Implementation of mandatory e-invoicing in India

India adopted e-invoicing under GST law to increase transparency and reduce tax evasion:
- Starting October 2020, e-invoicing became mandatory for businesses with turnover over ₹500 crore. This threshold was progressively lowered.
- By August 2023, the limit was reduced to ₹5 crore, bringing many SMEs under the system. Invoices must be submitted to the Invoice Registration Portal (IRP) for validation and QR code generation.
