GST paid by A will be Rs 20.16-Rs 18= Rs 2.16 only.
If B buys it at Rs 132.16, his cost will be only Rs 112, as the GST of Rs 20.16 he had paid will come back to him . Say he adds a profit of Rs 10. Then his selling price will be Rs (112+10)+ 18 % GST= 122+ 21.96=Rs 143.97. B is prohibited from taking his cost at Rs 132.16 ( as per his purchase bill) under the 'anti-profiteering' clause. The GST paid by B will be Rs 21.96-20.16=Rs 1.80 only.
As all bill details are uploaded, undue profiteering by any one can easily be found out and he may be prosecuted. more
