Trial Balance Concepts

What is a Trial Balance?

• A trial balance is a bookkeeping worksheet in which the balance of all ledger accounts are complied into debt or credit account column totals that are equal.

Purpose of a Trial Balance

• To ensure that the entries in a company's bookkeeping system are mathematically correct.

• Provides a list of General Ledger (GL) accounts from which Income statements And Balance sheets are prepared.

Errors Found by Preparing the Trial Balance

The Trial Balance will disclose the following types of errors:

• Recording an account balance on the wrong side: e.g., entering a debit as a credit.

• Failing to record part of a transaction: Not entering both sides of the entry in the ledger.

• Transposition errors: Writing numbers incorrectly, e.g., $374 instead of $347.

• Mistakes when balancing accounts: Errors made during the final balance process.

• Leaving a ledger account balance out: Omitting an account entirely from the Trial Balance.

• Inadvertently making 2 debit or 2 credit entries: Which will make the column totals unequal.

Errors Not Disclosed by the Trial Balance

The Trial Balance will NOT reveal the following types of errors:

• Error of Omission: Not recording a transaction at all, e.g., failing to record a wage payment.

• Error of Commission: Errors made by entering a transaction in the wrong ledger account but on the correct side, e.g., recording Office furniture instead of Office Equipment.

• Error of Original Entry: Making an initial error in the amount, e.g., recording $4700 instead of the actual $4900 for inventory sold.

• Making an entry on the wrong side: Entries can cancel each other out if balanced incorrectly.

• Compensating Errors: Two independent errors that offset each other, leaving no visible indication of discrepancies.
