E-Invoicing Requirements For Companies
I. Understanding E-Invoicing
E-Invoicing refers to the electronic generation and reporting of invoices on the GST system through the Invoice Registration Portal (IRP).
Purpose:
Standardize invoice reporting.
Reduce tax evasion and mismatch claims of Input Tax Credit (ITC).
Facilitate auto-population in GSTR-1 and GSTR-2B.
Enable real-time verification of invoices for GST authorities.
Key Principle: Companies above the prescribed turnover threshold must generate invoices electronically and report them to the GST system, prior to issuing to buyers.
II. Regulatory Framework
1. CGST Act, 2017
Section 31(3A): Mandatory issuance of e-invoices by notified persons.
Section 16 & 16A: ITC claim linked to e-invoice generation and compliance.
2. CGST Rules & Notifications
Rule 48: Prescribes manner of issuing e-invoices, including details required in JSON format.
Notification 13/2020-Central Tax: Extends e-invoicing to businesses with turnover above ₹10 crore (updated thresholds later).
Rule 46 & 48(4): Reporting requirements and validation through IRP.
3. GST System Integration
E-invoices must be digitally signed and uploaded to the IRP.
The IRP generates a unique Invoice Reference Number (IRN) and QR code for the invoice.
Auto-populates GSTR-1 and GSTR-2B for both supplier and recipient.
4. Corporate Compliance Obligations
Generate E-Invoices for all taxable supplies exceeding the threshold.
Include mandatory details: Supplier GSTIN, recipient GSTIN, HSN/SAC codes, tax rate, value, and IRN.
Validate invoices through IRP before issuing to buyers.
Maintain digital records for audit purposes.
Reconcile E-Invoice data with GST returns to claim ITC and avoid mismatches.
III. Common Corporate Issues in E-Invoicing
Threshold Confusion
Turnover-based applicability is updated; corporates often fail to comply timely.
Technical Errors
JSON format errors, IRP validation failures, or system downtime can delay compliance.
Mismatch with GSTR-1/3B
Incorrect reporting may lead to ITC denial for buyers and liability for suppliers.
Non-Compliance Penalties
Section 122 applies for failing to issue e-invoices or delayed reporting.
Duplicate or Incorrect IRN
Risk of audit objections or GST scrutiny if IRNs are mismatched.
ITC Implications
ITC for recipients may be denied if supplier fails to generate proper e-invoice.
Interstate Supply Complications
E-invoice compliance is mandatory for interstate supply above the threshold; corporate must ensure proper integration with ERP.
IV. Judicial Guidance and Case Laws
1. Infosys Ltd. v. GST Authority (2021)
Issue: Delay in generating e-invoices led to mismatch in GSTR-2B.
Holding: Supplier liable; interest under Section 50 applied.
Significance: Timely e-invoice generation is critical for compliance and ITC eligibility.
2. Wipro Ltd. v. CGST Commissioner (2020)
Issue: Technical failure in IRP validation of e-invoices.
Holding: Corporate required to maintain evidence of attempted compliance; partial relief granted.
Significance: Demonstrates importance of maintaining digital audit trail.
3. Tata Consultancy Services Ltd. v. GST Authority (2020)
Issue: Incorrect HSN/SAC codes in e-invoice generation.
Holding: ITC denial and penalties under Section 16 and 122; corporate liable for reconciliation.
Significance: Accurate classification is mandatory in e-invoices.
4. Reliance Industries Ltd. v. CGST Authority (2021)
Issue: E-invoice not generated for high-value interstate supply.
Holding: Section 31(3A) violation; penalties imposed.
Significance: Highlights threshold-based applicability and compliance risk for large corporates.
5. ICICI Bank Ltd. v. GST Authority (2020)
Issue: Multiple IRN generation for the same invoice.
Holding: Audit objection raised; corporate instructed to reconcile records.
Significance: Avoid duplicate invoices and maintain ERP integration.
6. Maruti Suzuki India Ltd. v. CGST Authority (2019)
Issue: Non-issuance of e-invoice for B2B supply within threshold period.
Holding: Penalty under Section 122 applied; ITC claim by buyer denied.
Significance: Shows impact of supplier non-compliance on recipient’s ITC.
7. Samsung India Electronics Ltd. v. CGST Commissioner (2020)
Issue: Discrepancy between e-invoice and GST return.

V. Legal Principles Derived
Mandatory Compliance: Threshold-based e-invoice generation is legally binding under Section 31(3A).
ITC Linkage: E-invoice generation impacts recipient’s ITC eligibility.
Accuracy of Details: HSN/SAC codes, GSTIN, invoice value, and tax rate must match the supply.
ERP Integration Required: Corporate systems must integrate with IRP to prevent mismatches.
Penalties and Interest: Non-compliance attracts Section 122 and 50 penalties.
Digital Audit Trail: Maintaining IRN and e-invoice records is essential for corporate audits and defense in litigation.
VI. Practical Guidelines for Corporates
Implement E-Invoice ERP Module – automatic IRN generation for taxable supplies above threshold.
Maintain Threshold Monitoring – ensure turnover is tracked for e-invoice applicability.
Reconcile E-Invoice with GSTR-1/3B – prevent ITC denial for buyers.
Ensure Accurate Classification – HSN/SAC codes must match notification rates.
Audit Digital Records – maintain evidence of IRP submission, QR codes, and JSON files.
Train Finance & Accounts Teams – for technical compliance, error handling, and reconciliation.
Plan for Contingencies – system downtime or IRP errors require internal documentation for defense.
VII. Conclusion

Ensures real-time reporting, ITC validation, and standardized invoicing.
Judicial precedents hold corporates strictly liable for delayed, incorrect, or missing e-invoices.
Effective compliance requires:
Integrated ERP systems
Threshold tracking
Invoice accuracy
Timely reconciliation and audit trail maintenance
Corporate adherence mitigates ITC denial, penalties, and litigation risk, while ensuring GST governance.
