GST reporting codes

The BAS report layout is specific about how and where different amounts should be reported, about the fields that are added together and about linking the GST codes to the particular reporting codes. The GST reporting codes refer to a field number on the tax report for the report layout. The codes are linked by associating a GST code to a particular reporting code on the Report setup FastTab on the GST codes page.

Based on a quarterly BAS format, the following reporting codes must be set up. These reporting codes are associated with the field that appears on the BAS report.
