When I do the BAS report my 1A is showing a negative number. As far as I can figure out this is because G1 is only including the normal GST inclusive sales and not the GST free export sales, and my G2 exports (tax code EXP) exceeded my normal GST inclusive sales this quarter.
I have gone to settings and under 'tax settings and codes', the GST coded sales have under the 'report label' 1A, G1, G1, and the EXP have 1A, G1, G1, G2,G2. So these look right. So am am a bit lost as to what the problem could be.
