The 1099-INT form (Interest Income) is an IRS tax form used to report interest income paid to an individual or entity during the tax year. Banks and other payers use this form to inform both the taxpayer and the IRS about interest earnings.
Interest income can come from multiple sources, including:

If you earned taxable interest, it must be reported using the interest income tax form, even if you did not receive a physical copy.

A form 1099 INT is typically issued by:
