Pls advise - tax exemption on stamp duty & interest

Hi,

I am salaried employee. I have purchased a resale flat in this FY. For this I have paid Rs1.67 lakhs as stamp duty & reg charges. As well my home loan interest for this flat will be aprox 1.27 lakhs & principal component will be aprox 18K (FY 2012-13).

Please advise me, what max amount tax benefit I can get from above investment? Can i claim tax exemption on both stamp duty & interest component ?

Can I get back excess TDS in case if employer has considered only interest component & not considered the stamp duty paid by me.

Kindly advise me on the issue...

Regards,
