Quick Summary: What Is GSTR-2B and Why Is It Mandatory for Input Tax Credit?
GSTR-2B is an auto-drafted, static ITC statement generated on the 14th of every month. It is critical because Section 16(2)(aa) of the CGST Act legally prohibits taxpayers from claiming ITC on any supplier bill that does not appear in GSTR-2B. Provisional ITC buffers have been removed.
- Legal Mandate: Section 16(2)(aa) requires GSTR-2B reflection for 100% of claimed ITC.
- Static Statement: Generated on the 14th; does not change after monthly crystallization.
- GSTR-2A vs GSTR-2B: 2A is dynamic for vendor tracking; 2B is static for filing GSTR-3B.
- Zero Provisional Buffer: Rule 36(4) provisional credit allowances have been abolished.
1. GSTR-2A vs GSTR-2B Comparison Matrix
Taxpayers must understand the operational differences between dynamic GSTR-2A and static GSTR-2B:
| Comparison Parameter | Form GSTR-2A (Dynamic View) | Form GSTR-2B (Static Statement) |
|---|---|---|
| Nature & Updates | Dynamic & updates continuously as suppliers upload | Static & frozen on the 14th cutoff date |
| Legal Purpose | Continuous vendor filing compliance tracking | Absolute basis for GSTR-3B Table 4 ITC claims |
| Cutoff Window | No cutoff date (real-time stream) | Fixed monthly cutoff (14th of month) |
| Sec 16(2)(aa) Status | Not recognized as statutory claim basis | Statutory gatekeeper for legal ITC |
