GSt E-Invoicing

GST E-Invoicing

E-invoicing, or electronic invoicing, is a system where Business-to-Business (B2B) invoices and certain other documents are electronically authenticated by the GSTN (Goods and Services Tax Network) for use on the common GST portal. It was initially introduced for large enterprises and has since been expanded to include mid-sized and small businesses. E-invoicing does not involve generating invoices on the GST portal itself. Instead, it involves submitting invoices that have already been generated using a standardized format on a common e-invoicing portal. This process automates multi-purpose reporting with a one-time input of invoice details. The Central Board of Indirect Taxes and Customs (CBIC) has notified specific portals for e-invoicing preparation. Under the e-invoicing system, each invoice is assigned a unique identification number by the Invoice Registration Portal (IRP), managed by the GSTN. This IRP facilitates the real-time transfer of invoice data to both the GST portal and the e-way bill portal. This integration eliminates the need for manual data entry when filing GSTR-1 returns and generating part-A of e-way bills, as the information is seamlessly transmitted from the IRP to the respective portals.

E-Invoicing Compliance

As of 30th April 2023, the GST system and GST law did not impose any specific time limit for generating e-invoices. However, starting from 1st May 2023*, a new e-invoicing compliance requirement comes into effect. Taxpayers with an Annual Aggregate Turnover (AATO) equal to or exceeding INR 100 crore are now mandated to generate e-invoices for tax invoices and credit-debit notes within 7 days of the invoice date. Failing to comply with this timeframe will result in such invoices and CDNs being considered non-compliant. For other applicable taxpayers, there is no defined time limit within which e-invoices must be generated. However, we strongly recommend generating e-invoices on or after the invoice/CDN date, preferably at least a week before filing your GSTR-1 returns. This is because it takes T+3 days for the details of e-invoices to auto-populate into your GSTR-1. *Note: On 6th May 2023, the department deferred the 7-day time limit for reporting old e-invoices on the IRP portals by three months. The department is yet to announce the new implementation date for this change." This revised content conveys the e-invoicing compliance requirements and the recent deferral in a clear and informative manner for your website.
