The tax rate on savings interest depends on your total income and filing status
Savings account interest is taxed as ordinary income, which means it is taxed at the same rate as your wages or salary. The amount you owe depends on your tax bracket for the year, not on a flat rate applied to interest alone. If you earned $50,000 in wages and $500 in interest, the $500 is added to your $50,000 and taxed according to where that $50,500 falls in the tax brackets for your filing status.
The federal tax brackets change each year. For 2024, a single filer in the 22% bracket pays 22% on each additional dollar of income, including interest. A married couple filing jointly might be in the 12% bracket, so their interest would be taxed at 12%. The brackets shift upward slightly each year for inflation, so your rate may change year to year even if your income does not.
Some states also tax savings interest. New York, California, and most other states treat it the same way — as ordinary income taxed at your state rate. A handful of states (including Pennsylvania, Illinois, and Mississippi) do not tax interest income at all. Your state tax rate, if you have one, stacks on top of the federal rate.
Key Takeaways
- Savings interest is taxed at your ordinary income tax rate, which depends on your total income and filing status, not on a fixed percentage.
- Federal tax brackets for 2024 range from 10% to 37%, and your interest is taxed at whichever bracket your total income falls into.
- Most states tax savings interest as ordinary income, but a few states do not tax interest at all — check your state's rules.
- You report savings interest on your tax return using Form 1099-INT, which your bank sends you by January 31 each year.
- Interest under $10 may not require a 1099-INT, but you still owe tax on it if your total income crosses the threshold for filing.
How federal tax brackets work with your interest income
The U.S. tax system uses progressive brackets, meaning different portions of your income are taxed at different rates. You do not jump into a higher bracket entirely — only the income that falls within that bracket is taxed at that rate. If you are single and your income reaches $47,150 in 2024, you are in the 22% bracket, but only the dollars above $47,150 are taxed at 22%.
When you add savings interest to your income, it fills in from the top of your current bracket upward. If you earned $46,500 in wages and your interest is $1,000, that $1,000 pushes you to $47,500 total. The first $650 of interest stays in the 12% bracket, and the remaining $350 moves into the 22% bracket. Your total tax on that interest is not a flat rate — it is split across two brackets.
This matters because a small amount of interest can push you into a higher bracket and increase your overall tax bill. It also means that if you are close to a bracket threshold, earning interest might cost you more in taxes than the interest itself is worth. Knowing your expected income for the year helps you understand whether your savings interest will stay in your current bracket or climb into the next one.
State taxes on savings interest vary widely
Most states tax savings interest as ordinary income at their state rate. If your state income tax rate is 5%, you owe 5% federal plus your state rate on top of it. Some states have progressive brackets like the federal system, so your state rate also depends on your total income.
A small number of states do not tax interest income at all. Pennsylvania, Illinois, Mississippi, and a few others exempt interest from state tax, though they may tax other forms of income like wages or capital gains. If you live in one of these states, you owe only federal tax on your savings interest. If you moved during the year or work in a different state than you live in, your state tax situation may be more complex — you may owe tax to both states or neither, depending on where you earned the income and where you filed.
Some states also offer tax breaks for interest earned in certain accounts. A few states exempt interest in education savings accounts (529 plans) from state tax. Check your state's tax agency website or a tax professional to confirm whether your state taxes savings interest and at what rate.
When you receive a 1099-INT and how to report it
Your bank sends you a Form 1099-INT by January 31 each year if you earned $10 or more in interest during that year. The form shows the total interest paid to you and any federal tax already withheld (which is rare for savings accounts). You receive one copy and the IRS receives another, so the IRS knows about your interest income whether or not you report it.
You report the interest on your tax return using Schedule B (Form 1040) if you have more than $1,500 in interest or dividends combined. If you have less than that, you can report it directly on Form 1040 line 2b. The interest amount goes into your total income for the year, and your tax is calculated based on your full income, including that interest.
If you earned interest but did not receive a 1099-INT because it was under $10, you still owe tax on it. The IRS does not require the bank to send a form, but you are responsible for reporting it. Keep your own records of all interest earned, even small amounts, so you can report it accurately on your return.
How high-yield savings accounts affect your tax bill
High-yield savings accounts pay significantly more interest than traditional savings accounts — sometimes 4% to 5% annually, compared to 0.01% at many large banks. This higher interest means a larger amount to report and a larger tax bill. A $10,000 deposit earning 4.5% generates $450 in interest per year, which is taxed at your ordinary income rate. That same $10,000 in a traditional account earning 0.01% generates only $1 in interest.
The tax on high-yield interest can be substantial if you have a large balance or are in a higher tax bracket. Someone in the 24% federal bracket plus a 5% state bracket pays 29% tax on their interest. On $450 in interest, that is $130.50 in taxes. The account still makes sense financially if the after-tax return beats other options, but the tax impact is real and worth calculating before you move money.
Some people use high-yield savings accounts as a short-term holding place for money they plan to spend or invest soon. Others use them for emergency funds. The tax treatment is the same regardless — all interest is taxed as ordinary income in the year it is earned, even if you do not withdraw the money.
Tax-advantaged alternatives to regular savings accounts
If you want to save money and reduce your tax bill, several account types offer tax advantages. A traditional IRA or 401(k) lets you contribute pre-tax dollars, and interest earned inside the account is not taxed until you withdraw it in retirement. A Roth IRA lets you contribute after-tax dollars, but interest and withdrawals are tax-free in retirement. A Health Savings Account (HSA) offers triple tax benefits: contributions are deductible, interest is not taxed, and withdrawals for medical expenses are tax-free.
These accounts have contribution limits and withdrawal rules, so they are not a replacement for a regular savings account. But if you have money you do not need to touch for several years, moving it into one of these accounts can save you significant tax on the interest. A $10,000 deposit earning 4.5% in a Roth IRA generates $450 in interest that is never taxed, compared to $450 that is fully taxable in a regular savings account.
529 education savings plans also offer tax benefits for interest earned, though the rules depend on your state. Some states exempt 529 interest from state tax. Federal tax on 529 interest is deferred until the money is withdrawn for education expenses, and if used for may have access to education costs, the earnings are tax-free.
What to do if you owe more tax than you expected
If your interest income pushed you into a higher tax bracket or you did not expect to owe tax, you have options. You can adjust your withholding on your W-4 form at work so that more tax is taken from each paycheck, which reduces your tax bill at filing time. You can also make quarterly estimated tax payments if you have significant interest income and no employer withholding.
If you owe tax but cannot pay it all at once, the IRS allows payment plans. You can request a short-term plan (up to 180 days) with no setup fee, or a long-term installment agreement with a small setup fee. Interest and penalties accrue on unpaid tax, so paying as soon as you can is cheaper than waiting.
For future years, you can move money into tax-advantaged accounts or reduce the amount you keep in taxable savings accounts. Some people split their savings between a high-yield account (for money they might need soon) and a Roth IRA or other tax-sheltered account (for longer-term savings). This strategy lets you earn higher interest on some money while avoiding tax on the rest.
Frequently Asked Questions
Do I owe federal tax on interest if I earned less than $10?
Yes. The $10 threshold only determines whether your bank sends you a 1099-INT form. You owe tax on all interest income, regardless of the amount. Keep your own records and report it on your tax return.
What if my interest income is so small it does not push me into a higher tax bracket?
You still owe tax on it at your current bracket rate. If you are in the 12% bracket and earn $50 in interest, you owe $6 in federal tax (plus any state tax). The interest is taxed even if it does not change your bracket.
Can I deduct the taxes I pay on savings interest?
No. Interest income is taxed as ordinary income, and you cannot deduct the tax you pay on it. You report the full interest amount and pay tax on it; there is no offsetting deduction.
Do I owe tax on interest if I did not withdraw the money?
Yes. You owe tax on interest in the year it is earned and credited to your account, even if you leave it there and do not withdraw it. The tax is based on when the interest is earned, not when you spend the money.
What happens if I do not report interest income on my tax return?
The IRS receives a copy of your 1099-INT and will notice if you do not report it. Unreported income can trigger an audit, penalties, and interest charges on the unpaid tax. It is simpler and cheaper to report it correctly the first time.
