THOSE looking to save tax should take note of the latest buzz in the debt markets. Power Finance Corporation ( PFC ) and Housing Urban Development Corporation (Hudco) have launched bonds that will help you save more tax than your regular infrastructure bonds. Soon, IRFC and NHAI are likely to follow suit with similar bonds. KP Jeewan, general manager, debt markets, Karvy Stock Broking, says: "The coupon in these bonds are completely tax-free and those in the highest tax bracket can expect an effective yield of 10.75 per cent, compared to the 9.5 per cent a 10-year public sector bond would offer." The PFC and Hudco offerings are of 10- and 15-year tenures, with coupon rates of 7.5 and 7.75 per cent, respectively. Unlike other regular tax-free infra bonds, the tax benefits in these bonds are not capped at ` 20,000. Even besides these tax free bonds, those in the highest tax bracket have had plenty of opportunities to invest in tax saving infrastructure bonds under 80 CCF i
