A Roth account lets you put money in after taxes, 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 trade-off is that when you withdraw that money in retirement—along with all the growth it earned—you pay no federal income tax on any of it. The IRS lets you open a Roth if you have earned income, but there are income limits that phase out your ability to contribute once you earn above a certain threshold.

The most common Roth account is a Roth IRA, which is an individual retirement account you open at a bank, brokerage, or credit union. A Roth 401(k) is the workplace version, offered by some employers. Both follow the same basic rule: you pay taxes now, the account grows tax-free, and withdrawals in retirement are tax-free.

Key Takeaways

  • You contribute after-tax dollars to a Roth account, meaning you do not get a tax deduction in the year you contribute.
  • All growth inside the account—dividends, capital gains, interest—is never taxed as long as the money stays in the account.
  • Withdrawals in retirement are completely tax-free, including the growth, as long as you follow the rules.
  • Roth IRAs have income limits; if you earn too much, you cannot contribute directly, though a backdoor Roth workaround exists.
  • You can withdraw your contributions (not the growth) at any time without penalty, but growth withdrawals before age 59½ usually trigger a 10% penalty plus taxes.

How contributions work and who can open one

To open a Roth IRA, you need earned income—wages from a job, self-employment income, or taxable alimony. You cannot fund a Roth with investment returns, Social Security, or pension payments. You can open one at nearly any bank or brokerage; there is no employer involved unless you are using a workplace Roth 401(k).

For 2024, you can contribute up to $7,000 per year to a Roth IRA if you are under 50, or $8,000 if you are 50 or older. Those limits change yearly. However, if your income exceeds certain thresholds, your ability to contribute phases out. For 2024, a single filer begins to lose the ability to contribute at $146,000 in modified adjusted gross income; a married couple filing jointly phases out between $230,000 and $240,000. These numbers shift each year.

If your income is above the limit, you cannot contribute directly to a Roth IRA. Some people use a backdoor Roth strategy—contributing to a traditional IRA and then converting it to a Roth—but this involves tax complications and requires careful record-keeping.

The tax advantage: growth and withdrawals

The core benefit of a Roth is that money grows tax-free inside the account. If you invest $7,000 and it grows to $50,000 over 30 years, you never pay tax on that $43,000 in gains. Compare that to a taxable brokerage account, where you would owe tax each year on dividends and capital gains, and again when you sell.

In retirement, you can withdraw everything—your original contributions plus all the growth—without owing federal income tax. This is different from a traditional IRA or 401(k), where withdrawals are taxed as ordinary income because you got a tax deduction when you contributed.

The tax-free withdrawal rule has one condition: the account must be at least five years old, and you must be at least 59½ years old. If you withdraw before meeting both conditions, the growth portion is taxed as income plus hit with a 10% early withdrawal penalty. Your contributions can always come out penalty-free, but the growth cannot.

Roth IRA vs. Roth 401(k): which one you might have

A Roth IRA is opened by you as an individual. You choose where to open it, what to invest in, and how much to contribute (up to the annual limit). There are no required withdrawals during your lifetime—you can leave the money untouched as long as you want.

A Roth 401(k) is offered by your employer. Your contributions come out of your paycheck after taxes. Your employer may match your contributions, and that match goes into a traditional (pre-tax) portion of the account. Roth 401(k)s have much higher contribution limits—$23,500 per year in 2024 if you are under 50—but they require you to start taking withdrawals at age 73, even if you do not need the money.

If your employer offers a Roth 401(k), you can still open and fund a Roth IRA at the same time, as long as your income is below the phase-out limit. Many people do both.

When to withdraw money and what happens if you break the rules

Your contributions to a Roth IRA can be withdrawn at any time, for any reason, with no tax or penalty. This is a safety valve: if you need money, you can pull out what you put in. The growth, however, is locked until you are 59½ and the account is five years old.

If you withdraw growth before age 59½, the IRS taxes it as ordinary income and adds a 10% penalty. There are a few exceptions: you can withdraw growth penalty-free (but not tax-free) if you are a first-time homebuyer buying your first home (up to $10,000 lifetime), if you become disabled, or if you die and your beneficiary is withdrawing. Withdrawals for education expenses or medical bills do not may have access to for the exception.

Once you reach 59½ and the account has been open for five years, all withdrawals are tax-free and penalty-free. You can withdraw as much or as little as you want, whenever you want. Unlike a traditional IRA or 401(k), there is no required minimum distribution during your lifetime.

Income limits and what to do if you earn too much

The IRS phases out Roth contributions based on your modified adjusted gross income (MAGI). For 2024, single filers lose the ability to contribute between $146,000 and $161,000; married couples filing jointly phase out between $230,000 and $240,000. If you are above the upper limit, you cannot contribute directly.

If you are above the limit but want to fund a Roth, the backdoor Roth is the standard workaround. You contribute to a traditional IRA (which has no income limit), then immediately convert it to a Roth. You pay tax on any pre-tax IRA balances you already have, but the conversion itself is legal. This strategy requires careful tax planning and is not right for everyone, especially if you have existing traditional IRA balances.

Another option is a Roth 401(k) if your employer offers one. Roth 401(k)s have no income limits, so high earners can use them to save in a Roth structure.

Roth accounts vs. traditional retirement accounts

The choice between a Roth and a traditional account comes down to whether you think your tax rate will be higher now or in retirement. If you expect to be in a lower tax bracket in retirement, a traditional account (where you deduct contributions now) makes sense. If you expect to be in the same or higher bracket, a Roth (where you pay tax now at today's rate) is usually better.

A Roth also offers flexibility: you can withdraw contributions anytime, there are no required withdrawals during your lifetime, and tax-free growth compounds over decades. A traditional account forces you to take withdrawals starting at age 73, which can push you into a higher tax bracket and affect other benefits like Medicare premiums.

Many people use both: a traditional 401(k) at work (especially if the employer matches) and a Roth IRA for additional savings. This gives you a mix of pre-tax and after-tax money in retirement, letting you manage your tax bill year to year.

Frequently Asked Questions

Can I have both a Roth IRA and a traditional IRA at the same time?

Yes, but your total contributions to both accounts in a single year cannot exceed the annual limit—$7,000 for 2024 if you are under 50. If you contribute $4,000 to a traditional IRA, you can only contribute $3,000 to a Roth that year. The limit applies across all IRAs you own.

What happens to my Roth IRA if I die?

Your beneficiary inherits the account and can withdraw the money tax-free. If they are your spouse, they can treat it as their own Roth. Non-spouse beneficiaries must withdraw the balance within 10 years under current rules, though the withdrawals themselves are tax-free.

Can I move money from a traditional IRA to a Roth?

Yes, through a conversion. You pay income tax on the amount converted in that tax year, but once it is in the Roth, all future growth is tax-free. Conversions are useful if you expect your tax rate to be lower in the conversion year than in retirement, or if you want to reduce future required withdrawals.

Do I pay taxes on Roth contributions when I file my return?

No. Roth contributions are made with after-tax money, so you do not report them on your tax return. You do not get a deduction, and you do not owe tax on them. The IRS only cares about Roth withdrawals in retirement.

What if I need money before age 59½?

You can withdraw your contributions anytime penalty-free. If you need the growth, you can withdraw it, but it will be taxed as ordinary income plus hit with a 10% penalty unless you may have access to for an exception like disability or a first-time home purchase.
