The IRS taxes savings account interest as ordinary income in the year you earn it

Interest you earn in a high interest savings account is taxed by the federal government as ordinary income, the same way wages are taxed. The bank reports what you earned to the IRS on a Form 1099-INT, and you report that same amount on your tax return. There is no special rate or exemption for savings interest — it uses your regular income tax bracket, whether that is 10%, 22%, 24%, or higher.

The tax is owed in the year the interest posts to your account, even if you do not withdraw the money. If your account earned $500 in interest during 2024, you owe tax on that $500 when you file your 2024 return in 2025, regardless of whether the money is still sitting in the account.

State and local taxes also apply in most places. If you live in a state with income tax, you will owe state tax on the interest as well. A few states — including Florida, Texas, and Wyoming — have no state income tax, so residents there owe only federal tax on savings interest.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your federal tax bracket, not at a reduced rate.
  • The bank sends you a Form 1099-INT by January 31 showing how much interest you earned, and you report that amount on your tax return.
  • You owe tax on interest in the year it is credited to your account, even if you leave the money untouched.
  • State income tax applies to savings interest in most states, adding to your federal tax bill.
  • Interest earned in tax-advantaged accounts like Roth IRAs or 529 plans is not taxed the same way and follows different rules.

When the bank reports your interest to the IRS

Banks send Form 1099-INT to both you and the IRS by January 31 of the following year. This form lists all the interest you earned in that account during the previous calendar year. If you have multiple savings accounts at different banks, you will receive a separate 1099-INT from each bank.

If you earned less than $10 in interest during the year, the bank may not be required to send you a 1099-INT, but you still owe tax on that interest. You report it on your return even without the form. If you earned $10 or more, the bank must send the form.

The 1099-INT shows the interest amount in Box 1. Some banks also report other types of interest (such as interest from bonds or CDs) in different boxes, but savings account interest goes in Box 1. You use this number when you fill out your tax return, typically on Schedule B if you have more than $1,500 in interest income.

How your tax bracket determines what you actually pay

The amount of tax you owe depends on your total income and your tax filing status. A person in the 12% federal tax bracket pays 12 cents in federal tax for every dollar of interest earned. Someone in the 35% bracket pays 35 cents per dollar. The interest is added to your other income — wages, self-employment income, investment gains — and taxed at whatever rate applies to your total.

This means a high interest savings account earning 4.5% APY is not actually earning 4.5% after tax. If you are in the 24% federal bracket and your state has a 5% income tax, your real after-tax return is closer to 3.2%. The higher your tax bracket, the more the interest is reduced by taxes.

You can estimate your after-tax return by multiplying the APY by (1 minus your combined federal and state tax rate). If your combined rate is 29% and the account pays 4.5%, your after-tax return is roughly 4.5% × 0.71 = 3.2%.

Interest in tax-advantaged accounts works differently

If you hold a high interest savings account inside a Roth IRA, the interest is not taxed at all, ever. You pay no federal or state tax on the earnings, and you do not report them on your return. The same applies to interest earned in a traditional IRA — it grows tax-deferred, meaning you do not pay tax until you withdraw the money in retirement.

A 529 college savings plan also allows interest to grow tax-free if the money is used for may have access to education expenses. If you withdraw it for other purposes, the earnings portion becomes taxable.

These accounts have contribution limits and withdrawal rules, so they are not a replacement for a regular savings account. But if you have money you are saving for retirement or education, using a tax-advantaged account can significantly reduce the tax bite on your interest earnings.

What happens if you do not report the interest

The IRS receives a copy of every 1099-INT the bank sends to you. If you do not report the interest on your return, the IRS will notice the discrepancy and may send you a notice asking for the missing income and any tax owed, plus penalties and interest charges. The penalty for not reporting income is usually 20% of the unpaid tax, and interest accrues on top of that.

Even small amounts matter. If you earned $50 in interest and did not report it, and you are in the 24% bracket, you owe $12 in federal tax plus state tax. If caught, you might owe that $12 plus a $2.40 penalty plus interest — a total of roughly $15 or more depending on how long it goes unreported.

The easiest approach is to report the interest when you file. Most tax software automatically pulls the 1099-INT information if you provide your bank account details, or you can enter it manually.

Strategies to reduce the tax on savings interest

One option is to keep money you are saving for retirement or education in a tax-advantaged account rather than a regular savings account. The tax savings can be substantial over time, especially if the account earns interest for decades.

Another approach is to be intentional about which accounts hold which money. If you have a large emergency fund that you do not need for retirement, a regular high interest savings account makes sense. But if you have money earmarked for a child's education or your own retirement, a 529 plan or IRA will reduce your tax bill.

You can also consider the timing of large deposits. If you are about to receive a bonus or inheritance, depositing it in December versus January changes which tax year the interest is reported in. This rarely makes a huge difference, but it can matter if you are close to a tax bracket boundary.

Some people use a money market account or certificate of deposit (CD) instead of a savings account, thinking it will be taxed differently. It is not — interest from CDs and money market accounts is also taxed as ordinary income and reported on a 1099-INT.

State taxes on savings interest vary widely

Most states tax savings account interest as part of your regular income. The state tax rate varies from roughly 1% to 13% depending on where you live and your income level. A few states have no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming.

Some states offer small exemptions for interest income. For example, a handful of states exempt interest earned by people over a certain age, or exempt interest below a certain threshold. These exemptions are rare and usually modest, so they should not drive your decision about where to keep your savings.

If you live in a high-tax state and move to a low-tax state, your tax situation changes starting in the year you move. The state where you lived for most of the year is where you owe tax on the interest earned that year.

Frequently Asked Questions

Do I have to pay tax on interest if I do not withdraw the money?

Yes. Tax is owed on interest in the year it is credited to your account, whether you withdraw it or leave it to compound. The IRS considers the interest income in the moment the bank adds it to your balance, not when you spend it.

What if I earned less than $10 in interest?

You still owe tax on it, but the bank may not send a 1099-INT. You report the interest on your return anyway. If you earned $10 or more, the bank must send the form.

Can I deduct savings account interest as a loss?

No. Interest income cannot be deducted. You report it as income and pay tax on it. You cannot offset it with other losses unless those losses are investment losses from stocks or bonds, and even then the rules are strict.

Is interest from a money market account taxed differently?

No. Money market accounts, CDs, and savings accounts are all taxed the same way — as ordinary income reported on a 1099-INT. The account type does not change the tax treatment.

What if the bank reports the wrong amount on the 1099-INT?

Contact the bank and ask them to issue a corrected form. If the error is small, you can report the correct amount on your return and keep a copy of your bank statements as documentation. If the IRS questions it, you can show proof of what you actually earned.
