No idea about tax laws in India, and frankly, I'm not an expert about the tax laws in the US, but here, there is a "gift tax" that applies whenever property is transferred between individuals as a gift. There is an annual exclusion which I think is actually 11,000, very close to the cash value of your 500,000 rupees. So in the US, there would be no taxes owed on a gift of 500,000R.
But if there's a similar law in India, and the exclusion amout is less (and I'd imagine it is, as 500,000R is more than ten times the average annual income in India), then you're asking people to help you break the law in this
thread, plain and simple. If anybody can confirm all this for me, then I'm going to close this topic.
