Interest from a high yield savings account is taxed as ordinary income
The money your high yield savings account earns counts as taxable income. The bank or financial institution reports what you earned to the IRS on a Form 1099-INT, and you report it on your tax return. You pay tax at your regular income tax rate — the same rate you pay on wages or salary — not at a special lower rate.
This applies to every dollar of interest, no matter how small. If your account earned $50 in interest over the year, that $50 is taxable income. If it earned $5,000, all $5,000 is taxable. There is no threshold below which interest becomes tax-free.
The tax is owed in the year the interest is credited to your account, even if you do not withdraw the money. If your account earned interest in December 2024, you owe tax on it when you file your 2024 return in 2025, regardless of when you actually spend or move that money.
Key Takeaways
- High yield savings interest is taxed as ordinary income at your regular tax rate, reported on Form 1099-INT by your bank.
- You owe tax on all interest earned in the calendar year, even if you leave the money in the account and do not withdraw it.
- Banks report interest to the IRS only if you earned $10 or more in a calendar year, but you must report all interest regardless of the amount.
- The higher your account balance and the higher the APY, the more interest you earn and the more tax you owe on that interest.
- Tax-advantaged accounts like IRAs and 401(k)s can hold high yield savings without triggering annual tax on the interest.
When the bank reports your interest to the IRS
Your bank sends Form 1099-INT to the IRS if you earned $10 or more in interest during the calendar year. You receive a copy of this form by January 31 of the following year. The form shows your name, Social Security number, and the total interest earned.
If you earned less than $10, the bank does not file the form with the IRS, but you still owe tax on that interest. You must report it yourself on your tax return. The IRS cross-checks 1099-INT forms against tax returns, so underreporting or omitting interest is a common audit trigger.
If you have multiple high yield savings accounts at different banks, each bank reports separately. You add up all the interest from all accounts when you file your return.
How much tax you actually owe depends on your tax bracket
The tax rate on interest is your marginal tax rate — the rate you pay on your last dollar of income. If you are in the 22% federal tax bracket, you owe 22% of your interest as federal income tax. If you are in the 12% bracket, you owe 12%. The higher your total income, the higher your bracket and the more tax you owe on the same amount of interest.
State income tax also applies in most states. If your state has income tax, you owe state tax on the interest at your state rate in addition to federal tax. Some states tax interest at a lower rate than wages, but most do not. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — do not have state income tax at all.
Example: If you earn $2,000 in interest and you are in the 24% federal bracket with 5% state income tax, you owe $480 in federal tax plus $100 in state tax, for a total of $580. Your account keeps $1,420.
Tax-advantaged accounts that avoid annual interest tax
If you hold a high yield savings account inside a traditional IRA or Roth IRA, you do not owe tax on the interest each year. The interest compounds tax-free until you withdraw money from the account. With a traditional IRA, you owe tax when you withdraw. With a Roth IRA, withdrawals in retirement are tax-free if you follow the rules.
A 401(k) or other employer retirement plan can also hold high yield savings or money market funds. Interest grows tax-deferred, and you owe tax only when you withdraw in retirement (or never, in the case of a Roth 401(k) if you follow the rules).
A 529 college savings plan allows interest to grow tax-free if the money is used for may have access to education expenses. If you withdraw for non-education purposes, you owe tax on the earnings portion plus a 10% penalty.
These accounts have contribution limits and withdrawal rules. A traditional or Roth IRA allows you to contribute up to $7,000 per year (or $8,000 if you are 50 or older). A 401(k) limit is much higher — $23,500 per year in 2024. Talk to a tax professional or financial advisor about whether these accounts make sense for your situation.
How to report interest on your tax return
If you file Form 1040 (the standard federal income tax form), interest income goes on Schedule 1, line 8. If you use tax software, it will prompt you to enter interest income and automatically place it in the right spot. If you file by hand, you add up all your 1099-INT forms and enter the total.
You do not need to attach the 1099-INT forms to your return, but keep them for your records. The IRS has a copy, and if your return does not match what the bank reported, you may receive a notice asking you to explain the difference.
If you earned less than $10 and received no 1099-INT, you still report the interest. Write it in on Schedule 1 or enter it in your tax software. This is especially important if you have multiple small accounts or if you opened an account late in the year.
Strategies to reduce taxable interest income
You cannot avoid tax on interest, but you can reduce how much interest you earn and therefore how much tax you owe. Moving money to a regular savings account with a lower APY reduces interest earned. Withdrawing money from the account stops it from earning interest going forward. Neither of these is a tax strategy — they are just ways to earn less money.
The most effective way to reduce tax on savings is to use a tax-advantaged account like an IRA or 401(k) if you are saving for retirement. If you are saving for a near-term goal — a car, a home down payment, an emergency fund — a high yield savings account is still the right place for the money, even though you owe tax on the interest. The interest rate is high enough that the after-tax return usually beats other options like money market funds or CDs.
If you are in a very high tax bracket and earn substantial interest, a tax professional can discuss whether your situation warrants strategies like bunching income into certain years or using losses to offset gains. These are uncommon and require specific circumstances.
What happens if you do not report interest income
If you do not report interest on your tax return and the bank reported it on a 1099-INT, the IRS will notice. The IRS matches 1099 forms against tax returns automatically. If your return does not include the interest, you will receive a notice of underreported income, usually within a year or two of filing.
You will owe the tax you should have paid, plus interest on that tax (currently around 8% per year), plus a penalty. The penalty for negligence is usually 20% of the underpaid tax. If the IRS determines the underreporting was intentional fraud, the penalty can be as high as 75%.
Reporting interest is straightforward and takes minutes. The cost of not reporting — in taxes, interest, and penalties — far exceeds any benefit of trying to hide it.
Frequently Asked Questions
Do I owe tax on interest if I earned less than $10?
Yes. The bank only files a 1099-INT if you earned $10 or more, but you owe tax on all interest regardless of the amount. You must report it on your tax return even if you received no form from the bank.
Can I deduct the interest I earned as a business expense?
No. Interest income is not deductible. You report it as income and pay tax on it. You cannot offset it with unrelated business expenses or deductions.
What if I moved money between accounts during the year?
Only the interest earned counts as taxable income. Moving the principal from one account to another is not taxable. If you earned $500 in interest across multiple accounts, you owe tax on $500 regardless of how many times you moved the money itself.
Does a high yield savings account in a child's name get taxed differently?
Interest is taxed at the child's tax rate, not the parent's. A child with no other income may owe no tax on interest below a certain threshold (the standard deduction), but the interest is still reported. A tax professional can advise on the rules for dependent children.
Is interest from a high yield savings account taxed differently than interest from a regular savings account?
No. Both are taxed as ordinary income at your regular tax rate. The only difference is the amount of interest earned — a high yield account earns more, so you owe tax on a larger amount.
