If you've received interest income from a bank account, savings bond, or other investment, you may receive a Form 1099-INT—a tax document that reports that income to you and the IRS. Understanding what this form is, who gets one, and what to do with it is important for filing accurate taxes.
A 1099-INT is an IRS tax form issued by banks, brokers, and other financial institutions to report interest income paid to you during the year. "INT" stands for interest. The form documents how much interest you earned—information both you and the IRS receive.
Common sources of 1099-INT income include:
The form includes the institution's name and tax identification number, your personal information, and the total interest paid during the calendar year.
Not everyone who earns interest gets a 1099-INT. The institution's reporting threshold determines whether you'll receive one. While thresholds can vary slightly, many institutions issue a form if you earned at least a certain minimum amount of interest—commonly around $10 in a calendar year, though some institutions may have different thresholds. Check with your specific bank or financial institution for their reporting requirements.
If you earned interest below the threshold, you still owe taxes on it, but you may not receive a 1099-INT. In that case, you'll need to track the interest yourself and report it on your tax return.
Financial institutions must send 1099-INT forms to taxpayers by January 31st of the year following the tax year in which the interest was earned. The IRS receives a copy at the same time.
Interest income reported on a 1099-INT is taxable income. You'll need to include it when you file your federal income tax return. Most filers report this on:
The IRS already has a copy of your 1099-INT, so they'll expect to see it reported. Failing to report it can trigger IRS notices or penalties.
Before filing, verify that the information on your 1099-INT is correct:
If you find an error, contact the issuing institution immediately and request a corrected 1099-INT (marked as a correction).
You don't need to attach the 1099-INT to your tax return, but keep it for your records for at least three to seven years in case of an IRS audit or question about your return.
Interest is taxed as ordinary income, which means it's added to your total income and taxed at your marginal tax rate. Unlike some investments that may qualify for preferential tax treatment, interest income has no special tax break—it's simply added to your other income sources.
For example, if you're in a higher tax bracket due to other income, that same interest may be taxed at a higher rate. The variables that affect your actual tax liability include:
If you have accounts at different institutions, you may receive multiple 1099-INT forms—one from each institution that paid you interest. You'll need to combine all the interest amounts on your tax return.
Some people receive dozens of these forms, especially if they have multiple CDs, money market accounts, or investment accounts. Organizing them in a spreadsheet as they arrive can make tax filing easier.
If you earned a very small amount of interest and didn't receive a 1099-INT, you still must report it if you're required to file a return. The lack of a form doesn't exempt that income from taxation. You'll need to keep your own records of the interest earned—your year-end account statements often show this information.
A 1099-INT is simply the financial institution's way of reporting interest you earned and helping both you and the IRS track income that's subject to tax. Whether you receive one depends on the amount of interest earned and the institution's reporting threshold. Regardless, any interest income you earn must be reported on your tax return, and understanding how to handle it correctly helps ensure accurate filing and avoids potential IRS issues.
If you're unsure about your filing obligations or how to report multiple sources of interest income, consulting a tax professional can provide guidance tailored to your complete financial picture.
