If a flat is sold for 38 lakhs but sale agreement is done for 20 lakhs and 20 lakhs sale proceeds is received through bank account
and the remaining amount of 18 lakhs is received in cash..
would there be any problem in this case from IT dept if the capital gains is calculated considering 20 lakhs only as Sale consideration?
