Checking account interest is taxable income

Yes. Any interest your bank pays you on a checking account balance is taxable income that you must report to the IRS. The bank treats it the same way it treats wages or freelance income — money that came to you, and therefore money you owe tax on.

The amount is usually small. Most checking accounts earn between 0.01% and 5% annual interest, depending on the bank and the account type. On a $10,000 balance at 0.5% interest, you would earn $50 per year. On a $10,000 balance at 4.5% interest, you would earn $450 per year. But small or large, the IRS wants to know about it.

Your bank will send you a form called a 1099-INT (Interest Income) if the interest you earned reaches a certain threshold. For most banks, that threshold is $10 in a calendar year. If you earned less than $10, the bank does not have to send you a form, but you still owe tax on it.

Key Takeaways

  • All checking account interest is taxable income, even if your bank does not send you a 1099-INT form.
  • Your bank will mail or email you a 1099-INT if you earned $10 or more in interest during the year.
  • You report checking account interest on your tax return using Schedule B (Form 1040) or by entering it directly on your return, depending on your total interest income.
  • The interest is taxed at your ordinary income tax rate, which varies based on your total income and filing status.
  • If your bank sends you a 1099-INT with an incorrect amount, you can correct it by contacting the bank and filing an amended return if needed.

When your bank sends you a 1099-INT

Banks are required to send you a 1099-INT if you earned $10 or more in interest during the calendar year. You will receive it by January 31 of the following year. The form shows the total interest paid to you in the previous year, broken down by account if you have multiple accounts at the same bank.

The bank sends a copy to you and a copy to the IRS. This is how the IRS knows to expect that income on your tax return. If you do not report it, the IRS will notice the mismatch and may contact you.

Some banks offer high-yield checking accounts that pay significantly more interest than traditional accounts. If you have one of these, you are more likely to cross the $10 threshold and receive a 1099-INT. Online banks and credit unions often pay higher rates than brick-and-mortar banks.

How to report checking account interest on your tax return

The way you report the interest depends on how much total interest income you have. If your total interest income from all sources (checking, savings, money market accounts, bonds, CDs) is $1,500 or less, you can report it directly on line 2b of Form 1040 (the main federal tax form). You do not need to file Schedule B.

If your total interest income is more than $1,500, you must use Schedule B (Form 1040), which is a separate worksheet you attach to your return. Schedule B asks you to list each source of interest income separately. You then transfer the total to your Form 1040.

If you file your taxes using tax software, the software will guide you through this process. You enter the amount from your 1099-INT, and the software places it in the correct location on your return. If you file by hand or work with a tax preparer, bring your 1099-INT with you.

What tax rate applies to your interest income

Checking account interest is taxed at your ordinary income tax rate, not at a special rate. This means it is added to all your other income for the year, and you pay tax on the combined total at whatever rate applies to your income bracket.

If you earn $50,000 per year and your checking account interest is $100, your taxable income becomes $50,100. The $100 is taxed at the same rate as the rest of your income. For 2024, if you are single and earn between $47,150 and $100,525, your federal tax rate is 22% on income in that range. So the $100 in interest would cost you roughly $22 in federal tax (before any deductions or credits).

State income tax also applies to checking account interest in most states. The rate varies by state. Some states do not tax interest income at all, while others tax it at the same rate as wages. Check your state's tax authority website to learn what applies to you.

Interest earned before you receive the 1099-INT

You owe tax on interest the moment it is credited to your account, even if you have not received the 1099-INT yet. The 1099-INT is just documentation — it does not create the tax obligation. The obligation exists as soon as the bank pays you the interest.

This matters if you are filing your return before January 31 and you know how much interest you earned. You can contact your bank and ask for the interest total, or you can log into your online banking and add up the interest deposits yourself. Then report that amount on your return, even if the 1099-INT has not arrived yet.

If you report the interest on your return and the 1099-INT arrives later with a different amount, you may need to file an amended return. This is rare, but it can happen if the bank made an error or if interest was credited after you filed.

What to do if the 1099-INT amount is wrong

If your 1099-INT shows an amount that does not match what you earned, contact your bank first. Banks make mistakes — they may have credited interest to the wrong account, double-counted a deposit, or included interest from an account you closed. Ask the bank to review the calculation and send you a corrected 1099-INT if needed.

The bank will issue a corrected form (marked as a "corrected" 1099-INT) and send it to you and the IRS. You do not need to do anything else — the IRS will see the correction and update their records.

If the bank refuses to correct it or you disagree with their explanation, you can file an amended return (Form 1040-X) showing the correct amount of interest. Attach a note explaining the discrepancy. Keep records of your bank statements showing the actual interest deposits so you can prove your number if the IRS questions it.

Checking accounts that do not pay interest

Many traditional checking accounts pay no interest at all, or interest so small that it rounds to zero. If your account earned less than $1 in interest during the year, you still technically owe tax on it, but the amount is negligible. Your bank will not send you a 1099-INT, and the IRS is not going to pursue you over pennies.

However, if you want to be thorough, you can report even tiny amounts on your return. Some tax software allows you to enter interest income of less than $1. If you do, you are being fully compliant, though it is not required.

Frequently Asked Questions

Do I have to report checking account interest if I earned less than $10?

Technically yes, but your bank will not send you a 1099-INT. The IRS expects you to report all income, including small amounts. In practice, the IRS does not pursue people over interest income under $10. If you want to be fully compliant, you can report it; if you do not, enforcement is unlikely.

Can I deduct fees my bank charged against the interest I earned?

No. You report the gross interest your bank paid you, not the net after fees. Bank fees are not deductible on your personal tax return. However, if you are self-employed and use a business checking account, business bank fees may be deductible as a business expense.

What if I moved money between checking accounts during the year?

The interest is taxable no matter which account it was credited to or how many times you moved the money. Report the total interest shown on your 1099-INT. If you have accounts at multiple banks, each bank sends its own 1099-INT, and you report all of them.

Does checking account interest count toward my standard deduction?

No. The standard deduction is a fixed amount that reduces your taxable income. Interest income does not affect it. You get the standard deduction regardless of whether you earned $0 or $500 in interest. The interest is added to your other income, and then the standard deduction is subtracted from the total.

What if my bank is outside the United States?

You still owe U.S. tax on the interest. Foreign banks are not required to send you a 1099-INT, but you are required to report the income. Keep records of the interest deposits and report them on your return. If you have foreign financial accounts, you may also need to file additional forms (FBAR or FATCA) depending on the account balance.
