You must report all interest earned on a high yield savings account as taxable income, even if the bank doesn't send you a form

The IRS treats interest from a high yield savings account the same way it treats interest from any other savings account: as ordinary income. That means you owe federal income tax on every dollar of interest you earn, no matter how small the amount or which bank holds the account. The bank will send you a Form 1099-INT if your interest reaches $10 or more in a calendar year, but you must report the interest even if you don't receive a form.

Most high yield savings accounts earn between 4% and 5% APY right now, which means a $10,000 balance generates roughly $400 to $500 per year in taxable interest. That interest gets added to your other income and taxed at your ordinary income tax rate—not at a lower capital gains rate. If you have multiple savings accounts, CDs, or money market accounts, you add up all the interest from all of them and report the total.

Key Takeaways

  • You report high yield savings interest on your federal tax return even if you earn less than $10 and receive no Form 1099-INT from the bank.
  • The bank sends Form 1099-INT only when interest reaches $10 or more in a single calendar year, but you are responsible for reporting smaller amounts yourself.
  • Interest income is taxed at your ordinary income tax rate, which varies by your total income and filing status, not at a special rate.
  • You report the interest on Schedule 1 (Form 1040) or on the appropriate line of your tax return form, depending on which form you file.
  • If you have multiple accounts earning interest, add up all the interest from all accounts and report the combined total.

When the bank sends Form 1099-INT and what it means

Your bank will mail or email you a Form 1099-INT by January 31 of the year after you earn the interest. For example, interest you earn in 2024 appears on a 1099-INT you receive by January 31, 2025. The form shows your name, Social Security number, the bank's name and ID number, and the total interest paid to you during that calendar year.

The threshold for sending a 1099-INT is $10. If you earn $9.99 in interest, the bank is not required to send you a form. If you earn $10 or more, the bank must send one. You receive a copy for your records, and the bank sends a copy to the IRS. The IRS uses that copy to cross-check your tax return, so if you report a different amount than what appears on the 1099-INT, the IRS will notice.

Some banks send 1099-INT forms even when interest falls below $10, and some online banks allow you to download the form from your account dashboard before January 31. Check your bank's website or call customer service if you are unsure whether you will receive a form.

How to report interest if you receive a Form 1099-INT

If you file Form 1040 (the standard federal income tax form for individuals), you report the interest on Schedule 1, Part I, Line 8. Write the total amount of interest income from all sources—all your savings accounts, CDs, money market accounts, and any other interest-bearing accounts. If you use tax software like TurboTax, H&R Block, or TaxAct, the software will ask you for the amount and automatically place it in the correct location.

You do not need to attach the 1099-INT to your return, but you should keep it with your tax records for at least three years. If you file Form 1040-SR (for people age 65 and older), the interest goes on Schedule 1 in the same place. If you file a different form—such as Form 1040-NR if you are a nonresident alien—the location may differ; check the instructions for your specific form.

The interest amount from the 1099-INT flows into your adjusted gross income (AGI), which affects your tax bracket and may affect your may be able to access for certain tax deductions and credits. For that reason, even small amounts of interest can matter if you are close to an income threshold.

Reporting interest when you don't receive a Form 1099-INT

If your interest is less than $10, or if your bank fails to send a form for any reason, you are still responsible for reporting the interest. Calculate the total interest you earned by checking your account statements or logging into your online banking portal. Most banks show interest deposits separately or provide an annual interest summary.

Report the amount on Schedule 1, Line 8, just as you would if you had received a 1099-INT. Write "Interest income not reported on 1099-INT" or similar notation next to the amount if you want to explain why you are reporting interest without a form. The IRS does not require this notation, but it can help if your return is audited and the IRS asks why the amount differs from what they received from the bank.

If you have multiple accounts at different banks and only some of them send 1099-INT forms, add up all the interest from all the accounts—both the ones with forms and the ones without—and report the combined total.

How interest income affects your tax bill and deductions

Interest income is added to your wages, self-employment income, and any other income you earn, and the total is taxed at your ordinary income tax rate. If you are in the 22% tax bracket, each dollar of interest costs you roughly 22 cents in federal tax (before considering state and local taxes). If you are in the 12% bracket, it costs roughly 12 cents per dollar.

Interest income can also push you into a higher tax bracket. For example, if your wages put you near the top of the 12% bracket, an extra $500 in interest might move part of your income into the 22% bracket. Tax software calculates this automatically, but it is worth understanding that earning interest is not "assistance programs"—it increases your tax liability.

Interest income may also affect your may be able to access for certain deductions and credits. The Earned Income Tax Credit (EITC), the Child Tax Credit, and the Saver's Credit all have income limits. If interest pushes your income over the limit, you may lose part or all of a credit you would otherwise receive. Similarly, if you are taking the standard deduction, interest income does not change that; you still take the standard deduction amount for your filing status.

State and local taxes on savings account interest

Most states tax interest income the same way the federal government does: as ordinary income at your state income tax rate. If you live in a state with income tax and earn interest, you must report it on your state return as well as your federal return. A few states—including New Hampshire and Tennessee—do not tax interest income, so if you live in one of those states, you report the interest only to the federal government.

Some cities and counties also impose local income taxes. If you live in a place with local tax, check whether interest is taxable at the local level. Your state tax form or your city or county tax authority's website will clarify what is taxable in your area.

If you moved during the year, you may owe tax to two states. Most states have rules for part-year residents, and you report interest based on how many months you lived in each state. Tax software usually handles this, but if you moved, make sure to tell your tax software or tax preparer.

Frequently Asked Questions

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

Yes. The $10 threshold is only for when the bank must send you a Form 1099-INT. You are responsible for reporting all interest you earn, regardless of the amount. Check your account statements and report the total on your tax return.

What if my bank sent me a 1099-INT with the wrong amount?

Contact the bank and ask them to issue a corrected form (called an amended 1099-INT). Once you receive the corrected form, report the correct amount on your tax return. If the IRS has already received the incorrect form, the discrepancy may trigger a notice, but you can respond with the corrected 1099-INT as proof.

Can I deduct the taxes I pay on savings account interest?

No. Interest income is taxable, and you cannot deduct the tax you owe on it. You can deduct investment fees or advisory fees in some cases, but not the income tax itself. State and local taxes on interest may be deductible under the State and Local Tax (SALT) deduction, subject to a $10,000 annual cap.

Do I need to report interest from a joint account?

The bank reports the full interest amount on a single 1099-INT, usually in the name of the first account holder. If you and the other account holder file separate returns, you must decide how to split the interest between you. Many couples split it 50/50, but the split should match how you actually own the account. Consult a tax preparer if you are unsure how to divide it.

Is savings account interest taxed differently than investment income?

Yes. Savings account interest is taxed as ordinary income at your regular tax rate. Long-term capital gains and may have access to dividends are taxed at lower rates (0%, 15%, or 20%, depending on income). Savings account interest never qualifies for those lower rates, no matter how long you hold the account.
