Errors in Accounting

The trial balance is prepared to check the arithmetical accuracy of accounts. If the trial balance does not tally, it implies that there are arithmetical errors in the accounts which require location, detection and rectification thereof. Even if the trial balance tallies, there may still exist some errors. There are two types of errors:

  1. Errors which are not revealed by the trial balance, and
  2. Errors which are revealed by the trial balance.

1. Errors may happen at any of the following stages of the accounting cycle

At Recording Stage

  • Errors of principle
  • Errors of omission
  • Errors of commission

At Posting Stage

Error of omission

  • Complete
  • Partial

Error of commission

  • Posting to wrong account
  • Posting on the wrong side
  • Posting of wrong amount

At Balancing Stage

  • Wrong totaling
  • Wrong balancing

Preparation of Trial Balance

Error of Omission

Error of Commission

  • Taking wrong amount
  • Taking wrong account
  • Taking to the wrong side

2. Errors can be classified into the following four categories on the basis of the nature of errors and explained here under

  1. Errors of commission
  2. Errors of omission
  3. Errors of principle
  4. Compensating (offsetting) errors
  5. Errors of Duplication

Errors of Commission

These errors by definition are of clerical nature. These errors may be committed at the time of recording and/or posting. At the time of recording, the wrong amount may be recorded in journal which will be carried throughout. Such errors will not affect the agreement of the trial balance. These errors may also be committed at the time of posting, by way of posting wrong amount, to the wrong side of an account or in the wrong account. The errors resulting in posting to wrong account will not affect agreement of trial balance, whereas, other errors of posting will resulting disagreement of trial balance.

For example, an amount of Rs. 10,000 received from customer (Debtor) is correctly recorded on the debit side of the cash book but while posting, the customer's account is credited with Rs. 1,000. This is an error, which is committed at the time of posting, by posting wrong amount to the account. This will result in disagreement of trial balance, since, the credit total of the trail balance will be short by Rs. 9,000.

Errors of Omission

The errors of omission may be committed at the time of recording the transaction in the books of original entry or while posting to the ledger. An omission may be complete or partial. Such errors are known as errors of omission.

For example, Machinery purchased for Rs. 50,000 by issuing a cheque is recorded first in the credit side of cash book, in the bank column. Suppose it is not posted to the debit of machinery account, it is an error of partial omission. The trial balance will not tally. Suppose the transaction is not entered in the cash book and hence ignored completely, this is a case of complete omission. It means as if the transaction has not taken place at all. It will not affect the trial balance and hence the trial balance will tally. This is true only in case of complete omission.

Errors of Principle

Accounting entries are recorded as per the generally accepted accounting principles. If any of these principles are violated or ignored, errors resulting from such violations are known as errors of principle. As an illustration, Periodicity principle requires maintaining proper distinction between capital and revenue items. An error of principle may occur due to incorrect classification of expenditure or receipts between capital and revenue. This is very important because it will have an impact on financial statements. It may lead to under/over stating of income or assets or liabilities, etc.

For example, amount spent on additions to the buildings should be treated as capital expenditure and must be debited to the asset account. Instead, if this amount is debited to maintenance and repairs account, it is treated as a revenue expense. This is an error of principle. Since instead of asset account, i.e. buildings, the maintenance and repairs account (expense) is debited, the trial balance will still tally but would not be correct as per generally accepted accounting principles.

Such errors are not disclosed by the trial balance. This will result in understating of income due to extra charge under maintenance and repairs account and understating the value of buildings in the balance sheet.

Compensating Errors

When two or more errors are committed in such a way that the net effect of these errors on the debits and credits of accounts is nil, such errors are called compensating errors. They do not affect the tallying of the trial balance.

For example, In a credit sale transaction, the sales account is credited in excess by say, Rs.5,000 and similarly the suppliers account in case of a credit purchase is understated by Rs.5,000, this is a case of two errors compensating for each others effect. It is to be noted that extra credit to the sales account is offset by lower credit to the creditor's account, both being credit balance. Since, one plus is set off by the other minus, the net effect of these two errors being of compensating nature and do not affect the agreement of trial balance.

Errors of Duplication

Such errors arise when an entry in a book of original entry has been made twice and has also been posted twice.
