IRS Form 1099-INT – In today’s financial landscape, managing your taxes effectively requires a clear understanding of various IRS forms. One such essential document is IRS Form 1099-INT, which reports interest income. Whether you’re a taxpayer receiving interest from savings accounts, bonds, or other investments, or a payer responsible for issuing the form, knowing the ins and outs of Form 1099-INT can help ensure compliance and avoid penalties. This guide breaks down everything you need to know about IRS Form 1099-INT – Interest Income (Info Copy Only), including its purpose, key components, and how it impacts your tax return.
What Is IRS Form 1099-INT?
IRS Form 1099-INT is an information return used to report interest income paid to individuals or entities during the calendar year. It’s part of the broader 1099 series of forms, which the IRS uses to track various types of income beyond wages. Specifically, this form details taxable and tax-exempt interest payments, helping the IRS match reported income with what taxpayers declare on their returns.
The “Info Copy Only” version, available for download from the IRS website (e.g., via the provided link: https://www.irs.gov/pub/irs-pdf/f1099int.pdf), is intended for reference purposes. It’s not meant for actual filing with the IRS, as printed copies from the site may not be scannable. Official filable copies must be obtained directly from the IRS or through approved software. Payers, such as banks, credit unions, or brokerage firms, issue this form to recipients who earned at least $10 in reportable interest.
Interest income can come from sources like:
- Savings and checking accounts
- Certificates of deposit (CDs)
- U.S. Treasury obligations
- Corporate bonds
- Tax-exempt municipal bonds
Even if the interest is tax-exempt at the federal level, it must still be reported, as it may affect state taxes or alternative minimum tax (AMT) calculations.
Who Needs to File or Receive Form 1099-INT?
Payers: Who Files the Form?
Financial institutions and other payers must file Form 1099-INT with the IRS for each recipient if:
- They paid at least $10 in interest reportable in boxes 1, 3, or 8.
- They withheld and paid foreign tax on interest.
- They withheld federal income tax under backup withholding rules, regardless of the amount.
Exceptions include payments to corporations (with some caveats, like certain bond credits), exempt organizations, or foreign persons (reported on Form 1042-S instead). Nominees or middlemen, such as those handling payments for others, must also file if the interest belongs to another party.
Recipients: Who Gets the Form?
As a taxpayer, you’ll receive Copy B of Form 1099-INT by January 31 if you earned qualifying interest. This includes individuals, sole proprietors, and certain trusts. If you don’t receive it but know you earned reportable interest, you’re still required to report it on your tax return—contact the payer if needed.

How to Report Form 1099-INT on Your Tax Return?
Recipients must include the information from Form 1099-INT on their federal tax return, typically on Schedule B (Form 1040) if total interest exceeds $1,500. Taxable interest (Boxes 1 and 3) is reported as ordinary income. Tax-exempt interest (Box 8) is entered on Form 1040 but not taxed federally, though it may impact Social Security benefits or state taxes.
For adjustments like bond premiums (Boxes 11-13) or market discounts (Box 10), consult the instructions for Schedule B or Form 6251 for AMT. If backup withholding occurred (Box 4), credit it against your tax liability.
Filing Deadlines and Electronic Requirements
Payers must furnish Copy B to recipients by February 2, 2026 (for 2025 tax year interest). File with the IRS by March 2, 2026 (paper) or March 31, 2026 (electronic). Electronic filing is mandatory if submitting 10 or more information returns. Extensions can be requested via Form 8809.
Penalties for Non-Compliance
Failing to file or furnish accurate Forms 1099-INT can result in penalties ranging from $60 to $340 per return, depending on timeliness and intent.
