Compliance Snapshot
This GSTIN shows excellent compliance indicators. Safe for transactions and ITC claims.
This is a regular taxpayer, so it charges GST on its invoices. You can claim ITC once it reports your invoice in its GSTR-1 and the invoice appears in your GSTR-2B.
It isn't enabled for e-invoicing on the GST portal, so its B2B invoices don't need an IRN or QR code.
Its GSTR-1 filings have been late or missing in places. An invoice reported late shows up late in your GSTR-2B, which delays the ITC you can claim on it.
Filed GSTR-1 by the due date for 0 of 4 months on record, on average 18 days after the due date; the longest delay was 32 days.
Filed GSTR-3B by the due date for 1 of 4 months on record, on average 12 days after the due date; the longest delay was 35 days.
Based on returns on record as of 27 Aug 2026, measured against the standard due dates
(GSTR-1: 11th of the next month, 13th for quarterly filers; GSTR-3B: 20th, or 22nd/24th for quarterly filers).
One-off government extensions aren't counted.
