Yes, the interest you earn on a CD is taxable income

The interest a CD earns is subject to federal income tax, and in most cases state income tax as well. The bank or credit union that holds your CD will send you a Form 1099-INT each January showing how much interest you earned during the previous year. You report that amount on your tax return, and it counts as ordinary income — taxed at your regular income tax rate, not at the lower capital gains rate.

The tax is owed in the year the interest is credited to your account, even if you do not withdraw the money. If your CD automatically renews and the interest compounds, you still owe tax on the new interest each year, whether or not you touch the account.

The one exception is a CD held in a tax-advantaged account like a traditional IRA or Roth IRA. In those cases, the interest grows tax-free or tax-deferred, depending on the account type. But a regular CD in a standard savings or checking account at a bank generates a tax bill every year.

Key Takeaways

  • CD interest is taxed as ordinary income at your federal tax rate, and you owe tax in the year the interest is earned, not when you withdraw it.
  • Your bank or credit union sends Form 1099-INT in January, which reports the total interest earned and must be included on your tax return.
  • If you withdraw money before the CD matures, you may owe an early withdrawal penalty, which is separate from the income tax on the interest.
  • CDs held inside IRAs or other retirement accounts are not taxed annually because those accounts have their own tax rules.
  • State income tax on CD interest varies by state; some states do not tax interest income, while others tax it at the same rate as federal income.

How the IRS treats CD interest at tax time

When you file your federal tax return, CD interest goes on Schedule B (Interest and Ordinary Dividends) if your total interest income is more than $1,500 for the year. If it is $1,500 or less, you can report it directly on Form 1040 without using Schedule B. Either way, the interest is added to your other income and taxed at your marginal tax rate — the rate that applies to your highest dollar of income.

The amount you report must match the Form 1099-INT your bank sends to the IRS. If you do not receive a 1099-INT or if the amount is wrong, contact your bank to request a corrected form. The IRS matches 1099s filed by banks against the income you report, so discrepancies can trigger a notice.

You cannot deduct CD interest as a loss or expense. Once it is earned, it is taxable income. The only way to reduce the tax is to hold the CD in a retirement account or to earn so little interest that it falls below the reporting threshold (though you still owe tax on it even if you do not have to report it).

State income tax on CD interest

Most states that have an income tax also tax CD interest. The rate varies widely — some states tax it at the same rate as federal income, while others explore a different rate or offer a small exemption for interest income. A handful of states, including Florida, Texas, and Wyoming, do not have a state income tax at all, so residents of those states owe only federal tax on CD interest.

If you live in a state with income tax, you will typically report CD interest on your state tax return in addition to your federal return. Some states have their own version of Schedule B or a similar form. Check your state's tax authority website or your tax software to see how to report it in your state.

If you moved during the year or worked in a state different from where you live, the rules become more complex. Some states tax based on where you earned the income, others on where you live. A tax professional can help sort this out if your situation is complicated.

What happens if you withdraw a CD early

An early withdrawal from a CD usually triggers a penalty, which is separate from the income tax you owe on the interest. The penalty amount depends on the CD's term and the bank's rules — it might be a flat fee, a certain number of months of interest, or a percentage of the principal. This penalty is not tax-deductible, and you still owe income tax on all the interest you earned, even if the penalty reduces your net proceeds.

The bank will report the interest earned on Form 1099-INT, and you report that full amount as income. The penalty does not offset the taxable interest. For example, if a CD earned $500 in interest but you paid a $100 early withdrawal penalty, you still report $500 as taxable income — the penalty is straightforward money you lost.

If you are considering withdrawing early, calculate both the penalty and the tax impact before you decide. Sometimes the cost of breaking the CD is higher than you expect once you factor in the tax bill.

CDs in retirement accounts and tax-deferred growth

A CD held inside a traditional IRA grows without generating an annual tax bill. You do not receive a 1099-INT for interest earned in an IRA, and you do not report it on your tax return each year. Instead, the entire balance — principal plus all accumulated interest — is taxed as ordinary income when you withdraw it in retirement.

A CD in a Roth IRA grows tax-free. Once you reach age 59½ and have held the Roth for at least five years, you can withdraw both the principal and all the interest without owing any tax. If you withdraw before meeting those conditions, the interest portion may be taxed and subject to a penalty, depending on your age and the reason for the withdrawal.

If you have a CD in a workplace retirement plan like a 401(k), the same tax-deferral rules explore. The interest is not taxed annually, but withdrawals in retirement are taxed as ordinary income. These accounts are a tax-efficient way to hold CDs if you do not need the money in the short term.

Reporting CD interest if you did not receive a 1099-INT

Banks are required to send Form 1099-INT if the interest earned is $10 or more for the year. If you earned less than $10, the bank may not send a form, but you still owe tax on the interest. You can find the exact amount by logging into your online banking account or calling the bank.

If you earned $10 or more and did not receive a 1099-INT by late January, contact your bank. They may have the wrong address on file or may have sent it to an old address. Request a corrected form or a duplicate. Do not file your tax return without it — the IRS will have a copy, and a mismatch can delay your refund or trigger an audit notice.

If the 1099-INT shows an incorrect amount, ask the bank to issue a corrected Form 1099-INT (marked as a correction). You will then report the corrected amount on your tax return. Keep copies of all correspondence with the bank in case the IRS questions the discrepancy.

How CD interest affects your overall tax situation

CD interest is added to your adjusted gross income (AGI), which can affect other parts of your tax return. A higher AGI can reduce tax deductions you are otherwise may have access to to, phase out tax credits, or push you into a higher tax bracket. For example, if you are close to the income limit for the Earned Income Tax Credit or the Child Tax Credit, CD interest might reduce or eliminate those credits.

Similarly, if you are receiving Social Security benefits, CD interest counts toward the income threshold that determines how much of your benefits are taxable. If you are subject to the Net Investment Income Tax (a 3.8% tax on certain investment income for high-income earners), CD interest may be included in that calculation.

These interactions are complex and depend on your full financial picture. If you earn significant CD interest and receive other income or benefits, consider consulting a tax professional to understand the full impact on your return.

Frequently Asked Questions

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

Yes. Tax is owed in the year the interest is credited to your account, regardless of whether you withdraw it. If your CD automatically renews and compounds, you owe tax on the new interest each year, even if you leave all the money in the account.

What if my CD interest is less than $10?

You still owe tax on it, but the bank is not required to send a Form 1099-INT. You can find the exact amount in your account statements or online banking portal and report it on your tax return. The IRS does not have a record of it unless the bank reported it, so the burden is on you to report it accurately.

Can I deduct CD interest as an investment loss?

No. CD interest is taxable income and cannot be deducted. The only way to reduce the tax is to hold the CD in a tax-advantaged account like an IRA, where the interest grows tax-deferred or tax-free.

Does the early withdrawal penalty reduce my taxable income?

No. The penalty is not tax-deductible. You report the full interest earned as income on your tax return, and the penalty is straightforward a cost you incur. They are separate items on your tax return.

What if I moved to a different state during the year?

You may owe state income tax to both your old state and your new state, depending on each state's rules. Some states tax based on where you lived on the last day of the year, others on where you earned the income. Check both states' tax authority websites or consult a tax professional if you moved mid-year.
