Can you change the date of a reconciled account once you have reconciled it? I mistakenly entered the incorrect year of the month I was reconciling

Greetings, @contact159.

If you need assistance altering the reconciliation monthly/year-end date in QuickBooks Online, you've come to the correct place.

The procedures below are to change the reconciliation ending date if you haven't finished the reconciliation.

Here's how:

1. Click Accounting in the left panel and select the Reconcile tab.
2. Choose the bank account from the Account drop-down list.
3. Tap the Resume reconciling button.
4. From the upper right-hand corner, click the Edit Info button.
5. Change the reconciliation year date from there.
6. Hit Save.

Moreover, you will need an easy way to undo the reconciliation and change the year date if you have already concluded the process, only QuickBooks Online Accountant has the Undo feature. I would advise bringing your accountant in to undo the whole reconciliation period.

Here's how:

1. Click the Gear icon in the upper right corner, and select Manage Users.
2. Go to the Accounting Firms tab, enter the accountant's email, and click the Invite button.
3. Hit Save.
4. Once invited, have your accountant undo the whole reconciliation.
