A Roth IRA is a type of individual retirement account available to people in the United States who have earned income. Contributions are made with money that has already been taxed, so they bring no tax deduction in the year they are paid in. In return, the investments inside the account grow without tax, and withdrawals that meet the rules in retirement are completely tax-free, including the growth.
The account was created by the Taxpayer Relief Act of 1997 and named after Senator William Roth of Delaware, who championed it. It is the main alternative to a traditional IRA, which gives a deduction now but taxes withdrawals later. It is one of several tax-favoured ways to build a retirement fund in the US. Roth accounts are regulated by the Internal Revenue Service and are offered by banks, brokers and specialist custodians. A Roth option also exists inside many workplace plans such as the 401(k) plan.
The Roth IRA in plain terms
Imagine a farmer who can pay tax either on a bag of seeds or on the harvest that grows from them. A traditional IRA taxes the harvest; a Roth IRA taxes the seeds. If the harvest turns out to be big, paying tax on the seeds instead was the better deal.
So the Roth asks you to pay tax today in exchange for never paying it on the account again, as long as you follow the rules. It tends to suit people who expect their tax rate to be the same or higher later, and people with many years for their savings to grow.
How a Roth IRA works
The main rules, as they stood in November 2026, are:
- Eligibility. The saver must have taxable earned income, such as wages or self-employment income. Direct contributions are reduced and then ruled out above income thresholds that the IRS adjusts each year.
- Annual limit. Contributions to all of a person's IRAs combined are capped each year, with an extra catch-up amount for those aged 50 and over. For 2025 the limit was 7,000 dollars plus a 1,000-dollar catch-up; readers should check the IRS for later years.
- Qualified withdrawals. Earnings can be taken out tax-free and penalty-free once the owner is at least 59½ and the account has been open for five years, or in cases such as disability or death.
- Access to contributions. The amount originally paid in can be withdrawn at any time without tax or penalty, because it was already taxed.
- No required withdrawals. Unlike a traditional IRA, the original owner does not have to take minimum distributions during their lifetime.
Roth IRA compared with a traditional IRA
| Feature | Roth IRA | Traditional IRA |
|---|---|---|
| Tax on contributions | Paid now, no deduction | Often deductible now |
| Tax on growth | None if rules are met | Deferred until withdrawal |
| Tax on retirement withdrawals | None if qualified | Taxed as ordinary income |
| Lifetime minimum withdrawals | None for the owner | Required from a set age |
The choice largely depends on whether a saver's marginal tax rate is expected to be higher now or in retirement, and on the value of tax-free compound growth over long periods.
Conversions and the backdoor Roth
Money in a traditional IRA can be converted to a Roth IRA by paying income tax on the amount converted. Since 2010 there has been no income limit on conversions, which led to the "backdoor Roth": higher earners who cannot contribute directly make a non-deductible traditional IRA contribution and then convert it. The strategy is legal but has tax traps, such as the pro-rata rule when other pre-tax IRA money exists, so many savers take professional advice.
Crypto and alternative assets in a Roth IRA
Roth IRAs can hold shares, bonds, funds and, through self-directed accounts with specialist custodians, assets such as real estate and cryptocurrency. Since US spot bitcoin ETFs began trading in January 2024, many savers have gained crypto exposure through ordinary brokerage IRAs instead. Because gains in a Roth are never taxed if the rules are met, holding volatile, high-growth assets there is sometimes promoted, but losses cannot be deducted either, and self-directed accounts carry higher fees and the risk of prohibited transactions. The IRS treats crypto as property for capital gains tax purposes outside retirement accounts.
Limitations
A Roth IRA's benefits depend on future tax law staying broadly the same, and the up-front tax cost can be a burden for savers with little spare cash. Income limits restrict direct use by high earners, and early withdrawal of earnings normally brings both tax and a 10% penalty. A Roth IRA can be a useful estate planning tool, but heirs who inherit one usually must empty it within ten years under rules introduced in 2019, though withdrawals are generally tax-free. Nothing here is personal tax or investment advice.
