The time limit for availing input tax credit for a financial year has been extended. Earlier, it was the due date for filing the GSTR-3B return for September or the date of filing the relevant annual return, whichever was earlier. Now, it has been extended to 30th November following the end of the financial year or the date of filing the relevant annual return, whichever is earlier.

A new condition has been introduced for availing input tax credit. The input tax credit reflected in GSTR-2B should not be restricted as per the provisions covered under section 38. Section 38 specifies situations where input tax credit availment will be restricted, based on defaults committed by the supplier of goods or services.
Input tax credit availment will be restricted in the following situations: (1) Supply by a newly registered person within a specified period, (2) Supplier has defaulted in tax payment for a prescribed period, (3) Output tax payable in GSTR-1 exceeds the actual output tax paid in GSTR-3B by the supplier, (4) Supplier has availed more input tax credit in GSTR-3B than reflected in GSTR-2B, (5) Supplier has defaulted in discharging tax liability under section 49(12), and (6) Supplier falls under a prescribed class of persons.
These changes have been introduced to streamline the input tax credit system, enhance compliance, and prevent potential misuse or fraudulent practices. By extending time limits and introducing restrictions based on supplier defaults, the government aims to ensure a more transparent and efficient GST regime.
These changes will have a significant impact on businesses, especially those with an aggregate turnover exceeding INR 10 crores, as they will now be mandated to generate e-invoices. Additionally, the new conditions and restrictions on input tax credit availment will require businesses to closely monitor their suppliers' compliance and ensure timely rectification of errors or omissions in various returns and statements.
