Differences between Roth 401(k) and Roth IRA

Roth 401(k) vs. Roth IRA[edit]

Roth 401(k)s and Roth IRAs are tax-advantaged retirement savings accounts in the United States that share a similar tax structure. Both accounts require participants to make contributions with after-tax dollars, which allows for tax-free growth and tax-free withdrawals of earnings during retirement, provided certain conditions are met.[1] Despite these similarities, the accounts are governed by different sections of the Internal Revenue Code, leading to variations in contribution limits, eligibility rules, and administrative control.

Contribution limits and eligibility[edit]

The primary difference between the two accounts is the maximum amount an individual can contribute annually. For the 2024 tax year, the Roth 401(k) limit is $23,000, while the Roth IRA limit is $7,000.[2] In 2025, the Roth 401(k) limit increases to $23,500, but the Roth IRA limit remains unchanged.[3]

Roth IRAs include income restrictions that prevent high-earners from contributing directly. In 2024, the ability to contribute to a Roth IRA begins to phase out for single filers with a modified adjusted gross income (MAGI) of $146,000.[4] Roth 401(k) plans do not have income caps for participation, though "highly compensated employees" may face contribution restrictions if the employer's plan fails specific non-discrimination testing.

Administrative differences and withdrawals[edit]

A Roth 401(k) is an employer-sponsored plan, meaning the employer selects the financial institution that holds the assets and determines the available investment options. Most plans offer a curated selection of mutual funds or target-date funds. In contrast, a Roth IRA is opened by an individual at a brokerage of their choice, providing access to a wider range of stocks, bonds, and exchange-traded funds (ETFs).

Withdrawal rules also vary. Roth IRA owners can withdraw their original contributions at any time without taxes or penalties. Roth 401(k) withdrawals generally require a "triggering event," such as reaching age 59½ or leaving the employer. However, many 401(k) plans allow participants to take loans against their balance, an option not available with IRAs. Under the SECURE 2.0 Act, Roth 401(k) accounts are no longer subject to required minimum distributions (RMDs) starting in 2024, aligning them with the long-standing RMD exemption for Roth IRA owners.[5]
