GSTR-9C is a reconciliation statement that taxpayers are required to file, wherever applicable, along with their Annual Return (GSTR-9). It helps reconcile the turnover, tax paid and other details reported in the Annual Return with the figures reflected in the audited financial statements or books of accounts.
The purpose of GSTR-9C is to ensure consistency between GST returns and financial records and to identify any differences that may require clarification or adjustments.
