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 requires you to report it on your tax return, even if the amount is small. Your bank will send you a form called a 1099-INT (Interest Income) if you earned $10 or more in interest during the year, but you may owe taxes on interest below that threshold too.
The reason is straightforward: interest is money the bank paid you for letting them use your deposit. From the IRS perspective, it is income just like wages or a paycheck. You do not get to choose whether to report it based on the amount.
Key Takeaways
- You must report all checking account interest on your federal tax return, regardless of the amount.
- Banks send a 1099-INT form only if interest reaches $10 or more, but you still owe taxes on smaller amounts.
- Interest income goes on your Form 1040 or 1040-SR, usually on Schedule 1 or directly on the main form depending on your filing method.
- Most checking accounts earn very little interest, so the tax impact is usually minimal, but the reporting requirement remains the same.
When your bank sends you a 1099-INT form
Your bank will mail or email you a 1099-INT by January 31 of the year after you earned the interest. This form shows how much interest you received during the previous calendar year. You will receive one form per bank account if you have multiple accounts at the same institution, or separate forms if you bank at different places.
The 1099-INT comes in triplicate: one copy for you to keep, one for the IRS, and one for your state tax authority (if your state has income tax). The IRS receives their copy automatically, so they will know about your interest income whether you report it or not.
If you earned less than $10 in interest, your bank may not send a 1099-INT at all. However, you still owe taxes on that interest. You will need to add it to your return based on your own records—check your monthly statements or your online banking history.
How to report interest on your tax return
Where you report the interest depends on which form you file. If you use Form 1040 (the standard individual income tax return), interest income typically goes on Schedule 1 (Additional Income and Adjustments to Income), line 8. You then transfer the total to your main Form 1040.
If you file Form 1040-SR (for people 65 and older), interest income goes directly on the main form itself, not on a separate schedule. The specific line number may vary depending on the year, so check the current form instructions.
When you report the interest, use the amount from your 1099-INT if you received one. If you did not receive a form because the interest was under $10, add up the interest from your bank statements yourself and enter that total. Keep your statements or a record of how you calculated it in case the IRS asks.
Why most checking account interest is negligible
Most traditional checking accounts earn little to no interest. Banks that do pay interest on checking accounts typically offer rates well below 1 percent per year. If you have $1,000 in a checking account earning 0.01 percent annually, you would earn about 10 cents—below the $10 threshold for a 1099-INT.
Some online banks and credit unions offer higher rates on checking accounts, sometimes 4 percent or more, but these are less common. Even at a higher rate, the actual dollar amount depends on your balance. A $5,000 balance at 4 percent earns $200 per year, which you would report.
The point is not that the tax burden is heavy—it usually is not—but that the reporting requirement exists regardless. You cannot skip reporting because the amount is small.
The difference between checking and savings account interest
Interest from a savings account follows the same reporting rules as checking account interest. Both appear on a 1099-INT and both must be reported on your tax return. The only difference is where the money sits: checking accounts are meant for spending, while savings accounts are meant for storing money longer.
Some accounts blur this line. A money market account, for example, works like a savings account but may have check-writing privileges. Interest from a money market account is still reported the same way—on a 1099-INT and on your tax return.
What happens if you do not report the interest
The IRS receives a copy of every 1099-INT your bank sends. If you do not report the interest on your return, the IRS will notice the mismatch between what you reported and what the bank reported. This can trigger a notice asking you to explain the discrepancy.
In most cases, if the amount is small and you straightforward forgot, you can file an amended return (Form 1040-X) and pay any taxes owed plus a small penalty. If the IRS suspects intentional underreporting, the penalties are steeper. It is far simpler to report the interest in the first place, even if the amount is tiny.
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 still owe taxes on all interest, no matter how small. Track it yourself from your bank statements and report it on your return.
What if I have interest from multiple banks?
Add up all the interest from all your accounts and report the total on one line of your tax return. You will receive a separate 1099-INT from each bank, but you combine them into a single entry when you file.
Can I deduct anything against the interest income?
No. Interest income is reported as-is; you cannot deduct expenses or fees against it. However, if you paid investment fees or had other miscellaneous deductions, those follow different rules and go on different parts of your return.
Does state income tax explore to checking account interest too?
Most states that have income tax require you to report interest income on your state return as well. A few states do not tax interest income, but you should check your state's rules. Your state will receive a copy of the 1099-INT from your bank.
What if my bank made an error on the 1099-INT?
Contact your bank and ask them to issue a corrected form (called an amended 1099-INT). Once they send the corrected version, you may need to file an amended federal return if the error changed your tax liability. Keep documentation of the correction in case the IRS asks.
