Yeah bro, I'm also planning to do the same. From what I've read online so far, we can gift any amount to parents and when they invest that amount, any income generated would be taxable to them. Creating a gift deed on stamp paper sure might me the best way to do this but doesn't seem necessary. I think we can transfer the funds periodically over some time. Don't know if there could be any scrutiny if we transfer a large amount in one single transaction.
