Yes, you report checking account interest on your tax return if you earned any

The IRS requires you to report all interest income, including interest earned on checking accounts. If your bank paid you interest during the year, that amount goes on your federal tax return. The threshold is low: you must report interest income even if it is only a few dollars.

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. If you earned less than $10, the bank is not required to send the form, but you still owe tax on that interest. You report it anyway.

The interest is taxed as ordinary income at your regular tax rate, not at a special rate. This means a few dollars in checking account interest could push you into a higher tax bracket, though in practice the effect is usually small.

Key Takeaways

  • Report all checking account interest on your federal tax return, even amounts under $10 that your bank does not report to the IRS.
  • Your bank sends Form 1099-INT if you earned $10 or more in interest during the year, usually by early February.
  • Interest income is taxed at your ordinary income tax rate, not a preferential rate.
  • If you did not receive a 1099-INT but earned interest, you still report it on Schedule 1 (Form 1040) or the interest income line on your return.
  • Some states also tax interest income, so check your state tax rules separately.

Where the interest goes on your return

On your federal return, interest income appears on Schedule 1 (Form 1040), line 8, labeled "Interest." If you file the short form (1040-SR or 1040-EZ if you still use it), there is usually a line for interest income on the main form itself.

If you have a 1099-INT, copy the amount from box 1 of that form. If you earned interest but did not receive a 1099-INT because the amount was under $10, write in the amount you know you earned. Your bank statement or online account history will show the interest deposits.

If you have multiple accounts at different banks, add all the interest together and report the total. You do not file separate forms for each account.

What happens if you do not report it

The IRS receives a copy of every 1099-INT your bank files. If you do not report interest that appears on a 1099-INT, the IRS will notice the discrepancy. The agency matches third-party documents (like 1099s) to tax returns automatically.

Failing to report interest can result in penalties and interest charges on the unpaid tax. The penalty for negligence is usually 20 percent of the underpaid tax. If the IRS determines the omission was intentional, the penalty can be higher. You will also owe back taxes plus interest calculated from the original due date.

If you earned interest under $10 and did not receive a 1099-INT, the risk of detection is lower, but you are still legally required to report it. The safest approach is to report all interest, no matter the amount.

Interest from high-yield savings and money market accounts

The same rule applies to interest from savings accounts, money market accounts, and certificates of deposit (CDs). Any account that earns interest—whether at a traditional bank, online bank, or credit union—generates reportable income.

High-yield savings accounts often pay significantly more interest than traditional checking accounts. A $10,000 balance in a high-yield account earning 4 or 5 percent annually will generate $400 to $500 in interest, which is substantial enough that you will definitely receive a 1099-INT.

If you have accounts at multiple banks or credit unions, each institution sends its own 1099-INT. You add all the interest together on your return.

State taxes on interest income

Most states that have an income tax also tax interest income. The rules vary by state. Some states exempt a small amount of interest income for residents over a certain age, but most do not.

You will report the same interest amount on your state return as you do on your federal return. Some states use the federal amount as a starting point; others require you to list it separately. Check your state's tax instructions or contact your state revenue department to confirm the rule in your state.

A few states (like Florida, Texas, and Tennessee) do not have an income tax at all, so you owe no state tax on interest. If you moved during the year or earned interest in multiple states, the rules become more complex and you may need to file returns in more than one state.

Reporting interest when you are a dependent

If you are claimed as a dependent on someone else's return, you still report your own interest income. Your parents or guardians do not report your interest on their return; you report it on yours.

If your interest income is your only income and it falls below the standard deduction for dependents (which is higher than for independent filers), you may not owe tax. However, you may still need to file a return to report the interest. The rules depend on your age and the type of income.

Check the IRS instructions for dependents or use the IRS interactive tool to determine whether you must file. When in doubt, filing is safer than not filing.

Frequently Asked Questions

Do I report interest if I earned less than $10?

Yes. The $10 threshold only determines whether your bank must send you a 1099-INT. You are required to report all interest income, regardless of amount. If you earned $3 in interest, you report it.

What if my bank sent me a 1099-INT but the amount is wrong?

Contact your bank when ready and ask them to issue a corrected 1099-INT (marked as a correction). Once corrected, the bank will send a corrected form to you and to the IRS. Report the corrected amount on your return. Keep documentation of the correction in case the IRS questions the discrepancy.

Can I deduct expenses to earn checking account interest?

No. Interest income is reported as-is; you cannot deduct fees, minimum balance requirements, or other costs associated with the account. Those are personal expenses, not investment expenses.

Do I report interest from a joint account differently?

If the account is jointly owned, the bank typically reports the full interest amount on a single 1099-INT. You and the other owner must decide how to split the income for tax purposes. Many couples split it 50-50, but the split should match how you actually own the account. Keep records of your agreement in case the IRS asks.

What if I closed my account mid-year and earned interest before closing?

Report all interest earned during the year, even if you closed the account in December. The bank will report it on a 1099-INT for that year. The closing of the account does not change your reporting obligation.
