What Is a 1099-INT Form and How Do I Report Interest Income?

When tax season approaches, many people think about wages, contractor payments, or dividends, but interest income is often forgotten. If your business pays or earns interest, Form 1099-INT is a key document that ensures you stay compliant with IRS reporting requirements.

Key takeaway: Form 1099-INT reports interest income paid to individuals or businesses, and filing it accurately helps prevent IRS penalties and ensures proper tax reporting.

What Is Form 1099-INT?

Form 1099-INT is used to report interest income paid to an individual, business, or other entity. This includes interest from savings accounts, loans, bonds, and other financial instruments.

If your business or financial institution pays $10 or more in interest during the year, you must issue a 1099-INT to the recipient and file a copy with the IRS.

Common examples of payers include:

• Banks and credit unions
• Real estate or private lenders
• Businesses paying interest on late invoices or loans
• Brokerage firms paying bond interest

The IRS uses these forms to match reported income with taxpayers’ returns, ensuring that all interest income is properly declared.

When Do You Need to File a 1099-INT?

You must file Form 1099-INT if your business or institution paid $10 or more in interest to any individual or entity during the calendar year.

You’ll also need to file if you:

• Withheld and paid any federal income tax under backup withholding rules
• Paid tax-exempt interest
• Paid foreign tax on interest income

Filing deadlines:

• Recipient copies due: January 31
• IRS electronic filing deadline: March 31

You can find official filing rules and thresholds for the 1099-INT on the IRS website, which offers detailed instructions for every box and situation.

What Information Is Reported on the 1099-INT Form?

The 1099-INT form has several boxes, each serving a different purpose. Here’s a breakdown:

Filing the correct information ensures the IRS and your recipients can accurately report and reconcile their income.

Who Files Form 1099-INT?

You’ll need to file Form 1099-INT if you are:

• A bank, lender, or financial institution paying interest on accounts or loans
• A small business that loaned money and earned or paid interest
• A corporation or partnership that pays interest to investors or other parties

Even if you only paid interest once, or to a single recipient, the IRS still requires you to report it if it exceeds $10.

Common Filing Mistakes to Avoid

Filing 1099-INT forms may seem straightforward, but small mistakes can create big problems. Here are common errors to watch for:

• Incorrect TINs (Taxpayer Identification Numbers)
• Reporting interest on a 1099-MISC instead of 1099-INT
• Failing to report tax-exempt interest in Box 8
