How to edit a transaction that is included in a BAS return?

You have to unfile the BAS return of that particular period (after deleting the payment/claim if you have recorded any) to edit a transaction. Here’s how:

• Go to the Reports module on the left sidebar.
• In the Taxes section, select BAS.
• Select the return you wish to unfile.
• Click Mark as Unfiled.
• Click OK to confirm.

Once you unfile the BAS return, you can go ahead and edit the transaction of your choice.
