ICAI Peer Review, explained for a practicing firm.

What is ICAI Peer Review?

Peer Review is the quality assurance mechanism the Institute of Chartered Accountants of India (ICAI) runs over its own members in practice. A practicing firm's assurance engagements — statutory audits and other attest work — are examined by another, independent Chartered Accountant (the "reviewer"), empanelled and allotted by ICAI's Peer Review Board, to check whether the firm's work follows Standards on Auditing, Standards on Quality Control (SQC 1) and other applicable pronouncements.

It exists because a single audit opinion is only as trustworthy as the process behind it. Peer Review looks past the individual engagement to the firm's system — its quality control policies, its documentation discipline, its independence safeguards — and gives regulators, audit committees and the profession itself a basis to trust that system, not just the signature on a report.

Which firms does it apply to?

Peer Review has been rolled out by ICAI in phases, broadly sequenced by the public-interest weight of the entities a firm audits — firms auditing listed companies and larger public-interest entities were brought in first, with the mandatory scope progressively widened to cover more firms doing statutory audit and other attest work, generally referenced against a turnover or engagement-count threshold.

These phase boundaries and thresholds are exactly the kind of detail ICAI revises from time to time. Do not rely on a specific cut-off you read here or elsewhere — check your firm's current applicability directly on the ICAI Peer Review Board portal, or with your regional council, before assuming you are in or out of scope for a given cycle.

The review process, step by step

The mechanics vary in detail by cycle, but the shape of a Peer Review is consistent:

The reviewer's independence from the firm being reviewed is the load-bearing design feature — a firm cannot select its own reviewer, and any prior professional or employment relationship between reviewer and firm is a disqualifying conflict.

Renewal — Peer Review is recurring, not one-time

A Peer Review Certificate is issued for a fixed validity period, after which the firm goes through the process again. This is deliberate: a certificate earned once says nothing about whether the firm's quality control still holds up three years later as staff, clients and engagement mix change. Track your firm's certificate expiry the same way you'd track any other recurring compliance date, and start preparing documentation well before the renewal cycle opens — the exact current validity period should be confirmed on the ICAI Peer Review Board portal, since it has been adjusted before.

Practical notes for a practicing CA

• Documentation is what gets reviewed, not memory. A reviewer works from the file — engagement letters, independence declarations, evidence supporting the opinion (SA 230). If it isn't in the file, it didn't happen as far as the review is concerned.
• Quality control is a firm-level system, not a per-engagement habit. SQC 1 asks for documented policies on acceptance and continuance, engagement performance, monitoring — build these once at the firm level rather than reconstructing them for each review cycle.
• Sample engagements are chosen by the reviewer, not offered by the firm. Keep every attest file — not just the ones you'd proudly show — to the same standard, since you don't control which ones get pulled.
• Treat observations as a heads-up, not a verdict. The reviewer typically discusses findings with the firm before finalising the report — that conversation is your chance to correct a misunderstanding or commit to remediation before it becomes a formal non-compliance note.
• Confirm applicability every cycle, not once. Because ICAI revises the phased thresholds, a firm that was out of mandatory scope last cycle may be in scope this one — check at the start of each financial year rather than relying on last year's answer.

Where TatvaBooks fits

Peer Review doesn't examine your clients' books directly, but the quality of evidence you can produce during an engagement shapes how defensible your files look when they're pulled for review. TatvaBooks keeps an append-only activity log, GST-correct books and Schedule III-ready financial statements for your audit clients — the kind of clean, traceable evidence trail that makes SA 230 documentation easier to stand behind.
