Interest counts as taxable income on your federal return

The interest your bank pays you on a savings account is taxed as ordinary income by the IRS. That means you report it on your tax return the same way you would report wages or salary, and it's taxed at your regular income tax rate—not at a special lower rate.

Your bank will send you a Form 1099-INT in January if you earned $10 or more in interest during the previous year. This form lists all the interest paid to your account and goes to both you and the IRS. You then report that amount on your federal tax return, typically on Schedule 1 (Form 1040) or directly on Form 1040 itself, depending on your filing situation.

Most states also tax savings account interest as income, though a few states—including New Hampshire and Tennessee—do not tax interest income. If you live in a state with an income tax, you'll report the same interest amount on your state return as well.

Key Takeaways

  • Banks report interest of $10 or more annually on Form 1099-INT, which the IRS receives at the same time you do.
  • You must report all savings account interest on your federal tax return, even if you don't receive a 1099-INT form.
  • Interest is taxed at your regular income tax rate, which depends on your total income and filing status for the year.
  • Most states tax savings account interest, but New Hampshire and Tennessee do not tax interest income.
  • If your bank fails to send a 1099-INT or sends one with an error, you still owe tax on the interest you actually earned.

When you receive a Form 1099-INT and what it means

The Form 1099-INT arrives by January 31 each year if your interest earnings crossed the $10 threshold. The form shows the account holder's name, Social Security number or tax ID, the bank's name, and the total interest paid during the year. It comes in two copies: one for you to keep with your tax records, and one that the bank sends to the IRS.

The IRS matches the 1099-INT it receives from your bank against the interest income you report on your return. If the numbers don't match, the IRS will contact you. This is why it's critical to report the exact amount shown on the form, even if you think the figure is wrong—if there's a discrepancy, you'll need to contact your bank and file an amended return if necessary.

If you earned interest but didn't receive a 1099-INT because the amount was under $10, you still owe tax on that interest. You'll report it on your return based on your own records or your year-end account statement.

How interest income affects your tax bracket and refund

Interest income is added to your other income for the year, which can push you into a higher tax bracket. For example, if you earned $50,000 in wages and $500 in savings account interest, your taxable income is $50,500. That extra $500 may increase the tax you owe, reduce a refund you were expecting, or move you into a higher bracket if you're close to a threshold.

The tax impact depends on your total income, filing status, and whether you take the standard deduction or itemize. Someone in the 22% tax bracket will owe roughly $110 in federal tax on $500 of interest, while someone in the 12% bracket will owe about $60. State taxes add on top of that.

If you're expecting a refund and your interest income is higher than usual, that refund may be smaller. Conversely, if you owe taxes, the interest income will increase what you owe.

Interest from different account types and special cases

Interest from regular savings accounts, money market accounts, and certificates of deposit (CDs) all count as taxable income. High-yield savings accounts, which pay more interest than traditional savings accounts, are also fully taxable—the higher rate doesn't change the tax treatment.

Interest from bonds and bond funds is also taxable, though municipal bonds issued by state and local governments are usually exempt from federal tax (and sometimes state tax). Treasury bonds and bills are taxed by the federal government but exempt from state and local taxes. If you own any of these, you'll receive separate 1099 forms.

If you're a minor with a savings account, your parent or guardian reports the interest on their return if you're claimed as a dependent. Once you file your own return, you report your own interest income.

What to do if you didn't receive a 1099-INT or it has an error

Contact your bank directly if you expected a 1099-INT but didn't receive one by February 15. Ask them to issue a corrected form or confirm whether your interest fell below the $10 reporting threshold. Keep a copy of any email or written confirmation from the bank.

If the 1099-INT shows the wrong amount, ask your bank to issue a corrected form (called a "corrected 1099-INT"). The bank will send the corrected version to you and the IRS. Wait until you receive the corrected form before filing your return, if possible. If you've already filed and the amount was wrong, you'll need to file an amended return (Form 1040-X) once the corrected 1099-INT is issued.

If you earned interest that your bank didn't report—for example, interest from a very small account at a credit union—you still report it on your return. The IRS won't have a record of it from the bank, but you're still legally required to include it.

Planning ahead to manage interest income taxes

If you have a large savings balance earning significant interest, you might consider how that interest will affect your tax situation. Some people spread money across multiple accounts or institutions to manage the timing of interest payments, though this doesn't reduce the total tax owed—it just changes when you owe it.

If you're retired or on a fixed income and concerned about how interest income will affect your taxes, benefits, or Medicare premiums, talk to a tax professional. Interest income can sometimes trigger additional taxes or affect your may be able to access for certain tax credits.

Keep your bank statements and 1099-INT forms for at least three years in case the IRS asks questions about your reported income. Digital copies are fine as long as they're clear and complete.

Frequently Asked Questions

Do I have to report interest if I earned less than $10?

Yes. The $10 threshold only determines whether your bank sends you a 1099-INT form. You must report all interest you earned on your tax return, regardless of the amount. Check your year-end account statement to find the exact figure.

Can I deduct the taxes I pay on savings account interest?

No. Interest income is taxed, but you cannot deduct the tax itself. You can only deduct certain investment expenses in limited situations, and savings account interest doesn't may have access to.

What if I moved money between banks during the year?

Each bank reports only the interest it paid you while you held an account there. You may receive multiple 1099-INT forms if you had accounts at different banks. Add up all the interest from all forms and report the total on your return.

Does interest from a joint savings account get split between owners for tax purposes?

The bank reports all interest to the primary account holder on the 1099-INT. If the account is truly joint and you each own half, you may need to split the reported interest between you and your co-owner when filing your returns. Discuss this with a tax professional if you're unsure how to handle it.

Will interest income affect my student loan repayment plan or other benefits?

Interest income counts as income for many benefit programs, including income-driven student loan repayment plans, SNAP, and housing assistance. If you receive any means-tested benefits, report your interest income accurately and contact the program administrator if you think it will affect your status.
