Yes, the IRS taxes interest earned in savings accounts as ordinary income

Any interest your savings account earns is taxable income. The IRS treats it the same way it treats wages or salary — you owe federal income tax on it at your regular tax rate. Your bank reports this interest to the IRS on a Form 1099-INT, and you report it on your tax return.

The amount of tax you owe depends on two things: how much interest you earned and your overall income for the year. A person in the 22% tax bracket who earns $500 in savings interest will owe roughly $110 in federal tax on that interest. Someone in the 12% bracket earning the same $500 will owe roughly $60. State income tax, where it exists, is added on top.

The bank does not withhold this tax automatically — you pay it when you file your return. If you expect to owe more than a certain amount (currently $1,000 for most people), you may need to make quarterly estimated tax payments to avoid penalties.

Key Takeaways

  • Interest earned in any savings account is taxable as ordinary income at your federal tax rate, plus state income tax if your state has one.
  • Your bank reports interest over $10 to the IRS on Form 1099-INT, which you receive by January 31 and must report on your tax return.
  • High-yield savings accounts earn more interest than traditional savings accounts, which means more tax owed, but the after-tax return is usually still higher.
  • You can reduce taxable interest by holding money in tax-advantaged accounts like IRAs, 401(k)s, or Roth accounts, where interest grows tax-free or tax-deferred.

When your bank sends the IRS a report of your interest

If you earn $10 or more in interest during a calendar year, your bank must send you a Form 1099-INT by January 31 of the following year. This form lists the interest you earned at that bank. If you have accounts at multiple banks, you will receive a separate 1099-INT from each one.

The bank sends a copy to the IRS at the same time. The IRS uses this to check whether the interest you reported on your tax return matches what the bank reported. If you do not report interest that appears on a 1099-INT, the IRS will likely notice and send you a notice of underreported income.

You must report all interest income on your tax return, even if you did not receive a 1099-INT (for example, if you earned less than $10 at one bank). The IRS expects to see it.

How high-yield savings accounts change the tax picture

A high-yield savings account earns significantly more interest than a traditional savings account — often 4% to 5% annually, compared to 0.01% or less at many large banks. This means more money in your pocket, but also more taxable income.

If you keep $10,000 in a high-yield account earning 4.5%, you will earn $450 in interest over a year. At a 22% federal tax rate, you owe roughly $99 in federal tax on that interest. Your after-tax return is $351. Compare that to a traditional savings account earning 0.01% on the same $10,000: you earn $1 in interest and owe roughly $0.22 in tax, leaving you $0.78. The high-yield account is still far ahead even after taxes.

The tax on high-yield interest is real, but it does not erase the advantage. If you are comparing accounts, calculate the after-tax return by multiplying the interest rate by (1 minus your tax rate), then apply that to your balance.

Tax-advantaged accounts that shield savings from tax

If you want to avoid paying tax on savings interest, you need to hold the money in a tax-advantaged account. The most common ones are:

  • Traditional IRA or 401(k): Interest and investment gains grow without being taxed each year. You pay tax only when you withdraw the money in retirement.
  • Roth IRA or Roth 401(k): Interest and gains grow tax-free. You pay no tax on withdrawals in retirement, as long as you follow the rules.
  • Health Savings Account (HSA): If you have a high-deductible health plan, an HSA lets you save money tax-free for medical expenses. Interest is not taxed.
  • 529 College Savings Plan: Money saved for education grows tax-free as long as it is used for may have access to education expenses.

These accounts have contribution limits and rules about when you can withdraw money without penalty. A traditional IRA, for example, allows you to contribute up to $7,000 per year (or $8,000 if you are 50 or older), and you generally cannot withdraw before age 59½ without paying a 10% penalty plus income tax.

If you have money you will not need for several years, moving it into one of these accounts can save you hundreds or thousands in taxes over time.

What happens if you do not report savings interest on your tax return

The IRS receives a copy of every 1099-INT your bank sends you. If you do not report the interest on your return, the IRS will match the 1099-INT against your return and flag the discrepancy. You will receive a notice asking you to explain the difference or pay the tax owed.

If you owe tax and do not pay it, the IRS charges interest on the unpaid amount (currently around 8% per year) plus a penalty. The penalty for not reporting income is typically 20% of the underpaid tax. On $450 in unreported interest at a 22% tax rate, you would owe roughly $99 in tax, plus $20 in penalties, plus interest that grows each month you do not pay.

Reporting the interest when you file your return is simpler and cheaper than dealing with the IRS later. If you made a mistake in a prior year, you can file an amended return (Form 1040-X) to correct it.

State income tax on savings interest

Most states that have an income tax also tax savings interest at your state tax rate. A few states do not tax interest income — currently, Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax. New Hampshire and Tennessee tax only interest and dividend income, not wages.

If you live in a state with income tax, you will owe state tax on your savings interest in addition to federal tax. A person in California earning $500 in savings interest, for example, owes federal tax plus California state tax, which can total 35% or more depending on their income level.

If you move to a different state during the year, you may owe tax to both states on the interest you earned while living in each one. Your state tax return will ask where you lived and for how long.

Frequently Asked Questions

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

Yes. Your bank only sends a 1099-INT if you earned $10 or more, but you must report all interest income on your tax return, even if it is $5 or $8. The IRS expects to see it, and leaving it off can trigger a notice.

Can I deduct savings account fees from my taxable interest?

No. You report the full interest amount on your tax return. Fees you pay to the bank are not deductible against the interest income. However, some investment-related fees may be deductible under other rules — consult a tax professional if you have significant fees.

What if I earned interest at a bank that went out of business?

If the bank failed and was insured by the FDIC, you will still receive a 1099-INT for the interest earned before the failure. Report it on your tax return. If the bank was not insured and you lost money, you may be able to claim a casualty loss, but this requires specific documentation and IRS approval.

Does moving money between my own savings accounts create a tax event?

No. Transferring money from one savings account to another is not taxable. Only the interest the money earns is taxed. Moving $5,000 from Account A to Account B creates no tax liability.

If I close my savings account mid-year, do I still owe tax on the interest?

Yes. You owe tax on all interest earned during the year, regardless of when you close the account. The bank will report the interest on your 1099-INT, and you report it on your tax return for that year.
