8.2. Types of Errors

Errors of Omission

• Definition: These errors occur when a transaction is completely omitted from the books of accounts.
• Examples:
  • Failure to record a sale or purchase in the journal.
  • Not recording accrued expenses or income.
• Rectification: The missing entry must be recorded in the journal and posted to the ledger.

Errors of omission happen when a transaction that should have been recorded is missing entirely. For instance, if a business makes a sale but doesn't write it down in the journal, this sale does not appear in the financial records. To correct this, the accountant must locate the missed transaction and make the necessary entry into the journal and subsequently post it to the ledger to ensure accurate records.

Imagine you're keeping a diary of your daily expenses and completely forget to write down a dinner you had with friends. Later, when you check your diary, you realize your total spending for the week is off because that dinner expense is missing. To fix this, you need to add that dinner expense to your diary.

Errors of Commission

• Definition: These errors occur when a transaction is recorded incorrectly in terms of amount, account, or classification, but it is recorded in the books.
• Examples:
  • A payment recorded in the wrong account (e.g., recording office supplies as office expenses).
  • Incorrect amount entered in the journal or ledger.
• Rectification: The incorrect entry must be corrected by passing a journal entry to reverse the error and record it correctly.

Errors of commission involve inaccuracies in recording transactions that have already been logged into the accounts. For example, if a business records a payment of $100 as$10, although the company has documented the payment, the incorrect amount may lead to severe mismanagement of finances. Therefore, the error needs to be reversed and the correct amount recorded through appropriate journal entries.

Think of a scenario where you write a check for $150 but accidentally record it as$15 in your checkbook. When you check your checkbook balance, it shows you've spent much less than you actually have. Thus, to correct this error, you would need to adjust your record by adding the $135 difference to clarify how much you've spent.

Errors of Principle

• Definition: These errors occur when a transaction is recorded in violation of accounting principles or rules.
• Examples:
  • Treating capital expenditure as revenue expenditure.
  • Recording a revenue expense as an asset.
• Rectification: The wrong entry is reversed and reclassified according to the correct accounting principle.

Errors of principle arise when transactions are recorded in a manner that contradicts established accounting principles. For instance, if a company sets a capital expense (like purchasing machinery) into daily operating expenses, it misrepresents the financial situation. Hence, to resolve this, the accountant must reverse the incorrect entry and classify the transaction correctly in accordance with the accounting rules.

Imagine you run a bakery. If you decide to label the cost of a new oven (a long-term asset) as part of your daily baking expenses, your profit calculations will be skewed. If your business expenses are shown higher than they should be, it could mislead investors or partners about your bakery's actual performance. Correcting this means placing the oven's expense in the correct category of 'assets' instead of 'monthly expenses'.

Compensating Errors

• Definition: These errors occur when two or more errors offset each other, and thus the trial balance may appear to be correct.
• Examples:
  • Overstating one entry and underreporting another by the same amount.
• Rectification: These errors need to be individually identified and corrected even though they do not affect the trial balance.

Compensating errors occur when two mistakes cancel each other out. For example, if one account is mistakenly increased by $100 while another account is decreased by the same amount, the trial balance will still appear correct despite the underlying errors. It is crucial to identify and rectify each error to ensure the financial records are accurate and trustworthy.

Consider a situation where you accidentally overpay your utility bill by $50, but at the same time, you forget to pay your cable bill, which is also$50. Your overall account statement looks accurate as the $50 overpayment is counterbalanced by the$50 underpayment. To fix this, you’ll need to correct both entries to accurately reflect your actual expenses.

Errors of Duplication

• Definition: These errors occur when an entry is recorded more than once, leading to an overstated balance.
• Examples:
  • Recording the same sale twice.
• Rectification: The duplicate entry must be identified and reversed.

Errors of duplication take place when a transaction is entered multiple times in the accounting records. This issue can inflate financial figures, making it seem like the business has more income or expenses than it actually does. To resolve this, it’s necessary to identify the duplicate entries and make a journal entry to reverse one of them, ensuring accurate financial reporting.

Think of keeping a grocery list where you accidentally write down 'apples' twice. When you go shopping, you might end up buying more apples than you need because of the duplication on your list. To remedy this, you would need to check your list, find the repeated item, and remove one of the entries to ensure you only purchase the apples you actually want.
