Yes, you must report all savings account interest on your federal tax return, no matter how small the amount
The IRS requires you to report every dollar of interest your bank pays you. There is no minimum threshold — even $1 of interest must be reported. Your bank will send you a Form 1099-INT in January if you earned $10 or more in interest during the previous year, but you are required to report interest below $10 as well, even if you never receive a form.
Interest counts as ordinary income, which means it is taxed at your regular income tax rate. The amount you owe depends on your total income and tax bracket, not on the interest amount itself. If you fail to report interest income, the IRS can assess penalties and interest on the unpaid tax, and in some cases pursue more serious enforcement action.
Key Takeaways
- You must report all savings account interest on your federal return, including amounts under $10 that do not trigger a 1099-INT form.
- Your bank sends Form 1099-INT only when interest reaches $10 or more, but the absence of a form does not mean you skip reporting.
- Interest is taxed as ordinary income at your regular tax rate, so the tax you owe depends on your total income for the year.
- If you have multiple savings accounts, add up all the interest from all accounts and report the total on one line of your return.
How the 1099-INT form works and what it tells you
Banks issue Form 1099-INT to report interest paid during the calendar year. You receive this form by January 31 if your interest totaled $10 or more. The form shows the account number, the interest amount, and your tax identification number (usually your Social Security number). You receive one copy and the bank sends a copy to the IRS.
The form itself is not your tax bill — it is a record of income you received. You use the amount shown on the 1099-INT as the starting point for reporting on your return. If you earned interest from multiple banks or accounts, you will receive a separate 1099-INT from each one. You add them all together when you report.
If your interest was less than $10, you will not receive a 1099-INT at all. You still must report that interest on your return. Check your account statements or contact your bank directly if you are unsure of the exact amount.
Where interest income goes on your tax return
Interest income appears on Schedule B (Interest and Ordinary Dividends) if you have more than $1,500 in total interest and dividend income for the year. If your interest is $1,500 or less, you can report it directly on Form 1040 (the main return form) without filing Schedule B, though many people file Schedule B anyway for clarity.
The line item is typically labeled "Interest" or "Interest income." You enter the total amount from all your 1099-INT forms and any unreported interest below $10. The total then flows to your overall income calculation, which determines your tax bracket and final tax bill.
If you file electronically, your tax software will walk you through entering this information. If you file by paper, the instructions that come with Form 1040 show you exactly where to write the number.
What happens if the 1099-INT amount is wrong
If the amount on your 1099-INT does not match your account statements, contact your bank first. Banks sometimes make errors — a deposit might be coded as interest when it should not be, or interest might be reported twice. Ask the bank to issue a corrected form (called an amended 1099-INT) if there is a mistake.
Once the bank issues a corrected form, you report the corrected amount on your return. Keep the original and corrected forms together with your tax records. If the IRS later questions the discrepancy, you can show both forms and explain that the bank corrected the error.
If you report the correct amount on your return but the IRS has the wrong amount from the original 1099-INT, the IRS may send you a notice. Respond with a copy of the corrected 1099-INT and your return showing the correct figure. This usually resolves the issue without penalty.
Interest from different account types and special situations
Regular savings accounts, money market accounts, and certificates of deposit (CDs) all generate interest that must be reported. Interest from high-yield savings accounts is reported the same way — the higher rate does not change the reporting requirement.
If you have a joint account with another person, the bank may split the interest between two 1099-INT forms, or it may report all interest to one person. Check with your bank about how they handle joint accounts. You and the other account holder should coordinate to make sure the interest is reported correctly and not duplicated on both returns.
Interest earned in a traditional IRA or 401(k) is not reported on your personal return — those accounts are tax-deferred, meaning you do not pay tax on the interest until you withdraw the money. Interest in a Roth IRA is also not reported. Only interest in non-retirement accounts counts as taxable income in the current year.
Penalties and consequences of not reporting interest
If you do not report interest income and the IRS discovers it through the 1099-INT they received from your bank, they will assess tax on the unreported amount plus a penalty. The penalty for negligence is typically 20 percent of the unpaid tax. You will also owe interest on the unpaid tax, calculated from the original due date of the return.
The IRS matches 1099-INT forms to tax returns automatically. If your return shows no interest income but your bank reported interest to the IRS, a mismatch notice is likely. You can respond by filing an amended return, but you will still owe the tax and penalties for the years involved.
Intentional failure to report income can result in fraud penalties of up to 75 percent of the unpaid tax, plus criminal prosecution in extreme cases. For most people, the issue is straightforward forgetting to report small amounts — filing an amended return as soon as you realize the mistake minimizes penalties.
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 form. You are required to report all interest income, regardless of amount. Check your account statements and include any interest below $10 on your return.
What if I have interest from multiple banks?
Add up all the interest from all your accounts and report the total as one line item on your return. You will receive a separate 1099-INT from each bank, but you combine them into a single number when you report.
Is interest from a savings account taxed differently than other income?
No. Interest is ordinary income, taxed at your regular tax rate based on your total income for the year. It is not taxed at a special rate like long-term capital gains or may have access to dividends.
What if my bank sent me a 1099-INT but I think the amount is wrong?
Contact your bank and ask them to verify the amount against your account statements. If there is an error, request an amended 1099-INT. Report the corrected amount on your return and keep both forms with your records.
Do I report interest from a joint savings account on my personal return?
That depends on how your bank reports it. Some banks split the interest between two 1099-INT forms, others report all of it to one person. Check with your bank and coordinate with the other account holder to avoid reporting the same interest twice.
