Chapter 6 — Trial Balance and Rectification of Errors

Chapter 6 covers the meaning and preparation of a trial balance, its three objectives, the four types of accounting errors (commission, omission, principle, and compensating errors), methods for locating errors in a trial balance, and the process of rectifying errors both with and without a Suspense Account.

A trial balance is a statement showing the balances — or totals of debits and credits — of all accounts in the ledger, prepared with a view to verifying the arithmetical accuracy of posting into the ledger accounts. It is normally prepared at the end of an accounting year, but may also be prepared monthly, quarterly, or half-yearly.

The three objectives are: (i) to ascertain the arithmetical accuracy of ledger accounts; (ii) to help in locating errors; and (iii) to help in the preparation of financial statements, namely the Profit and Loss Account and the Balance Sheet.

The three methods are: the Totals Method (debit and credit totals of each account are listed), the Balances Method (the net balance of each account is listed — this is the most widely used method in practice), and the Totals-cum-Balances Method (a combination of both, with four amount columns).

No. A tallied trial balance only confirms that debits and credits have been arithmetically recorded correctly in the ledger. Errors such as errors of principle, compensating errors, and complete omissions do not affect the equality of debits and credits and therefore remain undetected even when the trial balance agrees.

The four types are: (i) errors of commission — caused by wrong recording, wrong posting, wrong casting, or wrong balancing; (ii) errors of omission — either complete (entire transaction not recorded) or partial (one side of posting omitted); (iii) errors of principle — arising from incorrect classification of capital and revenue items; and (iv) compensating errors — two or more errors whose combined effect on debits and credits is nil.

One-sided errors — those that affect only one account, such as a partial omission of posting, posting with a wrong amount to the correct account, or posting on the wrong side — cause the trial balance to disagree. Errors of principle and compensating errors do not affect the agreement, nor does a complete omission of recording.

A Suspense Account is a temporary account in which the difference in the trial balance is placed so that the accounting process and preparation of financial statements can continue without delay. It is closed once all errors affecting the trial balance are located and the amounts are transferred from the Suspense Account to the correct accounts through rectifying journal entries.

Such errors — also called two-sided errors — affect two or more accounts. They are rectified by recording a correcting journal entry that cancels the effect of the wrong debit or credit and restores the correct effect in the accounts concerned, without any need for a Suspense Account.

If all errors are not located before the financial statements are finalised, the remaining balance in the Suspense Account is carried forward to the next accounting period. When such prior-year errors are located and rectified in the next year, a Profit and Loss Adjustment Account is used instead of the original expense or income account.

If the difference between the debit and credit column totals is divisible by 2, it is likely that an amount equal to half the difference was posted to the wrong side of a ledger account. If the difference is a multiple of 9, it may indicate a transposition of figures — for example, recording 954 instead of 459.
