Correct accounting is crucial for human resource professionals who often collaborate with finance teams to manage payroll, benefits, and employee-related expenses. Understanding how to identify and correct errors that affect the trial balance ensures accurate financial reporting and compliance with Kenyan accounting standards. This chapter focuses on errors that impact the trial balance and equips HR practitioners with the knowledge to detect and address these issues effectively.

5.1 Cash book and bank statement balance discrepancies:

The cash book is the business's own record of its bank account, while the bank statement is the bank's record of the same account. On any date the two balances are rarely equal, even though both describe the same money. The differences arise from timing, from items one party has recorded and the other has not yet, and from mistakes. Finding and explaining each difference is the work of reconciliation, and it protects the business against fraud, overdrafts and misstated cash. Example: the accountant of a school in Nyeri finds a cash book bank balance of Ksh 215,000 on 31 March, while the bank statement shows Ksh 238,500, and must trace the Ksh 23,500 difference to specific items.

The discrepancies fall into three groups: items in the cash book but not yet on the bank statement, items on the bank statement but not yet in the cash book, and errors. How the cash book is updated is covered in 5.2, and the reconciliation statement itself is in 5.3.

5.1.1 Items appearing in the cashbook but not in the bank statement

These are transactions the business has recorded in its cash book but which the bank has not yet processed by the statement date. They are mostly timing differences, and they correct themselves in the following period. Example: a hotel in Malindi writes a cheque for Ksh 30,000 on 29 March, but the supplier banks it on 3 April, so it does not appear on the March statement.

• Unpresented cheques: Cheques issued to suppliers and recorded as payments in the cash book, but not yet presented to the bank for payment. They make the bank statement balance higher than the cash book balance.
• Uncredited deposits (outstanding lodgements): Cash or cheques banked and recorded on the debit side of the cash book, but not yet credited by the bank, often because they were deposited on the last day or are still clearing. They make the bank statement balance lower than the cash book balance.
• Stale cheques: Cheques that remain unpresented for more than the validity period, usually six months. The bank will refuse them and the business may have to reverse the entry or reissue the payment.
• Cheques received but not yet banked: Cheques held in the office at the period end, which are in the cash book but not yet at the bank.

5.1.2 Items appearing in the bank statement but not in the cash book

These are transactions the bank has processed which the business has not yet recorded. The cash book must be corrected for them, because they are real changes in the bank balance. Example: a SACCO in Nyeri finds on its statement a bank charge of Ksh 1,200 that it did not know about.

• Bank charges: Ledger fees, transaction fees and commissions deducted by the bank. They are debited by the bank and must be entered on the credit side of the cash book.
• Interest charged: Interest on an overdraft, deducted by the bank. It is a credit entry in the cash book.
• Interest received: Interest earned on a credit balance, added by the bank. It is a debit entry in the cash book.
• Direct credits: Amounts paid directly into the account by customers, such as bank transfers or mobile payments, not yet advised to the business. They are debits in the cash book.
• Standing orders and direct debits: Regular payments, such as insurance premiums, rent or loan instalments, paid automatically by the bank. They are credits in the cash book.
• Dishonoured cheques: Customers' cheques that were banked and recorded but returned unpaid. The cash book must be credited, and the customer's account debited again.
• Direct payments by the bank: Payments such as taxes or loan repayments made on the business's instruction without a cheque, entered as credits in the cash book.

5.1.3 Errors

Errors are mistakes made by the business or by the bank. They produce differences that are not timing differences and must be corrected as soon as they are found. Example: a contractor in Thika records a cheque of Ksh 8,500 in the cash book as Ksh 5,800, while the bank has debited Ksh 8,500.

• Errors in the cash book: Wrong amounts, transposed figures such as Ksh 540 recorded as Ksh 450, items posted on the wrong side, omitted entries and wrong additions or balancing. They are corrected in the cash book.
• Errors by the bank: The bank credits or debits the wrong account or the wrong amount. The business reports the error and it is corrected on the bank's side, but it is shown in the reconciliation until the bank corrects it.
• Duplicated entries: The same cheque or deposit is recorded twice in the cash book.
• Omitted entries: A transaction is missed entirely in the cash book.
• Wrong side: A receipt entered as a payment, or a payment as a receipt, which changes the balance by twice the amount.

Formula: difference between two balances = cash book balance − bank statement balance

Example: the Nyeri school has a cash book balance of Ksh 215,000 and a statement balance of Ksh 238,500, a difference of 238,500 − 215,000 = Ksh 23,500. The accountant finds the following.

Unpresented cheques: Ksh 40,000

Uncredited deposits: Ksh 12,000

Bank charges not in the cash book: Ksh 1,500

Direct credit not in the cash book: Ksh 5,000

Working: 238,500 − 40,000 + 12,000 = Ksh 210,500 (adjusted bank balance)

215,000 − 1,500 + 5,000 = Ksh 218,500 (adjusted cash book balance)

The two figures do not agree. The difference is 218,500 − 210,500 = Ksh 8,000, which signals an error. On checking, the accountant finds that a cheque of Ksh 8,000 was recorded as Ksh 16,000 in the cash book on the payment side.

The cash book error is corrected: the payment was overstated by Ksh 8,000, so the cash book balance rises.

Corrected cash book balance: 218,500 + 8,000 = Ksh 226,500

This is not equal to 210,500 either, so the error was the other way round. Recalculating, the cheque was recorded as Ksh 8,000 instead of Ksh 16,000, understating the payment, so the cash book balance falls.

Corrected cash book balance: 218,500 − 8,000 = Ksh 210,500

Both balances now agree at Ksh 210,500.

Chapter Summary

This chapter explores the different types of accounting errors and their impact on the trial balance. Errors affecting the trial balance occur when debit and credit entries are not equal, causing the trial balance to fail to balance, while errors that do not affect the trial balance include mistakes such as omission or commission that leave the trial balance balanced but still distort financial records. The chapter then details the procedures for correcting these errors, emphasizing the importance of accurate adjustments to maintain reliable financial information. The suspense account is introduced as a temporary holding account used to balance the trial balance when errors are detected but not yet fully resolved. Attention is given to how reported gross and net profits can be misstated due to accounting errors and the necessity of correcting these figures for accurate financial reporting. Finally, the chapter explains the preparation of the final statement of financial position after all errors have been identified and corrected, ensuring that financial statements reflect the true financial status of the business.
