A Roth is a retirement account where you pay taxes now and withdraw money tax-free later
A Roth is a type of individual retirement account (IRA) created by Congress in 1997. The defining feature is the tax order: you contribute money that has already been taxed, the account grows without annual tax bills, and you withdraw it tax-free in retirement. This is the opposite of a traditional IRA, where contributions may be tax-deductible now but withdrawals are taxed as income later.
The trade-off is simple. You give up a tax deduction today in exchange for tax-free growth and withdrawals tomorrow. Whether that trade makes sense depends on whether you expect to be in a higher tax bracket in retirement than you are now — and whether you want the flexibility of tax-free withdrawals regardless of your income level.
The Roth was designed for people who expect their income or tax rates to rise, or who simply want certainty about their tax bill in retirement. It also has no required minimum distributions (RMDs), meaning you do not have to withdraw money at age 73 if you do not need it, and you can leave the account to heirs tax-free.
Key Takeaways
- You fund a Roth with after-tax dollars, so contributions do not reduce your taxable income this year.
- Money inside a Roth grows without triggering annual income tax, and you withdraw it tax-free in retirement.
- You can withdraw your contributions (not earnings) at any time without penalty, even before retirement age.
- Income limits apply: if you earn above a certain threshold, you cannot contribute directly to a Roth IRA, though a backdoor Roth conversion may be an option.
- A Roth has no required minimum distributions, so you can leave money untouched and pass it to heirs tax-free.
How contributions and growth work inside a Roth
When you put money into a Roth, you are using dollars you have already paid income tax on. For 2024, you can contribute up to $7,000 per year if you are under 50, or $8,000 if you are 50 or older. (These limits change annually.) That contribution does not reduce your taxable income on your tax return — you get no deduction.
Once the money is in the account, it can be invested in stocks, bonds, mutual funds, or other securities. Any gains — dividends, capital appreciation, interest — accumulate without triggering a tax bill each year. In a taxable brokerage account, you would owe tax on dividends and capital gains every year. In a Roth, you owe nothing until you withdraw.
The earnings stay sheltered as long as the money stays in the account. This tax-free compounding is the core benefit of a Roth, especially for younger savers who have decades for money to grow.
Withdrawal rules: contributions versus earnings
The Roth has two separate withdrawal rules, one for contributions and one for earnings. You can withdraw your contributions at any time, for any reason, with no penalty and no tax. This is a major difference from a traditional IRA, where any withdrawal before age 59½ is subject to a 10% penalty plus income tax.
Earnings are different. If you withdraw earnings before age 59½ and before the account has been open for five years, you owe income tax on the earnings plus a 10% penalty. However, if you are 59½ or older and the account has been open for at least five years, you can withdraw earnings tax-free and penalty-free.
There are a few exceptions to the early withdrawal penalty on earnings: first-time home purchase (up to $10,000 lifetime), may have access to education expenses, disability, and a few others. But the five-year rule applies to all of them.
Income limits and who can contribute
The IRS limits who can contribute directly to a Roth based on your modified adjusted gross income (MAGI). For 2024, if you file as single and earn more than $146,000, you cannot contribute the full amount. If you earn more than $161,000, you cannot contribute at all. For married filing jointly, the limits are $230,000 and $240,000.
These limits change every year, and they are different if you are married filing separately or head of household. If your income exceeds the limit, you have two options: wait for your income to drop, or use a backdoor Roth conversion, which involves contributing to a traditional IRA and then converting it to a Roth. A backdoor Roth has no income limit, but it comes with tax complications if you already have other traditional IRA balances.
Roth versus traditional IRA: the tax timing difference
The choice between a Roth and a traditional IRA comes down to tax timing. With a traditional IRA, you may deduct your contribution now (depending on income and whether you have a workplace retirement plan), which lowers your taxable income this year. But withdrawals in retirement are taxed as ordinary income.
With a Roth, you get no deduction now, but withdrawals are tax-free. If you expect to be in a lower tax bracket in retirement, a traditional IRA may save you more money overall. If you expect to be in a higher bracket, or if you simply want to lock in today's tax rate, a Roth makes sense.
A Roth also gives you more flexibility: you can withdraw contributions anytime, you have no required minimum distributions, and you can pass the account to heirs tax-free. A traditional IRA forces you to start withdrawing at age 73, and those withdrawals are taxable to your heirs.
Roth conversions and the five-year rule
If you have money in a traditional IRA or a 401(k), you can convert some or all of it to a Roth. You will owe income tax on the amount converted (unless it was already after-tax money), but once it is in the Roth, it grows tax-free.
A conversion starts a new five-year clock for the earnings in that converted amount. If you convert $50,000 from a traditional IRA to a Roth and then withdraw it within five years, you owe a 10% penalty on the earnings portion (if you are under 59½). The contributions themselves can always come out penalty-free.
Conversions are useful for people who expect their tax rate to rise, or who want to move money into a tax-free account before they reach the age when required minimum distributions kick in. They are also a way around the income limits if you cannot contribute directly to a Roth.
How a Roth fits into a broader retirement plan
A Roth IRA is one piece of retirement savings, not a complete plan. If your employer offers a 401(k) or 403(b), you may want to contribute there first, especially if they match your contribution — that match is assistance programs. A Roth IRA is useful for additional savings beyond a workplace plan, or as your primary retirement account if you are self-employed or your employer does not offer a plan.
Many people use both: they contribute to a 401(k) at work for the immediate tax deduction and employer match, then fund a Roth IRA with additional savings for tax-free growth. This combination gives you both a tax deduction now and tax-free withdrawals later, spreading your tax risk across two account types.
Frequently Asked Questions
Can I withdraw my Roth contributions before retirement?
Yes. You can withdraw contributions you have made to a Roth at any time, for any reason, with no penalty and no tax. Only earnings are subject to the age and five-year rules. This makes a Roth more flexible than a traditional IRA if you need access to your money before 59½.
What happens to a Roth when I die?
Your heirs inherit the Roth and can withdraw it tax-free, though they must follow distribution rules based on their relationship to you. A spouse can treat it as their own Roth. Non-spouse heirs must withdraw the balance within 10 years under current rules, but the withdrawals are not taxed.
Do I have to pay taxes on Roth earnings when I withdraw them?
Only if you withdraw earnings before age 59½ and the account has been open less than five years. If you meet both conditions — age 59½ and five-year rule — earnings come out tax-free. If you do not meet both, you owe income tax on the earnings plus a 10% penalty.
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 for 2024 if you are under 50). You can split the money however you want between them, but the limit is per person, not per account type.
What is the difference between a Roth IRA and a Roth 401(k)?
Both use after-tax contributions and offer tax-free withdrawals, but a Roth 401(k) is offered by employers, has higher contribution limits, and requires minimum distributions at age 73. A Roth IRA has lower limits, no required distributions, and stricter income limits on who can contribute directly.
