E-Invoice Under GST: Everything You Need to Know for 2025

E-Invoicing under GST is a digital invoicing system that requires businesses to report their invoices to a centralized Invoice Registration Portal (IRP) for authentication. This system aims to streamline GST compliance, reduce tax evasion, and improve transparency in business transactions.

This guide covers all you need to know about e-invoicing in 2025, including eligibility, benefits, and the compliance process.

E-invoicing refers to the electronic generation and reporting of business invoices in a standardized format to the GST system. After verification by the IRP, the invoice receives a unique Invoice Reference Number (IRN) and a digitally signed QR code, making it valid for GST purposes.

1. Simplify GST Compliance
   • Automate reporting and eliminate manual data entry errors.
2. Curb Tax Evasion
   • Enhance transparency by ensuring all invoices are reported to the GST system.
3. Streamline ITC Claims
   • Facilitate seamless Input Tax Credit (ITC) reconciliation for buyers.
4. Improve Invoice Tracking
   • Enable real-time tracking of invoices across supply chains.

Who is Required to Comply?

E-invoicing is mandatory for businesses with an annual aggregate turnover of ₹5 crore or more in any financial year from 2017-18 onwards.
