Major GST Updates Effective April 2025 Onwards: Key Changes in Compliance, Registration, and Reporting

As India continues to strengthen its indirect tax framework, several important changes under the Goods and Services Tax (GST) regime have been introduced, effective from April 1, 2025, and beyond. These reforms are aimed at enhancing ease of doing business, improving data accuracy, and reducing compliance challenges for taxpayers.
Biometric-Based Aadhaar Authentication for GST Registration (Effective in Assam)
A significant development under Rule 8 of the CGST Rules, 2017, is the introduction of biometric-based Aadhaar authentication for GST registration. Starting April 1, 2025, this functionality has been rolled out in Assam on a pilot basis.
Key Features:
Risk-Based Selection: Applicants may be selected for biometric authentication based on data analytics and risk parameters.
Two Types of Authentication:
OTP-Based: Usual Aadhaar OTP authentication.
Biometric-Based: Requires physical presence at a GST Suvidha Kendra (GSK) for fingerprint and document verification.
Mandatory Documents: Applicants must carry original Aadhaar and PAN cards, jurisdiction details, appointment confirmation, and all documents uploaded during the application process.
Timelines: The biometric process must be completed within the specified time for the ARN to be generated.
This initiative aims to curb fake registrations and enhance the authenticity of GST applicants.

Revised Formats for GSTR-7 (TDS) and GSTR-8 (TCS)
To promote transparency and traceability, the government has revised the formats for GSTR-7 (for Tax Deducted at Source) and GSTR-8 (for Tax Collected at Source by e-commerce operators).
GSTR-7 Updates
Mandatory invoice/document-wise reporting.
Requires details like deductee GSTIN, invoice number, payment amount, and tax deducted.
GSTR-8 Updates
More granular data capturing supplies made via e-commerce platforms.
Improved accuracy and compliance checks for digital commerce ecosystems.
Clarification: No GST on UPI Transactions Above ₹2,000
A clarification from the government has put to rest rumors regarding the imposition of GST on UPI payments above ₹2,000.
Highlights
No GST is levied on UPI transactions, irrespective of amount.
GST applies only on payment-related services (e.g., MDR).
Since January 2020, the MDR for P2M (Person-to-Merchant) UPI transactions has been zero, hence no GST applies.
UPI has grown exponentially, reaching a transaction volume of ₹260.56 lakh crore by March 2025, with India contributing to nearly 49% of global real-time transactions (ACI Worldwide Report 2024).
Case Insensitivity in IRN Generation (Effective June 1, 2025)
To address inconsistencies in invoice numbering during e-invoicing, the Invoice Registration Portal (IRP) will treat invoice/document numbers as case-insensitive starting June 1, 2025.
What This Means
Invoice numbers like “abc123” and “ABC123” will be treated as the same.
All invoice numbers will be automatically converted to uppercase.
This aligns with the case-insensitive treatment in GSTR-1 and helps prevent duplication errors.
Auto-Population of Table 3.2 in GSTR-3B (Effective April 2025)
To ensure data consistency across returns, Table 3.2 of GSTR-3B (pertaining to inter-state supplies to unregistered persons, UIN holders, and composition taxpayers) will now be auto-populated and non-editable.
Compliance Guidance
The values in Table 3.2 will be derived from GSTR-1, GSTR-1A, and IFF filings.
Corrections, if any, must be made in the source returns (GSTR-1 or IFF).
Accurate and timely reporting is essential to avoid filing errors in GSTR-3B.
E-Invoicing and E-Way Bill Compliance Enhancements
E-Invoicing Update
Businesses with an Annual Aggregate Turnover (AATO) of over ₹10 crore are now required to report e-invoices within 30 days from the date of invoice issuance.
Previously, this timeline was applicable only to businesses with AATO above ₹100 crore.
E-Way Bill Validity
E-Way Bill generation is restricted to documents dated within 180 days prior to generation (effective from January 1, 2025).
Extension limits are capped at 360 days from the original generation date.
These measures are designed to tighten control on logistics documentation and ensure timely reporting.
CBIC Guidelines to Streamline GST Registration (Instruction No. 03/2025-GST)
Responding to taxpayer grievances over unwarranted document demands during registration, the Central Board of Indirect Taxes and Customs (CBIC) has issued Instruction No. 03/2025-GST dated April 17, 2025.
Key Directives
Officers must strictly adhere to the prescribed document list in GST REG-01.
No registration notice should be issued based on presumptions or minor discrepancies.
Any request for additional documents must be approved by the Deputy/Assistant Commissioner.
Zonal Chief Commissioners are to implement monitoring systems and issue trade notices for better enforcement.
This directive reinforces transparency, minimizes delays, and promotes ease of doing business.

DISHA Mobile App Launched for Taxpayer Assistance
A new DISHA self-help mobile application has been launched by the CGST & Customs Pune Zone to assist visitors and taxpayers in navigating government offices. This is a user-friendly initiative to enhance in-person taxpayer services.
The April 2025 GST amendments mark a notable shift toward automation, accountability, and taxpayer facilitation. With tighter timelines, improved data integrity, and a more robust registration framework, businesses must now be even more vigilant with accurate return filing and documentation.
Staying updated and proactive will be key to ensuring seamless compliance under the evolving GST regime.
