GST Compliance Changes Effective October 1, 2025: Tightening ITC and Credit Note Rules
The government has rolled out significant compliance changes under GST 2.0, effective October 1, 2025, to enhance transparency, curb fake invoicing, and streamline credit utilization. The updates to the Central Goods and Services Tax (CGST) Act mark a major shift in how businesses manage Input Tax Credit (ITC) and credit notes.
Key Compliance Updates
1. Amendment to Section 38 of the CGST Act
The amended provision mandates that Input Tax Credit (ITC) will be available only on accepted invoices that appear in GSTR-2B (now termed the Statement).
Any rejected invoices will no longer be eligible for ITC claims.
Businesses are required to reconcile invoices through the IMS-mediated portal to ensure accuracy and prevent mismatches.
2. New Rules for Credit Notes
The GST Council has introduced a mandatory ITC reversal mechanism for all registered recipients when a credit note is issued by suppliers.
This ensures that no excess credit remains claimed once a transaction is adjusted.
The move is aimed at improving reporting integrity and reducing refund disputes.
3. Simplified Compliance under GST 2.0
The new compliance system integrates auto-matching, real-time validations, and AI-based anomaly detection, easing manual reconciliations for MSMEs while tightening fraud controls for high-value transactions.
GST Revenue Performance: September 2025
India’s GST collections for September 2025 stood at ₹1.89 lakh crore, reflecting the early impact of the simplified GST rate structure implemented from September 22, 2025.
The revenue growth is attributed to improved compliance, broader tax base coverage, and stronger e-invoicing adoption.
The finance ministry expects sustained monthly collections above ₹1.85 lakh crore in Q4 FY25, driven by festive consumption and policy stability.
Conclusion
The October 2025 GST compliance changes mark a pivotal shift toward greater accountability in tax reporting. By linking ITC strictly to verified invoices and enforcing timely reversals on credit notes, the government aims to create a cleaner, technology-driven GST regime. For businesses, staying compliant will require real-time reconciliation, precise invoice validation, and timely credit management to avoid penalties and ensure smooth filings.
