GST Audit in Gurugram: GSTR-9C, Annual Return, and Departmental Audit

📌 TL;DR - GST Audit Service in Gurugram Services at a Glance

GSTR-9 (annual return): mandatory for turnover > Rs 2 crore, due 31 December. GSTR-9C (reconciliation): mandatory for > Rs 5 crore, self-certified (CA audit removed from FY 2020-21). Section 65: departmental audit (15-day notice, 3 months). Section 66: special audit (Commissioner-directed, 90+90 days). ITC reconciliation, RCM compliance, and DRC-03 voluntary payment are critical components.

Gurugram businesses need comprehensive GST audit compliance. For a full overview, see our GST Audit national guide.

Component	Threshold	Due Date	Penalty
GSTR-9 (Annual Return)	Turnover > Rs 2 crore	31 December	Rs 200/day (max 0.25% turnover)
GSTR-9C (Reconciliation)	Turnover > Rs 5 crore	31 December	Rs 25,000 (Section 125)
Section 65 (Dept. Audit)	Any registered person	Per notice	Rs 25,000 obstruction
Section 66 (Special Audit)	Commissioner-directed	90+90 days	Per audit findings

Mandatory CA audit under Section 35(5) was removed from FY 2020-21 (Notification 29/2021). Now GSTR-9C is self-certified. However, professional CA preparation is strongly recommended as self-certification carries legal responsibility. Patron handles end-to-end GST audit compliance.

Content is reviewed quarterly for accuracy.
