A Roth IRA is a retirement savings account where you contribute money after taxes, and then withdraw it tax-free in retirement

A Roth IRA is an individual retirement account that works backwards from a traditional IRA. You put in money that you've already paid income tax on, the money grows over decades, and when you reach retirement age, you pull it out without owing any federal income tax on the growth or the withdrawals themselves. The trade-off is that you don't get a tax deduction in the year you contribute—but the decades of tax-free growth often make up for it.

The account is named after Senator William Roth, who sponsored the legislation that created it in 1997. It's offered by banks, brokerages, and investment firms, and you control what goes inside it—stocks, bonds, mutual funds, or cash. The IRS sets contribution limits each year (the limit changes periodically and varies by age), and there are income limits that determine whether you can contribute at all.

Key Takeaways

  • You contribute money you've already paid taxes on, so contributions are not tax-deductible, but withdrawals in retirement are completely tax-free.
  • Your money grows tax-free inside the account for decades, meaning you don't owe taxes on investment gains, dividends, or interest.
  • The IRS sets annual contribution limits and income limits—if your income is too high, you cannot contribute directly to a Roth IRA.
  • You can withdraw your contributions (the money you put in) at any time without penalty, but earnings withdrawn before age 59½ usually trigger taxes and a 10% penalty.
  • Unlike a traditional IRA, there are no required minimum withdrawals at any age, so your money can keep growing as long as you leave it alone.

How contributions and tax treatment work

When you put money into a Roth IRA, you use after-tax dollars—money you've already paid federal income tax on through your paycheck or other income. The IRS does not let you deduct that contribution from your taxable income in the year you make it. If you earn $50,000 and contribute $7,000 to a Roth IRA, your taxable income for that year is still $50,000.

The benefit comes later. Every dollar your money earns inside the account—through stock gains, bond interest, dividend payments, or any other investment return—is never taxed. When you turn 59½ and have owned the account for at least five years, you can withdraw everything: your original contributions, all the growth, all the earnings, completely tax-free. That tax-free growth is the core reason people choose a Roth over other accounts.

Income limits and who can contribute

The IRS limits who can contribute to a Roth IRA based on your modified adjusted gross income (MAGI). The income thresholds change each year and depend on your filing status—single, married filing jointly, married filing separately, or head of household. If your income falls below the threshold, you can contribute the full annual limit. If it falls within a phase-out range, you can contribute a reduced amount. If it exceeds the upper limit, you cannot contribute directly.

These limits exist because the Roth is considered a tax benefit for lower and middle-income savers. High earners can still fund a Roth through a "backdoor Roth" strategy—contributing to a traditional IRA and then converting it to a Roth—but that involves additional tax calculations and is not the straightforward path. Your brokerage or bank can tell you the current year's limits and whether your income qualifies.

Contribution limits and catch-up contributions

The annual contribution limit is set by Congress and adjusted for inflation most years. For 2024, the limit is $7,000 for people under 50 and $8,000 for people 50 and older (the extra $1,000 is called a catch-up contribution). These limits apply across all your IRAs combined—if you have both a Roth and a traditional IRA, your total contributions to both cannot exceed the annual limit.

You can contribute at any time during the year, and you have until the tax filing deadline (usually April 15 of the following year) to make a contribution and have it count toward the previous year's limit. Many people contribute in chunks throughout the year rather than all at once, but the deadline is flexible as long as you file your taxes on time.

Withdrawal rules: contributions versus earnings

The Roth has a unique feature: you can withdraw your contributions (the money you put in) at any time, for any reason, without taxes or penalties. If you contributed $50,000 over ten years and need $10,000 for an emergency, you can take it out. The IRS considers that money yours because you already paid tax on it.

Earnings—the investment gains and growth inside the account—are treated differently. If you withdraw earnings before age 59½, you owe federal income tax on them plus a 10% early withdrawal penalty, with some exceptions. Those exceptions include first-time home purchases (up to $10,000 lifetime), certain medical expenses, disability, and a few others. The five-year rule also applies: you must have owned the Roth for at least five tax years before you can withdraw earnings tax-free, even after age 59½.

No required minimum withdrawals

A traditional IRA forces you to start withdrawing money at age 73 (as of 2023; the age has been rising gradually). A Roth IRA has no such requirement. You can leave your money in the account for your entire life, letting it compound tax-free, and never take a withdrawal if you don't need to. This makes a Roth a powerful tool for building wealth across decades and for leaving money to heirs.

Your beneficiaries will inherit the account and can withdraw it tax-free (though they must follow their own withdrawal timeline under current rules). This tax-free inheritance is another reason people favor a Roth for long-term wealth building.

Roth conversion and backdoor Roth strategies

If your income is too high to contribute directly to a Roth, you have other paths. A Roth conversion means moving money from a traditional IRA (or a 401(k) at some employers) into a Roth IRA. You pay income tax on the amount you convert in that year, but the money then grows tax-free in the Roth. A backdoor Roth is a specific strategy: you contribute to a non-deductible traditional IRA, then immediately convert it to a Roth, paying minimal tax because the money hasn't grown yet.

These strategies are legal but involve tax calculations and timing. If you earn above the Roth income limits, talking to a tax professional before executing a conversion is worth the cost, because mistakes can be expensive. Your brokerage can walk you through the mechanics, but the tax consequences are your responsibility.

Frequently Asked Questions

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

Yes, you can have both accounts. However, your total contributions to all IRAs combined cannot exceed the annual limit. If you contribute $4,000 to a Roth, you can only contribute $3,000 to a traditional IRA that year (assuming the limit is $7,000). The accounts are separate, but the contribution limit is shared.

What happens if I withdraw money before age 59½?

You can withdraw your contributions anytime without penalty. If you withdraw earnings before 59½, you owe income tax on them plus a 10% penalty, unless an exception applies (first-time home purchase, disability, medical hardship, etc.). The five-year rule also applies—the account must be open for at least five tax years before earnings can be withdrawn tax-free.

Is a Roth IRA the same as a Roth 401(k)?

No. A Roth IRA is an individual account you open yourself. A Roth 401(k) is an employer retirement plan. Both use after-tax contributions and offer tax-free growth, but Roth 401(k)s have higher contribution limits, require minimum withdrawals at age 73, and are only available through your employer. A Roth IRA is available to anyone with earned income below the income limits.

What if my income changes and I exceed the limit mid-year?

If you contribute and then your income rises above the limit, you have until the tax filing deadline to withdraw the excess contribution plus any earnings on it. If you don't, the IRS charges a 6% penalty each year the excess sits in the account. Your brokerage can help you calculate and execute an excess contribution withdrawal.

Can I use a Roth IRA if I'm self-employed?

Yes. A Roth IRA is available to anyone with earned income, including self-employed people. However, self-employed people often benefit more from a Solo 401(k) or SEP IRA because those allow much higher contributions. You can have both a Roth IRA and a Solo 401(k), but again, contribution limits are shared across IRAs only—the Solo 401(k) has its own separate limit.
