Yes, you owe federal income tax on savings account interest

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 must report it on your tax return, and you owe federal income tax on the full amount. Your bank will send you a form showing how much interest you earned, and that number goes into your tax calculation.

The tax you owe depends on your overall income and tax bracket. Someone in the 22% bracket pays roughly 22 cents in federal tax for every dollar of interest earned. Someone in the 12% bracket pays roughly 12 cents. The rate is not fixed to the interest itself — it depends on your total income for the year.

State and local income taxes also explore in most states. If you live in a state with income tax, you will owe state tax on the interest as well. A few states — including Florida, Texas, and Wyoming — have no state income tax, so residents there owe only federal tax.

Key Takeaways

  • All savings account interest is taxable federal income, regardless of the amount, and must be reported on your tax return.
  • Your bank sends you a Form 1099-INT each January showing the interest you earned in the previous year.
  • You owe tax at your marginal tax rate — the rate that applies to your highest income — not a flat rate on interest alone.
  • Most states tax savings interest as income, but a handful of states do not, so check your state's rules.
  • Interest under $10 may not require a 1099-INT form, but you still owe tax on it if you report all income accurately.

When your bank sends you Form 1099-INT

In late January or early February, your bank mails or emails you a Form 1099-INT for the previous calendar year. This form lists the total interest you earned in that account. If you have multiple savings accounts at different banks, you will receive a separate 1099-INT from each one.

The form shows the interest amount in Box 1. That number is what you report to the IRS. You do not report each month's interest separately — the bank totals it for you.

If you earned less than $10 in interest at a particular bank, that bank may not send you a 1099-INT form. However, you still owe tax on that interest if you report your income completely. The threshold is a reporting requirement for the bank, not a tax threshold for you.

How the interest amount affects your tax bill

The tax you owe on interest depends on your tax bracket, not on the interest rate itself. If you earned $500 in interest and you are in the 22% federal tax bracket, you owe roughly $110 in federal tax on that interest. If you are in the 12% bracket, you owe roughly $60.

Your tax bracket is determined by your total income — wages, self-employment income, investment gains, and interest all add together. Adding $500 in interest might push you into a higher bracket, or it might stay within your current bracket. Either way, the interest is taxed at whatever rate applies to that portion of your income.

This is why high-yield savings accounts, which pay 4% to 5% annually, can create a larger tax bill than traditional savings accounts paying 0.01%. A $10,000 balance earning 5% generates $500 in taxable interest. The same balance at 0.01% generates $1 in taxable interest. Both are taxable, but the tax bill is very different.

State income tax on savings interest

Most states treat savings interest as ordinary income and tax it at your state income tax rate. If your state income tax rate is 5%, you owe roughly 5 cents in state tax for every dollar of interest earned, on top of federal tax.

A small number of states do not tax interest income at all. These include Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you owe only federal tax on your savings interest.

Some states have special rules for certain types of interest or for people over a certain age. For example, a few states exempt interest earned by retirees. Check your state's tax authority website or speak with a tax preparer if you are unsure whether your state taxes savings interest.

Reporting interest on your tax return

When you file your federal tax return, you report the interest from your 1099-INT forms on Schedule B (Interest and Ordinary Dividends) if you have more than $1,500 in interest and dividends combined. If you have $1,500 or less, you can report the interest directly on Form 1040 without using Schedule B.

The total interest from all your 1099-INT forms goes into one line on your return. You do not report each account separately — you add them all together and enter the total.

If you received a 1099-INT but the amount is wrong, contact your bank when ready. The bank can issue a corrected form. If you did not receive a 1099-INT but you earned interest, you still report that interest on your return based on your own records — the bank's failure to send the form does not erase the tax obligation.

Interest from money market accounts and certificates of deposit

Money market accounts and certificates of deposit (CDs) work the same way as savings accounts for tax purposes. The interest is taxable income, your bank sends you a 1099-INT, and you report it on your tax return.

With a CD, the bank reports the interest even if you do not withdraw it before maturity. You owe tax on the interest in the year it is credited to your account, not in the year you withdraw the money. This matters if you buy a CD in December and it matures in January — you report the interest on the tax return for the year the CD was credited, not the year you cashed it out.

Frequently Asked Questions

Do I owe taxes on interest if I did not withdraw the money?

Yes. The IRS taxes interest in the year it is credited to your account, whether you withdraw it or leave it to compound. Your bank reports the interest on the 1099-INT based on what was credited, not on what you withdrew.

What if I earned interest at a bank that did not send me a 1099-INT?

You still owe tax on it. Report the interest based on your own records — your bank statements or the interest shown in your online account. The bank's failure to send a form does not eliminate the tax obligation.

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

No. You report the gross interest amount shown on the 1099-INT. Fees are not deductible against interest income for most taxpayers. However, if you are self-employed or have significant investment expenses, you may be able to deduct certain costs — consult a tax preparer about your specific situation.

Is the interest taxed differently if it is in a joint account?

The bank reports the total interest on a 1099-INT. If the account is jointly owned, the bank may split the interest between the two owners on separate forms, or it may report all of it to one owner. You and the other owner must agree on how to split the income for tax purposes, and each person reports their share on their own return.

Do I owe taxes on interest earned in a savings account for a child?

Yes, but the child owes the tax, not the parent. The interest is reported on the child's tax return. If the child's income is below the filing threshold, no return is required, but if the child has other income or the interest exceeds the threshold, a return must be filed. Some parents use the "kiddie tax" rules to report the child's interest on the parent's return — consult a tax preparer about whether this applies to your situation.
