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

The interest your bank pays you on a savings account is taxable income. The IRS treats it the same way it treats wages or salary — you owe federal income tax on the full amount. Your tax rate depends on your total income for the year and your filing status, not on the size of the interest payment itself.

The bank reports this interest to the IRS on a Form 1099-INT if you earned $10 or more in interest during the tax year. You receive a copy in January or early February. You then report that same amount on your tax return, usually on Schedule 1 (Form 1040) or directly on the 1040 itself, depending on which form you file.

State income tax works the same way in most states — you owe state tax on savings interest at your state's ordinary rate. A handful of states (including Pennsylvania, New Hampshire, and Tennessee) do not tax interest income at all, so your state matters.

Key Takeaways

  • Savings interest is taxed as ordinary income at your federal tax bracket, whether that is 10%, 22%, 24%, or higher.
  • Banks report interest of $10 or more on Form 1099-INT, which you must include on your tax return.
  • Most states tax savings interest the same way the federal government does, but a few states do not tax it at all.
  • High-yield savings accounts earn more interest, which means you owe more tax — the tax rate itself does not change, only the amount of interest subject to tax.

How your tax bracket determines what you actually owe

Your federal tax rate on savings interest is not a flat percentage — it depends on your tax bracket, which is determined by your total income for the year. If you earn $50,000 in wages and $500 in savings interest, your interest is taxed at whatever bracket your $50,500 total income falls into, not at a separate rate.

For 2024, the federal tax brackets range from 10% (lowest income) to 37% (highest income). If you are in the 22% bracket, you owe 22% tax on your savings interest. If you are in the 12% bracket, you owe 12%. The interest itself does not move you into a higher bracket — it is simply added to your other income and taxed accordingly.

This matters because a high-yield savings account earning 4% or 5% annual interest sounds good until you realize that interest is fully taxable. A $10,000 deposit earning 5% generates $500 in interest, on which you owe tax at your bracket rate. If you are in the 24% bracket, that is $120 in federal tax, leaving you with $380 in actual after-tax gain.

When you receive the Form 1099-INT and what to do with it

Banks send Form 1099-INT in January or early February for the previous calendar year. You receive it if you earned $10 or more in interest during that year. The form shows the total interest paid to you, broken down by account if you have multiple accounts at the same bank.

You do not need to do anything with the form immediately — just keep it with your tax documents. When you file your tax return, you report the interest amount shown on the 1099-INT on your return. The IRS also receives a copy of the form, so the amount you report should match what the bank reported. If it does not, the IRS will notice and contact you.

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 can find the exact amount in your account statements or online banking portal.

State taxes on savings interest vary widely

Most states tax savings interest as ordinary income, using the same approach as the federal government. Your state tax rate is added on top of your federal rate. If you live in a state with a 5% income tax and you are in the 22% federal bracket, you owe 27% total tax on your savings interest.

A few states do not tax interest income at all. Pennsylvania, New Hampshire, Tennessee, and South Dakota have no tax on interest or dividends. If you live in one of these states, you owe only federal tax on your savings interest, not state tax. This can make a meaningful difference if you have substantial savings earning interest.

Some states tax interest but offer small exemptions — for example, Illinois excludes the first $100 of interest income per person per year. Check your state's tax agency website or your state income tax form to see whether your state taxes interest and whether any exemptions apply to you.

How to report savings interest on your tax return

On your federal return, you report savings interest on Schedule 1 (Form 1040), line 8b, labeled "Interest." If you use tax software, it will prompt you to enter this amount. If you file by hand, you write the total interest from all your 1099-INT forms on that line, then transfer the amount to your Form 1040.

If you have interest income from multiple banks or savings accounts, add them all together and report the total on one line. You do not list each account separately on the return itself, though you should keep the 1099-INT forms for your records.

On your state return, look for a line labeled "Interest Income" or "Dividends and Interest." The process is similar — you report the total amount. Some states use the same amount as your federal return; others have different rules or exemptions, so check your state form.

What happens if interest is reported to the IRS but you do not report it

The IRS receives a copy of every 1099-INT the bank sends to you. If you do not report that interest on your tax return, the IRS will eventually notice the mismatch between what the bank reported and what you reported. This can trigger a notice asking you to explain the discrepancy or pay the tax you owe plus penalties and interest.

The penalty for underreporting income is typically 20% of the underpaid tax, plus interest that accrues from the original due date. If the underreporting is deemed intentional, the penalty can be higher. It is far simpler to report the interest when you file.

If you earned less than $10 and received no 1099-INT, you are still required to report that interest, but the IRS is less likely to catch it. That said, the tax obligation exists regardless of whether a form was issued.

Strategies to reduce taxes on savings interest

You cannot avoid tax on savings interest, but you can reduce the amount of interest you earn and therefore the tax you owe. This sounds counterintuitive, but it matters in specific situations. If you are in a very high tax bracket, the after-tax return on a high-yield savings account earning 4% might be lower than the after-tax return on a bond or stock investment that qualifies for lower capital gains tax rates.

Another option is to hold savings in tax-advantaged accounts if you are saving for a specific purpose. Money in a Health Savings Account (HSA) grows tax-free if used for medical expenses. Money in a 529 college savings plan grows tax-free if used for education. Money in a traditional IRA or 401(k) grows tax-deferred, meaning you do not owe tax on the interest until you withdraw it in retirement.

For ordinary savings outside these accounts, there is no way to avoid the tax. You owe it on the interest earned, at your ordinary tax rate, regardless of how much or how little you earn.

Frequently Asked Questions

Do I owe tax on savings interest if I do not withdraw the money?

Yes. Tax is owed on interest in the year it is earned, whether you withdraw it or leave it in the account. The IRS taxes the interest when the bank credits it to your account, not when you move the money.

What if my savings interest is less than $10?

You still owe tax on it, but the bank does not have to send you a 1099-INT. You can find the exact amount in your account statements. Report it on your tax return even if you did not receive a form.

Is savings interest taxed differently than other income?

No. Savings interest is taxed as ordinary income at your regular tax bracket, the same as wages or salary. It does not receive the lower tax rate that long-term capital gains do.

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

No. You report the full interest amount on your tax return. Savings account fees are not deductible for most taxpayers, so you cannot offset the interest with them.

What if I moved money between banks during the year?

Each bank reports only the interest it paid you while you held money there. Add up all the 1099-INT forms you receive and report the total on your tax return. Moving money does not change your tax obligation — you owe tax on all interest earned during the year.
