Interest is reported to you and the IRS from your bank on Form 1099-INT. If your interest is paid in a brokerage account, it may be reported on a consolidated Form 1099, which can include things like dividend income and profits from stock sales. With your tax return, interest income is reported on Schedule D. And the IRS requires you to report all of the interest income you receive during the year, even if you didn't receive a Form 1099 documenting it.
