If tax deduction has been made at source before remittance to you, the same will not be taxed in India provided you produce proof of deduction at source. However, if you have received the full amount of winning, you will have to pay tax in India for the said amount shouwing income from lottery winning.
Thank you so much for your clarification sir. So as I understand even if I play in the casino outside India I must pay an income tax unless they do it themselves. But this is about regular casio, right? And if I buy a lottery ticket on this website and pay with, let's say, Bitcoin? Or even not Bitcoin, but Dogecoin for example. Will the same legal and taxation rules apply?
If you want to be more careful in the future then I would suggest not using fiat money with your online casino play. Instead, you should consider playing on a Bitcoin Casino where your money will be more secure, you will get better odds and faster service. Stay safe out there.
