The annual contribution limits for IRAs and 401(k)s remain consistent regardless of whether the account is Roth or traditional. These limits are periodically adjusted for inflation but can sometimes stay the same year to year.

If your employer offers a 401(k), you may have the option to contribute to a traditional or Roth 401(k). Alternatively, self-employed individuals or freelancers can open IRAs—either Roth or traditional—to save for retirement. The most significant difference lies in the maximum amount you can contribute to each tax-advantaged account.

Key Highlights

• Roth accounts, whether 401(k)s or IRAs, allow your investments to grow tax-free since contributions are made with after-tax dollars.
• Many employers offer Roth 401(k) plans alongside traditional 401(k)s, but not all do.
• Traditional IRAs are funded with pre-tax dollars, offering immediate tax deductions.
• Roth and traditional IRAs are individual accounts available through banks and brokerages, independent of employers.
• Contribution limits for IRAs are significantly lower than those for 401(k) plans.

Understanding Roth 401(k)

Introduced in 2006, the Roth 401(k) combines features of traditional 401(k)s and Roth IRAs, allowing investors to contribute after-tax dollars. Unlike the traditional 401(k), contributions to a Roth 401(k) do not reduce your taxable income upfront, but qualified withdrawals are tax-free.

Offering a Roth 401(k) is optional for employers and requires them to maintain separate accounting for Roth and traditional assets, which can be costly. Employers may also match contributions, but employer matches always go into a traditional 401(k) account and are taxable upon withdrawal.

Roth 401(k) Contribution Limits

• For 2025, the maximum employee contribution is $23,500 with a $7,500 catch-up contribution for those aged 50 and above.
• In 2024, the limits were $23,000 with the same $7,500 catch-up.

According to a Fidelity Investments study, 93.7% of 401(k) plans offered a Roth option in Q2 2024.

What Is a Roth IRA?

Established under the Taxpayer Relief Act of 1997 and named after Senator William Roth, the Roth IRA is an individual retirement account funded with after-tax dollars. Contributions are not typically tax-deductible, but qualified withdrawals are tax-free.

Traditional IRAs contrast with Roth IRAs by allowing pre-tax contributions, which are tax-deductible, but withdrawals are taxed as income.

IRAs are not employer-sponsored; anyone with earned income can open one at financial institutions.

Roth IRA Contribution Limits

For both 2024 and 2025, the maximum contribution is $7,000 annually, with an additional $1,000 catch-up contribution allowed for individuals aged 50 or older, totaling $8,000.

How Contribution Limits Operate

The IRS updates contribution limits annually to reflect inflation adjustments:

• 401(k) plans allow up to $23,500 contributions in 2025, plus $7,500 catch-up for those 50+.
• In 2024, the 401(k) limit was $23,000 with the same catch-up amount.
• Roth IRA contributions max out at $7,000 in 2025, with a $1,000 catch-up.
• These Roth IRA limits remained unchanged from 2024.

Combining Roth and Traditional Accounts

You can contribute to both Roth and traditional 401(k)s or IRAs, but the total contributions must not exceed the annual limits. Splitting contributions between account types is allowed and can be a strategic way to maximize tax advantages.

Investors aiming for maximum tax-advantaged savings often open both Roth 401(k) and Roth IRA accounts to fully utilize combined limits.

Roth IRA Income Eligibility

Roth IRAs impose income limits that restrict or phase out eligibility based on your modified adjusted gross income (MAGI). Higher earners may have reduced or no ability to contribute.

Conversely, Roth 401(k)s have no income limits, making them accessible regardless of earnings.

Combined employee and employer contributions to a Roth 401(k) cannot exceed the lesser of 100% of compensation or $70,000 in 2025 (plus $7,500 catch-up for age 50+), and $69,000 in 2024 (plus $7,500 catch-up).

Income Phase-Out Details for Roth IRA Contributions

• For 2025, individual filers see phase-out begin at $150,000 and end at $165,000; married filing jointly ranges from $236,000 to $246,000.
• In 2024, individual phase-out spans $146,000 to $161,000; married filing jointly ranges from $230,000 to $240,000.

Roth Rollovers Explained

When changing jobs, you can roll over your Roth 401(k) into a new or existing Roth IRA without contribution limits. Ensure the rollover is handled directly between trustees to avoid tax penalties.
