Form 1099-INT reports interest income you earned from banks, savings accounts, CDs, and bonds. You'll receive one if you earned $10 or more in interest. The interest is taxable as ordinary income in the year you receive it. Report it on Schedule B if your total interest income exceeds $1,500. High-yield savings accounts and money market accounts generate 1099-INT income; so do Treasury bonds (though Treasury interest is exempt from state income tax).
