You don't pay income tax on the money sitting in your checking account itself, but you do pay tax on the interest your bank pays you

The balance you keep in checking — whether it's $500 or $50,000 — is not taxable income. That money is yours, and you've already paid tax on it when you earned it. The IRS doesn't tax you again for holding it.

What is taxable is the interest your bank pays you for keeping money there. If your checking account earns interest (many do not, but some high-yield accounts do), that interest counts as income and you owe federal income tax on it. Some states also tax this interest income.

The amount of interest is usually small — often less than $1 per year on a regular checking account — but the rule applies no matter the size. Your bank will send you a Form 1099-INT each January if you earned $10 or more in interest during the previous year, and you report that amount on your tax return.

Key Takeaways

  • Money in your checking account is not taxable income, even if you have a large balance.
  • Interest paid by your bank on a checking account is taxable income and must be reported to the IRS.
  • Your bank sends Form 1099-INT if you earned $10 or more in interest during the year.
  • High-yield checking accounts pay more interest than traditional accounts, which means more tax owed on that interest.
  • State income tax rules on interest vary — some states tax it, others do not.

How banks report interest income to the IRS

Your bank tracks all interest paid to your account during the calendar year. In late January or early February, they mail or email you a Form 1099-INT showing the total. This form goes to the IRS at the same time, so the agency knows what interest you received.

You then report this interest on your federal tax return. If you file Form 1040, the interest goes on Schedule 1, line 8 (or the equivalent line if you use tax software). The IRS matches what you report against what the bank reported, so underreporting or omitting it can trigger a notice.

If you earned less than $10 in interest, your bank may not send a 1099-INT, but you still owe tax on that interest if you file a return. Keep your bank statements as proof of what you earned.

The difference between regular and high-yield checking accounts

A traditional checking account at most banks pays zero interest or a rate so low it rounds to nothing — often 0.01% annually. On a $5,000 balance, that's about 50 cents per year.

A high-yield checking account, usually offered by online banks or credit unions, pays significantly more — sometimes 4% to 5% annually, depending on the institution and current market rates. On the same $5,000, that could be $200 to $250 per year. All of that interest is taxable income.

If you're considering moving to a high-yield account for the interest, factor in the tax cost. If you earn $200 in interest and you're in the 22% federal tax bracket, you'll owe roughly $44 in federal tax on that interest (plus any state tax). The interest is still worth it in most cases, but it's not $200 in your pocket — it's $200 minus taxes.

State taxes on checking account interest

Federal income tax applies everywhere, but state rules vary. Most states that have an income tax also tax interest income the same way the IRS does. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax at all, so you owe nothing to the state on checking account interest.

If you live in a state with income tax, check your state's tax agency website or ask your tax preparer whether interest is taxable at the state level. The rate and rules may differ from federal tax.

Some states offer tax-exempt savings accounts or other special accounts, but these are rare for checking accounts. Most checking account interest is taxable at both federal and state levels if you live in a state with income tax.

What happens if you don't report checking account interest

The IRS receives a copy of every 1099-INT your bank sends. If you don't report the interest on your return, the IRS will likely notice the discrepancy. You may receive a notice asking you to explain the difference or pay the tax owed plus penalties and interest.

The penalty for underreporting income is typically 20% of the underpaid tax, plus interest that accrues daily. On a small amount like $50 in unreported interest, the penalty might be $10 plus interest, but it adds up if you ignore multiple years.

If the IRS suspects intentional fraud rather than an honest mistake, penalties can be much higher — up to 75% of the underpaid tax. For checking account interest, most cases are treated as mistakes, but reporting it correctly from the start avoids the problem entirely.

How to handle interest if you have multiple accounts

If you have checking accounts at more than one bank, each one sends a separate 1099-INT if you earned $10 or more at that institution. You report the interest from each form on your tax return, and the total is what you owe tax on.

Some tax software and tax preparers can import 1099 forms directly, which reduces the chance of missing one. If you prepare your own return, keep all 1099-INT forms together and add up the totals before entering them on your return.

If one account earned $8 in interest and another earned $7, neither bank sends a 1099-INT, but you still owe tax on the combined $15. Track this yourself using your bank statements.

Interest on joint checking accounts and tax responsibility

If you have a joint checking account with another person, the interest earned belongs to both account holders. The bank reports the full interest amount on a single 1099-INT, and you and the other owner must decide how to split it for tax purposes.

Usually, you split the interest 50/50 unless you have a different agreement in writing. Each person reports their share on their own tax return. The bank doesn't split the 1099-INT — you handle that division yourselves.

If you're married and file jointly, this is simpler because you report all household income together anyway. If you're unmarried or file separately, make sure both people report their share to avoid discrepancies with the IRS.

Frequently Asked Questions

Do I have to report checking account interest if it's under $10?

Your bank won't send a 1099-INT if you earned less than $10, but you still owe tax on that interest if you file a return. Use your bank statements to calculate what you earned and report it on your return. The IRS doesn't know about it unless you tell them, but underreporting is risky.

What if I close my checking account mid-year — do I still owe tax on the interest?

Yes. You owe tax on all interest earned during the calendar year, regardless of when you close the account. Your bank will still send a 1099-INT for the interest earned before you closed it.

Can I deduct checking account fees from the interest I report?

No. You report the gross interest your bank paid you, not the net after fees. Checking account fees are not deductible on your personal tax return (though business account fees may be deductible if you're self-employed).

Is interest from a checking account at a credit union taxed the same way?

Yes. Credit unions report interest the same way banks do — on a 1099-INT if you earned $10 or more. The tax treatment is identical to bank interest.

Do I need to report interest if I'm claimed as a dependent?

If you're a dependent, you still owe tax on interest you earned, but the rules for filing a return are different. Generally, if your only income is interest under a certain threshold (which changes yearly), you may not have to file. Check the IRS website or ask a tax preparer whether you need to file based on your specific situation.
