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. Most checking accounts earn little or no interest, so many people never see a tax bill from it. But if your account does earn interest, you will report it.

Your bank sends you a Form 1099-INT each January for the previous year if you earned $10 or more in interest. You then report that amount on your federal tax return. Some states also tax interest income, though the rules vary by state.

Key Takeaways

  • Banks report checking account interest to the IRS on Form 1099-INT when you earn $10 or more in a calendar year.
  • You report the interest amount on your federal tax return as ordinary income, subject to your regular tax rate.
  • Some states tax interest income and some do not, depending on where you live and file taxes.
  • Interest earned is taxable even if you do not receive a 1099-INT form, so keep your own records of what the bank paid you.

How the IRS knows about your interest

Banks are required to report interest payments to the IRS. If your checking account earned $10 or more in interest during the calendar year, your bank will mail you a Form 1099-INT by January 31 of the following year. The form shows the total interest paid to you in the previous year.

The bank sends a copy to the IRS at the same time. This means the IRS already knows how much interest you earned before you file your return. If you do not report it, the IRS will notice the discrepancy between what the bank reported and what you claimed.

If you earned less than $10 in interest, your bank may not send a 1099-INT, but the interest is still taxable. You should track it yourself and report it on your return.

Where you report the interest on your tax return

On the federal Form 1040, interest income goes on Schedule 1, line 8a (labeled "Interest"). You add up all interest from all sources — checking accounts, savings accounts, money market accounts, bonds, and any other interest-bearing accounts — and report the total.

The interest is then added to your other income and taxed at your ordinary income tax rate. If you are in the 22% tax bracket, for example, and you earned $100 in checking account interest, you will owe roughly $22 in federal tax on that interest (before any deductions or credits reduce your overall tax bill).

If you file state income taxes, you will also report the interest on your state return. Most states follow the federal rule and tax interest as ordinary income, but a few states do not tax interest income at all. Check your state's tax rules or speak with a tax preparer about your specific situation.

Why most checking accounts earn little or no interest

Most traditional checking accounts offered by large banks pay zero interest or a rate so low it rounds to zero. A balance of $5,000 might earn $0.50 per year. This is why most people never receive a 1099-INT for a checking account — the interest is too small to trigger the $10 reporting threshold.

High-yield checking accounts, offered by online banks and some credit unions, do pay meaningful interest. These accounts might pay 4% to 5% annual interest, depending on the current rate environment. If you keep $10,000 in such an account, you could earn $400 to $500 per year, which will definitely show up on a 1099-INT and be taxable.

State taxes on interest income

Most states tax interest income the same way the federal government does — as ordinary income. However, a handful of states do not tax interest at all. These include Illinois (for residents), Mississippi, and a few others. If you live in one of these states, you may owe federal tax on your checking account interest but no state tax.

If you live in a state that does tax interest, the rate depends on your state income tax bracket. Some states have a flat tax rate; others use brackets like the federal system. Your state tax return will have a line for interest income, similar to the federal form.

What to do if you do not receive a 1099-INT

If your bank does not send you a 1099-INT because your interest was under $10, you still owe tax on it. The IRS expects you to report all income, whether or not you receive a form. Keep a record of the interest your account earned — most banks show this on your monthly or annual statement.

If you earned interest from multiple accounts, add them all together. Even if no single account crossed the $10 threshold, the combined total might be significant enough to matter on your return.

Interest on checking accounts versus other savings vehicles

Checking account interest is taxed the same way as interest from savings accounts, money market accounts, and certificates of deposit. The only difference is the rate — checking accounts typically pay less. All of these are reported on the same line of your tax return.

This is different from capital gains, which are taxed at potentially lower rates, or from tax-advantaged accounts like IRAs or 401(k)s, where interest grows without when ready tax. A regular checking account offers no tax shelter, so all interest is taxable in the year it is earned.

Frequently Asked Questions

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

Yes. The $10 threshold only determines whether your bank sends you a 1099-INT form. You are required to report all interest income on your tax return, regardless of the amount. If you earned $3 in interest, it is still taxable.

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

Contact your bank and ask them to issue a corrected form. They will send you a corrected 1099-INT and file a corrected copy with the IRS. Do not file your tax return until you have the correct form, or you may need to file an amended return later.

Can I deduct anything against the interest I earned?

No. Interest income is reported in full on your tax return. You cannot deduct the interest you paid on a personal loan or credit card against interest you earned on a checking account. Those are separate items on your return.

Is interest on a joint checking account split between the two owners for tax purposes?

The bank reports the full interest amount on a 1099-INT. If the account is truly joint and both owners contributed equally, you may split the interest 50/50 on your individual returns, but you will need to keep documentation of the arrangement. The IRS may ask for proof if there is a discrepancy.

What happens if I move money between accounts during the year?

You report all interest earned in that calendar year, regardless of when you moved the money or which account it was in. If you earned $50 in one account and $30 in another, you report $80 total. The timing of transfers does not change the tax treatment.
