC can be denied if the supplier's invoice does not appear in your auto-populated GSTR-2B — so verifying the supplier's GSTIN status and filing history before booking an invoice is now an ITC-compliance hygiene step, not just a fraud-prevention measure.

GSTR-1A is a new return introduced by CBIC from the August 2025 tax period onwards. It allows suppliers to amend or add outward supply details after filing GSTR-1 but before filing GSTR-3B for the same month. Amendments made in GSTR-1A automatically flow into GSTR-3B for that tax period. If you see GSTR-1A entries in your filing history on this page, it means the supplier has used this amendment window.

From 1 April 2025 onwards, e-invoicing (IRN generation via the Invoice Registration Portal) is mandatory for taxpayers whose aggregate turnover in any financial year from 2017-18 onwards exceeds ₹1 crore (per Notification 10/2025-Central Tax). If the 'E-Invoice Mandated' field on this page shows 'Yes', the taxpayer must generate an IRN and QR code for every B2B invoice before issuing it to the buyer.
