Interest on checking accounts counts as ordinary income on your tax return

Any interest your bank pays you on a checking account balance is taxable income. The IRS treats it the same way it treats wages or salary — you owe federal income tax on the full amount. Your bank will report this interest to you and to the IRS on a Form 1099-INT each January, and you report it on your tax return for that year.

The amount of interest you earn on a checking account is usually small — often less than $1 per year on a typical balance — but the rule applies regardless of the size. Even $0.50 in interest is technically taxable. Most people with checking accounts never owe additional tax because the interest is so minimal it falls well below the standard deduction, but you still need to report it if you file a return.

State income tax may also explore to checking account interest, depending on where you live. Some states tax all interest income; others exempt it or have different rules. Your state tax return instructions will tell you where to report it.

Key Takeaways

  • Banks report checking account interest to the IRS on Form 1099-INT, which you receive by January 31 of the following year.
  • You report this interest as ordinary income on your federal tax return, even if the amount is very small.
  • The interest is subject to federal income tax at your regular tax rate; there is no special lower rate for interest income.
  • State income tax rules on interest vary by state, so check your state's tax instructions to see if you owe state tax on the interest.
  • If your total interest income from all sources is below the standard deduction for your filing status, you may not owe tax, but you still report the income on your return.

When your bank sends you Form 1099-INT

Your bank will mail or email you a Form 1099-INT by January 31 if you earned $10 or more in interest during the previous calendar year. This form shows the total interest paid to your account. You receive one copy and the bank sends a copy to the IRS, so the IRS already knows about the interest before you file.

If you earned less than $10 in interest, the bank is not required to send you a 1099-INT, but the interest is still taxable. You still report it on your return if you file one. Some banks send a 1099-INT anyway even for small amounts, while others do not — either way, you are responsible for reporting the income.

Keep the 1099-INT with your tax records. The form shows the account number and the exact dollar amount of interest, which you will need when you fill out your tax return.

How to report checking account interest 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. Add up all interest from all sources — checking accounts, savings accounts, money market accounts, CDs, bonds, and any other interest-bearing accounts — and enter the total on that line.

The interest then flows to your Form 1040 as part of your total income. It is added to your wages, self-employment income, and any other income you have, and your tax is calculated on the combined total. There is no separate calculation or lower tax rate for interest — it is taxed at your regular income tax rate.

If you use tax software, it will usually walk you through entering the 1099-INT information. If you file by hand or with a tax professional, bring the 1099-INT with you so the preparer can enter it correctly.

Why the IRS tracks checking account interest

The IRS requires banks to report interest because interest income is income, and the agency wants to make sure people report all their income. When you earn interest, the bank is paying you money for the use of your funds — that is income in the eyes of the tax code, just like being paid for work.

The 1099-INT system is part of the IRS's information reporting program. The agency receives copies of all 1099-INTs filed by banks, so it can cross-check whether people reported the interest on their returns. If you receive a 1099-INT but do not report the interest, the IRS will likely notice the discrepancy.

This does not mean the IRS is auditing you — it is an automated matching process. But it is one reason to report all interest income, even small amounts: the IRS already knows about it.

Interest rates on checking accounts and what you actually earn

Most traditional checking accounts pay little to no interest. Many big banks pay 0.01% annual percentage yield (APY) or less, which means on a $1,000 balance you might earn $0.10 per year. High-yield checking accounts, usually offered by online banks or credit unions, may pay 4% to 5% APY, which would earn $40 to $50 per year on that same $1,000.

The interest you earn depends on three things: the account's APY, your account balance, and how long the money sits in the account. Even with a high-yield account, most people earn modest amounts of interest — often $10 to $100 per year unless they maintain a large balance.

Because the interest is usually small, the tax you owe on it is also small. If you earn $50 in interest and you are in the 22% federal tax bracket, you owe about $11 in federal income tax on that interest. But you still have to report it.

What happens if you do not report checking account interest

If you receive a 1099-INT and do not report the interest on your return, the IRS will eventually notice. The agency's computer system matches 1099s filed by banks against the income reported on tax returns. If there is a mismatch, you may receive a notice asking you to explain or pay the tax owed plus penalties and interest.

The penalty for not reporting income is usually 20% of the unpaid tax, plus interest that compounds daily. On a small amount like $50 in interest, the penalty might be $2 to $3, but it adds up if you ignore multiple years. It is much simpler to report the interest when you file.

If you file a return and straightforward forget to include the interest, you can file an amended return (Form 1040-X) to add it. The IRS is generally more lenient with honest mistakes than with unreported income, especially for small amounts.

Frequently Asked Questions

Do I have to file a tax return if I only earned interest on my checking account?

Not necessarily. You only have to file if your total income exceeds the standard deduction for your filing status. For 2024, the standard deduction is $14,600 for single filers and $29,200 for married filing jointly. If your only income is $50 in checking account interest, you do not have to file. However, if you have other income like wages, you must file and report the interest as part of your total income.

Can I deduct any expenses related to my checking account?

No. Interest income is reported as-is; you cannot deduct account fees, minimum balance penalties, or other costs against it. Those expenses are personal expenses and are not deductible on your federal tax return. You report the gross interest the bank paid you, with no offsets.

What if I earned interest in multiple checking accounts?

Add up all the interest from all your accounts and report the total on Schedule 1, line 8. Each bank will send you a separate 1099-INT if you earned $10 or more in that account, but you combine them all into one number on your return. Keep all the 1099-INTs with your records.

Is checking account interest taxed differently than savings account interest?

No. The IRS treats all interest income the same way, regardless of the account type. Checking account interest, savings account interest, money market interest, and CD interest are all reported on the same line of your return and taxed at your regular income tax rate.

Do I owe self-employment tax on checking account interest?

No. Self-employment tax applies only to income from self-employment or a business. Interest income is passive income and is not subject to self-employment tax. You owe only regular federal income tax (and state income tax if your state taxes interest).
