You owe federal income tax on savings account interest, and possibly state income tax too

Any interest your savings account earns counts as taxable income. The bank reports it to the IRS on a Form 1099-INT, and you report it on your tax return. The amount you owe depends on your total income for the year and your tax bracket — not on how much interest you earned.

You do not pay tax on the money you put into the account, only on the interest it generates. If you earned $50 in interest, that $50 is what gets taxed. The rate you pay on that $50 varies: it could be 10 percent, 22 percent, 24 percent, or higher, depending on your other income and filing status.

Most savings accounts earn so little interest that the tax bill is small. But if you have a high-yield savings account, a money market account, or a large balance, the interest can add up quickly — and so can the tax.

Key Takeaways

  • Banks report savings interest to the IRS on Form 1099-INT if you earned $10 or more in a calendar year.
  • You report this interest on your federal tax return as ordinary income, taxed at your marginal tax rate.
  • Most states tax savings interest the same way as the federal government, but a few states do not tax interest income at all.
  • You may owe estimated quarterly taxes if your interest income is large enough, though most savers do not reach that threshold.

When the bank sends you a 1099-INT form

Banks must send you a Form 1099-INT by January 31 of the year after you earned the interest. You get one copy, and the IRS gets another. The form shows the total interest paid to you during the calendar year.

The bank only sends the form if you earned $10 or more in interest during the year. If you earned less than $10, the bank does not have to report it — but you still owe tax on it if you file a return. Some banks send the form even when interest is under $10, so check your mail carefully.

If you had multiple accounts at the same bank, the interest from all of them may appear on a single 1099-INT. If you banked at different institutions, you will receive a separate form from each one.

How to report interest income on your tax return

When you file your federal return, you report the interest shown on your 1099-INT on Schedule B (if you have investment income) or directly on Form 1040 (if you only have interest and wages). The exact line depends on the form version your tax software or preparer uses.

The interest gets added to your other income for the year. If you earned $45,000 in wages and $200 in savings interest, your taxable income is $45,200. That extra $200 is taxed at your marginal rate — the rate that applies to your highest dollars of income.

If you earned interest from multiple banks, add all of it together on one line of your return. You do not file separate returns or forms for each account.

Your tax rate depends on your total income, not the interest amount

The tax you pay on savings interest is not a flat percentage. Instead, it depends on your tax bracket for the year. If you are in the 22 percent bracket, you pay 22 cents on every dollar of interest. If you are in the 12 percent bracket, you pay 12 cents.

Your bracket is determined by your total income — wages, self-employment income, investment income, and interest all count. A person earning $30,000 in wages and $500 in interest pays tax on the $500 at a lower rate than someone earning $100,000 in wages and the same $500 in interest.

Federal tax brackets change every year and depend on your filing status (single, married filing jointly, head of household, and so on). The IRS publishes new brackets each January.

State income tax on savings interest

Most states tax savings interest the same way the federal government does — as ordinary income at your state tax rate. A few states do not tax interest income at all. These include Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire and Tennessee tax only interest and dividend income, not wages.

If you live in a state that taxes interest, you report it on your state return using the same 1099-INT form. The state tax rate is usually lower than the federal rate but varies by state and income level.

If you moved during the year or earned interest in a state where you do not live, the rules get more complex. Some states tax interest earned within their borders even if you do not live there. Check your state's tax agency website or ask a tax preparer if you are unsure.

When you might owe estimated quarterly taxes

If your interest income is large enough that you do not have taxes withheld from it, you may need to pay estimated quarterly taxes to avoid a penalty. This usually only applies if you expect to owe $1,000 or more in federal taxes for the year and have no employer withholding.

Most people with savings accounts do not earn enough interest to trigger this rule. But if you have a very large balance in a high-yield account, or if you also have other income with no withholding, you might. The IRS provides Form 1040-ES to calculate whether you need to pay quarterly.

Quarterly payments are due April 15, June 15, September 15, and January 15. If you miss a payment, you may owe a penalty even if you pay all your taxes by April 15 of the following year.

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

If you earned $10 or more in interest but did not receive a 1099-INT by February 15, contact your bank. Ask them to send you a copy or provide the interest amount so you can report it yourself. Do not skip reporting the interest just because you did not get the form — the IRS has a copy too.

If the bank cannot locate the form or gives you a different amount than what you expected, ask for an explanation. Sometimes interest is credited in one year but reported in another, or the bank may have made an error. Get it in writing so you have proof if the IRS questions your return later.

If you find an error on a 1099-INT after you have filed your return, you can file an amended return using Form 1040-X. You have three years from the original due date to amend.

Frequently Asked Questions

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

Technically yes — any interest you earn is taxable income. But the bank does not have to send you a 1099-INT unless you earned $10 or more. If you earned less, you can report it on your return if you file one, or you may not need to file at all depending on your total income.

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

No. You report the full interest amount on your tax return. You cannot subtract fees, minimum balance penalties, or other charges. However, investment-related fees may be deductible in some cases — ask a tax preparer if you have significant fees.

What if I closed my account partway through the year?

The bank reports all interest earned during the calendar year, whether the account was open at year-end or not. If you closed the account in June, the 1099-INT will show interest earned from January through June. You report it the same way as any other interest.

Do I owe tax on interest I did not withdraw?

Yes. You owe tax on interest the moment it is credited to your account, even if you never withdraw it. The IRS taxes it as income in the year it was earned, not when you spend or move the money.

What if my interest income pushes me into a higher tax bracket?

It depends on how much interest you earned and your other income. Interest is added to your total income, so it can push you into a higher bracket. This is rare for savings accounts but more common with investment income. A tax preparer can show you the exact impact before you file.
