Unit 6: Question & Answer - Rectification of Errors | Principles and Practice of Accounting - CA Foundation PDF Download

Summary
♦ Unintentional omission or commission of amounts and accounts in the process of recording the transactions are commonly known as errors.
♦ Accounting errors are generally of four types-
(a) Errors of Principle;
(b) Errors of Omission;
(c) Errors of Commission;
(d) Compensating Errors.
♦ Some errors may affect the Trial Balance and some of these do not.
♦ The method of rectification of errors depends on the stage at which the errors are detected. If the error is detected before the preparation of trial balance, rectification is carried out by making the statement in the appropriate side of the concerned account.
♦ In case of the errors detected after the preparation of the trial balance, we open a suspense account with the amount of difference in the trial balance. Then complete journal entries can be passed for rectifying the errors.
♦ For rectifying the errors detected in the next accounting period, a special account 'Profit and Loss Adjustment Account' is opened for correction of amounts relating to expenses and incomes.

Theory Questions
Ques 1: How does errors of omission differ from errors of commission? 

Ans: (i) Errors of Omission: If a transaction is completely or partially omitted from the books of account, it will be a case of omission. Examples would be: not recording a credit purchase of furniture or not posting an entry into the ledger.
(ii) Errors of Commission: If an amount is posted in the wrong account or it is written on the wrong side or the totals are wrong or a wrong balance is struck, it will be a case of "errors of commission."

Ques 2: What is error of principle and how does it affect Trial Balance? 

Ans: Errors of principle: When a transaction is recorded in contravention of accounting principles, like treating the purchase of an asset as an expense, it is an error of principle. In this case there is no effect on the trial balance since the amounts are placed on the correct side, though in a wrong account. Suppose on the purchase of a typewriter, the office expenses account is debited; the trial balance will still agree.

Ques 3: When and how is Suspense account used to rectify errors?
Ans: The method of correction of error indicated so far is appropriate when the errors have been located before the end of the accounting period. After the corrections the trial balance will agree. Sometimes the trial balance is artificially made to agree inspite of errors by opening a suspense account and putting the difference in the trial balance to the account - the suspense account will be debited if the total of the credit column in the trial balance exceeds the total of the debit column; it will be credited in the other case. Each and every error detected can only be corrected by a complete journal entry. Those errors for which journal entries were not possible at the earlier stage will now be rectified by a journal entry(s), the difference or the unknown side is being taken care of by suspense account. Those errors for which entries were possible even at the first stage will now be rectified in the same way.
