Impact of Mismatches on ITC Claims

1. ITC Not Reflecting in GSTR-2B

• GSTR-2B is generated based on supplier's GSTR-1 filings.
• If a supplier fails to file GSTR-1 or reports incorrect details, the buyer’s ITC will not appear in GSTR-2B.
• Result: ITC cannot be claimed, leading to cash flow issues.

2. Excess ITC Claimed in GSTR-3B

• If ITC claimed in GSTR-3B is higher than GSTR-2B, it raises red flags.GST Course in Delhi
• GST officers may issue notices under Section 73 or 74 of CGST Act for wrongful claims.
• Result: The taxpayer may face penalties, interest, and demand for reversal of ITC.

3. Underreporting of Sales in GSTR-3B

• If sales reported in GSTR-3B are lower than GSTR-1, it indicates tax underpayment.
• The department may issue audit notices and demand differential tax.
• Result: The recipient's ITC in GSTR-2B may also be impacted, leading to mismatches in reconciliation.

4. Wrong GSTIN in GSTR-1

• If a supplier enters the wrong GSTIN in GSTR-1, the recipient will not see the invoice in GSTR-2B.
• Result: ITC claim is denied, requiring supplier correction in the next return cycle, delaying claims.
