CDs are not sold at a discount, unlike other short-term money market instruments. CDs pay interest on the money deposited usually on an annual basis. For CDs with a maturity of less than one year, interest is paid at maturity, and taxes are due on the earnings each year. However, for investors who don’t need to receive interest payments each year, a zero-coupon CD provides a return by being sold for their face value at maturity, which is higher than the initial investment.
