Accounting for Banks: The Complete 2026 Guide for the IIBF Bank Promotions Exam

Accounting for banks is the single most decisive topic in the IIBF Bank Promotions exam. And this 2026 guide breaks it down from first principles to exam-ready mastery. If you have ever stared at a bank balance sheet.

Wondered why deposits sit on the liabilities side. This is the only explainer you will need. We cover the regulatory framework.

Financial statements. NPA classification. Provisioning, income recognition, journal entries, IRAC norms and a proven study plan.

Most candidates lose marks here not because the subject is hard. But because nobody ever explained it in plain language. By the end of this guide.

Bank accounting will feel less like a maze. More like a checklist you can rank. Revise and reproduce in the exam hall.

What Is Accounting for Banks?

Accounting for banks is the specialised discipline of recording. Classifying, summarising and reporting a bank's financial transactions. It differs sharply from ordinary business accounting. A bank does not buy and sell goods. Its core business is financial intermediation.

A bank accepts deposits from savers and lends those funds to borrowers. It earns the spread between the interest it pays. The interest it charges.

Because every rupee on the books belongs partly to the public. Bank accounting runs on stricter rules. Tighter internal controls and constant regulatory supervision.

In the IIBF Bank Promotions exam. This topic blends three things at once: pure theory. Practical banking know-how and regulatory understanding. That is exactly why it carries weight. Why it rewards candidates who prepare it properly.

Why Bank Accounting Matters for Your Career and Your Exam

Strong command of accounting for banks pays off twice. First, it directly lifts your score. Second, it makes you better at the job.

Loan monitoring. Internal audit. Compliance.

Financial control and regulatory reporting all sit on top of accounting fundamentals.

Examiners love this area because it cannot be crammed blindly. You have to understand the logic. Once you grasp why an entry is passed. You can answer almost any twist the question paper throws at you. That conceptual edge is what separates a pass from a rank.

Regulatory Framework Governing Bank Accounting in India

Bank accounting in India is not controlled by one single law. It rests on a layered framework of authorities and standards. Every aspirant should be able to list these from memory. Because questions often test this directly or indirectly.

• Reserve Bank of India (RBI) guidelines and master directions
• Banking Regulation Act, 1949
• Companies Act, where applicable for disclosure and reporting
• Applicable Accounting Standards and Ind AS norms
• Prudential norms on income recognition, asset classification and provisioning

The RBI sits at the centre of this structure. It prescribes the format. The prudential treatment and the supervisory expectations for banking accounts.

Because banks hold public deposits, the RBI cares about more than profit. It cares about safety, transparency and systemic stability. Always confirm the exact wording on the latest official IIBF notification.

Current RBI master directions.

Why Bank Accounting Is Different From General Accounting

A bank is structurally unlike a trading or manufacturing firm. A normal business buys goods and sells them. A bank treats money itself as its commodity. It mobilises deposits and deploys funds into loans, advances and investments.

This produces several unique accounting features:

• Deposits are liabilities, because the bank must repay them.
• Loans and advances are assets, because they generate income.
• Interest income and interest expense drive profitability.
• Risk assessment is built into the accounting treatment itself.
• Provisioning and asset classification directly reduce or protect profit.

This is where beginners stumble. Many ask why deposits appear on the liabilities side. The answer is simple: deposit money belongs to the customer. Not the bank.

Bank Accounting vs General Business Accounting

Read this table as a story, not a list. It shows how a bank manages money. Risk and compliance at the same time. That mindset will help you reason through any case-based question.

Financial Statements of a Bank

Two statements dominate accounting for banks: the Balance Sheet. The Profit and Loss Account. Together they reveal a bank's financial position and its operating performance.

Balance Sheet of a Bank

The balance sheet captures the bank's position on a single date. One side shows where the money came from. The other shows where it went.

Liabilities side (sources of funds):

• Capital: share capital contributed by shareholders
• Reserves and Surplus: statutory reserves, revenue reserves, capital reserves, retained earnings
• Deposits: demand deposits, savings deposits, term deposits
• Borrowings: from RBI, other banks and financial institutions
• Other Liabilities and Provisions: bills payable, accrued expenses, provisions and miscellaneous items

Assets side (uses of funds):

• Cash and Balances with RBI: cash in hand and mandatory reserves
• Balances with Banks. Money at Call and Short Notice: interbank placements and liquid positions
• Investments: government securities, bonds and approved investments
• Advances: loans, cash credit, overdraft, bills purchased and discounted
• Fixed Assets: premises, furniture and equipment
• Other Assets: accrued income, stationery and deferred tax assets where applicable

Remember the headline: in bank accounting. Advances and investments are usually the largest assets. While deposits are the largest liability.

Profit and Loss Account of a Bank

The Profit and Loss Account shows the operating result over a period. It explains what the bank earned and what it spent.

Major income items:

• Interest Earned: interest on advances, investments and balances with banks
• Other Income: commission, exchange, brokerage, locker rent, service charges and treasury gains

Major expenditure items:

• Interest Expended: interest paid on savings accounts, term deposits and borrowings
• Operating Expenses: salaries, rent, electricity, technology, printing and communication
• Provisions and Contingencies: provision for NPAs. Depreciation, standard asset provision and tax-related provisions

Here is the exam trap to internalise: profitability in banking is not just gross interest income. Provisions, contingencies and recognition norms can swing the bottom line dramatically.

Core Accounting Concepts Used in Banking

Four classical concepts sit beneath every banking entry. Know them cold.

Accrual Concept

Income and expenses are recognised when earned or incurred. Not necessarily when cash moves. For standard assets, interest is normally recognised on an accrual basis.

Prudence Concept

Prudence means anticipating likely losses and providing for them in advance. In banking this is critical. A bank must never overstate income or assets.

Once a loan turns irregular or doubtful. The bank stops recognising unrealised income. Creates a provision as per norms.

Matching Concept

Expenses of a period are matched against the income of the same period. This keeps reported profit honest.

Consistency Concept

The same accounting policies are applied period after period. Unless a change is justified by regulation or by better reporting.

Interest Recognition in Banks

Income recognition is one of the most heavily tested corners of bank accounting. The whole game turns on whether the asset is standard or non-performing.

For Standard Assets

Interest is recognised on an accrual basis. The bank books interest as income even before it physically receives the cash. Provided the account is performing regularly.

For Non-Performing Assets

Once an asset becomes an NPA. Unrealised interest can no longer be treated as accrual income. It must be recognised only on a cash basis. This single rule prevents banks from inflating profits with income they may never collect.

Non-Performing Assets (NPA) and Their Accounting Significance

A Non-Performing Asset is a loan or advance where the borrower fails to meet repayment obligations within the prescribed time. NPA status ripples through income recognition, provisioning, profitability and balance sheet quality.

The 90-Day NPA Threshold

As a general rule. A loan account becomes an NPA when interest or a principal installment stays overdue for more than 90 days. Specific products and segments can differ. So confirm the exact treatment on the latest official IIBF notification. Current RBI directions.

Categories of Assets

The slide from standard to substandard to doubtful to loss is not just a label change. At every step, the required provision rises and reported profit can fall.

Provisioning Norms in Bank Accounting

Provisioning means setting aside an amount out of profit to absorb expected losses from bad or doubtful assets. It is the heart of prudent bank accounting.

Do not confuse a provision with a write-off. A provision is an anticipated charge against profit. A write-off removes the asset value from the books to the extent considered irrecoverable.

Indicative Provisioning Structure

Exact provisioning percentages vary by sector. Security coverage, unsecured exposure and updated prudential directions. Always verify the current figures on the latest official IIBF notification. For the exam, lock in the principle: higher risk means higher provisioning.

Loan Accounting and Important Journal Entries

Loans are a bank's main earning assets, so loan accounting is foundational. These entries touch both the balance sheet. The profit and loss account. Learn the logic, and the entries write themselves.

Loan Disbursement Entry

Loan Account Dr.   To Customer Account

This records the creation of the loan asset. Credits the borrower's account.

Interest Accrual Entry

Interest Receivable Account Dr.   To Interest Income Account

This records interest earned but not yet received. Provided the asset is standard.

Interest Received Entry

Cash / Bank Account Dr.   To Interest Receivable Account

This records the actual realisation of accrued interest.

Interest on Deposit Accounts

Interest Expense Account Dr.   To Customer Deposit Account

This reflects the bank's obligation to pay interest to depositors.

NPA-Related Reversal Concept

If interest was already booked on accrual. The account later turns NPA. The unrealised income may need to be reversed under prudential treatment. This stops profit from being overstated.

Deposit Accounting in Banks

Deposits are the primary fuel for lending. From the bank's side. Every deposit is a liability, because the bank must repay the depositor.

Savings Bank Account

Savings accounts generally carry interest. It is computed periodically. Credited at defined intervals as per policy and applicable instructions.

Current Account

Current accounts generally do not carry interest. They suit businesses and customers who need high transaction volumes. Liquidity and operational convenience.

Term Deposit

Term deposits are accepted for a fixed period at a specified rate. They are a liability payable on maturity. Or on premature closure subject to rules.

Core Banking System (CBS) and Its Impact on Accounting

The Core Banking System. Or CBS. Has reshaped bank accounting from a branch-level manual process into a centralised. Real-time, technology-driven model.

Features of CBS in Accounting

• Real-time posting of transactions
• Centralised ledger maintenance
• Uniform accounting treatment across all branches
• Automatic generation of reports and statements
• Stronger control, audit trail and reconciliation

Benefits of CBS

• Fewer manual errors
• Better transaction monitoring
• Instant customer access across branches
• Faster balancing and reporting
• Improved compliance and operational control

For the exam, see CBS as more than software. It directly upgrades accounting quality, speed, transparency and financial control.

Bank Reconciliation Statement in the Banking Context

A Bank Reconciliation Statement reconciles the difference between the balance in the cash book or bank book. The balance in the passbook or bank statement. Though it is a general concept. It remains relevant in banking operations and exams.

Common Causes of Difference

• Cheques issued but not yet presented for payment
• Cheques deposited but not yet cleared
• Bank charges debited by the bank. Not yet recorded in the books
• Interest credited by the bank but not yet recorded in the books
• Direct deposits or standing instructions
• Errors or omissions

Reconciliation safeguards the reliability of the books. It helps detect errors, delays, omissions and unauthorised entries early.

IRAC Norms in Bank Accounting

IRAC stands for Income Recognition and Asset Classification. These norms are among the most important pillars of banking accounting. Supervision.

IRAC norms decide:

• When income can be recognised
• When an account becomes an NPA
• How the asset is classified
• How much provision is required

The anchor figure to remember is the 90-days-overdue norm for general NPA recognition in many standard lending cases. Once an asset slips into NPA. The accounting treatment changes across the board.

Advanced Concepts Linked to Accounting for Banks

Cash Reserve Ratio (CRR)

The Cash Reserve Ratio is the portion of a bank's net demand. Time liabilities that must be kept with the RBI in cash. It shapes liquidity management and the presentation of balances with the RBI. Confirm the current rate on the latest RBI notification.

Statutory Liquidity Ratio (SLR)

The Statutory Liquidity Ratio is the minimum proportion of net demand. Time liabilities a bank must hold in specified liquid assets. Mainly government securities, cash and approved instruments. It connects directly to the investment portfolio.

Contingent Liabilities

Items such as letters of credit. Guarantees and acceptances may not appear as funded assets. Yet they create potential obligations. They matter for disclosure and risk.

Off-Balance Sheet Items

Off-balance sheet items are central to modern banking. They may not show up as normal assets or liabilities. But they carry risk and require disclosure. Monitoring and often capital or provisioning treatment under regulation.

How to Study Accounting for Banks and Actually Score

This subject feels technical at first. Arrange it systematically and it becomes one of the most scoring. Predictable areas on the paper. Use this five-step routine.

1. Understand the banking structure first. Start with the nature of banking. Nail down why deposits are liabilities and loans are assets.
2. Learn the Balance Sheet and P&L format. Study each major head and connect it to real banking operations.
3. Go deep on NPA and provisioning. Master the categories, the 90-day threshold and the broad provisioning logic.
4. Practise the accounting entries. Even when entries are not asked directly, they cement conceptual clarity.
5. Revise through notes and tests. Use short notes and charts for recall, then pressure-test yourself on mock tests with timed practice.

Pair this routine with our free guides for chapter-wise notes and quick revision sheets.

Common Mistakes to Avoid

Sidestep these errors and you instantly outperform most candidates:

• Treating deposits as assets. They are liabilities, full stop.
• Booking NPA interest on accrual. Once an asset is an NPA, income is cash basis only.
• Confusing provision with write-off. A provision is a charge against profit. A write-off removes the asset value.
• Memorising provisioning percentages blindly. They change. Learn the logic. Confirm current figures on the latest official IIBF notification.
• Ignoring off-balance sheet items. They carry real risk and are frequently tested.
• Skipping journal entries. Even basic entries reveal the concept behind every statement head.

Frequently Asked Questions

What is the 90-day rule for NPA classification in bank accounting?

A loan or advance generally becomes a Non-Performing Asset when interest or a principal installment stays overdue for more than 90 days. This shifts income recognition from accrual to cash basis and triggers provisioning. Confirm product-specific rules on the latest official IIBF notification.

Why are bank deposits shown on the liabilities side of the balance sheet?

Deposits are the bank's obligation to repay the depositor. The money belongs to the customer. Not the bank, so deposits are correctly classified as liabilities. This is one of the most fundamental ideas in accounting for banks.

What does IRAC stand for and why is it important?

IRAC stands for Income Recognition and Asset Classification. These RBI norms decide when a bank can recognise income. When an account becomes an NPA. How the asset is classified and how much provision is required. They are central to prudent bank accounting and a frequent exam focus.

What is the difference between a provision and a write-off in banking?

A provision is an anticipated charge against profit to cover possible future losses. A write-off removes the asset value from the books to the extent considered irrecoverable. Creating a provision does not mean the asset has been written off.

How does the Core Banking System affect bank accounting?

The Core Banking System enables real-time transaction posting. Centralised ledger maintenance and uniform accounting across all branches. It cuts manual errors. Strengthens the audit trail and raises overall financial control and compliance standards.
