Savings account interest counts as taxable income

Interest you earn from 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. Most banks and credit unions will send you a Form 1099-INT each January showing how much interest you earned the previous year, and you report that figure on your tax return.

The tax you owe depends on your total income and tax bracket for that year. If you earned $500 in savings interest and you're in the 22% tax bracket, you don't automatically owe $110—your tax rate applies to your total income, not to each source separately. But that $500 does push your overall income higher, which can affect your tax bill and sometimes trigger other tax consequences.

State and local income taxes also apply to savings interest in most places. If you live in a state with income tax, you'll owe tax there too. A handful of states—including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming—don't have state income tax, so residents there owe only federal tax on interest.

Key Takeaways

  • Banks report savings interest to the IRS on Form 1099-INT, and you must report it as income on your tax return.
  • The amount of tax you owe depends on your tax bracket and total income for the year, not a flat percentage of the interest.
  • You owe federal income tax on all savings interest, plus state and local income tax if your state has it.
  • Interest under $10 for the year may not require a 1099-INT form, but you still owe tax on it if you have other income.
  • High-yield savings accounts earn more interest, which means a larger tax bill—factor this in when comparing accounts.

When you receive the 1099-INT form

Your bank or credit union sends Form 1099-INT by January 31 each year for interest earned during the previous calendar year. You should receive one copy in the mail and the IRS receives another automatically. If you have accounts at multiple banks, you may receive several 1099-INT forms—one from each institution.

The form shows the total interest paid to you during the year. If you earned less than $10 in interest, the bank may not be required to send a 1099-INT, but you still owe tax on that interest if you have other income. Some banks voluntarily send forms for small amounts anyway.

If you don't receive a 1099-INT by early February, contact your bank directly. You'll need the information to file your return accurately, and the IRS already has a copy. Filing without reporting the interest when the IRS has a record of it creates a mismatch that can trigger an audit notice.

How to report interest on your tax return

When you file your federal income tax return, you report the interest income on Schedule B (Form 1040), which is for interest and dividend income. You list each 1099-INT you received and add up the total. That total goes on line 1b of Form 1040 as part of your total income.

If your total interest and dividends for the year is $1,500 or less, you can report the total directly on Form 1040 without filing Schedule B, though many people file it anyway for clarity. If you earned more than $1,500, Schedule B is required.

You report state and local interest income on your state tax return using the same figures. Most state forms have a line for interest income, and you attach a copy of your 1099-INT or list the amounts manually.

Interest that may not be taxable

Most savings account interest is fully taxable, but a few narrow exceptions exist. Interest from certain U.S. savings bonds (Series EE and I bonds) can be tax-free if you use the money for may have access to education expenses. Interest from bonds issued by some state and local governments is exempt from federal tax, though these are rarely held in regular savings accounts.

Interest earned in a Roth IRA or Roth 401(k) is not taxable when you withdraw it in retirement, because you already paid tax on the money you contributed. Interest in a traditional IRA or 401(k) is tax-deferred—you don't pay tax on it while it sits in the account, but you owe tax when you withdraw it later.

Interest in a 529 college savings plan is also tax-deferred at the federal level and often tax-free at the state level if used for may have access to education costs. These are specialized accounts, not regular savings accounts, and have their own rules about what counts as a may have access to use.

How high-yield savings accounts affect your tax bill

High-yield savings accounts earn significantly more interest than traditional savings accounts—sometimes 4% to 5% APY compared to 0.01% or less at major banks. That higher interest means a larger 1099-INT form and a bigger tax bill. If you have $50,000 in a high-yield account earning 4.5% APY, you'll earn roughly $2,250 in interest per year, all of which is taxable.

The tax on that interest depends on your bracket. In the 22% federal bracket, you'd owe about $495 in federal tax on that $2,250. Add state tax if applicable, and your actual after-tax return is lower than the advertised APY. This doesn't make high-yield accounts a bad choice—they still beat traditional savings accounts—but it's worth factoring into your decision.

Some people move money between accounts to manage their tax situation, but this doesn't reduce the tax you owe. Interest is taxable in the year it's earned, regardless of which account holds the money when you file your return.

What happens if you don't report the interest

The IRS receives a copy of every 1099-INT your bank sends. If you don't report the interest on your return, the IRS will notice the mismatch between what you reported and what the bank reported. This triggers a notice asking you to explain the difference or pay the tax you owe.

If you owe tax and don't pay it, you'll face penalties and interest charges on top of the original tax bill. The penalty is usually 20% of the unpaid tax, plus interest that compounds daily. Paying late is always more expensive than paying on time.

Intentionally hiding income is tax evasion, which is a crime. Accidentally forgetting to report interest is a mistake, and the IRS usually treats it as such if you correct it promptly. If you realize you missed interest income from a prior year, file an amended return (Form 1040-X) as soon as possible.

Frequently Asked Questions

Do I owe tax on interest if I earned less than $1,500?

Yes. The $1,500 threshold only determines whether you file Schedule B—it doesn't exempt you from tax. You owe tax on all interest income, no matter how small, if you have other income. If interest is your only income and it's under $13,850 (for 2023), you may not owe federal tax due to the standard deduction, but you should still report it.

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

No. You report the full interest amount shown on the 1099-INT. Fees are not deductible against interest income. However, if a bank charges you a fee and credits you interest in the same month, the net amount is what appears on your 1099-INT anyway.

What if I moved money between banks mid-year?

Each bank reports only the interest it paid you. If you earned $100 at Bank A and $50 at Bank B, you'll receive two 1099-INT forms totaling $150. You report both on your tax return. The timing of transfers doesn't change the tax—interest is taxable in the year it's earned.

Do I owe tax on interest if I'm a minor?

Yes, minors owe tax on interest income just like adults. A parent or guardian files the minor's tax return if the interest exceeds the filing threshold. Some interest can be reported on the parent's return under "kiddie tax" rules if the minor has very little income, but this is complex—consult a tax professional if applicable.

Is interest from a money market account taxable?

Yes. Money market accounts are savings accounts, and all interest from them is taxable income reported on a 1099-INT. The tax treatment is identical to a regular savings account.
