Yes, you owe federal income tax on savings account interest
The interest your bank pays you on a savings account is taxable income. The IRS treats it the same way it treats wages or salary — you must report it on your federal tax return every year. Your bank will send you a form called a 1099-INT in January showing how much interest you earned the previous year, and you use that number when you file.
The amount of tax you actually owe depends on your total income and your tax bracket. If you earned $50 in interest and you're in the 22% tax bracket, you don't automatically owe $11 — you owe 22% of your total taxable income after deductions. The interest gets added to everything else you earned that year, and then your tax is calculated on the combined total.
Some states also tax savings interest, though the rules vary. A few states don't tax interest income at all, while others tax it like the federal government does. Check your state's tax website or ask a tax preparer what applies where you live.
Key Takeaways
- Banks report savings interest to the IRS on form 1099-INT, and you must include that amount on your federal tax return.
- The tax you owe is based on your overall income and tax bracket, not a flat percentage of the interest itself.
- You only receive a 1099-INT if you earned $10 or more in interest during the year, but you still owe tax on smaller amounts.
- Some states tax savings interest and some do not — your state's rules are separate from federal tax.
- High-yield savings accounts earn more interest than traditional savings accounts, which means a larger tax bill on that interest.
When you get a 1099-INT form and what it means
In late January or early February, your bank mails or emails you a 1099-INT if you earned $10 or more in interest during the previous calendar year. This form shows the total interest paid to you. You use the number on Box 1 of the form when you fill out your tax return.
The 1099-INT goes to the IRS at the same time it goes to you. That means the IRS already knows how much interest you earned — if you don't report it on your return, the IRS will notice the mismatch. Reporting the interest is not optional, even if the amount is small.
If you earned less than $10 in interest, your bank may not send you a 1099-INT, but you still owe tax on that interest. You have to add it to your return yourself. Keep your bank statements so you can calculate the total if you need to.
How much tax you actually owe on savings interest
Your tax rate on savings interest is the same as your ordinary income tax rate — it's not a special lower rate. If you're in the 12% federal tax bracket, you pay 12% on the interest. If you're in the 24% bracket, you pay 24%. The interest is added to your other income, and your total tax is calculated on everything combined.
Here's a concrete example: suppose you earned $500 in savings interest and your other income puts you in the 22% tax bracket. You don't owe $110 on just the interest. Instead, the $500 gets added to your total taxable income, and your overall tax bill increases by roughly $110 (the exact amount depends on deductions and credits). The interest itself is taxed at your marginal rate.
If your income is very low, you might not owe any federal tax at all, even with the interest included. The standard deduction — the amount you can earn before owing federal tax — is $13,850 for a single person in 2024 and $27,700 for married couples filing jointly. If your total income is below that, you owe no federal tax.
State taxes on savings interest
Nine states have no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only interest and dividends, but many savings accounts don't generate enough to owe). If you live in one of these states, you don't owe state tax on savings interest.
Most other states tax interest income the same way the federal government does — as ordinary income at your state tax rate. A few states offer small deductions or exemptions for interest earned on savings, but the rules are specific to each state. Your state tax return will have a line for interest income, and you report the same 1099-INT amount there.
If you live in one state but earn interest from a bank in another state, you owe tax to the state where you live, not where the bank is located. Your state of residence is what matters for state income tax.
High-yield savings accounts and tax consequences
A high-yield savings account earns significantly more interest than a traditional savings account — sometimes 4% to 5% annually instead of 0.01%. That higher interest is a real advantage for your savings, but it also means a larger amount to report on your taxes.
If you have $10,000 in a high-yield account earning 4.5%, you'll earn roughly $450 in a year. That's $450 you have to report as income. In a traditional savings account earning 0.01%, you'd earn about $1 and might not even get a 1099-INT. The tax difference is real, but the high-yield account still leaves you ahead because the interest earned is much larger than the tax on it.
Some people move money between accounts to manage tax timing, but the IRS taxes interest based on the year it was earned, not when you move the money. If interest posts to your account in December, you owe tax on it in that tax year, regardless of whether you withdraw it later.
What happens if you don't report savings interest
The IRS receives a copy of every 1099-INT your bank sends you. If you don't report the interest on your tax return, the IRS will see the discrepancy when they match your return against the forms they received. This can trigger an audit or a notice asking you to explain the difference.
Failing to report interest income is considered tax evasion if it's intentional, though most cases of unreported interest are honest mistakes. The penalty for underpaying taxes is usually a percentage of the unpaid amount plus interest on that amount, calculated from the original due date. The longer the mistake goes unnoticed, the more interest and penalties accumulate.
If you realize you missed reporting interest from a previous year, you can file an amended return using Form 1040-X. It's better to correct it yourself than to wait for the IRS to contact you, because the IRS is more likely to waive penalties if you file the amendment before they initiate contact.
Frequently Asked Questions
Do I have to report savings interest if I only earned a few dollars?
Yes. Even if you earned $5 in interest and didn't receive a 1099-INT, you still owe tax on it. The IRS requires you to report all interest income. However, if your total income is below the standard deduction, you may not owe any federal tax even after including the interest.
Can I deduct the taxes I pay on savings interest?
No. Interest income is added to your taxable income, but you cannot deduct the tax you pay on it. You can deduct investment expenses in some cases, but not the tax itself. The interest is taxed as ordinary income with no special deduction available.
What if I have savings accounts at multiple banks?
Each bank that paid you $10 or more in interest will send you a separate 1099-INT. You add up all the interest from all the forms and report the total on your tax return. The IRS receives copies of all the forms, so they know your total interest income from all sources.
Is interest from a money market account taxed the same way?
Yes. Money market accounts, certificates of deposit (CDs), and other savings products that earn interest are all taxed the same way as a regular savings account. The bank reports the interest on a 1099-INT, and you report it as ordinary income on your federal and state returns.
Do I owe taxes on interest if I'm under 18?
Yes. Age doesn't matter for tax purposes — if you earned interest income, you owe tax on it. A minor with a savings account must report the interest on a tax return. Parents or guardians may be able to claim the child as a dependent, which affects the child's standard deduction, but the interest itself is still taxable.
