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

Any interest your bank pays you on a checking account is taxable income. The IRS requires you to report it, even if the amount is small. Your bank will send you a Form 1099-INT in January showing how much interest you earned during the previous year, and you report that figure on your tax return.

The reporting requirement applies regardless of whether you actually received a paper form. If you earned $10 in interest and your bank did not send you a 1099-INT because the amount fell below their reporting threshold, you still owe tax on that $10 if you knew about it. Most banks report all interest paid, but the legal obligation to report is yours either way.

The tax you owe on checking account interest depends on your overall income and tax bracket. A small amount of interest might not change your tax bill at all if you are in a low bracket, but you still have to include it on your return. The IRS matches the 1099-INT your bank files against your return, so omitting it can trigger a notice.

Key Takeaways

  • Your bank reports checking account interest to the IRS on Form 1099-INT, and you must include that amount on your federal tax return.
  • You are required to report all interest earned, even if the amount is under $10 or your bank did not send you a form.
  • Interest income is taxed at your ordinary income tax rate, which depends on your total income and filing status.
  • The IRS cross-checks 1099-INT forms against tax returns, so leaving interest off your return can result in a notice or audit.
  • Some states also tax interest income, so check your state tax rules in addition to federal requirements.

When your bank sends you Form 1099-INT

Banks mail Form 1099-INT by January 31 each year for interest paid during the previous calendar year. You receive one copy and the bank sends a copy to the IRS. If you have multiple checking accounts at different banks, you may receive more than one 1099-INT.

Some banks set a minimum threshold before they issue a 1099-INT—often $1 or $10—but this does not mean you can skip reporting interest below that amount. If your account earned $5 in interest and your bank did not send a form, you still report that $5 on your return. Check your monthly statements or your online banking portal to find the exact interest earned if you do not receive a form.

If you do not receive a 1099-INT by early February, contact your bank directly. Ask them to either mail a replacement or provide the interest amount in writing. You need this figure to complete your tax return accurately.

How to report interest on your tax return

On Form 1040 (the main federal income tax form), interest income goes on Line 1b under "Interest." If you use tax software, the program will ask you to enter the amount from your 1099-INT, and it automatically places it in the correct spot. If you file by hand, write the total interest from all your 1099-INT forms on that line.

If you received a 1099-INT but the amount shown is wrong, do not just ignore it. Contact your bank and ask them to issue a corrected form (called a Form 1099-INT (Corrected)). Once you receive the corrected form, report the correct amount on your return. If the IRS later matches your return against the original incorrect form, you can show them the corrected form as proof.

Interest income is added to your other income to calculate your total taxable income. This means it can push you into a higher tax bracket if you are close to a threshold, though for most people a small amount of checking account interest has minimal impact.

State tax reporting for checking account interest

Most states that have an income tax also tax interest income the same way the federal government does. You report the same 1099-INT amount on your state return. A few states—including Pennsylvania and New Hampshire—do not tax interest income, so if you live in one of those states, you may not owe state tax on your checking account interest even though you still owe federal tax.

Check your state's tax agency website or your state tax form instructions to confirm whether interest is taxable in your state. If you moved during the year, you may owe tax to two states, so look up the rules for both.

What happens if you do not report checking account interest

The IRS receives a copy of every 1099-INT your bank files. Their computer systems match these forms against the tax returns they receive. If your return shows no interest income but the IRS has a 1099-INT in your file, they will send you a notice asking why there is a discrepancy.

In many cases, the IRS will simply assess the tax you owe plus interest on the unpaid amount. If the omission was unintentional and the amount is small, you can respond to the notice, explain the error, and pay what you owe. Repeated or large omissions can trigger an audit or penalties, though penalties are often waived if you can show the error was honest.

The safest approach is to report all interest, even if the amount seems trivial. The cost of reporting is zero, and it keeps you in compliance with the law.

Interest from high-yield savings and money market accounts

The same reporting rules apply to interest from high-yield savings accounts, money market accounts, and other deposit accounts at banks or credit unions. Each account that earns interest may generate its own 1099-INT. Add up all the interest from all your accounts and report the total on Line 1b of your Form 1040.

If you have many accounts, your bank's year-end tax summary (often available in your online portal) may show total interest across all your accounts. This can save you time when gathering your tax documents.

Frequently Asked Questions

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

Yes. The IRS requires you to report all interest income, regardless of amount. Your bank may not send you a 1099-INT if interest is below their threshold, but you are still legally required to report what you earned. Check your statements to find the exact amount.

What if my bank sent me a 1099-INT but I closed the account before the end of the year?

Report the interest shown on the 1099-INT. The form reflects interest earned during the calendar year, not when you closed the account. The timing of the account closure does not change your reporting obligation.

Can I deduct any expenses related to my checking account?

No. Checking account fees and other banking costs are not deductible for most people. You report the interest as income with no offsetting deduction. If you are self-employed and use a business checking account, some banking fees may be deductible as a business expense, but personal account fees are not.

Do I need to report interest if I am not filing a tax return?

If you are required to file a return based on your income, you must report the interest. If you are not required to file, you generally do not have to report interest either. However, if your only income is checking account interest and it is below the filing threshold for your age and status, you may not be required to file—but check the IRS rules for your specific situation.

What if I earned interest in a joint account—do both owners report it?

The bank reports the full interest amount on a single 1099-INT. Only one owner's name and Social Security number appear on the form. That person reports the full amount on their return unless you and the other owner file a joint return together, in which case you report it once on your joint return. If you file separately, contact your bank to ask how they handle the reporting.
