10. Consequences of Non-Filing, Penalties & Common Pitfalls

Late Fees & Penalties under Section 47

Failure to file Form GSTR-9 within the prescribed due date incurs a mandatory late fee for every day of default:

Critical Pitfalls to Avoid

1. Filing Without Reconciling GSTR-2B: Claiming excess ITC in GSTR-9 that does not exist in GSTR-2B triggers automated Section 73/74 proceedings.

2. Ignoring DRC-03 for Unpaid Liabilities: Unpaid tax liability declared in Table 4 or Table 9 must be deposited via Form DRC-03 in Cash. You cannot pay short liabilities of GSTR-9 through ITC adjustment.

3. Attempting Revision: GSTR-9 cannot be revised once filed. Extra caution and verification of figures are vital before pressing “File GSTR-9”.
