Yes, you must report savings account interest as income on your tax return

The IRS treats interest earned in a savings account as taxable income. That means if your bank paid you interest during the year, you owe federal income tax on that amount — even if the interest was small. Your bank will send you a form called a 1099-INT in January showing how much interest you earned, and you report that figure on your tax return.

The threshold for reporting is low. Banks must send you a 1099-INT if you earned $10 or more in interest during the calendar year. But you may owe tax on interest below $10 as well — the $10 threshold is just when the bank is required to report it to you and the IRS. If you earned $5 in interest and your tax bracket means you owe tax on that $5, you still need to report it.

The amount of tax you actually owe depends on your total income and your tax bracket. Interest is added to your other income and taxed at your ordinary income rate, which can range from 10% to 37% depending on how much you earn overall. A high-yield savings account earning 4% or 5% annually will generate more taxable interest than a traditional savings account earning 0.01%, so the tax impact varies widely.

Key Takeaways

  • Banks send a 1099-INT form when interest reaches $10 or more, but you must report all interest income regardless of the amount.
  • Interest is taxed as ordinary income at your marginal tax rate, which means the tax you owe depends on your total income for the year.
  • High-yield savings accounts generate more taxable interest than traditional accounts, so the tax impact is larger with those accounts.
  • You report savings account interest on your federal tax return; some states also tax interest income, depending on where you live.
  • If you did not receive a 1099-INT but earned interest, you still report that interest on your return using the amount shown in your account statements.

How the 1099-INT form works and what it shows

Your bank generates a 1099-INT for each account where you earned $10 or more in interest during the calendar year. The form shows your name, Social Security number, the bank's name and tax ID, and the total interest paid to that account. You receive one copy in the mail by January 31, and the bank sends a copy to the IRS at the same time.

If you have multiple savings accounts at different banks, you will receive a separate 1099-INT from each bank. If you have multiple accounts at the same bank, the bank may combine the interest on one form or issue separate forms depending on how the accounts are registered. Check the form carefully to make sure the interest amount matches your account statements — errors do happen, and you can ask the bank to issue a corrected form if the number is wrong.

The 1099-INT also reports interest from money market accounts, certificates of deposit (CDs), and interest-bearing checking accounts. It does not report interest from bonds, Treasury securities, or municipal bonds — those use different forms. When you file your tax return, you enter the total interest from all your 1099-INT forms on Schedule 1 (Form 1040), which feeds into your taxable income calculation.

What happens if you earn interest below the $10 reporting threshold

If you earned less than $10 in interest, your bank will not send you a 1099-INT. But you still owe tax on that interest if your tax situation requires you to file a return. You report it using the amount shown in your account statements or your year-end account summary.

The $10 threshold is purely a reporting requirement — it does not mean interest below that amount is tax-free. If you have a savings account earning $8 in interest and you are required to file a return, you report that $8 on your tax return. The IRS expects you to track and report all interest income, whether or not you receive a 1099-INT.

To keep track, check your account statements each month or review your year-end summary from your bank. Many online banks show year-to-date interest earned in your account dashboard, making it straightforward to know the total before tax season arrives.

State income tax on savings account interest

Most states that have an income tax also tax interest income at the state level. The rate varies by state, and some states exempt interest income entirely. For example, some states do not tax interest from savings accounts, while others tax it at the same rate as federal income tax or at a flat rate.

You will report state interest income on your state tax return, usually on a form similar to your federal return. Some states use the federal 1099-INT as the basis for their calculation, while others require you to report interest separately. Check your state's tax authority website or your state tax form instructions to understand how interest is taxed where you live.

If you live in a state with no income tax — such as Florida, Texas, or Wyoming — you do not owe state tax on savings account interest. You still owe federal tax, but the state portion is zero.

How interest income affects your tax bracket and refund

Interest income is added to your other income — wages, self-employment income, investment gains — to calculate your total taxable income. That total determines which tax bracket you fall into and how much tax you owe overall. If you are close to the edge of a tax bracket, a large amount of interest could push you into a higher bracket and increase your tax bill.

For example, if you earned $50,000 in wages and $2,000 in interest, your taxable income is $52,000. That $2,000 in interest is taxed at your marginal rate — the rate that applies to your highest dollars of income. If you are in the 22% bracket, you owe roughly $440 in federal tax on that interest (before accounting for deductions and credits).

Interest income can also affect whether you may have access to for certain tax deductions or credits. Some credits phase out as your income rises, so additional interest income could reduce or eliminate a credit you would otherwise receive. This is especially relevant if you are near the income limit for credits like the Earned Income Tax Credit or education credits.

Reporting interest when you did not receive a 1099-INT

If you earned interest but your bank did not send a 1099-INT — either because the amount was below $10 or because of a bank error — you still report that interest on your tax return. Use your account statements or year-end summary to find the total interest earned.

Enter the interest on Schedule 1 (Form 1040) under "Interest" just as you would if you had received a 1099-INT. The IRS cross-checks 1099-INT forms against tax returns, so if you received a form, make sure the amount you report matches. If you did not receive a form but earned interest, report what you actually earned based on your statements.

If you believe your bank made an error and did not send a 1099-INT when it should have, contact the bank and ask for a corrected form. Most banks will issue one if you request it, and they will send a copy to the IRS as well. This prevents a mismatch between what you report and what the IRS sees.

Interest from joint accounts and accounts held in trust

If you own a savings account jointly with another person, the bank reports the total interest on a 1099-INT. You and the joint owner must decide how to split that interest for tax purposes — usually 50-50 unless you have a different ownership arrangement. Each person reports their share on their own tax return.

The bank does not automatically split the interest between you; you handle that when you file. If you and a joint account holder disagree on how to split the interest, you may need to provide documentation of your ownership percentages to the IRS if questioned.

For accounts held in trust or in the name of a minor, the reporting rules are more complex. A trust may have its own tax ID and file its own return, in which case the interest is reported on the trust's return, not the beneficiary's. If the account is in a child's name, the interest is reported on the child's return (though parents may claim the child as a dependent). Consult a tax professional if you are unsure how to report interest from a trust or custodial account.

Frequently Asked Questions

Do I have to pay taxes on interest if I earned less than $10?

Yes. The $10 threshold is when banks must send a 1099-INT form, not when interest becomes taxable. If you earned any interest and are required to file a tax return, you report all of it. Use your account statements to find the amount if you did not receive a 1099-INT.

What if my bank sent me a 1099-INT with the wrong amount?

Contact your bank and ask for a corrected form (called an amended 1099-INT). The bank will issue a corrected form and send it to both you and the IRS. Report the corrected amount on your tax return, not the original incorrect amount.

Can I deduct interest I paid on a loan from the interest I earned in savings?

No. Interest you earn is income you must report. Interest you pay on a loan (like a mortgage or student loan) may be deductible under separate rules, but you cannot offset one against the other. Report all interest income and claim any deductible interest separately.

Do I owe taxes on interest if I am retired and do not usually file a tax return?

You may be required to file a return if your interest income alone exceeds the standard deduction for your age and filing status. Even if you are not required to file, you may want to file anyway if taxes were withheld from other income, because you could receive a refund. Check the IRS website or consult a tax professional to determine whether you must file.

Is interest from a high-yield savings account taxed differently than interest from a regular savings account?

No. Interest is taxed the same way regardless of the account type or the rate. A high-yield account earning 4% generates more taxable interest than a traditional account earning 0.01%, so your tax bill will be larger, but the tax treatment is identical.
