How to fill out a 1099-INT form: A guide to interest income reporting

The following suggestions are for informational purposes only. For current requirements, see the IRS instructions for Form 1099-INT.

Interest payments can seem straightforward—until it is time to decide whether an information return is required, which box applies, and how to deliver the right copies on time. Form 1099-INT is how many financial institutions, businesses, government agencies, nonprofits, and nominees report qualifying interest payments to recipients and the IRS.

If you received a Form 1099-INT, you usually do not fill it out yourself. You use it to help report interest on your tax return. If you made reportable interest payments in the course of a trade or business, this guide walks through the payer’s filing process and the most important boxes to review.

What is Form 1099-INT?

Form 1099-INT, Interest Income, reports certain interest payments. It may show taxable interest, U.S. savings bond and Treasury interest, tax-exempt interest, federal income tax withheld, foreign tax paid, and other information. The payer sends a recipient copy and files the required information return with the IRS.

Who needs to file Form 1099-INT?

Generally, file Form 1099-INT for each person to whom you paid at least $10 in reportable interest shown in Box 1, Box 3, or Box 8; for whom you withheld and paid foreign tax on interest; or from whom you withheld and did not refund federal income tax under the backup-withholding rules. Interest paid in the course of your trade or business may also be reportable in certain circumstances under the specific instructions.

Reporting applies to interest paid in the course of a trade or business, along with certain payments by government agencies, nonprofit activities, and nominees or middlemen. Exceptions apply, including certain exempt recipients and excluded interest, so verify the recipient and payment before creating a form.

What you need before filling out Form 1099-INT

  • Payer name, address, telephone number, and TIN
  • Recipient name, address, and taxpayer identification number
  • Interest-payment records classified by taxable, Treasury, tax-exempt, and other categories
  • Backup withholding and foreign-tax records, if applicable
  • State reporting information, if your filing requires it

Pro Tip

Preparing Form 1099-INT is just one part of handling tax paperwork. Good tax form management also means keeping recipient information accurate, tracking filing deadlines, and storing completed forms securely. An organized process makes it easier to manage multiple tax forms and avoid last-minute errors.

How to fill out Form 1099-INT

1. Complete payer and recipient information

Enter the payer’s legal name, address, telephone number, and TIN in the payer fields. Enter the recipient’s legal name, address, and TIN in the recipient fields. Use validated W-9 information when appropriate and resolve a missing or incorrect TIN before filing whenever possible.

2. Report interest in the correct box

Box 1 generally reports taxable interest not included in box 3. Box 3 is for interest on U.S. savings bonds and Treasury obligations. Box 8 reports tax-exempt interest. Box 9 reports specified private activity bond interest, which is also included in the Box 8 total. The correct box affects the recipient’s tax reporting, so avoid combining distinct interest types just because they were paid to the same recipient.

3. Complete withholding and tax boxes when they apply

Use the applicable boxes for early withdrawal penalties, federal income tax withheld, foreign tax paid, and foreign country or U.S. possession information. Backup withholding is reportable even if the payment amount would otherwise be below the normal threshold. Review the specific instructions before entering a withholding amount.

4. Review state information and copies

Complete the state boxes when state reporting applies. Then prepare the required recipient, IRS, and payer copies using the current filing method and form version. Do not mail a printed Copy A downloaded from the IRS website. For paper filing, use the official scannable red Copy A and include Form 1096; otherwise, file electronically through an approved IRS method.

When are Form 1099-INT copies due?

The General Instructions for Certain Information Returns set the filing and furnishing deadlines. Form 1099-INT recipient statements are generally due by January 31. IRS filings are generally due by February 28 when filed on paper or March 31 when filed electronically, subject to weekend and holiday adjustments. Filers required to submit 10 or more information returns in aggregate generally must file electronically, unless the IRS grants a waiver.

What recipients should do with Form 1099-INT

Recipients should keep Form 1099-INT with their tax records and use it to prepare their tax returns. Taxable interest is generally reported on Form 1040, while tax-exempt interest is also reported even though it is not generally subject to federal income tax.Schedule B is generally required when taxable interest or ordinary dividends exceed $1,500, as well as in certain other situations. Taxpayers must report taxable and tax-exempt interest even if they did not receive Form 1099-INT.

Common Form 1099-INT mistakes to avoid

Small classification and filing errors can create incorrect recipient statements, backup-withholding issues, or time-consuming corrections. Review the payment type, recipient information, and filing rules before preparing Form 1099-INT.

  • Filing without checking the reporting rules: Do not issue a form automatically for every interest payment. Confirm the applicable threshold, whether the payment was made in the course of a trade or business, and whether an exception applies.
  • Using the wrong box: Keep taxable interest, Treasury interest, and tax-exempt interest separate. For example, Treasury interest generally belongs in Box 3, while tax-exempt interest belongs in Box 8, not Box 1.
  • Relying on unverified recipient information: Request a completed Form W-9 when appropriate and compare the recipient’s name and TIN with your records before filing.
  • Overlooking withholding requirements: Backup withholding can create a filing requirement even when the interest payment is below the usual reporting threshold.
  • Choosing the wrong information return: Form 1099-INT reports interest. Review whether the payment instead belongs on Form 1099-DIV, Form 1099-OID, Form 1099-NEC, or another return.
  • Waiting until the deadline: Build in time to furnish recipient statements, file with the IRS, address rejected electronic filings, and correct any errors you find.
