Is there any way to track GST and QST in different G/Ls?

Hey info718,

The sales tax centre in QuickBooks Online includes some powerful tracking to make filing taxes easy. By default, the system tracks both taxes in a single general ledger account. This is necessary if you want to take full advantage of the sales tax features, but I can show you how to see the amounts separately. 

While the liabilities will be represented in a single account, you can easily see them broken down separately by running a simple report:

1. Head to your Reports tab on the left-hand side of your QuickBooks Online. 
2. Scroll down to the Sales Tax section and select you GST/HST - QST Detail Report.

This is an incredibly useful report, as it'll accurately give you a breakdown of GST Payable, GST Receivable, QST Payable, and QST Receivable on their respective lines. Alternatively, the GST/HST - QST Summary report can be used to quickly see the totals. 

Let me know if there's anything else I can help with.
