I'm having trouble including GST in a journal entry. I have selected GST on purchases, but when doing the bank reconciliation the amount is only showing the net figure.

Hi cdwilliams2785,

Did you assigned a GST code on each line of the Journal Entry? If so, try to edit the journal and assign GST code on Line 1 only.  Furthermore, since you set the journal entry to Inclusive of tax and the accounts affected is a GST Liability this will still show the total amount of the transaction in the bank reconciliation. 

We'd recommend viewing the Transaction journal of the journal entry for you to check the accounts affected. Here's how:

1. Locate and open the Journal entry.
2. Click on More.
3. Click Transaction journal.
