Objective A-D: The Trial Balance
A trial balance is a list of all general ledger account balances at a specific date, arranged in two columns: debit balances and credit balances. If the double-entry system has been applied correctly, the total of debit balances should equal the total of credit balances.
Purpose
- Verification: Checks the arithmetic accuracy of the double-entry system
- Starting point: Provides the data needed to prepare financial statements
- Error detection: Highlights certain types of errors (but not all)
Typical Debit and Credit Balances
| Debit Balances | Credit Balances |
|---|---|
| Non-current assets (cost) | Accumulated depreciation |
| Trade receivables | Trade payables |
| Inventory | Revenue |
| Cash/Bank | Share capital |
| Purchases | Share premium |
| Expenses (rent, wages, etc.) | Retained earnings |
| Drawings | Loans |
| Allowance for irrecoverable debts |
Limitations
A trial balance does NOT detect:
- Errors of omission: A transaction completely omitted from the books
- Errors of commission: Correct amount posted to the wrong account of the same type
- Errors of principle: Amount posted to the wrong type of account (e.g., expense instead of asset)
- Errors of original entry: Wrong amount used for both debit and credit
- Compensating errors: Two errors that cancel each other out
- Errors of reversal: Debit and credit entries swapped
A Balanced Trial Balance Does NOT Mean No Errors
Six types of errors will NOT cause the trial balance to be out of balance: omission, commission, principle, original entry, compensating, and reversal. The trial balance only detects errors where total debits ≠ total credits. This is a frequently tested limitation.
Which of the following errors would cause the trial balance to NOT balance?
