Hi CHKBooks,
Thanks for posting your concern in the forum.
I understand the need to make sure everything is correct when lodging your BAS report. In my understanding, you can also run the GST Return report instead of comparing the BAS information to the current ledger information. It's also likely that there is a ledger account in your file that was not mapped correctly. You can click the setting buttons and click the Check field setup to see if all the necessary accounts are linked to the right fields. I recommend reading through this article, Get Ready to Lodge Activity Statements. This will give you further information regarding the online BAS.
Let us know if you require any further assistance.
Thanks,
Genreve
