1. Chapter 32 Errors not affecting the balancing of the trial balance

2. Learning objectives
After you have studied this chapter, you should be able to:
Correct errors which are not revealed by a trial balance
Distinguish between the different kinds of errors that may arise

3. Types of errors
There are seven errors that may exist in the double entry bookkeeping but will not be revealed in a trial balance:
Errors of omission, where a transaction is completely omitted from the books.
Errors of commission, where a transaction is posted to the wrong account name, for instance K. Green instead of C. Green.
Errors of principle, where a transaction is posted to the wrong class of account, for instance confusing assets with expenses.

4. Types of errors (Continued)
Compensating errors, where two completely separate errors cancel each other out.
Errors of original entry where the figure posted is incorrect.
Complete reversal of entries, where the correct accounts are used but the postings were made on the wrong side of the accounts.
Transposition errors, where the figures posted have been transposed, so £142 was entered instead of £124.

5. How to correct errors Errors are always corrected by:
Constructing a journal entry and including a suitable narrative.
Posting the journal entries to the ledger accounts to correct the error.

6. Error of omission
A sale of £59 worth of goods to E. George has been completely omitted from the books

7. Error of commission
A purchase of £44 worth of goods from C. Simons on 4 September was entered in error in C. Simpson’s account. The error was found on 30 September.

8. Error of commission (Continued)

9. Error of principle
The purchase of a machine for £200 is debited to the purchases account instead of being debited to a machinery account.

10. Compensating error
In the cash book, the amount of cash sales transferred to the sales account was overstated by £20 and the amount transferred to the wages account was also overstated by £20.

11. Error of original entry
A sale of £38 to A. Smailes was entered in the books as £28.

12. Complete reversal of entries
A payment of cash of £16 to M. Dickson was entered on the receipts side of the cash book in error and credited to M. Dickson’s account.

13. Transposition error
A credit purchase from P. Maclaran costing £56 was entered in the books as £65.

14. Learning outcomes You should have now learnt:
How to describe each of a range of possible errors that can be made when recording financial transactions in the accounts that will not be detected by producing a trial balance
How to identify and correct each of these types of errors

15. Learning outcomes (Continued)
That when errors are found, they should be amended by using proper double entry procedures
That all corrections of errors should take place via the Journal, where entries are first recorded before being posted to the appropriate ledger accounts
