Quick Answer: How to Reconcile GSTR-2A/2B with GSTR-3B & Handle Ineligible ITC?
To prevent tax demand notices, match your purchase register against GSTR-2B for monthly claims and GSTR-2A for historical supplier filing status. Segregate blocked ITC under Section 17(5) into Table 4B(1) of GSTR-3B, and ensure all eligible credit claims strictly comply with the November 30th annual time-bar limit under Section 16(4).
- GSTR-2B is static and serves as the legal basis for claiming ITC in GSTR-3B Table 4A.
- Section 16(4) imposes a mandatory cutoff of November 30 following the fiscal year.
- Ineligible credits (Section 17(5)) claimed erroneously incur 18% interest p.a. upon reversal.

2. Section 16(4) Mandatory Statutory Time-Bar Limits
Under Section 16(4) of the CGST Act, taxpayers cannot claim Input Tax Credit on any invoice or debit note past **November 30th** following the end of the financial year.
- Strict Substantive Condition: High Courts have consistently ruled that Section 16(4) is a non-negotiable statutory condition.
- Interest Penalties: Claiming backdated credit past November 30 triggers automatic DRC-01 notices with mandatory 18% annual interest.
