We can explore the possible reasons why unreconciled transactions appear in the following month, 4wael.
Firstly, if a deposit from the previous month was entered into QuickBooks but has not yet cleared with the bank, it will remain uncleared. As a result, it will show up in future reconciliations until it is matched with a bank statement.
Secondly, if a deposit from October 2025 is added or edited after reconciliation, QuickBooks will mark it as unreconciled, so it will show up in the next reconciliation.
To address this issue, review the previous month's reconciliation report to identify missing or unmatched transactions. Ensure all transactions for that month are entered and matched in QBO, and refer to the bank statement for accuracy.
Unreconciled transactions in QuickBooks may result from date errors, edits, or duplicates. If they belong to the previous month, manually reconcile them in the register.
If a transaction isn’t on the current bank statement, leave it unchecked during reconciliation. It will carry over to the next month’s reconciliation until it clears the bank. Once it appears on the bank statement, you can reconcile it in QuickBooks.
