Process
How the service works
The workflow is built to be predictable: document collection, legal review, filing, and post-filing follow-through.
Confirm the audit trigger
We confirm which audits apply — statutory under s.143 (every company), tax under s.44AB (threshold), internal under s.138 — and the relevant financial year.
Collect the evidence pack
We pull the trial balance, ledgers, bank statements, confirmations, and statutory registers, and flag gaps before fieldwork starts.
Run the audit fieldwork
We perform the audit procedures to ICAI Standards on Auditing — vouching, verification, analytical review, and management representation.
Draft the report and UDIN
We finalise the audit report, generate the UDIN for the signing CA, and present findings to the board with a management letter.
File with ROC and IT
We support the connected filings — AOC-4 within 30 days of the AGM, MGT-7 within 60 days, and Form 3CA/3CB with the ITR.
AEO summary
Audit & assurance covers the audits a Private Limited company must get: statutory audit under s.143 Companies Act 2013 (every company), tax audit under s.44AB Income-tax Act 1961 (turnover above the threshold), internal audit under s.138 for larger companies, and BRSR assurance where applicable. Reports are filed via AOC-4/MGT-7, with the audit done before the AGM deadline.
The four audits and when each one applies
Statutory audit applies to every company without exception — s.143 of the Companies Act 2013 read with s.139 (appointment) requires the accounts to be audited before the AGM. Tax audit applies from the s.44AB turnover threshold (₹1 crore, ₹10 crore for ≤ 5% cash) and feeds the ITR through Form 3CA/3CB + 3CD. Internal audit under s.138 applies to every listed company and to other companies above the Rule 13 thresholds (paid-up capital ₹50 crore, turnover ₹200 crore, or outstanding loans/borrowings ₹100 crore). BRSR assurance applies to listed entities under SEBI LODR.
The audit calendar is fixed: the statutory audit finishes before the AGM (30 September for a March year-end), AOC-4 is filed within 30 days of the AGM, MGT-7 within 60 days, and the tax audit report by 30 September for the ITR. Missing any one of these deadlines cascades into the others.
- • Statutory — s.143, every company, before the AGM
- • Tax — s.44AB, turnover > ₹1 crore (business) / ₹50 lakh (professional); ₹10 crore for ≤ 5% cash
- • Internal — s.138 + Rule 13: capital ≥ ₹50 Cr, turnover ≥ ₹200 Cr, borrowings ≥ ₹100 Cr
- • BRSR — SEBI LODR Reg 34(2)(f), listed + phased BRSR-Core assurance
- • Filing clock — AOC-4 in 30 days of AGM, MGT-7 in 60 days, ₹100/day s.403 late fee
Why audit timing is a filing deadline, not a formality
The audit is the gating item for the entire ROC calendar. The board cannot approve the financial statements credibly without the auditor's report, the AGM cannot be held without board-approved financials, and AOC-4 cannot be filed without the AGM. A company that starts its audit in October has already missed the September AGM window, and the ₹100/day s.403 fee plus the s.137(3) penalty (₹1,000/day, cap ₹10 lakh) start running on AOC-4 immediately.
The fix is starting the evidence pack early. When the trial balance, ledgers, bank statements and statutory registers are audit-ready by August, the fieldwork is a formality and the report lands before the AGM date — with the UDIN in place so the ROC, banks and the income-tax department all accept it on sight.
- • Gating order — audit → board approval → AGM → AOC-4 (30 days) → MGT-7 (60 days)
- • Late AOC-4 — ₹100/day (s.403) + ₹10,000 + ₹100/day penalty (s.137(3), max ₹2,00,000)
- • Tax audit report — Form 3CA/3CB + 3CD by 30 September
- • Every report UDIN-verified on the ICAI portal

Timeline

Audit fees are quoted on turnover, transactions, and evidence-pack readiness — not a portal fee.
