I have trading in commodity by script in alumini buy 137.55 and sale rate 138.65 total profit is rs.2, 200.

Brokerage is 27.5+27.5+27.7=rs 82.7
Cgst is 12.97, sgst 12.97, clearing changes 19.33, transaction charges 14.36, ctt 28, sebi 0.55

Total brokerage plus others= 170.88

Net profit is= 2, 029 is correct

But our report and added net profit is 2001.

Gst applicable only for brokerage, clearing changes, and transaction charges only
But gst not applicable to commodity transaction tax.
