Savings account interest counts as taxable income

Yes. The interest your bank pays you on a savings account is ordinary income, and you owe federal income tax on it. Your state may tax it too. The IRS treats it the same way it treats wages or freelance income — money that came to you, so money you report.

The amount you owe depends on your total income and your tax bracket, not on the interest amount itself. If you earned $50 in interest and you're in the 22% federal bracket, you don't automatically owe $11. You add that $50 to your other income, calculate your total tax, and pay based on where that total lands.

Your bank will report the interest to the IRS on a Form 1099-INT if you earned $10 or more in interest during the year. You'll receive a copy in January or February. Even if you earned less than $10, you still owe tax on it — the bank just won't file the form.

Key Takeaways

  • Savings account interest is taxable income at both federal and state level, reported on your tax return as ordinary income.
  • Your bank sends you a Form 1099-INT if you earned $10 or more in interest during the year, usually by January 31.
  • The tax you owe depends on your total income and tax bracket, not on the interest amount alone.
  • High-yield savings accounts earn more interest, which means more tax owed, so the after-tax return is lower than the advertised rate.
  • You report the interest on your Form 1040 or 1040-SR, on the line for interest income, when you file your return.

How the 1099-INT form works

Your bank generates a Form 1099-INT for each account that earned $10 or more in interest during the calendar year. The form shows the account number, the interest amount, and your tax ID (usually your Social Security number). The bank files a copy with the IRS and mails a copy to you.

You receive the form by January 31 of the following year. If you have multiple savings accounts at different banks, you'll receive multiple 1099-INT forms — one per bank, not one per account. Some banks combine interest from multiple accounts on a single form.

The form is informational. You don't send it with your tax return. Instead, you use the interest amount shown on it to fill in your tax return. If the amount on the 1099-INT doesn't match your records, contact the bank to request a corrected form (called a Form 1099-INT with a corrected amount).

Where you report the interest on your tax return

You report savings account interest on Form 1040 or Form 1040-SR (the standard federal income tax return). The interest goes on the line labeled "Interest" in the income section, usually near the top of the form. If you use tax software, it will ask you for the amount and place it automatically.

If your total interest income from all sources is more than $1,500, you may need to file Schedule B (Interest and Ordinary Dividends) instead of reporting the amount directly on the 1040. Tax software handles this distinction for you.

State tax returns vary. Most states that have an income tax ask you to report interest income on their version of the 1040. A few states don't tax interest income at all — check your state's tax agency website to confirm whether your state taxes savings interest.

How much tax you actually owe on the interest

The tax owed depends on your total income and which tax bracket you fall into. If you earned $100 in savings interest and your total income puts you in the 12% federal bracket, you don't owe $12 on that interest. Instead, that $100 is added to your other income, and your total tax is calculated on the combined amount.

For example: if you earned $50,000 in wages and $100 in savings interest, your taxable income is $50,100. Your tax is calculated on $50,100, not on the $100 separately. The marginal effect of that $100 depends on where $50,100 lands in the tax brackets.

High-yield savings accounts currently earn 4% to 5% annually, which means a $10,000 balance generates $400 to $500 per year in interest. If you're in the 22% bracket, that's roughly $88 to $110 in federal tax owed on that interest alone. Your actual after-tax return is closer to 3.1% to 3.9%, not the advertised rate.

Interest earned before you turn 18 or in a dependent's name

If a parent or guardian opened a savings account in a child's name, the interest is still taxable income — to the child, not the parent. The bank reports it on a 1099-INT under the child's Social Security number.

A dependent child may still need to file a tax return even if they had no wages. The threshold depends on the type and amount of unearned income (interest, dividends, capital gains). For 2024, a dependent with more than $1,300 in interest income must file a federal return. Check the IRS website for the current year's threshold, as it changes annually.

Some parents use a Coverdell Education Savings Account or 529 plan for a child's savings instead of a regular account, because the interest grows tax-deferred (you don't owe tax on it each year). These are separate accounts with different rules and tax treatment.

What happens if you don't report the interest

The IRS receives a copy of every 1099-INT your bank files. If you don't report the interest on your return, the IRS will notice the mismatch between what the bank reported and what you reported. This triggers a notice asking you to explain the difference or pay the tax owed.

If the interest was genuinely earned and you straightforward forgot to report it, you can file an amended return (Form 1040-X) to add it. You'll owe the tax plus interest on the unpaid amount, calculated from the original due date. Penalties may explore if the IRS determines the omission was intentional.

For small amounts — $50 or $100 in interest — the IRS usually doesn't pursue it aggressively, but the risk exists. It's simpler to report it when you file.

Frequently Asked Questions

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

Yes. The $10 threshold only determines whether your bank files a 1099-INT form. You still owe tax on any interest you earned, even $5 or $8. You report it on your return based on your own records or bank statements.

Can I deduct savings account fees against the interest income?

No. Interest is reported as gross income. Fees you paid to the bank are not deductible against it. You report the full interest amount and pay tax on it, even if fees reduced your net gain.

What if I moved money between banks mid-year and earned interest at both?

Each bank reports the interest it paid you on a separate 1099-INT. You add all the interest amounts together and report the total on your tax return. You'll receive multiple forms if you had accounts at multiple banks.

Does a joint savings account change how the interest is taxed?

The interest is still taxable income. If the account is jointly owned, the bank may report all the interest to one owner's Social Security number, or split it between both owners. Check your 1099-INT to see how the bank reported it, and coordinate with the other owner so you don't both report the full amount.

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

Yes. Money market accounts, certificates of deposit (CDs), and other savings products all generate interest that is taxed as ordinary income. Your bank reports it on a 1099-INT the same way.
