The tax rate on your 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 the interest itself. If you earn $500 in interest and your tax bracket is 22%, you owe roughly $110 in tax on that interest. If your bracket is 12%, you owe roughly $60.
The IRS does not have a separate tax rate for interest income. Instead, your bank reports the interest to the IRS on a Form 1099-INT, and you add that amount to your other income when you file your tax return. Your total income then determines which bracket you fall into, and that bracket applies to everything you earned that year — wages, interest, dividends, and other sources combined.
The federal tax brackets change each year and depend on whether you file as single, married filing jointly, head of household, or another status. For 2024, the brackets range from 10% at the lowest end to 37% at the highest. Most people with modest savings account interest fall into the 12% or 22% brackets.
Key Takeaways
- Savings interest is taxed as ordinary income at your marginal tax bracket rate, not at a flat percentage.
- Your bank reports interest on Form 1099-INT, which you receive by January 31 and must report on your tax return.
- You owe tax on interest even if the bank does not withhold it, so set aside money or make estimated payments if you earn significant interest.
- High-yield savings accounts earn more interest than traditional accounts, which means higher tax bills — but the after-tax return is usually still better.
- Some accounts like Roth IRAs and 529 plans let you earn interest tax-free, depending on how you use the money.
How your tax bracket determines what you owe
Your marginal tax bracket is the rate applied to your last dollar of income. If you are single and earned $45,000 in wages plus $2,000 in savings interest in 2024, your total income is $47,000. That puts you in the 22% bracket, so the $2,000 interest is taxed at 22%, not at a lower rate. You do not pay 22% on all $47,000 — the lower brackets apply to the income below $47,025 — but the interest itself is taxed at your marginal rate.
This matters because earning more interest can push you into a higher bracket. If you were at the top of the 12% bracket and earned enough interest to cross into the 22% bracket, only the income above the threshold is taxed at 22%. The IRS applies brackets progressively, not as a flat rate on everything.
State and local income taxes also apply to savings interest in most states. The rate varies by state — some states do not tax interest income at all, while others tax it at rates up to 13%. You will owe both federal and state tax unless you live in one of the nine states with no income tax (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire, which taxes only interest and dividends).
When the bank withholds tax and when it does not
Banks do not automatically withhold tax from savings interest the way employers withhold from paychecks. The interest is simply added to your account, and you are responsible for reporting it and paying the tax when you file your return. This means you may owe money in April even though no tax was taken out during the year.
The exception is backup withholding, which applies only if you do not provide your bank with a valid tax ID (Social Security number or EIN) or if the IRS has notified the bank that you underreported interest in the past. Backup withholding is 24% and is withheld from your interest. Most people do not encounter this.
If you expect to owe a large amount of tax on interest and other income, you may need to make estimated tax payments four times a year (quarterly) rather than waiting until April. This applies mainly to self-employed people and those with significant investment income. Talk to a tax professional if you earn more than $1,000 in interest in a single year.
Reporting interest on your tax return
Your bank will send you a Form 1099-INT by January 31 of the following year. This form shows the interest you earned in the previous year. You receive a copy and the IRS receives a copy. You must report the amount on your tax return, even if you do not receive the form or if the amount is small.
On a federal return filed with Form 1040, interest income goes on Schedule 1 (Other Income) and then transfers to line 8 of the main form. If you use tax software, it will prompt you to enter the 1099-INT information, and the software will place it in the right spot. If you file by hand or with a tax professional, they will handle the placement.
If you have multiple savings accounts or other sources of interest (bonds, CDs, money market accounts), you add all of it together. The IRS wants your total interest income for the year. If the total is $1,500 or more, you may also need to file Schedule B (Interest and Ordinary Dividends), depending on your filing status and other income.
High-yield savings accounts and the tax impact
High-yield savings accounts currently pay 4% to 5% annual interest, compared to 0.01% or less at traditional banks. This means you earn much more interest — but you also owe much more tax on it. If you have $50,000 in a high-yield account earning 4.5%, you earn $2,250 in interest per year. At a 22% tax bracket, that is roughly $495 in federal tax, plus state tax if applicable.
The after-tax return is still better than a traditional account, but it is lower than the advertised rate. A 4.5% return becomes roughly 3.5% after federal tax at the 22% bracket. This is still far better than 0.01%, so high-yield accounts remain worthwhile — just do not assume the full advertised rate is what you keep.
Some people use high-yield accounts as a temporary holding place for money they plan to move into tax-advantaged accounts like IRAs or 529 plans. Others keep them in lower tax brackets (retirees with modest income, for example) where the tax bite is smaller. The math changes based on your situation.
Tax-free interest in retirement and education accounts
Money in a Roth IRA or Roth 401(k) earns interest and grows tax-free. You do not report the interest on your tax return, and you owe no tax when you withdraw the money in retirement, as long as you follow the rules (age 59½ or older, account open at least five years). This is one of the biggest tax advantages available.
A 529 education savings plan also grows tax-free as long as you use the money for may have access to education expenses (tuition, fees, books, room and board at an accredited school). If you withdraw money for non-may have access to expenses, the earnings portion is taxed and penalized, but the contributions themselves come out tax-free.
Traditional IRAs and 401(k)s defer tax on interest and growth until you withdraw the money in retirement. At that point, withdrawals are taxed as ordinary income. This is different from tax-free growth, but it still lets you avoid paying tax on the interest each year while the money is in the account.
What to do if you earn a lot of interest
If you have a large savings balance or multiple accounts earning significant interest, you may owe enough tax to make a difference in your cash flow. Calculate your expected interest income early in the year, estimate your tax bracket, and set aside money to cover the tax bill. This prevents a surprise in April.
If you earn more than $1,000 in interest and expect to owe more than $1,000 in tax for the year, consider making quarterly estimated payments to the IRS. You can pay online through IRS.gov or by mail. Missing estimated payments can result in penalties and interest charges, even if you pay the full amount when you file.
Another option is to move money into tax-advantaged accounts if you are below the contribution limits. A Roth IRA contribution limit is $7,000 per year (or $8,000 if you are 50 or older). A 529 plan has no annual contribution limit, though gifts over $18,000 per person per year may trigger gift tax reporting. A tax professional can help you figure out the best strategy for your situation.
Frequently Asked Questions
Do I have to pay tax on interest if I earned less than $1,000?
Yes. The IRS taxes all interest income, regardless of the amount. There is no minimum threshold. You must report it on your tax return even if it is $50. However, you may not need to file a tax return at all if your total income is below the filing threshold for your age and status — but if you do file, you report all interest.
What if my bank did not send me a Form 1099-INT?
Contact the bank and request it. Banks are required to send it by January 31. If the bank says the interest was less than $10, they may not be required to send a form, but you still owe tax on it. Report the amount based on your own records or your account statements.
Can I deduct the tax I pay on interest?
No. Interest income is taxable, and you cannot deduct the tax itself. However, if you paid interest on a loan to earn the interest income (rare), you might be able to deduct investment interest expenses, but this has strict limits and is uncommon for savings accounts.
Is interest from a money market account taxed differently?
No. Money market accounts, CDs, and savings accounts are all taxed the same way — as ordinary income at your marginal tax bracket. The bank reports it on a 1099-INT, and you report it on your tax return the same way.
What if I move money between accounts during the year?
You only pay tax on the interest earned, not on the money itself. Moving $10,000 from one account to another does not create a taxable event. Only the interest that account earned is taxable. The bank will report the interest on the 1099-INT for the account where it was earned.
