Navigating GST Changes: 5 Essential Updates on E-Way Bill and E-Invoice

As we step into the new financial year 2025-26, businesses must gear up for key compliance changes in GST, particularly concerning E-Invoicing and E-Way Bills. These aren’t just procedural formalities—they’re critical documents that validate tax liability and the movement of goods.
Failure to comply can attract severe consequences, including denial of Input Tax Credit (ITC), penalties of up to 200% on goods in transit, and post-supply penalties of up to 100%. With changes in invoice series and reporting timelines, it’s crucial to update your systems and internal processes accordingly.
Here’s a quick roundup of 5 significant updates you need to be aware of from April 1, 2025 onward.
Multi-Factor Authentication (MFA) Now Mandatory for All
The government has now made Multi-Factor Authentication (MFA) compulsory for all users accessing the e-Invoice and e-Way Bill portals from April 1, 2025. Previously applicable only to large taxpayers (AATO > ₹100 Cr), the MFA threshold was gradually lowered and is now applicable to all registered taxpayers, regardless of turnover.
MFA requires login via:
Username and password
OTP sent to the registered mobile number/Sandes app
✅ Action Point:
Ensure your GST-registered mobile numbers are active and up to date. Sub-users must be created with valid mobile numbers to avoid last-minute access issues.

Case-Insensitive IRN Validation Starts June 1, 2025
To streamline the invoice registration process, the Invoice Registration Portal (IRP) will treat invoice numbers as case-insensitive from June 1, 2025. For instance, “abc123”, “ABC123” or “Abc123” will all be considered the same.
This aligns with the treatment in GSTR-1, where invoice numbers are already case-insensitive, and will help avoid IRN duplication due to case mismatch.
✅ Action Point:
Standardize invoice number formats in your accounting system—preferably in uppercase—to prevent mismatches during IRN generation.
30-Day Time Limit for E-Invoice Reporting – Now for AATO > ₹10 Cr
From April 1, 2025, businesses with an Annual Aggregate Turnover exceeding ₹10 Cr will no longer be allowed to report e-Invoices older than 30 days on the IRP portal.
For example, an invoice dated April 1, 2025 must be reported by April 30, 2025. This applies to all document types requiring IRN, including credit and debit notes.
✅ Action Point:
Integrate your ERP/accounting systems with IRP to enable real-time e-Invoice generation.
Train your internal teams to adhere strictly to the 30-day reporting window, as late filing can result in ITC denial to buyers.
Note: This restriction does not currently apply to businesses with AATO between ₹5 Cr and ₹10 Cr, although e-Invoicing remains mandatory for them.
E-Way Bill Generation Timeframe Restricted to 180 Days
Effective January 1, 2025, E-Way Bills can only be generated for documents issued within the last 180 days.
For instance, from January 1, 2025, you cannot generate an E-Way Bill for documents dated before July 5, 2024.
✅ Action Point:
Check the document date carefully before generating E-Way Bills. Delayed dispatches may need revised documentation.

E-Way Bill Extension Limit: Max 360 Days
Also from January 1, 2025, E-Way Bills can only be extended within 360 days from their original date of generation.
For example, a bill generated on January 1, 2025 can only be extended until December 25, 2025. This restricts the earlier practice of indefinite extension in exceptional cases.
✅ Action Point:
Avoid planning long-term dispatches that could exceed the 360-day validity window.
Final Thoughts: Compliance is a Team Effort
The latest updates in GST E-Invoicing and E-Way Bill mechanisms emphasize the importance of automation, real-time reporting, and inter-department coordination. Compliance is no longer just the responsibility of finance or accounts—it involves your sales, logistics, and operations teams as well.
👉 Recommendations:
Upgrade ERP and accounting software for seamless IRN and E-Way Bill generation.
Train staff across departments on new SOPs aligned with legal timelines.
Consult GST professionals for a comprehensive compliance roadmap.
