The IRS treats savings account interest as ordinary income, taxed at your regular income tax rate

Every dollar of interest your bank pays you counts as taxable income. The IRS does not separate interest income from wages or salary — it all goes into the same tax calculation. If your savings account earned $500 in interest last year, you owe federal income tax on that $500 at whatever rate applies to your total income for the year. Most people in lower tax brackets pay 10% or 12% on interest income. People in higher brackets pay 22%, 24%, or more.

Your bank reports this interest to the IRS on a Form 1099-INT, which you receive by January 31 each year. The form shows the total interest paid to you during the previous calendar year. You must report this amount on your federal tax return, even if the bank did not send you a 1099-INT (though they should have). State income tax works the same way — most states tax savings interest as ordinary income at your state tax rate.

The amount of interest you earn depends on the account type and the bank's rate. High-yield savings accounts currently pay between 4% and 5% annually, while traditional savings accounts often pay less than 1%. A $10,000 balance in a high-yield account might earn $400 to $500 per year; the same balance in a traditional account might earn $20 to $50. All of it is taxable.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your federal and state tax rates, not at a special lower rate.
  • Your bank reports interest on Form 1099-INT by January 31, and you must include this amount on your tax return.
  • You owe tax on interest even if you do not withdraw it from the account or reinvest it.
  • Interest earned in tax-advantaged accounts like Roth IRAs or 529 plans is not taxed the same way, but regular savings accounts have no tax shelter.

When you receive a 1099-INT and what it means

Banks send Form 1099-INT to customers who earned $10 or more in interest during the calendar year. The form lists the account number, the total interest paid, and sometimes a breakdown by account type if you have multiple accounts at the same bank. You receive it by January 31 of the following year — so interest earned in 2024 appears on a 1099-INT you get in January 2025.

If you earned less than $10 in interest, the bank may not send a 1099-INT, but you still owe tax on that interest. You report it on your return even without the form. If you earned more than $10 and did not receive a 1099-INT by early February, contact the bank directly. They can reissue it or provide the information you need.

The 1099-INT goes to both you and the IRS. This means the IRS already knows about your interest income before you file your return. If you do not report it, the IRS will likely catch the discrepancy and send you a notice. Reporting it yourself avoids penalties and interest charges.

How your tax bracket determines what you actually pay

The tax rate on interest income depends on your total income for the year, not on the interest alone. If you earn $35,000 in wages and $500 in interest, your total taxable income is $35,500. That $500 is taxed at whatever rate applies to the top portion of your income — which might be 12% if you are single, or 10% if you are married filing jointly and still in the lower bracket.

A person in the 22% tax bracket who earns $1,000 in interest will owe roughly $220 in federal tax on that interest. A person in the 10% bracket will owe roughly $100. State tax varies by location — some states have no income tax, while others tax interest at rates between 3% and 13%.

This is why the same $1,000 in interest costs different people different amounts. It is also why earning interest in a high-yield account (which pays more) can push you into a higher tax bracket if your total income is close to a bracket boundary. This is rare for most people, but it is worth knowing if you have substantial savings.

Interest earned but not withdrawn still counts as taxable income

You owe tax on interest the moment the bank credits it to your account, whether you touch the money or not. If you leave the interest in the account to compound, you still report it on your tax return that year. If you reinvest it into another account or product, you still owe tax on it in the year earned.

This is different from capital gains on investments, where you may not owe tax until you sell. With savings interest, the tax obligation happens automatically when the bank pays the interest. The IRS considers it income received, even if you never withdraw it.

Tax-advantaged accounts that shelter interest from taxation

Regular savings accounts offer no tax break. But certain accounts do shelter interest from federal tax, at least temporarily or permanently. A Roth IRA or Roth 401(k) allows interest to grow tax-free forever, as long as you follow withdrawal rules. A traditional IRA or 401(k) defers tax on interest until you withdraw the money in retirement. A 529 education savings plan lets interest grow tax-free if used for may have access to education expenses.

These accounts have contribution limits and withdrawal restrictions, so they are not right for all savings goals. But if you have money you will not need for years, moving it into one of these accounts can save you significant tax on the interest it earns. A $50,000 balance earning 5% annually ($2,500 per year) in a regular savings account costs you roughly $250 to $550 per year in federal tax alone, depending on your bracket. In a Roth IRA, that same $2,500 is never taxed.

What to do if you earned interest but did not receive a 1099-INT

If you earned $10 or more in interest and your bank did not send a 1099-INT by early February, call the bank's customer service line. Have your account number ready. Ask them to reissue the form or provide the total interest paid in the previous year. Most banks can do this within a few business days.

If the bank cannot locate the form or says they did not send one, ask for a written statement showing the interest credited to your account for each month of the year. You can use this to calculate the total and report it on your return. Keep a copy for your records.

Do not skip reporting the interest just because you did not receive a 1099-INT. The IRS has records of your account and will notice if you do not report it. It is much easier to report it yourself than to deal with an IRS notice later.

How to report savings interest on your tax return

On your federal return, you report interest income on Schedule B (Interest and Ordinary Dividends) if you have more than $1,500 in interest and dividends combined. If you have less than $1,500, you can report it directly on Form 1040, line 2b. Include the total from all your 1099-INT forms.

State returns vary. Most states have a line for interest income on their main return form. Check your state's tax department website or your state return instructions to find where to report it. If you use tax software, it usually walks you through this step and pulls the information from your 1099-INT automatically.

Keep your 1099-INT forms and any bank statements showing interest paid. You do not send them with your return, but the IRS can ask for them if they audit you. Holding onto them for at least three years is standard practice.

Frequently Asked Questions

Do I owe tax on interest if I have not withdrawn it from the account?

Yes. The IRS taxes interest in the year it is earned and credited to your account, regardless of whether you withdraw it, leave it there, or reinvest it. You report it on your tax return even if the money never leaves the bank.

What if I have interest from multiple banks or accounts?

Add up all the interest from all your 1099-INT forms and report the total on your return. If you have more than one account at the same bank, the bank usually combines them into a single 1099-INT. If you have accounts at different banks, you will receive separate forms from each one.

Can I deduct any expenses against my interest income?

No. Interest income is reported as-is with no deductions. You cannot reduce it by account fees, investment losses, or other costs. However, if you have investment losses in stocks or bonds, those can offset capital gains or reduce other income — but not interest income specifically.

Is interest taxed differently if I am retired or on a fixed income?

No. Interest is taxed at your regular rate regardless of your age or income source. However, if your total income is low enough, you may not owe federal tax at all. The standard deduction shields a certain amount of income from tax each year — in 2024, that is $14,600 for single filers and $29,200 for married couples filing jointly.

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

Contact the bank immediately and ask them to issue a corrected form (Form 1099-INT with a "CORRECTED" label). Once you receive it, file an amended return if you already filed. If the error is small and you have not filed yet, just report the correct amount on your original return and keep the corrected 1099-INT for your records.
