80c benifit from principal payment in sbi maxgain

Hello,

I have to give the investment proofs for FY 2014-15 to my company. My 80C slab is not filled upto the limit. I am thinking to pay some amount as principal in my SBI maxgain & show it in 80C to take the benifit for tax exemption.

I want to know whether I can take the tax exemption on th eamount paid as principal in my SBI maxgain homeloan account.

Thanks.
