You pay taxes on interest your checking account earns, but not on the account balance itself
The money sitting in your checking account is not taxable. You do not owe federal income tax on $5,000 or $50,000 in your account just because it sits there. But if your bank pays you interest on that balance, that interest counts as income and you report it on your tax return.
Most checking accounts earn little to no interest, so many people never face this issue. But some banks offer high-yield checking accounts that pay 4% to 5% annual interest, and those accounts generate taxable income you need to report.
The bank will send you a form called a 1099-INT (Interest Income) if you earned $10 or more in interest during the year. You use that form to report the interest on your federal tax return. Some states also tax interest income, depending on where you live and file.
Key Takeaways
- Interest earned on a checking account is taxable income; the account balance itself is not.
- Banks send a 1099-INT form when interest reaches $10 or more in a calendar year.
- You report checking account interest on your federal tax return, usually on Schedule 1 (Form 1040).
- State income tax on interest varies by state; some states do not tax interest income at all.
- Interest rates on checking accounts change frequently, so your tax liability can shift year to year.
How the 1099-INT form works and when you receive it
Your bank calculates all interest paid to your checking account during the calendar year (January 1 through December 31) and reports it to you and the IRS on a 1099-INT. You should receive this form by January 31 of the following year. If you earned less than $10 in interest, the bank does not have to send you a 1099-INT, but you still owe tax on that interest if you file a return.
The 1099-INT shows the total interest in Box 1. That is the number you use to report income. If you have multiple checking accounts at different banks, you will receive a separate 1099-INT from each bank. You add all of them together when you file.
Keep your 1099-INT forms with your tax records. You do not send them to the IRS with your return, but the IRS receives a copy directly from the bank, so the numbers need to match what you report.
Where to report checking account interest on your tax return
On the federal level, you report interest income on Schedule 1 (Form 1040), which is part of the standard 1040 tax return. The interest goes on Line 8z, labeled "Interest." You add this to your other income sources to calculate your total income for the year.
If you use tax software (TurboTax, H&R Block, TaxAct, or others), the software will ask you about interest income and place it in the correct spot automatically. If you file by hand or with a tax professional, they will know where to put it.
State tax forms vary. Some states have a separate schedule for interest income; others include it on the main state return. Your state tax form instructions will tell you where to report it. If your state does not have an income tax (like Florida, Texas, or Wyoming), you do not file state income tax at all, so there is nothing to report there.
How much tax you actually owe on checking account interest
The amount of tax depends on your total income and your tax bracket. Interest is taxed as ordinary income, meaning it is added to your wages, self-employment income, and other sources, and the total is taxed at your marginal rate.
If you earn $50,000 a year and your checking account pays you $200 in interest, that $200 is added to your $50,000, making your taxable income $50,200. The tax on that extra $200 depends on your bracket. For someone in the 22% federal bracket in 2024, that $200 in interest costs roughly $44 in federal tax. For someone in the 12% bracket, it costs about $24.
You do not pay tax on the interest until you file your return. The bank does not withhold it automatically (unless you ask them to). This means you may owe money when you file, or you may have already paid enough in withholding from your job that you still get a refund.
State taxes on checking account interest
Most states that have an income tax also tax interest income the same way the federal government does. But some states treat interest differently or do not tax it at all.
Nine states have no income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only interest and dividends, but many people do not owe because of high exemption thresholds). If you live in one of these states, you do not owe state tax on your checking account interest.
If you live in a state with income tax, check your state's tax form instructions or contact your state tax authority to confirm where to report interest. The process is similar to federal reporting—you receive a 1099-INT from the bank and report the amount on your state return.
What happens if you do not report checking account interest
The IRS receives a copy of every 1099-INT your bank sends you. If you do not report the interest on your return, the IRS will likely notice the mismatch between what the bank reported and what you filed. This can trigger a notice asking you to explain the difference or pay the tax owed plus penalties and interest.
The penalty for not reporting income is usually 20% of the unpaid tax, plus interest that accrues daily. If the IRS determines it was intentional fraud rather than an honest mistake, penalties can be higher. It is much simpler to report the interest when you file.
If you discover you missed reporting interest in a prior year, you can file an amended return (Form 1040-X) for that year. The sooner you do this, the lower the interest charges will be.
How high-yield checking accounts affect your taxes differently
A standard checking account at a large bank pays 0.01% to 0.05% interest, which generates almost no taxable income. A high-yield checking account at an online bank or credit union might pay 4% to 5%, which generates real income you have to report.
If you keep $10,000 in a high-yield checking account paying 4.5%, you earn $450 in interest per year. That $450 is taxable income. If you keep $25,000 in the same account, you earn $1,125, which is also taxable. The higher the rate and the larger your balance, the more tax you owe.
This does not mean high-yield accounts are a bad choice—the interest you earn usually exceeds the tax you pay. But it is worth factoring into your decision if you are comparing accounts. A high-yield savings account (not a checking account) works the same way: interest is taxable.
Frequently Asked Questions
Do I owe taxes on money I transfer into my checking account?
No. Transfers of your own money—from savings, from a paycheck, from selling something—are not income and not taxable. Only interest the bank pays you is taxable. The money itself is yours and has already been taxed when you earned it.
What if my checking account interest is less than $10?
You still owe tax on it, but the bank does not have to send you a 1099-INT. You are responsible for reporting it. Keep track of your interest statements throughout the year and report the total on your return, even if it is $3 or $7.
Can I deduct checking account fees to offset the interest income?
No. Miscellaneous unreimbursed employee expenses and investment fees were deductible under prior tax law, but that deduction was suspended from 2018 through 2025. Checking account fees cannot be deducted against interest income on your current return.
Do I report interest from a joint checking account differently?
If the account is truly joint and both owners contributed equally, you and the other owner typically split the interest 50/50 for tax purposes. The bank may report all the interest to one person's Social Security number, so you may need to file an amended return or attach a note explaining the split. Consult a tax professional if the ownership is unequal.
What if I closed my checking account mid-year?
The bank reports all interest earned from January 1 through the day you closed the account. You report that full amount on your tax return for that year, even though you only had the account for part of the year.
