Yes, you pay federal income tax on HYSA interest, and possibly state and local tax too

Interest earned in a high yield savings account is taxed as ordinary income by the IRS. That means the interest rate your bank pays you — whether it's 4.5% or 5.35% — gets added to your other income on your tax return and taxed at your regular income tax rate. If you earn $500 in interest over a year and you're in the 22% tax bracket, you owe roughly $110 in federal tax on that interest alone.

Your bank will send you a Form 1099-INT in January or February showing how much interest you earned during the previous year. You report that amount on your federal tax return. Most states also tax interest income the same way, though a handful — including Illinois, Mississippi, and Tennessee — do not tax interest at all. Some cities impose local income tax on interest as well, depending on where you live.

The tax is owed whether or not your bank withholds it. Many banks do not automatically withhold taxes from HYSA interest, which means you may owe the full amount when you file. Some banks offer the option to have taxes withheld, but you have to request it.

Key Takeaways

  • Interest earned in a high yield savings account counts as ordinary income and is taxed at your regular federal income tax rate.
  • Your bank reports the interest on Form 1099-INT, which you receive by early February and must report on your tax return.
  • Most states tax HYSA interest the same way the federal government does, though Illinois, Mississippi, and Tennessee do not tax interest income.
  • You can request that your bank withhold taxes from your interest payments, but most do not do this automatically.
  • The amount of tax you owe depends on your total income for the year and which tax bracket you fall into.

How the IRS treats HYSA interest differently from other savings

The IRS does not distinguish between interest from a high yield savings account and interest from a regular savings account earning 0.01%. Both are taxed as ordinary income. The difference is that a HYSA pays you more interest, so you owe more tax on it.

Interest is treated differently from capital gains, which are taxed at lower rates if you hold an investment for more than a year. Interest is also different from may have access to dividends. Because HYSA interest is ordinary income, it is taxed at the same rate as your wages or salary. If you earn $60,000 in salary and $1,000 in HYSA interest, the IRS treats that $1,000 the same way it treats your salary.

When you receive the Form 1099-INT and what to do with it

Banks mail or make available Form 1099-INT by January 31 each year. This form shows the total interest you earned during the previous calendar year. If you have multiple HYSAs at different banks, you will receive a separate 1099-INT from each bank.

You report the amount shown on the 1099-INT on your federal tax return. If you file using tax software, you enter the amount into the interest income section. If you file by hand, you report it on Schedule B (if you have more than $1,500 in interest income) or directly on Form 1040. You must report all interest income even if your bank did not withhold taxes.

Keep your 1099-INT forms for your records. You do not send them to the IRS — the bank sends a copy to the IRS separately. But if the IRS later questions your return, you will need the form to show where the income came from.

State and local taxes on HYSA interest

Most states tax interest income at your regular state income tax rate, the same way the federal government does. If your state has a 5% income tax rate, you will owe roughly 5% of your HYSA interest to your state. A few states have lower rates for interest income, but most do not.

Three states — Illinois, Mississippi, and Tennessee — do not tax interest income at all. If you live in one of these states, you owe no state tax on your HYSA interest, though you still owe federal tax. Some other states exempt interest earned on certain types of accounts or by certain groups of people (such as retirees), but these exemptions are narrow and usually explore only to specific account types.

Some cities impose local income tax on residents. New York City, for example, taxes interest income. If you live in a city with local income tax, you may owe local tax on your HYSA interest in addition to federal and state tax. Check your city or county tax authority's website to find out whether you owe local tax.

How tax withholding works and whether to request it

Tax withholding means your bank holds back a portion of your interest and sends it to the IRS on your behalf. Most banks do not withhold taxes from HYSA interest automatically. If you want your bank to withhold taxes, you usually have to request it by filling out a Form W-9 or a similar form provided by your bank.

Withholding is optional. Some people request it because they want to avoid owing a large amount when they file their tax return. Others skip it because they prefer to keep the full interest amount in their account and pay the tax when they file. There is no tax advantage to either choice — you owe the same total tax either way.

If you do request withholding, your bank will withhold at a flat rate, usually 10% or 24% depending on the bank and your instructions. This flat rate may not match your actual tax rate. If you are in a high tax bracket, 24% withholding might not be enough. If you are in a low tax bracket, 24% might be too much, and you will get a refund when you file. You can adjust your withholding request at any time by contacting your bank.

How much tax you actually owe on your interest

The amount of tax you owe on HYSA interest depends on your total income for the year and your tax bracket. If you earn $50,000 in salary and $1,000 in HYSA interest, your taxable income is $51,000. The tax on that extra $1,000 is calculated using your marginal tax rate — the rate that applies to your highest dollars of income.

For 2024, the federal tax brackets are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. If you are single and earn $50,000, you are in the 22% bracket, so the extra $1,000 in interest is taxed at 22%, meaning you owe $220 in federal tax on that interest. If you are single and earn $200,000, you are in the 35% bracket, so the same $1,000 in interest costs you $350 in federal tax.

Your state and local taxes work the same way. The higher your total income, the higher the tax rate applied to your HYSA interest. This is why two people earning the same amount of interest can owe very different amounts of tax.

Tax-advantaged alternatives to regular HYSAs

If you want to earn interest without paying tax on it every year, you can hold savings in certain tax-advantaged accounts. A traditional IRA or 401(k) allows your savings to grow tax-free until you withdraw the money in retirement. A Roth IRA lets your savings grow tax-free and allows you to withdraw the money tax-free in retirement, as long as you follow the rules.

These accounts have contribution limits and withdrawal rules that regular HYSAs do not have. A traditional IRA has a contribution limit of $7,000 per year (or $8,000 if you are 50 or older). You cannot withdraw money before age 59½ without paying a penalty, with some exceptions. A Roth IRA has the same contribution limit but allows you to withdraw your contributions (not the earnings) at any time without penalty.

A Health Savings Account (HSA) is another option if you have a high-deductible health plan. You can contribute up to $4,150 per year (or $8,300 for a family), and the money grows tax-free as long as you use it for medical expenses. If you use it for non-medical expenses after age 65, you pay income tax but no penalty.

These accounts are not replacements for an HYSA because they have rules about when and how you can use the money. But if you have money you will not need for several years, they can be a way to earn interest without paying tax on it annually.

Frequently Asked Questions

Do I have to report HYSA interest if I earned less than $1,500?

Yes. The IRS requires you to report all interest income, no matter how small. The $1,500 threshold only determines whether you use Schedule B or report it directly on your tax form — it does not determine whether you have to report it at all. If your bank sends you a 1099-INT, you must report the amount shown.

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

The IRS receives a copy of your 1099-INT from your bank. If you do not report the interest, the IRS will likely notice the discrepancy and may send you a notice asking for the missing income and back taxes. You may also owe penalties and interest on the unpaid tax. Reporting the interest is simpler and cheaper than dealing with an IRS notice later.

Can I deduct HYSA interest as a loss on my taxes?

No. Interest income is taxable, but you cannot deduct it as a loss. You report the full amount of interest earned as income on your tax return. The only way to reduce the tax is to have the interest income offset by other deductions or losses, such as capital losses from investments.

Do I owe taxes on HYSA interest if I'm a dependent?

Yes, but the amount of tax depends on your total income. If you are a dependent with no other income and earn less than the standard deduction (which is $14,600 for 2024 if you are single), you may not owe federal income tax. However, you still have to file a return to report the interest if your bank sent you a 1099-INT. Your parents cannot claim the interest as their income.

If I move to a state with no income tax, do I owe back taxes on old HYSA interest?

No. You owe state tax on interest based on where you lived when you earned it. If you earned interest while living in a state with income tax, you owe that state's tax on that interest, even if you move away later. You do not owe tax to your new state on interest you earned before you moved there.
