Interest income is taxable; the account balance itself is not

You do not pay federal income tax on the money you deposit into a savings account or the balance sitting there. You do pay tax on the interest your bank pays you. If your savings account earned $50 in interest last year, that $50 is taxable income. The $5,000 you deposited and kept in the account is not.

The bank reports this interest to you and to the IRS on a Form 1099-INT each January. You include that interest amount on your tax return as ordinary income, taxed at your regular income tax rate. The threshold for receiving a 1099-INT varies by bank but is often $10 or more in annual interest, though some banks report all interest regardless of amount.

State and local taxes follow the same rule: interest is taxable, principal is not. Some states exempt interest earned in certain savings vehicles (like state-sponsored college savings plans), but a regular savings account interest is taxable in every state that has an income tax.

Key Takeaways

  • Interest earned on your savings account is taxable income reported on Form 1099-INT, but the money you deposited is never taxed again.
  • Your bank sends you a 1099-INT in January showing the prior year's interest; you report this amount on your federal tax return.
  • Interest is taxed as ordinary income at your regular tax rate, not at a special rate.
  • State income tax applies to savings account interest in states with income tax, with rare exceptions for specific savings products.
  • If you earned less than the bank's reporting threshold (often $10), you still owe tax on that interest even if you don't receive a 1099-INT.

How the IRS learns about your interest income

Banks are required to report interest to both you and the IRS. In early January, your bank mails or emails you a Form 1099-INT showing all interest paid to your account during the prior calendar year. The bank files a copy with the IRS at the same time.

The IRS matches the 1099-INT they receive from the bank against your tax return. If you don't report the interest shown on the 1099-INT, the IRS will notice the discrepancy. This is one of the most straightforward matches the IRS makes because the numbers come directly from the bank.

Even if your interest is below the bank's reporting threshold and you don't receive a 1099-INT, you still owe tax on it. The burden is on you to report all interest income, whether or not you receive a form. However, if you earned less than $1,150 in interest (as of 2024) and have no other income, you may not be required to file a return at all—but this depends on your age and filing status.

When interest rates matter to your tax bill

Higher interest rates mean more interest income, which means a larger tax bill. When savings account rates were near zero (2010–2021), most people earned minimal interest and owed little or no tax on it. As rates rose starting in 2022, the same $10,000 account began earning $400–$500 per year instead of $5–$10, creating a real tax liability.

A high-yield savings account earning 4–5% annually will generate significantly more taxable interest than a traditional savings account earning 0.01%. If you have $50,000 in a high-yield account at 4.5%, you'll earn roughly $2,250 in interest per year—all taxable at your ordinary income rate.

This does not mean high-yield accounts are a bad choice. The interest you earn is still yours to keep after taxes. But it is worth factoring the tax cost into your decision if you're comparing account types.

Tax-advantaged alternatives to regular savings accounts

If you want to save money and minimize taxes, some accounts shield interest from federal tax or defer it:

  • Roth IRA: Interest and investment gains grow tax-free and are never taxed when you withdraw them in retirement (subject to age and contribution rules).
  • Traditional IRA: Interest grows tax-deferred; you pay tax only when you withdraw money in retirement.
  • 529 college savings plan: Interest and investment gains are tax-free if used for may have access to education expenses.
  • Health Savings Account (HSA): Interest grows tax-free if the money is used for medical expenses.
  • I Bonds (Series I Savings Bonds): Interest is exempt from state and local tax and can be deferred federally if used for education.

These accounts have contribution limits, withdrawal restrictions, or other rules. A regular savings account has none of these constraints but offers no tax shelter. The right choice depends on when you need the money and your tax situation.

Reporting interest on your tax return

When you file your federal return, you report interest income on Schedule B (if you have more than $1,500 in interest or dividends) or directly on Form 1040 (if you have $1,500 or less). You list each account's interest separately if you received multiple 1099-INTs, or you can combine them into a single line if the total is small.

The interest amount flows into your total income and is taxed at your regular rate. If you're in the 22% tax bracket, $1,000 in interest costs you roughly $220 in federal tax (before any credits or deductions). If you're in the 12% bracket, it costs roughly $120.

State returns follow a similar process. You report the same interest income on your state return (unless your state has no income tax or exempts certain interest). Some states allow you to deduct a portion of interest income if you're over a certain age or meet other conditions, but this is rare.

What happens if you don't report interest income

The IRS receives a copy of every 1099-INT your bank files. If your return shows no interest income but the IRS has a 1099-INT in your file, they will send you a notice. You'll owe the tax plus interest (currently around 8% per year) and may face a penalty of 20% of the unpaid tax if the IRS determines the underreporting was negligent.

If the underreporting is deemed intentional fraud, penalties can reach 75% of the unpaid tax. In practice, most interest-reporting mismatches are caught and corrected through automated notices, not criminal prosecution. But the cost of penalties and back interest makes it far cheaper to report the interest in the first place.

If you genuinely did not receive a 1099-INT and the interest was small, contact your bank to request a corrected form or a statement showing the interest paid. Keep records of all your account statements so you can prove what you earned if the IRS questions you.

Frequently Asked Questions

Do I owe taxes on interest if I closed the account before the end of the year?

Yes. The bank reports all interest earned during the calendar year, regardless of when you close the account. If you earned $75 in interest before closing the account in June, that $75 is taxable for that year. The bank will still send you a 1099-INT in January showing the full year's interest.

What if I have multiple savings accounts at different banks?

Each bank sends you a separate 1099-INT for its own interest. You report all of them on your tax return. If the total interest is $1,500 or less, you can combine them on one line of Form 1040. If it's more than $1,500, you list each one on Schedule B.

Is interest from a joint savings account split between the two owners for tax purposes?

Not automatically. The bank reports the full interest amount on a 1099-INT to whoever is listed as the account owner or primary holder. If the account is truly joint and you each own half, you and the other owner should work out how to split the interest income on your separate returns. The bank does not do this for you.

Do I pay taxes on money I transfer between my own savings accounts?

No. Transferring money from one account to another is not income. Only the interest the bank pays you is taxable. Moving $5,000 from savings to checking creates no tax event.

What if my savings account earned less than $1 in interest—do I still owe tax?

Technically yes, but practically it makes no difference. You owe tax on all interest income, no matter how small. However, if your total interest is less than $1,150 (as of 2024) and you have no other income, you may not be required to file a return. Check the IRS filing requirements for your age and status to be sure.
