No,nothing along the lines of a ban is either in the making nor has it occured yet. I think you're confusing regulatory action and banning something, as India is getting stricter and stricter with the regulations that they're imposing on bitcoin. For more info, I'd check here - https://techcrunch.com/2018/02/03/psa-no-india-hasnt-banned-bitcoin-but-its-still-talking-tough-on-crypto/
It seems this information is helpful
But if its true India bans bitcoin/crypto and about the tax for bitcoin/crypto holders to keep save their bitcoin/crypto, it seems the Indian government is trying earn benefit from bitcoin holders.
Even Ive never heard if the Chinese government which had banned ICOs is taxing the bitcoin/crypto holders.
