Yes, savings account interest counts as income on your tax return
Interest your bank pays you on a savings account is taxable income. The IRS treats it the same way it treats wages or salary — it goes into your gross income for the year. Your bank will send you a Form 1099-INT in January or February showing how much interest you earned, and you report that amount on your federal tax return.
The amount matters less than you might think for most people. If you earned less than $10 in interest during the year, your bank may not send you a 1099-INT at all, though you still owe tax on it. If you earned more, the bank is required to report it, and the IRS receives a copy too.
State income tax works the same way — interest is taxable income in every state that has an income tax. A few states exempt interest from state tax but not federal, so you may owe federal tax on the interest even if your state does not tax it.
Key Takeaways
- Savings account interest is reported to the IRS on Form 1099-INT and must be included in your gross income on your tax return.
- Banks report interest of $10 or more; amounts under $10 may not generate a 1099-INT but are still taxable.
- The tax you owe on interest depends on your total income and tax bracket, not on the interest amount alone.
- Interest is taxable at both federal and state levels in most states, even if the amount is small.
How the IRS knows about your interest
Your bank is required by law to report interest payments to the IRS using Form 1099-INT. The bank sends you a copy and files another copy with the IRS under your Social Security number. This happens automatically — you do not have to do anything to trigger it.
The IRS matches the 1099-INT it receives from your bank against your tax return. If you do not report the interest on your return, the IRS will notice the mismatch and may send you a notice asking why. Even small amounts of unreported interest can trigger an audit letter.
If your bank pays you less than $10 in interest during the year, the bank may not send a 1099-INT. However, you are still required to report that interest on your tax return. The IRS does not receive a copy, but that does not mean you can skip it — the tax law requires you to report all income, regardless of whether a form is issued.
What happens to your tax bill when you add interest income
The tax you owe on interest depends on your total income and your tax bracket, not on the interest amount by itself. If you earn $30,000 a year and your savings account pays you $50 in interest, that $50 is added to your $30,000, making your taxable income $30,050. You pay tax on that $50 at whatever rate applies to your bracket.
For most people, the tax on savings interest is small because the interest itself is small. A savings account earning 4% on a $5,000 balance generates $200 a year in interest — roughly $40 to $50 in federal tax, depending on your bracket. High-yield savings accounts pay more, so the tax is higher, but the principle is the same.
Interest can push you into a higher tax bracket if you are close to the edge, but this is rare. More commonly, interest simply increases your taxable income by a small amount, and you pay a small amount of additional tax.
Reporting interest on your tax return
When you file your federal return, you report interest income on Schedule 1 (Form 1040), line 8. If you use tax software, it will ask you for the amount from your 1099-INT and fill in the form for you. If you file by hand, you write the amount in the box labeled "Interest" and add it to your other income.
You need the 1099-INT to file accurately, but you do not need to attach it to your return. Keep it with your tax records for at least three years in case the IRS asks questions later.
For state taxes, the process is similar. Most state returns have a line for interest income, and you report the same amount you reported to the IRS. A few states have different rules — for example, some states exempt interest from state tax but not federal — so check your state's instructions if you live in a state with income tax.
Interest from different types of savings accounts
All interest is taxable, regardless of the account type. A regular savings account, a money market account, a certificate of deposit (CD), and a high-yield savings account all generate taxable interest. The bank reports it all on Form 1099-INT.
CDs have a special rule: if the CD matures in less than one year and you withdraw early, you may owe an early withdrawal penalty. That penalty is deductible on your tax return, which can offset some of the tax on the interest. The bank reports both the interest and the penalty on the 1099-INT.
Interest from an IRA or 401(k) is not reported on a 1099-INT because those accounts are tax-deferred. You do not pay tax on the interest while it sits in the account. You pay tax when you withdraw the money in retirement.
What to do if you did not receive a 1099-INT
If your bank paid you interest but did not send a 1099-INT, contact the bank and ask for one. Banks are required to send them by January 31 if interest was $10 or more. If the bank says it did not send one because the interest was under $10, ask for a statement showing the interest paid — you will need that to report the income on your return.
If you cannot get a 1099-INT from the bank, use your bank statement to calculate the interest. Most statements show interest paid each month, so you can add them up. Report that total on your tax return even without the form.
If the IRS sends you a notice saying your 1099-INT does not match your return, respond promptly. Usually this means the bank reported interest you did not report, or reported a different amount. Gather your bank statements and the 1099-INT and explain the difference. If the bank made an error, ask the bank to file a corrected 1099-INT (Form 1099-INT with an "X" in the correction box).
Interest and other income thresholds
Interest does not trigger any special tax thresholds by itself, but it can push your total income over limits that affect other parts of your taxes. For example, if you are over a certain income level, you may have to pay the Net Investment Income Tax, which is an additional 3.8% tax on investment income including interest. The threshold is $200,000 for single filers and $250,000 for married filing jointly.
Interest can also affect whether you have to file a return at all. If your only income is interest and it is below the standard deduction for your age and filing status, you may not have to file. However, if you had taxes withheld from other income, you should file to get a refund.
If you receive Social Security, interest income can affect how much of your benefits are taxable. The IRS uses a formula that includes interest as part of your "combined income," which determines whether you owe tax on your benefits.
Frequently Asked Questions
Do I have to report interest if I only earned a few dollars?
Yes. The tax law requires you to report all income, even amounts under $10. Your bank may not send a 1099-INT for amounts under $10, but you still owe tax on it. Use your bank statement to find the amount and report it on your return.
Can I deduct the tax I pay on savings interest?
No. Interest income is added to your gross income, and you pay tax on it at your regular rate. You cannot deduct the tax itself. However, if you paid an early withdrawal penalty on a CD, that penalty is deductible and reduces your taxable interest income.
What if I moved money between banks during the year?
Each bank reports the interest it paid you on a separate 1099-INT. You report all of them on your tax return by adding up the amounts from each form. The IRS receives copies from each bank, so make sure your return includes all of them.
Does interest from a joint savings account get split between owners?
The bank reports all interest to the Social Security number listed as the account owner or primary account holder. If the account is truly joint, you and the other owner should agree on how to split the interest for tax purposes and report it accordingly. The IRS may ask for clarification if the 1099-INT does not match what you reported.
Is interest taxable if I reinvest it instead of withdrawing it?
Yes. Interest is taxable in the year it is earned, whether you withdraw it, leave it in the account, or reinvest it. The IRS taxes the interest when the bank credits it to your account, not when you spend or move the money.
