You owe federal income tax on the interest your high yield savings account earns, and possibly state income tax too

The interest your account generates counts as ordinary income on your federal tax return. The IRS treats it the same way it treats wages or salary — you report it, and you pay tax on it at your regular income tax rate. If your account earned $500 in interest over the year, that $500 is added to your total taxable income for the year.

Your bank will send you a Form 1099-INT by January 31 each year if your account earned $10 or more in interest during that tax year. You use this form to report the interest on your federal tax return. If you earned less than $10, the bank may not send the form, but you still owe tax on that interest — you have to report it yourself.

Most states also tax savings account interest as income, at whatever rate your state uses. A few states — including Pennsylvania, Illinois, and Mississippi — do not tax interest income at all. If you live in one of those states, you skip state tax on your savings interest but still owe federal tax.

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 you a Form 1099-INT by January 31 if you earned $10 or more in interest during the tax year.
  • Most states tax savings interest as income, but a handful of states do not — check your state's rules.
  • You pay tax on the interest in the year you earn it, not when you withdraw the money.

When you owe tax on the interest

You owe tax on interest in the year you earn it, not in the year you withdraw it. If your account earned $200 in interest during 2024, you report that $200 on your 2024 tax return — even if you leave the money in the account and do not touch it until 2025.

This matters because high yield savings accounts often compound interest daily or monthly. That means interest gets added to your balance regularly, and then you earn interest on that interest. All of it counts as taxable income in the year it is earned, even the portion that came from compounding.

How the tax amount changes based on your income bracket

The tax you pay on savings interest depends on your total income for the year, not just the interest itself. If you earn $35,000 in wages and $500 in interest, your taxable income is $35,500. That $500 in interest gets taxed at whatever marginal rate applies to your income bracket.

Federal tax brackets vary by filing status and change each year. For 2024, a single filer in the 22% bracket pays 22 cents in federal tax for every dollar of interest earned. Someone in the 12% bracket pays 12 cents per dollar. The higher your total income, the higher the rate applied to your interest.

State tax rates work the same way — your interest is added to your income and taxed at your state's rate for that bracket. If you live in a state with a flat income tax (like Illinois at 4.95%), you pay that rate on all your interest. If your state uses progressive brackets, the rate depends on your total income.

Reporting interest on your tax return

When you file your federal return, you report the interest from your Form 1099-INT on Schedule 1 (Other Income), which feeds into your Form 1040. If you use tax software, it usually walks you through entering the 1099-INT information. If you file by hand or with a tax preparer, give them the form and they will enter it in the right place.

If you have multiple savings accounts at different banks, each bank sends its own 1099-INT. You add up all the interest from all the forms and report the total on your return. The IRS cross-checks the 1099-INT forms they receive from banks against what you report, so make sure the amounts match.

For state taxes, you usually report the same interest amount on your state return. Some states have their own forms or schedules for interest income, but most just ask you to add it to your total income. Check your state's tax instructions or ask your preparer.

What happens if you do not report the interest

If you do not report interest income on your return, the IRS will eventually notice. Banks report 1099-INT forms to the IRS, and the IRS matches those reports against filed returns. If your return shows no interest income but the bank reported interest in your name, the IRS will send you a notice asking for the missing tax.

You will owe the tax you should have paid, plus interest on that unpaid tax (currently around 8% per year), and possibly a penalty for underpayment. The penalty is usually 20% of the unpaid tax, though it can be lower if you have a reasonable cause for the mistake. Reporting the interest when you file the first time costs you nothing extra and avoids this problem entirely.

Strategies to reduce taxes on savings interest

You cannot avoid tax on interest, but you can reduce the amount you owe by earning less interest — which sounds obvious but matters in practice. If you have money you do not need for several years, a certificate of deposit (CD) or Treasury bond might lock in a rate that is higher than a savings account but still taxed the same way. The higher rate means more interest, which means more tax, so this does not actually help.

What does help is keeping money in tax-advantaged accounts if you have them. Interest earned inside a Roth IRA, 401(k), or 529 education savings plan is not taxed in the year it is earned — you pay tax later (or never, in the case of a Roth). If you have room to contribute to these accounts, that is a better place for money you are saving long-term than a regular high yield savings account.

For money you need to keep accessible, a high yield savings account is still the right choice despite the tax. The interest rate is high enough that even after paying tax, you come out ahead of a regular savings account or money market account. You just need to budget for the tax when you file.

Frequently Asked Questions

Do I have to report interest if I earned less than $10?

Yes. Your bank does not have to send a 1099-INT if you earned less than $10, but you still owe tax on that interest. You report it yourself on your tax return. The IRS does not have a minimum threshold for reporting interest income.

What if I move money between high yield savings accounts during the year?

Moving money does not change the tax. You owe tax on all interest earned in the account during the year, regardless of when you move the balance. Each bank reports the interest earned while the money was with them on their own 1099-INT.

Can I deduct the taxes I pay on savings interest?

No. Interest income is added to your taxable income, and you pay tax on it at your regular rate. You cannot deduct the tax itself as an expense. The only way to reduce the tax is to earn less interest or move money to a tax-advantaged account.

Do I owe estimated tax payments if my interest is high?

Only if your total tax liability for the year is high enough. If you expect to owe more than $1,000 in federal tax after accounting for withholding, you may need to make quarterly estimated tax payments. Most people with savings interest do not hit this threshold, but if you have other income or large interest earnings, ask a tax preparer.

What if the 1099-INT has the wrong amount?

Contact your bank and ask them to issue a corrected form. They will send you a corrected 1099-INT and also send a corrected version to the IRS. Do this as soon as you notice the error — do not file your return with the wrong amount and hope the IRS does not notice.
