Yes, you must report checking account interest on your tax return

Any interest your bank pays you on a checking account is taxable income to the IRS, even if the amount is small. The bank will send you a Form 1099-INT in January if the interest totals $10 or more for the year. If you earned less than $10, the bank does not have to send the form, but you still owe tax on that interest — you have to report it yourself.

The IRS knows about your interest income because the bank reports it directly to them on the same Form 1099-INT they send to you. If you do not report it on your return and the IRS sees the 1099-INT in their records, they will catch the mismatch and send you a bill for the unpaid tax plus penalties and interest charges.

Most checking accounts earn very little interest — often less than $1 per year — so the tax owed is usually small. But the reporting requirement applies no matter the amount.

Key Takeaways

  • You must report all checking account interest on your tax return, even amounts under $10 that the bank does not report to the IRS.
  • The bank sends Form 1099-INT to you and the IRS if interest reaches $10 or more in a calendar year.
  • Interest income is reported on Schedule 1 (Form 1040) or Schedule B (Form 1040) if you have other investment income.
  • The tax owed depends on your overall income and tax bracket, but even small interest amounts must be included.
  • If you do not report interest that appears on a 1099-INT the IRS receives, the agency will identify the discrepancy and assess penalties.

Where to report checking account interest on your return

If your only interest income is from your checking account and it totals $1,500 or less, you report it on Schedule 1 (Form 1040), line 8a. Write the total amount of interest from all sources — checking, savings, money market accounts, and any other interest-bearing accounts.

If you have more than $1,500 in interest income from multiple sources, or if you also have dividend income, you must file Schedule B (Form 1040) instead. Schedule B requires you to list each account separately and show the interest from each one. Your tax software will usually prompt you to file Schedule B automatically if your income crosses that threshold.

The interest amount goes into your total income for the year, which affects your tax bracket and may reduce certain deductions or credits you would otherwise receive. Even $5 in interest can change your tax outcome if you are close to an income threshold.

How to find your checking account interest on the 1099-INT

Your bank mails Form 1099-INT by January 31 each year. The form shows interest paid in box 1 (labeled "Interest income"). If you have multiple accounts at the same bank, they may combine the interest on one form or send separate forms for each account — it depends on the bank's system.

Some banks also let you download the 1099-INT from your online account portal before the paper copy arrives. If you cannot find it by late February, contact your bank directly and ask them to resend it or confirm the amount. Keep the form with your tax records.

If you earned interest but did not receive a 1099-INT because the amount was under $10, you still need to report it. Check your account statements from December to see the year-to-date interest total, or log into your online banking and look for an annual interest summary.

Interest income under $10 and reporting requirements

Banks are not required to send a 1099-INT for interest under $10, but that does not mean you can skip reporting it. The IRS expects you to report all taxable income, and interest is taxable income regardless of the amount.

In practice, very few people owe significant tax on interest under $10 because the tax itself is usually less than $2. But if the IRS audits your return and finds unreported interest, they will assess tax, penalties, and interest charges on the full amount, which can cost more than the original tax owed.

The safest approach is to add up all interest from your statements and include it on your return, even if no 1099-INT arrives. If you use tax software, you can enter the amount manually on Schedule 1 or Schedule B.

What happens if you do not report checking account interest

If the IRS receives a 1099-INT from your bank showing interest income you did not report on your return, they will identify the discrepancy through their automated matching system. The IRS will then send you a notice proposing additional tax, plus a failure-to-pay penalty (usually 0.5% per month of the unpaid tax) and interest on the unpaid amount.

The penalty and interest can easily double or triple the original tax owed. For example, if you owed $15 in tax on $100 of unreported interest and did not pay for a year, you might end up owing $25 or more by the time the IRS sends the bill.

If you discover you missed reporting interest from a prior year, you can file an amended return (Form 1040-X) for that year. Filing an amendment before the IRS contacts you often results in lower or waived penalties, though you will still owe the tax and interest.

High-yield savings and money market accounts

High-yield checking, savings, and money market accounts often pay significantly more interest than traditional checking accounts — sometimes $50 to $500 or more per year depending on your balance and the account type. These accounts follow the same reporting rules: the bank sends a 1099-INT if interest reaches $10, and you report the total on your tax return.

If you moved money between accounts during the year or opened a new account, make sure you receive a 1099-INT from each institution that paid interest. Some people miss interest income because they assume one bank reported everything, when in fact they have accounts at multiple banks.

Keep records of which accounts earned interest and how much. If you receive multiple 1099-INT forms, add them together and report the total on your return.

Frequently Asked Questions

What if my bank paid me interest but did not send a 1099-INT?

If interest was under $10, the bank is not required to send the form. You still must report it on your return using your account statements. If interest was $10 or more and you did not receive a 1099-INT by early February, contact the bank and ask them to send it or confirm the amount in writing.

Can I deduct bank fees against my interest income?

No. You report the full interest amount the bank paid you, and bank fees are not deductible against it. Certain investment-related fees may be deductible in limited cases, but routine checking account fees are not.

Do I report interest from a joint checking account differently?

The bank reports the full interest amount on the 1099-INT, but you and the account holder must decide how to split it for tax purposes. If you own the account equally, you each report half. The bank does not split the 1099-INT automatically, so you may need to contact them to request separate forms or adjust the reported amount on your return.

What if I had a checking account for only part of the year?

Report only the interest earned during the months you held the account. The 1099-INT will show the total for the full year if the account was open all year, but if you opened or closed it mid-year, the form will reflect only the interest earned while the account was active.

Does reporting interest income affect my tax refund?

Yes. Interest income increases your total taxable income, which may lower your refund or increase the tax you owe. The impact depends on your overall income and tax situation. If you are close to a tax bracket threshold or a credit phase-out, even small interest amounts can change your outcome.
