Audit of Banks: Branch and Statutory Central Audit

Updated 5 October 2026

Bank audit is the statutory audit of a bank's financial statements under the Banking Regulation Act, 1949 and RBI directions. Branch auditors audit selected branches and report to the Central Auditor, who audits head office, consolidates, forms the opinion and submits the LFAR. To solve questions, identify who does what, then apply provision, facts and conclusion.

Understand Audit of Banks: Branch and Statutory Central Audit

A bank is audited differently from an ordinary company because it handles public deposits, is regulated by the RBI, and has thousands of transactions spread over many branches. No single auditor can visit every branch. So the work is split between Statutory Central Auditors (SCAs) and Statutory Branch Auditors (SBAs).

The SCA is appointed for the bank as a whole. In public sector banks, the RBI approves or allocates the SCAs from the panel of firms eligible under its guidelines, and the bank formally appoints them. In private sector banks, the shareholders appoint the auditors at the AGM with the RBI's prior approval. Branch auditors are appointed for specific branches. In public sector banks, the branches to be audited by SBAs are selected by the bank in consultation with the SCAs.

Branch auditors examine the branch's advances, deposits, cash, and other items. They report on the branch's financial statements and give their reports to the SCA. The SCA receives and uses these reports under the statutory scheme: the Banking Regulation Act, 1949, the Companies Act, 2013 (Section 143) as it applies to banking companies, and RBI directions. The SCA reads the reports, decides how to deal with them in the bank audit, and can raise queries. The SCA remains responsible for the opinion on the bank's overall financial statements. The legal basis for using branch auditors' reports is this statutory framework with RBI/ICAI guidance. It is not SA 600 (Revised), which deals with group audits and component auditors.

The Long Form Audit Report (LFAR) is a separate, detailed report required by the RBI. It is not a replacement for the audit report on financial statements. It answers structured questions on areas such as advances, NPA identification, investments, internal controls, and compliance. Branch auditors also complete a branch-level LFAR, which the SCA uses in preparing the bank-level LFAR.

The core exam theme is advances. They are the largest and riskiest asset. You check sanction, documentation, security, end-use, valuation, income recognition, NPA classification and provisioning. A wrong NPA classification overstates income and assets, so it affects the opinion.

Key rules to remember

Role split
SCA = bank-level opinion + consolidation + bank LFAR; SBA = branch audit + branch report/LFAR to SCA
Branch auditors do not give the opinion on the bank as a whole.
NPA test (term loans)
Term loan is an NPA when interest or instalment remains overdue for more than 90 days
Term loans use the 90-day overdue test. Cash credit/overdraft uses the out-of-order test. Agricultural advances use crop-season norms. Check the RBI circular for the facility type.
Out-of-order cash credit/overdraft
A cash credit/overdraft account is out of order if (a) the outstanding balance remains continuously in excess of the sanctioned limit/drawing power, or (b) the balance is within the limit but there are no credits for 90 days, or the credits are not enough to cover the interest debited during the previous 90 days. Such an account is an NPA when it remains out of order for more than 90 days.
Apply the exact RBI wording given in the question. An account that is out of order is not automatically an NPA. It becomes an NPA only when it stays out of order for more than 90 days.
NPA categories
Standard (performing) | NPA categories: Sub-standard → Doubtful → Loss
Standard assets are performing and are not NPAs. Among NPAs, sub-standard: an asset that has been an NPA for a period not exceeding 12 months. Doubtful: an asset that has remained in the sub-standard category for 12 months. Loss: an asset where the loss has been identified by the bank, internal or external auditors, or RBI inspection but the amount has not been written off in full, and the asset is considered uncollectible and of such little value that its continuance as a bankable asset is not warranted, although there may be some salvage or recovery value.
Answer structure
Provision → Facts → Conclusion
State the audit duty or RBI norm, apply it to the facts, then conclude on reporting impact.

How to solve Audit of Banks: Branch and Statutory Central Audit questions

Use this method for any bank audit question, whether on appointment, branch vs central roles, LFAR, or advances.

  1. 1Identify the role in the question: SCA, SBA, or the bank's management.
  2. 2State the governing rule in plain words: RBI directions, Banking Regulation Act or SA principle.
  3. 3List the key facts: branch, account type, overdue period, security, drawing power, timing.
  4. 4Apply the rule to each fact. For NPAs, count the days overdue and note the facility type.
  5. 5Work out the effect: provision shortfall, income reversal, or misclassification.
  6. 6Decide the reporting impact: report to SCA, LFAR comment, modified opinion, or communication to the bank's management or those charged with governance.
  7. 7Write a one-line conclusion that answers exactly what was asked.

Quickest way: Role-Rule-Impact in three lines

When to use it: Use when time is short, for case MCQs or a 5-mark descriptive part.

  1. Role: who is acting, SCA or SBA?
  2. Rule: write the one norm that applies, such as 90 days overdue means NPA for a term loan.
  3. Impact: say what must change and how it is reported, such as reversal of interest, higher provision, or comment in LFAR.
  4. For MCQs, eliminate options that give the SBA the power to give the bank-wide opinion.

Common mistakes in Audit of Banks: Branch and Statutory Central Audit

  • Saying the branch auditor signs the opinion on the whole bank.

    Students confuse branch reports with the bank's overall report.

    Fix: Write that the SBA reports on the branch and the SCA forms the opinion on the bank as a whole.

  • Treating the LFAR as the same as the audit report on financial statements.

    Both are signed by the auditor, so they seem alike.

    Fix: Remember LFAR is a separate detailed RBI-required report. It supplements the audit report and does not replace it.

  • Not counting days properly for NPA classification.

    Students rush and apply 90 days to every facility.

    Fix: Check the facility type first. Term loans use the 90-day overdue test, cash credit/overdraft uses the out-of-order test, and agricultural advances use crop-season norms.

  • Ignoring the SCA's duty to evaluate branch auditors' work.

    Students think relying on a branch report removes responsibility.

    Fix: State that the SCA reads the branch reports, considers their impact, and can raise queries.

  • Stopping at 'classify as NPA' without the consequences.

    Students stop once they identify the category.

    Fix: Add interest reversal, provision required, effect on profit and any LFAR or report comment.

Worked examples

Example 1

A branch of a public sector bank has a term loan where an instalment has been overdue for 100 days. The branch has shown the account as standard and recognised interest income. The branch auditor has noted this in his report to the SCA. Advise how the SCA should deal with this.

Show the solution
  1. Provision: Under RBI prudential norms, a term loan with interest or instalment overdue for more than 90 days is an NPA.
  2. Facts: The instalment is overdue for 100 days, which is more than 90, and the branch still shows the account as standard and recognises interest.
  3. Impact: The account must be classified as NPA. Interest income not actually received must not be recognised and should be reversed. Provision must be made as per the asset category.
  4. Reporting: The SCA considers the branch auditor's report, checks the amount against materiality for the bank as a whole, and asks management to correct the classification. If uncorrected and material, the SCA considers a modified opinion and comments in the LFAR.

Answer: The account is an NPA. Interest income must be reversed and provision made. The SCA evaluates the branch report, asks for correction, and reports in the LFAR or modifies the opinion if material and uncorrected.

Example 2

The SCA of a bank receives reports from branch auditors covering a large share of advances. One branch auditor's report contains a qualification about inadequate security valuation. The SCA wants to issue a clean opinion because the branch is small. Comment.

Show the solution
  1. Provision: The SCA is responsible for the opinion on the bank's financial statements and must evaluate branch auditors' reports, including their effect on the overall statements.
  2. Facts: The qualification relates to security valuation, which affects provisioning on advances. The branch is small, but the bank has many branches, and similar weaknesses may exist elsewhere.
  3. Application: The SCA cannot ignore the qualification just because the branch is small. They must assess the amount, check whether the issue is isolated or common, and quantify the effect on provisions.
  4. Conclusion: If the effect is material to the bank, the SCA should modify the opinion. If it is not material, the SCA should still consider mentioning it in the LFAR.

Answer: The SCA should not issue a clean opinion automatically. They must evaluate the qualification, assess materiality for the bank as a whole, and either modify the opinion or report it in the LFAR depending on the size and pervasiveness.

Exam tips

  • In case-scenario MCQs, first identify the role: SCA or SBA. Many options differ only in who is responsible.
  • For advances questions, always add the consequence: reversal of interest, provision, and reporting.
  • Use the structure provision, facts, conclusion. It earns marks even if one detail is slightly off.
  • Do not quote a circular number or section unless you are sure. State the rule in plain words.
  • When you discuss reliance on branch auditors, base it on the statutory framework: the Banking Regulation Act, 1949, the Companies Act, 2013 (Section 143) as applicable to banking companies, and RBI directions. Do not cite SA 600 (Revised) as the legal basis, because it deals with group audits.

Practice questions from Specialised Areas

Audit of Banks: Branch and Statutory Central Audit: frequently asked questions

What is the difference between a statutory central auditor and a branch auditor?

The central auditor is responsible for the audit of the bank as a whole and gives the overall opinion. The branch auditor audits specific branches and reports to the central auditor. The central auditor evaluates and uses those reports.

What is the LFAR in bank audit?

LFAR is the Long Form Audit Report, a detailed report on specific areas such as advances, investments, controls and compliance, required by the RBI. It is separate from the auditor's report on the financial statements.

Is the 90-day NPA rule the same for all loans?

No. The 90-day overdue test applies to term loans. Cash credit and overdraft accounts have their own out-of-order test, and agricultural advances follow crop-season norms. Always check the facility type in the question.

How should I answer a bank audit NPA question in the exam?

State the RBI norm, apply it to the given facts, and conclude with the effect on income, provision and reporting. Keep it short and structured.
