How will you determine the taxable turnover under the CST Act?

1st step:- Add particular sales to calculate gross sale.

2nd step:- Deduct tax free sale and the sale which does not included in definiton of goods and exempted sale. This will result in turnover including cst

3 step:- calculate cst from interstate sale and deduct from turnover including cst (if the dealer is registered dealer and having form C then the cst rate is 2 % and local sales tax rate which ever is less.)
