Yes, you must report checking account interest as income
Any interest your checking account earns counts as taxable income. The IRS treats it the same way it treats interest from savings accounts, money market accounts, or certificates of deposit. If your bank paid you interest during the year, that amount goes on your tax return, even if it was only a few dollars.
The threshold for reporting is low. You do not need to earn a minimum amount before the interest becomes taxable—even $1 in interest must be reported. However, your bank only sends you a formal notice (Form 1099-INT) if the interest reaches $10 or more in a calendar year. If you earned less than $10, you still owe tax on it, but you will not receive a 1099-INT.
Most checking accounts earn little to no interest, so many people never face this issue. But high-yield checking accounts, which have become more common, can generate reportable interest. If you moved money to one of these accounts, you need to know what to report and where.
Key Takeaways
- All checking account interest is taxable income, regardless of the amount, and must be reported on your tax return.
- Your bank sends Form 1099-INT only if interest reaches $10 or more in the calendar year, but you report any amount you earned.
- Interest goes on Schedule 1 (Form 1040) under "Interest" and is added to your total income for the year.
- If your bank reports interest on a 1099-INT but you believe the amount is wrong, contact the bank to request a corrected form before filing.
- Keeping your own records of interest earned protects you if there is a discrepancy between what you earned and what the bank reports.
Where checking account interest appears on your tax forms
Interest income goes on Schedule 1 (Form 1040), Part I, line 8. This is the form where you report all types of income beyond wages. If you have interest from multiple sources—a checking account, savings account, and a CD, for example—you add them together and enter the total on that single line.
If you received a Form 1099-INT from your bank, the interest amount is already printed on that form. You use the figure from the 1099-INT when you fill out Schedule 1. If you earned interest but did not receive a 1099-INT (because it was under $10), you write in the amount you earned based on your own records or your bank statements.
The interest you report becomes part of your adjusted gross income (AGI), which affects your tax bracket and may change the amount of tax you owe or the refund you receive. Even small amounts of interest can matter if you are close to an income threshold for a tax credit or deduction.
How to find the interest amount if you did not receive a 1099-INT
If your checking account earned less than $10 in interest, your bank will not send you a 1099-INT. You will need to find the amount yourself. Log into your online banking portal and look for a year-end summary or interest statement. Most banks show total interest earned in the account details or in a downloadable annual statement.
If you cannot find it online, call your bank's customer service line or visit a branch. Tell them you need the total interest earned on your account for the tax year. They can provide this in minutes. Write down the exact amount and keep it with your tax records.
Another option is to add up the interest deposits yourself by reviewing your monthly statements. Interest usually posts on the last day of the month or the first day of the next month. If you see small deposits labeled "interest" or "INT," add them together for the year.
What to do if the 1099-INT amount looks wrong
If your bank sent you a 1099-INT but the interest amount does not match what you see in your account, contact the bank before you file your return. Do not assume the bank is correct—errors happen, especially if you opened or closed the account mid-year, or if the account was transferred from another bank.
Call the bank's customer service number on the back of your debit card or visit a branch. Explain that the 1099-INT interest total does not match your records. Ask them to review the calculation. If they find an error, they will issue a corrected Form 1099-INT (marked as a correction) and send it to you and the IRS.
Keep the corrected 1099-INT with your tax records. If you already filed your return with the wrong amount, you can file an amended return (Form 1040-X) once you have the corrected form. The IRS will adjust your tax liability based on the corrected interest amount.
Interest from joint checking accounts and how to report it
If you own a checking account jointly with another person, the interest earned belongs to both of you unless you have a written agreement saying otherwise. The bank will issue a single 1099-INT in the name of the account owner listed first, but both owners are responsible for reporting their share of the interest on their own tax returns.
You and the other account owner should decide how to split the interest. If you contributed equally, you each report half. If one person contributed more, you can split it based on contribution percentages. The IRS does not require you to prove the split, but you should keep a record of how you divided it in case of an audit.
If the 1099-INT was issued in only one person's name, that person may need to file an amended return to correct it, or you may both need to report the interest on your separate returns and keep documentation of the split. This is a situation where talking to a tax professional can save confusion.
Interest from accounts held in trust or for a minor
If you hold a checking account in trust for a minor or as a custodian, the interest is taxable to the minor, not to you. The bank will issue the 1099-INT in the minor's name and Social Security number. The minor (or their parent or guardian) must report this interest on a tax return, even if the minor has no other income.
A minor with only interest income may not owe federal income tax if the amount is below the standard deduction for that year, but a return may still need to be filed to claim a refund of any taxes withheld. Check the IRS website or a tax professional for the current standard deduction for dependents.
If you are the custodian or trustee, make sure the bank has the correct Social Security number on file for the account. If the 1099-INT is issued in your name instead of the minor's, contact the bank to correct it before the tax important date.
Keeping records of checking account interest for tax purposes
Save all 1099-INT forms you receive, along with your bank statements for the year. If you earned interest under $10 and did not receive a 1099-INT, keep a note of the amount and how you calculated it. These records protect you if the IRS ever questions your return.
If you use tax software or work with a tax professional, have your 1099-INT or interest documentation ready when you file. If you file on your own, keep copies of everything you submitted with your return for at least three years. The IRS can audit returns going back three years in most cases, and longer if there is a significant error.
If you move banks or close an account during the year, make sure you have the interest statement from the old bank before closing it. Some banks do not send 1099-INT forms until January, so do not assume you have received everything until mid-February.
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 income on your tax return, no matter how small. If you earned $3 in interest, you report $3.
What if I earned interest but my bank did not send a 1099-INT?
Contact your bank and ask for the total interest earned on your account for the year. They can provide this information even if the amount was under $10. Use that figure when you fill out Schedule 1 on your tax return.
Can I deduct the taxes I paid on checking account interest?
No. Interest income is taxed as ordinary income. You cannot deduct it. However, if taxes were withheld from the interest, you may receive a credit for those taxes when you file your return.
If I have multiple checking accounts, do I report interest from each one separately?
No. Add up the interest from all your checking accounts (and any other interest-bearing accounts) and enter the total on one line of Schedule 1. You do not need to list each account separately.
What happens if my bank reports the wrong amount on the 1099-INT?
Contact your bank when ready and ask them to issue a corrected 1099-INT. Once you have the corrected form, use that amount on your tax return. If you already filed with the wrong amount, file an amended return (Form 1040-X) with the correct figure.
