Yes, you must report all interest income from a checking account, no matter how small
The IRS requires you to report every dollar of interest your bank pays you on a checking account. This includes money market checking accounts and interest-bearing checking products. The bank will send you a Form 1099-INT if the interest reaches $10 or more in a calendar year, but you owe tax on the interest even if you don't receive a 1099-INT — and even if the amount is $5 or less.
The reason is straightforward: interest is income. Your bank is paying you for the use of your money, and the IRS treats that payment the same way it treats wages or investment returns. You report it on your tax return, and you pay tax on it at your ordinary income tax rate.
Most checking account interest is small enough that it makes little practical difference to your tax bill. But the reporting requirement itself has no dollar threshold. If your account earned $2.47 in interest, you report $2.47.
Key Takeaways
- You must report all checking account interest on your federal tax return, regardless of the amount.
- Banks send Form 1099-INT only when interest reaches $10 or more, but you report interest below that threshold yourself.
- Interest income goes on Schedule 1 (Form 1040) and is taxed at your ordinary income tax rate.
- If you have multiple accounts at different banks, each bank reports separately, and you add all interest together on your return.
- Failing to report interest income can trigger an IRS notice, even though the amount is usually small.
When the bank sends you Form 1099-INT
Your bank will mail or electronically deliver a Form 1099-INT by January 31 of the year after the interest was paid if you earned $10 or more in interest during the calendar year. The form shows the total interest paid to you in box 1. You receive a copy, and the bank sends a copy to the IRS.
If you have accounts at multiple banks, you will receive a separate 1099-INT from each bank that paid you $10 or more. You add all the interest together when you file your return. The IRS will have received copies of all those forms, so they will be cross-checking your return against them.
If your interest was less than $10, the bank does not send a 1099-INT. You still owe tax on it, and you still report it — you just have to find the amount yourself by looking at your year-end statement or online banking records.
Where to report checking account interest on your tax return
Interest income goes on Schedule 1 (Additional Income and Adjustments to Income), which is part of Form 1040. On Schedule 1, line 8 is labeled "Interest." You enter the total of all interest you received from all sources — checking accounts, savings accounts, CDs, bonds, and any other interest-bearing accounts.
That amount then flows to your Form 1040, where it becomes part of your total income. It is taxed at your ordinary income tax rate, which depends on your tax bracket for the year.
If you use tax software, it will usually ask you directly whether you received interest income and prompt you to enter the amount. If you file by hand or with a tax professional, bring documentation of all interest received — your 1099-INT forms and statements for any accounts that paid less than $10.
Interest below $10 and accounts you need to track yourself
Banks are not required to send a 1099-INT for interest under $10, which means you have to find and report it yourself. This happens most often with checking accounts that pay very low rates, or accounts that were opened late in the year.
To find the interest you earned, log into your online banking or request a year-end statement from your bank. The statement will show deposits labeled as "interest" or "interest paid." Add up all of those deposits for the calendar year. That is the amount you report on Schedule 1.
The IRS does not know about this interest unless you report it, because the bank did not send them a 1099-INT. But you are still legally required to report it. Leaving it off your return is underreporting income, which can result in a notice from the IRS if they audit your return or cross-check it against other information they have.
How interest income affects your tax bill
Interest is taxed as ordinary income at your marginal tax rate — the rate that applies to your highest dollar of income. If you are in the 22% tax bracket, $100 of interest costs you $22 in federal tax. If you are in the 12% bracket, it costs $12.
For most people with checking accounts, the interest is small enough that it barely moves the needle. A checking account earning 4% APY on a $5,000 balance generates about $200 per year in interest, which would cost roughly $44 to $66 in federal tax depending on your bracket. But the reporting requirement exists regardless of the size.
Interest income can also affect other parts of your return. If you are close to an income threshold for a tax credit or deduction, additional interest income might push you over that threshold and reduce your benefit. This is rare with checking account interest, but it is worth knowing.
What to do if you don't receive a 1099-INT
If you earned $10 or more in interest and your bank did not send you a 1099-INT by February 15, contact the bank and ask for it. Banks sometimes mail them late, or they may have sent it to an old address if you moved during the year.
If the bank confirms they sent it and you still have not received it after 30 days, you can file your return using the interest amount shown on your year-end statement. Keep that statement with your records. If the IRS later receives the 1099-INT and it does not match your return, you can show the IRS your statement to prove you reported the correct amount.
If you earned less than $10 in interest, there is no 1099-INT to receive. You report the interest based on your bank statement, and you keep the statement in your records in case the IRS ever asks.
Joint accounts and who reports the interest
If you have a joint checking account with another person, the bank will send a 1099-INT in the name of the first account owner listed on the account. That person is responsible for reporting the interest on their tax return, even if both owners contributed equally to the account.
If you and the other owner want to split the interest income for tax purposes, you can do that, but you have to report it correctly. The person who received the 1099-INT reports the full amount, then files Form 8082 (Notice of Inconsistent Treatment) to explain that they are splitting it with the other owner. The other owner reports their share on their return. This is uncommon and can complicate your filing, so discuss it with a tax professional if you need to split interest income.
Frequently Asked Questions
What if I earned $8 in checking account interest and no 1099-INT arrived?
You still report the $8 on Schedule 1, line 8 of your Form 1040. The bank does not send a 1099-INT for amounts under $10, so you have to find the interest on your statement and enter it yourself. Keep your year-end statement in case the IRS asks for proof.
Do I report interest from a savings account the same way as checking account interest?
Yes. All interest income — from checking, savings, money market accounts, CDs, and any other bank product — goes on the same line (Schedule 1, line 8). You add them all together and report the total.
Can I deduct bank fees from the interest I report?
No. You report the full interest amount the bank paid you. Bank fees are not deductible on your federal tax return (though some states allow limited deductions for certain fees). You report interest and pay fees separately.
What if my checking account earned interest but the bank made an error and didn't report it?
You still report it. You are responsible for reporting all income you received, whether or not the bank reported it to the IRS. If the IRS later discovers the unreported interest, you will owe tax plus penalties and interest on the unpaid amount.
Does interest from a checking account count toward the standard deduction?
No. Interest is income, and it increases your total income. It does not reduce your standard deduction. Your standard deduction is a fixed amount based on your age and filing status.
