Yes, you must report checking account interest as income on your federal tax return
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, regardless of how small it is.
Your bank will send you a Form 1099-INT in January or early February if you earned $10 or more in interest during the previous year. This form lists the total interest paid to you. Even if you don't receive a 1099-INT because your interest was under $10, you still owe tax on whatever you earned — you just have to track it yourself and report it.
The tax you owe depends on your overall income and tax bracket. Interest income is added to your other income (wages, self-employment, investment gains) and taxed at your ordinary income rate, which can range from 10% to 37% depending on how much you earn.
Key Takeaways
- All checking account interest must be reported on your federal tax return, even amounts under $10.
- Your bank sends Form 1099-INT if you earned $10 or more in interest during the year.
- Interest is taxed as ordinary income at your marginal tax rate, not at a special rate.
- You report the interest on Schedule 1 (Form 1040) or directly on Form 1040 depending on your filing method.
- State and local taxes may also explore to checking account interest in some states.
How the 1099-INT form works and what it tells you
The 1099-INT arrives in the mail or electronically if your bank has your email on file. It shows the total interest paid to your account during the calendar year. Box 1 on the form contains the figure you need — that is the amount you report to the IRS.
You receive one 1099-INT per account at each institution. If you have multiple checking accounts at different banks, each bank sends its own form. If you have multiple accounts at the same bank, they may combine the interest on a single form or send separate forms depending on how the accounts are registered.
Keep your 1099-INT with your tax records. You do not send it to the IRS with your return, but you need it to fill out your tax forms correctly, and you should keep it for at least three years in case of an audit.
Where checking account interest appears on your tax return
If you file Form 1040 (the standard federal income tax form), you report interest income on Schedule 1, Part I, Line 8. This is where all your interest income goes — checking, savings, bonds, and any other sources combined.
The total from Schedule 1 transfers to your Form 1040, where it becomes part of your total income. From there, the IRS calculates your tax liability based on your tax bracket and any deductions or credits you claim.
If you use tax software, the program typically walks you through entering the 1099-INT information and places it in the correct location automatically. If you file by hand or work with a tax preparer, they will handle the placement.
When the interest is so small you might not receive a 1099-INT
Banks are required to send a 1099-INT only if interest reaches $10 or more in a calendar year. If your checking account earned $8 in interest, your bank will not send you a form. You are still responsible for reporting that $8 on your tax return.
To find out how much interest you earned below the $10 threshold, check your account statements or log into your online banking portal. Most banks show interest deposits monthly or quarterly. Add them up for the full year and report the total on Schedule 1, Line 8, even though you have no 1099-INT to reference.
The IRS knows banks are not sending 1099-INTs for amounts under $10, so reporting interest you earned without a form is normal and expected. Keep your bank statements as proof in case you are audited.
State and local taxes on checking account interest
Federal tax is not the only tax that applies. Many states tax interest income at their state income tax rate. A few states do not tax interest at all — currently, Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax.
If you live in a state with income tax, you will report the same interest amount on your state return. Some states use the federal 1099-INT directly; others require you to enter the information manually. Your state tax form will specify where interest goes.
Some cities also tax income, including interest. New York City and Columbus, Ohio are examples. If you live in a city with an income tax, check your local tax form to see whether interest is taxable at the local level.
How much tax you actually owe on checking account interest
The tax rate on interest depends on your total income for the year. Interest is not taxed at a flat rate — it is added to your other income and taxed at your marginal tax rate, which is the rate that applies to your highest dollar of income.
If you earn $50,000 in wages and $200 in checking account interest, that $200 is taxed at whatever rate applies to income between $50,000 and $50,200. For a single filer in 2024, that is the 22% bracket. For someone earning $500,000, the same $200 in interest would be taxed at 37%.
This is why the actual tax you owe on interest varies so widely. A person in the 10% bracket pays $20 in tax on $200 of interest. A person in the 37% bracket pays $74 on the same $200. Your bank does not withhold tax on interest — you owe it when you file your return.
What happens if you do not report checking account interest
The IRS receives a copy of every 1099-INT that banks send. If you earn $10 or more in interest and do not report it, the IRS will notice the discrepancy between what you reported and what the bank reported. This triggers a notice asking you to explain the difference or pay the tax owed plus penalties and interest.
If your interest was under $10 and you did not report it, the IRS is less likely to catch it because no 1099-INT exists in their system. However, if you are audited for other reasons, the auditor may review your bank statements and find unreported interest. The penalty for failing to report income is typically 20% of the unpaid tax, plus interest calculated from the original due date.
Reporting the interest takes minutes and costs nothing. Not reporting it creates a liability that compounds over time.
Frequently Asked Questions
What if I earned interest in a joint checking account — do both owners report it?
The bank sends one 1099-INT to the account owner of record (usually the person whose Social Security number is listed first on the account). That person reports the full amount. If you and a co-owner want to split the tax burden, you can file an amended return and report only your share, but the IRS will not automatically split it — you have to handle it yourself.
Do I report interest from a checking account held in a trust or estate?
Interest from a trust or estate account is reported on the trust or estate's tax return (Form 1041), not on your personal return. The trustee or executor handles this reporting. You would not include it on your individual Form 1040.
Can I deduct any expenses related to my checking account against the interest income?
No. Interest income is reported in full, and you cannot deduct account fees, minimum balance penalties, or other banking costs against it. Those expenses are not deductible on your personal tax return.
What if my bank made an error on the 1099-INT and reported the wrong amount?
Contact your bank and ask them to issue a corrected 1099-INT (marked as a correction). Once you receive the corrected form, report the correct amount on your tax return. If you already filed with the wrong amount, you can file an amended return (Form 1040-X) with the correct figure.
Does interest earned in a high-yield checking account get reported differently?
No. Whether the interest comes from a standard checking account or a high-yield checking account, it is all reported the same way on Form 1099-INT and Schedule 1. The rate does not matter — only the total amount earned.
