The IRS taxes the interest your savings account earns, not the balance itself

Your bank account balance is not taxed. The money you deposit stays yours without any tax hit. But the interest your bank pays you on that balance is taxable income to the IRS, and you owe federal income tax on it. Some states tax it too. The amount of tax depends on your total income for the year and your tax bracket — the same way wages are taxed.

Your bank reports this interest to you and the IRS on a Form 1099-INT each January. If you earned $10 in interest during the year, that $10 counts as income. If you earned $500, that $500 counts as income. You report it on your tax return, and the IRS expects you to pay tax on it at your ordinary income rate.

Key Takeaways

  • Interest earned in a savings account is taxable income; your bank reports it to the IRS on Form 1099-INT.
  • You pay federal income tax on savings interest at your regular tax bracket rate, and some states add state income tax on top.
  • Banks must send you a 1099-INT if you earned $10 or more in interest during the year, though you owe tax on any amount.
  • High-yield savings accounts earn more interest than traditional accounts, which means higher tax bills on that interest.
  • Tax-advantaged accounts like Roth IRAs and 529 plans let interest grow without annual tax, but have contribution limits and withdrawal rules.

When your bank sends you a 1099-INT form

Your bank issues a Form 1099-INT if you earned $10 or more in interest during the calendar year. The form shows the total interest paid to you and goes to both you and the IRS. You receive it by January 31 of the following year.

If you earned less than $10, your bank does not have to send a 1099-INT, but you still owe tax on that interest if you file a return. The IRS expects you to report it anyway. If you have multiple savings accounts at different banks, each bank sends its own 1099-INT, and you add all the interest together on your tax return.

The 1099-INT also reports other types of interest — from bonds, CDs, money market accounts, and interest-bearing checking accounts. All of it goes on the same form and counts as taxable income.

How much tax you actually owe on savings interest

The tax rate on savings interest is your marginal tax bracket — the same rate that applies to your last dollar of income. If you earn $50,000 a year and file as single, you are in the 22% federal bracket. If your savings account earns $200 in interest, you owe roughly $44 in federal tax on it (22% of $200). If you live in a state with income tax, you owe state tax on top of that.

The exact amount varies by state. Some states do not tax interest income at all. Others tax it at rates between 1% and 13%, depending on your income. A few states tax interest differently than wages — usually lower. You can find your state's rate on your state revenue or taxation department website.

This is why high-yield savings accounts create a larger tax bill than traditional savings accounts. A high-yield account might earn 4% or 5% annually, while a traditional account earns 0.01%. On a $10,000 balance, that difference is $400 to $500 in extra interest — and $88 to $110 in extra federal tax if you are in the 22% bracket, plus state tax.

Accounts where interest is not taxed annually

Certain retirement and education accounts let interest grow without triggering a tax bill each year. A Roth IRA lets you contribute up to $7,000 per year (or $8,000 if you are 50 or older), and all interest and gains grow tax-free forever. You never pay tax on the interest, even when you withdraw it in retirement — as long as you follow the withdrawal rules.

A 529 college savings plan works the same way for education: interest grows tax-free, and you pay no tax when you withdraw it to pay for college tuition, fees, or room and board. Some states also give you a tax deduction for contributions you make to your own state's 529 plan.

These accounts have limits and rules. Roth IRAs have income limits for who can contribute, and you cannot withdraw earnings before age 59½ without a penalty (with narrow exceptions). 529 plans charge a penalty on earnings if you use the money for something other than education. But if you are saving for retirement or education, these accounts can save you hundreds or thousands in taxes over time.

What happens if you do not report savings interest on your taxes

The IRS receives a copy of every 1099-INT your bank sends you. If you do not report the interest on your tax return, the IRS will notice the mismatch between what you reported and what the bank reported. This can trigger an audit notice or a bill for back taxes plus penalties and interest.

The penalty for not reporting income is usually 20% of the unpaid tax, plus interest that compounds daily. If you owed $100 in tax on $500 in interest and did not report it, you could end up owing $120 in penalties alone, plus the $100 in tax, plus interest. The longer you wait to correct it, the more interest accrues.

If you made an honest mistake, you can file an amended return (Form 1040-X) to report the interest and pay what you owe. The IRS is usually willing to waive penalties if you file the amendment before they contact you.

How to reduce the tax on savings interest

The most direct way to reduce tax on savings interest is to use tax-advantaged accounts for as much as you can save. Max out a Roth IRA if you are saving for retirement. Use a 529 plan if you are saving for education. These accounts have annual contribution limits, but they eliminate the annual tax bill on interest.

If you have already maxed out these accounts, a high-yield savings account still makes sense even with the tax bill. Earning 4% interest and paying 22% tax on it leaves you with 3.12% after tax — still far better than the 0.01% you would earn in a traditional account after tax. The tax is a cost of earning more interest, not a reason to earn less.

You can also spread savings across multiple banks or account types to manage your tax bracket. This does not reduce the total tax you owe, but it can help you plan. Some people keep an emergency fund in a regular savings account (earning little interest, creating little tax) and put longer-term savings in a high-yield account or a Roth IRA.

State taxes on savings interest

Nine states do not tax income at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only interest and dividends, not wages). If you live in one of these states, you owe only federal tax on savings interest.

Every other state taxes interest as ordinary income. The rate varies widely. California taxes it at up to 13.3%. New York taxes it at up to 10.9%. Some states tax it at lower rates — Illinois at 4.95%, Pennsylvania at 3.07%. A few states offer exemptions for certain types of interest or for people over a certain age, but these are rare and narrow.

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. This is rare and usually handled automatically if you file returns in both states, but it is worth knowing if you relocated mid-year.

Frequently Asked Questions

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

Your bank does not have to send you a 1099-INT if you earned less than $10, but you still owe tax on it if you file a return. The IRS expects you to report all interest income, regardless of the amount. If you earned $3 in interest, that $3 is taxable.

What if I have savings accounts at multiple banks?

Each bank sends its own 1099-INT. You add all the interest together on your tax return. If you earned $50 at Bank A and $75 at Bank B, you report $125 total on your return. The IRS receives both 1099-INTs and expects the total to match what you report.

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

No. You report the full interest amount on your tax return. You cannot subtract fees or other costs. However, investment-related fees (like fees for managing a brokerage account) may be deductible in limited situations, but savings account maintenance fees are not.

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

Yes. Money market accounts, savings accounts, and CDs all earn interest that is taxed as ordinary income at your marginal tax bracket. Your bank reports it on a 1099-INT the same way. The only difference is the interest rate — money market accounts often pay more than savings accounts.

What if my savings account earns interest but I do not withdraw it?

You owe tax on interest the year it is earned, whether you withdraw it or leave it in the account. The IRS taxes interest on an accrual basis — when the bank credits it to your account, not when you spend it. If your account earned $100 in interest in 2024, you owe tax on that $100 in 2024, even if the money is still sitting in the account.
