Do I need to report small amounts of interest?
Yes. All taxable interest income should be included, no matter how little the amount is.
Your bank should send you a Form 1099-INT. However, some banks might not send a Form 1099-INT for interest of less than $10. If you earned interest, but didn't receive a Form 1099-INT, you should contact your bank or check your bank statement to find out how much interest you earned.
