Correcting Errors

To correct an error, prepare a journal entry that:

  1. Reverses the incorrect entry (if one was made)
  2. Records the correct entry

Or more efficiently, record the net adjustment needed.

Example: A repair of £500 was incorrectly debited to the motor vehicles account (capital expenditure) instead of the repairs expense account.

What was done: Dr Motor Vehicles £500 | Cr Cash £500
What should have been done: Dr Repairs Expense £500 | Cr Cash £500

Correcting entry: Dr Repairs Expense £500 | Cr Motor Vehicles £500

This moves the debit from the wrong account to the right account. The credit to cash was correct and doesn't need changing.

Examiner Tip

The 'Was Done / Should Be Done' Technique

For every error correction question: (1) Write out what WAS recorded. (2) Write out what SHOULD have been recorded. (3) The correcting entry is the difference between the two. This systematic approach prevents mistakes under exam pressure.

Practice Question

A sale of £750 to Customer A was incorrectly posted to Customer B's account. What type of error is this?

Practice Question
