For the Square to QBO integration through APP Transactions, is it possible to use the QBO tax codes rather then the Sales tax coming over as a line item?

Hey there, jcollins9260.

I appreciate you reaching out to the Community for support. I'd be happy to provide some information about square to QBO integration.

As long as the sales tax codes are completely identical between Square and QBO, the sales taxes will be automatically mapped to the correct account.
To verify, you can compare the Sales Tax setup by logging into both the Square website and your QuickBooks Online account. You can also follow these steps on how to check the app settings in QBO:

1. Go to the "Transactions" menu and proceed to the "App Transactions" tab.
2. Click "App settings" in the right-hand corner.

You can read more details about Square and QBO integration in this article: Connect Your Square Account To QuickBooks Online.
