Savings account interest is taxable income to the IRS

Yes, you owe federal income tax on the interest your savings account earns. The IRS treats it as ordinary income, taxed at your regular tax rate — not at a lower capital gains rate. If you earned $10 in interest, that $10 is added to your other income for the year and taxed accordingly.

The bank or financial institution holding your account will report this interest to you and to the IRS on a Form 1099-INT (Interest Income). You then report that same amount on your tax return. The IRS cross-checks the two documents, so if you don't report it, they will notice the mismatch.

State and local income taxes also apply to savings interest in most states that have income tax. A few states — including Florida, Texas, and Wyoming — have no state income tax at all, so residents there owe only federal tax on interest. Other states tax it at their regular income tax rate.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your federal tax rate, regardless of how small the amount.
  • Your bank sends you a Form 1099-INT if you earned $10 or more in interest during the year, and you must report that amount on your tax return.
  • The IRS receives a copy of your 1099-INT, so unreported interest will trigger a mismatch notice.
  • State income tax applies to savings interest in most states, but a handful of states have no income tax at all.
  • You report savings interest on Schedule 1 (Form 1040) or on your tax software's interest income section.

When you get a Form 1099-INT and what it means

Your bank issues a Form 1099-INT if you earned $10 or more in interest during the calendar year. You should receive it by January 31 of the following year. The form shows the total interest paid to you in box 1, and sometimes breaks out other types of interest in other boxes — but for a regular savings account, box 1 is what matters.

If you have multiple savings accounts at different banks, you will receive a separate 1099-INT from each one. If you have multiple accounts at the same bank, they may combine them into a single form. The bank keeps a copy and sends one to you and one to the IRS.

If you earned less than $10 in interest, the bank does not have to send you a 1099-INT, but you still owe tax on that interest if you file a return. You can find the exact amount in your account statements or by logging into your online banking portal and checking the year-to-date interest earned.

How to report savings interest on your tax return

On a federal return, you report interest income on Schedule 1 (Form 1040), line 8a. If you use tax software, it will ask you about interest income and automatically put it in the right place. You enter the total from all your 1099-INT forms combined.

If you file a paper return, write the total on line 8a of Schedule 1, then transfer that amount to line 1b of Form 1040. The software does this transfer for you automatically.

For state taxes, the process varies. Most states that have income tax ask you to report interest on their version of a 1040 or on a separate interest income schedule. Your state tax software or a tax preparer can walk you through the exact lines. If you file both federal and state returns, you report the same interest amount to both — it is not divided between them.

What happens if you don't report savings interest

The IRS receives a copy of every 1099-INT your bank sends you. If your tax return does not include that interest, the IRS computer system flags it as a mismatch. You will receive a notice in the mail asking you to explain the difference or pay the tax owed plus interest and penalties.

The penalty for not reporting interest income is typically 20% of the unpaid tax, plus interest that accrues from the original due date. If the IRS determines the omission was intentional, the penalty can be higher. Even if it was an honest mistake, you still owe the tax and interest retroactively.

The easiest approach is to report it when you file. If you discover you missed it in a prior year, you can file an amended return (Form 1040-X) for that year. The IRS generally does not pursue small amounts aggressively, but it is not worth the risk or the hassle of a notice.

How much tax you actually owe on savings interest

The tax you owe depends on your total income and tax bracket. If you earn $10 in interest and you are in the 22% federal tax bracket, you owe roughly $2.20 in federal tax on that interest (plus state tax if your state has income tax). If you are in the 12% bracket, you owe roughly $1.20. The interest is added to your other income, and the tax is calculated on the combined total.

This is why high-yield savings accounts matter: they pay more interest, which means more tax, but also more money in your pocket after tax. A regular savings account earning 0.01% interest on $10,000 generates $1 per year in interest and roughly 12 to 22 cents in federal tax. A high-yield account earning 4.5% on the same $10,000 generates $450 in interest and roughly $54 to $99 in federal tax — but you keep $351 to $396 instead of 78 cents.

You can estimate your tax liability by multiplying the interest earned by your marginal tax rate (the rate on your last dollar of income). If you are unsure of your bracket, tax software will calculate it for you when you enter all your income.

Savings interest and the standard deduction

If your total income — including savings interest — is below the standard deduction for your filing status, you may not owe federal income tax at all. For 2024, the standard deduction is $14,600 for a single filer and $29,200 for married filing jointly. If your wages plus interest plus all other income falls below that threshold, you have no federal tax liability.

However, you may still be required to file a return for other reasons — for example, if you are self-employed or if you have a dependent. And even if you do not owe tax, filing a return can get you a refund of taxes withheld from paychecks. Check the IRS filing requirements on their website or use their interactive tool to determine whether you must file.

State tax rules vary widely. Some states have a lower threshold than the federal standard deduction, and some have none at all. A few states tax interest income differently than federal law does. If you live in a state with income tax, check your state revenue department's website for the specific rules.

Frequently Asked Questions

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

The bank does not have to send you a 1099-INT, but you still owe tax on the interest if you file a return. You can find the exact amount in your account statements. If your total income is below the standard deduction, you may not owe tax, but you should still report it accurately on your return.

What if I have savings accounts at multiple banks?

Each bank sends you a separate 1099-INT for the interest it paid. You add up all the interest from all your forms and report the total on your tax return. The IRS receives copies from each bank, so they will see the total as well.

Is savings account interest taxed differently than other types of interest?

No. Savings account interest is taxed as ordinary income at your regular tax rate. Interest from bonds, CDs, and money market accounts is also taxed the same way. Capital gains (from selling stocks or mutual funds) are taxed at lower rates, but savings interest does not may have access to.

Can I deduct any expenses related to my savings account?

No. Interest income is reported as-is; you cannot deduct account fees, minimum balance penalties, or other costs against it. Those expenses are not deductible on your personal tax return.

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

Contact the bank and ask them to issue a corrected form (Form 1099-INT with a "Corrected" checkbox marked). They will send the corrected version to you and to the IRS. Once you receive it, report the corrected amount on your tax return. If you already filed, you may need to file an amended return.
