Why it happens: Over-correcting. How to avoid it: Only adjust both for an error that genuinely affected both (e.g. a completely omitted transaction). Source: 9706 Examiner Reports

Why is "Adding when you should deduct in the schedule" a common mistake in Reconciliation Statements Between Control & Ledger Accounts?

Why it happens: Confusing overstated and understated. How to avoid it: ADD omitted/understated balances; DEDUCT overstated balances from the original list total. Source: 9706 Examiner Reports

Why is "Putting a control-account correction on the wrong side" a common mistake in Reconciliation Statements Between Control & Ledger Accounts?

Why it happens: Forgetting the item's normal side. How to avoid it: Apply the same sides as in the control account: e.g. an omitted contra/irrecoverable debt is a credit (reduces receivables). Source: 9706 Examiner Reports

Reconciling Control Accounts with Ledger Balances — Cambridge AS & A Level Accounting 9706 Study Notes (2026-2028)

What to do when the control account and the ledger total disagree. Learn to classify each error — does it affect the control account, the schedule of individual balances, or both? — then prepare an amended control account and a schedule of corrected ledger balances so the two finally agree.

At a glance

The control account balance should equal the total of the individual ledger balances; when they disagree, errors must be found.
Errors in books of prime entry totals (e.g. an overcast journal) affect the control account.
Errors in individual accounts (e.g. a balance miscalculated or omitted) affect the schedule (list) of ledger balances.
Some errors affect both; some affect neither total (and so do not cause the disagreement).
Two outputs: an amended control account and a schedule of corrected ledger balances.
When corrected, the amended control balance = corrected schedule total.
The first step is always to classify each error by which figure it affects.

What you’ll learn

Mapped to the Cambridge International A Level 9706 syllabus (2026-2028).

1.4.4 — Prepare reconciliation statements between control account balances and ledger balances.
1.4.4 — Understand the effects on the financial statements of the correction of errors.
1.4.4 — Understand the benefits and limitations of control accounts.

Classify each error first

Decide whether each error affects the control account, the schedule, both or neither.

When the control account and the ledger total disagree, the cause is one or more errors. The key skill is to classify each error by which figure it affects:

Type of error	Affects
Wrong total from a book of prime entry (e.g. sales journal overcast)	Control account
Item omitted from the control account (e.g. a contra)	Control account
An individual account miscalculated or balanced wrongly	Schedule of balances
A balance omitted from the list of individual balances	Schedule of balances
A transaction completely omitted from the books	Both (or neither, if symmetric)
A sale posted to the wrong customer	Neither total (commission — totals unchanged)

The discipline: never adjust both records for the same error unless it genuinely affected both. Decide for each error which figure is wrong, and adjust only that one.

Book-of-prime-entry total errors → the control account.
Individual account / list errors → the schedule of balances.
Some errors affect both; wrong-customer errors affect neither total.
Classify each error before adjusting anything.

See the full worked example for reconciliation statements between control & ledger accounts →

Amending the control account

Adjust the control account only for errors in the totals it was built from.

The control account is built from the books of prime entry totals, so it is amended for errors in those totals (or items omitted from it):

A journal overcast/undercast (e.g. sales journal overcast by $200) → adjust the relevant figure in the control account.
An item omitted from the control account (e.g. a contra, irrecoverable debt or dishonoured cheque not entered) → add it.
A figure entered on the wrong side of the control account → correct it.

Re-balance the control account to find the amended (corrected) balance. This is the figure that should equal the corrected schedule total.

Amend the control account for errors in the books of prime entry totals.
Add items omitted from the control account (contra, irrecoverable debts, etc.).
Correct any figure on the wrong side.
Re-balance to find the amended control balance.

See the full worked example for reconciliation statements between control & ledger accounts →

The schedule of corrected ledger balances

Start from the original list total and adjust for errors in the individual accounts.

The schedule (list) of individual balances is corrected separately. Start from the original total of the individual balances and add or deduct the effect of each error that affected an individual account:

Schedule of corrected balances	$
Total per original list	X
Add: a balance understated / omitted	X
Less: a balance overstated	(X)
Corrected total	X

Typical schedule errors:

a customer's balance added up wrongly (overstated/understated);
a balance omitted from the list;
a balance entered as the wrong figure in the list.

When done correctly, the corrected schedule total equals the amended control account balance — the two now reconcile.

Start from the original total of the individual balances.
Add understated/omitted balances; deduct overstated ones.
Adjust only for errors in the individual accounts/list.
The corrected total should equal the amended control balance.

See the full worked example for reconciliation statements between control & ledger accounts →

Proving the two agree

The amended control balance must equal the corrected schedule total.

The reconciliation is complete only when the amended control account balance equals the corrected schedule total. If they still differ, an error remains to be found.

A typical sequence:

Classify each error (control / schedule / both / neither).
Amend the control account for its errors → amended balance.
Correct the schedule of individual balances → corrected total.
Check they agree.

This process both localises and corrects errors and confirms the trade receivables (or payables) figure that goes into the financial statements.

Reconciliation is complete when control balance = schedule total.
If they still differ, an error remains.
Sequence: classify → amend control → correct schedule → check.
Confirms the receivables/payables figure for the financial statements.

Amend the control account for book-of-prime-entry total errors and omitted items.
Correct the schedule (list) for errors in the individual accounts.
The amended control balance must equal the corrected schedule total.

Step-by-step worked examples — Reconciliation Statements Between Control & Ledger Accounts

Step-by-step solutions to past-paper-style questions on reconciliation statements between control & ledger accounts, written exactly the way a tutor would explain them at the board.

Question type:

1Control account or schedule? (5 marks)
Getting startedIdentify & classify• 9706 Paper 2 style• reconciliation, AO2
Question
State whether each error affects the control account (C), the schedule of ledger balances (S), or both (B): (i) the sales journal was overcast by $300; (ii) a customer's balance was added up as$ 50 too much; (iii) a contra was omitted from the control account; (iv) a balance of $400 was omitted from the list of debtors; (v) a credit sale of$ 200 was completely omitted from the books. (5 marks)
Step-by-step solution
1. Step 1
  (i) Journal total error → C.
2. Step 2
  (ii) Individual account miscalculated → S.
3. Step 3
  (iii) Omitted from the control account → C.
4. Step 4
  (iv) Omitted from the list → S.
5. Step 5
  (v) Omitted from both records → B.
Answer
(i) C; (ii) S; (iii) C; (iv) S; (v) B.
Examiner tip
Book-of-prime-entry totals → control; individual accounts/list → schedule.
2Amend the control account (6 marks)
Building confidenceMulti-step problem• control account, AO2
Question
A sales ledger control account shows a balance of $50,000. It is then found that (a) the sales journal was overcast by$ 400 and (b) a contra of $700 had been omitted. Calculate the amended control account balance. (6 marks)
Step-by-step solution
1. Step 1
  (a) Sales journal overcast → credit sales (debit) too high by 400 → reduce by 400.
2. Step 2
  (b) Contra omitted → a contra is a credit (reduces receivables) → reduce by 700.
3. Step 3
  Amended control balance = 50,000 − 400 − 700 = $48,900.
Answer
Amended control account balance = $48,900.
Examiner tip
Both errors reduce the control balance: overcast sales and an omitted contra.
3Schedule of corrected balances (6 marks)
Building confidenceMulti-step problem• schedule, AO2
Question
The list of individual debtor balances totals $49,300. It is found that (a) a balance of$ 400 was omitted from the list and (b) a customer's balance was overstated by $800. Prepare a schedule of corrected balances. (6 marks)
Step-by-step solution
1. Step 1
  Start with the original total $49,300.
2. Step 2
  (a) Balance omitted → add $400.
3. Step 3
  (b) Balance overstated → deduct $800.
4. Step 4
  Corrected total = 49,300 + 400 − 800 = $48,900.
Answer
Corrected schedule total = $48,900.
Examiner tip
Add omitted/understated balances; deduct overstated ones.
4Prove the two agree (6 marks)
Building confidenceMulti-step problem• reconciliation, AO2
Question
After corrections, the amended control account balance is $48,900 and the corrected schedule of balances totals$ 48,900. Explain what this shows and what would be concluded if they had differed. (6 marks)
Step-by-step solution
1. Step 1
  The two figures are equal ($48,900).
2. Step 2
  This shows the control account and the individual ledger balances now reconcile — the errors have all been found and corrected.
3. Step 3
  The $48,900 is the trade receivables figure for the financial statements.
4. Step 4
  If they had differed, it would mean another error remains to be found and corrected.
Answer
Equal balances confirm the records reconcile and give the receivables figure; a difference would mean another error remains.
Examiner tip
Reconciliation is complete only when the two agree.
5Full reconciliation, both records (7 marks)
StretchMulti-step problem• reconciliation, AO2
Question
Control account balance $62,000; list of debtor balances total$ 61,250. Errors: (a) sales journal undercast by $500 (control); (b) a customer balance overstated by$ 1,200 (schedule); (c) a discount allowed of $50 omitted from the control account (control). Prepare the amended control balance and the corrected schedule total, and check they agree. (7 marks)
Step-by-step solution
1. Step 1
  Control: (a) undercast sales → add 500; (c) discount allowed omitted (a credit) → deduct 50.
2. Step 2
  Amended control = 62,000 + 500 − 50 = $62,450.
3. Step 3
  Schedule: (b) balance overstated → deduct 1,200.
4. Step 4
  Corrected schedule = 61,250 − 1,200 = $60,050.
5. Step 5
  These do not agree (62,450 ≠ 60,050) — but only the listed errors were given; a remaining difference of $2,400 would mean further errors to find.
6. Step 6
  (In an exam, the given errors are designed so the two agree; always check and state if they do not.)
Answer
Amended control $62,450; corrected schedule$ 60,050 — a remaining $2,400 difference signals further errors.
Examiner tip
Adjust the correct record for each error; if the two still differ, state that an error remains.
6An error affecting both records (5 marks)
StretchMulti-step problem• reconciliation, AO2
Question
A credit sale of $600 to a customer was completely omitted from the books. Explain how this is dealt with in reconciling the control account and the schedule. (5 marks)
Step-by-step solution
1. Step 1
  An omitted credit sale affects both the sales journal total (control) and the customer's account (schedule).
2. Step 2
  Control account: add the $600 credit sale (debit) → increases the control balance by 600.
3. Step 3
  Schedule: add the $600 to the customer's balance → increases the schedule total by 600.
4. Step 4
  Because both totals rise by $600, they stay in agreement — this error does not cause a disagreement.
5. Step 5
  (It does, however, understate receivables until corrected.)
Answer
Add $600 to both the control account and the schedule; both rise equally, so they remain in agreement (but receivables were understated).
Examiner tip
A symmetric omission affects both records equally, so it does not cause a difference.
7An error affecting neither total (4 marks)
StretchWord problem• reconciliation, AO2
Question
A credit sale of $350 was posted to the wrong customer's account. Explain why this does not cause the control account and the schedule to disagree. (4 marks)
Step-by-step solution
1. Step 1
  The sale was still recorded in the sales journal total, so the control account is unaffected.
2. Step 2
  It was still posted to a customer account (the wrong one), so the total of the individual balances is unchanged.
3. Step 3
  Both totals are therefore correct in total, so they still agree.
4. Step 4
  This is an error of commission — it does not affect either total (though the individual accounts are wrong).
Answer
Both totals are unchanged (the sale is in the journal total and posted to some customer), so they still agree — an error of commission.
Examiner tip
Wrong-customer errors leave both totals correct, so no disagreement arises.
8Reconcile a purchases ledger (6 marks)
StretchMulti-step problem• control account, AO2
Question
A purchases ledger control account shows $38,000; the list of creditor balances totals$ 38,650. Errors: (a) the purchases journal was overcast by $300 (control); (b) a creditor balance was understated by$ 350 (schedule). Prepare the amended control balance and corrected schedule total, and check they agree. (6 marks)
Step-by-step solution
1. Step 1
  Control: (a) purchases overcast → credit purchases (credit) too high by 300 → reduce by 300.
2. Step 2
  Amended control = 38,000 − 300 = $37,700.
3. Step 3
  Schedule: (b) creditor understated → add 350.
4. Step 4
  Corrected schedule = 38,650 + 350 = $39,000.
5. Step 5
  These differ (37,700 vs 39,000) by $1,300 — given only these two errors, a further error must remain to make them agree.
Answer
Amended control $37,700; corrected schedule$ 39,000 — a $1,300 gap indicates a further error.
Examiner tip
Reduce the control for an overcast journal; add to the schedule for an understated balance.
9Which figure for the SOFP? (4 marks)
StretchWord problem• reconciliation, AO2
Question
After reconciliation, the amended sales ledger control balance equals the corrected schedule total at $54,200. State which figure is shown as trade receivables in the statement of financial position and why. (4 marks)
Step-by-step solution
1. Step 1
  The reconciled figure $54,200 is shown as trade receivables.
2. Step 2
  Because the amended control balance equals the corrected schedule total, both records now agree.
3. Step 3
  This agreed figure is the true amount owed by customers.
4. Step 4
  So it is the reliable receivables figure for the statement of financial position.
Answer
The reconciled $54,200 — the control and schedule now agree, giving the true receivables figure.
Examiner tip
Use the reconciled figure (control = schedule) for the SOFP.
10Limitations of the reconciliation (5 marks)
StretchWord problem• limitations, AO3
Question
Explain why reconciling the control account to the schedule of balances does not guarantee the ledger is completely correct. (5 marks)
Step-by-step solution
1. Step 1
  Some errors leave both totals unchanged — e.g. a sale posted to the wrong customer (commission).
2. Step 2
  The control and schedule would still agree, hiding the error in the individual accounts.
3. Step 3
  Compensating errors in the individual accounts could also cancel out.
4. Step 4
  The reconciliation checks the total, not whether each customer's balance is correct.
5. Step 5
  So agreement gives reasonable, not absolute, assurance.
Answer
Errors that don't change either total (wrong customer, compensating errors) leave the two agreeing; it checks totals, not individual balances.
Examiner tip
The limitation: agreement of totals does not prove each individual balance is right.

Model Answers — Reconciliation Statements Between Control & Ledger Accounts

High-scoring sample answers for reconciliation statements between control & ledger accounts on the Cambridge IGCSE paper, with examiner-style notes mapping each response to the mark scheme and assessment objectives.

Question 1
9706 Paper 2 style4 marks
Q (4 marks). State whether each error affects the control account, the schedule of balances, or both: (a) the sales journal was undercast by $500; (b) a debtor's balance was overstated by$ 300; (c) a balance was omitted from the list of debtors; (d) an irrecoverable debt was omitted from the control account.
Model answer
(a) Control account (a book-of-prime-entry total error). (b) Schedule of balances (an individual account error). (c) Schedule of balances (an error in the list). (d) Control account (item omitted from the control account).
Why this scores
Marking (point-based, 4). 1 mark each. Totals → control; individual accounts/list → schedule.
Question 2
9706 Paper 2 style5 marks
Q (5 marks). A sales ledger control account shows $44,000. It is found that the sales journal was overcast by$ 250 and a contra of $600 was omitted. Calculate the amended control account balance.
Model answer
Sales journal overcast by $250 → credit sales too high → reduce by $250.

Contra omitted → a contra is a credit (reduces receivables) → reduce by $600.

Amended control balance = 44,000 − 250 − 600 = $43,150.
Why this scores
Marking (point-based, 5). Overcast sales − $250 (2); omitted contra −$ 600 (2); amended $43,150 (1).
Question 3
9706 Paper 2 style5 marks
Q (5 marks). The list of debtor balances totals $43,800. It is found that (a) a balance of$ 350 was omitted from the list and (b) a customer's balance was overstated by $1,000. Prepare a schedule of corrected balances.
Model answer
Schedule of corrected balances

$
Total per original list 43 800
Add: balance omitted 350
Less: balance overstated (1 000)
Corrected total 43 150
Why this scores
Marking (point-based, 5). Start $43,800 (1); add omitted$ 350 (1.5); deduct overstated $1,000 (1.5); corrected$ 43,150 (1).
Question 4
9706 Paper 2/3 style6 marks
Q (6 marks). A sales ledger control account shows $44,000 and the list of debtor balances totals$ 43,800. Errors found: (a) sales journal overcast by $250 and a contra of$ 600 omitted (both control); (b) a balance of $350 omitted from the list and a balance overstated by$ 1,000 (both schedule). Calculate the amended control balance and the corrected schedule total, and state whether they agree.
Model answer
Amended control account: 44,000 − 250 (overcast) − 600 (contra) = $43,150.

Corrected schedule: 43,800 + 350 (omitted) − 1,000 (overstated) = $43,150.

The amended control balance ($43,150) equals the corrected schedule total ($43,150), so the two now reconcile — all the errors have been found.
Why this scores
Marking (point-based, 6). Amended control $43,150 (2); corrected schedule$ 43,150 (2); statement that they agree/reconcile (2).
Question 5
9706 Paper 3 style6 marks
Q (6 marks). A purchases ledger control account shows $52,000 and the list of creditor balances totals$ 52,900. Errors: (a) the purchases journal was overcast by $400 (control); (b) a discount received of$ 200 was omitted from the control account (control); (c) a creditor's balance was overstated by $700 (schedule). Calculate the amended control balance and the corrected schedule total.
Model answer
Amended control account:

(a) Purchases overcast → credit purchases too high → reduce by $400.

(b) Discount received omitted → a debit (reduces payables) → reduce by $200.

Amended control = 52,000 − 400 − 200 = $51,400.

Corrected schedule:

(c) Creditor overstated → deduct $700.

Corrected schedule = 52,900 − 700 = $52,200.

These differ by $800, so (given only these errors) a further error remains to be found before the two agree.
Why this scores
Marking (point-based, 6). Amended control $51,400 (3); corrected schedule$ 52,200 (2); recognise remaining difference (1).
Question 6
9706 Paper 3 style5 marks
Q (5 marks). Explain how a credit sale of $500 that was completely omitted from the books affects the reconciliation between the control account and the schedule of balances.
Model answer
A completely omitted credit sale affects both records:

the sales journal total is understated, so the control account is understated by $500; and

the customer's account was never posted, so the schedule of individual balances is also understated by $500.

When corrected, both the control account and the schedule are increased by $500. Because they change by the same amount, they stay in agreement — so this error does not cause a difference between them. (It does, however, understate trade receivables until the omission is corrected.)
Why this scores
Marking (point-based, 5). Affects both records (~1.5); both increased by $500 (~2); stay in agreement / receivables understated (~1.5).
Question 7
9706 Paper 2/3 style4 marks
Q (4 marks). Explain why posting a credit sale to the wrong customer does not cause the control account and the schedule of balances to disagree.
Model answer
The credit sale was still included in the sales journal total, so the control account is correct in total.

It was also still posted to a customer account (just the wrong one), so the total of the individual balances is unchanged — one account is too high and another too low by the same amount.

Because both totals remain correct, the control account and the schedule still agree. This is an error of commission: it makes the individual accounts wrong, but it does not affect either total, so the reconciliation does not reveal it.
Why this scores
Marking (point-based, 4). Control unaffected (in the journal total) (~1.5); schedule total unchanged (posted to a customer) (~1.5); error of commission, totals still agree (~1).
Question 8
9706 Paper 3 evaluation style6 marks
Q (6 marks). Discuss the extent to which reconciling the control account with the schedule of balances ensures the sales ledger is accurate.
Model answer
What the reconciliation achieves. When the amended control account balance equals the corrected schedule total, it confirms that the books of prime entry totals and the individual balances are consistent, and it localises and corrects the errors that caused any disagreement. This gives a reliable trade receivables figure for the financial statements.

Why it is not a complete guarantee.

Errors that leave both totals unchanged — such as a sale posted to the wrong customer (commission) — leave the two agreeing despite the individual accounts being wrong.

Compensating errors within the individual accounts could cancel out.

The reconciliation checks the totals, not whether each customer's balance is correct.

It could be defeated by collusion.

Conclusion. Reconciling the control account with the schedule is a valuable check that detects and corrects many errors and confirms the receivables total, but it gives reasonable, not absolute, assurance — some errors within the ledger can remain undetected, so it should be combined with other checks (e.g. statements sent to customers, verification).
Why this scores
Marking (point-based, ~6). What it achieves (consistency/localise/receivables figure) (~2.5); limitations (wrong customer / compensating / totals not individuals) (~2.5); conclusion reasonable-not-absolute (~1).
Question 9
9706 Paper 2 style2 marks
Q (2 marks). After a successful reconciliation, the amended control balance and the corrected schedule total both equal $61,500. State what this figure represents and where it appears.
Model answer
It represents the trade receivables (the total amount owed by credit customers), and it appears as a current asset in the statement of financial position.
Why this scores
Marking (point-based, 2). Trade receivables (1); current asset in the SOFP (1).
Question 10
9706 Paper 2/3 style4 marks
Q (4 marks). Describe the steps a business should take to reconcile a control account that does not agree with the total of the individual ledger balances.
Model answer
Classify each error by which figure it affects — the control account, the schedule of individual balances, both, or neither.

Amend the control account for errors in the books of prime entry totals and any items omitted from it, to find the amended balance.

Correct the schedule of individual balances for errors in the individual accounts/list, to find the corrected total.

Check that the amended control balance equals the corrected schedule total; if not, a further error remains to be found.
Why this scores
Marking (point-based, 4). Classify (1); amend control (1); correct schedule (1); check they agree (1).

Common Mistakes and Misconceptions — Reconciliation Statements Between Control & Ledger Accounts

The traps other students keep falling into on reconciliation statements between control & ledger accounts questions — taken from recent Cambridge IGCSE examiner reports and mark schemes — and how to avoid them.

✕Adjusting the wrong record for an error
9706 Examiner Reports
Why it happens
Not classifying the error first.
How to avoid it
Book-of-prime-entry total errors → the CONTROL ACCOUNT; individual account/list errors → the SCHEDULE. Decide which figure is wrong.
✕Adjusting both records for an error that affects only one
9706 Examiner Reports
Why it happens
Over-correcting.
How to avoid it
Only adjust both for an error that genuinely affected both (e.g. a completely omitted transaction).
✕Adding when you should deduct in the schedule
9706 Examiner Reports
Why it happens
Confusing overstated and understated.
How to avoid it
ADD omitted/understated balances; DEDUCT overstated balances from the original list total.
✕Putting a control-account correction on the wrong side
9706 Examiner Reports
Why it happens
Forgetting the item's normal side.
