# Section 16(2)(aa) CGST Act Explained: Legal Rules for ITC
Section 16(2)(aa) was introduced to eliminate provisional Input Tax Credit claims. It establishes that **no taxpayer shall be entitled to ITC** unless the details of the invoice or debit note have been communicated to the recipient in GSTR-2B.
## Key Statutory Requirements under Sec 16(2)(aa)
1. **Supplier Filing Mandatory:** Supplier must file GSTR-1 or use the Invoice Furnishing Facility (IFF).
2. **Communication in GSTR-2B:** Invoice must reflect in the generated GSTR-2B of the corresponding period.
3. **No Relaxation for Good Faith Purchases:** Even if you paid the vendor in full including GST, credit is denied if the vendor fails to file.
## Legal Safeguards for Buyers
- Include GST filing clause in supplier contracts.
- Retain monthly GSTR-2B matching audit logs generated by GSTMatch.
- Issue formal notice to non-filing vendors referencing Sec 16(2)(aa).
