The concepts behind bank reconciliation are simple to state and easy to mix up under exam pressure: which side gets adjusted, which items need a journal entry, and which ones just resolve themselves once the bank catches up. The questions below are grouped by the kind of discrepancy they test – timing differences, NSF checks, bank versus book errors, the adjusting entries a reconciliation produces, and the process itself – so a specific weak spot can be drilled directly rather than working through everything from the top every time. For the full procedure these questions assume, see bank reconciliation explained.
Timing Differences: Outstanding Checks and Deposits in Transit
1. What is an outstanding check, and which side of the reconciliation does it adjust? An outstanding check has been written and recorded in the company's own books but has not yet been presented to the bank for payment, so it has not cleared and does not yet appear on the bank statement. It is subtracted from the bank balance during reconciliation, because the bank's ending balance is temporarily overstated relative to the true cash position until the check clears.
2. What is a deposit in transit, and how is it treated? A deposit in transit has been recorded in the company's books but reached the bank too late to appear on the current statement – made after the bank's daily cutoff, for example, or mailed near month-end. It is added to the bank balance during reconciliation, since the bank statement is temporarily understated relative to the true cash position.
3. A hypothetical company's bank statement shows an ending balance of $22,000. There is one deposit in transit of $1,800 and one outstanding check of $950. What is the adjusted bank balance? $22,000 + $1,800 − $950 = $22,850. That figure is the true cash position from the bank side, which should equal the adjusted book balance once every book-side item is applied.
4. Why don't outstanding checks and deposits in transit require a journal entry? Because the company's own books already recorded both transactions correctly on the date they occurred. The gap exists only between the books and the bank statement, not within the books themselves, so no correcting entry is needed – the item simply clears on its own once the bank processes it, usually within the next reconciliation period.
NSF Checks
5. What does NSF mean, and how does it affect a reconciliation? NSF stands for non-sufficient funds: a customer's check that the company deposited and initially recorded as cash received, which then bounced because the payer's account didn't have enough money to cover it. Because the cash never actually arrived, the NSF amount is subtracted from the book balance – this is a books-side item, since the books recorded a cash receipt that did not, in the end, happen.
6. What journal entry records an NSF check discovered during reconciliation? The original entry recorded a debit to Cash and a credit to Accounts Receivable (or Sales) when the check was first deposited. The reversing entry undoes the cash side: debit Accounts Receivable, credit Cash, for the amount of the bounced check – effectively restoring the customer's balance as still owed, since the payment did not go through.
7. If the bank also charges an NSF fee, is that the same adjustment as the bounced check itself? No, they are two separate book-side items. The NSF check reverses the cash the company thought it had received. The NSF fee is a new expense the bank charged for processing the bounced item, recorded with its own entry: debit Bank Fees Expense, credit Cash. Both reduce the book balance, but they correct two different things.
Bank Errors vs. Book Errors
8. How do you tell whether a discrepancy is a bank error or a company error? Trace the item back to its source. If it matches a transaction the company itself recorded incorrectly – the wrong amount, a duplicate entry, a transaction posted to the wrong account – it's a company (book) error, corrected on the books side. If the item doesn't match anything in the company's own records at all, or the bank's figure for a shared transaction differs from what was actually written or deposited, it's a bank error, corrected on the bank side after the bank confirms it.
9. A bank error is confirmed: the bank recorded a company's deposit at $1,200 when the actual deposit slip shows $2,100. What correction is made, and does it require a journal entry? This is corrected on the bank side of the reconciliation by adding the missing $900 to the bank balance, and the bank should be notified so it fixes its own record. No journal entry is needed, because the company's books already show the correct $2,100 – the books were never wrong.
10. A company recorded a check for $980 when the actual amount, per the check itself, was $890 – a hypothetical transposition error. How is this corrected? This is a book error, since the mistake originated in the company's own recording. It's corrected on the books side of the reconciliation by adjusting the book balance for the $90 difference, and it requires a journal entry to correct whichever account was originally debited or credited for the wrong amount.
Adjusting Journal Entries From a Reconciliation
11. As a general rule, which reconciling items need a journal entry and which don't? Bank-side items – outstanding checks, deposits in transit, and confirmed bank errors – don't need a journal entry, because the company's books were already correct; the bank simply hasn't caught up or made its own error. Book-side items – bank fees, interest earned, NSF checks, bank credit or debit memos, and confirmed company errors – do need a journal entry, because the books are missing something or contain a mistake that the reconciliation just uncovered.
12. What is the journal entry for a bank service charge discovered during reconciliation? Debit Bank Fees Expense, credit Cash, for the amount of the charge. The entry reduces the book cash balance to match the fee the bank already deducted, and it recognizes the fee as an expense for the period.
13. What is the journal entry for interest income shown on the bank statement but not yet recorded in the books? Debit Cash, credit Interest Income, for the amount earned. This is one of the few book-side adjustments that increases rather than decreases the book balance, since the bank paid the company money it hadn't yet recorded receiving.
Reconciliation Frequency and Process
14. How often should a business reconcile its bank account? Monthly is the common baseline for a smaller business with moderate transaction volume. Businesses with higher transaction volume, multiple accounts, multi-currency activity, or elevated fraud risk often reconcile weekly or daily, since a longer gap between reconciliations means more transactions to untangle if a discrepancy turns up.
15. What happens if a company skips reconciliation for several months? Discrepancies accumulate rather than disappear, and the opening balance for the eventual reconciliation may itself already be wrong, which forces someone to trace several months of transactions at once instead of one manageable period. It also delays exactly the kind of fraud detection reconciliation is meant to provide – an unauthorized withdrawal sitting unnoticed for months is far harder to trace than one caught within weeks.
16. Who should perform the reconciliation, and why does that specific detail matter? Ideally someone who does not also handle cash receipts, deposits, or disbursements. The Committee of Sponsoring Organizations of the Treadway Commission (COSO) frames this kind of control as more than a compliance checkbox, noting that "effective internal controls are good for business" and carry value beyond compliance and reporting (COSO, checked 2026-09-30) – segregating reconciliation from cash handling is what gives the control its actual power to catch a problem rather than simply document one after the fact.
A Note on Documentation
Every reconciling item discussed above – cleared or outstanding, timing or error, bank-side or book-side – should be traceable back to a source document: a bank statement line, a deposit slip, a check copy, or the original journal entry. Well-organized records make that tracing possible months or years later, which matters beyond the reconciliation itself. The IRS notes that good records "help you monitor the progress of your business, prepare your financial statements, identify sources of income, keep track of deductible expenses... [and] support items reported on your tax returns" (IRS, checked 2026-09-30), and that a record needs to be kept "as long as needed to prove the income or deductions on a tax return" – which in practice means a completed reconciliation and its supporting documents belong in the same retained file as everything else.

FAQ
Is this page different from the full bank reconciliation guide?
Yes. Bank reconciliation explained walks through the procedure, the terminology, and a single worked example from start to finish. This page is a practice set: short, self-contained questions on the same topic, grouped by the kind of discrepancy each one tests, meant for review rather than a first read of the process.
Do I need to memorize journal entries to answer questions like these?
For the questions in the adjusting-entries section, yes – knowing which side of the reconciliation an item belongs on, and whether it needs a journal entry at all, is exactly what those questions test. The debit and credit basics page covers the underlying rules if a specific entry doesn't make sense on its own.
Why do some answers say no journal entry is needed?
Because not every reconciling item is a books problem. Outstanding checks and deposits in transit are already recorded correctly in the company's own books – the bank simply hasn't caught up yet – so nothing on the books needs to change. A journal entry is only required when the books themselves are missing something or contain an error.
Could these questions appear in multiple-choice form on an exam instead?
The same underlying concepts do show up as multiple-choice questions on course tests, just phrased as a single best answer among distractors rather than an open response. Practicing the open-answer version first tends to make the multiple-choice version easier, since it forces a full explanation rather than pattern-matching to a likely option.
Where can I get a specific bank reconciliation problem checked before I submit it?
See financial accounting assignment help for how a request for a second, subject-matched review is handled – useful when a reconciliation refuses to balance and the practice questions here don't cover the specific transaction causing the mismatch.
