The GST ecosystem continues to evolve with system-driven enhancements aimed at improving compliance and reducing manual errors. Recently, GSTN issued an important advisory regarding the re-computation of interest under Table 5.1 of GSTR-3B, particularly for taxpayers who have noticed discrepancies in system-calculated interest.

Background: System-Based Interest Calculation

To simplify compliance, the GST Portal automatically computes interest on delayed filing of GSTR-3B based on:

• Tax liability discharged
• Break-up of liability reported in the return

Issue: Incorrect Interest Computation for Feb 2026

GSTN has identified a technical glitch affecting some taxpayers for the February 2026 period, wherein:

• Interest reflected in March 2026 GSTR-3B may have been incorrectly calculated
• The system did not consider the minimum balance available in the Electronic Cash Ledger as per Rule 88B(1)

Solution: “Re-compute Interest” Facility

To address this issue, GSTN has enabled a corrective feature:

• Re-compute Interest Button
• Available under Table 5.1 of GSTR-3B
• On clicking, the system recalculates interest using updated parameters and reflects the corrected values in the system-generated PDF
