Adjusting & Closing Entries and Trial Balance Errors: The Complete 2026 JAIIB

Adjusting and closing entries — this guide gives you the latest 2026 information. Key dates, eligibility, fees and study tips for the IIBF Certifications exam.

Mastering adjusting. Closing entries is the single fastest way to add marks in the JAIIB Accounting &. Finance for Bankers (AFB) paper.

These entries decide whether your profit. Your assets and your liabilities are stated correctly at year-end. Get them wrong and every financial statement that follows is wrong too.

This 2026 guide rebuilds the topic from the ground up. You will learn what adjusting entries are. How closing entries reset the books.

Why a trial balance can tally even when the accounts are wrong. And how the suspense account quietly holds everything together. Every concept comes with a plain-English example.

The exact journal entry examiners expect.

What Are Adjusting and Closing Entries in Accounting?

Adjusting. Closing entries are two distinct steps near the end of the accounting cycle. Both are passed after the unadjusted trial balance is drawn up. But they do very different jobs.

Adjusting entries update accounts so the financial statements show the true performance of the period. Closing entries then clear out the temporary income. Expense accounts so the next year starts clean.

The reason both exist is simple. Accounting runs on principles, not on the timing of cash. Two principles drive every adjustment:

• Accrual Basis of Accounting — record income when earned and expenses when incurred. Not when cash moves.
• Matching Concept. Match the expenses of a period against the revenue they helped generate.

Without adjusting entries, profit is routinely overstated or understated. That single distortion can mislead bank management, auditors and investors alike.

Why Adjusting Entries Matter for Bankers

Banks lend against financial statements. If a borrower's accounts ignore outstanding expenses or treat advance income as current profit. The picture looks healthier than reality. A banker who cannot spot this is exposed.

This is exactly why the JAIIB AFB paper tests adjusting entries so heavily. Through both theory MCQs and small numerical problems. Strong fundamentals here protect your marks and, later, your credit decisions.

The Four Core Adjusting Entries You Must Know

Most adjustment questions reduce to four scenarios. Learn the logic once and you can solve any variation. The table below is your quick-reference cheat sheet.

1. Outstanding Expenses — Incurred but Not Paid

Outstanding expenses are costs incurred during the period. Still unpaid at year-end. Common examples include:

• Outstanding salaries
• Unpaid electricity bills
• Rent due but not yet paid

Suppose employees worked in March but salaries are paid in April. The expense belongs to March. So it must be recorded in the current year. The effect is that expense increases and a liability is created.

2. Prepaid Expenses — Paid Now, Used Later

Prepaid expenses arise when you pay in advance. The benefit relates to a future period. Think of advance rent or an insurance premium paid up front.

Only the portion that relates to the current year is charged as an expense. The unused portion becomes a current asset on the balance sheet. So expense decreases and an asset is created.

3. Accrued Income — Earned but Not Received

Accrued income is income earned during the period. Not yet received in cash. Examples include:

• Interest accrued on bank deposits
• Rent due from tenants
• Commission earned but not yet billed

Under the accrual concept, income is recognised when earned. This gives correct profit. Records a receivable as an asset in the balance sheet.

4. Income Received in Advance — Cash Without Earning

Income received in advance is money received before goods or services are delivered. Because the obligation to deliver remains, it is a liability, not income. Examples include advance rent received. Subscriptions for future services, and annual maintenance fees taken upfront.

Only the earned portion belongs in this year's income statement. The rest is carried forward.

Why Adjusting Entries Are Non-Negotiable

Skip the adjustments and the damage spreads across the whole report:

• Incorrect profit or loss figure
• Misstated assets and liabilities on the balance sheet
• Wrong decisions by management, investors and bankers
• Non-compliance with accrual accounting standards

This cascade is why examiners love the topic. A single missed adjustment in a numerical question changes every subsequent figure. Reinforce the logic with our free free guides and timed mock tests.

Closing Entries — Clearing the Path for Next Year

Closing entries are passed after adjustments. Their job is to close income. Expense (nominal) accounts.

Transfer their balances to the Trading and Profit &. Loss Account. They achieve three things:

1. Transfer gross profit or gross loss to the Profit & Loss Account.
2. Close every expense and income account to a zero balance.
3. Carry the net profit or loss to the Capital Account or Retained Earnings.

The point is a clean slate. Nominal accounts must start the next year at zero so results do not pile up across financial years. Without closing entries. The next period's trial balance would carry false accumulated balances.

Adjusting Entries vs Closing Entries: Quick Comparison

Errors in Accounting — Why the Trial Balance Still Tallies

Here is the trap that catches most students. A tallied trial balance does not guarantee error-free accounts. Some errors either cancel each other out or hit both sides equally. So the totals still agree.

Four classic errors escape detection:

• Error of Commission: the entry hits the correct type of account. The wrong individual account. For example. Debiting Ramesh instead of Rajesh.
• Error of Omission: a transaction is left out completely. So both the debit and the credit are missing.
• Error of Principle: the entry breaks a fundamental rule — for example. Treating capital expenditure as revenue expenditure.
• Compensating Error: two or more errors offset each other. Making the trial balance look correct despite wrong accounts.

Compensating errors are the most deceptive. The trial balance tallies, yet the books are fundamentally wrong. These are found only through detailed scrutiny. Never by trusting the trial balance alone.

Trial Balance Systems — Gross vs Net

There are two recognised methods of preparing a trial balance:

• Gross Trial Balance System: the total of the debit side. The total of the credit side are computed separately for each ledger account. Listed.
• Net Trial Balance System: only the net balance. The difference between the debit and credit totals of each account. Is listed.

The Net Trial Balance is more common in practice. It is compact and easier to use when preparing final accounts.

Common Trial Balance Confusions Cleared Up

A handful of accounts trip students up on. Side they belong to. Memorise this list — it is frequently tested.

• Purchases — Debit side (an expense).
• Sales — Credit side (an income).
• Fixed Deposits — Debit side (an asset of the business).
• Bank Overdraft — Credit side (a liability).
• Closing Stock. Does not appear in the trial balance unless adjusted through a closing stock entry.
• Outstanding Expenses — Credit side (a liability).
• Prepaid Expenses — Debit side (an asset).

The Suspense Account — A Temporary Solution

When a trial balance does not tally because of one-sided errors. A Suspense Account is opened to balance the books temporarily. The errors are traced and corrected.

• Used for one-sided errors that affect only the debit or only the credit.
• Strictly temporary. It must be closed once every error is found and rectified.
• It is eliminated after full rectification.
• If the trial balance shows excess on the debit side. The suspense account carries a credit balance (and vice versa).

A suspense account should never appear in the final balance sheet as a permanent item. Its presence is a red flag that errors are still unresolved.

How to Study This Topic and Score Higher

Theory alone will not carry you through the AFB numerical questions. Use this practical routine:

1. Learn the four adjustments cold. Recite the journal entry. Its effect on profit and the balance sheet for each.
2. Drill numerical problems daily. Pass adjustments through both the Profit &. Loss Account and the balance sheet so you see the double effect.
3. Build an error-spotting checklist. For every error in a question. Ask: does it touch one side or both? That single test tells you whether the trial balance will disagree.
4. Practise rectification with a suspense account. Open it, post corrections, and confirm it closes to zero.
5. Time yourself. Attempt full sets on our mock tests with bilingual explanations to build exam speed.

For exact marks weightage and the latest pattern. Always confirm on the most recent official IIBF notification before your attempt.

Common Mistakes to Avoid

• Treating a tallied trial balance as proof of accuracy. It is not — four error types hide behind it.
• Recording the full prepaid or advance amount in the current period. Split it; only the earned or used portion belongs this year.
• Forgetting the dual effect. Every adjustment changes the Profit &. Loss Account and the balance sheet together.
• Placing closing stock in the trial balance by default. It enters only when adjusted through a closing stock entry.
• Leaving the suspense account open. If it survives to the balance sheet, errors are still unresolved.
• Confusing outstanding (liability) with prepaid (asset). Reverse them and your whole answer flips.

Frequently Asked Questions

Q1. What is the main purpose of adjusting entries in accounting?

Adjusting entries ensure revenues are recognised when earned. Expenses are recorded when incurred. Regardless of when cash changes hands. This satisfies the accrual basis of accounting. Gives a true picture of profitability for the period.

Q2. What is the difference between an outstanding expense and a prepaid expense?

An outstanding expense has been incurred but not yet paid. So it is a liability. A prepaid expense has been paid but relates to a future period. So it is an asset. Both need adjusting entries to state the period's profit correctly.

Q3. Can a trial balance tally even when there are errors in the books?

Yes. Errors of omission. Commission.

Principle. Compensating errors do not affect the agreement of the trial balance. Only one-sided errors.

Which affect only the debit or only the credit. Cause it to disagree.

Q4. What is the purpose of closing entries?

Closing entries transfer the balances of all income. Expense accounts to the Trading and Profit &. Loss Account. And then the net profit or loss to the Capital Account. This resets nominal accounts to zero for the next accounting period.

Q5. What happens if the suspense account is not closed by the end of the year?

If a balance remains. It is carried forward. Disclosed in the balance sheet for the time being. It should never be retained permanently. Because it signals undetected errors that must be investigated and corrected.

Conclusion

Adjusting and closing entries are the backbone of accurate accounting. They make sure profit. Assets and liabilities are stated correctly every period. Giving reliable information to bank management, auditors and regulators.

Add a clear grip on trial balance limitations. Error rectification and the suspense account. And you have the full toolkit for JAIIB success.

Sound banking practice. Keep drilling adjustment and rectification problems — repetition turns these rules into instinct. You have got this.
