You must file taxes if your savings account earned interest and you meet the IRS income threshold for your filing status
The IRS requires you to report interest income from savings accounts on your tax return if two things are true: your account earned interest during the year, and your total income exceeds the threshold for your age and filing status. The threshold varies—for 2024, a single person under 65 with only interest income must file if they earned more than $14,600 in total income. A married couple filing jointly needs to exceed $29,200. These numbers change each year.
Your bank will send you a Form 1099-INT in January if your account earned $10 or more in interest during the previous year. This form shows exactly how much interest the IRS knows about. Even if you don't receive a 1099-INT because your interest was under $10, you still owe tax on that interest—you just report it yourself on your return.
The key point: interest income counts toward your total income for filing threshold purposes. If you have a job and a savings account, both earnings add together. If your job income alone puts you over the threshold, you must file regardless of how little interest you earned.
Key Takeaways
- You must file taxes if your total income (including savings interest) exceeds the threshold for your filing status, which ranges from $14,600 to $29,200 depending on age and marital status in 2024.
- Banks report interest of $10 or more on Form 1099-INT, but you owe tax on all interest earned, even amounts under $10.
- Interest income is taxed as ordinary income at your regular tax rate, not at a special rate.
- If you're claimed as a dependent on someone else's return, the filing threshold is lower and based on your own income only.
How the IRS counts savings interest as income
Interest earned in a savings account is treated as ordinary income by the IRS. This means it's taxed at whatever your regular income tax rate is—the same rate applied to wages or salary. You don't get a special lower rate for interest, and you can't exclude it from your income just because it came from savings rather than work.
The amount of interest you owe tax on is the total interest credited to your account during the calendar year, whether you withdrew it or left it in the account. If you earned $47 in interest across all your savings accounts combined, you report $47. If you earned $8.23, you report $8.23.
High-yield savings accounts and money market accounts generate more interest than traditional savings accounts, which means they're more likely to trigger a filing requirement or push you over an income threshold. A high-yield account earning 4% to 5% annually will generate reportable interest much faster than an account earning 0.01%.
Filing thresholds based on your situation
The IRS sets different income thresholds depending on whether you're single, married, a dependent, or over 65. These thresholds increase slightly each year for inflation.
| Filing Status (2024) | Age Under 65 | Age 65 or Older |
|---|---|---|
| Single | $14,600 | $18,350 |
| Married filing jointly | $29,200 | $30,750 (one spouse 65+) |
| Married filing separately | $1,500 | $1,500 |
| Head of household | $21,900 | $25,650 |
| Dependent (claimed on parent's return) | $1,300 earned + $500 unearned | N/A |
If you're claimed as a dependent on your parent's tax return, the threshold is much lower. You must file if you have more than $1,300 in earned income (like wages) or more than $500 in unearned income (like interest). Many teenagers with part-time jobs and savings accounts fall into this category.
Married couples filing separately face the lowest threshold at $1,500 regardless of age. This filing status is rarely used because it usually results in higher taxes, but if you use it, you must file if you have any significant income.
What happens if you don't file when you should
If you owe tax on interest income and don't file, the IRS will eventually notice when your bank reports the interest on Form 1099-INT. The agency may send you a notice demanding payment plus penalties and interest on the unpaid tax. The penalty for not filing is typically 5% of the unpaid tax per month, up to 25% total. Interest accrues daily on top of that.
The IRS doesn't always catch small amounts when ready—they prioritize larger cases—but they do match 1099 forms to tax returns. If you filed a return but didn't report the interest, that's also a mismatch the IRS computer systems flag. You'll receive a notice asking you to explain the discrepancy or pay the difference.
Filing even when you owe a small amount of tax is simpler than waiting for the IRS to contact you. If you file and owe, you can often set up a payment plan. If the IRS files for you or sends a notice, your options are more limited and the penalties are already applied.
How to report savings interest on your tax return
You report interest income on Schedule B (Interest and Ordinary Dividends) if your interest exceeds $1,500, or directly on Form 1040 (the main tax form) if it's $1,500 or less. Most people with only savings account interest use the simpler direct-to-1040 method.
If you receive a Form 1099-INT from your bank, use the amount shown in Box 1 (Interest Income). If you earned interest under $10 and didn't receive a 1099-INT, you still report it—you just write in the amount yourself based on your account statements or year-end summary from your bank.
If you have multiple savings accounts at different banks, add up all the interest from all accounts and report the total. You don't file separate schedules for each account; one line item covers all your interest income.
Strategies to reduce interest income tax
You can't avoid reporting interest income, but you can structure your savings to minimize how much interest you earn in a given year. This is rarely worth the effort for most people, but it's worth understanding the options.
One approach is to keep most money in accounts that earn little or no interest (like a checking account or money market fund) and move funds to a high-yield account only when you're certain you won't cross a filing threshold. This is impractical for most people and defeats the purpose of saving in a high-yield account.
Another option is to hold savings in tax-advantaged accounts like a Roth IRA or 529 college savings plan, where interest and growth are not taxed annually. However, these accounts have contribution limits and withdrawal restrictions, so they're not a substitute for a regular savings account.
For most people, the simplest approach is to file your taxes as required and pay the tax owed on your interest. The tax on $100 in interest is roughly $12 to $24 depending on your tax bracket—not enough to justify complex strategies.
Frequently Asked Questions
Do I have to file taxes if I only earned $8 in savings interest?
Only if your total income (including that $8) exceeds your filing threshold. If you have no other income and earned only $8 in interest, you don't file. If you have a job and your wages plus $8 in interest exceed your threshold, you must file and report the $8.
What if my savings account earned interest but I didn't withdraw it?
You still owe tax on it. The IRS taxes interest when it's credited to your account, not when you withdraw it. If your bank added $50 in interest to your account on December 31, you report that $50 on your taxes for that year, even if you never touched the money.
Will the IRS know about my savings interest if I don't report it?
Yes, if the interest is $10 or more. Your bank sends Form 1099-INT to the IRS, and the IRS computer system matches it to your tax return. If you don't report it, you'll likely receive a notice. Interest under $10 is less likely to be caught, but you're still legally required to report it.
Is interest from a high-yield savings account taxed differently than regular savings?
No. All interest income is taxed at your ordinary income tax rate, regardless of where the account is held or how much interest it earns. A high-yield account earning 4.5% is taxed the same way as a traditional account earning 0.01%.
Do I need to file if I'm a dependent and only have savings interest?
Only if your interest income exceeds $500. If you're claimed as a dependent and earned $600 in interest, you must file. If you earned $400, you don't. This threshold is separate from your parents' filing requirement.
