G10 in GST Calculation workshet

An amount appears in the G10 section even if nothing has been deemed capital expemditure
Any advice would be appreciated
I do not use the purchase function for this client …only the cash bbo function is used

Have a look at the Tax Audit report for the same period as is your BAS. Generally GST assigned to asset account will be classified as a capital purchase thus will show under G10 section.
