Interest on savings accounts counts as ordinary income on your federal tax return
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 have to report it, and you owe federal income tax on it. Most states also tax savings account interest as part of your state income tax.
Your bank will send you a Form 1099-INT in January if you earned $10 or more in interest during the previous year. You report this amount on your federal tax return, and it gets added to your other income to determine your tax bracket and how much you owe. Even if you don't receive a 1099-INT because your interest was under $10, you still have to report the interest if you file a return.
The tax rate you pay depends on your total income for the year and your filing status — not on the interest amount itself. Someone in the 22% tax bracket pays more tax on $100 of interest than someone in the 12% bracket, even though it's the same $100.
Key Takeaways
- Your bank reports interest earnings to the IRS on Form 1099-INT if you earned $10 or more, and you must report this on your tax return.
- Interest is taxed as ordinary income at your marginal tax rate, which depends on your total income and filing status, not on the interest amount alone.
- You owe federal income tax on all savings account interest, and most states tax it as well.
- High-yield savings accounts pay more interest but are also fully taxable, so the after-tax return may be lower than it appears.
How the IRS gets the information and when you report it
Banks are required to report interest paid to account holders and to the IRS. If your account earned $10 or more in interest during the calendar year, your bank mails you a Form 1099-INT by January 31. This form shows the total interest paid and goes to the IRS at the same time it goes to you.
You report this interest on your tax return for that year. On the federal form (Form 1040), interest income goes on Schedule 1, line 8a. If you file electronically, your tax software will ask you to enter the amount from your 1099-INT. If you file by paper, you attach the 1099-INT to your return or keep it for your records.
The IRS cross-checks the 1099-INT your bank sends with the amount you report on your return. If you don't report interest that appears on a 1099-INT, the IRS will likely catch it and send you a notice. Reporting the correct amount avoids penalties and interest charges on unpaid tax.
What tax rate applies to your interest income
Interest is taxed at your marginal tax rate — the rate that applies to your highest dollar of income. If you're single and earn $50,000 in wages, and you earn $500 in interest, that $500 is taxed at the same rate as your last $500 of wages, not at a lower rate.
For 2024, federal tax brackets range from 10% to 37%, depending on your total income and filing status. A single filer with $50,000 in income falls into the 22% bracket, so each additional dollar of interest is taxed at 22%. A single filer with $500,000 in income is in the 35% bracket, so the same $500 in interest costs them $175 instead of $110.
State income tax rates vary widely. Some states don't tax income at all (Florida, Texas, Wyoming, and others). States that do tax income typically apply rates between 3% and 13%, added on top of federal tax. So your total tax on interest could range from just the federal amount to federal plus state combined.
Why high-yield savings accounts don't change the tax picture
High-yield savings accounts pay significantly more interest than traditional savings accounts — sometimes 4% to 5% annually compared to 0.01% at a regular bank. But every dollar of that higher interest is still fully taxable at your marginal rate.
If you earn $1,000 in interest at a high-yield account and you're in the 24% federal bracket plus a 5% state bracket, you owe $290 in combined tax on that $1,000. Your after-tax return is $710, not $1,000. This doesn't make high-yield accounts a bad choice — they still beat traditional savings accounts after tax — but it's important to understand that the advertised rate is not the rate you keep.
Money market accounts and certificates of deposit (CDs) work the same way: all interest is taxable at your marginal rate, regardless of the account type or how high the rate is.
How interest affects your overall tax situation
Interest income can push you into a higher tax bracket. If you're close to a bracket boundary, additional interest might increase the tax rate on all your income above that threshold. For example, if you're single and earn $47,000 in wages, you're in the 12% bracket. If you earn $3,500 in interest, your total income becomes $50,500, which moves you into the 22% bracket. The extra $3,500 in interest is taxed at 22%, not 12%.
Interest can also affect whether you may have access to for certain tax credits or deductions. Some credits phase out as your income rises, so additional interest income might reduce or eliminate a credit you would otherwise receive. This is less common for savings account interest alone, but it matters if you have other investment income as well.
If you're retired and receiving Social Security, interest income is included in the calculation that determines whether your benefits are taxable. This is one reason some retirees move money to tax-advantaged accounts or bonds that generate less taxable income.
Strategies to reduce taxable interest income
You can't avoid tax on interest you've already earned, but you can structure your savings to minimize future interest income. One option is to use a Roth IRA or Roth 401(k), where interest and other earnings grow tax-free and withdrawals in retirement are not taxed. Contributions to these accounts are limited ($7,000 per year for IRAs in 2024, higher for 401(k)s), but the tax savings can be substantial over time.
A traditional IRA or 401(k) defers tax on interest until you withdraw the money in retirement, which may be at a lower tax rate. A 529 education savings plan allows interest to grow tax-free if the money is used for education expenses.
For money you need to keep accessible, a high-yield savings account still makes sense even though the interest is taxable — you're earning more after tax than you would in a regular savings account. The tax is a cost of earning the interest, not a reason to avoid earning it.
What to do if you don't receive a 1099-INT
If your interest was less than $10 for the year, your bank is not required to send you a 1099-INT. You still have to report the interest on your tax return if you file one. Check your year-end account statement or your online banking portal to find the exact amount of interest paid.
If you earned $10 or more and don't receive a 1099-INT by early February, contact your bank. The form may have been mailed to an old address, or there may be an error in the bank's records. Ask the bank to send you a corrected form or a statement showing the interest paid. Keep records of all interest earned, even small amounts, in case the IRS asks.
If you received a 1099-INT with an incorrect amount, ask your bank for a corrected form (called a 1099-INT with "CORRECTED" marked on it). Report the corrected amount on your tax return and keep the corrected form with your records.
Frequently Asked Questions
Do I have to report interest if I earned less than $10?
Yes. The $10 threshold only determines whether your bank sends you a 1099-INT. You must report all interest income on your tax return, even if it's $1. Check your account statement for the exact amount and include it on your return.
What if I have interest in multiple savings accounts?
Add up the interest from all your accounts and report the total on your tax return. If the combined total is $10 or more, you'll receive a 1099-INT from each bank that paid you interest. Report each one separately on your return, or combine them into a single line item — your tax software will handle this automatically.
Can I deduct the taxes I pay on interest income?
No. Interest income is added to your other income, and you pay tax on the total. You cannot deduct the tax itself. However, if you paid estimated taxes or had taxes withheld from other income, those payments reduce your overall tax bill.
Is interest taxable if I'm a minor with a savings account?
Yes. A minor's interest income is taxable and must be reported on a tax return. If the minor has no other income and interest is their only income, they may not have to file a return if the interest is below the filing threshold (around $1,250 for 2024), but it depends on their age and filing status. Parents should check IRS rules or consult a tax professional.
Does a joint savings account change how interest is taxed?
No. Interest on a joint account is still taxable income. The bank reports it to the IRS, and both account holders are responsible for reporting it. You and the other owner should decide how to split the interest for tax purposes — typically each person reports their proportional share on their own return.
