You pay taxes on interest your savings account earns, not on the money you deposited

The money you put into a savings account is yours—you do not owe taxes on it. But the interest the bank pays you is income, and the IRS treats it like any other income you receive. If your account earned $10 in interest last year, that $10 is taxable. The original $1,000 you deposited stays yours, tax-free.

How much you actually owe depends on your total income for the year and your tax bracket. A person earning $30,000 a year pays tax on savings interest at a different rate than someone earning $150,000. The bank does not decide your tax bill—they just report what you earned, and you report it when you file.

Key Takeaways

  • Interest earned in a savings account counts as taxable income; the principal amount you deposited does not.
  • Banks report interest of $10 or more on a Form 1099-INT, which you receive by January 31 and must report on your tax return.
  • You owe federal income tax on all interest, and state income tax on it as well if your state has an income tax.
  • High-yield savings accounts earn more interest, which means a larger tax bill, but the after-tax return is usually still better than a traditional savings account.

How the IRS finds out about your interest income

Banks report interest to the IRS automatically using a Form 1099-INT. If your account earned $10 or more in a calendar year, the bank sends you a copy by January 31 and sends a copy to the IRS at the same time. You then report that interest on your tax return when you file.

If you earned less than $10, the bank may not send a 1099-INT, but you still owe tax on the interest. You are responsible for reporting it even if the bank does not report it to the IRS. The IRS cross-checks 1099 forms against tax returns, so unreported interest on a larger account will likely be caught.

Some banks offer multiple savings products—a regular savings account, a money market account, a certificate of deposit. Each one that earns interest will show up on a separate 1099-INT or be combined on a single form, depending on the bank. Check the form carefully to make sure all your accounts are listed.

What tax rate applies to your savings interest

Savings interest is taxed as ordinary income, meaning it is taxed at the same rate as wages, salary, or other income you receive. If you are in the 22% federal tax bracket, your savings interest is taxed at 22%. If you are in the 12% bracket, it is taxed at 12%.

Your tax bracket depends on your total income for the year—not just your savings interest. A person with $35,000 in wages plus $200 in savings interest pays tax on the full $35,200 at their applicable rate. The interest does not push you into a higher bracket by itself unless your total income crosses a threshold.

If you live in a state with an income tax, you owe state tax on the interest as well. The state tax rate varies by state and by your income level. Nine states have no income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only interest and dividends, not wages).

Why high-yield savings accounts still make sense despite taxes

A high-yield savings account might earn 4% to 5% interest, while a traditional savings account at a large bank earns 0.01% to 0.05%. The difference is real money. On $10,000, a high-yield account earning 4.5% generates $450 in interest per year. A traditional account earning 0.01% generates $1.

Yes, you owe tax on that $450. If you are in the 22% federal bracket plus a 5% state bracket, you owe roughly $121 in combined taxes, leaving you with about $329 after tax. That is still 329 times better than the $1 you would have earned in a traditional account, even after paying taxes on it.

The math changes if you are in a very high tax bracket or if you have a large balance. Someone in the 37% federal bracket plus state tax might owe 40% or more of the interest in taxes. Even so, earning 2.7% after tax on a high-yield account usually beats earning 0.01% before tax on a traditional account.

How to report savings interest on your tax return

When you file your federal return, you report the interest on Schedule 1 (Form 1040), line 8, under "Interest." If you use tax software, you enter the amount from your 1099-INT and the software places it in the right spot. If you file by hand or work with a tax preparer, give them the 1099-INT.

If you have multiple savings accounts at different banks, each bank sends a separate 1099-INT (or combines them if they are the same bank). You add up all the interest from all the forms and report the total on Schedule 1. The IRS receives copies of all your 1099-INTs, so they know the total too.

You do not need to do anything special or file extra forms just because you have savings interest. It is a straightforward line item on your return. If you owe taxes overall, the interest is part of your taxable income. If you are due a refund, the interest reduces your refund (or increases the amount you owe, if the interest tips you into owing).

Strategies to reduce taxes on savings interest

You cannot avoid taxes on savings interest, but you can reduce how much interest you earn and therefore how much tax you owe. This sounds backwards, but it matters in specific situations. If you are close to a tax bracket threshold or a phase-out for a tax credit, earning a small amount of extra interest might cost you more in taxes than the interest is worth.

A more practical approach is to keep savings in accounts that match your timeline. Money you need within a year belongs in a high-yield savings account, where you can access it anytime. Money you will not touch for five years might belong in a certificate of deposit (CD), which often earns slightly more interest and locks the money away so you are not tempted to spend it. Both are taxed the same way, but the CD might earn enough extra interest to justify the lack of access.

If you have a very large balance and are concerned about the tax impact, a financial advisor can discuss whether other savings vehicles—like Treasury bonds or municipal bonds—might fit your situation. These are not savings accounts, but they are ways to store money safely. Municipal bonds, for example, are often exempt from federal tax and sometimes state tax, though they typically earn less interest than a high-yield savings account.

What happens if you do not report savings interest

If your bank reports interest on a 1099-INT and you do not report it on your tax return, the IRS will notice. They match 1099 forms to returns automatically. If the interest is small—$50 or $100—the IRS might send you a notice asking you to amend your return and pay the tax owed plus a small penalty. If the interest is larger or if you have a pattern of unreported income, the penalty is steeper.

Penalties for underreporting income start at 20% of the underpaid tax. If the IRS determines the underreporting was negligent, the penalty is 20%. If they determine it was fraudulent (meaning intentional), the penalty is 75%. You also owe interest on the unpaid tax, calculated from the original due date of the return.

The easiest path is to report the interest when you file. It takes one line on your return and costs nothing. The penalty for not reporting costs far more than the tax on the interest itself.

Frequently Asked Questions

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

Yes. The bank does not have to send you a 1099-INT if you earned less than $10, but you still owe tax on the interest. You are responsible for reporting all income, regardless of whether the bank reports it. However, if the amount is very small—$5 or $8—the practical risk of the IRS catching it is low, though technically you should report it.

What if I have savings accounts at multiple banks?

Each bank sends a separate 1099-INT for the interest earned in accounts at that bank. You add up all the interest from all the forms and report the total on your tax return. If you have ten accounts at ten banks, you will receive ten 1099-INTs, but you report one combined number on Schedule 1.

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

No. Transferring money from one account to another is not income. Only the interest the bank pays you is taxable. If you move $5,000 from savings to checking, that $5,000 is still yours and is not reported to the IRS as income.

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

No. You report the full interest amount on your tax return. If your bank charged you a $5 monthly fee, you cannot subtract that from the interest before reporting it. However, if the fee was large enough, you might be able to deduct it as a miscellaneous expense, though the rules for this are strict and the deduction is rarely worth pursuing.

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

It depends on how the account is titled and who actually owns the money. If the account is truly joint and both owners contributed equally, the interest is usually split equally for tax purposes, and each owner reports half on their return. If one person owns the money and the other is just an authorized user, the owner reports all the interest. The bank's 1099-INT will show the full amount; you and the co-owner work out how to split it based on actual ownership.
