You pay income tax on savings account 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 tax bracket, not on how much interest you earned. If you earned $50 in interest and you're in the 22% tax bracket, you owe roughly $11 in federal tax on that interest.

Your bank will send you a Form 1099-INT each January if you earned $10 or more in interest during the previous year. This form lists the total interest paid to your account. You report this amount on your federal tax return, and most states also tax savings interest as ordinary income.

The tax is due when you file your return, usually by April 15. You don't pay it upfront — the bank doesn't withhold it automatically the way an employer withholds income tax from your paycheck. That means if you earn interest and don't set money aside, you could owe tax you're not prepared to pay.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your federal tax bracket rate, whether that's 10%, 12%, 22%, or higher.
  • Your bank sends Form 1099-INT if you earned $10 or more in interest, and you must report this on your tax return.
  • Most states tax savings interest as income, so you may owe both federal and state tax on the same interest earnings.
  • The bank does not withhold tax automatically, so you need to plan for the tax bill when you file in April.

How your tax bracket determines what you owe

Your tax bracket is the percentage of your income that goes to federal tax. For 2024, the brackets range from 10% to 37%, depending on how much total income you have. If your total income (wages, interest, investment gains, and other sources combined) puts you in the 22% bracket, then your savings interest is also taxed at 22%.

This matters because interest doesn't get its own special rate — it stacks on top of your other income. If you earn $50,000 in wages and $500 in savings interest, the IRS sees $50,500 in total income and taxes all of it according to your bracket. The interest doesn't push you into a higher bracket unless your total income crosses a threshold.

You can find the 2024 tax brackets on the IRS website or on your tax software. The brackets change each year, so check the current year's rates when you file.

State income tax on savings interest

Most states tax savings interest as ordinary income, meaning you owe state tax in addition to federal tax. The state rate varies — it might be 3%, 5%, 8%, or higher depending on where you live and your income level. A few states have no income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming), so residents of those states owe only federal tax on interest.

If you live in a state with income tax, you'll report the same interest amount on your state return as you did on your federal return. Your state tax software or form will ask for this information, usually pulling it from the same Form 1099-INT your bank sent you.

Some states offer small breaks for interest earned on certain savings products or for savers over a certain age, but these are rare and usually apply only to very small amounts. Check your state's tax authority website if you think you might may have access to.

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

Your bank mails Form 1099-INT by January 31 each year. It shows the total interest paid to your account during the previous calendar year. If you have multiple savings accounts at different banks, you'll receive a separate 1099-INT from each one. You need to add up all the interest from all your forms and report the total on your tax return.

Keep the 1099-INT with your tax records. You don't mail it to the IRS — your bank sends a copy directly to the IRS. But you need it to fill out your return accurately, and the IRS may ask for it if they audit your return.

If you earned less than $10 in interest, your bank may not send you a 1099-INT, but you still owe tax on that interest if you file a return. You'll need to track it yourself or ask your bank for a statement showing the interest paid.

How to report interest on your tax return

On your federal return, you report savings interest on Schedule B (if you have other investment income) or directly on Form 1040 (if interest is your only investment income). The exact line depends on your tax software or form, but the process is straightforward: enter the total interest from all your 1099-INT forms.

Your tax software will usually walk you through this step by step. If you file by hand, the Form 1040 instructions explain where the interest line is. State returns follow a similar process — you report the same interest amount on your state form.

If you earned interest but didn't receive a 1099-INT (because it was under $10 or your bank didn't send one), you still report it. Write the amount on the appropriate line and note that you didn't receive a form.

Strategies to reduce taxes on savings interest

High-yield savings accounts pay more interest than traditional savings accounts, but the interest is still fully taxable. Moving money to a higher-yield account doesn't reduce your tax bill — it increases the interest you earn and therefore increases the tax you owe. This is still usually worth doing because the extra interest outweighs the extra tax.

Certificates of deposit (CDs) work the same way: the interest is taxable income. Some people use CDs as part of a tax strategy by timing when they mature, but the interest itself is always taxable.

If you have very little income and your total is below the standard deduction for your filing status, you may not owe federal tax even if you earned interest. The standard deduction for 2024 is $14,600 for single filers and $29,200 for married filing jointly. If your total income is below that, you may not have a federal tax bill, though you should still file if you had taxes withheld.

Tax-advantaged accounts like IRAs and 401(k)s do shelter interest from immediate taxation, but these accounts have contribution limits and withdrawal rules. They're not designed just for interest — they're retirement savings vehicles with specific rules about when you can access the money.

What happens if you don't report interest income

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 when they match your return against the forms they received. This can trigger a notice asking you to explain the difference, and you may owe the tax plus penalties and interest.

Even small amounts matter. If you earned $50 in interest and didn't report it, the IRS will eventually catch it. It's not worth the risk or the hassle of dealing with a notice later.

If you made an honest mistake and forgot to report interest, you can file an amended return (Form 1040-X) to correct it. This is much simpler than waiting for the IRS to contact you.

Frequently Asked Questions

Do I owe tax on interest if I earned less than $10?

Yes. Your bank doesn't have to send you a 1099-INT for amounts under $10, but you still owe tax on that interest. You'll need to track it yourself or ask your bank for a statement. Report it on your return even without a form.

Can I deduct savings account fees from my interest income?

No. You report the full interest amount as income. Savings account fees are not deductible on your personal tax return. Some business accounts may have different rules, but for personal savings accounts, the interest is taxable and the fees are not deductible.

What if I moved money between accounts during the year?

Moving money doesn't affect the tax. You owe tax on the interest earned, regardless of how many times you transferred the money or which account it was in. The 1099-INT will show the total interest from that account for the year.

Is interest taxed differently if I'm retired?

No. Interest is taxed at your ordinary rate whether you're working or retired. However, if your total income in retirement is low enough, you may not owe federal tax. Some states offer small tax breaks for retirees, but these are uncommon and usually apply only to specific types of income.

Do I report interest earned in a joint account?

Yes. If you own a joint account, you and the other owner may each receive a 1099-INT, or the bank may issue one in the name of the first owner listed. Check with your bank about how they report joint account interest. You'll need to coordinate with the other owner to make sure you're both reporting the correct amount on your returns.
