You owe federal income tax on the interest your HYSA earns, and possibly state income tax too

Any interest your high yield savings account generates counts as taxable income. The bank or financial institution holding your account will report this interest to the IRS on a Form 1099-INT, and you must report it on your federal tax return. The interest is taxed at your ordinary income tax rate — the same rate as your salary or wages — not at a lower capital gains rate.

The amount of tax you owe depends on how much interest you earned and your total income for the year. If you earned $500 in interest and you're in the 22% federal tax bracket, you would owe roughly $110 in federal tax on that interest alone. State income tax, where it applies, works the same way: the interest is added to your other income and taxed at your state's ordinary rate.

You do not have to pay tax on the money you deposit into the account — only on the interest it earns. If you put $10,000 into a HYSA and it earns $200 in interest over a year, you owe tax only on the $200, not on the $10,000 principal.

Key Takeaways

  • Interest earned in a high yield savings account is taxed as ordinary income at your federal tax rate and your state's tax rate if your state has income tax.
  • The bank reports your interest earnings to the IRS on Form 1099-INT, which you receive by January 31 of the following year.
  • You report this interest on your federal tax return; if you don't receive a 1099-INT but earned interest, you still must report it.
  • The higher your HYSA interest rate, the more tax you will owe on the earnings, though the interest itself is still yours to keep after taxes.

When the bank sends you a 1099-INT form

If your HYSA earned $10 or more in interest during the calendar year, the bank must send you a Form 1099-INT by January 31 of the following year. This form shows the total interest paid to you and goes to the IRS at the same time. You use this form to fill out your tax return.

Some banks send the 1099-INT by mail; others make it available through your online account portal. Check your account settings or call the bank's customer service line to find out how yours will arrive. If you don't receive it by early February, contact the bank directly — you need it to file your return accurately.

If you earned less than $10 in interest, the bank is not required to send a 1099-INT, but you still owe tax on that interest. You will need to report it yourself on your return based on your account statements or the interest shown in your online banking portal.

How to report HYSA interest on your tax return

On your federal return, you report interest income on Schedule B (Interest and Ordinary Dividends) if you have more than $1,500 in interest and dividend income combined. If you have $1,500 or less, you can report the interest directly on Form 1040 (the main federal tax form) without filing Schedule B.

The line item on your return is straightforward: you enter the total interest from your 1099-INT (or your own calculation if you didn't receive one) on the interest income line. This amount is then added to your other income to determine your total taxable income for the year.

If you file your taxes using tax software, the program will walk you through entering this information. If you file by hand or with a tax professional, bring your 1099-INT or account statements showing the interest earned. State tax returns vary by state, but most ask you to report the same interest income on your state form as well.

The difference between federal and state taxes on HYSA interest

Federal tax applies to all U.S. residents and is calculated the same way everywhere. State income tax, however, varies. 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 federal tax on your HYSA interest but no state income tax.

In the other 41 states plus Washington, D.C., you owe both federal and state income tax on the interest. Your state tax rate may be higher or lower than your federal rate. For example, California's top state income tax rate is 13.3%, while some states charge 3% or less. The interest is taxed at your state's ordinary income rate, just as it is at the federal level.

If you move to a different state during the year, you may owe tax to both states on the interest earned while you lived in each one. Your tax software or a tax professional can help you sort this out if it applies to you.

How much interest triggers a tax bill

There is no minimum amount of interest that makes you owe tax. Even $1 in interest is technically taxable income. However, whether you actually owe federal income tax depends on your total income and your filing status.

For 2024, if you are a single filer under age 65, you do not have to file a federal return unless your total income is at least $14,600. If your only income is $500 in HYSA interest, you would not be required to file. However, if you have other income — from a job, for example — the HYSA interest is added to that total. If your job income plus HYSA interest exceeds the threshold for your filing status, you must file and report the interest.

These income thresholds change each year. The IRS publishes updated thresholds in early spring each year on its website. Even if you are not required to file, you may want to file anyway if you had taxes withheld from your paycheck, because you might receive a refund.

Whether you can deduct HYSA expenses or losses

You cannot deduct the cost of maintaining a HYSA, such as monthly fees (though most HYSAs charge no fees). You also cannot deduct losses if you close the account early and lose interest you had already earned, or if the bank fails and your balance exceeds the FDIC insurance limit of $250,000.

The only exception is if you have investment losses that offset investment gains in the same year — but a HYSA is not an investment account, so this does not explore. Interest from a HYSA is straightforward: you report what you earned, and you pay tax on it. There are no deductions to reduce the taxable amount.

If you are self-employed and use a HYSA as a business account, you may be able to deduct business expenses paid from it, but the interest itself is still taxable income to you personally.

Comparing HYSA taxes to other savings and investment accounts

A regular savings account at a traditional bank earns much less interest than a HYSA, so you owe less tax on the earnings. A money market account works similarly to a HYSA: interest is taxed as ordinary income. A certificate of deposit (CD) also generates taxable interest, reported on a 1099-INT.

A taxable brokerage account holding stocks or mutual funds may generate capital gains, which are often taxed at a lower rate than ordinary income. A Roth IRA or Roth 401(k) grows tax-free, and withdrawals in retirement are not taxed. A traditional IRA or 401(k) defers taxes until you withdraw the money in retirement. A 529 college savings plan grows tax-free if used for education expenses.

A HYSA offers no tax advantage — you pay ordinary income tax on the interest. The benefit of a HYSA is the higher interest rate itself, not tax savings. If you are looking to reduce taxes on savings, a tax-advantaged retirement account or education savings plan may serve you better, depending on your situation.

Frequently Asked Questions

Do I owe taxes if I haven't withdrawn the interest yet?

Yes. Tax is owed on interest the moment it is credited to your account, whether you withdraw it or leave it in the account. The IRS taxes the interest income in the year it is earned, not when you spend or move the money.

What happens if I don't report HYSA interest on my tax return?

The IRS receives a copy of your 1099-INT from the bank and will notice if your return does not match. You may face penalties, interest charges on the unpaid tax, and possible audit. It is simpler and cheaper to report the interest when you file.

Can I avoid taxes by keeping my HYSA balance under a certain amount?

No. Tax is based on the interest you earn, not on how much money is in the account. A $100,000 balance earning 4% interest generates $4,000 in taxable income, regardless of the account size. You owe tax on the earnings no matter what.

Is HYSA interest taxed differently if I'm retired?

No. Interest is taxed at your ordinary income rate whether you are working or retired. However, if your total income in retirement is lower than when you were working, you may be in a lower tax bracket, so the same interest would result in a smaller tax bill.

Do I need to make estimated tax payments on HYSA interest?

Only if you owe more than $1,000 in federal income tax for the year and did not have enough tax withheld from other income. Most people with HYSA interest do not need to make estimated payments, but self-employed people or those with large investment income should check IRS guidelines or consult a tax professional.
