The short answer: contributions and growth are not taxed, withdrawals in retirement are tax-free

A Roth IRA is taxed differently than a traditional IRA or 401(k). You put money in after you have already paid income tax on it. The money grows inside the account without triggering taxes each year. When you withdraw in retirement, you owe nothing — not on the growth, not on the original contributions, nothing.

The trade-off is that you do not get a tax deduction when you contribute. You pay tax on the money before it goes in. But once it is in, the IRS leaves it alone.

Key Takeaways

  • Contributions to a Roth IRA come from money you have already paid income tax on, so you get no deduction in the year you contribute.
  • Investment earnings inside the account — interest, dividends, capital gains — are not taxed while the money sits there.
  • Withdrawals of contributions and earnings after age 59½ and after the account has been open five years are completely tax-free.
  • Early withdrawals of earnings before age 59½ are subject to income tax and usually a 10 percent penalty, though contributions can come out anytime without penalty.
  • Your income level determines whether you can contribute to a Roth IRA at all, but income does not affect how the account is taxed once it is open.

Why you pay tax going in, not coming out

The Roth IRA was created to let people pay their taxes upfront and then never pay them again on that money. You contribute with after-tax dollars — money you have already reported as income and paid tax on. The IRS knows you already paid, so it does not tax the contribution itself.

The benefit comes later. A traditional IRA or 401(k) lets you deduct contributions from your income in the year you make them, which lowers your tax bill that year. But then you pay tax on everything you withdraw in retirement. A Roth IRA flips this: no deduction now, no tax later.

This matters most if you expect to be in a higher tax bracket in retirement than you are now, or if you simply want to lock in your current tax rate and avoid uncertainty about future rates.

How investment growth is treated

Money inside a Roth IRA can earn interest, dividends, or capital gains. If you own stocks that double in value, or bonds that pay interest, or mutual funds that distribute gains, none of that triggers a tax bill in the year it happens. This is called tax-deferred growth.

In a regular taxable brokerage account, you would owe tax on dividends and capital gains each year, even if you did not sell anything. In a Roth IRA, the earnings compound without any annual tax drag. Over decades, this can make a significant difference in how much money accumulates.

The catch is that this tax-free growth only applies if you follow the withdrawal rules. If you take money out early, the earnings portion may be taxed and penalized.

Withdrawals after 59½ and the five-year rule

Once you reach age 59½ and your Roth IRA has been open for at least five years, you can withdraw both your contributions and all the earnings completely tax-free. This is the main payoff of the Roth structure.

The five-year rule is per account, not per person. If you open a Roth IRA at age 58, you cannot take tax-free withdrawals of earnings until age 63 (five years later), even if you have other Roth IRAs that are older. Contributions, however, can always come out without penalty or tax.

The five-year clock also resets if you convert a traditional IRA to a Roth IRA. That conversion counts as a new Roth account for the five-year rule, even though you may have had other Roth IRAs for years.

Early withdrawals and the 10 percent penalty

If you withdraw earnings before age 59½, you owe income tax on those earnings plus a 10 percent penalty. Contributions can come out anytime without penalty or tax, because you already paid tax on them.

There are a few exceptions to the penalty. You can withdraw earnings without penalty if you use the money for a first home purchase (up to $10,000 lifetime), if you are disabled, if you are a beneficiary withdrawing after the account holder's death, or if you use the money for may have access to education expenses. Taxes still apply in most of these cases, but the penalty is waived.

The distinction between contributions and earnings matters. If you contributed $5,000 and it grew to $7,000, you can pull out the $5,000 anytime with no tax or penalty. Pulling out the $7,000 before 59½ triggers tax and penalty on the $2,000 in earnings.

Required Minimum Distributions do not apply during your lifetime

A traditional IRA forces you to start taking money out at age 73 (as of 2023), whether you need it or not. These Required Minimum Distributions, or RMDs, are taxable and can push you into a higher tax bracket.

A Roth IRA has no RMD requirement while you are alive. You can leave the money untouched for as long as you want, and it keeps growing tax-free. This makes a Roth IRA a powerful tool for leaving money to heirs, since they inherit an account with decades of tax-free growth already built in.

Beneficiaries who inherit a Roth IRA do have to take distributions, but those distributions are still tax-free (as long as the five-year rule was met). The tax-free status carries forward to the next generation.

Income limits affect who can contribute, not how the account is taxed

Your income determines whether you can contribute to a Roth IRA in the first place. If your income is above a certain threshold, you cannot contribute directly. These thresholds change each year and depend on your filing status.

But income limits do not affect how the account is taxed once it is open. If you were able to open a Roth IRA years ago when your income was lower, and your income has since risen, the account still grows tax-free and withdrawals are still tax-free. The income limit only gates entry; it does not change the tax treatment of money already inside.

Some people use a backdoor Roth strategy to get around income limits. They contribute to a traditional IRA and then convert it to a Roth IRA. The conversion itself may trigger taxes, but once the money is in the Roth, it follows the same tax-free rules.

Frequently Asked Questions

Do I have to pay taxes on Roth IRA dividends and interest?

No. Dividends, interest, and capital gains inside a Roth IRA are not taxed while the money is in the account. You only pay tax on these earnings if you withdraw them before age 59½ and before the five-year holding period is met.

What happens if I withdraw money before age 59½?

Contributions come out tax-free and penalty-free anytime. Earnings are subject to income tax plus a 10 percent penalty, unless an exception applies (first home, disability, education, death). You can find out which portion is contributions and which is earnings by checking your account statements or asking your provider.

Can I avoid taxes by converting a traditional IRA to a Roth?

No. When you convert, you owe income tax on the amount converted in that tax year. However, once the money is in the Roth, future growth and withdrawals are tax-free. The conversion itself is a taxable event, but it sets up tax-free treatment going forward.

Do I have to take money out of my Roth IRA at a certain age?

No. You have no Required Minimum Distributions from a Roth IRA during your lifetime. You can leave the money untouched for as long as you want. Beneficiaries who inherit the account do have to take distributions, but those distributions remain tax-free.

Is a Roth IRA better than a traditional IRA for taxes?

It depends on your situation. A Roth is better if you expect to be in a higher tax bracket in retirement, or if you want to avoid RMDs and leave tax-assistance programs to heirs. A traditional IRA is better if you want a tax deduction now and expect to be in a lower bracket in retirement. Many people benefit from having both.
