Welcome the QuickBooks community. I’ll be happy to assist with your expenses report. With QuickBooks Online, you can generate and customize reports to keep an eye on your business finances. That being said, adding a GST column to the expenses report is not an integrated feature of the system. If you wish, you can add a Tax Code and Tax Amount columns to the Transaction List by Supplier report. To do so, follow these steps:
Select Reports from the left menu
Scroll down to the Expenses and suppliers section
Select Transaction List by Supplier
Select the little gear icon next to the Email, Print, and Export icons
Select Show More
Check the boxes next to Tax Code and Tax Amount
Select the little gear icon again
The report will now show a separate column for the tax codes and amounts corresponding to each transaction.
