Missing an entire year of reconciled transactions

There are a few reasons why this could happen, Mothersmucker.

For QuickBooks Online:

• Your Accountant may have used the Undo Reconcile tool. This can change the reconciliation status of the transactions removing the corresponding reconciliation report.
• The reconciled account was merged with another account.
• You exported reconciled transactions from other version to QBO

Let's try to check the causes of the missing transactions by running your Audit log and the reconciliation report. Also, refer to this article on how to view details for missing reconciled transactions.

In QuickBooks Desktop, let's run the reconciliation report and review the audit trail as well. If there are no issues, you can verify if the Hide transactions after statement's end date box at the top of the reconciliation screen checked. You'll have to remove the check mark to view the reconciled transactions.

QuickBooks Self-Employed doesn't support the reconciliation process. It could be one of the reasons why you can't see the reconciled transactions if you converted other QuickBooks product to QBSE.

You can always reach out to me if you have further concerns about reconciling. I'd be around to help!

The Hide transactions after the statement's end date box is only found in QuickBooks Desktop, Mothersmucker.

I'll walk you through on how to look for this option. Here's how:

1. Go to Banking and click Reconcile.
2. Enter the necessary information and click Continue.

The Hide transactions after the statement's end date box is at the top right corner of the Reconcile screen. If this option is checked, kindly remove the check mark to view the missing reconciled transactions.

Also, you can run the reconciliation report and review the audit trail as well and check if there are missing transactions.

If you're using QuickBooks Online, there are a few reasons as to why the reconciled transactions are missing. These reasons are mentioned by my colleague @Catherine_B above. You can view the changes of the reconciliation reports in the Audit Log. This feature displays the history of the changes made to your reconciliation reports as well as the user information for each change.

Here's how to view the Audit Log: 

1. Go to the Gear icon and click Audit Log.
2. Click the Filter button.
3. Under Events, click Reconciliations.
4. Click Apply.

Also, you can check the changes made to the individual reconciled transactions. To do this, please refer to the steps in running the Audit Log and locate the transactions to open it. Select More and select Audit history.

Once done, the reconcile changes are showed in the CLR column.
