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

The interest your bank pays you on a savings account is taxable income. The IRS treats it the same way it treats wages or investment dividends — you report it on your tax return and pay tax on it at your ordinary income tax rate. 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.

The amount of tax you owe depends on your total income and tax bracket, not on the size of the account. A person in the 22% tax bracket who earns $500 in savings interest will owe roughly $110 in federal tax on that interest. Someone in the 12% bracket earning the same $500 will owe roughly $60. State income tax, where it exists, works the same way — your state taxes the interest at your state income tax rate.

The one exception is interest earned in a Roth IRA or traditional IRA. Money in these accounts grows tax-free while it sits there, though the rules for withdrawing it vary by account type. For ordinary savings accounts, checking accounts, and money market accounts held outside an IRA, you pay tax on the interest every year, whether or not you withdraw it.

Key Takeaways

  • Your bank reports savings interest to the IRS on Form 1099-INT, which you receive by January 31 each year.
  • You owe federal income tax on all savings interest at your ordinary tax rate, plus state income tax in most states.
  • The tax is due even if you do not withdraw the interest — it is added to your account but still counts as taxable income.
  • Interest earned inside an IRA (traditional or Roth) is not taxed while the money stays in the account, though withdrawal rules differ between account types.
  • High-yield savings accounts earn more interest than traditional savings accounts, which means more tax owed, but the after-tax return is usually still higher.

When your bank sends the 1099-INT form

Your bank mails or makes available a Form 1099-INT by January 31 each year for any account that earned $10 or more in interest during the previous calendar year. If you have multiple savings accounts at the same bank, the interest from all of them is combined on a single form. If you have accounts at different banks, each bank sends its own form.

You do not have to do anything to receive the form — your bank sends it automatically if you earned enough interest. You will also receive a copy for your records. The form shows the account number, the total interest earned, and any federal tax already withheld (which is rare for savings accounts but common for other types of accounts).

When you file your tax return, you report the interest amount from the 1099-INT on Schedule 1 (Form 1040), which feeds into your total income. The IRS also receives a copy of your 1099-INT, so they know how much interest you earned. If you do not report it and the IRS finds out, you will owe the tax plus penalties and interest.

How much tax you actually owe on the interest

The tax on savings interest is calculated at your marginal tax rate — the tax bracket you fall into based on your total income for the year. If you earned $50,000 in wages and $500 in savings interest, your total taxable income is $50,500, and the $500 is taxed at whatever rate applies to that portion of your income.

Federal tax brackets change each year and depend on your filing status (single, married filing jointly, head of household, and so on). For 2024, a single person in the 22% bracket pays 22 cents in federal tax on each dollar of interest. A married couple filing jointly in the 12% bracket pays 12 cents per dollar. Your state income tax rate is separate and varies by state — some states have no income tax at all, while others tax interest at rates ranging from roughly 3% to 13%.

The actual amount you owe is straightforward math: interest earned × your tax rate. If you earned $1,000 in interest and your combined federal and state rate is 25%, you owe $250 in tax. That $250 comes out of your pocket when you file your return, unless you had enough tax withheld from wages during the year to cover it.

Why high-yield savings accounts still make sense despite the tax

A high-yield savings account currently earns roughly 4% to 5% annual interest, compared to 0.01% or less at a traditional savings account. That difference sounds small until you do the math: $10,000 in a high-yield account earns $400 to $500 per year, while the same amount in a traditional account earns $1. Even after paying tax on the interest, you come out far ahead.

The tax is owed on the interest you earn, not on the account balance itself. Your $10,000 principal is never taxed — only the $400 or $500 it generates. If your tax rate is 25%, you owe $100 to $125 in tax, leaving you with $275 to $375 in after-tax interest. That is still vastly better than the $0.75 you would keep from a traditional savings account.

The only time the tax becomes a real drawback is if you are in a very high tax bracket (35% or more combined federal and state) and the interest is substantial enough to push you into a higher bracket. For most people, the higher interest rate more than compensates for the tax owed.

Tax-advantaged alternatives for larger savings

If you have a significant amount saved and want to avoid or defer taxes on the growth, a traditional IRA or Roth IRA lets you hold a savings account or money market fund inside it. Interest earned inside the IRA is not taxed each year — it compounds tax-free. When you withdraw the money, the tax treatment depends on the account type.

In a traditional IRA, you do not pay tax on the interest while it grows, but you pay ordinary income tax on the full amount you withdraw in retirement. In a Roth IRA, you do not pay tax on the interest while it grows, and you do not pay tax on withdrawals in retirement, as long as the account has been open for at least five years and you are at least 59½ years old. Both accounts have annual contribution limits (currently $7,000 for people under 50, $8,000 for people 50 and older) and rules about when you can withdraw without penalty.

For amounts above the IRA limit, a regular taxable savings account is your only option. There is no way to avoid the annual tax on interest in a non-IRA account, but the interest itself is still income you want to earn.

What happens if you do not report the interest

The IRS receives a copy of every 1099-INT your bank sends. If you do not report the interest on your tax return and the amount is more than a few dollars, the IRS will eventually notice the discrepancy. They will send you a notice asking for the tax owed, plus penalties (usually 20% of the unpaid tax) and interest on the unpaid amount, compounded daily.

The penalty and interest can easily double what you owed in the first place. If you owed $100 in tax and ignored the notice for two years, you might end up owing $250 or more. The safest approach is to report the interest when you file, even if it is a small amount.

If you realize you missed reporting interest in a prior year, you can file an amended return (Form 1040-X) for that year. The sooner you do this, the lower the penalties will be. The IRS has a statute of limitations of three years for most tax matters, meaning they can go back three years to assess tax and penalties, though in cases of fraud or substantial underreporting, the window is longer.

Frequently Asked Questions

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

Your bank does not send a 1099-INT for interest under $10, but you still owe tax on it. If you earned $8 in interest across multiple accounts, you should report it on your return. The IRS may not catch small amounts, but the tax is legally owed.

What if I earned interest in a joint account with someone else?

The bank reports the full interest amount to the IRS, but you and the other account holder can split the income on your separate returns if you own the account jointly. You will each receive a 1099-INT showing your portion, or you may need to file amended returns to split it correctly. Talk to the bank about how they are reporting it before you file.

Can I deduct savings account fees from the interest income?

No. Savings account fees are not deductible. You report the full interest amount as income and pay tax on it, even if the bank charged you fees that reduced your net earnings.

Is interest from a money market account taxed the same way as a savings account?

Yes. Money market accounts are treated identically to savings accounts for tax purposes. The bank sends a 1099-INT, and you report the interest as ordinary income at your tax rate.

What if I closed the account partway through the year?

You still owe tax on all interest earned up to the date you closed it. The bank will report the interest on the 1099-INT for that year, and you report it on your return even though the account no longer exists.
