New E-invoicing Threshold: ₹10 Crore Compliance Guide

With India’s evolving digital taxation landscape, e-invoicing compliance has become a critical requirement for mid-sized businesses. The recent update expanding the 30-day reporting mandate to businesses with Annual Aggregate Turnover (AATO) of ₹10 crore and above, effective from April 1, 2025, marks a significant shift in GST compliance requirements. This comprehensive guide provides essential implementation strategies and compliance requirements for businesses navigating these new regulations.

Understanding the New E-invoicing Threshold

Current Applicability and Phased Implementation

E-invoicing in India has undergone systematic implementation across different turnover segments. Currently, all businesses with annual turnover exceeding ₹5 crore must generate e-invoices for B2B transactions. The government has implemented this requirement through six distinct phases, progressively reducing the turnover threshold from ₹500 crore in October 2020 to ₹5 crore in August 2023.

The phased rollout demonstrates the government’s strategic approach:

The New 30-Day Reporting Rule

Starting April 1, 2025, businesses with AATO of ₹10 crore and above must report e-invoices within 30 days of generation. This rule, previously applicable to businesses with turnover above ₹100 crore, now encompasses a much larger segment of mid-sized businesses. Non-compliance with this timeline will result in automatic rejection by the Invoice Registration Portal (IRP), making such invoices invalid for Input Tax Credit (ITC) claims.

Key Implementation Requirements

System Setup Prerequisites

Successful e-invoicing implementation requires comprehensive ERP reconfiguration and system integration. Businesses must ensure their Enterprise Resource Planning (ERP) systems comply with PEPPOL standards and can generate invoices in the prescribed JSON format.

Essential system requirements include:

• ERP System Compatibility: Configure existing accounting software to support e-invoice schema and JSON file generation
• API Integration: Establish direct connectivity with IRP through GST Suvidha Providers (GSP) for automated invoice submission
• Data Validation Mechanisms: Implement real-time validation to ensure all mandatory fields are populated correctly
• User Authentication: Set up Two-Factor Authentication (2FA) for secure portal access, mandatory from April 2025

Mandatory Field Requirements

E-invoices must contain 29 mandatory fields across five critical sections. These include:

Basic Invoice Details:

• Supplier GSTIN, name, and address
• Consecutive serial number (maximum 16 characters)
• Invoice date and unique identification
• Document type specification

Recipient Information:

• Buyer GSTIN (for registered entities)
• Complete address with state code
• Delivery address (if different from buyer address)

Transaction Specifics:

• HSN/SAC codes for goods/services
• Detailed item descriptions
• Quantity and unit specifications
• Tax rates and amounts (CGST, SGST, IGST)

Financial Components:

• Taxable value calculations
• Discount adjustments
• Total invoice value including taxes
• Place of supply information

Step-by-Step Implementation Process

Phase 1: Assessment and Planning

Begin implementation by conducting a comprehensive business assessment. Evaluate current invoicing volume, existing ERP capabilities, and staff technical expertise. Businesses typically handle between 100-500 invoices monthly, requiring scalable solutions for efficient processing.

Key assessment parameters:

• Monthly invoice generation volume
• Current ERP system capabilities
• Staff training requirements
• Budget allocation for system upgrades

Phase 2: Software Selection and Integration

Choose an e-invoicing solution that integrates seamlessly with your existing accounting system. Popular integration options include direct API connections, GSP-mediated solutions, or standalone e-invoicing platforms.

Critical selection criteria:

• Real-time IRP Integration: Ensures automated invoice submission and IRN generation
• Bulk Processing Capability: Supports high-volume invoice generation for mid-sized businesses
• Error Handling Mechanisms: Provides validation alerts and correction suggestions
• Compliance Updates: Automatically incorporates regulatory changes

Phase 3: Data Migration and Testing

Execute systematic data migration ensuring all historical invoice formats align with e-invoice schema requirements. Conduct thorough testing using sandbox environments before live implementation.

Testing protocols include:

• JSON file generation validation
• IRN creation verification
• QR code functionality testing
• Integration stability assessment^[17]

Phase 4: Staff Training and Go-Live

Implement comprehensive staff training covering JSON file creation, IRP portal navigation, and error resolution procedures. Training should encompass both technical and compliance aspects, ensuring teams understand the 30-day reporting mandate.

Penalties and Non-Compliance Consequences

Financial Penalties

Non-compliance with e-invoicing requirements attracts severe monetary penalties under Section 122 of the CGST Act, 2017. The penalty structure is designed to ensure strict adherence to digital compliance requirements:

Primary Penalty Categories:

• Non-generation of e-invoice: 100% of tax amount OR ₹10,000 per invoice, whichever is higher
• Incorrect e-invoice generation: Flat penalty of ₹25,000 per invoice
• Late reporting beyond 30 days: Automatic rejection and ITC claim invalidation

Operational Consequences

Beyond monetary penalties, non-compliance creates significant operational disruptions:

Business Impact Areas:

• Input Tax Credit Loss: Invalid invoices cannot be used for ITC claims, affecting cash flow
• Goods Detention: Transportation without valid e-invoices can lead to goods and vehicle confiscation
• Customer Relationship Impact: Buyers cannot claim ITC on non-compliant supplier invoices
• Legal Proceedings: Systematic non-compliance may trigger prosecution and arrest of responsible officials
