You only pay taxes on interest your bank pays you, not on the balance itself

The money sitting in your checking account is not taxable income. You do not owe federal income tax on the principal—the amount you deposited. However, if your bank pays you interest on that balance, that interest is taxable income and must be reported to the IRS.

Most checking accounts pay little or no interest, so many people never face this issue. But some accounts—particularly high-yield checking accounts or money market accounts—do pay interest. If your account earned any interest during the year, your bank will send you a form showing how much, and you will need to report it on your tax return.

The threshold for reporting is low. If you earned $10 or more in interest from a single bank during the calendar year, the bank must send you a Form 1099-INT by January 31 of the following year. Even if you earned less than $10, you still owe tax on it—the bank just is not required to report it to you in writing.

Key Takeaways

  • Your checking account balance itself is never taxable; only interest paid by the bank counts as income.
  • Banks send Form 1099-INT when interest reaches $10 or more in a calendar year, but you owe tax on any interest earned.
  • Interest income is reported on your federal tax return and taxed at your ordinary income tax rate.
  • Some states also tax interest income, so check your state's rules if you live outside a no-income-tax state.

How banks report interest to the IRS

Your bank tracks all interest paid to your account during the calendar year (January 1 through December 31). If the total reaches $10 or more, the bank generates a Form 1099-INT and mails it to you and files a copy with the IRS. This form shows your account number, the bank's name and ID number, and the exact amount of interest paid.

You receive the 1099-INT by January 31. You then report that interest on your federal tax return—usually on Schedule B (Interest and Ordinary Dividend Income) if you use the long form, or directly on line 1b of Form 1040 if the amount is small and you use the short form. The IRS receives a copy of the same 1099-INT, so they know what you earned.

If you earned interest but did not receive a 1099-INT because it was under $10, you still must report it. Keep your bank statements or year-end summary as proof of the amount.

What tax rate applies to interest income

Interest from a checking account is taxed as ordinary income, meaning it is added to your wages, salary, and other income and taxed at your regular federal income tax rate. If you are in the 22% tax bracket, interest is taxed at 22%. If you are in the 12% bracket, it is taxed at 12%.

This is different from capital gains or may have access to dividends, which may have lower tax rates. Interest is always ordinary income, no matter the source or the account type.

Your employer withholds income tax from your paycheck based on a W-4 form you fill out. Interest income is not subject to withholding—the bank does not take tax out. This means you may owe additional tax when you file your return, or you may have already overpaid through paycheck withholding and receive a refund.

State taxes on interest income

Nine states have no income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only interest and dividend income, but at a low rate). If you live in one of these states, you owe no state tax on your checking account interest.

If you live in any other state, that state likely taxes interest income the same way the federal government does—as ordinary income at your state tax rate. Some states have lower rates than others. You will need to report the same 1099-INT interest on your state tax return as well.

A few states offer tax breaks for interest earned on certain savings vehicles (like 529 college savings plans), but regular checking account interest does not may have access to for these breaks.

When interest is so small it barely matters

Most traditional checking accounts pay zero interest or a fraction of a percent. A $5,000 balance earning 0.01% annually generates 50 cents—well below the $10 reporting threshold and unlikely to change your tax bill meaningfully.

High-yield checking accounts, by contrast, may pay 4% to 5% annually. A $10,000 balance at 4.5% generates $450 in interest per year, which is significant and will definitely appear on a 1099-INT.

Even if the amount is small, report it correctly. The IRS matches 1099-INT forms to tax returns, and underreporting interest is a red flag for audits, even when the dollar amount is trivial.

What happens if you do not report interest income

If you receive a 1099-INT and do not report the interest on your tax return, the IRS will notice the discrepancy when they match the form to your return. This can trigger a notice asking you to explain the missing income, or in some cases, the IRS may assess additional tax, penalties, and interest on the unreported amount.

The penalty for underreporting income is typically 20% of the underpaid tax, plus interest calculated from the original due date. For small amounts, the dollar penalty may be modest, but it compounds if you make the same mistake year after year.

Reporting the interest takes minutes and costs nothing. It is far simpler than dealing with an IRS notice later.

Frequently Asked Questions

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

Yes. The $10 threshold only determines whether the bank must send you a 1099-INT form. You still owe tax on any interest earned, even $1. Report it on your return using your bank statements as proof.

Is interest from a joint checking account taxed differently?

No. Interest is taxed the same way regardless of account ownership. If the account is joint, the bank may split the interest between owners on separate 1099-INT forms, or report it all to one owner—check your forms. Report your share on your return.

What if I closed the account mid-year—do I still owe tax on the interest earned before closing?

Yes. Interest earned up to the date you closed the account is taxable income for that year. The bank will report it on a 1099-INT if it reaches $10, or you can report it yourself using your final statement.

Can I deduct checking account fees to offset the interest income?

No. Checking account fees are not deductible on your federal return. You must report the full interest amount as income, even if fees nearly wiped out the earnings.

Do I need to report interest from a savings account or money market account the same way?

Yes. Interest from any bank account—checking, savings, money market, or certificate of deposit—is reported on Form 1099-INT and taxed as ordinary income using the same process.
