GST RET-1 will contain details of all supplies made, input tax credit availed, and the payment of taxes, along with interest, if any. This return will contain two annexure forms namely GST ANX-1 and GST ANX-2. GST ANX-1 (Annexure of Outward Supplies) is for reporting details of all outward supplies, inward supplies liable to reverse charge, and import of goods and services, that will need to be reported invoice-wise (except for B2C supplies) on a real-time basis. GST ANX-2 (Annexure of Inward Supplies) will report details of all inward supplies. Most of these details will be auto-drafted from the details uploaded by the suppliers in their GST ANX-1. The recipient of supplies will be able to take action on these auto-drafted documents, which will be available to them on a real-time basis.
