I have done my recent books and reconciled my bank. I now have to add my last years books for SARS. Do I have to unreconcile my bank completely?

It's good to have you here in the Community, info-thedancewar.

Yes, you'll need to undo your reconciliation and then add the last year's books for SARS. This is to avoid messing up your data.

The QuickBooks Online Accountant (QBOA) gives you the ability to Undo reconciliations without manually editing individual transactions from within the register.

However, if you don't have an account version of QuickBooks, I'd recommend inviting an accountant to your company and letting them do the process. 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 reconciled transactions.

Otherwise, you'll need to undo them one at a time. You can use this article for reference: Undo and remove transactions from reconciliations in QuickBooks Online. On the same link, you'll find a write-up that provides steps on how to adjust as well as fix beginning balances.

Should you have any other concerns, please let me know. I'd be more than willing to provide additional assistance. Have a good one.
