The GSTN issued an advisory regarding incorrect system-calculated interest auto-populated in Table 5.1 of GSTR-3B for March 2026 relating to the February 2026 period due to a technical glitch. The portal normally auto-calculates interest on delayed filing and carries it forward to the subsequent return period. However, in certain cases, the computation failed to account for the benefit of available cash balance in the Electronic Cash Ledger as per Rule 88B(1) of the CGST Rules, 2017. To address this issue, taxpayers have been provided an option to recompute interest using the “RE-COMPUTE INTEREST” feature in Table 5.1. The revised interest is reflected in the system-generated GSTR-3B PDF. Taxpayers are advised to verify the updated values and manually edit the auto-populated figures accordingly, ensuring that the declared interest is not less than the recomputed amount. The advisory is clarificatory and meant for guidance purposes only.

2. This system computed interest is auto-populated and collected in the Table-5.1 of the subsequent period GSTR-3B. The facility is similar to the collection of late fees for GSTR-3B, which is also calculated after filing of GSTR-3B and collected in subsequent GSTR-3B period.
