March is a notoriously heavy month for finance teams. To add to your checklist, the GST department has just rolled out several updates you need to act on before the financial year closes.
Latest GST Changes
- GSTR-3B Liability Breakup: From the February 2026 tax period, the GST portal now auto-populates the "Tax Liability Breakup" for any past dues paid in the current return. This adds an extra validation check before submission.
- Upcoming Financial Year Deadlines: If you plan to opt for the Composition Scheme (Form CMP-02) or need to submit a Letter of Undertaking (LUT) for zero-rated exports for the 2026 to 2027 financial year, the strict deadline is 31 March 2026.
- Portal Consolidation: The "Additional Notices and Orders" tab has been merged into the main "Notices and Orders" section. You no longer need to check two separate tabs for department communications.
- Appeals and Refunds: The GSTAT has issued new guidelines specifying mandatory documents for filing appeals. Additionally, provisional refunds now cover claims arising from an inverted duty structure.
The Practical Impact
The government is tightening system-driven calculations to minimise reporting errors. The auto-populated fields in GSTR-3B mean your reconciliation processes must be spotless. Furthermore, missing the 31 March deadlines for your LUT or the Composition Scheme will directly impact your cash flow and tax rates for the entire next year.
