Yes, CD interest is taxed as ordinary income in the year you earn it

The interest your CD earns is subject to federal income tax, and in most states, state income tax as well. The IRS treats CD interest the same way it treats interest from a savings account or money market fund — as ordinary income taxed at your regular tax rate, not at the lower capital gains rate.

You owe tax on the interest even if you don't withdraw it from the CD. If your CD automatically reinvests interest, you still report that interest as income for the tax year it was earned, even though the money stayed in the account. This is one of the key differences between CDs and some other investments.

The financial institution holding your CD will send you a Form 1099-INT each January showing how much interest the CD earned in the previous year. You use that form to report the income on your tax return.

Key Takeaways

  • CD interest is taxed as ordinary income at your full tax rate, not at capital gains rates.
  • You owe tax on interest in the year it is earned, even if you leave the money in the CD and don't withdraw it.
  • Your CD provider sends you a Form 1099-INT showing the interest earned, which you report on your tax return.
  • Early withdrawal penalties are tax-deductible, which can offset some of the tax burden if you break a CD before maturity.
  • CDs held in tax-advantaged accounts like IRAs or 401(k)s are not taxed until you withdraw the money in retirement.

When you report CD interest on your tax return

You report CD interest on your federal tax return for the tax year in which the interest was earned, regardless of when you actually receive or withdraw the money. If a CD earns $500 in interest during 2024, you report that $500 on your 2024 tax return, even if you don't touch the account until 2025.

The Form 1099-INT arrives by January 31 of the following year. If you earned more than $10 in interest from all sources combined, the bank is required to send you this form. You should receive a copy for your records and a copy that goes to the IRS, so the agency already knows about your interest income.

If you earned less than $10 in interest, the bank may not send a 1099-INT, but you still owe tax on that interest if you have any tax liability. Report it on Schedule B of Form 1040 if you earned interest from more than one source, or directly on the 1040 if it's your only interest income.

How tax brackets affect what you actually owe

The tax rate on your CD interest depends on your overall income and tax bracket. If you're in the 22% tax bracket, each dollar of CD interest adds to your taxable income and is taxed at 22%. If you're in the 12% bracket, it's taxed at 12%. This is different from long-term capital gains, which have their own lower tax rates.

CD interest can also push you into a higher tax bracket. If you're close to the edge of a bracket and earn significant CD interest, that interest might be taxed at a higher rate than your other income. For example, if you earn $45,000 in wages and your CD earns $8,000 in interest, the first portion of that interest might be taxed at your current rate, but the remainder could be taxed at the next bracket's rate.

State income tax works the same way. Most states tax CD interest as ordinary income at your state tax rate. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax at all, so residents of those states owe only federal tax on CD interest.

Early withdrawal penalties and tax deductions

If you withdraw money from a CD before the maturity date, the bank charges an early withdrawal penalty. This penalty is deductible from your taxable income, which means it reduces the amount of CD interest you actually owe tax on.

Here's how it works: suppose your CD earned $1,000 in interest, but you withdrew the money early and paid a $150 penalty. You report the full $1,000 on your 1099-INT, but you can deduct the $150 penalty on your tax return. Your taxable interest income becomes $850 instead of $1,000. The bank will show the penalty separately on your 1099-INT, usually labeled as "interest forfeited due to early withdrawal" or similar language.

This deduction doesn't eliminate the tax burden entirely, but it does reduce it. In a 22% tax bracket, a $150 penalty deduction saves you about $33 in federal tax.

CDs in retirement accounts are taxed differently

If you hold a CD inside a traditional IRA or 401(k), the interest is not taxed in the year it's earned. Instead, you defer all taxes until you withdraw money from the account in retirement. At that point, the entire withdrawal — including the original CD money and all accumulated interest — is taxed as ordinary income.

A CD in a Roth IRA works differently again. Interest earned in a Roth CD is never taxed, as long as you follow the withdrawal rules (you must be at least 59½ and the account must be open for at least five years). This makes Roth CDs particularly valuable for people who expect to be in a higher tax bracket in retirement.

CDs in health savings accounts (HSAs) also grow tax-free, and withdrawals for may have access to medical expenses are not taxed. This is another way to hold a CD without owing annual tax on the interest.

Strategies to reduce CD interest taxes

One approach is to ladder your CDs — buy several CDs with different maturity dates rather than one large CD. This spreads the interest income across multiple years, which can keep you in a lower tax bracket each year. For example, instead of buying one $50,000 CD earning $2,000 in year one, you might buy five $10,000 CDs maturing in years one through five, earning $400 per year.

Another strategy is to hold CDs in tax-advantaged accounts when possible. If you have room in an IRA or 401(k), a CD there grows without annual tax consequences. This is especially useful if you're in a high tax bracket or if the CD interest would push you into a higher bracket.

You can also consider the timing of CD purchases. If you're near the end of a tax year and expect a large CD interest payment, you might delay buying the CD until January to spread the interest across two tax years instead of concentrating it in one.

What happens if you don't report CD interest

The IRS receives a copy of every 1099-INT sent to you. If you don't report the interest on your tax return, the IRS will notice the discrepancy and may send you a notice asking for the unpaid tax, plus interest and penalties. The penalty for not reporting income is typically 20% of the unpaid tax, plus interest that compounds daily.

Even small amounts of unreported interest can trigger an audit or correspondence. It's not worth the risk. If you receive a 1099-INT, report it, even if the amount is small or even if you think you shouldn't owe tax for some reason. If you believe there's an error on the form, contact the bank and ask them to issue a corrected 1099-INT.

Frequently Asked Questions

Do I owe tax on CD interest if I reinvest it instead of withdrawing it?

Yes. The IRS taxes interest in the year it is earned, regardless of whether you withdraw it, leave it in the account, or reinvest it. If your CD automatically reinvests interest, you still report that interest as income on your tax return for that year.

What's the difference between CD interest and capital gains tax?

CD interest is taxed as ordinary income at your full tax rate. Long-term capital gains (from stocks or mutual funds held over a year) are taxed at lower rates: 0%, 15%, or 20% depending on your income. This is why CDs are less tax-efficient than some other investments, especially for high earners.

Can I avoid taxes on a CD by putting it in someone else's name?

No. The person whose Social Security number is on the account is responsible for reporting the interest income, regardless of who owns the money. If you put a CD in your child's name, your child reports the interest. If you put it in a trust, the trust reports it.

Do I owe tax on CD interest if I'm retired and don't work?

You owe tax on CD interest if your total income exceeds the standard deduction for your filing status, even if you're retired and have no wages. In 2024, the standard deduction is $14,600 for single filers and $29,200 for married filing jointly. If your CD interest plus other income exceeds these amounts, you owe federal tax.

What if my CD earned interest but I lost money overall because of a penalty?

You still owe tax on the interest earned. The early withdrawal penalty is deductible, which reduces your taxable interest, but you can't deduct more than the interest you earned. If your CD earned $500 and the penalty was $600, you report $500 in interest and deduct $500 in penalty, resulting in zero taxable interest from the CD.
