Roth IRA

Stock trading dictionary: meaning, example and how traders use it.

Last updated: October 17, 2026

Definition: A Roth IRA is an individual retirement account funded with after-tax dollars. Investments grow without annual tax, and qualified withdrawals in retirement, including earnings, are free of federal income tax.

How a Roth IRA works

A Roth IRA is a type of individual retirement account. You contribute money you have already paid income tax on, so there is no upfront deduction. Inside the account you can hold stocks, bonds, ETFs, and mutual funds, and you owe no tax on dividends or capital gains as long as the money stays in the account.

The main benefit comes later. Qualified distributions, generally those taken after age 59 1/2 from an account open at least five years, are tax-free. Original owners are not required to take minimum distributions during their lifetime.

Key Roth IRA rules

  • Earned income: you need taxable compensation to contribute.
  • Contribution limits: the IRS sets an annual maximum, with an additional catch-up amount for people 50 and older. The limit is shared with any traditional IRA contributions.
  • Income limits: the ability to contribute directly phases out above income thresholds set by the IRS.
  • Withdrawals of contributions: the amounts you put in can generally be withdrawn at any time without tax or penalty; earnings follow stricter rules.

Rules have exceptions and change over time, so it is worth checking current IRS guidance or a tax professional.

Roth IRA example

Suppose you contribute $5,000 per year for 30 years, a total of $150,000, and the investments earn a hypothetical 6% average annual return. The account would grow to roughly $395,000. In a Roth IRA, a qualified withdrawal of that full balance is free of federal income tax. In a taxable brokerage account, the roughly $245,000 of growth would have been subject to tax on dividends along the way and on gains when sold.

Roth conversions and other considerations

Money in a traditional IRA can generally be converted to a Roth IRA. The converted amount is usually added to taxable income for that year, but future qualified withdrawals become tax-free. Some higher earners who cannot contribute directly use a two-step process often called a backdoor Roth, which has its own tax complexities. Roth accounts can also be useful in estate planning because heirs may inherit tax-free assets, though beneficiaries face their own distribution rules. Because these strategies depend heavily on individual circumstances, many people consult a tax professional first.

Roth IRA vs traditional IRA

With a traditional IRA, contributions may be tax-deductible now, but withdrawals are taxed as ordinary income later. With a Roth, you pay tax now and withdraw tax-free later. A Roth is often favored by people who expect to be in a higher tax bracket in retirement, while a traditional IRA may suit those who expect a lower one. Either way, a long-term portfolio still carries normal investment risks; the tax treatment does not protect against losses.

Frequently asked questions

Can I withdraw from a Roth IRA before 59 1/2?

You can generally withdraw your contributions at any time without tax or penalty. Withdrawing earnings early may trigger income tax and a 10% penalty unless an exception applies.

Who is eligible for a Roth IRA?

You need earned income, and your modified adjusted gross income must be below limits set by the IRS to contribute directly. The limits are adjusted periodically.

Is a Roth IRA better than a traditional IRA?

It depends mainly on whether you expect your tax rate to be higher or lower in retirement than it is today, along with your income, eligibility, and need for flexibility.
