Issuing the Invoice

Time of supply for goods or service is when GST becomes payable. Issuance of a tax invoice is an important element in determining the time of supply. In most scenarios, the time of supply of goods or service is the date of issuance of an invoice or receipt of payment, whichever is earlier. The supplier should produce the invoice within a period of 30 days from the date of providing the goods or services. Hence, the concerned individual shall provide the GST invoice after reasonable assurance of payment for goods or services or after supplying the to the recipient. It's very important to note that the supplier becomes liable for remittance of GST to the government on the issuance of tax invoice, even if payment has not been received from the customer. Hence, if payment is not reasonably assured and goods or services have not been delivered, an estimate can be issued by the supplier. Read about the GST Software – Getting Started with LEDGERS

Procedure for Issuing GST Invoice

The concerned individual shall prepare all the GST invoices in triplicate in case of a supply of goods. However, the individual shall mark the original copy as Original For Recipient and the duplicate copy should indicate Duplicate For Transporter and the triplicate copy should indicate Triplicate For Supplier. The concerned individual shall prepare the duplicate, in the case of the supply of services, in the following manner, namely, the original copy marked as Original For Recipient. In case of supply of services, the entity shall prepare the invoice as duplicate. The original copy should specify Original For Recipient and the duplicate copy should specify Duplicate For Supplier.

Filing GST Invoice on GST Portal

The serial number of all invoices issued during a tax period should be filed every month in FORM GSTR-1. Also, GSTIN of all recipients registered under GST must be mentioned on GSTR-1 filing for B2B transactions. In case of recipients not registered under GST or B2C transactions, name, address and place of supply should be mentioned for high value transactions. GSTR-1 filing made by the supplier will automatically be auto-populated in the GSTR-2 filing to be submitted by the recipient of goods or service. Hence, GST invoicing plays an important role in input tax credit claims.
