I Bonds are U.S. Treasury securities backed by the U.S. Government. I Bonds even protect you from the effects of deflation. I Bonds earn interest for up to 30 years. Earnings are exempt from state and local income taxes. Federal income taxes can be deferred for up to thirty years, or until redemption or other taxable disposition, whichever comes first.
Bonds fit all budgets.
