Key Differences Between Roth IRA and Roth 401(k)
- Income limits: Anyone can contribute to a Roth 401(k) regardless of income, while Roth IRA contributions are phased out for individuals with modified adjusted gross income above $150,000 and married couples filing jointly above $236,000 in 2025【143523573419346†L203-L207】.
- Contribution limits: In 2025 you can contribute up to $23,500 to a Roth 401(k), or $31,500 if you’re age 50 or older【143523573419346†L211-L215】. Roth IRA contributions remain capped at $7,000 ($8,000 if you’re 50 or older)【143523573419346†L211-L215】.
- Employer match: Roth 401(k) plans may offer employer matching contributions, which are usually placed in a traditional 401(k) and taxed upon withdrawal【143523573419346†L216-L221】. Roth IRAs do not have an employer match.
- Investment options: With a Roth 401(k), you’re limited to the investment options in your employer’s plan. A Roth IRA typically allows a broader range of investments.
- Required minimum distributions: Beginning in 2024, Roth 401(k) accounts are no longer subject to required minimum distributions (RMDs), but Roth IRAs never require RMDs.
Contribution Limits for 2025
According to Guideline, the standard 401(k) contribution limit increases to $23,500 in 2025, up from $23,000 in 2024, with catch‑up contributions allowing people aged 50‑59 and 64+ to save an extra $7,500 and those aged 60‑63 to save an extra $11,250【836699492085319†L30-L112】. For Roth IRAs, the maximum annual contribution stays at $7,000 ($8,000 for savers aged 50 or older).
Choosing the Right Account
- If you expect your income to increase over time or you’re a high earner who isn’t eligible for a Roth IRA, a Roth 401(k) can provide higher contribution limits and no income restrictions.
- If you want more control over your investments, no RMDs and your income falls below the Roth IRA thresholds, a Roth IRA offers greater flexibility.
- You can contribute to both accounts as long as your total 401(k) contributions don’t exceed the annual limit. Combining a Roth 401(k) and a Roth IRA can give you higher overall contributions and investment flexibility.
Summary
Both Roth IRAs and Roth 401(k)s give you the opportunity for tax‑free growth and withdrawals in retirement. The main differences lie in contribution limits, income eligibility and employer involvement. Consider your income, available retirement plans and desired investment choices to decide which account (or combination of accounts) best supports your financial goals.
