Interest from a high yield savings account counts as ordinary income on your federal tax return

The interest your bank pays you on a high yield savings account is taxable income. The IRS treats it the same way it treats wages or salary — you owe federal income tax on every dollar of interest you earn, at your regular tax rate. If you earn $500 in interest over a year and you're in the 22% tax bracket, you'll owe roughly $110 in federal tax on that interest alone.

Your bank will send you a 1099-INT form in January or early February if you earned $10 or more in interest during the previous year. You report the amount shown on that form on your tax return. Some states also tax interest income, so you may owe state tax as well.

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 — so you need to account for it yourself when you calculate what you owe or when you estimate your tax liability for the year.

Key Takeaways

  • Interest earned in a high yield savings account is taxed as ordinary income at your federal tax rate, regardless of how much you earn.
  • Your bank sends a 1099-INT form if you earned $10 or more in interest; you report this amount on your tax return.
  • The tax is not withheld automatically, so you are responsible for setting aside money or adjusting your withholding to cover what you'll owe.
  • Many states tax interest income in addition to federal tax, so check your state's rules.
  • Interest earned in a traditional IRA or 401(k) is not taxed until you withdraw it; interest in a Roth IRA is never taxed.

How the IRS counts interest as income

The IRS considers interest taxable income in the year you earn it, even if you don't withdraw the money. If your account earns $200 in interest on December 31 and you leave it sitting there, you still owe tax on that $200 in the year it was credited to your account. This is called the accrual method of accounting.

Your tax bracket determines how much you pay. If you're single and earn $47,150 to $100,525 in total income for 2024, you're in the 22% federal bracket. Interest is added to your other income, so $500 in interest could push you into a higher bracket or increase the tax you owe at your current rate. The exact amount depends on your total income for the year.

You cannot deduct the interest you earn as a loss or offset it against other income. It's simply added to your taxable income.

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

Your bank issues a 1099-INT form if you earned $10 or more in interest during the calendar year. The form arrives by January 31 of the following year. It shows your name, Social Security number, the bank's name, and the total interest paid.

You receive one copy and the IRS receives another. When you file your tax return, you report the amount from Box 1 of the 1099-INT on Schedule 1 (Form 1040), line 8b. If you use tax software, you enter the amount and it flows to the right place automatically. If you file by hand, you add it to your other income on your return.

Keep your 1099-INT with your tax records for at least three years. If the IRS audits you, they will compare the 1099-INT they received from the bank with what you reported on your return.

State income tax on interest

Most states tax interest income the same way the federal government does. If you live in a state with an income tax, you will owe state tax on your interest in addition to federal tax. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — do not have a state income tax, so residents owe only federal tax.

New Hampshire and Tennessee tax only interest and dividend income, not wages. If you live in one of those states, you still owe tax on your high yield savings interest.

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

How much interest triggers a 1099-INT

Your bank must send you a 1099-INT if you earned $10 or more in interest during the year. This is a low threshold — a high yield savings account earning 4% to 5% APY will hit $10 in interest on a balance of just $200 to $250.

Even if you don't receive a 1099-INT because you earned less than $10, you still owe tax on whatever interest you did earn. The $10 threshold is only about whether the bank sends the form, not about whether the income is taxable.

If you have multiple savings accounts at different banks, each bank sends its own 1099-INT. You report the total interest from all accounts on your tax return.

Interest in retirement accounts is handled differently

If you hold a high yield savings account inside a traditional IRA or 401(k), the interest is not taxed while it sits in the account. You pay tax only when you withdraw the money, and then the entire withdrawal is taxed as ordinary income at your regular rate.

If you hold a high yield savings account inside a Roth IRA, the interest is never taxed — not while it's in the account and not when you withdraw it in retirement. This is one reason Roth accounts are valuable for long-term savers.

Regular taxable savings accounts (not inside an IRA or 401(k)) have no such protection. Interest is taxed every year, regardless of whether you touch the money.

What to do if you owe tax on interest but didn't plan for it

If you earned significant interest and didn't set aside money for taxes, you have a few options. You can pay the tax when you file your return using a check, credit card, or electronic transfer through the IRS website. If you can't pay in full, you can set up a payment plan with the IRS — they charge interest and a fee, but you can spread the payment over several months.

For the following year, you can adjust your W-4 form at work to have more tax withheld from your paycheck, which reduces the amount you owe at tax time. If you're self-employed or don't have a job, you can make quarterly estimated tax payments to the IRS.

If you expect to earn a lot of interest in the future, consider moving some money to a tax-advantaged account like a Roth IRA, where interest is never taxed. You can contribute up to $7,000 per year to a Roth IRA if you're under 50 (or $8,000 if you're 50 or older) in 2024.

Frequently Asked Questions

Do I owe tax on interest if I don't withdraw the money?

Yes. The IRS taxes interest in the year you earn it, whether you withdraw it or leave it in the account. If your account credits $300 in interest on December 15, you owe tax on that $300 even if you never touch it.

What if I earned less than $10 in interest?

You still owe tax on it, but your bank won't send a 1099-INT. You report the interest on your tax return based on your account statements or a letter from the bank. The $10 threshold is only about whether the bank is required to send the form.

Can I deduct the interest I earn as a business expense?

No. Interest income cannot be deducted. It's added to your taxable income, not subtracted from it. You can only deduct interest you pay (like mortgage interest or student loan interest), not interest you receive.

Will my bank withhold taxes from my interest?

No. Banks do not automatically withhold federal or state income tax from interest payments. You are responsible for paying the tax when you file your return or through quarterly estimated payments.

Is interest taxed differently if I'm retired?

No. Interest is taxed at your regular rate regardless of your age or employment status. However, if you're over 65, you get a larger standard deduction on your tax return, which may reduce the amount of interest that's actually taxable.
