Yes, you owe income tax on savings account interest

The interest your bank pays you on a savings account counts as taxable income. The IRS treats it the same way it treats wages or salary — you report it on your tax return and pay federal income tax on the full amount. Most states also tax savings interest as part of your state income tax.

Your bank will send you a Form 1099-INT each January showing how much interest you earned during the previous year. If you earned $10 or more in interest from any single bank, they are required to send this form. You use that form to report the interest on your tax return.

The tax you owe depends on your overall income and tax bracket. Someone in the 22% federal tax bracket pays roughly 22 cents in federal tax for every dollar of interest earned. Someone in the 12% bracket pays roughly 12 cents per dollar. State taxes add on top of that, and the amount varies by state.

Key Takeaways

  • Savings account interest is taxable income reported on Form 1099-INT, which your bank sends in January if you earned $10 or more.
  • You pay federal income tax at your marginal tax rate plus state income tax on the full interest amount — there is no threshold below which interest becomes tax-free.
  • High-yield savings accounts earn more interest but also generate higher tax bills, so the after-tax return matters more than the advertised rate.
  • You can reduce taxable interest by holding savings in tax-advantaged accounts like IRAs or 529 plans, though those accounts have their own rules and limits.

When your bank sends you the 1099-INT form

Banks mail Form 1099-INT by January 31 each year for the previous calendar year. If you have accounts at multiple banks, you may receive several forms — one from each institution where you earned interest.

The form shows interest earned in box 1. If you earned less than $10 in interest from a single bank, that bank is not required to send a form, but you still owe tax on that interest. You report it on your return even without the form.

If you did not receive a 1099-INT by early February, contact your bank directly. Ask them to send it or provide the interest amount so you can report it yourself. Waiting for the form is not a reason to skip reporting — the IRS has a copy too.

How to report savings interest on your tax return

On a federal return, you report interest income on Schedule B (Form 1040) if you have more than $1,500 in total interest and dividend income. If you have $1,500 or less, you can report it directly on Form 1040 line 2b without filing Schedule B.

Write the name of each bank and the interest amount from each 1099-INT. Add them up. That total goes on your return as interest income, and it increases your taxable income for the year.

State returns vary. Most states have a line for interest income on their main return form. A few states do not tax interest at all — currently Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax. If you live in one of those states, you report the interest only to the IRS.

The difference between high-yield and regular savings accounts

A regular savings account at a traditional bank might pay 0.01% annual interest. A high-yield savings account at an online bank might pay 4% to 5%. The higher rate means more money in your account — but also a larger tax bill.

If you have $10,000 in a regular account earning 0.01%, you earn $1 per year. If you have $10,000 in a high-yield account earning 4.5%, you earn $450 per year. The difference in your pocket after taxes depends on your tax bracket. In the 22% bracket, you keep $351 of that $450 (the other $99 goes to federal tax), plus you owe state tax on top.

The after-tax return still favors high-yield accounts for most people. But the advertised rate is not what you actually keep — factor in taxes when comparing accounts.

Tax-advantaged accounts that shield savings interest

Interest earned inside certain accounts does not trigger a tax bill in the year it is earned. A traditional IRA or Roth IRA can hold a savings account or money market fund, and interest grows tax-free inside the account. A 529 college savings plan also grows tax-free if used for education expenses.

These accounts have contribution limits and withdrawal rules. A traditional IRA lets you contribute up to $7,000 per year (or $8,000 if you are 50 or older), and you cannot withdraw money before age 59½ without penalty unless you meet certain exceptions. A Roth IRA has the same contribution limit but allows penalty-free withdrawals of your contributions anytime. A 529 plan has no annual contribution limit, but withdrawals for non-education expenses trigger taxes and a 10% penalty on the earnings portion.

For most people, the tax savings from these accounts outweigh the restrictions. But they are not a substitute for regular savings — they are meant for specific goals like retirement or education.

What happens if you do not report savings interest

The IRS receives a copy of every 1099-INT your bank sends. If you do not report the interest on your return, the IRS will notice the mismatch between what you reported and what the bank reported. They will send you a notice and bill you for the unpaid tax plus interest on that tax.

The penalty for not reporting interest income is usually 20% of the unpaid tax, though it can be higher if the IRS determines the error was intentional. Interest accrues on the unpaid tax at a rate set quarterly — currently around 8% per year.

If you made an honest mistake, you can file an amended return (Form 1040-X) to correct it. The sooner you do, the less interest accrues on the unpaid tax.

Frequently Asked Questions

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

Yes. The $10 threshold only determines whether your bank sends you a 1099-INT form. You still owe tax on any interest you earned, even $1 or $5. Report it on your return even if you do not have a form.

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

No. You report the full interest amount on your tax return. Fees are not deductible against interest income. However, if a fee is large enough, it may reduce your overall interest earnings, which reduces the amount you report.

What if I moved money between banks during the year?

Each bank reports only the interest earned on money held at that bank. If you moved $5,000 from Bank A to Bank B in June, Bank A reports interest for January through May, and Bank B reports interest for June through December. Add both 1099-INT forms together when you file your return.

Does a joint account change how interest is taxed?

The bank reports the full interest amount on a 1099-INT. If the account is jointly owned, you and the other owner must decide how to split the interest for tax purposes. Usually you split it based on each person's ownership stake. Whoever claims the interest on their return pays tax on it.
