BANK RECONCILIATION: Timing Differences, Errors, Adjusting Entries

A bank reconciliation matches a company’s internal cash records to the bank statement. It ensures accuracy in cash reporting by identifying timing differences, unrecorded transactions, and errors.

1. What Is a Bank Reconciliation?

A bank reconciliation compares the ending balance in the company’s cash account with the ending balance shown on the bank statement.

Discrepancies are typically caused by:

  • Timing differences

  • Outstanding checks

  • Deposits in transit

  • Bank fees or interest

  • Recording errors


2. Common Timing Differences

Item

Description

Outstanding checks

Written by company, not yet cleared by bank

Deposits in transit

Recorded by company, not yet received by bank

Bank service charges

Deducted by bank, not yet recorded by company

Interest income

Added by bank, not yet recorded by company


3. Example Reconciliation Format

Bank statement balance:

  • Deposits in transit– Outstanding checks± Bank errors (if any)= Adjusted bank balance


Book (ledger) balance:

  • Interest income– Bank fees± Company errors= Adjusted book balance


The two adjusted balances must equal.


4. Adjusting Entries in Company Books

After completing the reconciliation, adjusting entries are made for any unrecorded transactions found on the bank statement.


Examples:

  • Bank fee deduction:

    • debit Bank Fees Expense

    • credit Cash

  • Interest income:

    • debit Cash

    • credit Interest Income

  • NSF (bounced) check:

    • debit Accounts Receivable

    • credit Cash


5. Errors and Corrections

If the company discovers an internal error (e.g., recorded $650 instead of $560), it must correct it:

  • debit or credit Cash (to adjust difference)

  • offsetting entry based on original transaction

Bank errors should be reported to the bank but not adjusted in the company’s books unless confirmed.


6. Frequency and Best Practices

  • Reconciliations are typically done monthly, but high-volume companies may reconcile weekly or daily.

  • Maintain supporting documentation for all adjustments.

  • Use a template for consistency and audit readiness.

  • Review by a supervisor ensures internal control.


7. Financial Reporting Impact

Bank reconciliations do not appear in the financial statements but support the accuracy of the cash balance on the balance sheet.


Unreconciled differences could:

  • Indicate fraud or theft

  • Lead to misstated cash balances

  • Trigger audit findings


Key take-aways

  • Bank reconciliations align company records with actual bank balances.

  • They identify timing differences, errors, and unrecorded transactions.

  • Adjusting entries are made to update the company’s books.

  • Routine reconciliations strengthen financial accuracy and internal control.
