Hi, I bought a land (plot) in March 2007 for Rs4,50,000. The buyer insisted on cash payment and the registration was also done as per circle rates (Rs40,000) which was very less. I paid by white money (withdrawn from bank) to him all the Rs4,50,000. Now, I have sold this for Rs8,80,000, and the registration is also done as per current circle rate of Rs54,000/. Now, I have few questions. 1) My actual net income is 8,80,000 - 4,50,000, which is Rs4,30,000/- I am ready to pay 20% tax for this income. Now, how do I prove that my purchase cost was Rs4,50,000? Since the registration papers are not showing the actual money that I spent, what is the alternate option to show to income tax department about the actual? 2) I have deposited my current income of Rs8,80,000/- into three banks. I want to buy another plot in a different place. The other plot owner is also insisting on paying everything by cash. Again, the registration is also based on circle rates which is very low. Is there a way to make it legal with everything as white? Regards, Sriram.
