You can fix this by undoing the reconciliations that used the wrong year, then redoing them with the correct dates. QuickBooks Desktop carries each reconciliation's ending balance forward as the next one's beginning balance, so you'll need to undo them in order, starting with the most recent one, until you get back to the reconciliation where the wrong year was entered.
Why this keeps happening
Once a reconciliation is saved with the wrong statement date, QuickBooks Desktop uses that date as the starting point for the next reconciliation. That's why the wrong year has carried forward every month since it was first entered instead of correcting itself.
Step 1: Undo the affected reconciliations
- Back up the company file before you start. This protects the data in case you need to start over.
- Go to the Banking menu and select Reconcile.
- Select Undo Last Reconciliation. The beginning balance reverts to the one from the reconciliation before it, and all cleared transactions on that reconciliation become uncleared.
- Repeat this for each reconciliation, working backward month by month, until you reach the one where the wrong year was first entered.
Step 2: Redo each reconciliation with the correct date
- Go to the Banking menu and select Reconcile.
- Choose the account, then enter the correct Statement Date from the bank statement.
- Confirm the Beginning Balance matches the statement.
- Enter the Ending Balance, Service Charge, and Interest Earned from the statement.
- Select Continue, match the transactions, and select Reconcile now once the difference shows $0.00.
A faster option for catching up several months at once
If there are many months to redo, they don't have to be reconciled one statement at a time. QuickBooks Desktop lets you catch up a whole stretch of months in one pass, working one fiscal year at a time:
- Pick the ending statement for the last month in the year being caught up.
- Add together the service charges from every statement in that stretch and enter the total in Service Charge. Do the same for Interest Earned.
- Select Hide transactions after the statement's end date, then check off every transaction that appears across all the statements being covered.
- Once the difference shows $0.00, select Reconcile Now.
- Repeat for the next year if more than one year needs to be caught up.
Since this method touches more than one reporting period, it's worth reviewing the approach with an accountant before starting.
