While only about 25% of U.S. households own a Roth IRA, twice as many taxpayers contribute to Roths each year compared to traditional IRAs, with younger savers especially drawn to their tax-free withdrawal benefits
Roth IRAs have become a popular topic in retirement planning, especially among younger workers looking for long-term tax advantages. Yet despite their reputation, Roth IRAs are still less common than traditional IRAs in American households. The difference in how these accounts are used-and who contributes to them-reveals important trends in retirement saving behavior.
According to the Investment Company Institute, only about one in four U.S. households owned a Roth IRA in 2024, while nearly a third held a traditional IRA. This gap is partly explained by the way traditional IRAs are often funded: many are created when workers roll over assets from a 401(k) or similar workplace plan after leaving a job. In fact, ICI data shows that 59% of traditional IRA households have rollover funds, which inflates the number of traditional IRA accounts even as Roth IRAs gain popularity.
Contribution Patterns Diverge
Despite being less common overall, Roth IRAs attract more active contributors each year. IRS data for 2022 shows that about 10 million tax returns reported a Roth IRA contribution, compared to just 5 million for traditional IRAs. With 158 million tax returns filed with income that year, roughly 6.3% of households contributed to a Roth IRA, while only 3.2% contributed to a traditional IRA. This two-to-one ratio is echoed in survey data: among Roth IRA owners, 41% made a contribution in 2023, compared to 21% of traditional IRA owners.
One reason for this difference is that traditional IRAs are often used as a destination for rollovers, not for ongoing annual contributions. Roth IRAs, by contrast, are more likely to be opened specifically for regular contributions, especially by younger savers who expect their income and tax rate to rise over time. The after-tax nature of Roth contributions means qualified withdrawals are tax-free, a feature that appeals to those planning for higher future earnings.
Eligibility and Tax Considerations
Roth IRAs come with specific eligibility rules. To contribute, you must have earned income for the tax year, and higher earners may face income limits that reduce or eliminate their ability to contribute directly. Traditional IRAs, while open to anyone with earned income, offer tax-deductible contributions only to those who meet certain income and workplace retirement plan criteria.
For many savers, the choice between Roth and traditional IRAs hinges on current versus expected future tax rates. Roth IRAs are generally more attractive to younger or midcareer workers who anticipate being in a higher tax bracket later, while traditional IRAs may suit those seeking an immediate tax deduction. According to IRS data, among savers ages 25-29, Roth IRA contributions outnumbered traditional IRA contributions by nearly six to one, highlighting the generational shift toward Roth accounts.
How Roth IRAs Fit Into Broader Retirement Planning
The decision to contribute to a Roth or traditional IRA is just one part of a larger retirement strategy. Many households use a mix of workplace plans, IRAs, and taxable accounts to diversify their tax exposure and withdrawal options in retirement. The flexibility of Roth IRAs-no required minimum distributions during the original owner's lifetime and tax-free withdrawals-can be especially valuable for those seeking to manage taxes in retirement.
Recent research from the Investment Company Institute and IRS underscores the importance of understanding how different retirement accounts are used. For example, a significant share of traditional IRA balances comes from rollovers, not new contributions, which can mask the true level of active saving.

Roth IRAs offer a unique combination of tax treatment and flexibility, but they are not universally available or suitable for every saver. Contribution limits, income thresholds, and the trade-off between current and future tax rates all play a role in determining which account makes sense. Understanding these distinctions can help households make more informed decisions about where to direct their retirement savings and how to balance immediate tax benefits with long-term planning needs.
