Roth IRA contributions and earnings are taxed differently — and that difference is the whole point

Money you put into a Roth IRA is not tax-deductible, and you do not pay taxes when you withdraw it later. Earnings inside the account — the interest, dividends, and investment gains — are also tax-free when you withdraw them, but only if you follow the withdrawal rules. The tradeoff is that you fund a Roth with after-tax dollars instead of getting a tax break upfront like you do with a traditional IRA.

The tax treatment depends on what you are withdrawing and how long the money has been in the account. Contributions always come out tax-free. Earnings come out tax-free only if the account has been open for at least five years and you are at least 59½ years old, or if you meet one of a few other exceptions.

Key Takeaways

  • Contributions to a Roth IRA are made with after-tax money and can be withdrawn at any time without taxes or penalties.
  • Earnings inside a Roth IRA grow tax-free and can be withdrawn tax-free if the account is at least five years old and you are at least 59½.
  • If you withdraw earnings before meeting the age and five-year rules, you owe income tax on those earnings plus a 10 percent early withdrawal penalty.
  • Roth IRAs have no required minimum distributions during your lifetime, so the tax-free growth can continue as long as you leave the money alone.

How contributions are taxed

You fund a Roth IRA with money you have already paid income tax on. That means the IRS has already taken its cut, and you get no deduction on your tax return for putting money in. The contribution itself is never taxed again.

You can withdraw your contributions at any time, for any reason, without owing taxes or facing a penalty. The IRS considers this your own money coming back to you. This is different from a traditional IRA, where contributions may be tax-deductible and withdrawals are taxed as income.

The catch is that you can only withdraw contributions, not earnings, without a penalty before age 59½. If you mix the two, the IRS uses a formula called the pro-rata rule to figure out how much of your withdrawal is contributions (tax-free) and how much is earnings (taxable).

How earnings are taxed

Interest, dividends, and capital gains that build up inside your Roth IRA are not taxed each year the way they would be in a regular brokerage account. The money compounds tax-free. You do not file a form or pay anything annually.

When you withdraw earnings, the tax treatment depends on your age and how long the account has been open. If you are 59½ or older and the account has been open for at least five years, the earnings come out tax-free. If either condition is not met, you owe income tax on the earnings plus a 10 percent early withdrawal penalty.

The five-year rule is tied to the account itself, not to each contribution. Once you open a Roth IRA, the clock starts. If you open a second Roth IRA later, each account has its own five-year clock, but most people treat all their Roth IRAs as one for this purpose under IRS rules.

Early withdrawal penalties and exceptions

If you withdraw earnings before age 59½ and the account is less than five years old, you owe a 10 percent penalty on top of income tax. This penalty applies to the earnings only, not to your contributions.

A few situations let you withdraw earnings without the 10 percent penalty, though you may still owe income tax. These include a first-time home purchase (up to $10,000 lifetime), disability, medical expenses over 7.5 percent of your adjusted gross income, and health insurance premiums while unemployed. You still need the account to be five years old to avoid the income tax itself.

If you inherit a Roth IRA from a spouse, you can treat it as your own and follow the normal rules. If you inherit one from someone else, the rules are stricter and depend on when the original owner opened the account.

Roth conversions and their tax cost

If you move money from a traditional IRA or 401(k) into a Roth IRA, that conversion is a taxable event. You owe income tax on the amount you convert in the year you do it, as if you had withdrawn the money. You do not owe a penalty, but you do owe the tax.

Once the money is in the Roth, it follows the normal Roth rules: contributions are tax-free to withdraw, and earnings are tax-free if the account is five years old and you are 59½. Many people convert small amounts over several years to spread out the tax bill, or they convert in years when their income is lower.

No required withdrawals during your lifetime

Traditional IRAs force you to start taking withdrawals at age 73 (as of 2023), and those withdrawals are taxed as income. Roth IRAs have no required minimum distributions while you are alive. You can leave the money alone to grow tax-free for as long as you want.

This makes a Roth useful if you do not need the money in retirement and want to leave it to heirs. The tax-free growth continues, and your beneficiaries inherit the account with the same tax-free withdrawal rules — though they do have to take distributions over time under current law.

Income limits and backdoor Roth strategies

You can only contribute directly to a Roth IRA if your income is below a certain threshold, which changes each year. If your income is too high, you cannot contribute directly, but you can use a backdoor Roth strategy: contribute to a traditional IRA (which has no income limit) and then convert it to a Roth.

The backdoor conversion itself is taxable in the year you do it, but it lets higher earners get money into a Roth when they otherwise could not. If you have other traditional IRA money, the pro-rata rule may create a tax bill on part of the conversion.

Frequently Asked Questions

Do I have to pay taxes on Roth IRA growth every year?

No. The money inside a Roth IRA grows tax-free, and you do not file any forms or pay taxes annually on the interest, dividends, or gains. You only pay taxes when you withdraw earnings, and only if you do not meet the age and five-year rules.

Can I withdraw my contributions without paying taxes?

Yes. Your contributions to a Roth IRA can be withdrawn at any time, tax-free and penalty-free, because you already paid tax on that money when you earned it. Only earnings are subject to the five-year and age 59½ rules.

What happens if I withdraw earnings before age 59½?

You owe income tax on the earnings plus a 10 percent early withdrawal penalty, unless the account is at least five years old or you meet an exception like a first-time home purchase or disability. Contributions can still be withdrawn penalty-free.

Is a Roth IRA conversion taxable?

Yes. When you convert money from a traditional IRA or 401(k) to a Roth, you owe income tax on the amount converted in that tax year. After the conversion, the money follows normal Roth rules and grows tax-free.

Do I have to take money out of my Roth IRA in retirement?

No. Unlike traditional IRAs, Roth IRAs have no required minimum distributions during your lifetime. You can leave the money alone to grow tax-free for as long as you want, making a Roth useful for leaving money to heirs.
