Loan for Rs. 27, 43,500 has been approved to me from SBI max gain and till date a total of Rs. 24, 76437 has been disbursed to me in two installments. I have deposited Rs. 4, 50,000 in OD account. The flat for which I have borrowed this loan is still under construction and therefore I haven’t received its possession. Which loan related document I need to submit to my employer so as to attain income tax benefit?
