You pay income tax on savings account interest, not on the money you deposit

The interest your bank pays you on a savings account is taxed as ordinary income by the federal government and, in most states, by your state too. The money you put into the account itself is never taxed — that's money you already paid tax on when you earned it. Only the interest counts as new income.

How much tax you owe depends on your total income for the year and your tax bracket. A person in the 22% federal tax bracket who earns $500 in savings interest will owe roughly $110 in federal tax on that interest alone. Someone in the 12% bracket owes roughly $60 on the same $500. The exact amount also depends on whether you have other income, deductions, and credits that year.

Your bank reports the 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 must report it on your tax return, even if the bank didn't send you a form. The IRS cross-checks what you report against what the bank reported.

Key Takeaways

  • Interest earned on savings accounts is taxed as ordinary income at your federal tax bracket rate, plus state income tax in most states.
  • Banks report interest of $10 or more on Form 1099-INT, which you must include on your tax return.
  • High-yield savings accounts earn more interest but are taxed the same way as regular savings accounts.
  • You can reduce taxable interest by holding money in tax-advantaged accounts like IRAs or 529 plans, depending on your situation.
  • Interest is reported and taxed in the year you earn it, not when you withdraw the money.

How your tax bracket determines what you owe

Federal income tax is progressive, meaning the rate increases as your income goes up. In 2024, the brackets range from 10% for the lowest earners to 37% for the highest. Your savings interest is added to your other income — wages, self-employment income, investment gains — and taxed at whatever bracket your total income falls into.

If you earn $50,000 in wages and $300 in savings interest, the IRS treats you as earning $50,300. That $300 is taxed at the marginal rate for someone in your bracket, not at a flat rate. For most people, that means the interest is taxed at the same rate as the last dollars of your paycheck.

State income tax works similarly in the 41 states that have it. A few states — Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — do not tax income at all, so residents of those states owe only federal tax on savings interest. New Hampshire and Tennessee tax only interest and dividends, not wages.

Why high-yield savings accounts don't change the tax picture

A high-yield savings account earns more interest than a traditional savings account — sometimes 4% to 5% annually, compared to 0.01% or less at many big banks. But the tax treatment is identical. All that extra interest is still reported on Form 1099-INT and taxed as ordinary income.

The advantage of a high-yield account is that you earn more money to begin with, even after taxes. If you earn $500 in interest instead of $50, you owe more tax, but you keep more money overall. The tax rate itself does not change based on where the interest comes from.

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

Your bank mails or emails Form 1099-INT by January 31 each year if you earned $10 or more in interest during the previous year. The form shows the total interest paid to you and your account number. You receive Copy B, and the bank sends Copy A to the IRS.

You must report this interest on your tax return, typically on Schedule 1 (Form 1040) under "Interest" income. If you use tax software, you enter the amount from the 1099-INT and the software places it in the correct spot. If you file by hand or with a tax professional, give them the form or the amount.

If you earned less than $10 in interest, the bank may not send a 1099-INT, but you still owe tax on that interest and must report it. Keep your bank statements as proof of how much you earned.

Tax-advantaged accounts that shield savings interest from tax

Certain accounts let you earn interest without paying federal income tax on it, at least for a time. A traditional IRA or 401(k) grows tax-free until you withdraw money in retirement. A Roth IRA grows tax-free permanently if you follow the rules. A 529 college savings plan grows tax-free if the money is used for education expenses.

These accounts have contribution limits and withdrawal rules. For 2024, you can contribute up to $7,000 per year to an IRA (or $8,000 if you're 50 or older), and up to $23,500 to a 401(k) (or $31,000 if you're 50 or older). A 529 plan has no annual limit, but contributions may be subject to gift tax rules depending on the amount and your relationship to the beneficiary.

If you have high savings and want to reduce the tax on interest, a tax professional can help you figure out which accounts make sense for your situation. The rules are complex and depend on your income, age, and goals.

How to report interest if you don't receive a 1099-INT

If you earned interest but the bank did not send you a Form 1099-INT — either because you earned less than $10 or because the bank made an error — you still report it on your tax return. Use your bank statements to calculate the total interest for the year.

Write the amount on Schedule 1 under "Interest" income, just as you would if you had a 1099-INT. The IRS may not catch the omission if the amount is small, but you are legally required to report all income, and underreporting can trigger an audit or penalty if discovered later.

If you think the bank made a mistake and did not send a 1099-INT when it should have, contact the bank and ask for a corrected form. Banks can issue amended 1099-INTs if they discover an error within a certain time frame.

What happens if your interest income is very high

If you earn more than $1,500 in interest and dividends combined in a year, you must file Schedule B (Form 1040) in addition to Schedule 1. This form asks for details about each account and the interest from each one. It is mainly a tracking tool for the IRS.

High interest income can also trigger the Net Investment Income Tax, a 3.8% additional tax that applies to certain high-income earners. This tax kicks in if your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly) and you have net investment income. Interest counts as investment income for this purpose.

If you have substantial savings or investments, a tax professional can help you understand whether this tax applies to you and whether strategies like tax-loss harvesting or account restructuring might help.

Frequently Asked Questions

Do I owe tax on savings interest if I don't withdraw the money?

Yes. Interest is taxed in the year you earn it, not when you withdraw it. If your account earned $200 in interest in 2024, you owe tax on that $200 in 2024, even if you leave the money in the account and never touch it.

What if I have multiple savings accounts at different banks?

Each bank reports interest separately on its own Form 1099-INT. You add up all the interest from all your accounts and report the total on your tax return. The IRS receives copies of all the 1099-INTs and cross-checks them against your return.

Can I deduct savings account fees from the interest I report?

No. You report the gross interest the bank paid you, not the net amount after fees. Savings account fees are generally not deductible on your personal tax return, though they may reduce your taxable income if you itemize deductions in certain situations.

Is interest from a joint savings account split between owners for tax purposes?

The bank reports the full interest amount on a 1099-INT, but you and the other owner must split the tax liability based on who actually owns the money. If you each own half, you each report half the interest. You may need to file Form 8949 or work with a tax professional to document the split correctly.

What if the interest rate changes during the year?

The tax rate does not change. You pay tax on whatever interest you actually earned at whatever rates applied during the year you earned it. If your account paid 2% in January and 4% in July, you report the total interest earned at both rates combined.
