Errors Which Do Not Affect a Trial Balance

Which errors do not affect the trial balance?

  • There may be errors even though the totals in the trial balance are equal

  • These errors might be spotted by other means

    • Control accounts

    • Bank reconciliation statements

  • These errors cannot be ignored

    • They could affect the stated profit

    • They could affect the stated value of assets and liabilities

    • They could affect the balances related to other businesses

  • The six types of errors which do not affect a trial balance are:

    • Error of omission

    • Error of original entry

    • Error of complete reversal

    • Error of commission

    • Error of principle

    • Compensating errors

Examiner Tips and Tricks

You need to learn the names and definitions of these six errors!

How do I correct errors using journal entries?

  • You can correct errors by making the appropriate entries into the ledger accounts

  • The journal will be used as a book of prime entry

  • Enter the account that needs to be debited

    • It is conventional for debit entries to appear first

  • Enter the account that needs to be credited

    • It is conventional to indent the details for credit entries

  • Give a narrative for the journal entry

    • State “Correction of error”

    • Give a brief description of the error

Error of Omission

What is an error of omission?

  • An error of omission occurs when a transaction is not entered into any ledger accounts

    • The transaction is omitted

    • It is possible that the transaction was not entered into the books of prime entry

  • The transaction is not included in the total for the debits and the total for the credits

    • The totals will therefore balance

How do I correct an error of omission?

  • Enter the transaction correctly into the ledger accounts

    • You essentially just need to make the entries as normal

  • Make the journal entries

Worked Example

Error of Original Entry

What is an error of original entry?

  • An error of original entry occurs when a transaction is entered into both of the ledger accounts using an incorrect amount

    • The same incorrect amount is entered into both the debit account and the credit account

    • It is possible that the amount of the transaction was entered incorrectly into the books of prime entry

  • The incorrect amount is included in the total for the debits and the total for the credits

    • The totals will therefore balance

How do I correct an error of original entry?

  • Find the difference between the incorrect amount and the correct amount

  • Enter the difference into both accounts

    • To increase an amount

      • Put the difference on the same side as the original entry

    • To decrease an amount

      • Put the difference on the opposite side to the original entry

Worked Example

On 1 March 2024, Ashika identified an error where the sale of goods worth $200 to Kiha was entered into the sales journal as $250. Kiha’s account was debited $250, and the sales account was credited $250.

Prepare journal entries to correct the error. A narrative is required.

Answer

  • The amount entered was $50 more than the correct amount

  • Decrease both accounts by $50

    • To decrease the accounts, enter $50 on the opposite sides compared to the original entries

Error of Complete Reversal

What is an error of complete reversal?

  • An error of complete reversal occurs when a transaction is entered into the wrong sides of both of the correct ledger accounts

    • The account that was debited should have been credited

    • The account that was credited should have been debited

  • The correct amount is included in the total for the debits and the total for the credits

    • The totals will therefore balance

How do I correct an error of complete reversal?

  • Double the value of the transaction

    • This is because you need to apply the transaction twice

      • Once to undo the error

      • Once to make the correct entries

  • Make the entries on the correct side

    • This will be the opposite side to where it was entered

Worked Example

On 1 March 2024, Ashika identified an error where goods sold to Kiha, for $200, were debited to the sales account and credited to Kiha’s account. 

Prepare journal entries to correct the error. A narrative is required.

Answer

An amount of $400 is needed to fix the error

Error of Commission

What is an error of commission?

  • An error of commission occurs when one entry for a transaction is entered into an incorrect account but the type of account is correct

    • A debit entry could have been entered into the wrong expense account

    • A transaction could have been entered into an account for the incorrect customer

    • A transaction could have been entered into an account for the incorrect supplier

  • The correct amount is included in the total for the debits and the total for the credits

    • The totals will therefore balance

How do I correct an error of commission?

  • Undo the entry in the incorrect account

    • This means making an equal entry on the opposite side of the account

  • Make an entry in the correct account

Worked Example

On 1 March 2024, Ashika identified an error where goods were sold to Kiha for $200, but the entry was made in Dinah’s account in the sales ledger. The transaction was entered correctly in the sales account.

Prepare journal entries to correct the error. A narrative is required.

Answer

  • Dinah’s account has been debited by mistake

    • Undo the mistake by crediting Dinah’s account

    • Debit Kiha’s account

Error of Principle

What is an error of principle?

  • An error of principle occurs when one entry for a transaction is entered into an incorrect account and the type of account is also incorrect

    • A transaction for an expense could have been entered into an asset account

  • The correct amount is included in the total for the debits and the total for the credits

    • The totals will therefore balance

Examiner Tips and Tricks

It is very easy to confuse an error of principle with an error of commission. An error of commission occurs when an account is confused with another account that has something in common. For example, they are both expenses, or they are both trade receivables.

How do I correct an error of principle?

  • You correct an error of principle the same way as you would correct an error of commission

  • Undo the entry in the incorrect account

    • This means making an equal entry on the opposite side of the account

  • Make an entry in the correct account

Worked Example

On 1 March 2024, Ashika identified an error where $50 was paid for petrol, but the entry was made in the vehicles account rather than the vehicle expenses account. The transaction was entered correctly in the cash book.

Prepare journal entries to correct the error. A narrative is required.

Answer

  • The vehicles account has been debited by mistake, as this is an asset account not an expense account

    • Undo the mistake by crediting the vehicles account

    • Debit the vehicle expenses account

Compensating Errors

What are compensating errors?

  • Compensating errors occur when the effects of unrelated errors balance out when totalling the debits and credits

  • Example

    • A business sells $100 worth of goods to Steve and $200 worth of goods to Tony

    • The transactions were entered correctly into the sales account

    • Both Steve and Tony’s accounts were debited $150

      • Overall the assets have still increased by $300

How do I correct compensating errors?

  • Correct each error separately

  • The total of the debits should equal the total of the credits

Worked Example

Ashika sold $100 worth of goods to Steve and $200 worth of goods to Tony. On 1 March 2024, Ashika identified that both of these transactions were entered into the sales ledger accounts as $150. The transactions were entered correctly into the sales account.

Prepare journal entries to correct the error. A narrative is required.

Answer

Steve’s account was debited $150 instead of $100
Therefore, credit $50 to Steve’s account to reduce the balance

Tony’s account was debited $150 instead of $200
Therefore, debit $50 to Tony’s account to increase the balance

  1. Payment of cash, $600, to Fran, a credit supplier, had been debited to the account of Fred in the purchases ledger.

  2. Rent paid by direct direct, $800, had not been recorded in the ledger accounts.

  3. Office expenses, $150, had been debited to the office equipment account.

  4. Wages paid, $500, had been debited to the bank account and credited to the wages account.

For each of the items, state the type of error that was made.
