My father had a land that he acquired from his own source of income i.e the property belonged exclusively to him. We are three brothers and mother is surviving and styaing with us in turns as per her wish. My father has expired since and because none of us is interested in that property, we decided to dispose the land with mom's consent. Now mamma told that the total momey should be divided into three parts and she needs nothing. We got eight lakhs each from that property. The land was acquired long back probably in the 1970s. My question is whether this additional money is to be treated as income and taxed? If so, how to show and how much tax is to be paid?
