Your savings account interest is taxable income, but the tax you owe depends on how much interest you earned and your total income for the year

The interest your bank pays you on a savings account counts as ordinary income to the IRS, the same way wages or freelance earnings do. You report it on your federal tax return, and depending on your state, you may owe state income tax on it as well. The bank sends you a Form 1099-INT each January showing how much interest you earned in the previous year, and you use that number when you file taxes.

How much tax you actually owe on that interest depends on your tax bracket — the percentage of your income that goes to federal tax. If you earned $50 in interest and you are in the 22% tax bracket, you would owe roughly $11 in federal tax on that interest. If you earned $500 in interest and are in the 12% bracket, you would owe roughly $60. The exact amount also depends on whether you have other income, deductions, and whether you file as single, married, or head of household.

Banks are required to report interest of $10 or more on Form 1099-INT. If you earned less than $10, the bank does not have to send you a form, but you still owe tax on that interest if you file a return.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your federal tax bracket rate, plus any applicable state income tax.
  • Your bank sends Form 1099-INT in January showing the interest you earned, which you report when you file your tax return.
  • Interest under $10 does not require a Form 1099-INT, but you still owe tax on it if you file a return.
  • High-yield savings accounts earn more interest than traditional savings accounts, which means higher tax liability on that interest.
  • You can reduce taxable interest by moving money to tax-advantaged accounts like Roth IRAs or 529 plans, depending on your situation.

When the bank sends you Form 1099-INT and what to do with it

In late January or early February, your bank mails or emails you a Form 1099-INT for the previous calendar year. This form shows the total interest you earned in boxes labeled "Interest Income" (usually box 1). If you have accounts at multiple banks, you will receive a separate 1099-INT from each one.

You need this form to file your tax return. When you file, you report the total interest from all your 1099-INT forms on Schedule 1 (Form 1040), line 8b. If you use tax software, you enter the amount and the software carries it to the right place. If you file by hand or with a tax professional, give them all your 1099-INT forms.

Keep your 1099-INT forms for your records. The IRS also receives a copy, so if you do not report the interest, the IRS will likely notice the mismatch and send you a notice.

How high-yield savings accounts change your tax bill

A traditional savings account at a large bank might earn 0.01% annual interest. A high-yield savings account at an online bank might earn 4% to 5% or more. The difference in interest earned is substantial, and so is the difference in taxes owed.

If you have $10,000 in a traditional savings account earning 0.01%, you earn $1 per year in interest and owe roughly $0.12 in federal tax (at the 12% bracket). If you have the same $10,000 in a high-yield account earning 4.5%, you earn $450 per year and owe roughly $54 in federal tax. The higher the interest rate, the higher your tax liability.

This does not mean high-yield accounts are a bad choice — you are earning far more interest than you would elsewhere, and the tax is still only on the interest you actually earned. But it is worth understanding that moving to a high-yield account will increase the amount you report on your tax return.

State income tax on savings interest

Most states tax savings account interest the same way the federal government does — as ordinary income at your state tax bracket. A few states do not have income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you owe federal tax on your interest but no state tax.

If you live in a state with income tax, you report the same interest income on your state return that you reported on your federal return. Some states have lower tax brackets than the federal government, and some have higher ones. New York and California, for example, have top state tax brackets above 10%, which means interest earned there is taxed more heavily than in states with lower brackets.

A few states offer limited breaks on interest income — for example, some states exempt interest earned on certain types of savings accounts or for people over a certain age — but these are rare and usually apply only to very specific situations. Check your state's tax agency website if you want to know whether your state has any special rules.

Tax-advantaged accounts that avoid or defer interest taxation

If you want to save money without paying tax on the interest, you have several options depending on your age and income. A Roth IRA lets you save up to $7,000 per year (or $8,000 if you are 50 or older), and any interest you earn inside the account is never taxed, as long as you follow the withdrawal rules. A traditional IRA defers the tax — you do not pay tax on the interest while the money is in the account, but you pay tax on withdrawals in retirement.

A 529 college savings plan works similarly to a Roth IRA: interest earned inside the account is not taxed as long as you use the money for may have access to education expenses. If you have children or grandchildren, this can be a way to save for their education without paying tax on the interest.

A Health Savings Account (HSA) also grows tax-free if you have a high-deductible health plan. You can save money for medical expenses, and the interest is never taxed.

These accounts have contribution limits and rules about when you can withdraw the money, so they are not right for everyone. But if you have money you plan to save for retirement, education, or medical expenses, moving it to one of these accounts can eliminate the tax on interest entirely.

What happens if you do not report savings interest on your tax return

The IRS receives a copy of every Form 1099-INT your bank sends you. If you do not report the interest on your tax return, the IRS will eventually notice that the 1099-INT does not match your return. You will receive a notice asking you to explain the discrepancy or pay the tax you owe plus penalties and interest.

The penalty for not reporting income is usually 20% of the unpaid tax, plus interest that accrues daily. If the IRS determines the failure was intentional, the penalty can be as high as 75%. It is far cheaper to report the interest, even if it means paying tax on a small amount.

If you genuinely did not receive a 1099-INT and the bank did not send one (which should only happen if you earned less than $10), you can still report the interest based on your own records. Most banks let you download a statement showing interest earned, which you can use as documentation if the IRS questions you.

Frequently Asked Questions

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

The bank does not have to send you a Form 1099-INT if you earned less than $10, but you still owe tax on that interest if you file a return. You can find the exact amount on your bank statement and report it on your tax return.

Can I deduct the tax I pay on savings interest?

No. Interest income is taxable, and there is no deduction that offsets it. You report the interest as income and pay tax at your regular rate. You cannot deduct investment expenses or the tax itself.

What if I have multiple savings accounts at different banks?

Each bank sends you a separate Form 1099-INT. You add up all the interest from all your accounts and report the total on your tax return. The IRS receives copies of all the forms, so they will see the total anyway.

Does moving money between my own savings accounts count as income?

No. Transferring money from one account to another is not income — it is just moving your own money around. Only the interest the bank pays you is taxable.

If I close a savings account mid-year, do I still owe tax on the interest?

Yes. You owe tax on all interest earned during the year, regardless of when you close the account. The bank will report the interest on your 1099-INT, and you report it on your tax return.
