You can very well do this. All you need to do is to submit all the proofs to a tax consultant and recalculate your tax. He would charge you a nominal amount(Rs.300 to Rs.500). Also you need to fill in refund form. Your tax form will be filed with ITO along with the refund form, and this can also be done by the tax consultant. You will be receiving the tax refund in a couple of months
