Yes, you owe federal income tax on checking account interest, and possibly state income tax too

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 investment returns — you have to report it on your tax return. Most banks pay very little interest on checking accounts right now, so your tax bill may be small or zero, but the obligation is real.

Your bank will send you a Form 1099-INT in January or February if you earned $10 or more in interest during the previous year. That form goes to both you and the IRS. You report the amount on your federal tax return, and the IRS cross-checks it against what your bank reported. If you earned less than $10, your bank may not send a form, but you still owe tax on the interest — you just have to track it yourself.

State income tax works the same way in most states. If your state has an income tax, you report the same interest income on your state return. A handful of states (including Illinois and Pennsylvania) do not tax interest income, so check your state's rules if you live there.

Key Takeaways

  • You must report all checking account interest on your federal tax return, even if the amount is small.
  • Your bank sends you Form 1099-INT if interest reaches $10 or more; amounts below $10 still count but you track them yourself.
  • Most states tax checking account interest the same way the federal government does, though a few states exempt it.
  • The interest rate on checking accounts is usually so low that the tax owed is minimal or rounds to zero.

How to find the interest amount your bank paid you

Log into your online banking portal or call your bank's customer service line. Ask for the total interest paid to your account during the tax year — January 1 through December 31. Your bank can tell you this number in minutes. You can also find it on your monthly statements by adding up the interest deposits, though that takes longer.

If you received a Form 1099-INT, the interest amount appears in Box 1 of that form. The form arrives by mail or email (depending on your bank's preference) by February 1 of the year after you earned the interest. Check the amount against your own records — banks make mistakes sometimes, and if the form is wrong, contact your bank to request a corrected form.

Where to report the interest on your tax return

On your federal return, you report checking account interest on Schedule 1, Line 2a (if you file Form 1040) or directly on Form 1040-SR if you are 65 or older. The interest goes into your total income, which means it can push you into a higher tax bracket if you are close to a threshold. For most people with checking account interest under $100, the effect is negligible.

If you use tax software (TurboTax, H&R Block, TaxAct, or similar), the software will ask you about interest income and put it in the right place automatically. If you file by hand or work with a tax preparer, bring your Form 1099-INT or your own record of the interest amount.

On your state return, follow your state's instructions for reporting interest income. Most state forms have a line for interest and dividends combined. Again, tax software usually handles this automatically once you enter the amount.

When the interest is so small you might owe nothing

If your checking account earned $50 in interest and you are in the 12% federal tax bracket, you owe roughly $6 in federal tax on that interest. If you are in the 22% bracket, you owe about $11. For many people, especially those with low balances or accounts that pay almost no interest, the tax owed rounds to zero — meaning your refund might be a few dollars larger, or you might owe a few dollars less.

You still have to report the interest, even if the tax is minimal. The IRS matches Form 1099-INT against your return, and if you leave it off, the IRS will send you a notice asking why. It is easier to report it correctly the first time.

High-yield checking accounts and higher interest amounts

Some banks and credit unions offer high-yield checking accounts that pay 4% to 5% annual interest on balances up to a certain amount (often $20,000 to $35,000). If you have money in one of these accounts, the interest can be substantial. A $25,000 balance at 5% interest earns $1,250 per year, which means roughly $275 in federal tax if you are in the 22% bracket, plus state tax.

High-yield checking accounts are still taxable income — there is no special tax break for them. But they are worth considering if you have cash sitting in a regular checking account earning 0.01% interest. Moving that money to a high-yield account means you pay more tax, but you also keep more money overall because the interest earned far exceeds the tax owed.

What happens if you do not report the interest

If your bank sends a Form 1099-INT to the IRS and you do not report the interest on your return, the IRS will notice the mismatch. You will receive a notice asking you to explain the discrepancy or pay the tax owed plus interest and penalties. The penalty is usually 20% of the unpaid tax, and interest accrues daily.

If the interest amount is small (under $100), the IRS may not pursue it aggressively, but the risk is still there. It is simpler and cheaper to report it correctly when you file. If you missed it in a prior year, you can file an amended return (Form 1040-X) to add the interest and pay any tax owed — the IRS will charge interest on the late payment, but you may avoid the penalty if you act before the IRS contacts you.

Frequently Asked Questions

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

Yes. Your bank does not have to send you a Form 1099-INT if interest is under $10, but you still owe tax on it. You track the amount yourself using your statements and report it on your return. The IRS does not know about it unless your bank reported it, so enforcement is unlikely, but the obligation is real.

What if I have multiple checking accounts at different banks?

Add up the interest from all accounts and report the total on your tax return. Each bank sends its own Form 1099-INT if that account earned $10 or more. If you have five accounts earning $3 each, you owe tax on $15 total, even though no single form was issued.

Can I deduct anything against the interest income?

No. Interest income is added to your total income with no deduction. You cannot offset it with other losses or expenses unless those expenses are investment-related (like fees paid to a financial advisor), and even then the rules are strict. For most people, checking account interest is simply added to income.

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

Not automatically. Whoever owns the account on the bank's records receives the Form 1099-INT. If you own the account jointly and want to split the tax burden, you and the other owner can agree to that privately, but the IRS sees only one person's name on the form. You may need to file an amended return or work it out when you file together if you are married filing jointly.

What if my bank paid interest but did not send a Form 1099-INT?

Contact your bank and ask for a corrected form. Banks are required to send one if interest reaches $10. If the bank refuses or says the amount was under $10, report the interest anyway based on your own records. Keep your statements as proof in case the IRS asks questions later.
