High yield savings interest is taxed as ordinary income

Yes. The interest your high yield savings account earns is taxed as ordinary income at your federal tax rate, plus any state and local income tax that applies where you live. The bank does not withhold the tax automatically — you owe it when you file your tax return. The IRS treats savings interest the same way it treats wages or salary: it is income, and income is taxable.

The amount you owe depends on how much interest you earned and your total income for the year. If you earned $500 in interest and you are in the 22% federal tax bracket, you owe roughly $110 in federal tax on that interest alone. State tax, if your state has income tax, adds on top of that.

Your bank will send you a Form 1099-INT by January 31 each year if you earned $10 or more in interest during that tax year. You report the amount shown on that form on your tax return. If you earned less than $10, the bank may not send a form, but you still owe tax on the interest — you have to track it yourself.

Key Takeaways

  • Interest from a high yield savings account is taxed as ordinary income at your federal tax rate plus any state income tax.
  • Your bank sends you a Form 1099-INT by January 31 if you earned $10 or more in interest; you report this amount on your tax return.
  • The tax is not withheld automatically, so you owe it when you file — or you may owe estimated tax payments if the interest is large enough.
  • The higher your interest rate and account balance, the more tax you will owe on the earnings.

How the IRS knows about your interest

The bank reports your interest earnings to the IRS on Form 1099-INT. The IRS receives a copy of that same form, so they know how much interest you earned. If you do not report it on your tax return, the IRS will notice the mismatch and may send you a notice or bill you for the unpaid tax plus penalties and interest.

You cannot avoid this by not reporting the interest or by moving money between accounts. The IRS tracks interest by the account holder's Social Security number or tax ID, not by account number. Moving $50,000 from one high yield account to another does not erase the interest you earned in the first account.

When you owe estimated tax on savings interest

If you expect to owe $1,000 or more in federal income tax for the year (including tax on your savings interest), you may have to make estimated tax payments four times a year instead of waiting until April. This applies mainly to self-employed people, but it can also apply if you have a large amount of savings earning high interest.

For example: if you have $100,000 in a high yield savings account earning 4.5% APY, you will earn $4,500 in interest that year. If that pushes your total tax bill above $1,000, you owe estimated tax. The IRS charges a penalty if you do not pay estimated tax when you are supposed to, even if you end up paying all the tax by April 15.

You do not have to make estimated payments if your employer withholds enough tax from your paycheck to cover your total tax bill for the year, including the savings interest. Talk to a tax professional or use IRS Form 1040-ES to figure out whether you need to pay estimated tax.

State income tax on savings interest

Most states that have income tax also tax savings interest at your state tax rate. A few states do not tax interest income at all — as of now, that includes Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you owe only federal tax on your savings interest.

If you live in a state with income tax, you report the same interest amount on your state tax return that you reported to the IRS. Some states have different tax brackets or rates than the federal government, so your state tax bill may be higher or lower than your federal bill on the same interest income.

How to reduce the tax you owe on savings interest

You cannot avoid the tax, but you can reduce the amount of interest you earn — and therefore the tax you owe — by keeping less money in the high yield account. This is not usually a good trade-off: earning 4.5% interest and paying 22% tax on it still leaves you with a 3.5% after-tax return, which beats most other savings options.

If you are retired or have very low income, you may owe no federal income tax at all, even on savings interest. The standard deduction for 2024 is $14,600 for a single person and $29,200 for a married couple filing jointly. If your total income (including interest) is below that amount, you owe no federal tax. You may still owe state tax, depending on where you live.

Some people use tax-advantaged accounts like IRAs or 401(k)s to earn interest without paying tax on it each year. Interest earned inside these accounts is not taxed until you withdraw the money (or in some cases, never taxed at all). However, these accounts have contribution limits and withdrawal rules, so they are not a replacement for a regular savings account.

Tracking interest across multiple accounts

If you have high yield savings accounts at more than one bank, each bank sends you a separate Form 1099-INT. You add up all the interest from all the forms and report the total on your tax return. The IRS receives copies of all those forms too, so they know your total interest income.

Keep your own records of interest earned in case there is a discrepancy. If a bank reports the wrong amount on your 1099-INT, ask them to send you a corrected form (Form 1099-INT with a "corrected" box checked). Do not file your tax return until you have the corrected form, or the IRS will see a mismatch.

Frequently Asked Questions

Do I owe tax on interest if I earned less than $10?

Yes. The bank does not have to send you a Form 1099-INT if you earned less than $10, but you still owe tax on the interest. You have to report it yourself on your tax return. Keep your own records of the interest earned so you can report the correct amount.

What if I move money out of a high yield account before the year ends?

You still owe tax on all the interest you earned while the money was in the account, even if you moved it out in December. The interest is taxed in the year it was earned, not the year you withdraw the principal.

Can I deduct the tax I pay on savings interest?

No. Interest income is taxed, but the tax itself is not deductible. You cannot reduce your taxable income by the amount of tax you owe on the interest.

Is interest from a money market account taxed the same way?

Yes. Money market accounts, savings accounts, and certificates of deposit (CDs) are all taxed as ordinary income. The bank reports the interest on Form 1099-INT, and you report it on your tax return the same way.

What happens if I do not report the interest on my tax return?

The IRS will see the Form 1099-INT the bank sent them and will notice that you did not report it. They may send you a bill for the unpaid tax plus a penalty (usually 20% of the unpaid tax) and interest charges that accrue daily.
