You pay income tax on savings account interest at your ordinary tax rate

The interest your bank pays you on a savings account is taxed as ordinary income, the same way wages are taxed. If your savings account earned $500 in interest last year, that $500 counts as income on your tax return. You pay tax on it at whatever rate applies to your total income — which could be 10%, 12%, 22%, or higher, depending on your tax bracket.

The bank reports this interest to the IRS on a Form 1099-INT if you earned $10 or more in interest during the year. You receive a copy in January or early February, and you report the amount on your tax return. If you earned less than $10, the bank does not have to send a form, but you still owe tax on the interest if you file a return.

No tax is withheld from the interest before you receive it — the money goes into your account in full, and you handle the tax bill when you file. This is different from wages, where your employer withholds tax upfront.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your regular tax bracket rate, not at a special lower rate.
  • Banks report interest of $10 or more on Form 1099-INT, which you receive by early February and report on your tax return.
  • No tax is taken out of your interest before it reaches your account — you pay the full amount when you file your return.
  • Interest earned in a regular savings account is taxed every year, but interest in certain accounts like Roth IRAs or 529 plans may not be taxed at all.

How your tax bracket determines what you actually pay

The tax rate on your interest depends on your total income for the year, not just the interest itself. If you earn $35,000 in wages and $500 in interest, your total taxable income is $35,500. That $500 is taxed at whatever marginal rate applies to your income level.

For 2024, if you are single and your total income falls between $11,600 and $47,150, you are in the 12% tax bracket. That means the interest is taxed at 12%. If your income is higher, the rate goes up. If it is lower, the rate may be 10%. The exact brackets change each year and depend on whether you file as single, married filing jointly, head of household, or another status.

This matters because a small amount of interest can push you into a higher bracket. If you are close to a bracket boundary, earning an extra $500 in interest might cost you more than $50 in tax, not just $60 (which would be 12% of $500). The IRS taxes the interest at the rate that applies to your highest dollar of income.

When you do not pay tax on savings interest

Interest earned inside a Roth IRA or Roth 401(k) is never taxed, as long as you follow the withdrawal rules. The same is true for interest in a 529 education savings plan — it grows tax-free if you use the money for may have access to education expenses. Interest in a Health Savings Account (HSA) is also tax-free if withdrawn for medical costs.

A traditional IRA or traditional 401(k) defers the tax: you do not pay tax on the interest while it sits in the account, but you pay ordinary income tax on the full balance when you withdraw it in retirement. This is different from a regular savings account, where you pay tax every year on the interest earned that year.

Some states do not tax interest income at all — if you live in Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, or Wyoming, you owe no state income tax on your savings interest. Other states tax it the same way the federal government does.

What happens if you earn interest but do not file a return

If you earned $500 in interest and the bank sent you a Form 1099-INT, the IRS has a copy too. If you do not report it on your return, the IRS will eventually notice the mismatch between what the bank reported and what you filed. This can trigger a notice asking you to explain the discrepancy or pay the tax you owe, plus penalties and interest.

Even if you do not normally file a return because your income is below the threshold, you should file one if you received a 1099-INT. The safe approach is to report all interest income, no matter how small. If you are unsure whether you need to file, the IRS website has a filing requirement tool, or you can contact a tax professional.

How to report interest on your tax return

When you file your return, you report the interest amount from your Form 1099-INT on Schedule 1 (Form 1040), line 8b, or directly on the main Form 1040 depending on the year and your software. If you use tax software, you enter the amount and it flows to the right place automatically. If you file by hand, the instructions that come with Form 1040 show where to put it.

If you have multiple savings accounts at different banks, each bank sends its own 1099-INT. You add up all the interest from all the forms and report the total. The IRS does not care how many accounts you have — they only care about the total interest income.

If you earned interest but did not receive a 1099-INT (because it was under $10, or the bank made a mistake), you still report it. Write the amount on the return and note that no form was issued. The IRS expects you to report all interest, whether or not a form was sent.

Interest rates and how much tax you will owe

Higher interest rates mean more tax. A high-yield savings account earning 4% or 5% generates more interest than a regular savings account earning 0.01%, so you owe more tax on the earnings. If you have $10,000 in a high-yield account earning 4.5%, you earn about $450 per year. At a 12% tax rate, that costs you roughly $54 in federal tax. At a 22% rate, it costs about $99.

This is one reason some people move money to tax-advantaged accounts like IRAs or 529 plans when they have a large balance. The interest grows without being taxed every year, which can add up over time. For smaller balances or shorter time periods, the tax hit is usually modest.

Keep in mind that your actual tax bill depends on your full income picture, not just the interest. A financial advisor or tax professional can help you understand how interest income affects your specific situation.

Frequently Asked Questions

Do I have to pay tax on interest if I reinvest it back into the account?

Yes. The tax is based on the interest earned, not on what you do with it afterward. If your account earned $200 in interest and you let it sit in the account instead of withdrawing it, you still owe tax on that $200. The IRS taxes interest the year it is earned, regardless of whether you spend it, reinvest it, or leave it alone.

What if I earned less than $10 in interest — do I still report it?

The bank does not have to send a Form 1099-INT for interest under $10, but you should still report it on your return if you file one. The IRS expects all income to be reported. If you do not file a return for other reasons, you do not need to file just for the small interest amount, but reporting it is the safest approach.

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

No. You report the gross interest the bank paid you, not the interest minus fees. Savings account fees are not tax-deductible. You report the full amount on the 1099-INT, and that is what goes on your return.

Is interest taxed differently if I am retired?

No. Interest is taxed at your ordinary income tax rate regardless of your age or employment status. However, if your total income in retirement is lower than when you were working, you may be in a lower tax bracket, which means the interest is taxed at a lower rate. Some retirees also benefit from tax-advantaged accounts they set up before retirement.

What if my savings account is in a child's name?

Interest earned in a child's account is taxed to the child, not the parent. The child receives the 1099-INT and reports it on their own return (or the parent reports it on a dependent return if the child does not file). There are special rules called the "kiddie tax" that may apply if the child is under 18 and has unearned income, but the interest is still reported.
