ICAI Peer Review for CA Firms: What It Checks and How to Prepare

ICAI peer review is not merely a check of whether a CA firm has completed a few standard forms. Under the Peer Review Guidelines, 2022, it is a systematic review of a Practice Unit's systems, procedures and selected assurance-engagement records by an independent Peer Reviewer. The core question is whether the firm's quality framework is appropriate and applied consistently in actual engagements.

What ICAI peer review actually checks

The Guidelines focus on compliance with technical, professional and ethical standards and on whether the Practice Unit has adequate systems and documentation. The review is therefore broader than checking the final audit report.

• Technical and professional compliance: whether assurance work follows applicable standards and professional requirements.
• Ethics and independence: whether relevant ethical and independence matters are identified and addressed.
• Quality of reporting: whether reports are supported by the work performed and conclusions reached.
• Systems and procedures: whether the firm's quality processes operate in practice rather than only in a manual.
• People and infrastructure: whether training, supervision and operating arrangements support quality work.
• Specified practice records: the Guidelines also refer to matters such as the assurance-engagement register and records relating to article and audit assistants.

The ICAI Peer Review Board portal is the best starting point for current forms, announcements and mandate-related material because applicability can change.

Who can come under peer review?

The Guidelines provide several routes into peer review. A Practice Unit may be covered because the Council has made review mandatory for a category, because it applies voluntarily, because a special case is referred, because it is newly established, or because other prescribed criteria apply. Firms should therefore check the live Peer Review Board position rather than relying on an old phase-wise summary.

How the process starts

A Practice Unit seeking peer review submits the prescribed Application-cum-Questionnaire in Form 1. The ICAI Handbook on Peer Review Forms explains the form set and information expected. The standard Form 1 asks for information covering the three preceding financial years, although the relevant review period should be confirmed for the firm's facts and category.

Under the Guidelines, the Board recommends three Peer Reviewers and the Practice Unit selects one. The appointed reviewer plans the review and selects assurance engagements to examine. Sample size can depend on the firm's quality controls, size and nature of practice, methodology, partners, locations and engagement characteristics.

How to prepare before the reviewer selects files

1. Build a complete engagement universe. Keep the assurance-engagement register complete for the review period and reconcile it to practice records. Sampling cannot be reliable if the underlying population is incomplete.
2. Make quality procedures usable. Policies on ethics, independence, acceptance and continuance, engagement performance, consultation, review, human resources and monitoring should reflect how the firm actually works.
3. Make every engagement file traceable. A file should let another professional understand the engagement terms, planning, significant risks, procedures, evidence, important judgments, review trail, conclusions and final reporting.
4. Preserve independence and ethical evidence. Keep declarations, conflict checks, communications and resolution records instead of relying on an oral explanation during the visit.
5. Keep team and training records current. Maintain records showing who worked on engagements, their responsibilities and relevant training or supervision.
6. Prepare all files, not only the best files. The Peer Reviewer selects the sample and may enlarge it. Polishing one showcase file does not cure a systemic weakness.
7. Review reporting quality. Reconcile important conclusions in the working papers to the report issued, especially significant or unusual reporting judgments.
8. Close known quality gaps. If internal monitoring has identified recurring weaknesses, document corrective action and test whether the change operates in later engagements.

What happens during the review?

After selected engagement records are communicated, the Practice Unit is given time under the Guidelines to keep those records ready for the on-site review. The reviewer may expand the sample where circumstances justify it. The review may combine a compliance approach, evaluating whether firm procedures are followed, with a substantive approach examining selected assurance working papers.

The reviewer may consider independence, professional skills and standards, consultation, staffing and administrative arrangements. A strong response is therefore evidence-based: show the policy, show how it operated on the selected engagement and show the review or conclusion that followed.

Worked example: a two-partner CA firm

Suppose a two-partner firm performs statutory audits, tax audits, certifications and some internal-audit work. Before peer review, it should identify which engagements fall within the applicable assurance scope and review period, reconcile the engagement register, organise files consistently, confirm independence documentation, preserve partner and manager review evidence, and update training and assistant records.

If the reviewer selects statutory-audit and certification files, the firm should be able to produce each file without reconstructing the engagement from emails and memory. If several sampled files reveal the same missing review evidence or weak documentation of significant judgments, the reviewer may enlarge the sample. Peer review is therefore a system-quality exercise, not a search for one perfect file.

What happens after the review?

Where the Peer Review Report is unqualified and the Board completes the required processing, a Peer Review Certificate may be issued. The Guidelines state that the certificate is valid for three years, or for another period decided by the Board, with the period running from the date the report is received by the Board. Firms approaching renewal should plan early enough to complete the process before existing validity ends.

If deficiencies lead to a qualified outcome, further action or review may follow under the Guidelines. The productive response is to identify the root cause, correct the firm's system and make the improvement visible in later engagements.

Common preparation mistakes

• Treating peer review as a one-day inspection instead of a review of the firm's operating quality system.
• Submitting Form 1 without reconciling it to the actual engagement population and firm records.
• Having a detailed quality manual but little evidence that procedures were applied on individual engagements.
• Keeping client documents but not documenting professional reasoning, review and conclusions.
• Reconstructing files shortly before the visit instead of maintaining reviewable engagement documentation.
• Assuming the reviewer will examine only a preselected “best” file when the reviewer controls sampling and may enlarge it.

Practical takeaway

A firm is genuinely peer-review ready when its normal files demonstrate how professional standards, ethics, supervision, review and reporting decisions are applied. Start with a complete engagement universe, make quality procedures operational, keep documentation traceable and retain evidence of review and corrective action.
