Interest income is taxable income, just like wages

The interest your savings account earns counts as taxable income to the IRS. You owe federal income tax on it at your ordinary tax rate — the same rate you pay on salary or other income. Most savings accounts also trigger state income tax on that interest, depending on where you live.

The amount you owe depends on two things: how much interest you earned and your tax bracket. A person in the 22% federal tax bracket who earned $500 in savings interest owes roughly $110 in federal tax on that amount. Someone in the 12% bracket owes roughly $60 on the same $500.

Banks report this interest to the IRS on a Form 1099-INT if you earned $10 or more in interest during the year. You receive a copy, and so does the IRS. You report the amount on your tax return whether or not you receive the form.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your federal tax rate, which ranges from 10% to 37% depending on your income level.
  • Banks report interest of $10 or more on Form 1099-INT, which you must include on your tax return.
  • Most states tax savings interest as well, though a few states do not tax any interest income.
  • The tax is owed in the year the interest is credited to your account, even if you do not withdraw the money.
  • High-yield savings accounts earn more interest, which means you owe more tax — but the after-tax return is usually still better than a traditional savings account.

How the IRS knows about your interest

Your bank tracks every cent of interest credited to your account and reports the total to the IRS each January. If you have multiple savings accounts, each bank sends its own Form 1099-INT. The forms arrive by January 31 so you can include the amounts when you file your return.

You are required to report this interest even if you never receive a 1099-INT form — for instance, if you earned $8 in interest at one bank and $6 at another, neither bank sends a form, but you still owe tax on the $14 total. The IRS cross-checks 1099 forms against tax returns, so underreporting or omitting interest income creates a mismatch that triggers a notice.

Your tax bracket determines what you actually owe

The federal tax rate on interest income is not a flat percentage. It depends on your total income for the year and your filing status. For 2024, a single person with $47,000 in income falls into the 22% tax bracket, while someone with $100,000 in income is in the 24% bracket.

This means the same $500 in savings interest costs different people different amounts. A person in the 10% bracket owes $50 in federal tax on that $500. A person in the 37% bracket (the highest) owes $185. Your tax software or a tax professional can calculate your exact bracket based on your full income picture.

Interest income also affects whether you owe the Net Investment Income Tax, a 3.8% additional tax that applies to certain investment income if your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). Savings account interest counts toward this threshold.

State taxes on savings interest vary widely

Most states tax savings interest as ordinary income, using rates that range from roughly 1% to 13% depending on the state. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — do not tax interest income at all. New Hampshire and Tennessee tax only interest and dividend income, not wages.

If you live in a state that taxes interest, you report the same amount you reported to the IRS on your state return. Some states allow you to exclude a small amount of interest income (usually $100 to $1,200 per year for retirees), but most do not.

If you moved during the year or work in a state different from where you live, state tax on interest becomes more complex. You may owe tax to both states, or one state may allow a credit for taxes paid to the other. A tax professional can sort this out if your situation is complicated.

When the tax is owed and how to pay it

You owe tax on interest in the year it is credited to your account, not the year you withdraw the money. If your bank credits $200 in interest on December 31, 2024, you owe tax on that $200 in 2024, even if you do not touch the account until 2025.

The tax is not withheld automatically from your account. You pay it when you file your return or through quarterly estimated tax payments if you owe a large amount. If you expect to owe more than $1,000 in federal tax for the year, the IRS may require you to make quarterly payments rather than waiting until April.

If you have too much tax withheld from other income (like wages), you may get a refund that covers the tax on your interest. If you do not have enough withheld, you owe the difference when you file.

High-yield savings accounts and the tax trade-off

A high-yield savings account earns 4% to 5% annual interest, while a traditional savings account at a big bank earns 0.01% to 0.05%. The higher rate means more interest — and more tax. But the after-tax return is usually still much better.

Say you have $10,000 in a savings account and you are in the 22% federal tax bracket plus a 5% state tax bracket (27% combined). A traditional account earning 0.02% generates $2 in interest and costs you about $0.54 in tax. A high-yield account earning 4.5% generates $450 in interest and costs you about $121.50 in tax. Your after-tax gain is $328.50 instead of $1.46.

The tax on high-yield interest is real, but it does not erase the advantage. You still come out far ahead. The key is understanding that the advertised rate is before tax, not after.

What to do if you earned very little interest

If you earned less than $10, your bank does not send a 1099-INT form. You still owe tax on the interest, but the amount is so small that it usually does not change your tax bill significantly. Report it on your return if you itemize or if you are required to report all income.

If you have multiple accounts and the total interest across all of them is less than $10, you still report the combined total. Keep your own records of interest earned — your bank statements show it, even if no form arrives.

Frequently Asked Questions

Do I owe taxes on interest if I do not withdraw the money?

Yes. The tax is owed in the year the interest is credited to your account, regardless of whether you withdraw it, transfer it, or leave it sitting there. The IRS taxes the income when you earn it, not when you spend it.

What if I earned interest at multiple banks?

Each bank reports its interest separately on its own 1099-INT form. You add all the amounts together and report the total on your tax return. If the combined total is less than $10, no bank sends a form, but you still report it.

Can I deduct savings account interest as a loss?

No. Interest income is taxable; you cannot deduct it. You can deduct investment losses in certain situations, but savings account interest is not an investment loss — it is income.

Does a high-yield savings account cost more in taxes than a regular savings account?

Yes, because you earn more interest and therefore owe more tax. But the after-tax return is still much better. A 4.5% high-yield account earning $450 and costing $121 in tax leaves you $329 ahead of a 0.02% account earning $2 and costing $0.54 in tax.

What if my interest income pushes me into a higher tax bracket?

Interest income is added to your other income to determine your tax bracket. If your wages plus interest income crosses a bracket threshold, the interest portion is taxed at the higher rate. This is rare with savings interest alone, but it can happen if you have other investment income as well.
