Checking account interest counts as taxable income

Any interest your checking account earns is taxable income to the IRS. You report it on your federal tax return the same way you report wages or other money that comes in. The bank sends you a form at the end of the year, you add the amount to your tax return, and you owe federal income tax on it at your regular rate.

The amount of tax you pay depends on how much interest you earned and what tax bracket you fall into. If you earned $50 in interest and you're in the 22% tax bracket, you owe roughly $11 in federal tax on that interest. State income tax applies too in most states.

This applies whether your checking account is at a traditional bank, an online bank, or a credit union. The only exception is if you earned so little interest that you fall below the reporting threshold — but you still owe tax on it even if you don't have to report it.

Key Takeaways

  • Banks report checking account interest to the IRS on Form 1099-INT, which you receive by January 31 each year.
  • You report this interest on your federal tax return as ordinary income and pay tax at your regular income tax rate.
  • If you earned less than $10 in interest, the bank may not send you a 1099-INT, but you still owe tax on the amount you earned.
  • High-yield checking accounts earn more interest than traditional accounts, which means higher tax liability on that interest.
  • State income tax applies to checking account interest in most states, in addition to federal tax.

When the bank sends you the interest report

Your bank sends you Form 1099-INT by January 31 of the year after you earned the interest. This form shows exactly how much interest you made during the previous calendar year. You receive a copy and the IRS receives a copy at the same time.

If you earned less than $10 in interest during the year, the bank may not send you a 1099-INT at all. However, you are still required to report that interest on your tax return. Many people miss this because they assume no form means no reporting requirement.

If you have accounts at multiple banks or credit unions, you'll receive a separate 1099-INT from each institution. Add all the interest amounts together when you file your return.

How to report the interest on your tax return

When you file your federal return, you report the interest income on Schedule 1 (Form 1040) under "Interest." If you use tax software, it will ask you for this amount and place it in the right spot automatically. If you file by hand, write the total interest from all your 1099-INT forms on the line for interest income.

This interest gets added to your other income for the year. If you earned $50,000 in wages and $200 in checking account interest, your taxable income is $50,200. You then pay tax on the full amount at your regular rate.

You don't need to attach the 1099-INT to your return, but keep it with your tax records for at least three years in case the IRS asks questions.

The difference between high-yield and traditional checking accounts

A traditional checking account at a big bank might earn 0.01% annual interest or less. A high-yield checking account at an online bank might earn 4% to 5% or higher. The higher the interest rate, the more interest you earn — and the more you owe in taxes.

If you keep $10,000 in a traditional account earning 0.01%, you earn $1 per year in interest and owe roughly $0.22 in federal tax (at the 22% bracket). If you keep the same $10,000 in a high-yield account earning 4.5%, you earn $450 per year and owe roughly $99 in federal tax. The tax liability is real and worth factoring in when you choose where to keep your money.

This doesn't mean high-yield accounts are a bad choice — the interest you earn still goes into your pocket. But it's worth knowing that the higher rate comes with a higher tax bill.

State income tax on checking account interest

Most states tax interest income the same way the federal government does. You report it as ordinary income and pay tax at your state rate. A few states don't have income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming), so residents of those states owe federal tax only.

If you live in a state with income tax, your state tax bill on checking account interest depends on your state's tax bracket. Some states have flat tax rates; others have brackets like the federal system. Check your state's tax authority website or your state tax return instructions to see where interest income goes.

If you moved during the year or earned interest in multiple states, the reporting gets more complex. Your 1099-INT shows the total interest, but you may need to allocate it between states based on where you lived when you earned it.

What to do if you didn't receive a 1099-INT

If you earned interest but didn't receive a 1099-INT by early February, contact your bank directly. Ask them to send you a copy or confirm the amount you earned. Keep a record of this communication.

If the bank confirms you earned interest but says they didn't send a form because the amount was under $10, you still need to report it. Write down the amount from your account statements and include it on your tax return under interest income.

If you can't reach the bank or they have no record of sending a form, you can still file your return using the interest amount from your own account statements. The IRS has your copy of the 1099-INT, so they know what you earned even if you didn't receive your copy.

How interest affects your overall tax situation

Checking account interest is ordinary income, which means it gets taxed at your regular income tax rate. It doesn't get special treatment like long-term capital gains or may have access to dividends do. If you're in the 24% federal tax bracket, you pay 24% tax on the interest.

If you're close to a tax bracket boundary, the interest might push you into a higher bracket. For example, if your income is $89,000 and you're in the 22% bracket, but you earn $2,000 in checking account interest, your new income is $91,000, which might move you into the 24% bracket for part of your income.

For most people with modest checking account balances, the tax impact is small. But if you have a large balance in a high-yield account, it's worth running the numbers to see how much tax you'll owe before the year ends.

Frequently Asked Questions

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

Yes. The bank doesn't have to send you a 1099-INT for amounts under $10, but you still owe tax on whatever you earned. Look at your account statements, add up the interest, and report it on your return.

Can I deduct anything to offset the tax on checking account interest?

No. Interest income is ordinary income with no deductions tied to it. You can't reduce it by claiming expenses or losses related to the account. You pay tax on the full amount you earned.

What if my bank made a mistake on the 1099-INT?

Contact the bank and ask them to issue a corrected form (Form 1099-INT with a "Corrected" box checked). Once you receive it, file an amended return if you already filed. Keep records of your communication with the bank.

Does interest from a joint checking account get split between account holders for tax purposes?

Not automatically. The bank reports the full interest amount on a single 1099-INT. You and the other account holder need to decide how to split the tax liability — usually based on each person's ownership stake — and report your share on your individual returns. Discuss this with the other account holder before tax time.

Is checking account interest taxed differently if I'm retired?

No. Interest is taxed the same way regardless of your age or employment status. However, if you're over 65, you may have a higher standard deduction, which could reduce your overall tax liability. The interest itself is still taxed at your regular rate.
