Common questions

FAQs.

Why reconcile GSTR-1, GSTR-3B and the books?
The same sales are reported three times. A gap between them is the first thing an officer or an auditor looks for.
What causes common differences?
Timing, credit notes, amendments, advances, exports and inputs claimed in a later month. Record each reason and the action.
Is this the annual return reconciliation?
No. It is a monthly working paper that supports the annual return and its reconciliation statement. Use our GSTR-9 and 9C tools for those.
