You report HYSA interest as ordinary income on your federal tax return, and you may owe taxes on it even if the account earned less than $600

The interest your high yield savings account earns counts as taxable income. The IRS treats it the same way it treats wages or salary — you owe federal income tax on the full amount, at your regular tax rate. Your bank will send you a form called a 1099-INT (Interest Income) by January 31 each year if you earned $10 or more in interest during that year, though some banks report even smaller amounts.

You do not pay taxes directly to your bank. Instead, you report the interest income when you file your federal tax return, usually by April 15. If you owe taxes on the interest, you pay the IRS, not the bank. State income tax works the same way — you report the interest to your state and pay any state tax owed, unless you live in a state with no income tax.

The amount you owe depends on your total income and your tax bracket. Someone in the 22% tax bracket who earned $500 in HYSA interest would owe roughly $110 in federal tax. Someone in the 12% bracket would owe roughly $60. The exact amount varies based on your filing status, other income, and deductions.

Key Takeaways

  • Your bank sends a 1099-INT form by January 31 if you earned $10 or more in interest during the year, and you must report this interest on your federal tax return.
  • You pay tax on HYSA interest at your regular income tax rate, which means the tax owed depends on your total income and tax bracket, not a flat rate.
  • The IRS requires you to report interest income even if your bank does not send a 1099-INT, so keep your own records if the amount is under $10.
  • State income tax applies to HYSA interest in most states, though a handful of states do not tax income at all.
  • You can reduce taxable interest by holding the account in a tax-advantaged account like a Roth IRA or 529 plan, where interest grows tax-free.

When your bank sends the 1099-INT form

Your bank mails or makes available a 1099-INT by January 31 each year if you earned $10 or more in interest during the previous calendar year. The form shows the total interest paid to you. You receive one 1099-INT per account at each bank — if you have multiple HYSA accounts at different banks, each bank sends its own form.

Some banks report interest even if you earned less than $10, so check your account statements or online banking portal in late January. If you earned interest but did not receive a 1099-INT, you still must report it to the IRS. Keep your own records — your monthly statements or year-end interest summary from the bank — so you can report the correct amount.

If you earned interest at multiple banks, you add up all the 1099-INT amounts and report the total on your tax return. The IRS receives a copy of each 1099-INT your bank sends, so they know how much interest you earned. Failing to report it creates a mismatch between what you reported and what the IRS has on file, which can trigger an audit notice.

How to report HYSA interest on your tax return

You report HYSA interest on Schedule B (Interest and Ordinary Dividends) if you use the long form (Form 1040), or on the simpler Form 1040-SR if you are 65 or older. If your total interest and dividends for the year are $1,500 or less, you can report the amount directly on Form 1040 without filing Schedule B — the IRS allows this shortcut.

If you use tax software (TurboTax, H&R Block, TaxAct, or similar), the software walks you through entering the 1099-INT information. You enter the bank name, the interest amount from the 1099-INT, and the software places it in the correct location on your return. If you file by hand or work with a tax preparer, give them a copy of each 1099-INT you received.

The interest amount goes into the "Interest Income" line of your return. It is added to your other income (wages, self-employment income, capital gains, and so on) to calculate your total taxable income. From there, the IRS applies your tax bracket to determine how much federal tax you owe.

What your tax bracket means for HYSA interest

Your tax bracket is the percentage rate applied to your income. In 2024, federal tax brackets range from 10% to 37%, depending on your total income and filing status. The interest you earn is taxed at your marginal rate — the rate that applies to your last dollar of income.

If you are single and earned $50,000 in wages plus $500 in HYSA interest, that $500 is taxed at whatever bracket your $50,500 total falls into. For 2024, a single filer with $50,500 in income is in the 22% bracket, so you would owe roughly $110 in federal tax on the $500 interest. A single filer with $20,000 in income plus $500 in interest would be in the 12% bracket and would owe roughly $60.

You cannot reduce the interest amount itself — you report what you earned. But you can reduce your overall taxable income through deductions (standard or itemized), which lowers your tax bracket and the amount of tax owed on the interest. Some people also use tax-advantaged accounts to avoid taxes on interest altogether, which is covered in the next section.

Using tax-advantaged accounts to avoid taxes on HYSA interest

If you hold a high yield savings account inside a Roth IRA, the interest you earn is not taxed. The same applies to a Roth 401(k), a 529 education savings plan, or a Coverdell ESA (education savings account). Interest earned inside these accounts grows tax-free, and you do not report it on your tax return.

The catch is that these accounts have contribution limits and rules about when you can withdraw the money. A Roth IRA allows you to contribute up to $7,000 per year (or $8,000 if you are 50 or older in 2024), and you cannot withdraw earnings before age 59½ without a penalty — though there are exceptions for first-time home purchases and education expenses. A 529 plan is designed for education expenses; withdrawals for non-education purposes trigger taxes and a 10% penalty on the earnings portion.

If you have money you do not need for retirement or education, a regular taxable HYSA is your only option, and you will owe taxes on the interest. But if you have retirement savings or education savings goals, moving some money into a Roth IRA or 529 with a high yield savings option can eliminate the tax on that interest.

State income tax on HYSA interest

Most states tax interest income the same way the federal government does — as ordinary income at your state tax rate. Your state tax rate varies by state and by income level, ranging from roughly 1% to 13% depending on where you live.

Nine states have no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only interest and dividends, not wages). If you live in one of these states, you owe no state tax on HYSA interest, though you still owe federal tax.

If you live in a state with income tax, you report the same interest amount to your state that you reported to the IRS. Some states use the federal 1099-INT directly; others require you to file a separate state return. Check your state's tax authority website or ask a tax preparer about your state's rules.

What happens if you do not report HYSA interest

If you do not report interest income, the IRS will likely catch it. Your bank sends a copy of the 1099-INT to the IRS, and the IRS computer system matches it against your tax return. If you reported $0 in interest but your bank reported $500, the IRS will send you a notice asking for the missing tax plus interest and penalties.

The penalty for underreporting income is typically 20% of the underpaid tax, plus interest on the unpaid amount. If the underreporting was unintentional, you can file an amended return (Form 1040-X) and pay the tax owed; the IRS may waive the penalty if you have a reasonable cause. If the IRS determines the underreporting was intentional, penalties can be higher.

The safest approach is to report all interest income, even if the amount is small. If you earned interest but did not receive a 1099-INT, report it anyway based on your bank statements. The cost of reporting is zero; the cost of not reporting can be substantial.

Frequently Asked Questions

Do I have to report HYSA interest if I earned less than $600?

Yes. The IRS requires you to report all interest income, regardless of amount. Banks are only required to send a 1099-INT if you earned $10 or more, but you must report smaller amounts based on your own records. The IRS does not have a threshold below which interest is tax-free.

Can I deduct HYSA interest as a business expense?

No. Interest earned on a personal savings account is income, not a deductible expense. If you are self-employed and hold business funds in a HYSA, the interest is still taxable income to you personally. You cannot write it off as a business cost.

What if I moved money between banks during the year?

Each bank reports only the interest it paid you. If you moved $10,000 from Bank A to Bank B in June, Bank A reports the interest it paid for January through May, and Bank B reports the interest it paid for June through December. You add both 1099-INT forms together and report the total on your tax return.

Do I owe taxes on HYSA interest if I am retired?

Yes, if you earned interest, you owe taxes on it at your tax rate. Being retired does not exempt you from reporting interest income. However, retirees may have lower overall income, which could put them in a lower tax bracket, meaning less tax owed on the interest. Some retirees also may have access to for the Earned Income Tax Credit or other credits that reduce their tax bill.

Can I claim HYSA interest as a loss if the account earned very little?

No. Interest income cannot be negative or claimed as a loss. You report whatever interest you earned, even if it is $1. You cannot offset it against other income or claim it as a deduction.
