How savings, money market and CD interest is taxed

Interest from a high-yield savings account, money market account or CD is taxable income in the year it is credited to you, whether you withdraw it or not. Here is how it shows up on your return and the details that trip people up.

General information, not tax advice. This guide explains how federal and state rules generally work. Your situation may differ; check the official source linked below or ask a tax professional before acting.

The short version

It is ordinary income. Interest is taxed at your regular federal bracket, plus state income tax in most states.
It counts when it is credited, not when you withdraw it. Interest that compounds inside the account is still income for that year.
Banks send Form 1099-INT by January 31 when they paid you at least $10 of interest. Smaller amounts are still taxable.
Multi-year CDs can create tax before maturity because interest is generally reported as it accrues each year.
Early-withdrawal penalties are deductible as an adjustment to income.

Form 1099-INT: what each box means for savers

Box	What it shows	Where it goes
1	Interest income from savings, money market, checking and CDs (including bank sign-up bonuses that the bank treats as interest)	Form 1040 taxable interest; Schedule B if your total taxable interest is over $1,500
2	Early withdrawal penalty charged for breaking a CD or other time deposit	Schedule 1 adjustment to income
3	Interest on U.S. savings bonds and Treasury obligations	Federally taxable; exempt from state and local income tax
4	Federal income tax withheld (backup withholding)	Payments section of your return
8	Tax-exempt interest (for example, municipal bonds)	Reported, but not federally taxed

Box descriptions follow the IRS instructions for Forms 1099-INT and 1099-OID. Brokerage accounts usually combine these figures in a consolidated 1099.

When interest becomes taxable

Interest is taxed in the year it is credited to your account and available to withdraw (the IRS calls this constructive receipt). A savings account that compounds daily and credits interest monthly creates twelve small pieces of income during the year, and your 1099-INT adds them up. Leaving the money in the account does not delay the tax.

Interest that a bank has not yet credited at year-end, for example interest for the last days of December that posts in January, generally belongs to the next tax year.

CDs: short terms vs multi-year terms

CDs of one year or less. Interest is generally taxable in the year it is paid or credited. A 6-month CD opened in October and maturing in April is usually taxed in the year it matures, unless the bank credits interest to the account earlier (for example monthly), in which case each credit counts when it posts.

CDs longer than one year. Interest on these is generally treated as accruing each year, even when the bank pays it only at maturity. The bank reports the accrued amount every year, often on Form 1099-INT, or on Form 1099-OID when the CD pays everything at maturity. On a 5-year CD you can therefore owe tax on interest every year for five years before you see the money. Plan for that tax from other savings, or choose a CD that pays interest out periodically.

Brokered CDs held at a brokerage are reported on the brokerage's consolidated 1099. If you sell one before maturity, a gain or loss on the sale is reported separately from the interest.

Breaking a CD early: the penalty deduction

If you cash out a CD before it matures, the bank keeps a penalty, usually a number of months of interest. You still report all the interest the CD earned in box 1, and you deduct the penalty from box 2 as an adjustment to income on Schedule 1. Because it is an adjustment, you get it whether or not you itemize. If the penalty is larger than the interest you earned, the deduction can exceed the interest.

State tax on interest

Most states with an income tax tax bank and credit union interest the same way the IRS does. Nine states have no income tax on interest. Interest from U.S. Treasury bills, notes, bonds and savings bonds is exempt from state and local income tax under federal law, which can make Treasuries pay more after tax than a CD with a slightly higher rate. Our guide to the state tax exemption on Treasury interest has a table for every state.

Accounts where interest is not taxed yet

Interest earned inside a traditional or Roth IRA (including IRA CDs), a health savings account or a 529 plan is not reported each year. It is taxed, or not, under that account's rules when you withdraw.

Other details

Joint accounts. The 1099-INT goes to the person whose Social Security number is on the account. If part of the interest belongs to someone else, IRS Publication 550 explains how to report it as a nominee.
Net Investment Income Tax. Interest counts toward the 3.8% tax on investment income above $200,000 of modified AGI (single) or $250,000 (married filing jointly). These thresholds are not adjusted for inflation.
Estimated tax. Banks do not withhold tax on interest unless backup withholding applies. Large interest income can mean you need to pay estimated tax or raise your paycheck withholding. See our tax deadlines for the 2027 estimated-payment dates.

Frequently asked questions

Do I have to report interest if I did not get a 1099-INT?

Yes. Banks generally send Form 1099-INT only when they paid you $10 or more of interest, but all taxable interest is reportable, including smaller amounts and interest from accounts that did not send a form.

Is savings account interest taxed as ordinary income?

Yes. Interest from savings, money market and checking accounts and from CDs is taxed at your ordinary federal income tax rate, not at the lower long-term capital gains rate.

When is CD interest taxed if I do not get it until the CD matures?

For a CD with a term of one year or less, interest is generally taxed in the year it is paid or credited and available to you. For a CD longer than one year, the bank usually reports interest each year as it accrues (often on Form 1099-INT or Form 1099-OID), so you can owe tax on interest before the CD matures.

Can I deduct a CD early-withdrawal penalty?

Yes. A penalty for withdrawing a time deposit early is shown in box 2 of Form 1099-INT (or 1099-OID) and is deducted as an adjustment to income on Schedule 1, even if you take the standard deduction. You still report the full interest in box 1.

Is bank interest taxed by my state?

In most states, yes. States with an income tax generally tax bank and credit union interest. Nine states have no income tax on interest. Interest on U.S. Treasury securities and savings bonds is exempt from state and local income tax everywhere.

Does interest count toward the Net Investment Income Tax?

Yes. Taxable interest is net investment income, so it can be subject to the 3.8% Net Investment Income Tax if your modified adjusted gross income is above $200,000 (single) or $250,000 (married filing jointly).
