Is interest from a U.S. Savings Bond tax exempt from Connecticut Interest Income?

[KrisD · Accepted solution]

Yes.

"Interest income from directly owned obligations of the United States Government is exempt. Some examples include interest on bonds, notes, bills, certificates and savings bonds offered by the U.S. Treasury. Interest from bonds or other instruments not issued by the federal government, but guaranteed by the federal government, is taxable in Connecticut."
