"Before redeeming US savings bonds, bond owners should double check to make sure they qualify for a tax-free redemption. Only bonds issued in 1990 or a later year qualify for tax-free treatment. The child must be listed as a beneficiary on the bonds, not as an owner or co-owner. The bond owner must claim an exemption for the beneficiary on his/her federal income tax return. The bond owner must have been at least 24 years old when the bonds were issued. The bond owner must have modified adjusted gross income under the income phaseouts noted above. The tax exclusion is not available to married taxpayers who file separate returns."
