Savings account interest is taxed as ordinary income, not capital gains

The interest your bank pays you on a savings account is treated as ordinary income by the IRS, the same way wages or salary are taxed. It is not taxed as capital gains. This matters because ordinary income tax rates are usually higher than capital gains rates, and you owe tax on the interest even if you never withdraw the money from the account.

The bank reports this interest to you and the IRS on a form called a 1099-INT (Interest Income). You receive this form by January 31 each year for any interest earned in the previous year. Even if the bank does not send you the form, you still owe tax on the interest — the form is just documentation.

The amount of interest that gets taxed depends on your account balance and the interest rate your bank offers. Interest rates on savings accounts vary widely by bank and change over time, so the amount you owe in taxes will be different each year.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your regular tax rate, not at the lower capital gains rate.
  • Your bank sends you a 1099-INT form by January 31 showing the interest you earned in the previous year, which you report on your tax return.
  • You owe tax on interest even if you leave the money in the account and never withdraw it.
  • The tax you owe depends on your total income for the year, because higher earners pay a higher percentage in taxes.
  • Some savings accounts, like those in an IRA or 401(k), let your interest grow without triggering annual taxes until you withdraw the money.

Why interest is not capital gains

Capital gains are profits you make when you sell an asset — like a stock or a house — for more than you paid for it. Interest is different: it is money the bank pays you straightforward for letting them use your money. Because interest is payment for a service (the use of your funds), not a profit from selling something, the IRS treats it as regular income.

This distinction matters for your tax bill. Capital gains have their own tax rates, which are often lower than ordinary income rates. Long-term capital gains (assets held over one year) can be taxed at 0%, 15%, or 20% depending on your income. Ordinary income, including savings interest, is taxed at rates ranging from 10% to 37%. So the same dollar amount of interest will usually cost you more in taxes than the same dollar amount of capital gains would.

How the 1099-INT form works

At the end of each calendar year, your bank calculates all the interest paid to your accounts and sends you a 1099-INT form. This form shows the total interest earned. You receive it by January 31 of the following year. If you have accounts at multiple banks, you will receive a separate 1099-INT from each one.

When you file your tax return, you report the amount from the 1099-INT on your Form 1040 (the main individual tax return form) or Schedule B if you have interest income from multiple sources. The IRS receives a copy of your 1099-INT directly from the bank, so they know how much interest you earned. If you do not report it on your return, the IRS will likely notice the mismatch.

If your total interest income is less than $10 in a year, the bank may not send you a 1099-INT, but you still owe tax on that interest if you are required to file a return.

When you owe tax on interest you have not withdrawn

You owe tax on savings interest in the year it is earned, even if the money stays in your account. This is called accrual basis taxation. If your account earned $50 in interest in 2024, you owe tax on that $50 in 2024, regardless of whether you withdrew it or left it in the account to earn more interest.

This is different from how some investments work. With certain types of accounts or investments, you can defer taxes until you actually withdraw the money. But with a regular savings account, the interest is taxable in the year it is credited to your account.

Tax-advantaged accounts where interest is not when ready taxed

Some types of accounts let your savings interest grow without triggering annual taxes. The most common are IRAs (Individual Retirement Accounts) and 401(k) plans offered by employers. Inside these accounts, interest compounds year after year without you owing tax on it until you withdraw the money in retirement.

A traditional IRA or traditional 401(k) defers taxes until withdrawal. A Roth IRA or Roth 401(k) lets the interest grow tax-free permanently if you follow the withdrawal rules. High-yield savings accounts (HYSAs) are regular savings accounts, not retirement accounts, so interest earned in them is taxed annually like any other savings account.

If you are earning significant interest on a regular savings account, moving some money to a tax-advantaged account might reduce your annual tax bill. A tax professional can advise whether this makes sense for your situation.

How your tax bracket affects what you owe

The amount of tax you pay on savings interest depends on your total income for the year and your tax bracket. Your tax bracket is the percentage rate applied to your income. If you earn $50,000 in wages and $500 in savings interest, that $500 is taxed at your marginal rate — the rate that applies to your highest dollars of income.

For 2024, tax brackets range from 10% to 37% depending on filing status and total income. A person in the 22% bracket pays 22 cents in federal tax for every dollar of interest earned. Someone in the 37% bracket pays 37 cents per dollar. State and local income taxes may explore on top of federal tax, depending on where you live.

This is why high-yield savings accounts, which pay more interest, can push you into a higher tax bracket if you have a large balance. The interest itself is not taxed differently, but earning more of it can increase your overall tax bill.

Reporting interest on your tax return

When you file your federal tax return, you report interest income on Form 1040, Schedule B (if you have more than $1,500 in interest income) or directly on the main form (if you have less). You enter the total from your 1099-INT form or forms.

If you have interest income but did not receive a 1099-INT (for example, if the amount was under $10 or the bank made an error), you still report the interest on your return. Keep your own records of interest earned so you can report it accurately.

State tax returns work similarly. Most states tax interest income as ordinary income. A few states do not tax income at all, so if you live in one of those states, you would owe federal tax on the interest but not state tax. Check your state's tax rules or consult a tax professional if you are unsure.

Frequently Asked Questions

Do I owe taxes on interest if I do not withdraw the money?

Yes. You owe federal income tax on savings interest in the year it is earned, whether you withdraw it or leave it in the account. The bank credits the interest to your account, and that is when it becomes taxable income.

What if my savings account earned less than $10 in interest?

You still owe tax on it, but the bank may not send you a 1099-INT. Keep your own records and report the interest on your tax return if you are required to file one. The amount is small, but the IRS expects accuracy.

Is interest from a money market account taxed differently?

No. Money market accounts are savings accounts, so interest is taxed as ordinary income just like a regular savings account. The bank reports it on a 1099-INT the same way.

Can I deduct savings account interest as a loss?

No. Interest income is taxable, but you cannot deduct it as a loss. You report the full amount earned on your tax return.

Does a high-yield savings account get taxed differently?

No. High-yield savings accounts pay more interest, so you owe more tax on the interest, but the interest itself is taxed as ordinary income like any other savings account. The higher rate does not change the tax treatment.
