GSTR-1 is a monthly or quarterly return that registered businesses must file under GST (Goods and Services Tax) in India. It contains details of outward supplies (sales) made during a tax period.
GSTR-1 form is a statement in which a regular dealer needs to capture all the outward supplies made during the month. Broadly, the GSTR 1 format requires — all the outward supplies made to registered businesses (B2B) to be captured at the invoice level, and supplies made to unregistered businesses or end consumers to be captured at a rate-wise level. However, in certain exceptional scenarios, even B2C transactions are required to be captured at the invoice level.
Form GSTR-1 contains 13 tables in which the outward supply details need to be captured. Based on the nature of business and the nature of supplies affected during the month, only the relevant tables are applicable, not all.
