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

The money you put into a savings account is yours—no tax on that. But the interest the bank pays you counts as income to the IRS, and you owe federal income tax on it at your ordinary tax rate. Some states also tax savings interest. The amount you owe depends on how much interest you earned that year and your overall income level.

Your bank will send you a form called a 1099-INT (Interest Income) if you earned $10 or more in interest during the year. You report that number on your tax return. If you earned less than $10, the bank may not send the form, but you still owe tax on the interest—you have to report it yourself.

Key Takeaways

  • Interest earned in a savings account is taxed as ordinary income at your federal tax rate, which ranges from 10% to 37% depending on your income bracket.
  • Your bank sends a 1099-INT form if you earned $10 or more in interest; you report this on your tax return even if the bank does not send the form.
  • Some states tax savings interest, and a few states do not—check your state's rules or ask your bank which states they consider tax-free.
  • High-yield savings accounts earn more interest than traditional savings accounts, which means higher tax bills, but the after-tax return is usually still better.
  • You can reduce taxable interest by holding money in tax-advantaged accounts like IRAs or 529 plans, where interest grows without annual tax.

How the tax gets calculated

The IRS treats savings interest the same way it treats wages or salary—as ordinary income. Your tax rate on that interest depends on your tax bracket, which is determined by your total income for the year. If you earn $50,000 a year and your tax bracket is 22%, then interest counts toward that income and is taxed at 22%.

The math is straightforward: if your savings account earned $500 in interest and you are in the 22% bracket, you owe $110 in federal tax on that interest. If you live in a state that taxes interest—most do, though a handful do not—you owe state tax on top of that. A few states (including Pennsylvania, Tennessee, and Illinois) do not tax interest income at all, which is why some people open accounts in those states even if they live elsewhere.

You do not pay tax on the interest until you file your return, usually the following April. The bank does not withhold it automatically unless you ask them to, so you may need to set aside money to cover the tax bill when it comes due.

When you get a 1099-INT and what it means

If you earned $10 or more in interest during the calendar year, your bank will mail or email you a 1099-INT by January 31 of the following year. This form shows how much interest you earned. You receive a copy, and the IRS receives a copy, so the IRS already knows about your interest income before you file.

The 1099-INT lists interest from all accounts at that bank combined. If you have multiple savings accounts at the same bank, the total appears on one form. If you have accounts at different banks, each bank sends its own 1099-INT.

You report the amount from the 1099-INT on Schedule B (Interest and Ordinary Dividends) if you earned more than $1,500 in interest and dividends combined, or on line 1b of Form 1040 if you earned less. If you earned less than $10 in interest, you still report it on your return, but the bank will not send a form—you have to track it yourself.

State taxes on savings interest

Most states tax interest income the same way the federal government does—as ordinary income at your state tax rate. State rates vary widely, from less than 1% to over 13%, depending on where you live and your income level.

A small number of states do not tax interest income at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax. Pennsylvania and Illinois tax wages but not interest. New Hampshire taxes interest but not wages. If you live in one of these states, you owe only federal tax on your savings interest.

If you live in a state that taxes interest, you report it on your state tax return using the same 1099-INT your bank sent you. Some people who live in high-tax states open savings accounts in low-tax or no-tax states to reduce their state tax bill, though this only works if the bank allows out-of-state accounts and you can prove residency in the lower-tax state.

High-yield savings accounts and the tax impact

A high-yield savings account earns significantly more interest than a traditional savings account—sometimes 4% to 5% annually compared to 0.01% or less at a traditional bank. This means a higher tax bill, but the after-tax return is usually still much better.

If you have $10,000 in a high-yield account earning 4.5%, you earn $450 in interest. At a 22% federal tax rate, you owe $99 in tax, leaving you with $351 in after-tax gain. In a traditional savings account earning 0.01%, you earn $1 in interest and owe roughly $0.22 in tax. The high-yield account is still far ahead even after taxes.

The trade-off is that you have to plan for the tax bill. If you are not used to earning interest, set aside 20% to 25% of what you earn to cover federal and state taxes combined, so you are not caught short when you file your return.

Tax-advantaged accounts that avoid or delay interest tax

If you want to save money without paying annual tax on the interest, you can use a traditional IRA or Roth IRA. Money in these accounts grows without any tax on the interest each year. With a traditional IRA, you pay tax when you withdraw the money in retirement. With a Roth IRA, you pay no tax on withdrawals at all, as long as you follow the rules.

A 529 college savings plan works the same way—interest grows tax-free as long as you use the money for education expenses. If you use it for something else, you owe tax on the earnings plus a 10% penalty.

These accounts have contribution limits and withdrawal rules, so they are not right for all savings goals. But if you are saving for retirement or education, they let you avoid the annual tax hit on interest income.

What happens if you do not report savings interest

The IRS receives a copy of every 1099-INT your bank sends. If you do not report the interest on your tax return, the IRS will notice the mismatch and send you a notice. You will owe the tax you missed, plus interest on that unpaid tax (currently around 8% per year), plus penalties that can range from 20% to 75% of the unpaid tax depending on the reason for the error.

Even if you earned less than $10 and the bank did not send a form, you are still required to report the interest. The IRS does not know about it unless you tell them, but if you are audited and they find unreported interest, the penalties explore.

If you made an honest mistake, filing an amended return (Form 1040-X) as soon as you realize the error reduces penalties significantly. The IRS is more lenient with taxpayers who correct their own mistakes than with those caught during an audit.

Frequently Asked Questions

Do I owe tax on interest if I only earned a few dollars?

Yes. Any interest you earn is taxable income, even if it is $1. You report it on your tax return. The bank only sends a 1099-INT if you earned $10 or more, but you still have to report smaller amounts yourself.

Can I avoid taxes by moving my savings to a different state?

Only if you actually move to a state with no income tax and can prove residency there. Opening an account in another state while living in a high-tax state does not work—you owe tax based on where you live, not where your bank is. Some banks do not allow out-of-state accounts anyway.

What if my savings account earned interest but I did not withdraw it?

You still owe tax on it. The IRS taxes interest when you earn it, not when you withdraw it. If the interest stayed in your account and earned more interest the next year, that second year's interest is also taxable.

Is the interest taxed differently if I am retired?

No. Interest is taxed as ordinary income at your tax bracket, regardless of age or employment status. However, if your total income is low enough, you may not owe any tax at all—the standard deduction covers a certain amount of income tax-free each year.

Do I have to pay estimated taxes on savings interest?

Only if your total tax bill for the year is expected to be $1,000 or more and you do not have enough tax withheld from other sources like wages. Most people with savings interest pay the tax when they file their return in April. Ask a tax professional if you are unsure whether you need to pay estimated taxes.
