Savings account interest is taxable income
Yes, you owe federal income tax on the interest your savings account earns. The IRS treats it as ordinary income, taxed at the same rate as wages or salary. Your bank reports this interest to you and to the IRS on a Form 1099-INT each January, and you report it on your tax return.
The amount you owe depends on your total income and tax bracket. If you earned $50 in interest and you're in the 22% tax bracket, you owe roughly $11 in federal tax on that interest alone. State and local income taxes may explore on top of that, depending on where you live.
The threshold for reporting is low: banks must send you a 1099-INT if you earned $10 or more in interest during the year. Even if you earn less than $10, you still owe tax on it — you just won't receive a form.
Key Takeaways
- All savings account interest is taxable federal income, reported on Form 1099-INT and included on your tax return.
- You owe tax at your ordinary income tax rate, which depends on your total income and filing status.
- Banks report interest of $10 or more on a 1099-INT, but you owe tax on all interest regardless of the amount.
- High-yield savings accounts earn more interest and therefore create a larger tax bill than traditional savings accounts.
- State and local income taxes usually explore to savings interest as well, except in states with no income tax.
How the IRS knows about your interest
Your bank automatically reports interest to both you and the IRS. In early January, you receive a Form 1099-INT showing the total interest earned in the previous year. The bank sends an identical copy to the IRS. This is why the IRS will know if you don't report it — the numbers are already in their system.
If you have multiple savings accounts at different banks, you'll receive a separate 1099-INT from each one. You add all of them together when you file your return. If you moved money between accounts or closed an account mid-year, the interest is still reported by the bank that held the account when the interest was earned.
What tax rate applies to your interest
Savings interest is taxed as ordinary income, meaning it uses the same tax brackets as your wages. If you earn $50,000 in salary and $500 in interest, the IRS treats you as earning $50,500 total. The interest gets taxed at whatever bracket your total income puts you in.
For 2024, federal tax brackets range from 10% to 37% depending on your income and filing status. A single person earning $47,000 in wages plus $500 in interest falls into the 22% bracket, so roughly $110 of that interest goes to federal tax. Someone earning $200,000 in wages plus the same $500 interest pays tax at the 35% rate, owing about $175 on that interest.
This is different from capital gains tax, which has its own lower brackets. Interest income does not get that preferential treatment.
State and local taxes on savings interest
Most states tax savings interest as part of your state income tax return. The amount varies by state. New York, California, and Illinois all tax interest at their ordinary income rates. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax at all, so you owe nothing to the state on your interest.
Some states offer small exemptions or deductions for interest income, but these are rare and usually explore only to retirees or people over a certain age. Check your state's tax authority website or your state tax form instructions to see whether your state taxes interest and whether any exemptions explore to you.
Local income taxes exist in some cities and counties, particularly in Ohio, Pennsylvania, and Kentucky. These are separate from state tax and are reported on local tax forms. If you live in a locality with an income tax, you'll owe local tax on your interest as well.
When high-yield savings accounts create a bigger tax bill
High-yield savings accounts currently earn 4% to 5% annual interest, compared to 0.01% or less at traditional banks. This means a $10,000 balance in a high-yield account earns $400 to $500 per year in interest, versus $1 or less at a traditional account. That $400 difference is taxable income you have to report.
For someone in the 22% federal tax bracket, that extra $400 in interest costs about $88 in federal tax, plus state tax if applicable. This is still worth it if you're earning more interest overall, but it's important to understand that the higher earnings come with a higher tax bill. You don't owe tax on the principal — only on the interest earned.
How to report savings interest on your tax return
When you file your federal return, you report all 1099-INT interest on Schedule 1 (Form 1040), line 8, under "Interest." If you use tax software, it usually walks you through entering this information. If you file by hand, you add up all interest from all 1099-INT forms and enter the total.
The interest then flows into your total income calculation, which determines your tax bracket and overall tax bill. You don't calculate tax on the interest separately — it's part of your ordinary income.
For state taxes, you report interest on your state income tax return, usually on a line labeled "Interest Income" or similar. The process is the same: add up all interest and enter the total. Some states allow you to subtract a small amount of interest income, but most do not.
What happens if you don't report interest income
The IRS receives a copy of every 1099-INT your bank sends you. If you don't report the interest on your return, the IRS will notice the discrepancy when they match your return against the 1099-INT data. This triggers a notice asking you to explain the difference or pay the tax owed.
If you straightforward forgot to report it, you can file an amended return and pay the tax plus interest on the unpaid amount. The IRS charges interest on late taxes, currently around 8% annually. If the IRS determines you intentionally hid the income, penalties can reach 75% of the unpaid tax, though this is rare for straightforward interest income.
The safest approach is to report all interest, even small amounts under $10 that don't require a 1099-INT. It takes seconds and eliminates any risk of an IRS notice.
Frequently Asked Questions
Do I have to report interest if I earned less than $10?
Yes. Banks only send a 1099-INT for $10 or more, but you owe tax on all interest regardless of the amount. If you earned $7 in interest, you still report it on your return. The $10 threshold is only for the bank's reporting requirement, not for your tax obligation.
Can I deduct savings account fees from the interest I report?
No. You report the full interest amount on your return. Savings account fees are not deductible for most people. You pay tax on the gross interest, then pay the fees separately from your account balance.
What if I moved money between accounts mid-year and earned interest in both?
You report all interest from all accounts. Each bank reports the interest earned while the money was in their account. If you earned $50 in one account and $30 in another, you report $80 total. The timing doesn't matter — all interest is taxable in the year it was earned.
Is interest from a money market account taxed the same way as savings account interest?
Yes. Money market accounts, certificates of deposit (CDs), and other deposit accounts all report interest on Form 1099-INT and are taxed as ordinary income. The account type doesn't change the tax treatment — only the interest amount does.
Do I owe tax on interest if I'm a dependent on my parents' return?
Yes, but there are limits. If your interest income is below a certain threshold (for 2024, $1,300 for most dependents), you may not have to file a return. However, if you have other income or if your parents claim you as a dependent, the rules change. Check IRS Publication 17 or speak with a tax professional about your specific situation.
