Dear Sir,
Hope you are doing well !
There is no specific provision in the Income-tax Act, 1961 about the taxability of cryptocurrencies. However, keeping in view the general provisions of the Income-tax Act, cryptocurrencies could be deemed as capital assets if they are held as an investment by the taxpayer.
Therefore, any gain arising from it should be taxable as capital gains. If a cryptocurrency is held for more than 36 months from the date of purchase, it will be considered as long-term capital asset. And if held for less than 36 months, it will termed as a short-term capital asset. For capital gain, you will have to file ITR 2.
On the contrary, if transactions in bitcoins are substantial and frequent, it could be held that the taxpayer is trading in cryptocurrencies and the resultant profits would be taxable as business income. In such case, you will have to file ITR 3 or ITR 4 (presumption taxation scheme).
Thanks & Regards,
