The IRS taxes your HYSA interest as ordinary income at your regular tax rate

Interest earned in a high-yield savings account is taxed the same way as wages or salary — at whatever federal tax bracket you fall into. If you earn $500 in interest and you're in the 22% tax bracket, you owe roughly $110 in federal tax on that interest. The bank doesn't automatically withhold this tax; you report it yourself when you file your return.

Your state may also tax this interest. Most states treat savings account interest as taxable income, though a few (like Illinois and Mississippi) exempt it for residents over a certain age. The tax rate varies by state and by your income level within that state.

The bank will send you a 1099-INT form by January 31 each year showing how much interest you earned. You use this form to report the income on your tax return. If you earned more than $10 in interest during the year, the bank is required to send you this form.

Key Takeaways

  • Interest from a high-yield savings account is taxed as ordinary income at your federal tax rate, not at a lower capital gains rate.
  • Your bank sends you a 1099-INT form by January 31 showing the interest you earned, which you report on your tax return.
  • Most states tax savings account interest as regular income, though rates and exemptions vary by state and age.
  • You are responsible for paying this tax when you file your return — the bank does not withhold it automatically.
  • The more interest you earn, the higher your total tax bill, because the interest pushes you into a higher bracket or adds to your existing bracket.

Federal tax brackets and how interest moves you up

Your interest income is added to your other income for the year, and the total determines which federal tax bracket applies. If you earn $50,000 in wages and $2,000 in interest, the IRS treats you as earning $52,000 total. That extra $2,000 may push you into a higher bracket, meaning you pay a higher rate on that portion.

For 2024, federal tax brackets range from 10% to 37% depending on your filing status and total income. A single filer earning $47,150 to $100,525 falls in the 22% bracket. If that person earns $3,000 in interest, roughly $660 of it goes to federal tax. The exact amount depends on whether the interest pushes them into the next bracket.

If you're retired or have low income from other sources, your interest might fall into the 10% or 12% bracket, meaning your tax bill is smaller. If you're a high earner, the same interest could be taxed at 32% or higher.

State taxes on savings account interest

State income tax on interest varies widely. Most states tax it at the same rate as federal income tax — meaning your state rate plus your federal rate. Some states have flat income tax rates (like Colorado at 4.4% or Illinois at 4.95%), while others use brackets similar to federal brackets.

A few states do not tax interest income at all. Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax. If you live in one of these states, you owe only federal tax on your interest.

Some states offer exemptions for older residents. Illinois, Mississippi, and a few others exempt interest income for people over 65 or 67. Check your state's tax authority website or a tax professional to confirm your state's rules.

When you owe estimated taxes on interest

If you expect to owe $1,000 or more in federal tax for the year (including tax on your interest), the IRS may require you to pay estimated quarterly taxes rather than waiting until April. This applies mainly to self-employed people and retirees with significant investment income, but it can apply to anyone with large interest earnings.

Estimated taxes are due on April 15, June 15, September 15, and January 15 of the following year. You calculate what you expect to owe and send it in four payments. If you don't pay estimated tax and you owe more than $1,000 at tax time, you may owe a penalty.

Most people with a regular job and a savings account do not need to worry about estimated taxes — their employer withholds enough from their paycheck to cover the interest tax. But if you're retired, self-employed, or have very high interest income, ask a tax professional whether you need to pay quarterly.

How to report interest on your tax return

When you file your federal return, you report the interest from your 1099-INT on Schedule 1 (Form 1040), line 1b. You then transfer that amount to your main Form 1040. If you use tax software, it usually walks you through entering the 1099-INT information, and the software calculates your tax automatically.

If you have multiple savings accounts at different banks, each bank sends a separate 1099-INT. You add up all the interest from all your accounts and report the total on your return.

State returns work similarly — you report the same interest income on your state return, and your state calculates tax based on its own brackets and rates. Some states allow you to deduct federal tax paid, which lowers your state tax bill slightly.

Strategies to reduce taxes on interest income

You cannot avoid taxes on interest, but you can reduce the amount you earn in taxable interest. One option is to keep some money in a Roth IRA or 401(k), where interest and growth are not taxed each year. Money in these accounts grows tax-free until you withdraw it (and Roth withdrawals may never be taxed).

Another option is to hold some money in a regular savings account or money market account instead of a high-yield account. You'll earn less interest, which means less tax. This only makes sense if you're in a very high tax bracket and the interest you'd earn in a HYSA would push you significantly higher.

If you're married and file jointly, you and your spouse can each open a HYSA and split your savings. This doesn't reduce total tax, but it may help if one spouse has much higher income — the interest on the lower-earning spouse's account is taxed at a lower rate.

For most people, the simplest approach is to keep money in a high-yield account and report the interest on your tax return. The interest you earn usually outweighs the tax you owe.

What happens if you don't report interest income

The IRS receives a copy of every 1099-INT your bank sends you. If you don't report the interest on your return, the IRS will notice the mismatch and may send you a notice asking for the missing tax plus penalties and interest. The penalty for not reporting income is typically 20% of the unpaid tax, plus interest that compounds daily.

If the IRS determines you intentionally hid income, the penalty can be higher — up to 75% of the unpaid tax. Criminal prosecution for tax evasion is rare for small amounts, but it is possible.

The safest and simplest approach is to report all interest income, even if the amount is small. The cost of filing correctly is zero; the cost of not filing can be substantial.

Frequently Asked Questions

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

The bank is not required to send you a 1099-INT if you earned less than $10 in interest. However, you are still legally required to report all interest income on your tax return, even if it's $1. In practice, the IRS rarely pursues very small amounts, but technically you should report it.

Can I deduct savings account fees from my interest income?

No. You report the full interest amount on your return; you cannot subtract fees or other expenses. However, if you paid investment advisory fees or tax preparation fees related to managing your savings, those may be deductible in limited situations. Consult a tax professional about your specific circumstances.

What if I moved money between accounts during the year?

Moving money between your own accounts does not create taxable income. Only the interest the bank pays you is taxable. If you transferred $10,000 from a regular savings account to a high-yield account, that transfer itself is not taxed — only the interest you earn on that $10,000 is taxed.

Is interest from a money market account taxed differently?

No. Interest from a money market account is taxed the same way as interest from a high-yield savings account — as ordinary income at your regular tax rate. The bank sends you a 1099-INT, and you report it on your return the same way.

Do I owe taxes on interest if I'm not a U.S. citizen?

Yes. If you have a U.S. bank account and earn interest, you owe U.S. tax on that interest regardless of citizenship status. Non-citizens may have different filing requirements or withholding rules depending on visa status. Consult a tax professional familiar with non-citizen taxation.
