Hey @Nishant_Sinha,
Presumptive taxation scheme was introduced for those businesses/professionals who are unable to maintain books of accounts and thus can report a fixed percentage of their turnover/revenue as profits and pay taxes on the same. However, in case of trading income, where all transactions are digital and the books can be easily maintained, it is recommended to report as normal business income. Moreover, if you opt for the presumptive taxation scheme, 6% of your profits or actual profits, whichever is higher, need to be reported.
