Is IRA Interest Taxable? Traditional, Roth, and Inherited IRA Rules

Is IRA interest taxable? Not while it sits inside the account. Interest, dividends, and capital gains compound inside both traditional and Roth IRAs without any annual tax bill.¹ The tax question only matters when money comes out. Traditional IRA withdrawals, including all the interest you earned, are taxed as ordinary income at federal rates that run from 10% to 37% for 2026. Qualified Roth IRA withdrawals, interest included, are completely tax-free.²

Interest in a Traditional IRA

Inside a traditional IRA, the IRS ignores whatever the account earns from year to year. Bond interest, dividends, and gains all reinvest untaxed.¹ You owe nothing until you take a distribution.

When you do withdraw, and every dollar you contributed was tax-deductible, the entire distribution is taxable. The IRS does not separate interest from original contributions or from stock gains. It all gets added to your ordinary income for the year.³ For 2026, that means anywhere from 10% on the first $12,400 of taxable income for a single filer up to 37% on income above $640,600.²

Traditional IRAs also carry required minimum distributions starting at age 73. Each RMD is taxed as ordinary income the year you receive it.⁴ Roth IRAs have no lifetime RMDs.

When Some Contributions Were Not Deductible

Some traditional IRA contributions cannot be deducted. If you are covered by a workplace retirement plan and your income is above certain thresholds, part or all of your contribution is nondeductible. For 2026, the deduction begins phasing out for single filers at $81,000 of modified adjusted gross income and disappears at $91,000. For married couples filing jointly, the phaseout runs from $129,000 to $149,000.²

Once your account holds both deductible and nondeductible contributions, you cannot cherry-pick the after-tax portion when you withdraw. A pro-rata rule applies: each distribution contains a proportional slice of taxable and nontaxable money, based on the ratio of your total after-tax basis to your total traditional IRA balance across all your traditional IRAs.⁵ If your combined balance is $100,000 and $20,000 came from nondeductible contributions, 80% of any withdrawal is taxable.

You track after-tax basis on Form 8606, which you must file with your return for any year you take a distribution from a traditional IRA that includes nondeductible contributions.⁶ Skip the form and the IRS has no record of your basis, so the whole withdrawal may be treated as taxable.

Interest in a Roth IRA

Roth contributions go in after tax, and in exchange qualified withdrawals of both contributions and earnings come out completely tax-free.⁷ Interest compounding inside the account never triggers a tax bill along the way.

The word “qualified” carries the weight. Roth earnings are tax-free only if the distribution meets the rules below. Pull earnings out before you qualify and the growth becomes taxable income, potentially with a penalty on top.

What Makes a Roth Distribution Qualified

Two conditions have to be true at the same time.⁷

First, five tax years must have passed since January 1 of the year you first contributed to any Roth IRA. If you opened your first Roth in March 2022, the clock started January 1, 2022, and the five-year window closes at the end of 2026. Opening a second Roth later does not restart it; the clock runs once.

Second, one of these has to apply:

You are at least 59½
You are permanently disabled
The distribution goes to a beneficiary after your death
You withdraw up to $10,000 for a first-time home purchase (a lifetime cap)

Meet both conditions and the entire withdrawal, interest included, is tax-free no matter how much the account has grown.

Ordering Rules for Early Roth Withdrawals

Take money out of a Roth before you qualify and the IRS applies a fixed order to figure out what portion is earnings.⁸ Regular contributions come out first, always tax-free and penalty-free because you already paid tax on them. Conversion and rollover amounts come out next, in chronological order, with the taxable portion of each conversion ahead of the nontaxable portion. Earnings come out last, and only these are potentially taxable and subject to penalty.

That ordering is why many people can dip into a Roth early without a tax bill. As long as the amount withdrawn stays at or below total contributions, no interest is being touched.

The 10% Early Withdrawal Penalty

Take money out of any IRA before 59½ and a 10% additional tax generally applies on top of ordinary income tax.⁹ For a traditional IRA, the penalty hits the full taxable amount. For a Roth, it only reaches the earnings portion, since the ordering rules protect your contributions.

Several exceptions waive the 10%, though traditional IRA distributions remain taxable as ordinary income even when the penalty is off:⁹

Unreimbursed medical expenses above 7.5% of adjusted gross income
Health insurance premiums while unemployed, after at least 12 weeks of unemployment compensation
Higher education expenses for you, your spouse, or dependents
First-time home purchase, up to a $10,000 lifetime limit
Total and permanent disability
Birth or adoption expenses, up to $5,000 per child
Substantially equal periodic payments over your life expectancy
An IRS levy on the account
Federally declared disaster losses, up to $22,000
Domestic abuse victim distributions, up to the lesser of $10,000 or 50% of the balance, for distributions after December 31, 2023

Interest Taxed During a Roth Conversion

Converting a traditional IRA to a Roth is the one moment when accumulated interest in a traditional account gets taxed while you are still working with the money. The untaxed portion of the converted amount, including all the interest and gains that grew from deductible contributions, is added to your taxable income for the year of the conversion.¹⁰ Convert $50,000 from a fully deductible traditional IRA and $50,000 gets stacked on top of your other income at your marginal rates.

Each conversion also starts its own five-year clock for the 10% early withdrawal penalty on the converted principal. This clock is separate from the overall five-year rule for tax-free Roth earnings.

Interest From an Inherited IRA

Taxable distributions from an inherited IRA are included in your gross income for the year you receive them.¹¹ What that looks like depends on the account type and your relationship to the person who died.

A surviving spouse has the most flexibility. You can roll the inherited IRA into your own account and treat it as always yours, keep it as an inherited account with distributions based on your life expectancy, or follow the 10-year rule.¹¹

Most non-spouse beneficiaries who inherited from someone who died in 2020 or later have to empty the account within 10 years of the original owner’s death.¹¹ Every distribution from an inherited traditional IRA is ordinary income to the beneficiary. Distributions from an inherited Roth are typically tax-free, provided the original owner had already satisfied the five-year holding period.

A narrow group of eligible designated beneficiaries can stretch distributions over their own life expectancy instead: minor children of the deceased (the 10-year clock starts once they reach the age of majority), disabled or chronically ill individuals, and anyone no more than 10 years younger than the deceased owner.¹¹

How Distributions Show Up on Your Tax Return

Your IRA custodian sends Form 1099-R by January 31 after any year you take a distribution.¹² Box 1 shows the gross distribution, Box 2a shows the taxable portion, and the IRS receives the same copy, so the figures on your return must match.

Box 7 carries a code explaining what kind of distribution occurred. The ones you are most likely to see:¹²

Code 1: early distribution, no known exception. Expect the 10% penalty unless you claim an exception
Code 2: early distribution, exception applies
Code 7: normal distribution after 59½
Code Q: qualified Roth distribution, entirely tax-free
Code J: early Roth distribution, no known exception

On Form 1040, the gross distribution goes on Line 4a and the taxable amount on Line 4b.¹³ When the whole distribution is taxable, only Line 4b is filled in.

File Form 8606 alongside your return if your traditional IRA contains nondeductible contributions, if you took a nonqualified Roth distribution, or if you converted funds to a Roth during the year.⁶ This form is how the IRS learns you have basis in the account; without it, you can end up paying tax twice on the same dollars.

State Income Tax

Federal rules are only half the picture. Most states with an income tax treat traditional IRA distributions as taxable income, though the details vary: some states exempt all retirement income, others offer partial exclusions that phase out by age or income, and a handful have no income tax at all. Check your state’s current treatment before taking a large distribution.
