The Finance Bill 2025-26 likely to be introduced in the budget session of Parliament is expected to amend the Goods and Services (GST) Act. The amendment will incorporate the Invoice Management System (IMS) into the legal framework. Sources told Moneycontrol that the amendment aims to address revenue losses caused by fake invoicing and to eliminate tax evasion. IMS was introduced as a new feature on the GST portal in November 2024, allowing taxpayers to track invoices in real time to see which are paid and the ones pending. It was introduced to reduce errors and with the intent to reduce notices issued on account of input tax credit (ITC) mismatch in returns. The system, according to the official, has been getting an enthusiastic response. IMS continues to be optional and will remain so after the amendment to the GST Act.
“IMS as of now is not in the rule books. This amendment will bring it into the GST Act. Adding IMS without amending the GST law to support its implementation had raised doubts about its legal foundation,” a senior government official told Moneycontrol.
A solution to fake invoicing?
Filing counterfeit invoices has been a persistent issue in the GST framework. The government hopes that IMS will ensure automatic reflection of invoices in GST returns, enabling real-time cross-verification of supplier and recipient data. This feature will prevent fraudulent ITC claims and flag discrepancies before they result in revenue leakage, sources say.
“IMS will actually nip fake invoicing in the bud. We will not suffer revenue loss,” the official cited earlier added.
The 55th GST Council meeting recommended amending the CGST Act and Rules to integrate IMS. The proposed changes aim to provide a legal basis for the generation of FORM GSTR-2B and improve ITC.
The government hopes that under IMS, invoices will automatically populate relevant GST returns, ensuring seamless integration with the compliance mechanism. The system will also identify mismatches or errors instantly, reducing the need for reconciliation and amendments in subsequent returns.
