Overview

Form 1099-INT is the IRS information return used by banks, credit unions, brokerage firms, financial institutions, and other payers to report interest income paid to recipients during the tax year. This may include taxable interest, tax-exempt interest, U.S. savings bond and Treasury obligation interest, federal income tax withheld, foreign tax paid, bond premium, and other interest-related amounts. This form must be filed with the IRS and a copy must be furnished to the corresponding recipient.

The TaxBandits API enables you to automate 1099-INT filing directly from your existing systems. If you already have recipient data and interest income details in your system, use the API endpoints to create and transmit 1099-INT forms directly.
