What you'll learn
Bank Reconciliation Statements form a critical component of CIE IGCSE Accounting Paper 1, regularly appearing as structured questions worth 10-15 marks. This topic tests your ability to identify and explain differences between a business's cash book and the bank statement, then prepare either an updated cash book or a formal reconciliation statement. Mastering this skill demonstrates your understanding of control accounts, timing differences, and double-entry principles.
Key terms and definitions
Cash Book — The ledger account maintained by a business to record all cash and bank transactions, forming part of the double-entry bookkeeping system.
Bank Statement — A document issued by the bank showing all transactions processed through the business's bank account during a specific period.
Bank Reconciliation Statement — A statement prepared to explain differences between the cash book balance and the bank statement balance at a given date.
Unpresented Cheques — Cheques issued by the business and recorded in the cash book but not yet presented to the bank for payment, so they do not appear on the bank statement.
Outstanding Lodgements (Uncredited Deposits) — Amounts paid into the bank by the business and recorded in the cash book but not yet processed by the bank, so they do not appear on the bank statement.
Direct Debit — A payment instruction that allows a third party to collect money directly from the business's bank account, appearing on the bank statement before the business records it.
Standing Order — A regular fixed payment set up by the business, which may be recorded in the cash book before or after it appears on the bank statement.
Dishonoured Cheque — A cheque received by the business and initially recorded as payment but subsequently returned by the bank due to insufficient funds in the drawer's account.
Core concepts
Why differences occur between the cash book and bank statement
The cash book and bank statement rarely show the same balance on any given date. These differences arise from two main categories:
Timing differences occur when transactions are recorded in one record before the other. These are temporary differences that will resolve themselves over time:
- Unpresented cheques that the business has issued
- Outstanding lodgements that the bank has not yet credited
- Cheques recorded by the business but not yet cleared by the bank
Items on the bank statement unknown to the business represent transactions the bank has processed but the business has not yet recorded:
- Bank charges and interest debited by the bank
- Direct debits and standing orders not yet entered in the cash book
- Bank Giro Credits (BACS payments) received from customers
- Dishonoured cheques returned by the bank
- Dividends or interest credited directly by the bank
The two-stage reconciliation process
CIE IGCSE Accounting questions typically require a two-stage approach:
Stage 1: Update the cash book
Only items unknown to the business (appearing on the bank statement but not in the cash book) require cash book entries. The procedure follows these steps:
- Identify items on the bank statement not recorded in the cash book
- Make debit entries for receipts (bank giro credits, interest received, dishonoured cheques returned to debtors)
- Make credit entries for payments (bank charges, direct debits, standing orders, dishonoured cheques)
- Calculate the updated cash book balance
Remember: timing differences (unpresented cheques and outstanding lodgements) do NOT appear in the cash book because they are already recorded there.
Stage 2: Prepare the Bank Reconciliation Statement
Starting from either the updated cash book balance or the bank statement balance, adjust for timing differences only:
Starting from cash book balance (debit):
- ADD unpresented cheques
- DEDUCT outstanding lodgements
- Equals bank statement balance
Starting from bank statement balance:
- DEDUCT unpresented cheques
- ADD outstanding lodgements
- Equals cash book balance
Overdraft vs credit balance considerations
Bank balances can be shown in two states:
Favourable balance (asset) — The business has money in the bank:
- Appears as a debit balance in the cash book
- Shown as a credit balance on the bank statement (the bank owes the business)
- Unpresented cheques reduce the bank statement balance
- Outstanding lodgements increase the bank statement balance
Overdraft (liability) — The business owes money to the bank:
- Appears as a credit balance in the cash book
- Shown as a debit balance on the bank statement
- Adjustments work in reverse: unpresented cheques increase the overdraft on the statement
- Outstanding lodgements decrease the overdraft on the statement
Many CIE IGCSE exam questions involve overdraft situations to test whether candidates truly understand the logic rather than memorising rules.
Dishonoured cheques — a common exam focus
Dishonoured cheques require careful treatment because they reverse a previous transaction:
Initial receipt of cheque:
- Debit: Bank (in cash book)
- Credit: Customer's account (receivable cleared)
When cheque is dishonoured:
- The business must reverse both entries
- Debit: Customer's account (debt reinstated)
- Credit: Bank (in updated cash book)
- The amount is then ADDED BACK to the customer's receivables ledger account
CIE examiners frequently test this because students confuse it with unpresented cheques.
Direct debits, standing orders, and automated payments
Modern banking involves numerous automated transactions:
Direct debits are variable amounts authorised by the business but controlled by the payee (insurance premiums, utility bills). They appear on the bank statement first.
Standing orders are fixed regular payments set up by the business (rent, loan repayments). The business should record these when due, but often they appear on the bank statement before being entered in the cash book.
Bank Giro Credits (BGC) or BACS payments are electronic transfers received from customers. These appear on the bank statement before the business identifies which customer paid.
All these items require cash book adjustment when preparing a bank reconciliation.
Worked examples
Example 1: Basic bank reconciliation with overdraft
The cash book of Ahmed's Business shows a credit balance (overdraft) of $3,200 on 30 June 2024. The bank statement shows a debit balance (overdraft) of $3,850 on the same date.
Investigation reveals:
- Bank charges of $45 on the bank statement not in the cash book
- A standing order for rent of $300 on the bank statement not in the cash book
- Cheques issued but not yet presented: $1,250
- Deposits paid in but not yet credited: $635
Required: (a) Update the cash book (4 marks) (b) Prepare the bank reconciliation statement (4 marks)
Solution:
(a) Updated Cash Book (Bank columns only)

Example 2: Dishonoured cheque scenario
Fatima Trading's cash book shows a debit balance of $8,400 on 31 March 2024. The bank statement shows a credit balance of $6,920.
The following items are discovered:
- A cheque for $600 received from customer James and deposited has been returned marked "insufficient funds"
- Bank interest received $180
- Cheques issued totalling $2,100 have not been presented
- A deposit of $950 paid in on 31 March does not appear on the bank statement
Required: Prepare the updated cash book and bank reconciliation statement (10 marks)
Solution:
Updated Cash Book (Bank columns only)
| Date | Details | Debit $ | Date | Details | Credit $ |

Note: The dishonoured cheque was already included in the original cash book balance, so it appears in the updated cash book as a reversal but does NOT appear in the bank reconciliation statement.
Example 3: Starting from bank statement balance
Omar Enterprises' bank statement shows a credit balance of $12,450 on 31 December 2024. The cash book (before adjustments) shows a debit balance of $11,200.
The following are identified:
- Direct debit for insurance $340

Common mistakes and how to avoid them
Mistake: Adjusting the cash book for unpresented cheques and outstanding lodgements. Correction: These timing differences are already recorded in the cash book. Only adjust the cash book for items appearing on the bank statement that the business did not know about (bank charges, direct debits, dishonoured cheques, bank giro credits).
Mistake: Treating dishonoured cheques as unpresented cheques. Correction: A dishonoured cheque was previously recorded as received, so it must be reversed in the updated cash book by crediting the bank account and debiting the customer's account. It does not appear in the bank reconciliation statement.
Mistake: Adding and subtracting incorrectly when dealing with overdrafts. Correction: When the cash book shows an overdraft (credit balance), unpresented cheques increase the bank statement overdraft, and outstanding lodgements decrease it. Draw up the reconciliation carefully, noting whether you're working with a debit or credit balance.
Mistake: Including the same item twice in both the cash book update and the reconciliation statement. Correction: Each item appears in only ONE place: either in the updated cash book OR in the bank reconciliation statement, never both. Use a checklist to tick off each item as you process it.
Mistake: Confusing debit and credit balances between the cash book and bank statement. Correction: A debit balance in the cash book (asset) corresponds to a credit balance on the bank statement (liability from the bank's perspective). The bank statement shows the business's account from the bank's viewpoint, so the positions are reversed.
Mistake: Incorrectly calculating the final balance when multiple adjustments are needed. Correction: Prepare a proper two-column cash book layout showing debits and credits separately, then total and balance. Do not attempt mental arithmetic with multiple items; show all workings for partial credit even if your final answer is incorrect.
Exam technique for Bank Reconciliation Statements
Command word recognition: Questions use "prepare," "update," or "draw up" for the cash book and "prepare a bank reconciliation statement" for the reconciliation. Each instruction requires a specific format—a two-column cash book with debit and credit entries, or a vertical reconciliation statement starting from one balance and arriving at the other.
Mark allocation patterns: Typically 1 mark per correct figure in the updated cash book (2-4 items = 2-4 marks) and 1 mark for the final balanced amount. The reconciliation statement awards 1 mark for starting balance, 1 mark per adjustment (unpresented cheques and outstanding lodgements), and 1 mark for the final balance. Always show headings and labels clearly.
Presentation requirements: The updated cash book must show proper double-entry format with date columns, details columns, and debit/credit money columns. Total both sides and show balance c/d and balance b/d. The bank reconciliation statement requires clear labels for each adjustment and uses either addition or subtraction format consistently.
Workings and partial credit: CIE mark schemes award method marks even when figures are incorrect. Show calculations for totals, label every figure clearly (e.g., "cheque no. 1847"), and ensure your reconciliation statement explicitly states which balance you started from and which balance you reached.
Quick revision summary
Bank Reconciliation Statements explain why the cash book and bank statement show different balances. Update the cash book for items unknown to the business (bank charges, direct debits, dishonoured cheques, bank giro credits). Prepare the reconciliation statement using timing differences only (unpresented cheques and outstanding lodgements). Start from either balance and adjust to reach the other. Unpresented cheques reduce the bank statement balance; outstanding lodgements increase it. Dishonoured cheques reverse previous receipts in the cash book. Always show full workings in proper format for maximum marks.
