Interest on checking accounts is taxable income
Yes, you owe federal income tax on any interest your checking account earns. The bank treats it the same way it treats wages or investment returns — as income you must report to the IRS. The amount is usually small, but the requirement is real, and the IRS tracks it.
Your bank will send you a form called a 1099-INT (Interest Income) at the end of the year if you earned $10 or more in interest during that calendar year. You then report that amount on your tax return. Some states also tax interest income, though the rules vary by state.
The tax you owe depends on your overall income and tax bracket. If you earned $500 in checking account interest and you are in the 22% federal tax bracket, you would owe roughly $110 in federal tax on that interest alone. But if you are in the 12% bracket, it would be about $60. State tax, if your state has it, adds on top of that.
Key Takeaways
- Banks report checking account interest to the IRS on a 1099-INT form if you earned $10 or more in a calendar year.
- You must report this interest as income on your federal tax return, and you owe tax on it at your marginal tax rate.
- Most checking accounts earn so little interest that the tax owed is small, but high-yield checking accounts can generate taxable interest of several hundred dollars per year.
- Some states tax interest income and some do not; check your state's rules if you live in a state with income tax.
- The IRS does not require you to pay estimated quarterly taxes on checking account interest unless your total tax liability is very high.
When the bank sends you a 1099-INT form
Your bank is required to send you a 1099-INT if the interest you earned in a calendar year totals $10 or more. The bank sends it to you and also sends a copy to the IRS, so the IRS already knows about the income before you file your return.
You will receive the form by January 31 of the year following the year you earned the interest. For example, interest you earned during 2024 will appear on a 1099-INT mailed in January 2025. The form shows the account number, the total interest earned, and sometimes a breakdown by month.
If you earned less than $10 in interest during the year, the bank does not have to send you a 1099-INT. You still owe tax on that interest if you are required to file a return, but you will not receive the form. You can find the amount by checking your monthly statements or your online account history and adding it up yourself.
How to report checking account interest on your tax return
When you file your federal income tax return, you report the interest income on Schedule 1 (Additional Income and Adjustments to Income), which attaches to Form 1040. The line is labeled "Interest" and you enter the total from your 1099-INT form or your own calculation if you did not receive a form.
This interest gets added to your other income — wages, self-employment income, investment gains, and anything else — to calculate your total taxable income for the year. Your tax bracket is then applied to that total, which means the interest is taxed at whatever your highest marginal rate is.
If you have multiple checking accounts or savings accounts at different banks, each bank will send you a separate 1099-INT. You add all of them together and report the total on Schedule 1. The IRS receives copies of all the 1099-INT forms, so reporting the combined total ensures your return matches what the IRS already knows.
Why most checking account interest is negligible
A traditional checking account at a large bank typically earns between 0.01% and 0.05% annual interest. On a $10,000 balance, that is $1 to $5 per year. The tax on $5 is less than $2 in most cases, which is why most people do not think about it.
High-yield checking accounts, offered by online banks and some credit unions, can pay 4% to 5% or higher. On a $10,000 balance, that generates $400 to $500 per year in interest. The tax on $400 at a 22% rate is $88. This is still a small amount, but it becomes worth tracking if you keep a large balance in a high-yield account.
The interest rate on checking accounts also changes over time. When the Federal Reserve raises its benchmark interest rate, banks raise the rates they pay on deposits. When the Fed cuts rates, banks cut deposit rates. Your 1099-INT will reflect whatever rate was in effect during the year you earned the interest.
State income tax on checking account interest
Whether you owe state tax on checking account interest depends on where you live. Most states with income tax tax interest income the same way the federal government does — as ordinary income at your state tax rate. A few states have special rules.
New Hampshire and Tennessee tax interest and dividend income but not wages. Illinois exempts interest income from state tax entirely. Some states exempt interest earned on accounts held by residents over a certain age. If you live in a state with income tax, check your state revenue department's website or a tax professional to confirm the rule for your situation.
If you live in a state without income tax — Florida, Texas, Wyoming, and others — you owe no state tax on checking account interest, only federal tax.
Whether you need to pay estimated quarterly taxes
The IRS requires you to pay estimated quarterly taxes only if you expect to owe $1,000 or more in federal tax for the year (or $500 if you are self-employed). Checking account interest alone almost never reaches that threshold. Even $10,000 in interest, taxed at 22%, is $2,200 in tax, but that is only if interest is your only income and you have no withholding from wages.
If you have a job where taxes are withheld from your paycheck, that withholding usually covers the small amount of tax you owe on checking account interest. You do not need to do anything special — just report the interest when you file your annual return.
If you are self-employed or have other income without withholding, and your total tax liability is high, you may need to pay estimated taxes. But the checking account interest itself is not what triggers this requirement — your overall income situation does.
How to minimize tax on checking account interest
You cannot avoid paying tax on checking account interest, but you can be strategic about where you keep your money. If you have a large emergency fund or savings, a high-yield savings account earns more interest than a checking account, but the interest is still taxable. The difference is that you can shop for the highest rate available, which maximizes your after-tax return.
If you are in a high tax bracket and have substantial savings, a tax-advantaged account like a Roth IRA or 529 plan may make sense for some of your money. Interest earned inside these accounts is not taxed annually. But these accounts have contribution limits and rules about when you can withdraw the money, so they are not a substitute for a checking account.
For most people, the tax on checking account interest is small enough that it should not drive where you keep your money. A high-yield checking account that pays 4% and costs you $88 in tax is still better than a traditional account paying 0.01% and costing you $2 in tax.
Frequently Asked Questions
What if I earned less than $10 in interest — do I still have to report it?
Yes. The $10 threshold only determines whether the bank sends you a 1099-INT form. You still owe tax on any interest you earned, even if it is $1. You report it on Schedule 1 of your tax return. If you did not receive a 1099-INT, calculate the interest yourself from your statements.
Can I deduct anything to offset the tax on checking account interest?
No. Interest income is ordinary income, and there is no deduction tied to it. You report the full amount and pay tax at your marginal rate. You cannot reduce it by claiming a deduction unless you have other circumstances — like investment losses — that allow you to offset income generally.
Do I need to report interest from multiple banks separately?
No. Add up all the interest from all your accounts and report the total on one line of Schedule 1. The IRS receives copies of all your 1099-INT forms, so it already knows the total. Reporting the combined amount ensures your return matches.
What happens if I do not report the interest on my tax return?
The IRS receives a copy of your 1099-INT from the bank. If you do not report it, the IRS will notice the discrepancy and may send you a notice asking for the tax owed, plus penalties and interest. It is simpler to report it when you file.
Does interest earned in a joint checking account get split between owners for tax purposes?
The bank reports the full interest amount on a 1099-INT. How you and the other account owner split the tax liability is a matter between you — the IRS does not split it automatically. You and the other owner should decide who reports what, or you can each report a portion. Consult a tax professional if the amount is large.
