Where interest income goes on your tax return

Interest from a savings account is reported on Schedule B (Interest and Ordinary Dividends), which attaches to your Form 1040. If your total interest income for the year is $1,500 or less and you have no other investment income, you can report it directly on line 2b of Form 1040 instead — but most people use Schedule B because it's clearer and easier to track.

Your bank sends you a Form 1099-INT by January 31 each year. This form shows exactly how much interest you earned in that calendar year. The amount on box 1 of the 1099-INT is what you report. If you earned interest from multiple banks or accounts, you'll receive a separate 1099-INT from each one, and you add them all together on Schedule B.

The interest is taxed as ordinary income at your regular tax rate — it's not a capital gain. This means it's added to your wages, self-employment income, and other income to determine your total taxable income for the year.

Key Takeaways

  • Interest income appears on Schedule B (or directly on Form 1040 if under $1,500), using the amount shown in box 1 of your Form 1099-INT.
  • Your bank mails the 1099-INT by January 31, and you must report the same amount the bank reports to the IRS or face a mismatch notice.
  • If you don't receive a 1099-INT but earned interest, contact your bank — they may have sent it to an old address or you may need to request it.
  • Interest is taxed as ordinary income, not as a capital gain, so it increases your overall taxable income for the year.
  • You report each 1099-INT separately on Schedule B, then transfer the total to Form 1040.

Understanding the Form 1099-INT your bank sends

The 1099-INT has multiple boxes, but box 1 is the one you need for your tax return. Box 1 shows interest income — the total amount of interest your account earned during the calendar year. This is the number you enter on Schedule B, line 1 (or on Form 1040 line 2b if you're reporting it there instead).

Other boxes on the 1099-INT may show early withdrawal penalties (box 2), U.S. Savings Bond interest (box 3), or federal income tax already withheld (box 4). If your bank withheld tax, that amount appears in box 4, and you'll claim it as a payment when you file. Most savings accounts don't have withholding, but some do if you earned a large amount or requested it.

The 1099-INT is issued in two copies: one goes to you, one goes to the IRS. The IRS matches what you report on your return to what the bank reported to them. If the numbers don't match, you'll receive a notice. Always report the same amount the bank shows in box 1.

What to do if you earned interest but didn't receive a 1099-INT

Banks are required to send a 1099-INT if you earned $10 or more in interest during the year. If you earned less than $10, no form is issued, but you still report the interest on your return. Check your bank statements to find the exact amount and report it on Schedule B.

If you earned $10 or more and didn't receive a 1099-INT by February 15, contact your bank directly. The form may have been mailed to an old address on file, or there may be a delay. Ask the bank to reissue it or provide the interest amount in writing. You can also request it through your online banking portal — many banks allow you to download 1099-INTs there.

If the bank cannot locate a 1099-INT and you have no record of the interest amount, use your account statements. Add up the interest deposits for each month from January through December. Report that total on Schedule B, and keep your statements as backup in case the IRS asks questions later.

How to fill out Schedule B with your interest income

Schedule B has two parts: Part I for interest income and Part II for dividends. You only need to complete Part I. In the first column, list the name of each bank or financial institution. In the second column, enter the interest amount from box 1 of each 1099-INT.

If you have interest from only one account, you can skip Schedule B entirely and report the amount directly on Form 1040, line 2b. But if you have multiple accounts or want a clear record, Schedule B is the better choice. Add up all the interest amounts in Part I and enter the total on line 4 of Schedule B. This total then transfers to Form 1040, line 2b.

Schedule B also asks whether you're a U.S. citizen and whether you had a foreign account. For most people with domestic savings accounts, the answer to both is straightforward. If you did have a foreign account with more than $10,000 at any point during the year, you may need to file additional forms (FBAR or FATCA), but that's separate from reporting the interest itself.

Reporting interest when you file jointly or separately

If you're married and file a joint return, combine all interest from both spouses' accounts on one Schedule B. List each account separately by the account holder's name, then add them all together. The combined total goes on Form 1040, line 2b.

If you file separately, each spouse reports only their own interest income on their own Schedule B and Form 1040. Make sure your bank has the correct Social Security number on file for each account, because the 1099-INT will be issued under that number. If a 1099-INT is issued under the wrong name or number, contact your bank to correct it before you file.

What happens if the interest amount on your return doesn't match the 1099-INT

The IRS receives a copy of every 1099-INT issued. If you report a different amount than what appears on the form, the IRS will send you a CP2000 notice (Examination of Your Return) asking you to explain the difference. This doesn't mean you're in trouble — it's just a mismatch that needs to be cleared up.

If you made an honest error, you can respond to the notice with a corrected amount and explanation. If your bank issued the 1099-INT incorrectly, you can provide documentation from the bank showing the correct amount. Keep copies of your bank statements and any correspondence with your bank to support your response.

The safest approach is to report exactly what the bank shows on the 1099-INT. If you believe the 1099-INT is wrong, contact your bank first and ask them to issue a corrected form (called an amended 1099-INT) before you file your return. This avoids the need to respond to an IRS notice later.

Interest income and your tax bracket

Interest is added to all your other income to calculate your total taxable income for the year. Depending on how much interest you earned and what your other income is, it may push you into a higher tax bracket. For example, if you earned $500 in interest and your other income was already near the top of the 12% bracket, that $500 might be taxed at 22%.

This is why it's important to know your interest income before you file — it affects not just how much tax you owe on the interest itself, but potentially your overall tax rate. If you expect to earn a significant amount of interest, you might consider spreading it across multiple years or exploring higher-yield savings accounts in lower-tax states (though state tax rules vary widely).

Interest income also counts toward your modified adjusted gross income (MAGI), which determines whether you're may be able to access for certain tax credits and deductions. If your MAGI exceeds certain thresholds, you may lose may be able to access for the Earned Income Tax Credit, education credits, or other benefits. Check the instructions for any credits you claim to see whether interest income affects them.

Frequently Asked Questions

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

Yes. The bank doesn't send a 1099-INT for amounts under $10, but you still report the interest on your return. Use your bank statements to find the exact amount and enter it on Schedule B or Form 1040, line 2b. The $10 threshold is only for when the bank must issue a form, not for when you must report it.

What if my bank issued a 1099-INT but I think the amount is wrong?

Contact your bank and ask them to verify the calculation. If they confirm it's wrong, request a corrected 1099-INT (an amended form). If they confirm it's correct but you disagree, ask for a detailed breakdown of interest by month. Keep all documentation. If you file with a different amount, be ready to explain it if the IRS sends a notice.

Can I deduct any fees my bank charged against the interest income?

No. You report the full interest amount on Schedule B — you cannot reduce it by account fees or other charges. However, if you paid investment fees or advisory fees (not bank fees), those may be deductible under other rules, though deductions for investment expenses are limited under current tax law. Bank fees themselves are not deductible.

If I moved money between accounts during the year, do I report interest twice?

No. Each account earns interest separately, and each 1099-INT reports only the interest earned in that specific account. If you moved $5,000 from Account A to Account B in June, Account A reports interest earned January through May, and Account B reports interest earned June through December. You add both 1099-INTs together on Schedule B — you're not double-counting, just reporting all the interest you earned across all accounts.

What if I closed my savings account during the year?

The bank still sends a 1099-INT for the interest earned while the account was open. The form covers only the calendar year (January 1 through December 31), not the life of the account. Report the interest shown on the 1099-INT the same way you would for an active account.
