You must report the interest your high yield savings account earns, even if the bank doesn't send you a form

The IRS requires you to report all interest income, including money earned in a high yield savings account. Banks send a 1099-INT form to you and the IRS when your interest reaches $10 or more in a calendar year. If your account earned less than $10, the bank won't send a form—but you still owe tax on that interest. The IRS knows about your account because banks report it to them whether or not they send you paperwork.

Whether you file taxes at all depends on your total income and filing status, not on whether you have a savings account. If you're required to file a tax return for other reasons (wages, self-employment, or other income), you must include the savings interest. If you're not required to file, you don't have to—but you may want to anyway if taxes were withheld from your paychecks, because filing gets you a refund.

Key Takeaways

  • Banks report interest of $10 or more to the IRS on a 1099-INT form, and you must report it on your tax return even if you don't receive the form.
  • Interest under $10 is not reported by the bank, but you still owe tax on it if your total income requires you to file.
  • You report savings interest on Schedule 1 (Form 1040) or Schedule B if you have more than $1,500 in total interest income.
  • High yield savings accounts typically earn enough interest to trigger the $10 reporting threshold within a few months, depending on your balance and the APY.
  • If you don't file taxes because your income is below the filing threshold, you don't have to report the savings interest, but the IRS still has a record of it.

When the bank sends you a 1099-INT form

Your bank will mail or email you a 1099-INT by January 31 of the year after you earned the interest. The form shows the total interest paid to your account during the previous calendar year. You receive Copy B; the bank sends Copy A to the IRS. If you have accounts at multiple banks, you may receive several 1099-INT forms—one from each institution.

The $10 threshold is per bank, not per account. If you have two savings accounts at the same bank and earn $6 in one and $5 in the other, the bank will send you a 1099-INT because the combined interest is $11. If you have $6 at one bank and $5 at another, neither bank sends a form, but you still report both amounts.

The form arrives even if you closed the account during the year. The bank reports interest earned up to the date you closed it. If you opened an account late in the year and earned very little interest, you still receive the form if the total reaches $10.

Interest below $10 and unreported earnings

When your account earns less than $10 in a year, the bank does not send a 1099-INT. This does not mean the interest is tax-free or that you shouldn't report it. You are still required to report it on your tax return if you file one. The IRS does not receive a copy from the bank, but that does not change your obligation to report it.

Many people with small savings balances or accounts opened late in the year fall into this category. If you have $500 in a high yield savings account earning 4% APY, you earn roughly $20 per year—well above $10. But if you opened the account in November, you might earn only $1.67 that year, which means no form arrives. You still report it.

Where to report the interest on your tax return

If your total interest income from all sources is $1,500 or less, you report it on Schedule 1 (Form 1040), line 8. You list the total amount and the source (your bank's name). You do not need to attach the 1099-INT to your return, but keep it for your records.

If your total interest income exceeds $1,500, you must use Schedule B (Interest and Ordinary Dividends) instead. Schedule B requires you to list each source of interest separately. You still attach Schedule B to Form 1040, not the 1099-INT itself.

If you file electronically, the software walks you through these sections and calculates the total for you. If you file by paper, the IRS instructions for Form 1040 show exactly where each amount goes. The interest from your high yield savings account is treated the same as interest from a regular savings account, money market account, or CD.

What happens if you don't report the interest

The IRS matches the 1099-INT the bank sent them against your tax return. If the form shows $50 in interest but your return shows $0, the IRS will notice. They may send you a notice asking you to explain the discrepancy or file an amended return. If you simply forgot to report it, you can file an amended return (Form 1040-X) and pay the tax owed plus interest.

Penalties for underreporting interest are typically 20% of the underpaid tax if the error was not due to reasonable cause. If you can show you made a good-faith mistake, the IRS may waive the penalty. The tax itself, however, is always owed, plus interest that accrues from the original due date.

If you intentionally hide interest income, that is tax evasion, which carries criminal penalties. In practice, most people who miss small amounts of interest income simply amend their return when they realize the mistake. The IRS is more interested in collecting the tax than in punishing honest errors.

Filing requirements based on your total income

Whether you must file a tax return at all depends on your gross income and filing status, not on whether you have a savings account. For 2024, a single person under 65 must file if their gross income is $14,600 or more. If you're married filing jointly and both under 65, the threshold is $29,200. These thresholds change each year.

Gross income includes wages, self-employment income, interest, dividends, and most other sources. If your only income is $500 in savings interest and you have no other income, you are not required to file. However, if you earned $14,200 in wages plus $500 in savings interest, your total is $14,700, and you must file.

Even if you're not required to file, you may want to. If your employer withheld taxes from your paychecks, filing a return gets you a refund. If you had no withholding and owe tax on the interest, you can file to pay what you owe and avoid penalties.

High yield savings and tax planning

High yield savings accounts currently earn between 4% and 5.35% APY, depending on the bank and current rates. On a $10,000 balance, that's roughly $400 to $535 per year in interest. On a $50,000 balance, it's $2,000 to $2,675. All of this is taxable income in the year you earn it, regardless of whether you withdraw the money.

The interest is taxed as ordinary income at your marginal tax rate. If you're in the 22% federal tax bracket, earning $500 in interest costs you roughly $110 in federal tax. State income tax may apply as well, depending on where you live. Some states do not tax interest income, while others tax it at the same rate as wages.

If you're saving for a specific goal and want to minimize taxes, you might consider keeping some money in a regular savings account (which earns less interest but is still taxable) or in a Roth IRA or other tax-advantaged account if you're may be able to access. However, the tax on high yield savings interest is usually worth paying because the interest rate is so much higher than traditional savings accounts.

Frequently Asked Questions

Do I have to report savings interest if I didn't receive a 1099-INT form?

Yes. If your account earned less than $10, the bank won't send a form, but you still report the interest on your tax return if you file one. The IRS has a record of your account and expects you to report all interest income.

What if I have multiple high yield savings accounts at different banks?

Each bank sends a separate 1099-INT if the interest reaches $10. You report the total interest from all accounts on your tax return. If one account earned $8 and another earned $7, neither bank sends a form, but you report both amounts if you file.

Can I deduct fees or losses from my savings interest?

No. You report the gross interest the bank paid you, not the net amount after fees. Savings account fees are not deductible. You report the full interest amount on your return.

What if I moved money between banks during the year?

Moving money between your own accounts is not taxable. Only the interest earned is taxable. Each bank reports interest earned in their account during the time you held it. If you moved $10,000 from Bank A to Bank B in June, Bank A reports interest earned January through June, and Bank B reports interest earned June through December.

Do I need to keep the 1099-INT after I file my taxes?

Keep it for at least three years in case the IRS asks questions about your return. After that, you can discard it. The IRS has a copy, so you don't need to send it with your return or keep it forever, but holding onto it protects you if there's a discrepancy.
