Yes, you owe federal income tax on savings account interest, and most states tax it too

The interest your bank pays you counts as taxable income. The IRS treats it the same way it treats wages or investment dividends — you report it on your tax return and pay income tax on the full amount. Your bank will send you a Form 1099-INT each January showing how much interest you earned the previous year, and you use that form to report the income to the IRS.

State income tax works the same way in most states. If your state has an income tax, you report the same interest income on your state return. A handful of states — including Pennsylvania, Illinois, and Mississippi — exempt interest income from state tax, but those are exceptions. Check your state's tax website or ask your tax preparer whether your state taxes interest.

The amount of tax you owe depends on your total income and your tax bracket. Someone in the 12% federal tax bracket pays 12 cents in federal tax on every dollar of interest. Someone in the 22% bracket pays 22 cents. The tax is not a flat rate — it is based on your overall income for the year.

Key Takeaways

  • Your bank reports interest income to the IRS on Form 1099-INT, which you receive by January 31 each year.
  • You must report all savings account interest on your federal tax return, regardless of the amount.
  • Most states tax savings account interest as ordinary income, though a few states exempt it entirely.
  • The tax rate on interest depends on your tax bracket, not on a fixed percentage set by the bank.
  • If you earn less than $600 in interest at one bank, the bank may not send you a 1099-INT, but you still owe tax on that income.

When you receive the Form 1099-INT from your bank

Your bank sends Form 1099-INT to you and to the IRS by January 31 of the year following the one in which you earned the interest. If you had a savings account open during 2024, you will receive the 1099-INT in January 2025. The form shows the total interest paid to you during that calendar year.

You may receive multiple 1099-INTs if you have accounts at different banks or credit unions. Each institution sends its own form. If you have multiple accounts at the same bank, that bank combines the interest from all of them into a single 1099-INT.

The IRS receives a copy of every 1099-INT your bank sends you. This means the IRS already knows how much interest you earned before you file your return. If you do not report the interest on your tax return, the IRS will notice the discrepancy.

Interest income below the reporting threshold

Banks are not required to send a 1099-INT if you earned less than $600 in interest during the year. However, this reporting threshold does not mean you owe no tax on that income. You still must report interest under $600 on your tax return if you file one.

The $600 threshold applies only to the bank's obligation to send the form. The IRS still expects you to report all interest income, no matter how small. If you earned $150 in interest and did not receive a 1099-INT, you still report that $150 on your return.

This matters most for people with very small savings balances or accounts that earned minimal interest. If you are unsure whether you earned more than $600, check your year-end account statement or log into your online banking portal to see the interest posted to your account during the year.

How to report interest income on your tax return

On the federal return, interest income goes on Schedule 1 (Form 1040), line 8b. If you use tax software, the program will ask you to enter the amount from your 1099-INT, and it will place the number in the correct spot automatically. If you file by paper, you write the total interest from all your 1099-INTs on that line.

You do not need to attach the 1099-INT to your return when you file, but you should keep a copy for your records. The IRS has a copy already, so your job is simply to report the same number on your return that appears on the form the bank sent you.

For state taxes, the process is similar. Most state tax forms have a line for interest income. You report the same amount you reported to the IRS. Some states use the federal return as a starting point and then make adjustments, so check your state's instructions to see whether interest is taxed or exempt.

The difference between interest and principal

Only the interest you earn is taxable — not the money you deposited. If you put $10,000 into a savings account and it earns $50 in interest, you owe tax only on the $50. The $10,000 is your principal, which you already paid tax on when you earned it as income or received it from another source.

This distinction matters if you withdraw money from your account. Withdrawing your principal is not a taxable event. You can take out $5,000 of your $10,000 without any tax consequence. The only tax you owe is on the interest the account generated.

High-yield savings accounts and money market accounts

High-yield savings accounts and money market accounts pay more interest than traditional savings accounts, which means you owe more tax on the interest. If a high-yield account pays 4% annual interest on a $50,000 balance, you earn $2,000 in interest that year. That $2,000 is fully taxable at your marginal tax rate.

The higher interest rate does not change the tax treatment — it just means a larger taxable amount. A $2,000 interest payment in the 22% tax bracket costs you $440 in federal tax. This is why some people use high-yield accounts for emergency funds or short-term savings but keep longer-term money in tax-advantaged accounts like IRAs or 401(k)s, where interest and growth are not taxed annually.

The bank still sends a 1099-INT for high-yield accounts the same way it does for regular savings accounts. You report the interest the same way on your tax return.

Frequently Asked Questions

What if I earned interest at multiple banks?

Each bank sends its own 1099-INT. You add up the interest from all the forms and report the total on your tax return. If you earned $300 at Bank A and $250 at Bank B, you report $550 total on Schedule 1, line 8b.

Do I owe tax on interest if I am a dependent?

Yes. Being claimed as a dependent does not exempt you from reporting interest income. You may have a lower tax burden or owe no tax at all depending on your total income, but you still report the interest on your return.

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

No. You report the full interest amount shown on the 1099-INT. Fees charged by the bank are not deductible against interest income on your personal tax return, though they may reduce your net interest earnings.

What happens if the bank sends me a wrong 1099-INT?

Contact the bank and ask them to issue a corrected form (marked as a correction). The bank will send the corrected 1099-INT to you and the IRS. Report the correct amount on your tax return, and keep the corrected form with your records.

Is interest from a joint account taxable to both owners?

The tax treatment depends on how the account is titled and your state's law. In most cases, the person whose Social Security number is on the account receives the 1099-INT and reports all the interest. If you own a joint account, confirm with the bank whose name is listed as the account owner for tax purposes.
