Understanding GST due dates
Most regular businesses have two recurring GST deadlines each month: GSTR-1 (your outward sales) by the 11th, and GSTR-3B (the summary return where you pay tax) by the 20th. Miss either and a per-day late fee starts, plus interest on any unpaid tax — and your buyers’ input credit is held up until your GSTR-1 is filed.
If you’re on QRMP
Businesses under ₹5 crore who opt for the QRMP scheme file GSTR-1 and GSTR-3B quarterly instead. In Gujarat, the quarterly GSTR-3B is due on the 22nd of the month following the quarter. You still pay tax monthly (PMT-06 by the 25th) and can push B2B invoices to buyers via the optional IFF by the 13th.
Never miss a date
The simplest safeguard is to not track this yourself. Under our ₹499/month filing plan, we watch every deadline for you, remind you for documents, and file on time — including Nil months. If you’d like that off your plate, talk to us.
