Yes, you must report savings account interest as income on your federal tax return
The IRS treats interest earned in a savings account as taxable income. Your bank will send you a Form 1099-INT in January or February if you earned $10 or more in interest during the previous year. You report this amount on your tax return whether or not you receive the form — the $10 threshold is just when the bank is required to send it to you.
The interest gets added to your other income and taxed at your ordinary income tax rate. There is no special rate for savings interest; it is treated the same as wages or salary. If you earned less than $10 in interest, you still report it, but your bank will not send you a 1099-INT.
State income tax rules vary. Some states do not tax interest income at all, while others tax it the same way the federal government does. Check your state's tax authority website to see whether savings interest is taxable in your state.
Key Takeaways
- You must report all savings account interest on your federal tax return, even amounts under $10.
- Your bank sends Form 1099-INT only if you earned $10 or more, but you report smaller amounts too.
- Savings interest is taxed as ordinary income at your regular tax rate, not at a special rate.
- State tax treatment of savings interest varies — some states do not tax it, while others do.
- The interest is added to your total income, which may push you into a higher tax bracket if your income is close to a bracket boundary.
Where to find your interest income on your tax forms
When you file your federal return, you will enter your interest income on Schedule 1 (Form 1040), which is where you report income that does not come from wages. The amount goes on the line for interest income. If you use tax software, it will ask you for this number and place it in the right spot automatically.
If your bank sent you a Form 1099-INT, the interest amount appears in Box 1 of that form. Match this number to what you enter on your return. If you earned interest from multiple accounts or banks, add all the amounts together and report the total.
For state taxes, the process depends on your state. Most states that tax income also have a line for interest income on their state return. A few states exempt interest income entirely, so you would not report it at all. Your state tax form or your tax software will guide you to the right line.
How much interest actually triggers a tax bill
The amount of interest you owe tax on depends on your account balance and the interest rate your bank pays. Current savings account rates range widely — from under 0.01% at some large banks to over 5% at online banks and high-yield savings accounts. The higher the rate, the more interest you earn and the more you owe in taxes.
For example, $10,000 in a savings account earning 0.01% annually generates about $1 in interest, which you still must report but which adds almost nothing to your tax bill. The same $10,000 in an account earning 5% generates $500 in interest, which gets taxed at your marginal rate — potentially $100 to $150 in federal tax depending on your bracket.
If your total income is low enough, you may not owe any federal income tax at all, even with the interest included. The standard deduction for 2024 is $14,600 for single filers and $29,200 for married filing jointly. If your income falls below these amounts, you report the interest but owe no tax.
What happens if you do not report interest income
The IRS receives a copy of every Form 1099-INT that your bank sends to you. If you do not report the interest on your return, the IRS will notice the discrepancy when it matches your return against the forms it received. This mismatch can trigger a notice asking you to explain the difference or pay the tax owed plus penalties and interest.
The penalty for not reporting income is usually 20% of the unpaid tax, plus interest that accrues from the original due date. If the IRS determines the omission was intentional rather than a mistake, the penalty can be higher. The safest approach is to report all interest, even small amounts, when you file.
If you realize you missed interest income on a return you already filed, you can file an amended return using Form 1040-X. The IRS generally allows you to amend returns going back three years. Filing an amended return voluntarily before the IRS contacts you often results in lower or no penalties.
Interest from different account types and what to report
Regular savings accounts, money market accounts, and certificates of deposit (CDs) all generate interest that must be reported. High-yield savings accounts generate more interest but follow the same reporting rules. If you have accounts at multiple banks, you add all the interest together and report the total.
Interest from a joint account is split between the account owners based on each person's ownership stake. If you own the account equally with another person, you each report half the interest. Your bank may send separate 1099-INT forms to each owner, or one form to the primary account holder — check with your bank about how they handle this.
Interest from retirement accounts like traditional IRAs or 401(k)s is not reported on your tax return in the year it is earned. That interest grows tax-deferred inside the account. You only pay tax when you withdraw money from the account in retirement. Savings accounts held outside retirement accounts do not have this tax deferral.
Strategies to reduce the tax impact of savings interest
If you have a large savings balance earning significant interest, you have a few options to manage the tax impact. One approach is to split your money between a regular savings account and a tax-advantaged account like a Roth IRA or a 529 education savings plan. Interest earned inside these accounts is not taxed annually.
Another option is to hold some money in a taxable brokerage account invested in municipal bonds or bond funds. Municipal bond interest is exempt from federal tax and often from state tax too, though this strategy works best if you are in a higher tax bracket. This is not tax avoidance — it is using accounts the tax code already provides.
You can also consider keeping emergency savings in a regular savings account and investing longer-term money in a brokerage account where you have more control over when you realize gains. None of these strategies eliminate the need to report interest income, but they can help you structure your savings in a way that reduces your overall tax burden.
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 Form 1099-INT. You must report all interest income on your tax return, regardless of the amount. If you earned $3 in interest, you report it.
What if my bank did not send me a 1099-INT?
Check your account statements or online banking portal for the interest earned during the year. Add up all deposits labeled as interest and report that total on your return. If you earned $10 or more and did not receive a form, contact your bank — they may have sent it to an old address or it may have been delayed.
Can I deduct savings account fees from the interest I report?
No. You report the gross interest your bank paid you, not the net amount after fees. Savings account fees are not deductible on your personal tax return. You report the full interest amount and pay tax on it, even if fees reduced your net earnings.
Does a high-yield savings account get taxed differently than a regular savings account?
No. Both are taxed the same way — the interest is ordinary income taxed at your regular rate. The only difference is that a high-yield account generates more interest, so you owe more tax on it. The tax treatment itself is identical.
What if I moved money between accounts during the year?
Report the interest earned in each account, regardless of when you moved the money. If you had $5,000 in Account A for six months earning $50, then moved it to Account B for six months earning $50, you report $100 total. Each bank reports only the interest from their own account on their 1099-INT.
