Interest from a savings account is taxable income
Yes. Any interest your savings account earns is ordinary income to the IRS, taxed at your regular income tax rate. A high-yield savings account earning 4% or 5% generates more interest than a traditional savings account, which means more taxable income in the year you earn it. The bank does not withhold taxes automatically—you owe them when you file your return.
The amount you owe depends on your total income and tax bracket, not on the interest rate itself. Someone in the 22% federal bracket pays roughly 22 cents in federal tax for every dollar of interest earned. State income tax applies too in most states, adding another 3% to 10% depending where you live.
You report this interest on your tax return even if the amount is small. The IRS expects you to include it whether the bank sends you a form or not, though banks typically send a 1099-INT form when interest exceeds $10 in a calendar year.
Key Takeaways
- Interest earned in a savings account counts as ordinary income and is taxed at your full income tax rate, both federal and state.
- Banks send a 1099-INT form when interest exceeds $10 in a year, but you owe tax on all interest regardless of whether you receive the form.
- The tax is due when you file your annual return; no withholding happens automatically, so you may owe a lump sum in April.
- High-yield accounts generate more interest than traditional savings, which means a larger tax bill in the same year.
When the bank sends you a 1099-INT form
Your bank issues a 1099-INT if you earned $10 or more in interest during the calendar year. You receive it by January 31 of the following year. The form shows the total interest paid to you and goes to both you and the IRS, so the IRS already knows about that income before you file.
If you earned less than $10, the bank does not send a form, but you still owe tax on the interest. You report it on your return using the actual amount from your account statements. The IRS does not know about it unless you file, but failing to report it is underreporting income.
If you have accounts at multiple banks, you may receive multiple 1099-INT forms. Add all the interest together when you file—do not report each form separately as if it were different income.
How to report savings account interest on your tax return
Interest income goes on Schedule B (Interest and Ordinary Dividend Income) if you file a full Form 1040. You list each 1099-INT you received and add them up. If you earned less than $1,500 in total interest and dividends combined, you can report the total directly on Form 1040 without filing Schedule B, though many people file it anyway for clarity.
The interest amount flows into your adjusted gross income (AGI), which affects your tax bracket and may reduce other deductions or credits you claim. A large interest payment can push you into a higher bracket or reduce education credits, child tax credits, or other benefits that phase out at higher income levels.
Keep your bank statements for the year. If the 1099-INT amount does not match what you calculated from your statements, contact the bank to request a corrected form before you file. Mismatches are common when accounts opened or closed mid-year.
The difference between federal and state taxes on savings interest
Federal income tax applies to all U.S. residents. Your federal rate depends on your total income and filing status—the same brackets that explore to wages explore to interest. A single filer earning $47,150 to $100,525 in 2024 pays 22% federal tax on additional interest income.
State income tax varies widely. Nine states have no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes interest and dividends but not wages). The remaining 41 states tax interest as ordinary income, with rates ranging from roughly 1% to 13% depending on the state and your income level.
If you live in a high-tax state and earn significant interest, the combined federal and state rate can exceed 40%. A $5,000 interest payment in California (13% state rate) plus 24% federal means roughly $1,850 in total tax owed.
Why high-yield accounts create a larger tax bill
A traditional savings account earning 0.01% on $10,000 generates $1 in annual interest—essentially no tax impact. A high-yield account earning 4.5% on the same $10,000 generates $450 in interest, creating a tax bill of roughly $100 to $180 depending on your bracket and state. The higher the rate, the more interest you earn, and the more you owe in taxes.
This does not mean high-yield accounts are a bad choice. You still keep more money than in a low-rate account even after taxes. But it does mean you should not be surprised by a tax bill in April if you moved money to a high-yield account mid-year. Budget for it or adjust your withholding if you have other income.
Some people move money into high-yield accounts in December and withdraw it in January to spread the interest across two tax years, lowering their bracket impact in each year. This is legal but only saves money if you are close to a bracket boundary.
Tax-advantaged alternatives to regular savings accounts
If you want to earn interest without paying tax on it when ready, a Roth IRA lets you earn interest tax-free as long as the money stays in the account until you reach 59½. You can contribute up to $7,000 per year (or $8,000 if you are 50 or older in 2024), and many Roth IRAs offer high-yield savings options within them.
A Health Savings Account (HSA) also grows tax-free if you have a may have access to high-deductible health plan. You can invest HSA funds in a savings account or other investments, and interest earned is never taxed as long as you use the money for medical expenses.
A 529 college savings plan lets earnings grow tax-free if used for education expenses. Regular savings accounts outside these structures have no tax shelter—all interest is taxable in the year earned.
What happens if you do not report the interest
The IRS matches 1099-INT forms to your tax return. If you received a 1099-INT and did not report the interest, the IRS will notice the mismatch and send you a notice. You will owe the tax plus interest (currently around 8% per year) and may face a penalty of 20% of the unpaid tax if the underreporting was substantial.
If you earned interest below the $10 threshold and did not receive a 1099-INT, the IRS has no automatic way to know unless they audit you. But underreporting is still illegal, and audits do happen. The safest approach is to report all interest, no matter how small.
If you discover you missed interest in a prior year, you can file an amended return (Form 1040-X) for that year. Filing an amendment voluntarily before the IRS contacts you may reduce or eliminate penalties.
Frequently Asked Questions
Do I owe taxes on interest if I only earned $5?
Yes. The $10 threshold only determines whether the bank sends you a 1099-INT form. You owe tax on all interest income, regardless of amount. Report it on your return using your bank statement as proof of the amount.
Can I deduct savings account fees from the interest I earned?
No. You report the gross interest the bank paid you, not the net after fees. Savings account fees are not deductible. However, if you paid investment advisory fees or fees for a brokerage account, those may be deductible under certain conditions—consult a tax professional.
What if I moved money between accounts mid-year and earned interest in both?
Report all interest from all accounts. If you received multiple 1099-INT forms, add them together on Schedule B. The IRS receives copies of all the forms, so they expect the total to match.
Does moving to a high-yield account make sense if I have to pay taxes on the interest?
Usually yes. A 4.5% rate minus 30% in taxes (federal and state combined) still leaves you with roughly 3.15% after-tax return. A traditional savings account at 0.01% leaves you with 0.007% after tax. You come out ahead even after paying taxes, though the difference is smaller than the headline rate suggests.
Can I avoid taxes by keeping my savings under a certain amount?
No. There is no income threshold that exempts savings interest from tax. All interest is taxable income, whether you earned $1 or $10,000. The only way to avoid tax on interest is to keep money in accounts that earn no interest or to use tax-advantaged accounts like Roth IRAs or HSAs.
