Yes, you must report checking account interest on your taxes, but only if it reaches a certain threshold

Any interest your bank pays you on a checking account is taxable income. The IRS expects you to report it. However, the bank only sends you a formal notice if the interest reaches $10 or more in a calendar year. If your account earned less than $10, you still owe tax on it — the bank just won't document it for you.

This matters because even small amounts add up across multiple accounts. If you have checking accounts at two banks and each earned $8 in interest, you owe tax on the full $16, even though neither bank reported it to the IRS.

Key Takeaways

  • You must report all checking account interest on your tax return, regardless of the amount.
  • Banks send a Form 1099-INT only when interest reaches $10 or more in a single year.
  • Interest under $10 still counts as taxable income and should be added to your other interest income.
  • Keep your own records of interest earned if the bank does not send you a form.
  • The interest is taxed at your ordinary income tax rate, not a special rate.

When the bank sends you a Form 1099-INT

If your checking account interest totals $10 or more during the calendar year, your bank will mail you a Form 1099-INT by January 31 of the following year. This form shows the interest amount in Box 1. The bank sends a copy to the IRS at the same time, so the IRS already knows about this income.

The $10 threshold is a reporting requirement, not a tax threshold. The IRS does not care whether the bank reported it — you owe tax on every dollar of interest your account earned.

Interest under $10 that you must still report

If your checking account earned less than $10 in interest, the bank will not send you a Form 1099-INT. You will not receive any official document. This does not mean the interest is tax-free — it means you are responsible for tracking it yourself.

Write down the interest your bank paid you each month. You can find this on your monthly statement or by logging into your online banking. Add up the total for the year and report it on your tax return, even if no form arrives.

Many people with multiple accounts at different banks have this situation. One account earns $7, another earns $6, and a third earns $4. The bank reports none of them, but you owe tax on all $17.

How to report interest on your tax return

Interest income goes on Schedule B (Interest and Ordinary Dividends) if you file Form 1040. On Schedule B, you list each source of interest and the amount. If you have a Form 1099-INT, copy the amount from Box 1. If you do not have a form, write in the amount you calculated from your statements.

The total from Schedule B carries forward to your main tax return (Form 1040, line 1b). This interest is added to your wages, self-employment income, and any other income you earned that year. It is taxed at your ordinary income tax rate — the same rate as your salary.

If you use tax software, it will usually ask you to enter interest income and handle the rest. If you file by hand or work with a tax preparer, bring your Form 1099-INT or your own record of the interest amount.

Why banks have a $10 threshold

The $10 rule exists because the IRS decided the paperwork burden of reporting tiny amounts was not worth the effort. It is an administrative convenience, not a tax break. The threshold has not changed since 1986, so it has lost meaning over time — $10 then is worth roughly $30 today.

Some banks pay higher interest rates on checking accounts than others, especially online banks and credit unions. If you keep a large balance or have multiple accounts, you could easily cross the $10 threshold even with modest rates.

What to do if you lost your Form 1099-INT

If your bank sent you a Form 1099-INT but you cannot find it, contact the bank and ask for a duplicate. Most banks can reissue it quickly. You can also call the IRS at 800-829-1040 and ask them to send you a copy — they have a record because the bank filed it with them.

Do not guess at the amount. Use the official form or your bank statement to confirm the exact interest paid. If the amount on your tax return does not match what the IRS received from the bank, you may receive a notice asking you to explain the difference.

Interest from savings accounts and money market accounts

The same $10 reporting rule applies to savings accounts, money market accounts, and certificates of deposit (CDs). Any interest-bearing account generates taxable income. If you have interest from multiple account types at the same bank, the bank adds them together to decide whether to send a Form 1099-INT.

For example, if your checking account earned $6 and your savings account earned $5 at the same bank, the bank will not send a form because the total is $11 — wait, that is above $10. Actually, the bank will send a form because the combined interest is $11. The point is that the bank looks at all your accounts with them together, not each account separately.

Frequently Asked Questions

What if I earned interest but the bank closed my account?

The bank still owes you the interest and will still report it if it reaches $10. You may receive the Form 1099-INT at your last known address on file. If you do not receive it, contact the bank with your account number and ask them to send it or confirm the amount so you can report it yourself.

Do I have to report interest if I am not filing a tax return?

If you are required to file a tax return based on your income, you must report the interest. Whether you are required to file depends on your age, filing status, and total income — not on whether you received a form. Consult the IRS website or a tax preparer to confirm whether you must file.

Can I deduct bank fees against the interest I earned?

No. You report the full interest amount as income. Bank fees are not deductible on your personal tax return. You report interest and fees separately — interest as income and fees as a cost of maintaining the account, which generally cannot be deducted.

What if the bank reported the wrong amount on my Form 1099-INT?

Contact the bank when ready and ask them to issue a corrected form (Form 1099-INT with a "CORRECTED" box marked). The bank will send the corrected version to you and the IRS. Report the corrected amount on your tax return. Keep both the original and corrected forms for your records.

Is interest from a joint checking account split between owners for tax purposes?

No. The person whose Social Security number is on file with the bank receives the Form 1099-INT for the full amount. That person reports all the interest, even if the account is jointly owned. If you and a co-owner want to split the tax burden, you will need to work that out between yourselves — the IRS does not split it automatically.
