Yes, you must report savings account interest as income on your federal tax return

The IRS treats interest earned in a savings account the same way it treats wages or other income. If your bank paid you interest during the year, that money counts as taxable income, and you report it on your tax return. The bank will send you a form called a 1099-INT (Interest Income) by January 31 each year, listing the total interest you earned in that account.

The threshold for reporting is low. If you earned more than $10 in interest during the tax year, the bank must send you a 1099-INT. Even if you earned less than $10, you still owe tax on it—you just won't receive the form. You report the interest on your federal return regardless of the amount.

State and local taxes work the same way. Most states that have an income tax require you to report savings interest. A few states do not tax interest income at all, but you still owe federal tax on it.

Key Takeaways

  • Banks report interest over $10 on a 1099-INT form sent by January 31, and you must include that amount on your federal tax return.
  • You owe federal tax on all savings interest, even amounts under $10 that do not trigger a 1099-INT.
  • Most states tax savings interest the same way the federal government does, though a handful of states do not tax interest income.
  • High-yield savings accounts earn more interest than traditional savings accounts, which means a larger tax bill on that interest.

How the 1099-INT form works and when you receive it

Your bank generates a 1099-INT for each account where you earned interest. If you have multiple savings accounts at different banks, you will receive a separate form from each one. The form shows the account number, the total interest paid to you during the year, and sometimes a breakdown by month.

Banks mail 1099-INT forms by January 31. The IRS receives a copy at the same time. When you file your tax return, you report the interest from all your 1099-INT forms on Schedule 1 (Additional Income), which feeds into your Form 1040. The IRS matches what you report against the copies the banks sent them, so underreporting is caught.

If you do not receive a 1099-INT by early February, contact the bank directly. They may have the wrong address on file, or the interest may have been so small they did not issue one. Either way, you still owe tax on the interest you earned.

The difference between high-yield and traditional savings accounts for tax purposes

A high-yield savings account earns significantly more interest than a traditional savings account—often 4 to 5 percent annually versus 0.01 percent or less. That higher interest rate means a much larger 1099-INT at tax time. A $10,000 deposit in a high-yield account might generate $400 to $500 in interest over a year, while the same amount in a traditional account generates almost nothing.

From the IRS's perspective, both types of interest are taxed identically. The tax rate depends on your overall income and tax bracket, not on where the interest came from. But the practical effect is that high-yield savings accounts create a real tax bill, while traditional savings accounts often do not. This is worth factoring in when deciding where to keep your money.

What happens if you do not report savings interest

The IRS knows about your interest before you file. When the bank sends the 1099-INT to the IRS, they also send it to you. If your return does not include that interest, the IRS will notice the discrepancy. They may send you a notice asking you to pay the tax owed, plus interest on the unpaid amount and potentially a penalty for underreporting.

The penalty for not reporting interest is typically 20 percent of the underpaid tax, though it can be lower if you have a reasonable cause for the mistake. Interest accrues on the unpaid tax from the original due date of your return. Over time, this becomes more expensive than straightforward reporting the interest in the first place.

How to report savings interest on your tax return

When you file your federal return, you report interest income on Schedule 1 (Form 1040), line 8a. You add up all the interest from all your 1099-INT forms and enter the total. If you use tax software, it usually walks you through this step and pulls the information from the form you enter.

If you file by paper, you write the total on the line and attach a copy of your 1099-INT forms to your return. You do not need to list each account separately unless the software or form instructions ask for it. The IRS only cares about the total.

For state taxes, the process is similar. Most state returns have a line for interest income, and you report the same total there. Some states allow you to exclude a small amount of interest income (usually $25 to $100), but you still have to report it and let the state determine whether you owe tax on it.

Strategies that do not reduce your tax bill on savings interest

You cannot avoid reporting savings interest by not opening the account in someone else's name, by moving money between accounts, or by withdrawing the interest before the year ends. The interest is taxable income the moment the bank credits it to your account, regardless of what you do with it afterward. The 1099-INT is based on what the bank paid you, not on what you kept.

Some people ask whether they can claim the interest as a business expense or deduction. You cannot. Interest income is income, and there is no deduction that offsets it. The only way to reduce the tax on savings interest is to earn less interest—by keeping less money in the account or moving it to a lower-yield account—or to offset it with losses elsewhere on your return.

Frequently Asked Questions

Do I have to report interest if I earned less than $10?

Yes. The bank only sends you a 1099-INT if you earned more than $10, but you owe tax on all interest, even $1. You report it on your return the same way, and the IRS expects to see it.

What if I have interest from a savings account at a credit union instead of a bank?

Credit unions follow the same rules as banks. They send a 1099-INT for interest over $10 and report it to the IRS. You report it on your tax return the same way.

Can I deduct the taxes I owe on savings interest from my return?

No. You report the interest as income, and then you pay tax on it at your regular rate. There is no deduction for the tax itself. The only exception is if you paid estimated taxes during the year, which you can credit against your final bill.

Does a joint savings account change how I report interest?

If the account is jointly owned, the bank may split the interest between both owners on separate 1099-INT forms, or they may report it all to one person. Check your forms and report what you actually received. If the bank reported it all to you but you own it jointly, you may need to adjust your return or coordinate with the other owner.

What if my bank made a mistake on the 1099-INT?

Contact the bank and ask them to issue a corrected form (called a 1099-INT with a corrected indicator). Once you receive it, file an amended return with the correct amount. Keep documentation of the error in case the IRS questions the discrepancy.
