A flat purchased in 1999 was registered at 3.9lakhs only. For capital gains tax calculation, what shall be the value of the property? Shall I take only the registered value or sum of registered value of the property and the registration duties paid? What about the interior which was done? How the value shall be computed and what evidence do I need to give to tax authorities? Is Capital gains tax calculated by the tax payer and declared or will there be a scrutiny? I want to do a clear dealing so that I do not give chance for corruption.
