Adjusting & Closing Entries and Trial Balance Errors – Complete Accounting Guide

Adjusting entries accounting — this guide gives you the latest 2026 information, key dates, eligibility, fees and study tips for the JAIIB exam.

Adjusting entries and closing entries are the foundation of accurate financial reporting in accounting. These entries ensure that income. Expenses, assets, and liabilities are correctly stated at the end of every accounting period, forming the basis for reliable financial statements used by banks, businesses, and regulators alike.

Understanding Adjusting Entries

Adjusting entries are passed at the end of the accounting period to ensure financial statements reflect the true performance of the business. These entries arise because accounting follows principles rather than cash timing.

Two fundamental principles govern adjustments:

• Accrual Basis of Accounting
• Matching Concept

Under accrual accounting, incomes and expenses are recorded when they are earned or incurred, not when cash is received or paid. Without adjusting entries, profits may be overstated or understated.

Outstanding Expenses – Expenses Incurred but Not Paid

Outstanding expenses are expenses that have been incurred during the accounting period but have not yet been paid.

• Outstanding salaries
• Unpaid electricity bills
• Rent due but unpaid

If employees worked in March but salaries are paid in April, the expense still belongs to March. Hence, it must be recorded in the current year.

Effect:

• Expense increases
• Liability is created

Prepaid Expenses – Paid Now, Used Later

Prepaid expenses occur when payment is made in advance, but the benefit relates to future periods.

• Advance rent paid
• Insurance premium paid in advance

Only the portion related to the current year should be charged as an expense. The remaining portion becomes a current asset on the balance sheet.

Accounting Impact:

• Expense decreases
• Asset is created (Prepaid Expense Account)

Accrued Income – Earned but Not Received

Accrued income refers to income earned during the accounting period but not yet received in cash.

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

Income is recognized when earned under the accrual concept, ensuring correct profit measurement and proper recognition of receivables in the balance sheet.

Income Received in Advance – Cash Without Earning

Income received in advance arises when money is received before providing goods or services. Such receipts represent a liability since the obligation to deliver remains outstanding.

• Advance rent received
• Subscription received for future services
• Annual maintenance fees received upfront

Such receipts must not be treated as income of the current period. Only the earned portion belongs to the current year's income statement.

Why Adjusting Entries Are Non-Negotiable

Failure to pass adjusting entries results in serious distortions in financial reporting:

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

This is why adjusting entries are frequently tested in JAIIB examinations through MCQs and numerical problems in the Accounting and Finance for Bankers (AFB) paper.

Closing Entries – Clearing the Path for the Next Year

Closing entries are passed after adjustments to close income and expense accounts and transfer their balances to the Trading and Profit & Loss Account. They serve a critical purpose in the accounting cycle:

• Transfer gross profit or loss to the Profit & Loss Account
• Close all expense and income nominal accounts to zero
• Carry forward net profit or loss to the Capital Account or Retained Earnings

Closing entries ensure that income and expense accounts start with zero balance in the next accounting period, preventing accumulation of results across multiple financial years. Without closing entries, the Trial Balance for the next period would carry incorrect accumulated balances.

Errors in Accounting – Why Trial Balance May Still Tally

A tallied trial balance does not guarantee error-free accounts. Certain types of errors do not affect trial balance agreement because they either cancel each other out or affect both sides equally.

• Error of Commission: Entry is passed in the correct type of account but the wrong individual account (e.g., debit to Ramesh instead of Rajesh)
• Error of Omission: A transaction is completely omitted from the books; both debit and credit are absent
• Error of Principle: Entry is passed against the fundamental rules of accounting (e.g., treating capital expenditure as revenue expenditure)
• Compensating Error: Two or more errors cancel each other's effect, making trial balance appear correct despite incorrect accounts

Compensating errors are particularly deceptive because the trial balance tallies, yet the books are fundamentally wrong. These must be detected through detailed scrutiny rather than relying on the trial balance alone.

Trial Balance Systems – Gross vs Net

There are two systems of trial balance preparation, each with its own methodology:

• Gross Trial Balance System: Totals of debit and credit sides are separately computed for each ledger account and listed
• Net Trial Balance System: The net balance (difference between debit and credit totals) of each ledger account is taken and listed

The Net Trial Balance is more commonly used in practice as it is more compact and easier to work with when preparing final accounts.

Common Trial Balance Confusions Clarified

Several accounts create confusion about which side of the trial balance they appear on. These common clarifications are important for exam purposes:

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

Suspense Account – The Temporary Solution

When the trial balance does not tally due to certain errors. A Suspense Account is opened to temporarily balance the books while the errors are being investigated and rectified.

• Used for one-sided errors that affect only debit or credit
• Temporary in nature – must be closed after all errors are found and corrected
• Eliminated after rectification of all errors
• If the trial balance has excess on the debit side, the suspense account gets a credit balance

The suspense account is not a permanent account and should not appear in the final balance sheet. Its presence indicates unresolved errors in the books.

Key Points Summary

• Adjusting entries align expenses and incomes with the correct accounting period under the accrual and matching concepts
• Outstanding expenses increase liabilities; prepaid expenses create assets
• Closing entries reset nominal accounts to zero at year-end and transfer net result to capital
• A tallied trial balance does not mean error-free accounts – errors of omission, commission, principle, and compensating errors escape detection
• The Suspense Account is a temporary measure to handle one-sided errors until they are fully rectified

Frequently Asked Questions

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

Adjusting entries ensure that revenues are recognized when earned and expenses are recorded when incurred, regardless of when cash changes hands. This complies with the accrual basis of accounting and 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 is one that has been incurred but not yet paid (a liability). While a prepaid expense is one that has been paid but relates to a future period (an asset). Both require adjusting entries to correctly state the period's profit.

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

Yes. Errors of omission, commission, principle, and compensating errors do not affect the agreement of the trial balance. Only one-sided errors (affecting only debit or only credit) cause the trial balance to disagree.

Q4. What is the purpose of closing entries?

Closing entries transfer the balances of all income and 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 the suspense account has an unresolved balance at year-end, it must be carried forward to the next year and disclosed in the balance sheet. It should not be permanently retained, as it indicates undetected errors that must be investigated and corrected.

Conclusion

Adjusting entries and closing entries form the backbone of accurate accounting. They ensure that profits. Assets, and liabilities are correctly stated for every accounting period, providing reliable information to all stakeholders including bank management, auditors, and regulators. Understanding trial balance limitations, error rectification techniques, and the role of the suspense account is essential for JAIIB examination success and for sound banking practice. Consistent practice of adjusting entry problems and error rectification exercises will strengthen your grasp of these fundamental accounting concepts.
