A Roth account lets you save money that grows tax-free, then withdraw it tax-free in retirement

A Roth account is a retirement savings container where you contribute money that has already been taxed. The money then grows inside the account without being taxed each year, and when you withdraw it in retirement, you pay no tax on those withdrawals — not on your original contributions and not on the growth. This is the opposite of a traditional IRA or 401(k), where contributions may be tax-deductible now but withdrawals are taxed later.

The trade-off is simple: you pay tax on the money going in, but the government never taxes it again. This works best if you expect to be in a higher tax bracket in retirement, or if you simply want certainty about your tax bill decades from now.

Key Takeaways

  • You contribute after-tax dollars to a Roth account, meaning you do not get a tax deduction in the year you contribute.
  • Money inside a Roth account grows without being taxed each year, and you can withdraw both contributions and growth tax-free at retirement age.
  • Roth accounts have income limits that determine whether you can contribute directly; high earners must use a backdoor Roth or other workaround.
  • You can withdraw your own contributions (not the growth) at any time without penalty, but growth withdrawn before age 59½ usually triggers a 10 percent penalty plus income tax.
  • There is no required minimum distribution from a Roth IRA during your lifetime, so the account can keep growing as long as you live.

How contributions work: you pay tax now, not later

When you put money into a Roth account, you use money you have already paid income tax on. If you earn $50,000 and contribute $7,000 to a Roth IRA, you do not get to deduct that $7,000 from your taxable income. You still owe tax on the full $50,000. The $7,000 goes into the Roth account as after-tax money.

This is why Roth accounts are most useful if you are in a lower tax bracket now than you expect to be in retirement, or if you want to lock in current tax rates before rates potentially rise. You are essentially prepaying your taxes at today's rate in exchange for tax-free growth and withdrawals later.

How growth works: no annual tax bill inside the account

Once money is in a Roth account, it can be invested in stocks, bonds, mutual funds, or other securities. As those investments grow, you do not owe tax on the gains each year. If you buy a stock for $1,000 and it grows to $5,000, that $4,000 gain sits inside the account untaxed. If you sell that stock and buy a different one, there is no capital gains tax triggered inside the account.

This tax-free compounding is the engine of Roth accounts. Over decades, the difference between paying tax on gains each year and letting them compound untaxed can be substantial. A traditional account that is taxed annually on dividends and capital gains will have less money left to reinvest.

Withdrawal rules: contributions versus growth

The IRS treats contributions and growth differently. You can withdraw your own contributions at any time, at any age, with no penalty and no tax. If you contributed $50,000 over the years and your account is now worth $80,000, you can withdraw the $50,000 anytime without consequence.

Growth — the $30,000 in this example — is subject to restrictions. If you withdraw growth before age 59½, you owe income tax on it plus a 10 percent early withdrawal penalty. There are narrow exceptions: you can withdraw growth penalty-free (though still taxed) if you are disabled, if you use it for a first-time home purchase up to $10,000 lifetime, or if you have a may have access to medical expense. After age 59½, you can withdraw growth tax-free as long as the account has been open for at least five tax years.

The five-year rule applies to each Roth account separately. If you open a Roth IRA at age 58 and fund it heavily, you cannot withdraw the growth tax-free until age 63, even though you are past 59½. The clock starts over with each new Roth account you open.

Income limits and who can contribute directly

The IRS limits who can contribute to a Roth IRA based on your modified adjusted gross income (MAGI). These limits change each year. For 2024, if you are single, the ability to contribute phases out between roughly $146,000 and $161,000 of MAGI. If you are married filing jointly, the phase-out range is roughly $230,000 to $240,000. If your income exceeds these ranges, you cannot contribute directly to a Roth IRA.

Roth 401(k)s, offered by some employers, do not have income limits. Anyone can contribute to a Roth 401(k) regardless of how much they earn, as long as their employer offers the plan. This is why high earners often use a Roth 401(k) at work or a backdoor Roth IRA strategy to get money into a Roth account.

Roth 401(k) versus Roth IRA: the key differences

A Roth 401(k) is offered through your employer and works like a Roth IRA in terms of tax treatment — contributions are after-tax, growth is tax-free, and withdrawals are tax-free. But a Roth 401(k) has much higher contribution limits (you can contribute up to $23,500 in 2024, versus $7,000 for a Roth IRA), and it requires you to take required minimum distributions starting at age 73, whereas a Roth IRA does not.

A Roth IRA is opened on your own, has lower contribution limits, but offers more flexibility. You can withdraw contributions anytime, there are no required minimum distributions during your lifetime, and you have more control over how the money is invested. A Roth IRA also allows you to name a beneficiary who inherits the account tax-free.

Why the five-year rule matters for early withdrawals

The five-year rule is often misunderstood. It does not mean you have to wait five years to withdraw contributions — you can do that anytime. It means you have to wait five years from the year you first funded any Roth IRA to withdraw growth tax-free, even if you are over 59½.

If you open a Roth IRA in January 2024 and contribute $7,000, the five-year clock starts in 2024. In 2029, you can withdraw growth tax-free if you are 59½ or older. If you open a second Roth IRA in 2025, the five-year clock for that account also starts in 2025, and you cannot withdraw its growth tax-free until 2030. The rule applies per account, not per person.

No required minimum distributions: a major advantage

Unlike a traditional IRA or 401(k), a Roth IRA does not require you to take withdrawals at any age. You can let the money sit and grow for your entire life, then leave it to your heirs. This makes a Roth IRA a powerful tool for leaving money to the next generation, since beneficiaries inherit the account tax-free and can withdraw it over time without owing income tax on the growth.

A Roth 401(k) does require minimum distributions starting at age 73, so if you have a Roth 401(k) and want to avoid withdrawals, you may need to roll it into a Roth IRA at retirement (if your plan allows it) to eliminate the distribution requirement.

Frequently Asked Questions

Can I withdraw my contributions from a Roth IRA anytime?

Yes. You can withdraw the money you contributed (not the growth) at any age without penalty or tax. The IRS distinguishes between contributions and earnings, and contributions are always accessible. This makes a Roth IRA useful as an emergency fund if needed, though it is designed for retirement.

What happens if I withdraw growth before age 59½?

You owe income tax on the growth plus a 10 percent early withdrawal penalty, unless an exception applies. Exceptions include disability, first-time home purchase (up to $10,000 lifetime), or may have access to medical expenses. After age 59½, you can withdraw growth tax-free as long as the account has been open for five tax years.

Do I have to take money out of my Roth IRA when I turn 73?

No. A Roth IRA has no required minimum distributions during your lifetime. You can leave the money untouched and let it grow. A Roth 401(k) does require distributions starting at age 73, but you can roll it into a Roth IRA to avoid that requirement.

What is a backdoor Roth and why would I use one?

A backdoor Roth is a strategy for high earners to fund a Roth IRA when their income exceeds the direct contribution limits. You contribute to a traditional IRA (which has no income limit), then convert it to a Roth IRA. This works if you have no other traditional IRA balances; if you do, the pro-rata rule may create a tax bill. Consult a tax professional before attempting a backdoor Roth.

Can I have both a Roth IRA and a traditional IRA?

Yes, but your total contributions to both accounts combined cannot exceed the annual limit ($7,000 in 2024 for most people). If you contribute $4,000 to a traditional IRA, you can only contribute $3,000 to a Roth IRA that year. The limits are per person, not per account type.
