Important Differences Between Error of Omission and Error of Commission

Error of Omission

Sure, an error of omission in accounting occurs when a transaction or entry is completely left out or not recorded in the books of accounts, either in the subsidiary books or in the ledger. This can happen due to oversight, carelessness, or lack of knowledge.

For example, if a company receives payment from a customer but fails to record it in the books, the company’s accounts receivable balance will be understated, and this could impact the accuracy of the financial statements. Similarly, if an expense is not recorded, the company’s net income will be overstated.

Errors of omission can be more difficult to detect than errors of commission because they do not appear in any account. However, they can still be identified through regular account reconciliations and by comparing the accounting records to other sources of information, such as bank statements or invoices.

To prevent errors of omission, it is important to have proper internal controls in place, such as using accounting software with built-in checks and balances, ensuring that entries are double-checked by a supervisor, and training staff on proper accounting procedures.

Examples of Error of Omission

Here are some examples of errors of omission:

• A company receives payment from a customer but forgets to record it in the books of accounts.
• A company forgets to record a purchase of inventory in the books of accounts.
• An accountant fails to record an adjusting entry for accrued expenses at the end of the period.
• A business fails to report all of its income on its tax return.
• An employee fails to record a business expense in the accounting records, resulting in an incorrect expense total.
• A company forgets to record the depreciation expense for an asset in the books of accounts.
• A business fails to record the interest earned on its bank account in the books of accounts.

Types of Error of Omission

Here are some of the types of errors of omission that can occur in accounting:

1. Transaction Omission: This occurs when a transaction is completely left out or not recorded in the books of accounts. For example, a payment received from a customer may be forgotten to be recorded in the books.
2. Posting Omission: This occurs when a transaction is recorded in the subsidiary books but is not posted to the ledger. For example, a transaction may be recorded in the sales journal, but the corresponding entry is not made in the sales ledger.
3. Account Omission: This occurs when a particular account is not recorded in the books of accounts. For example, an expense account may be omitted from the chart of accounts.
4. Complete Omission: This occurs when an entire transaction is omitted from the books of accounts. For example, a company may forget to record all of its sales for a particular month.
5. Partial Omission: This occurs when a portion of a transaction is omitted from the books of accounts. For example, a company may forget to record a portion of a payment received from a customer.

Characteristics of Error of Omission

The characteristics of an error of omission in accounting include:

• Unintentional: Errors of omission are typically unintentional and occur due to oversight, carelessness, or lack of knowledge.
• Complete or partial: Errors of omission can be complete, where an entire transaction is missed out, or partial, where only a portion of the transaction is left out.
• Not immediately noticeable: Errors of omission are not immediately noticeable since there is no entry for the transaction, which can make them difficult to detect.
• Affects the trial balance: Errors of omission affect the trial balance since there is no entry for the transaction in the accounts, which can cause the trial balance to be out of balance.
• Impact on financial statements: Errors of omission can impact the accuracy of the financial statements, which can have consequences for decision-making and the overall financial health of the company.
• Can be prevented: Errors of omission can be prevented by implementing proper internal controls, such as double-checking entries and using accounting software with built-in checks and balances.
• Correction required: Errors of omission must be corrected as soon as they are detected to ensure that the financial statements are accurate and reliable. This can be done by making an adjusting entry or by correcting the original entry.

Error of Commission

An error of commission in accounting occurs when a transaction or entry is recorded incorrectly in the books of accounts. This can happen due to a mistake or error made by the accountant or bookkeeper, such as entering the wrong amount, using the wrong account, or making an incorrect calculation.

For example, if a payment is recorded twice, it will result in an overstated balance in the accounts. Similarly, if an expense is recorded in the wrong account, it can lead to an inaccurate balance in that account.

Errors of commission can be more easily detected than errors of omission because they result in an imbalance in the accounts. However, they can still be difficult to identify if they are not detected during regular account reconciliations and review.

To prevent errors of commission, it is important to have proper internal controls in place, such as segregating accounting duties, having a second person review entries, and using accounting software with built-in checks and balances. Additionally, training staff on proper accounting procedures and providing ongoing support and supervision can also help prevent errors of commission.

Examples of Error of Commission

Here are some examples of errors of commission in accounting:

• Recording a payment for the wrong vendor or supplier.
• Recording a sales transaction for the wrong customer or client.
• Recording an expense in the wrong account.
• Recording an incorrect amount for a transaction, such as entering $100 instead of $10.
• Failing to record a transaction in the correct accounting period.
• Recording a deposit in the wrong account.
• Recording a purchase as an asset instead of an expense.

Types of Error of Commission

Here are some common types of errors of commission in accounting:

1. Transposition error: This occurs when numbers or digits are reversed when entering them into the accounting system. For example, entering $54.32 as $45.32.
2. Incorrect account error: This occurs when a transaction is recorded in the wrong account. For example, recording a purchase of office supplies in the equipment account.
3. Duplication error: This occurs when a transaction is recorded more than once. For example, recording a sale twice.
4. Omission error: Although an error of omission is not considered an error of commission, it is worth mentioning here since it is the opposite of a commission error. An omission error occurs when a transaction is left out completely, and not recorded in the accounting system.
5. Calculation error: This occurs when a mathematical error is made, such as adding or subtracting incorrectly.
6. Timing error: This occurs when a transaction is recorded in the wrong accounting period. For example, recording a purchase made in January in February.
7. Name or identification error: This occurs when a vendor or customer is misidentified, resulting in incorrect records. For example, recording a payment to John Smith instead of John Doe.

Characteristics of Error of Commission

Here are some characteristics of an error of commission in accounting:

• It is a mistake made by the accountant or bookkeeper while recording a transaction in the books of accounts.
• It can occur due to various reasons, such as carelessness, lack of knowledge, inexperience, or deliberate intention.
• It results in an incorrect balance in the accounts affected by the error.
• It is easier to identify compared to errors of omission since it causes an imbalance in the accounts.
• It can have a significant impact on the accuracy of the financial statements and decision-making if not detected and corrected promptly.
• It can occur in various forms, such as transposition errors, incorrect account errors, duplication errors, calculation errors, timing errors, and name or identification errors.
• It can be prevented by implementing internal controls, such as segregating accounting duties, using accounting software with built-in checks and balances, and having a second person review entries.
• It can be corrected by making the necessary adjustments to the affected accounts, such as reversing or adjusting entries, and ensuring that the financial statements reflect the correct balances.
