The GST compliance framework in 2026 continues to evolve with stricter ITC matching norms, updated e-invoicing requirements, and the GSTR-9 annual return deadline for FY 2025-26. This article summarises the key GST updates that every registered taxpayer must act upon.
GST in 2026 — The Compliance Landscape
The Goods and Services Tax framework has undergone continuous refinements since its introduction in 2017. For registered taxpayers, 2026 brings stricter Input Tax Credit (ITC) matching requirements, expanded e-invoicing applicability, and important filings related to FY 2025-26.
Mandatory 100% ITC Matching with GSTR-2B
With effect from the mandatory implementation dates notified by the GSTN, provisional ITC under Rule 36(4) has been eliminated. Input Tax Credit is now available strictly on the basis of reflection in GSTR-2B (auto-drafted ITC statement). The critical compliance requirements are:
- ITC is eligible only if reflected in the auto-drafted GSTR-2B for the relevant month.
- Taxpayers must rigorously follow up with their suppliers to ensure timely filing of GSTR-1, which flows into GSTR-2B.
- Purchases not reflected in GSTR-2B cannot be claimed, even if the physical invoice is in hand.
- Monthly reconciliation between purchase records and GSTR-2B is essential before filing GSTR-3B.
E-Invoicing — Current Applicability
E-invoicing under GST is mandatory for all registered businesses with an aggregate annual turnover exceeding ₹5 crore in any preceding financial year. Key features:
- E-invoices are generated on the Invoice Registration Portal (IRP) and assigned a unique Invoice Reference Number (IRN).
- The data from e-invoices auto-populates into GSTR-1, reducing manual reporting errors.
- Invoices issued without IRN for applicable taxpayers are treated as invalid and ITC on such invoices is ineligible.
- Businesses approaching the ₹5 crore threshold must ensure their billing systems are IRP-integrated in advance.
GSTR-1A — Amendment Facility Before GSTR-3B
The GSTR-1A facility, which allows amendment of GSTR-1 data before the filing of GSTR-3B, is now operational. This provides a significant compliance relief for correcting invoice-level errors without the need for amendments in subsequent returns.
Rule 42/43 ITC Reversal — Annual True-Up
For taxpayers making both taxable and exempt supplies, ITC reversal under Rule 42 (inputs) and Rule 43 (capital goods) must be computed on a monthly basis and reported in GSTR-3B. An annual true-up is required in the September return of the following financial year. Taxpayers must compute the final reversal for FY 2025-26 and report it in the September 2026 GSTR-3B.
GSTR-9 and GSTR-9C for FY 2025-26
The Annual GST Return (GSTR-9) and Reconciliation Statement (GSTR-9C) for Financial Year 2025-26 are due by 31 December 2026.
| Form | Applicability | Due Date |
|---|---|---|
| GSTR-9 | All registered taxpayers with turnover above ₹2 crore | 31 December 2026 |
| GSTR-9C (Self-Certified) | Taxpayers with turnover above ₹5 crore | 31 December 2026 |
GST Rate Rationalization — Key Updates
- Life and Health Insurance: Discussions on GST reduction on pure term life insurance premiums and health insurance are ongoing.
- Restaurant Services: GST at 5% (without ITC) continues for standalone restaurants. Hotels with declared room tariff above ₹7,500 per night attract 18% GST with ITC on restaurant services.
- Online Gaming: The 28% GST levy on the full face value of bets/deposits for online gaming continues.
