GSTR-1

Monthly/quarterly return for outward supplies (sales) filed by GST-registered businesses.

Full Definition

GSTR-1 is the return for outward supplies — all sales made during the month/quarter. It includes B2B supplies (invoicewise), B2C supplies, credit/debit notes, exports, and advance receipts. Monthly filers must file by the 11th of the following month. Quarterly filers (QRMP scheme) file by the last day of the month after the quarter. The details in GSTR-1 auto-populate in buyers' GSTR-2A and GSTR-2B, allowing ITC claims. Non-filing blocks ITC for buyers.
