This guide teaches sections 3.3 Correction of errors and 3.4 Bank reconciliation statements of Topic 3, Introduction to control processes, in the Pearson Edexcel International GCSE in Accounting (4AC1) specification, Issue 1 (October 2016). The specification does not split these sections into tiers. Topic 3 belongs to the content that Paper 1 draws on, and the specification says Paper 2 builds on topics 1 to 3. All amounts are in dollars.

Use the revision notes for quick recall and the practice questions to test yourself. See also the Edexcel IGCSE Accounting hub, the printable checklist and the free diagnostics.

3.4 b Understand the process of bank reconciliation The process
3.4 c Prepare a bank reconciliation statement Worked example

Two groups of error

A trial balance lists every ledger balance in a debit column and a credit column. If the totals agree, the arithmetic of double entry holds. It does not show that every entry is right. The specification does not name error types, so the usual names below are labels only. In an answer, describe the error in words as well.

Errors that do not affect the balancing. A debit and a credit of the same amount are still posted, so the totals still agree.

Error Meaning Example
Omission A transaction is left out completely A credit sale of 260 to M. Joshi is never recorded
Commission Right type of account, wrong account A receipt of 340 is credited to S. Okonkwo instead of S. Okoro
Principle Item put in the wrong class of account A delivery van costing 9,500 is debited to motor expenses
Original entry Wrong figure used in both entries An invoice for 1,260 is recorded as 1,620 in both accounts
Compensating Two errors of equal size on opposite sides cancel Wages overcast by 400 and rent received overcast by 400
Complete reversal Correct accounts, each on the wrong side A receipt of 520 debited to the customer and credited to bank

Errors that do affect the balancing. The two sides of the trial balance no longer agree.

  • A single-sided entry: only the debit or only the credit is posted.
  • Different amounts on the two sides: debit 380, credit 308.
  • Both entries on the same side: two debits, or two credits.
  • An addition error (casting error) in an account, or a balance carried down wrongly.
  • A balance copied to the trial balance wrongly or on the wrong side.

Method in steps for any error. Work out what was done. Work out what should have been done. Then write the entry that fixes the difference.

Journal entries to correct errors

A journal entry shows the account to debit, the account to credit, the amount, and a short narrative. Do not erase the original entry. Correct it with a new journal. The six corrections for the table above are:

Account Dr Cr
M. Joshi (omission) 260
Sales 260
Narrative: credit sale omitted from the books
S. Okonkwo (commission) 340
S. Okoro 340
Narrative: receipt posted to the wrong customer
Motor vehicles (principle) 9,500
Motor expenses 9,500
Narrative: van is capital expenditure
Trade payables, supplier (original entry) 360
Purchases 360
Narrative: invoice of 1,260 recorded as 1,620
Rent received (compensating) 400
Wages 400
Narrative: both accounts overcast by 400
Bank (complete reversal) 1,040
E. Dunn 1,040
Narrative: receipt of 520 posted to the wrong sides

The reversal needs 1,040: the first 520 cancels the wrong entry and the second 520 makes the right one. In the original entry error, only the excess of 360 is corrected.

An invoice of 1,260 recorded as 1,620 needs a journal for only 360. A receipt of 520 posted to the wrong sides swings bank from minus 520 to plus 520, so the journal is 1,040.
The journal is the excess for an original entry error but double for a complete reversal.

The suspense account

A suspense account is a temporary ledger account. If the trial balance does not agree, the difference goes into it so the totals match for now. The aim is to find the errors, correct them and clear the account to nil. A trial balance with a higher credit total gets the difference as a debit in suspense. A higher debit total gets a credit.

Worked example. Kelsby Bakery’s trial balance at 30 June 2026 is below.

Account Dr Cr
Premises 52,000
Ovens and equipment 6,800
Inventory at 1 July 2025 8,400
Purchases 41,200
Rent 308
Wages 12,600
Trade receivables 6,900
Bank 4,120
Drawings 9,000
Sales 74,000
Trade payables 6,200
Loan 15,000
Capital 45,750
Discount received 710
Totals 141,328 141,660

The credit side is 332 higher, so 332 is debited to a suspense account. The totals then both read 141,660. These errors are found.

  1. A credit sale of 450 to Ellis Ltd was credited to sales. The debit in Ellis’s account was never posted.
  2. Rent of 380 was paid by bank. The bank entry is right, but the rent account was debited with 308.
  3. Discount received of 95 was posted to the debit side of the discount received account.
  4. A computer costing 1,200 was debited to purchases.

Errors 1 to 3 affect the trial balance. Error 4 does not: it is an error of principle.

Error 1 is a single-sided entry. Debit Trade receivables (Ellis Ltd) 450 and credit Suspense 450. Error 2 is a different-amounts error. Debit Rent 72 and credit Suspense 72. Error 3 puts a credit item on the debit side, so the account is wrong by twice 95. Debit Suspense 190 and credit Discount received 190. For error 4, debit Office equipment 1,200 and credit Purchases 1,200. Suspense is not involved.

Suspense account
Difference per trial balance 332 Trade receivables (Ellis Ltd) 450
Discount received 190 Rent 72
522 522

The account clears to nil, which suggests all the errors have been found. A suspense account that does not clear tells you at least one error is still hidden.

Kelsby Bakery trial balance: debit column 141,328, credit column 141,660, so the credit side is 332 higher. The 332 is debited to suspense so both columns read 141,660.
A higher credit total puts the difference as a debit in suspense.
Suspense debit side: difference 332 and discount received 190 (522). Credit side: trade receivables 450 and rent 72 (522). It clears to nil; the error of principle never passes through it.
The suspense account clears to nil once the three trial balance errors are corrected.

Why reconcile

A bank statement is the bank’s own record of the account. The business’s cash book (bank column) is the business’s record of the same account. The two should tell the same story, yet at a given date the balances usually differ. A bank reconciliation statement explains the difference.

Its purposes are to:

  • check the accuracy of both records and find mistakes made by the business or the bank;
  • spot entries on the statement that are missing from the cash book, such as charges;
  • detect fraud or unauthorised payments;
  • show the true bank balance the business can rely on, once timing differences are understood.
A cash book written by the business and a bank statement written by the bank are compared line by line. Five purposes: confirm payments reached the bank, find unrecorded bank entries, spot mistakes, show how much can safely be spent, detect unauthorised payments.
The bank statement is an independent check on the cash book.

The process

Compare the cash book with the statement line by line, ticking items that appear in both. Then sort what is left.

Item left over Cause What you do
On the statement, not the cash book Credit transfers, bank interest, bank charges, standing orders, direct debits, dishonoured cheques Update the cash book
In the cash book wrongly Error by the business Correct the cash book
In the cash book, not the statement Unpresented cheques, uncredited lodgements (banked but not yet shown) Put on the reconciliation statement
On the statement wrongly Bank error Put on the reconciliation statement and tell the bank

Update the cash book first. Only the timing items, and any bank error, are left for the reconciliation statement. A statement shows a credit balance when the bank holds money for you, because it is a liability of the bank. Your cash book shows the same position as a debit.

Ten Halvorn differences: seven are entered in the cash book (700, 12, 45, 120, 300, 230 and the 90 cheque correction); three timing items (380, 215 and 1,100) go on the reconciliation only.
Sort each difference into update the cash book or reconciliation only.
Bank charges, interest paid, direct debit and standing order are credits; bank interest received and credit transfer are debits. Outstanding bankings are added, unpresented cheques deducted and bank errors corrected on the reconciliation only.
Items the bank knows first go in the cash book; items the business knows first only change the reconciliation.
Debit side (money in): credit transfer, interest received, error too little received or too much paid. Credit side (money out): charges, interest paid, direct debit, standing order, error too much received or too little paid. Unpresented cheques and uncredited deposits are never entered.
Which side each updating item goes on, and what must never be entered.

Worked example: Halvorn Cycles

At 31 October 2026 the cash book (bank column) of Halvorn Cycles shows a debit balance of 3,640. Comparing it with the bank statement gives these differences.

  • Credit transfer from a customer, 700, not in the cash book.
  • Bank interest received, 12, not in the cash book.
  • Bank charges, 45, not in the cash book.
  • Direct debit for insurance, 120, not in the cash book.
  • Standing order for a loan repayment, 300, not in the cash book.
  • A customer’s cheque for 230 was dishonoured and is on the statement only.
  • A cheque to a supplier for 450 was entered in the cash book as 540.
  • Cheques of 380 and 215 to suppliers have not been presented.
  • A lodgement of 1,100 made on 31 October is not yet on the statement.

Step 1: update the cash book. The error understated the balance by 90, so it is added back.

Cash book (bank)
Balance b/d 3,640 Bank charges 45
Credit transfer 700 Direct debit 120
Bank interest 12 Standing order 300
Correction: cheque error 90 Dishonoured cheque 230
Balance c/d 3,747
4,442 4,442

Step 2: prepare the bank reconciliation statement.

Bank reconciliation statement at 31 October 2026
Balance per updated cash book 3,747
Add: unpresented cheques (380 + 215) 595
4,342
Less: uncredited lodgement 1,100
Balance per bank statement 3,242

The reverse route gives the same result: 3,242 + 1,100 − 595 = 3,747. Give the statement a heading, a date and a labelled final line.

Cash book 3,640 plus 700, 12 and 90, less 45, 120, 300 and 230 gives an updated balance of 3,747.
Update the cash book first: 3,640 becomes 3,747.
From 3,747, add unpresented cheques 595 and deduct the uncredited lodgement 1,100 to reach the statement balance of 3,242. The reverse route returns 3,747.
Add unpresented cheques, deduct the lodgement and the statement balance of 3,242 follows.

Common errors

  • Putting the suspense difference on the wrong side. Check which total is higher, then put the difference on the side that is lower.
  • Posting a one-sided correction to suspense in the wrong direction. Say whether suspense was debited or credited when the error was made, then reverse it.
  • Journalising an error of principle without clearing the original wrong account.
  • Treating a compensating error as if it needs suspense.
  • Using the single amount to correct a complete reversal, when double is needed.
  • Adjusting the cash book for unpresented cheques. They belong on the reconciliation only.
  • Adding a dishonoured cheque to the cash book. It reduces the balance.
  • Starting the reconciliation from the unadjusted cash book balance.

Next, try the practice questions.

Frequently asked questions

What is a bank reconciliation statement in Edexcel IGCSE Accounting? A bank reconciliation statement explains the difference between the balance in the cash book (bank column) and the balance on the bank statement at a given date. It checks both records, finds missing entries such as bank charges, and helps detect fraud.

Why does a bank statement show a credit balance when the business has money in the bank? The bank statement is the bank’s record, and money held for the business is a liability of the bank, so it shows as a credit. The business’s cash book shows the same position as a debit balance.

Which items are entered in the cash book before preparing the reconciliation? Items on the bank statement but missing from the cash book, such as credit transfers, interest, bank charges, direct debits, standing orders and dishonoured cheques, are entered in the cash book first, along with any cash book errors. Only timing items and bank errors are left for the reconciliation statement.

What is a suspense account? A suspense account is a temporary ledger account that holds the difference when a trial balance does not agree. Once the errors are found and corrected, the account should clear to nil.

Which errors do not affect the trial balance? Errors of omission, commission, principle, original entry, compensating errors and complete reversals leave the trial balance agreeing, because equal debits and credits are still posted. The 4AC1 specification does not name these types, so describe each error in words too.
