Tax liability

Is it tax free bond if yes then exempt

Is intt.income on IDFC INFRASTRUCTURE BOND TAXABLE?

IDFC bonds are two types earlier they are not tax free bond later they gives tax saving bonds as I don't know if it tax free or not
if it is tax free then see the limit of that amount that will be exempted
again if it is fully tax free then fully exempted
again if it is not tax free then the interest will be treated as income and you will show it in others source of income
