Your bank reports the interest you earn, and you owe income tax on it

The money your savings account earns through interest is taxable income. Your bank tracks how much interest you made during the year and reports it to the IRS on a form called a 1099-INT. You then include that interest amount when you file your income tax return, just as you would report wages from a job.

The tax you owe depends on your total income for the year and your tax bracket — the higher your income, the higher the percentage of tax you pay. If you earned $50 in interest and you are in the 22% tax bracket, you would owe roughly $11 in federal income tax on that interest alone. State income tax may explore as well, depending on where you live.

This happens automatically once you earn the interest. You do not have to do anything to trigger the tax — it is straightforward part of how the tax system works. The bank does not withhold the tax from your account; you pay it when you file your return.

Key Takeaways

  • Interest earned in a savings account counts as taxable income and must be reported on your tax return.
  • Your bank sends you a 1099-INT form by January 31 each year showing the total interest you earned.
  • The amount of tax you owe on the interest depends on your overall income and your tax bracket.
  • You report the interest when you file your income tax return, not when you earn it.
  • Some savings accounts earn so little interest that you may not receive a 1099-INT if the amount falls below the reporting threshold.

When your bank sends you the 1099-INT form

By January 31 of each year, your bank mails or emails you a 1099-INT form that shows all the interest you earned in that account during the previous calendar year. This form has your name, your account number, and the total interest amount. The bank also sends a copy to the IRS, so the IRS already knows how much interest you made.

If you earned less than $10 in interest during the year, your bank may not send you a 1099-INT — the IRS does not require banks to report amounts below that threshold. However, you still owe tax on that interest if you are required to file a return. You would need to track it yourself or ask your bank for a statement showing the interest.

Keep the 1099-INT with your tax documents. When you file your return, you will enter the interest amount from this form into the appropriate line on your tax return or give it to a tax preparer.

How the interest amount affects your tax bill

The interest you earn is added to your other income for the year — wages, self-employment income, rental income, or anything else taxable. Your total income then determines which tax bracket you fall into and how much tax you owe overall.

If you earned $40,000 in wages and $500 in savings account interest, your taxable income is $40,500. That extra $500 pushes you slightly higher in the tax brackets, so you pay a bit more tax than you would have on the $40,000 alone. The exact amount depends on your filing status and other factors, but the principle is straightforward: more income means more tax.

This is why people with very large savings accounts sometimes move money to accounts that earn little or no interest if they are trying to reduce their tax burden. It is also why some people look into high-yield savings accounts only if they have enough money that the extra interest outweighs the tax cost — though for most people, earning more interest is worth paying the tax on it.

Accounts that have different tax rules

Not all savings vehicles work the same way. A regular savings account at a bank or credit union is taxed as described above. But certain accounts have tax advantages built in.

A Roth IRA or Roth 401(k) allows your savings to grow without you paying tax on the interest or withdrawals in retirement. A traditional IRA or 401(k) lets you deduct contributions from your income now, and you pay tax later when you withdraw the money. A 529 college savings plan grows tax-free if you use it for education expenses.

These accounts are designed to encourage saving for specific goals. If you are saving for retirement or education, it is worth learning whether one of these accounts might reduce your tax burden. A tax preparer or financial counselor can help you understand which account type makes sense for your situation.

What to do if you did not receive a 1099-INT

If your bank did not send you a 1099-INT but you know you earned interest, check your account statements. Most banks show interest deposits monthly or quarterly. Add up all the interest deposits for the year and keep that total.

Contact your bank and ask for a statement showing the interest you earned. Many banks can provide this in writing or through your online account. If the bank says the amount was below the reporting threshold and they did not send a form, you still need to report that interest on your tax return — the IRS expects it.

When you file your return, you can enter the interest amount directly on the appropriate line, even without a 1099-INT. If you are working with a tax preparer, give them the bank statement or the amount you calculated.

State income tax on savings interest

In addition to federal income tax, most states tax interest income as well. The rules vary by state. Some states tax interest the same way the federal government does — as regular income. A few states do not tax interest income at all, or they tax it at a lower rate.

Your state tax return will ask for your interest income, usually in a section that mirrors the federal form. The 1099-INT your bank sends covers both federal and state reporting, so you use the same interest amount for both returns.

If you live in a state with no income tax — such as Florida, Texas, or Wyoming — you do not owe state tax on your savings interest, though you still owe federal tax. If you moved during the year, you may owe tax to more than one state. A tax preparer familiar with your state can walk you through this.

Frequently Asked Questions

Do I have to pay taxes on interest if I do not file a tax return?

If you are required to file a return based on your income, then yes — you must report the interest. Whether you are required to file depends on your age, filing status, and total income. The IRS website has a tool to help you determine if you need to file. If you are not required to file, you generally do not owe tax on the interest, but you may want to file anyway if taxes were withheld from other income.

Can I avoid paying taxes on savings interest by keeping the account in someone else's name?

No. The person whose name is on the account is responsible for reporting the interest, regardless of who actually owns the money. If you put money in a child's account, the child must report the interest on their return. If you put money in a spouse's account, the spouse reports it. The IRS matches 1099-INT forms to the Social Security number on the account.

What if I earned interest in multiple savings accounts?

You report all of it. Each bank sends a separate 1099-INT for accounts in your name at that bank. When you file your return, you add up the interest from all the forms and report the total. The IRS receives copies of all the forms, so they will know if you leave any out.

Does the bank take taxes out of my interest automatically?

No. The bank deposits the full interest amount into your account without withholding any tax. You pay the tax when you file your return. This is different from a paycheck, where your employer withholds taxes before you receive the money. With interest, you get all of it upfront and settle the tax bill later.

What happens if I do not report the interest on my tax return?

The IRS receives a copy of your 1099-INT from the bank and will notice if the amount does not appear on your return. This can trigger an audit or a notice asking you to explain the discrepancy. It is simpler and safer to report it when you file. If you made a mistake in a prior year, you can file an amended return to correct it.
