Yes, you must report the interest your high yield savings account earns

The IRS requires you to report all interest income, including interest from high yield savings accounts. Your bank will send you a Form 1099-INT in January showing how much interest you earned during the previous year. You then report that amount on your tax return, even if the interest is small.

The threshold for receiving a 1099-INT varies by bank. Most banks issue the form if you earned $10 or more in interest during the year, though some issue it at $1. Even if your bank does not send you a form, you still owe tax on the interest—the form is just documentation. The IRS has records of your account through the bank's reporting, so omitting it creates a mismatch they will catch.

Interest is taxed as ordinary income at your regular tax rate, not at the capital gains rate. This means a high yield savings account earning 4% to 5% APY will generate taxable income you cannot avoid by simply not reporting it.

Key Takeaways

  • Your bank reports interest income to the IRS on Form 1099-INT, and you must include that amount on your tax return regardless of whether you receive the form.
  • Interest from high yield savings accounts is taxed as ordinary income at your full tax rate, not at a lower capital gains rate.
  • The IRS knows about your interest earnings through bank reporting, so failing to report it will trigger a notice if your return does not match their records.
  • You can reduce taxable interest by holding savings in a tax-advantaged account like a Roth IRA or 529 plan, though contribution limits apply.

When your bank sends Form 1099-INT

Banks mail Form 1099-INT by January 31 each year. The form shows the total interest you earned in the previous calendar year. If you have multiple high yield savings accounts, each bank that paid you $10 or more in interest will send its own form.

You receive a copy for your records and a copy goes to the IRS. The IRS matches the 1099-INT to your tax return to verify you reported the income. If your return shows no interest income but the bank reported it, the IRS will send you a notice asking why.

Some banks issue 1099-INT forms at lower thresholds—$1 or $5—even though the IRS minimum is $10. Check your bank's website or call to find out their threshold. Either way, you owe tax on all interest, not just the amount shown on a form.

How interest income affects your tax bill

Interest is added to your other income and taxed at your marginal rate. If you earn $50,000 in wages and $1,000 in interest, your taxable income is $51,000. The interest does not get a special low rate—it is treated the same as wages.

The tax impact depends on your total income and filing status. A single filer in 2024 pays 10% federal tax on the first $11,600 of income, 12% on income from $11,601 to $47,150, and higher rates above that. Interest pushes you into a higher bracket if it crosses a threshold. A married couple filing jointly has higher brackets before the rate increases.

State income tax also applies in most states. If you live in a state with income tax, the interest is taxable there too. A few states—Florida, Texas, Wyoming, and others—have no state income tax, so residents only owe federal tax on interest.

Reporting interest on your tax return

You report interest income on Schedule B (Interest and Ordinary Dividends) if your interest exceeds $1,500 for the year. If your interest is $1,500 or less and you have no other investment income, you can report it directly on Form 1040, line 2b, without filing Schedule B.

List each account separately on Schedule B if you are required to file it. Include the bank name, account number (last four digits), and the interest amount from the 1099-INT. Add up all interest and transfer the total to Form 1040.

If you file electronically using tax software, the software will prompt you to enter interest income and place it in the correct location automatically. If you file by paper, follow the instructions on Form 1040 and Schedule B.

Strategies to reduce taxable interest

One way to earn interest without reporting it is to hold savings in a Roth IRA. Interest earned inside a Roth IRA is not taxed, and you do not report it on your return. However, Roth IRAs have annual contribution limits—$7,000 per year for most people in 2024, or $8,000 if you are 50 or older. You can only contribute if you have earned income.

A 529 education savings plan also shields interest from federal tax if the money is used for may have access to education expenses. Interest grows tax-free and withdrawals for tuition, fees, room and board, and books are not taxed. Non-may have access to withdrawals are taxed on the earnings portion.

A Health Savings Account (HSA) works similarly if you are enrolled in a high-deductible health plan. Interest in an HSA is not taxed if withdrawn for medical expenses. If you withdraw for other reasons after age 65, the interest is taxed but not penalized.

For most people, these accounts fill up quickly relative to how much savings they have. Once you hit the contribution limit, any additional savings must go into a regular high yield savings account, and that interest is taxable.

What happens if you do not report interest income

The IRS will eventually notice. When your bank reports interest on Form 1099-INT and your tax return does not show that income, the IRS computer system flags the mismatch. You will receive a CP2000 notice proposing additional tax, interest, and penalties.

The penalty for underreporting income is usually 20% of the underpaid tax. Interest accrues on the unpaid balance at a rate set quarterly by the IRS—currently around 8% annually. If the IRS determines the underreporting was intentional, the penalty can be as high as 75%.

You have the right to respond to a CP2000 notice within 30 days. If you agree, you pay the additional tax plus interest and penalties. If you disagree, you can provide documentation or request Appeals consideration. Most people who receive these notices end up paying because the 1099-INT is clear documentation of the income.

Frequently Asked Questions

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

Yes. The $10 threshold only determines whether your bank sends you a 1099-INT form. You owe tax on all interest income, regardless of amount. If you earned $3 in interest and your bank did not send a form, you still report it on your return.

What if I have a high yield savings account at an online bank that does not send forms?

All banks report interest to the IRS, even if they do not send you a paper form. Check your online account or contact the bank to find your interest earnings. The IRS has the same information the bank reported, so you must include it on your return.

Can I deduct expenses to offset the interest income?

No. Interest income is reported in full, and you cannot deduct the cost of maintaining the account or fees you paid. You report gross interest as shown on the 1099-INT, not net interest after expenses.

Does interest from a joint account get split between both owners?

The bank reports the full interest amount to the IRS. If the account is held jointly, you and the other owner must decide how to split the income for tax purposes. This is usually done based on each person's ownership percentage or as agreed between you. Each person reports their share on their own return.

What if I moved money between accounts and earned interest twice?

Each bank reports interest separately based on what you held in their account. If you moved $10,000 from Bank A to Bank B mid-year, Bank A reports interest on the average balance it held, and Bank B reports interest on what it held. You report both amounts. There is no double-tax issue because each bank only reports interest on money that was actually in their account.
