Starting 1 April 2025, Indian businesses with annual turnover over ₹10 crore (approx. €112,000) will have to report B2B e-invoices to the Invoice Registration Portal (IRP) within 30 days of issue. Missing this deadline means losing the right to claim GST input tax credit. This rule already affects businesses with turnover above ₹5 crore. India has been steadily lowering the e-invoicing threshold since introducing it back in October 2020.
E-invoicing Process: Businesses have to first upload invoices to the IRP (Invoice Registration Portal) using API (special compute language) (in JSON format for invoices), where basic checks are done (e.g., GSTIN validation, no duplicates). Once approved, the IRP assigns a unique Invoice Reference Number (IRN), QR code, and digital signature. Invoices and QR codes have to be shared with customers (usually via PDF or paper), and are also sent to the GSTN and National Informatics Centre (NIC) for record matching.
B2C Expansion Plan: A voluntary B2C e-invoicing pilot will launch in select states and sectors, with complete rollout likely by 2026 or 2027.
E-Way Bill Integration: Eventually, e-way bills (needed for transporting goods worth over ₹50,000) will be combined with e-invoicing for B2B and export deals. This is intended to reduce tax fraud by aligning the reporting systems. Currently, B2C transactions are not affected and goods transported by train fall under e-way bill regulations.
HSN Code Requirements:
- Businesses with over ₹5 crore turnover must provide 6-digit HSN codes
- Businesses below must provide at least 4-digit codes on invoices.
November 2023 Update: The GSTN enforced a 30-day upload deadline to the IRP (effective 1 Nov 2023) for businesses with turnover above ₹100 crore, including for credit/debit notes. This replaced earlier plans for a 7-day deadline.
In April of 2023, electronic invoicing through the IRP was made optionally available to all taxpayers, including those beneath the required limits. But, to get the input tax credit (ITC), invoices need to be uploaded to the IRP.
