Property Purchased on Auction

I have purchased the residential property on auction in FY 2014-15 at bid price which is less than stamp duty value of property on the date of registration.At the same the difference between stamp duty value and purchased price is more than 50k.

Today i have received the notice from department u/s 148 saying i have escaped the income tax for the said transaction.

Do i need to pay tax on property purchased less than stamp duty value when property itself is purchased on fair market value through auction?
