Income Tax exemption question

Hi,

I have heard that the service tax which we pay during registration of new House property is exempted from Income Tax. However, I'm not sure under which section one can show that in his/her ITR filing form. Can anyone please tell me whether the service tax on house registration is indeed exempted from tax and if yes, how to claim the exemption?

Another question is regarding PF withdrawal. When one withdraws PF while moving from one Organization to another, is the entire amount withdrawn liable for tax or is it just the Interest portion or Employee Contribution portion of it?

Thanks in advance,

Aditya
