Supplier not on-charging GST Hi There, A contractor has invoice our company for hours worked for the month and included two line items, 1) telephone expenses, 2) Employment Law course fees (required for the role). The contractor is registered for GST but has not included GST on the two expense claims because they have already paid and claimed the GST prior. Is this correct? Should they still be including the GST or not?
