Control accounts — common mistakes

Pay close attention to balances. A debit balance b/d is normal for an SLCA. However, a credit balance c/d can exist, representing customers who have overpaid or paid in advance. This credit balance must be shown as a current liability in the statement of financial position.

In exam questions, you will often be given a draft control account and a list of errors. You must prepare a corrected control account and/or a statement to reconcile the schedule of balances to the corrected control account balance. Read carefully to determine if an error affects the control account, the individual ledgers, or both.

No, they are memorandum accounts prepared outside of the double-entry system. Their purpose is to act as an independent check on the subsidiary ledgers. While the totals used to prepare them (e.g., total credit sales) come from the double-entry system, the control accounts themselves are a separate reconciliation tool.

Not necessarily. It only confirms arithmetical accuracy between the two sets of records. It would not reveal errors of omission (a transaction missed from both), errors of original entry (the same wrong amount posted to both), compensating errors, or errors of principle. It is a check, not a complete proof of accuracy.

Discounts allowed is an expense for the business, which is recorded with a debit in the Discounts Allowed account in the general ledger. However, within the Sales Ledger Control Account, its function is to reduce the total amount owed by customers. Since the SLCA is an asset account with a normal debit balance, any reduction (like a payment, return, or discount) must be a credit entry.
