GST Audit Services for Delhi Businesses

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

GST audit in Delhi encompasses three streams: (1) GSTR-9C self-certified reconciliation for turnover above Rs 5 crore, (2) departmental audit under Section 65 by GST Commissionerate Delhi, and (3) special audit under Section 66 ordered during investigation. Since Finance Act 2021 removed mandatory CA certification, GSTR-9C is self-certified - increasing both taxpayer responsibility and departmental scrutiny. Patron's Delhi CA team provides end-to-end GST audit covering GSTR-9/9C preparation, ITC reconciliation, Section 65 representation and demand prevention.

Delhi has one of India's largest concentrations of GST-registered businesses - wholesale traders in Chandni Chowk, IT companies in Nehru Place, manufacturers in Okhla and corporates at Connaught Place managing multi-state operations. Delhi businesses frequently operate with multiple GSTINs across NCR (Delhi, Haryana, UP), creating unique aggregate turnover and multi-GSTIN GSTR-9C challenges.

What is GST Audit?

GST audit is the examination of records, returns and documents maintained by a GST-registered person to verify correctness of turnover declared, taxes paid, input tax credit availed and refunds claimed (Section 2(13), CGST Act 2017).

Three streams: (1) GSTR-9C - self-certified reconciliation statement reconciling GSTR-9 with audited financials, mandatory for turnover > Rs 5 crore; (2) Section 65 departmental audit - conducted by CGST/DGST officers at taxpayer's premises, any registered person; (3) Section 66 special audit - directed by Commissioner during investigation.

For Delhi's trading firms in Chandni Chowk, manufacturers in Okhla and IT companies in Nehru Place, GSTR-9C reconciliation identifies mismatches between returns and books before the department does.

Since Finance Act 2021 removed mandatory CA certification, GSTR-9C is self-certified - but professional preparation remains essential for accuracy.

Key Terms for GST Audit in Delhi:

GSTR-9: Annual return consolidating all GSTR-1 and GSTR-3B data. Mandatory for turnover > Rs 2 crore.

GSTR-9C: Self-certified reconciliation statement between GSTR-9 and audited financials. Mandatory for turnover > Rs 5 crore.

Section 65: Departmental audit by CGST/DGST officers at taxpayer's premises. Any taxpayer, any time.

Section 66: Special audit ordered by Commissioner during investigation.

DRC-03: Voluntary payment of short-paid tax to prevent demand proceedings.

Aggregate Turnover: PAN-level, all-India computation including all GSTINs.

Who Needs GST Audit Services in Delhi?

  • Turnover > Rs 5 Crore (GSTR-9C Mandatory): Wholesale traders in Chandni Chowk, manufacturers in Okhla, IT companies in Nehru Place, corporates at Connaught Place. Multi-GSTIN NCR businesses require separate GSTR-9C per GSTIN.
  • Turnover > Rs 2 Crore (GSTR-9 Mandatory): Delhi businesses between Rs 2-5 crore must file GSTR-9. Reconciliation workpapers advisable for S.65 audit defence.
  • ADT-01 Notice Recipients (S.65 Audit): Any Delhi business can receive departmental audit notice regardless of turnover. Increased since GSTR-9C self-certification.
  • Businesses Under Investigation (S.66): If DGGI Delhi or anti-evasion units suspect wrong ITC or incorrect value, Commissioner orders special CA audit.
  • Multi-GSTIN Delhi NCR Businesses: GSTINs in Delhi + Haryana (Gurugram) + UP (Noida) - separate GSTR-9/9C per GSTIN with PAN-level aggregate computation.

GST audit ab mandatory nahi hai kya? CA se audit mandatory nahi hai FY 2020-21 se. Lekin Rs 5 crore se zyada turnover par GSTR-9C self-certified file karna zaroori hai. S.65 audit kisi bhi taxpayer par ho sakta hai.

GSTR-9C kab tak file karna hai? 31 December - financial year ke baad.

Multi-GSTIN hai toh? Har GSTIN ka alag GSTR-9 aur 9C file karna padega. Aggregate turnover PAN level par calculate hota hai.

Don't Miss the 31 December GSTR-9C Deadline

Missing the GSTR-9C deadline exposes your business to Rs 25,000 penalty and increased risk of Section 65 departmental audit. GSTR-9C is your opportunity to identify and correct discrepancies through DRC-03 before the department finds them.
