Hi,My father has sold his agriculture land which received from his father and this land area under Municipal Corporation, buyer has paid the stamp duty/ registration fee and land value is 8 lakhs. Does this amount taxable or not to my father? My father has a farmer and he is planning to build a house with this amount in another land. Please give your suggestion on income tax applicable or not ?
