Section 56(2)x and section 50c

Sir, I can only co-relate by showing the cheque that i have paid to his account. Actually the scenario is He had an agreement with the builder in 2011 for 22 lacs and at that time stamp duty value is also 22 lacs, but he has not registered the deed, than i purchased from him in 30 lacs last month and now stamp duty value is also 30 lacs, but in registered deed builder have only shown 22 lacs as this is the money he actually received. remaining 8 lacs i paid to the original owner through cheque before registered deed. 

As the value of the property is exactly 30 lakhs, Sub-registrar will sent information to ITD. Based on that you are bound to receive notice from department. To justify your claim of payment of Rs. 8 lakhs to first allottee you should collect all the previous information about the allotment and its cancellation, including the declaration of the 8 lakhs premium received by the first allottee in his ITR (and paid taxes over it, if liable). Otherwise you will have to pay the remaining part with interest & penalty.

Sir, I have all the previous information regarding the allotment and cancellation of previous owner and also regarding the transfer from his name to mine. But i do not get his ITR return. Is showing the banking cheque payment of total 30 lacs to his name is not sufficient to justify our claim

Department is interested in revenue, and here you have to save yourself. So, getting his ITR and liable tax payment, if any; will only help you.

Thank you sir. Just one last thing in registered deed company have mentioned that "there is agreement between myself and the company in 2011 for which we have paid by cheque". however this agreement is between the previous owner and the company but now they have transferred that agreement to my name and have mentioned the same in sale deed. Can we take benefit of this language and use stamp duty value of 2011.

No.

For that you should have paid advance amount by cheque/DD/
