Savings account interest counts as income the IRS taxes

Interest your bank pays you on a savings account is taxable income. The IRS treats it the same way it treats wages or freelance earnings — you report it on your tax return and pay federal income tax on it. Some states also tax savings interest, depending on where you live.

Your bank will send you a Form 1099-INT each January if you earned $10 or more in interest during the previous year. This form lists exactly how much interest you made. You use that number when you file your taxes. Even if your bank doesn't send you a 1099-INT because your interest was under $10, you still owe tax on whatever you earned — you just have to report it yourself.

The amount of tax you pay depends on your total income for the year and your tax bracket. Someone in the 22% bracket pays more tax on the same $100 of interest than someone in the 12% bracket. This is why the tax bill varies from person to person, even when the interest earned is identical.

Key Takeaways

  • The IRS requires you to report all savings account interest as income on your federal tax return, regardless of the amount.
  • Your bank sends a Form 1099-INT if you earned $10 or more in interest; amounts under $10 still require you to report the interest yourself.
  • The tax rate on your interest depends on your overall income and tax bracket, not on the interest amount alone.
  • Some states tax savings interest in addition to federal tax, while others do not — check your state's rules.
  • High-yield savings accounts earn more interest, which means a larger tax bill, so factor that into your planning.

How the 1099-INT form works and what it tells you

In early January, your bank mails or emails you a Form 1099-INT if your interest income hit $10 or more during the previous calendar year. The form shows the total interest paid to you in Box 1. This is the number you report to the IRS when you file your return.

You receive one 1099-INT per bank account that earned interest, so if you have multiple savings accounts at different banks, you may get several forms. You need to add up all the interest from all your forms and report the total on your tax return. The IRS also receives a copy of each 1099-INT you get, so they know what your bank paid you.

If you earned less than $10 in interest, your bank is not required to send a 1099-INT. However, you still owe tax on that interest. You report it yourself on your return under "other income" or on Schedule 1, depending on which form you use.

What happens if you don't report savings interest

When the IRS receives a copy of your 1099-INT from your bank, they cross-reference it against your tax return. If you don't report the interest income, the IRS will notice the discrepancy. They may send you a notice asking you to explain the difference or file an amended return.

Failing to report interest income can result in penalties and interest charges on the unpaid tax. The penalty is usually 20% of the underpaid tax, plus interest that compounds daily. If the IRS determines the omission was intentional rather than a mistake, the penalty can be steeper.

The easiest approach is to report the interest when you file. The tax bill is usually small — even $1,000 in interest at a 22% rate costs only $220 — and reporting it avoids the risk of penalties and the hassle of dealing with the IRS later.

State taxes on savings interest vary by location

Federal tax is not the only tax you may owe on savings interest. Most states also tax interest income, but the rules differ. Some states tax all interest the same way the federal government does. Others exempt certain types of interest or offer deductions for savers over a certain age.

A few states — including Wyoming, South Dakota, Tennessee, and Texas — do not tax interest income at all. If you live in one of these states, you owe federal tax on your savings interest but no state tax. If you live elsewhere, your state tax return will ask you to report the same interest income you reported to the IRS.

Your state will not send you a separate form for state tax purposes; you use the same 1099-INT your bank sent you. Check your state's tax website or ask a tax preparer about the rules in your state, especially if you moved during the year or have income from multiple states.

How high-yield savings accounts affect your tax bill

High-yield savings accounts pay significantly more interest than traditional savings accounts — sometimes 4% to 5% annually compared to 0.01% at a regular bank. This higher rate means more interest income, which means a larger tax bill.

If you have $10,000 in a high-yield account earning 4.5% annually, you earn $450 in interest. At a 22% federal tax rate, that costs you $99 in federal tax alone. The same $10,000 in a traditional savings account earning 0.01% earns only $1 in interest and costs you about $0.22 in tax. The difference is real and worth factoring into your savings strategy.

This does not mean high-yield accounts are a bad choice — the interest you earn still exceeds the tax you pay. But it does mean you should not be surprised by a tax bill when you file. If you earn significant interest, you may want to set aside money throughout the year to cover the tax, or adjust your withholding if you have a job.

Reporting interest on your tax return

When you file your federal return, you report savings interest on Form 1040, Schedule 1, under "Interest." Add up all the interest from all your 1099-INT forms and enter the total. If you use tax software, it will usually walk you through this step and ask you to enter the amount from Box 1 of your 1099-INT.

If you earned less than $10 in interest and did not receive a 1099-INT, you still report it on Schedule 1 under "Other income." Write "Interest income" next to the amount so the IRS knows what it is.

For state taxes, follow your state's instructions. Most states have a similar line on their return where you report interest income. Some states allow you to file electronically; others require a paper return for certain situations. Check your state's tax agency website for the specific form and instructions.

Strategies to reduce taxes on savings interest

You cannot avoid reporting savings interest, but you can reduce the amount of interest you earn — and therefore the tax you owe — by keeping less money in a savings account. This is not usually a good strategy, because the interest you earn almost always exceeds the tax you pay on it. Earning $100 in interest and paying $22 in tax still leaves you $78 ahead.

A more practical approach is to use tax-advantaged accounts for long-term savings. A Roth IRA or traditional IRA allows you to save money and earn interest without paying tax on the interest each year. Contributions to a traditional IRA may also reduce your taxable income in the year you make them. These accounts have annual contribution limits and withdrawal rules, so they work best for retirement savings rather than emergency funds.

Another option is to keep your emergency fund in a high-yield savings account (which is taxable but earns good interest) and put longer-term savings into a retirement account. This way you earn interest on both, but only pay tax on the savings account interest.

Frequently Asked Questions

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

Yes. The IRS requires you to report all interest income, even amounts under $10. Your bank is not required to send you a 1099-INT for interest under $10, but you still owe tax on it. Report it on Schedule 1 of your Form 1040 under "Other income."

What if I have multiple savings accounts at different banks?

You will receive a separate 1099-INT from each bank if the interest was $10 or more. Add up all the interest from all your 1099-INT forms and report the total on your tax return. If you have accounts under $10 at some banks, add those amounts to your total as well.

Can I deduct savings account fees from the interest I report?

No. You report the full interest amount your bank paid you, not the net amount after fees. However, some taxpayers can deduct investment-related expenses on Schedule A, though the rules are strict and most people do not benefit from this deduction.

Does a joint savings account change how interest is taxed?

The interest is still taxable income. If the account is jointly owned, you and the other owner may each report a portion of the interest, or one person may report all of it — this depends on how the account is titled and your agreement with the other owner. Check with your bank about how they report joint account interest on the 1099-INT.

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

Contact your bank and ask them to issue a corrected form. They will send you a corrected 1099-INT and also send a corrected copy to the IRS. Report the corrected amount on your tax return. If you already filed, you may need to file an amended return once you receive the corrected form.
