Comment on Taxation for Traders - Introduction
Venkat,
As an NRI you are not allowed to directly trade on equity and commodity derivatives. You need to get RBI approvals and do all your trading through a custodial account, which would make sense only if the account size is big.
You would still have to pay taxes as what is applicable in India before repatriating. You can see the tax rates in this blog.
Even if trading is done through a friend’s account, taxes will be still applicable, but the only good thing with this is that if the friend is a resident Indian he won’t require a custodian or any restrictions in terms of what he can trade.
Cheers,
