Any mismatch between GSTR-3B, sales records, ITC claims, or tax payments reflected in bank statements can trigger notices, interest, or ITC reversals. Discrepancies between your books and your GST returns can lead to severe tax liabilities.
This comprehensive guide covers common mismatches between GSTR-3B and books of accounts and how to fix them.
Why GSTR-3B Reconciliation Is Important
Compliance Requirement
Reconcile the turnover and output liability in your GST returns with your books of accounts. Perform a two-way reconciliation: check your books against GSTR-3B, and GSTR-3B against GSTR-2A.
Consequences of Mismatches
GST mismatches lead to loss of ITC, penalties, notices, and blocked credit.
