Interest on savings accounts is taxed as ordinary income at your federal tax rate

The tax you owe on savings account interest depends on your overall income and tax bracket, not on the savings account itself. Banks report the interest you earn each year on a Form 1099-INT, and you report that amount on your federal tax return. The IRS treats savings interest the same way it treats wages or salary — it's added to your total income and taxed at whatever rate applies to you.

If you earned $500 in savings interest and you're in the 22% federal tax bracket, you owe roughly $110 in federal tax on that interest. But if you're in the 12% bracket, you owe roughly $60. The exact amount also depends on whether you have other income, deductions, or credits that reduce your taxable income.

Most savings accounts earn very little interest — often less than 1% annually — so the tax bill is usually small. A $10,000 account earning 0.5% interest generates $50 per year, which means roughly $11 in federal tax if you're in the 22% bracket. But high-yield savings accounts can earn 4% or more, which means more interest and a larger tax bill.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your federal tax rate, which ranges from 10% to 37% depending on your total income.
  • Banks send you a Form 1099-INT each January reporting the interest you earned, and you must report this on your federal tax return.
  • State and local income taxes also explore to savings interest in most states, adding another 3% to 13% on top of federal tax.
  • You owe tax on interest even if the bank does not withhold it, so plan ahead if you earn significant interest income.
  • Some savings accounts and accounts for minors have tax advantages, but most regular savings accounts offer no tax break.

Federal tax brackets and how they affect your savings interest

Your federal tax rate on savings interest is determined by your tax bracket, which depends on your total income for the year. The federal system has seven brackets ranging from 10% to 37%. If you earn $50,000 in wages and $500 in savings interest, your total taxable income is $50,500, and the interest is taxed at whatever bracket that total puts you in.

For 2024, a single filer with $50,500 in income falls into the 22% bracket. That means the $500 in savings interest is taxed at 22%, resulting in a $110 federal tax bill on that interest alone. If you were married filing jointly with the same income, you'd be in the 12% bracket, and the tax would be $60.

The brackets change each year for inflation, so your rate may shift from year to year even if your income stays the same. The IRS publishes updated brackets in October for the following tax year, and most tax software updates automatically.

State and local taxes on savings interest

In addition to federal tax, most states tax savings interest as ordinary income. State rates range from roughly 3% in states like Colorado and Louisiana to 13% in California. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — do not tax income at all, so residents pay only federal tax on savings interest.

Some states offer a small exemption for interest income, but it's usually modest. New York, for example, excludes the first $100 of interest income per person per year. Illinois excludes all interest and dividend income, making it one of the most savings-friendly states for tax purposes.

If you live in a city with a local income tax — Philadelphia, Columbus, Kansas City, and a handful of others — you may owe local tax on savings interest as well. This is typically 1% to 2% of your income and is collected through your employer or paid when you file your state return.

When you receive the Form 1099-INT and how to use it

Banks and credit unions send Form 1099-INT to customers who earned $10 or more in interest during the calendar year. You receive it by January 31 of the following year. The form shows the total interest earned in box 1, and any federal tax withheld in box 4 (though most savings accounts do not withhold).

You report the amount from box 1 on Schedule B (Interest and Ordinary Dividends) if you have more than $1,500 in interest income, or directly on line 1b of Form 1040 if you have less. If you have multiple savings accounts, you add up all the interest from all the 1099-INTs and report the total.

Keep your 1099-INT with your tax records. The IRS receives a copy, so the amount must match what you report on your return. If you lose the form, you can request a duplicate from your bank, usually within a few business days.

Tax-advantaged accounts that reduce or eliminate tax on interest

Regular savings accounts offer no tax break, but certain accounts do. A Roth IRA or Roth 401(k) allows you to earn interest and withdraw it tax-free in retirement, though you cannot withdraw the interest before age 59½ without penalty. A traditional IRA or 401(k) defers tax on interest until you withdraw the money in retirement, when you'll owe tax at your rate then.

A 529 college savings plan lets you earn interest tax-free if you use the money for may have access to education expenses. If you withdraw it for other purposes, you owe tax on the interest portion plus a 10% penalty.

A Coverdell Education Savings Account works similarly to a 529 but has lower contribution limits ($2,000 per year per child). Health Savings Accounts (HSAs) allow tax-free interest if you use withdrawals for medical expenses.

For most people with modest savings, the tax on interest is small enough that opening a tax-advantaged account is not worth the complexity. But if you have $100,000 or more in savings earning 4% or higher, the tax savings can be significant.

What happens if you don't report savings interest on your tax return

The IRS receives a copy of every 1099-INT your bank sends you. If you don't report the interest on your return, the IRS will notice the discrepancy and may send you a notice of underreported income. You'll owe the unpaid tax plus interest (currently around 8% annually) and potentially a penalty of 20% of the unpaid tax.

The IRS does not always catch small amounts of unreported interest when ready, but the longer you wait, the more interest and penalties accumulate. If you discover you missed reporting interest from a prior year, you can file an amended return using Form 1040-X. Filing an amendment voluntarily before the IRS contacts you usually results in lower penalties.

If you earned less than $600 in interest and your bank did not send a 1099-INT, you still owe tax on that interest, but the IRS is less likely to catch it. That does not mean you should skip reporting it — the safest approach is to report all interest income, regardless of the amount.

Planning ahead when you earn significant savings interest

If you know you'll earn substantial interest — say, $1,000 or more — consider setting aside money throughout the year to cover the tax bill. A rough estimate is to multiply your expected interest by your tax bracket. If you expect $2,000 in interest and you're in the 24% federal bracket plus a 6% state bracket, you'll owe roughly $600 in combined tax.

Some people make quarterly estimated tax payments if they have significant interest income and no employer withholding. You do this using Form 1040-ES and paying the IRS directly. This is more common for self-employed people, but it's an option if you have large interest income.

Another approach is to keep most of your money in a tax-advantaged account like an IRA or 401(k) and use a regular savings account only for emergency funds. This reduces the amount of interest you earn in a taxable account.

Frequently Asked Questions

Do I owe tax on savings interest if I earned less than $600?

Yes. The $600 threshold only determines whether your bank must send you a 1099-INT. You owe tax on all interest income, regardless of the amount. If you earned $200 in interest, you report it on your tax return and owe tax at your bracket rate.

What if my bank did not send me a 1099-INT but I earned interest?

Contact your bank and request a copy. Banks are required to send 1099-INTs for interest of $10 or more. If your bank cannot locate it, ask for a written statement of the interest you earned and report that amount on your return.

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

No. You report the full interest amount on your tax return. You cannot reduce it by fees. However, if you paid significant investment-related fees or advisory fees, you may be able to deduct them as miscellaneous itemized deductions, though this is subject to limitations.

Is interest from a money market account taxed differently than a savings account?

No. Money market accounts, savings accounts, and certificates of deposit are all taxed the same way — as ordinary income at your federal and state tax rates. The account type does not change the tax treatment.

Do I owe tax on interest if I reinvest it back into the account?

Yes. You owe tax on interest in the year it is earned, even if you do not withdraw it and let it sit in the account. The fact that you reinvest it does not defer the tax.
